Growing evidence supports the safety of a laparoscopic approach for patients affected by apparent early-stage ovarian cancer. However, no well-designed studies comparing laparoscopic and open surgical staging are available. In the present investigation we aimed to provide a balanced long-term comparison between these 2 approaches. Retrospective study (Canadian Task Force classification II-2). Tertiary center. Data of consecutive patients affected by early-stage ovarian cancer who had laparoscopic staging were matched 1:1 with a cohort of patients undergoing open surgical staging. The matching was conducted by a propensity-score comparison. Laparoscopic and open surgical staging. Fifty patient pairs (100 patients: 50 undergoing laparoscopic staging vs 50 undergoing open surgical staging) were included. Demographic and baseline oncologic characteristics were balanced between groups (p > .2). We observed that patients undergoing laparoscopic staging experienced longer operative time (207.2 [71.6] minutes vs 180.7 [47.0] minutes; p = .04), lower blood loss (150 [52.7] mL vs 339.8 [225.9] mL; p < .001), and shorter length of hospital stay (4.0 [2.6] days vs 6.1 [1.6] days; p < .001) compared with patients undergoing open surgical staging. No conversion to open surgery occurred. Complication rate was similar between groups. No difference in survival outcomes were observed, after a mean (SD) follow-up of 49.5 (64) and 52.6 (31.7) months after laparoscopic and open surgical staging, respectively. Our findings suggest that the implementation of minimally invasive staging does not influence survival outcomes of patients affected by early-stage ovarian cancer. Laparoscopic staging improved patient outcomes, reducing length of hospital stay. Further large prospective studies are warranted. Copyright © 2016 AAGL. Published by Elsevier Inc.

OBJECTIVE To compare outcomes for laparoscopic ovariectomy (LapOVE) and laparoscopic-assisted ovariohysterectomy (LapOVH) in dogs. DESIGN Retrospective case series. ANIMALS 278 female dogs. PROCEDURES Medical records of female dogs that underwent laparoscopic sterilization between 2003 and 2013 were reviewed. History, signalment, results of physical examination, results of preoperative diagnostic testing, details of the surgical procedure, durations of anesthesia and surgery, intraoperative and immediate postoperative (ie, during hospitalization) complications, and short- (≤ 14 days after surgery) and long-term (> 14 days after surgery) outcomes were recorded. Data for patients undergoing LapOVE versus LapOVH were compared. RESULTS Intraoperative and immediate postoperative complications were infrequent, and incidence did not differ between groups. Duration of surgery for LapOVE was significantly less than that for LapOVH; however, potential confounders were not assessed. Surgical site infection was identified in 3 of 224 (1.3%) dogs. At the time of long-term follow-up, postoperative urinary incontinence was reported in 7 of 125 (5.6%) dogs that underwent LapOVE and 12 of 82 (14.6%) dogs that underwent LapOVH. None of the dogs had reportedly developed estrus or pyometra by the time of final follow-up. Overall, 205 of 207 (99%) owners were satisfied with the surgery, and 196 of 207 (95%) would consider laparoscopic sterilization for their dogs in the future. CONCLUSIONS AND CLINICAL RELEVANCE Results suggested that short- and long-term outcomes were similar for female dogs undergoing sterilization by means of LapOVE or LapOVH; however, surgery time may have been shorter for dogs that underwent LapOVE. Most owners were satisfied with the outcome of laparoscopic sterilization.

The aim of this study was to compare the early postoperative outcome of patients undergoing laparoscopic subtotal colectomy with those undergoing open subtotal colectomy for colitis refractory to medical treatment. A retrospective observational study was carried out of patients who underwent subtotal colectomy for refractory colitis, at a single centre, between 2006 and 2012. Patients were matched for age, gender, American Society of Anesthesiology (ASA) grade, urgency of operation and immunosuppressant/modulator treatment. The primary outcome measure was the number of postoperative complications, classified using the Clavien-Dindo scale. Secondary end-points included procedure duration, laparoscopic conversion rates, blood loss, 30-day readmission rates and length of hospital stay. Ninety-six patients were included, 39 of whom had laparoscopic surgery. Thirty-two of these were matched to similar patients who underwent an open procedure. The overall duration of the procedure was longer for laparoscopic surgery than for open surgery (median: 240 vs 150 min, P < 0.005) but estimated blood loss was less (median: 75 vs 400 ml, P < 0.005). In the laparoscopic group, 23 patients experienced 27 complications, and in the open surgery group, 23 patients experienced 30 complications. Most complications were minor (Grade I/II), and the distribution of complications, by grade, was similar between the two groups. There was no statistically significant difference in 30-day readmission rates between the laparoscopic and open groups (five readmissions vs eight readmissions, P = 0.536). Length of hospital stay was 4 days shorter for laparoscopic surgery, but this difference was not statistically significant (median: 7 vs 11 days, P = 0.159). In patients requiring colectomy for acute severe colitis, laparoscopic surgery reduced blood loss but increased operating time and was not associated with a reduction in early postoperative complications, length of hospital stay or readmission rates.

There is a paucity of literature describing the association of age with the risk of adverse events following bariatric surgery. The purpose of this study is to investigate the association of age with 30-day morbidity and mortality following laparoscopic bariatric surgery using the Metabolic and Bariatric Surgery Accreditation and Quality Improvement Program (MBSAQIP) database. All adult patients undergoing laparoscopic Roux-en-Y gastric bypass (RNGYB) or sleeve gastrectomy (SG) were identified within the MBSAQIP database. Patients were divided into five equal age quintiles. Binary outcomes of interest, including cardiac, pulmonary, wound, septic, clotting, and renal events, in addition to the incidence of related 30-day unplanned reintervention, related 30-day mortality, and a composite morbidity and mortality outcome were compared across the age quintiles and procedures. A total of 266,544 patients met inclusion criteria. Older age was associated with an increased risk of all morbidity outcomes except venous thromboembolism events, 30-day mortality, and the composite morbidity and mortality outcome. Patients who underwent Roux-en-Y gastric bypass had worse outcomes per quintile for almost every outcome of interest when compared to patients who underwent sleeve gastrectomy. Older patients and patients who undergo Roux-en-Y gastric bypass are at an increased risk of perioperative morbidity and mortality following laparoscopic bariatric surgery. Additional studies are needed to determine the association of age with long-term weight loss and cardiometabolic comorbidity resolution following bariatric surgery in order to determine if the increased perioperative risk is offset by improved long-term outcomes in older patients undergoing bariatric surgery.

In a minority of patients undergoing antireflux surgery, an esophageal lengthening procedure is required to reduce the gastroesophageal junction (GEJ) below the esophageal hiatus. We evaluated risk factors associated with an irreducible GEJ to identify clinical features that were predictive of the need for a Collis gastroplasty in patients undergoing laparoscopic antireflux surgery. Patients who required a Collis gastroplasty during a laparoscopic antireflux procedure (defined as the inability to reduce the GEJ > 2.5 cm below the esophageal hiatus despite extensive mobilization of the mediastinal esophagus) were compared to a random sample of patients who did not have a Collis gastroplasty. Predictors of the need for an esophageal lengthening procedure were identified using logistic regression modeling. Risks were expressed as odds ratios (OR) and 95% confidence intervals (CI). Twenty patients who had a Collis gastroplasty were compared to 133 patients who had adequate esophageal length. The presence of a stricture (OR 3.0; 95% CI 1.0, 9.7), paraesophageal hernia (OR 3.5; 95% CI 1.3, 9.6), Barrett's esophagus (OR 3.7, 95% CI 1.3, 10.7), and re-do antireflux surgery (OR 6.4; 95% CI 2.0, 20.7) were associated with the need for gastroplasty. Patients with none of these factors were extremely unlikely to require a gastroplasty (OR 0.08; 95% CI 0.02, 0.34). Patients undergoing laparoscopic antireflux surgery who are at high risk of needing an esophageal lengthening procedure can be easily identified preoperatively using simple clinical characteristics.

Laparoendoscopic single-site (LESS) surgery is beginning to include advanced laparoscopic operations such as Heller myotomy with anterior fundoplication. However, the efficacy of LESS Heller myotomy has not been established. This study aimed to evaluate the authors' initial experience with LESS Heller myotomy for achalasia. Transumbilical LESS Heller myotomy with concomitant anterior fundoplication for achalasia was undertaken for 66 patients after October 2007. Outcomes including operative time, complications, and length of hospital stay were recorded and compared with those for an earlier contiguous group of 66 consecutive patients undergoing conventional multi-incision laparoscopic Heller myotomy with anterior fundoplication. Symptoms before and after myotomy were scored by the patients using a Likert scale ranging from 0 (never/not severe) to 10 (always/very severe). Data were analyzed using the Mann-Whitney U test, the Wilcoxon matched-pairs test, and Fisher's exact test where appropriate. Patients undergoing LESS Heller myotomy were similar to those undergoing conventional laparoscopic Heller myotomy in gender, age, body mass index (BMI), blood loss, and length of hospital stay. However, the patients undergoing LESS Heller myotomies had operations of significantly longer duration (median, 117 vs. 93 min with the conventional laparoscopic approach) (p<0.003). For 11 patients (16%) undergoing LESS Heller myotomy, additional ports/incisions were required. No patients were converted to "open" operations, and no patients had procedure-specific complications. Symptom reduction was dramatic and satisfying after both LESS and conventional laparoscopic myotomy with fundoplication. The symptom reduction was similar with the two procedures. The LESS approach left no apparent umbilical scar. Heller myotomy with anterior fundoplication effectively treats achalasia. The findings showed LESS Heller myotomy with anterior fundoplication to be feasible, safe, and efficacious. Although the LESS approach increases operative time, it does not increase procedure-related morbidity or hospital length of stay and avoids apparent umbilical scarring. Laparoendoscopic single-site surgery represents a paradigm shift to more minimally invasive surgery and is applicable to advanced laparoscopic operations such as Heller myotomy and anterior fundoplication.

Colorectal cancer is the second most common cause of death from neoplastic disease in men and third in women of all ages. Globally, life expectancy is increasing, and consequently, an increasing number of operations are being performed on more elderly patients with the trend set to continue. Elderly patients are more likely to have cardiovascular and pulmonary comorbidities that are associated with increased peri-operative risk. They further tend to present with more locally advanced disease, more likely to obstruct or have disseminated disease. The aim of this review was to investigate the feasibility of laparoscopic colorectal resection in very elderly patients, and whether there are benefits over open surgery for colorectal cancer. A systematic literature search was performed on Medline, Pubmed, Embase and Google Scholar. All comparative studies evaluating patients undergoing laparoscopic versus open surgery for colorectal cancer in the patients population over 85 were included. The primary outcomes were 30-day mortality and 30-day overall morbidity. Secondary outcomes were operating time, time to oral diet, number of retrieved lymph nodes, blood loss and 5-year survival. The search provided 1507 citations. Sixty-nine articles were retrieved for full text analysis, and only six retrospective studies met the inclusion criteria. Overall mortality for elective laparoscopic resection was 2.92% and morbidity 23%. No single study showed a significant difference between laparoscopic and open surgery for morbidity or mortality, but pooled data analysis demonstrated reduced morbidity in the laparoscopic group (p = 0.032). Patients undergoing laparoscopic surgery are more likely to have a shorter hospital stay and a shorter time to oral diet. Elective laparoscopic resection for colorectal cancer in the over 85 age group is feasible and safe and offers similar advantages over open surgery to those demonstrated in patients of younger ages.

To examine whether the addition of narrow band imaging (NBI) to traditional white light imaging during laparoscopic surgery impacts pain and quality of life (QOL) at 3 and 6 months after surgery among women with suspected endometriosis and/or infertility. A randomized controlled trial (Canadian Task Force classification level I). The trial was conducted in 2 medical centers. From October 2011 to November 2013, 167 patients undergoing laparoscopic examination for suspected endometriosis and/or infertility were recruited. The analytic study sample includes 148 patients with pain and QOL outcome data. Patients were randomized in a 3:1 ratio to receive white light imaging followed by NBI (WL/NBI) or white light imaging only (WL/WL). Questionnaires were administered at baseline and at 3- and 6-month follow-up time points. Average and most severe pain at each time point were assessed using a 10-cm visual analog scale. QOL was measured using the Endometriosis Health Profile-30. Baseline characteristics were similar for the study groups. The WL/NBI and WL/WL groups had similar reductions in pain at 3 and 6 months. In addition, QOL improved similarly for both the WL/NBI and WL/WL groups at 3 and 6 months. Laparoscopic surgery for suspected endometriosis is associated with a reduction in pain and an improvement in QOL. The differences in pain reduction and QOL improvement, which are noted at 3 months and remain stable at 6 months after surgery, are similar for those undergoing surgery with WL/NBI compared with those undergoing surgery under traditional white light conditions.

In contrast to the significant advantages of laparoscopic versus open gastrectomy, robotic gastrectomy has shown little benefit over laparoscopic gastrectomy. This study aimed to compare multi-dimensional aspects of surgical outcomes after open, laparoscopic, and robotic gastrectomy. Data from 915 gastric cancer patients who underwent gastrectomy by one surgeon between March 2009 and May 2015 were retrospectively reviewed. Perioperative parameters were analyzed for short-term outcomes. Surgical success was defined as the absence of conversion to open surgery, major complications, readmission, positive resection margin, or fewer than 16 retrieved lymph nodes. This study investigated 241 patients undergoing open gastrectomy, 511 patients undergoing laparoscopic gastrectomy, and 173 patients undergoing robotic gastrectomy. For each approach, the respective incidences were as follows: conversion to open surgery (not applicable, 0.4%, and 0%; p = 0.444), in-hospital major complications (5.8, 2.7, and 1.2%; p = 0.020), delayed complications requiring readmission (2.9, 2.0, and 1.2%; p = 0.453), positive resection margin (1.7, 0, and 0%; p = 0.003), and inadequate number of retrieved lymph nodes (0.4, 4.1, and 1.7%; p = 0.010). Compared with open and laparoscopic surgery, robotic gastrectomy had the highest surgical success rate (90, 90.8, and 96.0%). Learning-curve analysis of success using cumulative sum plots showed success with the robotic approach from the start. Multivariate analyses identified age, sex, and gastrectomy extent as significant independent parameters affecting surgical success. Surgical approach was not a contributing factor. Open, laparoscopic, and robotic gastrectomy exhibited different incidences and causes of surgical failure. Robotic gastrectomy produced the best surgical outcomes, although the approach method itself was not an independent factor for success.

One of the most frequent complications after laparoscopic antireflux surgery is intrathoracic migration of the wrap ("slipped" Nissen fundoplication). The most common reasons for this are inadequate closure of the crura or disruption of the crural closure. The aim of this prospective study was to evaluate surgical outcomes in patients who underwent laparoscopic antireflux surgery with simple nonabsorbable polypropylene sutures for hiatal closure in comparison to patients who underwent routine mesh-hiatoplasty. Between 1993 and 1998, a group of 361 patients underwent primary laparoscopic Nissen or Toupet fundoplication with the use of simple nonabsorbable polypropylene sutures for hiatal closure. Since December 1998, in all patients (n = 170) who underwent laparoscopic antireflux surgery, a 1 x 3 cm polypropylene mesh was placed on the crura behind the esophagus to reinforce them. Functional outcome, symptoms of gastroesophageal reflux disease, and postoperative complications such as recurrent hiatal hernia with or without intrathoracic migration of the wrap have been used for assessment of outcomes. In the initial series of 361 patients, postoperative herniation of the wrap occurred in 22 patients (6.1%). Of these 22 patients, 17 of them (4.7%) had to undergo laparoscopic redo surgery. The remaining five patients were free of symptoms. In comparison to these results, in a second group of 170 patients there was only one (0.6%) who had postoperative herniation of the wrap into the chest. There have been no significant differences in objective data such as DeMeester scores or lower esophageal sphincter pressure between the two groups. Postoperative dysphagia was increased during the early period after surgery in patients undergoing mesh-hiatoplasty but resolved without any further treatment within the first year after laparoscopic antireflux surgery. We concluded that routine hiatoplasty with the use of a polypropylene mesh is effective in preventing postoperative herniation of the wrap and leads to a significantly better surgical outcome than closure of the hiatal crura with simple sutures, without any additional long-term side effects.

Laparoscopic adrenalectomy is considered the standard technique for the surgical removal of the adrenal gland. This report is about a 4-year single experience in our Endocrine and General Surgery Unit with laparoscopic adrenalectomy. A total of 24 lateral transperitoneal laparoscopic adrenalectomies were performed. The indications for laparoscopic surgery were: aldosteronoma in 3 patients, pheochromocytoma in 6 patients, nonfunctioning adenoma in 6 patients, adenoma causing Cushing's syndrome in 3 patients, 1 lymphangioma-like adenomatoid tumor, 1 myelolipoma, 1 complicated adrenal cyst, 2 adrenocortical carcinomas, 1 lung metastasis. All except two had successful laparoscopic adrenalectomy. Complication occurred in one patient. 3 patients underwent other associated laparoscopic procedures. Operative time ranged from 100 to 240 minutes for laparoscopic adrenalectomy, from 180 to 210 minutes in the cases with two associated laparoscopic procedures, 5 hours for bilateral adrenalectomy; the postoperative hospital stay for laparoscopic adrenalectomy ranged from 4 to 8 days (6,79 days) and from 7 to 13 days (9,12 days) for patients undergoing the open or converted procedure. Laparoscopic adrenalectomy is technically feasible and reproducible. We evaluate the effectiveness of laparoscopic adrenalectomy for a variety of endocrine disorders except in the case of invasive carcinoma or large masses. Antonio Cardarelli Endocrine and General Surgery Unit in Naples is known as a specialized center for thyroid and parathyroid surgery; in future, we could also become a high-volume laparoscopic referral center for adrenal gland pathologies.

The pain following gynecological laparoscopic surgery is less intense than that following open surgery; however, patients often experience visceral pain after the former surgery. The aim of this study was to determine the effects of preemptive ketamine on visceral pain in patients undergoing gynecological laparoscopic surgery. Ninety patients undergoing gynecological laparoscopic surgery were randomly assigned to one of three groups. Group 1 received placebo. Group 2 was intravenously injected with preincisional saline and local infiltration with 20 mL ropivacaine (4 mg/mL) at the end of surgery. Group 3 was intravenously injected with preincisional ketamine (0.3 mg/kg) and local infiltration with 20 mL ropivacaine (4 mg/mL) at the end of surgery. A standard anesthetic was used for all patients, and meperidine was used for postoperative analgesia. The visual analogue scale (VAS) scores for incisional and visceral pain at 2, 6, 12, and 24 h, cumulative analgesic consumption and time until first analgesic medication request, and adverse effects were recorded postoperatively. The VAS scores of visceral pain in group 3 were significantly lower than those in group 2 and group 1 at 2 h and 6 h postoperatively (P<0.05 and P<0.01, respectively). At 2 h and 6 h, the VAS scores of incisional pain did not differ significantly between groups 2 and 3, but they were significantly lower than those in group 1 (P<0.01). Groups 1 and 2 did not show any differences in visceral pain scores at 2 h and 6 h postoperatively. Moreover, the three groups showed no statistically significant differences in visceral and incisional pain scores at 12 h and 24 h postoperatively. The consumption of analgesics was significantly greater in group 1 than in groups 2 and 3, and the time to first request for analgesics was significantly longer in groups 2 and 3 than in group 1, with no statistically significant difference between groups 2 and 3. However, the three groups showed no significant difference in the incidence of shoulder pain or adverse effects. Preemptive ketamine may reduce visceral pain in patients undergoing gynecological laparoscopic surgery.

Background There is no adequate evidence on how the long duration of laparoscopic surgery affects splanchnic perfusion in elderly patients or the efficacy of acute hypervolemic fluid infusion (AHFI) during the induction of anesthesia. Our aim was to observe the effects of AHFI during the induction of general anesthesia on splanchnic perfusion. Material/Methods Seventy elderly patients receiving laparoscopic colorectal surgery were randomly divided into three groups: lactated Ringer’s solution group (group R), succinylated gelatin group (group G), and hypertonic sodium chloride hydroxyethyl starch 40 injection group (group H). Thirty minutes after the induction of general anesthesia, patients received an infusion of target dose of these three solutions. Corresponding hemodynamic parameters, arterial blood gas analysis, and gastric mucosal carbon dioxide tension were monitored in sequences. Results In all three groups, gastric-arterial partial CO2 pressure gaps (Pg–aCO2) were decreased at several beginning stages and then gradually increased, Pg–aCO2 also varied between groups due to certain time points. The pH values of gastric mucosa (pHi) decreased gradually after the induction of pneumoperitoneum in the three groups. Conclusions The AHFI of succinylated gelatin (12 ml/kg) during the induction of anesthesia can improve splanchnic perfusion in elderly patients undergoing laparoscopic surgery for colorectal cancer and maintain good splanchnic perfusion even after a long period of pneumoperitoneum (60 minutes). AHFI can improve splanchnic perfusion in elderly patients undergoing laparoscopic colorectal surgery. PMID:29382813

The evolving application of single-port robotic surgery in general surgery.

Advances in the field of minimally invasive surgery have grown since the original advent of conventional multiport laparoscopic surgery. The recent development of single incision laparoscopic surgery remains a relatively novel technique, and has had mixed reviews as to whether it has been associated with lower pain scores, shorter hospital stays, and higher satisfaction levels among patients undergoing procedures through cosmetically-appeasing single incisions. However, due to technical difficulties that arise from the clustering of laparoscopic instruments through a confined working space, such as loss of instrument triangulation, poor surgical exposure, and instrument clashing, uptake by surgeons without a specific interest and expertise in cutting-edge minimally invasive approaches has been limited. The parallel use of robotic surgery with single-port platforms, however, appears to counteract technical issues associated with single incision laparoscopic surgery through significant ergonomic improvements, including enhanced instrument triangulation, organ retraction, and camera localization within the surgical field. By combining the use of the robot with the single incision platform, the recognized challenges of single incision laparoscopic surgery are simplified, while maintaining potential advantages of the single-incision minimally invasive approach. This review provides a comprehensive report of the evolving application single-port robotic surgery in the field of general surgery today. © 2013 Japanese Society of Hepato-Biliary-Pancreatic Surgery.

One of the major advantages for patients undergoing minimally invasive surgery as compared to an open surgical procedure is the improved recovery profile and decreased opioid requirements in the perioperative period. There are no definitive studies comparing the analgesic requirements in patients undergoing two different types of minimally invasive procedure. This study retrospectively compares the perioperative analgesic requirements in severely obese adolescents and young adults undergoing laparoscopic versus robotic-assisted, laparoscopic gastric sleeve resection. With Institutional Review Board approval, the medication administration records of all severely obese patients who underwent gastric sleeve resection were retrospectively reviewed. Intra-operative analgesic and adjuvant medications administered, postoperative analgesic requirements, and visual analog pain scores were compared between those undergoing a laparoscopic procedure versus a robotic-assisted procedure. This study cohort included a total of 28 patients who underwent gastric sleeve resection surgery with 14 patients in the laparoscopic group and 14 patients in the robotic-assisted group. Intra-operative adjuvant administration of both intravenous acetaminophen and ketorolac was similar in both groups. Patients in the robotic-assisted group required significantly less opioid during the intra-operative period as compared to patients in the laparoscopic group (0.15 ± 0.08 mg/kg vs. 0.19 ± 0.06 mg/kg morphine, P = 0.024). Cumulative opioid requirements for the first 72 postoperative h were similar in both the groups (0.64 ± 0.25 vs. 0.68 ± 0.27 mg/kg morphine, P = NS). No difference was noted in the postoperative pain scores. Although intraoperative opioid administration was lower in the robotic-assisted group, the postoperative opioid requirements, and the postoperative pain scores were similar in both groups.

Risk of anastomotic leak after laparoscopic versus open colectomy.

Anastomotic leak following colorectal surgery is associated with significant morbidity and mortality. With the widespread adoption of laparoscopy, data from initial clinical trials evaluating the efficacy of laparoscopic when compared to open surgery may not currently be generalizable. We assess the risk of anastomotic leak after laparoscopic versus open colorectal resection using a nationwide database with standardized definitions. The 2012-2013 ACS-NSQIP targeted colectomy data were queried for all elective colorectal resections. Characteristics were compared for those patients undergoing laparoscopic versus open operations. Univariable and multivariable analyses, followed by a propensity score-matched analysis, were performed to assess the impact of laparoscopy on the development of an anastomotic leak. Of 23,568 patients, 3.4 % developed an anastomotic leak. Laparoscopic surgery was associated with a leak rate of 2.8 % (n = 425) and open surgery, 4.5 % (n = 378, p < 0.0001). Patients who developed a leak were more likely to die within 30 days of surgery (5.7 vs. 0.6 %, p < 0.0001). Patients who underwent laparoscopic surgery compared to open were younger (61 vs. 63 years, p = 0, p = 0.045) and with fewer comorbidities. On univariable analysis laparoscopic surgery was associated with reduced odds of developing an anastomotic leak (OR 0.60, p < 0.0001), and this remained after adjusting for all significant preoperative and disease-related confounders (OR 0.69, 95 % CI 0.58-0.82). A propensity score-matched analysis confirmed benefit of laparoscopic surgery over open surgery for anastomotic leak. Laparoscopic colectomy is safe and associated with reduced odds of developing an anastomotic leak following colectomy when controlling for patient-, disease- and procedure-related factors.

Laparoscopic surgery is well established in the modern management of colorectal disease. More recently, enhanced recovery after surgery (ERAS) protocols have been introduced to further promote accelerated discharge and faster recovery. However, not all patients are suitable for early discharge. The purpose of this study was to evaluate the early outcomes of patients undergoing such a regime to determine which peri-operative factors may predict safe accelerated discharge. Data were prospectively collected on consecutive patients undergoing laparoscopic colorectal surgery. All patients followed the institution's ERAS protocol and were discharged once specific criteria were fulfilled. Clinical characteristics and outcomes were compared between patients who were discharged before and after 72 h post-surgery. Thereafter, the peri-operative factors that were associated with delayed discharge were determined using a binary logistic model. Three hundred patients were included in the analysis. The most common operation was laparoscopic anterior resection (n = 123, 41%). Mean length of stay was 4.8 days (standard deviation 5.9), with 185 (62%) patients discharged within 72 h. Ten (3%) patients had a post-operative complication. Three independent predictors of delayed discharge were identified; BMI (OR 1.06, 95%CI 1.01-1.11), operation length (OR 0.99, 95%CI 0.98-0.99) and complications (OR 16.26, 95%CI 4.88-54.08). A combined approach of laparoscopic surgery and ERAS leads to reduced length of stay. This enables more than 60% of patients to be discharged within 72 h. Increased BMI, duration of operation and complications post-operatively independently predict a longer length of stay. Copyright © 2015 IJS Publishing Group Limited. Published by Elsevier Ltd.

All retractors for laparoscopic operations on the gallbladder or stomach apply an upward force to the under-surface of the liver or gallbladder, most requiring an additional skin incision. The LiVac laparoscopic liver retractor system (LiVac retractor) comprises a soft silicone ring attached to suction tubing and connected to a regulated source of suction. The suction tubing extends alongside existing ports. When placed between the liver and diaphragm, and suction applied, a vacuum is created within the ring, keeping these in apposition. Following successful proof-of-concept animal testing, a clinical study was conducted to evaluate the performance and safety of the retractor in patients. The study was a dual-centre, single-surgeon, open-label study and recruited ten patients scheduled to undergo routine upper abdominal laparoscopic surgery including cholecystectomy, primary gastric banding surgery or fundoplication. The study was conducted at two sites and was approved by the institutions' ethics committees. The primary objective of the study was to evaluate the performance of the LiVac retractor in patients undergoing upper abdominal single- or multi-port laparoscopic surgery. Performance was measured by the attainment of milestones for the retractor and accessory bevel, where used, and safety outcomes through the recording of adverse events, physical parameters, pain scales, blood tests and a post-operative liver ultrasound. The LiVac retractor achieved both primary and secondary performance and safety objectives in all patients. No serious adverse events and no device-related adverse events or device deficiencies were reported. The LiVac retractor achieved effective liver retraction without clinically significant trauma and has potential application in multi- or single-port laparoscopic upper abdominal surgery. As a separate incision is not required, the use of the LiVac retractor in multi-port surgery therefore reduces the number of incisions.

Laparoscopic surgery (LS) has proved superior compared to conventional surgery (CS) regarding morbidity, length of hospital stay, rate of wound infection and time until recovery. An improved preservation of the postoperative immune function is assumed to contribute to these benefits though the role of the local peritoneal immune response is still poorly understood. Our study investigates the peritoneal immune response subsequent to abdominal surgery and compares it between laparoscopic and conventional surgery to find an immunological explanation for the clinically proven benefits of LS. Wistar rats (N = 140) underwent laparoscopic cecum resection (LCR; N = 28), conventional cecum resection (CCR; N = 28), laparoscopic sham operation (LSO; N = 28), conventional sham operation (CSO; N = 28), or no surgical treatment (CTRL; N = 28). Postoperatively, peritoneal lavages were performed, leukocytes isolated and analyzed regarding immune function and phagocytosis activity. Immune function was inhibited postoperatively in animals undergoing LCR or CCR compared to CTRL reflected by a lower TNF-α (CTRL 3956.65 pg/ml, LCR 2018.48 pg/ml (p = 0.023), CCR 2793.78 pg/ml (n.s.)) and IL-6 secretion (CTRL 625.84 pg/ml, LCR 142.84 pg/ml (p = 0.009), CCR 169.53 pg/ml (p = 0.01)). Phagocytosis was not affected in rats undergoing any kind of surgery compared to CTRL. Neither cytokine secretion nor phagocytosis activity differed significantly between laparoscopic and conventional surgery. According to our findings the benefits associated with LS compared to CS cannot be explained by differences in the postoperative peritoneal innate immune response. Further studies are needed to elucidate the causes for a more favorable postoperative outcome in patients after LS compared to CS.

We investigated the effects of magnesium sulphate on blood coagulation profiles using rotational thromboelastometry in patients undergoing laparoscopic colorectal cancer surgery. Patients were randomly allocated to the magnesium group (n = 22) or control group (n = 22). The magnesium group received intravenous magnesium sulphate (50 mg.kg(-1) followed by a continuous infusion of 15 mg.kg(-1) .h(-1) ), whereas the control group received the same volume of isotonic saline. Mean (SD) postoperative serum magnesium levels were 1.60 (0.13) mmol.l(-1) in the magnesium group compared with 0.98 (0.06) mmol.l(-1) in the control group (p < 0.001). All maximum clot firmness values of ROTEM analysis were significantly lower on the third postoperative day in the magnesium group compared with the control group (p < 0.05). We conclude that ROTEM analysis demonstrated that intra-operative administration of intravenous magnesium sulphate reduces blood hypercoagulability in patients undergoing laparoscopic colorectal cancer surgery. © 2014 The Association of Anaesthetists of Great Britain and Ireland.

Cost in healthcare is an increasing and justifiable concern that impacts decisions about the introduction of new devices such as the da Vinci(®) surgical robot. Because equipment expenses represent only a portion of overall medical costs, we set out to make more specific cost comparisons between open and robot-assisted laparoscopic surgery. We performed a retrospective, observational, matched cohort study of 146 pediatric patients undergoing either open or robot-assisted laparoscopic urologic surgery from October 2004 to September 2009 at a single institution. Patients were matched based on surgery type, age, and fiscal year. Direct internal costs from the institution were used to compare the two surgery types across several procedures. Robot-assisted surgery direct costs were 11.9% (P=0.03) lower than open surgery. This cost difference was primarily because of the difference in hospital length of stay between patients undergoing open vs robot-assisted surgery (3.8 vs 1.6 days, P<0.001). Maintenance fees and equipment expenses were the primary contributors to robotic surgery costs, while open surgery costs were affected most by room and board expenses. When estimates of the indirect costs of robot purchase and maintenance were included, open surgery had a lower total cost. There were no differences in follow-up times or complication rates. Direct costs for robot-assisted surgery were significantly lower than equivalent open surgery. Factors reducing robot-assisted surgery costs included: A consistent and trained robotic surgery team, an extensive history of performing urologic robotic surgery, selection of patients for robotic surgery who otherwise would have had longer hospital stays after open surgery, and selection of procedures without a laparoscopic alternative. The high indirect costs of robot purchase and maintenance remain major factors, but could be overcome by high surgical volume and reduced prices as competitors enter the market.

Few multimodal strategies to minimize postoperative pain and improve recovery have been examined in morbidly obese patients undergoing laparoscopic bariatric surgery. The main objective of this study was to evaluate the effect of systemic intraoperative lidocaine on postoperative quality of recovery when compared to saline. The study was a prospective randomized, double-blinded placebo-controlled clinical trial. Subjects undergoing laparoscopic bariatric surgery were randomized to receive lidocaine (1.5 mg/kg bolus followed by a 2 mg/kg/h infusion until the end of the surgical procedure) or the same volume of saline. The primary outcome was the quality of recovery 40 questionnaire at 24 h after surgery. Fifty-one subjects were recruited and 50 completed the study. The global QoR-40 scores at 24 h were greater in the lidocaine group median (IQR) of 165 (151 to 170) compared to the saline group, median (IQR) of 146 (130 to 169), P = 0.01. Total 24 h opioid consumption was lower in the lidocaine group, median (IQR) of 26 (19 to 46) mg IV morphine equivalents compared to the saline group, median (IQR) of 36 (24 to 65) mg IV morphine equivalents, P = 0.03. Linear regression demonstrated an inverse relationship between the total 24 h opioid consumption (IV morphine equivalents) and 24 h postoperative quality of recovery (P < 0.0001). Systemic lidocaine improves postoperative quality of recovery in patients undergoing laparoscopic bariatric surgery. Patients who received lidocaine had a lower opioid consumption which translated to a better quality of recovery.

Although laparoscopic colorectal surgery decreases postoperative pain and facilitates a speedier recovery compared with laparotomy, postoperative pain at trocar insertion sites remains a clinical concern. The objective of this study was to assess the effects of a preoperative ultrasound-guided transversus abdominis plane (TAP) block on pain after laparoscopic surgery for colorectal cancer. In total, 58 patients scheduled to undergo laparoscopic surgery following a diagnosis of colorectal cancer were included in this study. The patients were randomized into TAP and control groups; the TAP group patients received a preoperative ultrasound-guided bilateral TAP block with 0.5 mL/kg of 0.25 % bupivacaine, while the control patients received the block with an equal amount of saline. Pain on coughing and at rest was assessed during postanesthetic recovery (PAR; 1 h after surgery) and on postoperative days (PODs) 1 (24 h), 2 (48 h), and 3 (72 h) by an investigator blinded to group allocations using the numeric rating scale (NRS). The primary outcome was pain on coughing on postoperative day (POD) 1. Fifty-five patients were included in the final analysis, including 28 in the TAP and 27 in the control groups. The pain intensity on coughing and at rest during PAR and on PODs 1, 2, and 3 showed no significant differences between groups. Furthermore, there was no significant difference in postoperative opioid consumption, sedation scores, nausea scores at the four time points, complication rates, and length of hospital stay between groups. In colorectal cancer patients undergoing laparoscopic colorectal surgery, a TAP block did not offer enough benefit for clinical efficacy in terms of postoperative pain or analgesic consumption.

The objective of this study was to compare the total hospital cost of laparoscopic (lap) and open colon surgery at a publicly funded academic institution. Patients undergoing elective laparoscopic or open colon surgery for all indications at the University Health Network, Toronto, Canada, from April 2004 to March 2009 were included. Patient demographic, operative, and outcome data were reviewed retrospectively. Hospital costs were determined from the Ontario Case Costing Initiative, adjusted for inflation, and compared using the Mann-Whitney U test. Linear regression was used to analyze the relationship between length of stay and total hospital cost. There were 391 elective colon resections (223 lap/168 open, 15.4 % conversion). There was no difference in median age, gender, or Charlson score. Body mass index was slightly higher for laparoscopic surgery (27.5/25.9 lap/open; p = 0.008), while the American Society of Anesthesiologists score was slightly higher for open surgery. Median operative time was greater for laparoscopic surgery (224/196 min, lap/open; p = 0.001). There was no difference in complication rates (21.6/22.5 % lap/open; p = 0.900), reoperations (5.8/6.5 % lap/open; p = 0.833) or 30-day readmissions (7.6/12.5 % lap/open; p = 0.122). Number of emergency room visits was greater with open surgery (12.6/20.8 % lap/open; p = 0.037). Operative cost was higher for laparoscopic surgery ($4,171.37/3,489.29 lap/open; p = 0.001), while total hospital cost was significantly reduced ($9,600.22/12,721.41 lap/open; p = 0.001). Median length of stay was shorter for laparoscopic surgery (5/7 days lap/open; p = 0.000), and this correlated directly with hospital cost. Laparoscopic colon surgery is associated with increased operative costs but significantly lower total hospital costs. The cost savings is related, in part, to reduced length of stay with laparoscopic surgery.

Laparoscopic colectomy for both benign and malignant disease, including inflammatory bowel disease (IBD), has recently been shown to have many advantages compared with open surgery. This study aimed to compare the effect of laparoscopic versus open subtotal colectomy (STC) for IBD on overall morbidity. A total of 99 patients undergoing STC for IBD at our institution from 2007 through 2011 were identified. Patients undergoing open STC were compared with patients undergoing laparoscopic STC. Outcomes included 30-day morbidity, conversion to laparotomy, intraoperative blood loss, operative time, admission time, late onset complications and 30-day mortality. Results are presented as median values. A total of 57 patients underwent open STC (Group 1) and 42 patients laparoscopic STC (Group 2). Group 1 comprised 26 males and 31 females, with a median age of 35 years and a body mass index (BMI) of 23.2 kg/m2. Group 2 comprised 18 males and 24 females, with a median age of 34 years and a BMI of 23.5 kg/m2. Group 2 had less morbidity (42.9% versus 75.4%, p < 0.002), reduced blood loss (100 ml versus 200 ml, p < 0.001), longer operative time (193.5 min. versus 128 min., p < 0.001), shorter length of hospital stay (six days versus 16 days, p < 0.001) than Group 1. One patient died (Group 1). There was no difference in late onset complications and no conversions to laparotomy in the laparoscopic group. Laparoscopic STC has a longer operative time, but improves short-term outcomes compared with open surgery. not relevant. not relevant.

The 2-port laparoscopic appendectomy technique (TLA) is between the conventional 3-port and single-port laparoscopic appendectomy surgeries. We compared postoperative pain and cosmetic results after TLA with conventional laparoscopic appendectomy (CLA) by a 3-port device. Patients undergoing TLA were matched with patients undergoing CLA between February 2015 and November 2015 at the same institution. Thirty-two patients underwent TLA with a needle grasper. The appendix was secured by a percutaneous organ-holding device (needle grasper), then removed through a puncture at McBurney's point. Another 38 patients underwent CLA. Patient demographics, operative details, and postoperative outcomes were collected and evaluated. One patient in the TLA group developed a wound infection and 1 patient in the CLA group developed a postoperative intra-abdominal abscess and 3 wound infections. There was no significant difference between the groups when comparing the length of hospital stay, time until oral intake, and other complications. The pain score in the first 12 hours after surgery was significanly higher in CLA group than the TLA group (P < 0.001). Operative time was significantly shorter in the CLA group compared to the TLA group (P < 0.001). TLA using a needle grasper was associated with a significantly lower pain score 12 hours after surgery, better cosmetic results, and lower cost, than the CLA 3-port procedure because of the fewer number of ports.

This study aims to assess the feasibility of acupuncture and a Pericardium 6 (PC6) wristband as an add-on intervention of antiemetic medication for the prevention of postoperative nausea and vomiting (PONV) in patients undergoing elective laparoscopic colorectal cancer resection. A total of 60 participants who are scheduled to undergo elective laparoscopic resection of colorectal cancer will be recruited. An enhanced recovery after surgery protocol using standardised antiemetic medication will be provided for all participants. Participants will be equally randomised into acupuncture plus PC6 wristband (Acupuncture), PC6 wristband alone (Wristband), or no acupuncture or wristband (Control) groups using computer-generated random numbers concealed in opaque, sealed, sequentially numbered envelopes. For the acupuncture combined with PC6 wristband group, the embedded auricular acupuncture technique for preoperative anxiolysis and up to three sessions of acupuncture treatments with manual and electrical stimulation within 48 hours after surgery will be provided by qualified Korean medicine doctors. The PC6 wristband will be applied in the Acupuncture and Wristband groups, beginning 1 hour before surgery and lasting 48 hours postoperatively. The primary outcome will be the number of participants who experience moderate or severe nausea, defined as nausea at least 4 out of 10 on a severity numeric rating scale or vomiting at 24 hours after surgery. Secondary outcomes, including symptom severity, participant global assessments and satisfaction, quality of life, physiological recovery, use of medication and length of hospital stay, will be assessed. Adverse events and postoperative complications will be measured for 1 month after surgery. All participants will provide written informed consent. The study has been approved by the institutional review board (IRB). This pilot trial will inform a full-scale randomised trial of acupuncture combined with PC6 stimulation for the prevention of PONV in patients undergoing elective laparoscopic colorectal cancer surgery.

Racial disparity in the treatment of colorectal cancer (CRC) has been cited as a potential cause for differences in mortality. This study compares the rates of laparoscopy according to race, insurance status, geographic location, and hospital size. The 2009 Healthcare Cost and Utilization Project: Nationwide Inpatient Sample (HCUP-NIS) database was queried to identify patients with the diagnosis of CRC by the International Classification of Diseases, Ninth Revision (ICD-9) codes. Multivariate logistic regression was performed to look at age, gender, insurance coverage, academic versus nonacademic affiliated institutions, rural versus urban settings, location, and proportional differences in laparoscopic procedures according to race. A total of 14,502 patients were identified; 4,691 (32.35 %) underwent laparoscopic colorectal procedures and 9,811 (67.65 %) underwent open procedures. The proportion of laparoscopic procedures did not differ significantly by race: Caucasian 32.4 %, African-American 30.04 %, Hispanic 33.99 %, and Asian-Pacific Islander 35.12 (P = 0.08). Among Caucasian and African-American patients, those covered by private insurers were more likely to undergo laparoscopic procedures compared to other insurance types (P ≤ 0.001). The odds of receiving laparoscopic procedure at teaching hospitals was 1.39 times greater than in nonteaching hospitals (95 % confidence interval [CI] 1.29-1.48) and did not differ across race groups. Patients in urban hospitals demonstrated higher odds of laparoscopic surgery (2.24, 95 % CI 1.96-2.56) than in rural hospitals; this relationship was consistent within races. The odds of undergoing laparoscopic surgeries was lowest in the Midwest region (0.89, 95 % CI 0.81-0.97) but higher in the Southern region (1.14, 95 % CI 1.06-1.22) compared with the other regions. Nearly one-third of all CRC surgeries are laparoscopic. Race does not appear to play a significant role in the selection of a laparoscopic CRC operation. However, there are significant differences in the selection of laparoscopy for CRC patients based on insurance status, geographic location, and hospital type.

Laparoscopic Surgery Using Spinal Anesthesia

Background: Laparoscopic abdominal surgery is conventionally done under general anesthesia. Spinal anesthesia is usually preferred in patients where general anesthesia is contraindicated. We present our experience using spinal anesthesia as the first choice for laparoscopic surgery for over 11 years with the contention that it is a good alterative to anesthesia. Methods: Spinal anesthesia was used in 4645 patients over the last 11 years. Laparoscopic cholecystectomy was performed in 2992, and the remaining patients underwent other laparoscopic surgeries. There was no modification in the technique, and the intraabdominal pressure was kept at 8mm Hg to 10mm Hg. Sedation was given if required, and conversion to general anesthesia was done in patients not responding to sedation or with failure of spinal anesthesia. Results were compared with those of 421 patients undergoing laparoscopic surgery while under general anesthesia. Results: Twenty-four (0.01%) patients required conversion to general anesthesia. Hypotension requiring support was recorded in 846 (18.21%) patients, and 571(12.29%) experienced neck or shoulder pain, or both. Postoperatively, 2.09% (97) of patients had vomiting compared to 29.22% (123 patients) of patients who were administered general anesthesia. Injectable diclofenac was required in 35.59% (1672) for abdominal pain within 2 hours postoperatively, and oral analgesic was required in 2936 (63.21%) patients within the first 24 hours. However, 90.02% of patients operated on while under general anesthesia required injectable analgesics in the immediate postoperative period. Postural headache persisting for an average of 2.6 days was seen in 255 (5.4%) patients postoperatively. Average time to discharge was 2.3 days. Karnofsky Performance Status Scale showed a 98.6% satisfaction level in patients. Conclusions: Laparoscopic surgery done with the patient under spinal anesthesia has several advantages over laparoscopic surgery done with the patient under general anesthesia. PMID:18435884

Ureteral injury during laparoscopic surgery is rare, but when it occurs, it can be a serious problem. Near-infrared fluorescence (NIRF) with methylene blue (MB) administration is a promising technique for easier and potentially earlier intraoperative visualization of the ureter. Aim of this prospective study was to assess the feasibility of NIRF imaging of the ureter during laparoscopic colorectal surgery, using MB. Patients undergoing laparoscopic colorectal surgery were included and received intravenous injection of MB preoperatively. The ureter was visualized using a laparoscope, which offered both conventional and fluorescence imaging. Intraoperative recognition of the ureter was registered. The precision of ureter distinction with MB imaging was compared to the conventional laparoscopic view. Ten patients were included. All procedures were initially performed using a laparoscopic approach. Dose per injection ranged between 0.125 mg/kg and 1.0 mg/kg bodyweight. There were no adverse effects attributable to MB administration. The ureter was successfully detected in five patients, with highest contrast between ureter and surrounding tissue at an administered dose of 0.75-1.0 mg/kg. The fluorescent signal was only picked up after the ureter was already visible in the conventional white light mode. Ureteral fluorescence imaging using MB proved to be safe and feasible. However, the present technique does not provide practical advantage over conventional laparoscopic imaging for identification of the ureter during laparoscopic colorectal surgery. Future research is necessary to explore more extensive dose finding, alternative fluorescent dyes, or improvement of the imaging system to make this application clinically beneficial.

Clinical treatment guidelines have suggested that laparoscopic hernia repair should be the preferred approach in both men and women with bilateral or recurrent elective groin hernias. Anecdotal evidence suggests, however, that women are less likely to undergo a laparoscopic repair than men, and therefore, we aimed to delineate if these disparities persisted after controlling for patient factors and comorbidities. The American College of Surgeons National Surgical Quality Improvement Project data were abstracted for all elective groin hernia repairs between 2005 and 2014. Univariate analysis was used to compare rates of laparoscopic surgery between men and women. Multivariable analysis was performed, controlling for patient demographics, preoperative comorbidities, and year of surgery. Over the 10-y period, 141,490 patients underwent elective groin hernia repair, of which 13,325 were women (9.4%). The rate of general anesthesia utilization was high in both men (81.3%) and women (77.2%) with 75.1% of open repairs being performed under general anesthesia. Overall, 20.2% of women underwent laparoscopic repair compared with 28.0% of men (P < 0.01). Women tended to be older, had a lesser body mass index, and slightly greater American Anesthesia Association (all P < 0.05). On multivariable regression, women had decreased odds of undergoing a laparoscopic approach compared with men (odds ratio: 0.70; 95% confidence interval, 0.67-0.73, P < 0.01). In the elective setting, women were less likely to undergo laparoscopic repair of groin hernias than men. Although we are unable to ascertain underlying causes for these gender disparities, these data suggest that there remains a disparity in the management of groin hernias in women.

Inadequate perioperative fluid therapy impairs gastrointestinal function. Studies primarily evaluating the impact of goal-directed fluid therapy on primary postoperative ileus are missing. The objective of this study was to determine whether goal-directed fluid therapy reduces the incidence of primary postoperative ileus after laparoscopic colorectal surgery within an Enhanced Recovery After Surgery program. Randomized patient and assessor-blind controlled trial conducted in adult patients undergoing laparoscopic colorectal surgery within an Enhanced Recovery After Surgery program. Patients were assigned randomly to receive intraoperative goal-directed fluid therapy (goal-directed fluid therapy group) or fluid therapy based on traditional principles (control group). Primary postoperative ileus was the primary outcome. One hundred twenty-eight patients were included and analyzed (goal-directed fluid therapy group: n = 64; control group: n = 64). The incidence of primary postoperative ileus was 22% in the goal-directed fluid therapy and 22% in the control group (relative risk, 1; 95% CI, 0.5 to 1.9; P = 1.00). Intraoperatively, patients in the goal-directed fluid therapy group received less intravenous fluids (mainly less crystalloids) but a greater volume of colloids. The increase of stroke volume and cardiac output was more pronounced and sustained in the goal-directed fluid therapy group. Length of hospital stay, 30-day postoperative morbidity, and mortality were not different. Intraoperative goal-directed fluid therapy compared with fluid therapy based on traditional principles does not reduce primary postoperative ileus in patients undergoing laparoscopic colorectal surgery in the context of an Enhanced Recovery After Surgery program. Its previously demonstrated benefits might have been offset by advancements in perioperative care.

Study Design The Surgical Care and Outcomes Assessment Program (SCOAP) is a quality improvement (QI) benchmarking initiative in the Northwest using medical record-based data. We evaluated the use of laparoscopy and a composite of adverse events (CAE; death or clinical reintervention) for patients undergoing elective colorectal surgery at 48 hospitals from 4th quarter of 2005 through 4th quarter of 2010. Results Of the 9,705 patients undergoing elective colorectal surgeries (mean age 60.6 ± 15.6 (SD) yrs; 55.2% women), 38.0% were performed laparoscopically (17.8% laparoscopic procedures converted to open). The use of laparoscopic procedures increased from 23.3% in 2005 quarter 4 to 41.6% in 2010 quarter 4 (trend over study period, p<0.001). After adjustment (age, sex, albumin levels, diabetes, body mass index, comorbidity index, cancer diagnosis, year, hospital bed size and urban vs. rural location), the risk of transfusions [odds ratio (OR) 0.52, 95% CI 0.39–0.7], wound infections (OR 0.45, 95% CI 0.34–0.61), and CAEs (OR 0.58; 95%CI 0.43–0.79) were all significantly lower with laparoscopy. Within those hospitals that had been in SCOAP since 2006, hospitals where laparoscopy was most commonly used also had a significant increase in the volume of all types of colon surgery (202 cases per hospital in 2010 from 112 cases per hospital in 2006, 80.4% increase), and in particular the number of resections for non-cancer diagnoses and right sided pathology. Conclusions The use of laparoscopic colorectal resection increased in the Northwest. Increased adoption of laparoscopic colectomies was associated with greater use of all types of colorectal surgery.

Robotic surgery is a rapidly growing area in surgery. In an era of emphasis on cost reduction, the question becomes how do you train residents in robotic surgery? The aim of this study was to determine if there was a difference in operative time and complications when comparing general surgery residents learning robotic cholecystectomies to those learning standard laparoscopic cholecystectomies. A retrospective analysis of adult patients undergoing robotic and laparoscopic cholecystectomy by surgical residents between March 2013 and February 2014 was conducted. Demographic data, operative factors, length of stay (LOS), and complications were examined. Univariate and multivariate analyses were performed. The significance was set at p < 0.05. A total of 58 patients were included in the study (18 in the robotic cholecystectomy group and 40 in the laparoscopic group). Age, diagnosis, and American Society of Anesthesiologists score were not significantly different between groups. There was only 1 complication in the standard laparoscopic group in which a patient had to be taken back to surgery because of an incarcerated port site. LOS was significantly higher in the standard laparoscopic group (mean = 2.28) than in the robotic group (mean = 0.56; p < 0.0001). Operating room (OR) time was not statistically different between the standard laparoscopic group (mean = 90.98 minutes) and the robotic group (mean = 97.00 minutes; p = 0.4455). When intraoperative cholangiogram was evaluated, OR time was shorter in the robotic group. Robotic training in general surgery residency does not amount to extra OR time. LOS in our study was significantly longer in the standard laparoscopic group. Copyright © 2015 Association of Program Directors in Surgery. Published by Elsevier Inc. All rights reserved.

Population-based studies evaluating outcomes of different approaches for rectal cancer are scarce. We conducted a retrospective cohort study using the Nationwide Inpatient Sample database between 2008 and 2012. We compared the outcomes and costs among rectal cancer patients undergoing robotic, laparoscopic, or open surgeries using propensity scores for adjusted and matched analysis. We identified 194 957 rectal cancer patients. Over the 5-year period, the annual admission number decreased by 13.9%, the in-hospital mortality rate decreased by 32.2%, while the total hospitalization cost increased by 13.6%. Compared with laparoscopic surgery, robotic surgery had significantly lower length of stay (LOS) (OR 0.69, 95%CI 0.57-0.84), comparable wound complications (OR 1.08, 95%CI 0.70-1.65) and higher cost (OR 1.42, 95%CI 1.13-1.79), while open surgery had significantly longer LOS (OR 1.38, 95%CI 1.19-1.59), more wound complications (OR 1.49, 95%CI 1.08-1.79), and comparable cost (OR 0.92, 95%CI 0.79-1.07). There were no difference in in-hospital mortality among three approaches. Laparoscopic surgery was associated with better outcomes than open surgery. Robotic surgery was associated with higher cost, but no advantage over laparoscopic surgery in terms of mortality and complications. Studies on cost-effectiveness of robotic surgery may be warranted. © 2017 Wiley Periodicals, Inc.

Different fluid regimens are used in the clinical management of perioperative fluid therapy, but there still is the argument about which fluid regimen is better for patients. This study was mainly designed to compare different fluid regimens on postoperative pain and residual gas in patients undergoing laparoscopic cholecystectomy. A total of 100 patients were equally randomized to receive restrictive fluid infusion (n=50) with lactated Ringer (LR) solution 5 mL/kg/h or liberal fluid infusion (n=50), with 30 mL/kg/h lactated Ringer solution. Postoperative pain was evaluated at 1, 6, and 24 hours after surgery using a visual analog scale (VAS). Postoperative subdiaphragmatic residual gas was monitored by x-ray at 24 hours after surgery. Patients in the restrictive group had significantly higher VAS pain scores at 6 hours after surgery than those in the liberal group (P=0.009). The incidence of subdiaphragmatic residual gas in the restrictive group was higher than in the liberal group (P=0.045). Patients who had residual gas had higher VAS pain scores than those with no residual gas in the restrictive group at 6 hours after surgery (P=0.02). Patients undergoing laparoscopic cholecystectomy with restrictive fluid therapy may suffer more severe postoperative pain than those receiving liberal fluid therapy. It suggests that the higher incidence of subdiaphragmatic residual gas may have occurred with restrictive fluid therapy.

Posterior transversus abdominis plane blocks have been reported to be an effective method of providing analgesia after lower abdominal surgery. We compared the efficacy of a novel technique of providing continuous transversus abdominis plane analgesia with epidural analgesia in patients on an enhanced recovery programme following laparoscopic colorectal surgery. A non-inferiority comparison was used. Adult patients undergoing elective laparoscopic colorectal surgery were randomly assigned to receive continuous transversus abdominis plane analgesia (n = 35) vs epidural analgesia (n = 35), in addition to a postoperative analgesic regimen comprising regular paracetamol, regular diclofenac and tramadol as required. Sixty-one patients completed the study. The transversus group received four-quadrant transversus abdominis plane blocks and bilateral posterior transversus abdominis plane catheters that were infused with levobupivacaine 0.25% for 48 h. The epidural group received an infusion of bupivacaine and fentanyl. The primary outcome measure was visual analogue scale pain score on coughing at 24 h after surgery. We found no significant difference in median (IQR [range]) visual analogue scores during coughing at 24 h between the transversus group 2.5 (1.0-3.0 [0-5.5]) and the epidural group 2.5 (1.0-5.0 [0-6.0]). The one-sided 97.5% CI was a 0.0 (∞-1.0) difference in means, establishing non-inferiority. There were no significant differences between the groups for tramadol consumption. Success rate was 28/30 (93%) in the transversus group vs 27/31 (87%) in the epidural group. Continuous transversus abdominis plane infusion was non-inferior to epidural infusion in providing analgesia after laparoscopic colorectal surgery. © 2013 The Association of Anaesthetists of Great Britain and Ireland.

The journey from conventional "open" operations to truly "minimally invasive" operations naturally includes progression from operations involving multiple trocars and multiple incisions to operations involving access through the umbilicus alone. Laparoscopic operations through the umbilicus alone, laparoendoscopic single site surgery (LESS), offer improved cosmesis and hopes for less pain and improved recovery. This study was undertaken to evaluate our initial experience with LESS cholecystectomy and to compare our initial experience to concurrent outcomes with more conventional multiport, multi-incision laparoscopic cholecystectomy. All patients referred for cholecystectomy over a 6-month period were offered LESS. Outcomes, including blood loss, operative time, complications, and length of stay were recorded. Outcomes with our first LESS cholecystectomies were compared to an uncontrolled group of concurrent patients undergoing multiport, multi-incision laparoscopic cholecystectomy at the same hospital by the same surgeon. Twenty-nine patients of median age 50 years undergoing LESS cholecystectomy from November 2007 until May 2008 were compared to 29* patients, median age 48 years, undergoing standard multiport, multiple-incision laparoscopic cholecystectomy over the same time period. Median operative time for patients undergoing LESS cholecystectomy was 72 min and was not different from that of patients undergoing multiport, multi-incision laparoscopic cholecystectomy (p = 0.81). Median length of hospital stay was 1.0 day for patients undergoing LESS cholecystectomy and was not different from patients undergoing standard laparoscopic cholecystectomy (p = 0.46). Operative estimated blood loss was less than 100 cc for all patients. No patients undergoing attempted LESS cholecystectomy had conversions to "open" operations; two patients had an additional trocar(s) placed distant from the umbilicus to aid in exposure. Three patients undergoing LESS cholecystectomy had complications: two were troubled by pain control and another had urinary retention. LESS cholecystectomy is a safe and effective alternative to standard laparoscopic cholecystectomy. It can be undertaken without the expense of added operative time and provides patients with minimal, if any, apparent scarring. We believe LESS cholecystectomy will be driven by consumer demand, and therefore, laparoscopic surgeons will need to become proficient with LESS procedures.

The best training method in laparoscopic surgery has not been defined. We evaluated the efficacy of laparoscopic skills acquisition in a short-term focused program. Two hundred fifty-six participants undergoing training on a phantom model were divided into 2 groups. Group 1 had no exposure and group 2 had performed a few laparoscopic surgeries. Acquisition of laparoscopic skills was assessed by operation time and the modified Global Operative Assessment of Laparoscopic Skills (GOALS) scale. A questionnaire was sent to the participants after 3 to 6 months for assessment of impact of training. There was a statistically significant improvement in the assessed parameters and in the mean score of all 5 domains of GOALS. The participants in group 2 performed better than those in group 1 in the first case. The difference between both the groups disappeared after the training. Participants who responded to the questionnaire felt that training helped them in improving their performance in the operation theater.

This study examined effects of health maintenance organization (HMO) penetration, hospital competition, and patient severity on the uptake of laparoscopic colectomy and its price relative to open surgery for colon cancer. The MarketScan Database (data from 2002-2007) was used to identify admissions for privately insured colorectal cancer patients undergoing laparoscopic or open partial colectomy (n = 1035 and n = 6389, respectively). Patient and health plan characteristics were retrieved from these data; HMO market penetration rates and an index of hospital market concentration, the Herfindahl-Hirschman index (HHI), were derived from national databases. Logistic and logarithmic regressions were used to examine the odds of having laparoscopic colectomy, effect of covariates on colectomy prices, and the differential price of laparoscopy. Adoption of laparoscopy was highly sensitive to market forces, with a 10% increase in HMO penetration leading to a 10.9% increase in the likelihood of undergoing laparoscopic colectomy (adjusted odds ratio = 1.109; 95% confidence interval [CI] = 1.062, 1.158) and a 10% increase in HHI resulting in 6.6% lower likelihood (adjusted odds ratio = 0.936; 95% CI = 0.880, 0.996). Price models indicated that the price of laparoscopy was 7.6% lower than that of open surgery (transformed coefficient = 0.927; 95% CI = 0.895, 0.960). A 10% increase in HMO penetration was associated with 1.6% lower price (transformed coefficient = 0.985; 95% CI = 0.977, 0.992), whereas a 10% increase in HHI was associated with 1.6% higher price (transformed coefficient = 1.016; 95% CI = 1.006, 1.027; P < .001 for all comparisons). Laparoscopy was significantly associated with lower hospital prices. Moreover, laparoscopic surgery may result in cost savings, while market pressures contribute to its adoption.

This study was designed to compare the operative and short-term postoperative outcomes of the robotic and laparoscopic staplers in patients undergoing rectal surgery for cancer. Between December 2014 and April 2017, patients consecutively undergoing robotic rectal surgery for cancer were included in this study. Patients were grouped into two according to the type of staplers for rectal transection [Robotic (45-mm) versus Laparoscopic (60-mm) linear staplers]. Patient demographics, pathologic data, perioperative outcomes, and short-term results were compared. One hundred seven patients met our inclusion criteria. The number of male patients were higher in robotic stapler group than in the laparoscopic stapler group (55% versus 76%, P = .03). Age (59 versus 63 years, P = .40), body mass index (27 versus 27 kg/m 2 , P = .60), American Society of Anesthesiologists score (2 versus 2, P = .20), number of prior abdominal operations (31% versus 20%, P = .22) and number of patients having neoadjuvant chemoradiotherapy (34% versus 36%, P = .86) were comparable between the groups. The numbers of cartridges used were similar regardless of the type of staplers (2 versus 2, P = .58). The overall complication was similar between the groups (24% versus 31%, P = .32). Leak rates were 5% (n = 2) and 3% (n = 2) in the robotic and laparoscopic stapler groups, respectively (p = 1). There was no mortality. This is the first study evaluating the role of robotic stapler specifically for rectal transection in comparative manner. The use of robotic stapler for rectal transection was safe and feasible in rectal surgery for cancer.

Partial fundoplications provide similar reflux control with fewer post-fundoplication symptoms compared with Nissen fundoplication for gastro-oesophageal reflux disease (GORD). The best choice of procedure for partial fundoplication remains unclear. The aim of this study was to compare the outcome of two different types of partial fundoplication for GORD. A double-blind RCT was conducted between 2012 and 2015 in two hospitals specializing in antireflux surgery. Patients were randomized to undergo either a laparoscopic 270° posterior fundoplication (Toupet) or a laparoscopic 180° anterior fundoplication. The primary outcome was postoperative dysphagia at 12 months, measured by the Dakkak score. Subjective outcome was analysed at 1, 3, 6 and 12 months after surgery. Objective reflux control was assessed before and 6 months after surgery. Ninety-four patients were randomized to laparoscopic Toupet or laparoscopic 180° anterior fundoplication (47 in each group). At 12 months, 85 patients (90 per cent) were available for follow-up. Objective scores were available for 76 (81 per cent). Postoperative Dakkak dysphagia score at 12 months was similar in the two groups (mean 5·9 for Toupet versus 6·4 for anterior fundoplication; P = 0·773). Subjective outcome at 12 months demonstrated no significant differences in control of reflux or post-fundoplication symptoms. Overall satisfaction and willingness to undergo surgery did not differ between the groups. Postoperative endoscopy and 24-h pH monitoring showed no significant differences in mean oesophageal acid exposure time or recurrent pathological oesophageal acid exposure. Both types of partial fundoplication provided similar control of GORD at 12 months, with no difference in post-fundoplication symptoms.

Patient and health plan characteristics were retrieved from these data; HMO market penetration rates and an index of hospital market concentration, Herfindahl-Hirschman Index (HHI), were derived from national databases. Logistic and logarithmic regressions were used to examine the odds of having laparoscopic colectomy, effect of covariates on colectomy prices, and the differential price of laparoscopy. Results Adoption of laparoscopy was highly sensitive to market forces, with a 10% increase in HMO penetration leading to a 10.3% increase in the likelihood of undergoing laparoscopic colectomy (Adjusted Odds Ratio (AOR): 1.109, 95% Confidence Interval: 1.062, 1.158), and a 10% increase in HHI resulting in 6.6% lower likelihood (AOR: 0.936 (0.880, 0.996)). Price models indicated that the price of laparoscopy was 7.6% lower than for open surgery (transformed coefficient (Coeff): 0.927 (0.895, 0.960)). A 10% increase in HMO penetration was associated with 1.6% lower price (Coeff: 0.985 (0.977, 0.992)), while a 10% increase in HHI was associated with 1.6% higher price (Coeff: 1.016 (1.006, 1.027), p < 0.001 for all comparisons). Conclusions Laparoscopy was significantly associated with lower hospital prices. Moreover, Impact Laparoscopic surgery may result in cost savings, while market pressures contribute to its adoption.

The Roux-en-Y gastric bypass procedure (RYGBP) is in many countries the gold standard for obtaining long-lasting weight reduction and improvement of obesity-related comorbidities. However, performing this operation by standard laparoscopic techniques requires important surgical skills because of the anastomoses involved. The da Vinci surgical robot system with its enhanced degrees of freedom in motion and three-dimensional vision is designed to overcome the difficulties encountered in traditional laparoscopic surgery with suturing and delicate tissue handling. For this study, 45 patients (9 men) with a mean body mass index (BMI) of 44.2 (range, 35.1-55.4) underwent RYGBP with the aid of the da Vinci robot system. They were compared with 45 consecutive patients with a mean BMI of 43.9 (range, 35.1-56.2) who underwent a laparoscopic RYGBP by the same surgeon during the same period. Overall, the total operating time was shorter for the laparoscopic cases (127 vs 212 min; p < 0.05). However, the last 10 robotic cases were performed in the same time span as the laparoscopic cases (136 vs 127 min). The total robotic setup time remained constant at about 30 min. There were no differences in postoperative complications between the two groups in terms of anastomotic leakage or stenosis. In the robotic group, more conversions to open surgery were noted. Early in the study, four patients (9%) had to undergo conversion to standard laparoscopic techniques due to inadequate setup of the robotic arms. Five patients (11%), however, had to undergo conversion to open surgery because of intestinal laceration during manipulation of the intestines with the robotic instruments. The costs were higher for robotic surgery than for standard laparoscopic RYGBP, mainly because of the extra equipment used, such as ultrasonic devices. The RYGBP procedure can be performed safely with the da Vinci robot after a learning curve of about 35 cases. At this writing, however, it is not clear whether the da Vinci system offers a real advantage over standard laparoscopic techniques.

We retrospectively examined the effect of remifentanil on urine output during gynecological laparoscopic surgery under general anesthesia performed from April 2006 to July 2007. Forty six patients undergoing gynecological laparoscopic surgery under general anesthesia were divided into 2 groups. In group C (n=23), anesthesia was performed using sevoflurane and/or propofol with intermittent fentanyl. In group R (n=23), remifentanil was additionally used with the method of group C. Patient's demography was not different between the two groups. Intraoperative conditions were compatible in both groups. In group R, total dose of fentanyl is significantly lower than group C. BP and HR measured at 20 min after pneumoperitoneum were significantly lower in group R. Intraoperative urine output was significantly greater in group R than group C. A decrease in urine output is commonly seen particularly in laparoscopic surgery. Increased stress hormonal responses due to pneumoperitoneum have been explained as one of the causes of this phenomenon. Remifentanil has been reported to maintain urine output as well as to blunt hormonal responses in CABG surgery. Although we did not measure hormonal responses in the present study, increased urine output could be attributed to decreased catecholamine levels by remifentanil.

Older people undergoing any surgery have a higher incidence of morbidity and mortality, resulting from a decline in physiological reserves, associated comorbidities, polypharmacy, cognitive dysfunction, and frailty. Most of the clinical trials comparing regional versus general anesthesia in elderly have failed to establish superiority of any single technique. However, the ideal approach in elderly is to be least invasive, thus minimizing alterations in homeostasis. The goal of anesthetic management in laparoscopic procedures includes management of pneumoperitoneum, achieving an adequate level of sensory blockade without any respiratory compromise, management of shoulder tip pain, provision of adequate postoperative pain relief, and early ambulation. Regional anesthesia fulfills all the aforementioned criteria and aids in quick recovery and thus has been suggested to be a suitable alternative to general anesthesia for laparoscopic surgeries, particularly in patients who are at high risk while under general anesthesia or for patients unwilling to undergo general anesthesia. In conclusion, we report results of successful management with thoracic combined spinal epidural for laparoscopic cholecystectomy of a geriatric patient with ischemic heart disease with chronic obstructive pulmonary disease and renal insufficiency.

Urological and sexual dysfunction are recognised risks of rectal cancer surgery; however, there is limited evidence regarding urogenital function comparing robotic to laparoscopic techniques. The aim of this study was to assess the urogenital functional outcomes of patients undergoing laparoscopic and robotic rectal cancer surgery. Urological and sexual functions were assessed using gender-specific validated standardised questionnaires. Questionnaires were sent a minimum of 6 months after surgery, and patients were asked to report their urogenital function pre- and post-operatively, allowing changes in urogenital function to be identified. Questionnaires were sent to 158 patients (89 laparoscopy, 69 robotic) of whom 126 (80 %) responded. Seventy-eight (49 male, 29 female) of the responders underwent laparoscopic and 48 (35 male, 13 female) robotic surgery. Male patients in the robotic group deteriorated less across all components of sexual function and in five components of urological function. Composite male urological and sexual function score changes from baseline were better in the robotic cohort (p < 0.001). In females, there was no difference between the two groups in any of the components of urological or sexual function. However, composite female urological function score change from baseline was better in the robotic group (p = 0.003). Robotic rectal cancer surgery might offer better post-operative urological and sexual outcomes compared to laparoscopic surgery in male patients and better urological outcomes in females. Larger scale, prospective randomised control studies including urodynamic assessment of urogenital function are required to validate these results.

Different types of single-incision laparoscopic surgery (SILS) have become increasingly popular. Although SILS is technically even more challenging than conventional laparoscopy, published data of first clinical series seem to demonstrate the feasibility of these approaches. Various attempts have been made to overcome restrictions due to loss of triangulation in SILS by specially designed SILS-specific instruments. This study involving novices in a dry lab compared task performances between conventional laparoscopic surgery (CLS) and single-port laparoscopic surgery (SPLS) using newly designed pre-bent instruments. In this study, 90 medical students without previous experience in laparoscopic techniques were randomly assigned to undergo one of three procedures: CLS, SPLS using two pre-bent instruments (SPLS-pp), or SPLS using one pre-bent and one straight laparoscopic instrument (SPLS-ps). In the dry lab, the participants performed four typical laparoscopic tasks of increasing difficulty. Evaluation included performance times or number of completed tasks within a given time frame. All performances were videotaped and evaluated for unsuccessful attempts and unwanted interactions of instruments. Using subjective questionnaires, the participants rated difficulties with two-dimensional vision and coordination of instruments. Task performances were significantly better in the CLS group than in either SPLS group. The SPLS-ps group showed a tendency toward better performances than the SPLS-pp group, but the difference was not significant. Video sequences and participants` questionnaires showed instrument interaction as the major problem in the single-incision surgery groups. Although SILS is feasible, as shown in clinical series published by laparoscopically experienced experts, SILS techniques are demanding due to restrictions that come with the loss of triangulation. These can be compensated only partially by currently available SILS-designed instruments. The future of SILS depends on further improvements in the available equipment or the development of new approaches such as needlescopically assisted or robotically assisted procedures.

The aim of this study was to describe the feasibility and outcome of laparoscopic risk-reducing salpingo-oophorectomy (RRSO) in patients with a history of breast cancer who previously had undergone a transverse rectus abdominus myocutaneous (TRAM) flap reconstruction. We performed a retrospective review of patients with a history of breast cancer who had undergone laparoscopic RRSO between February 1995 and April 2002. Patients who had undergone TRAM flap reconstructive surgery were compared with patients who had undergone laparoscopic RRSO without prior reconstructive surgery. We identified 102 patients with a history of breast cancer who were candidates for a laparoscopic RRSO during the study period. One hundred one of these patients underwent the procedure, including 10 patients with a history of TRAM flap breast reconstructive surgery. One patient did not undergo the procedure because she was noted to be hypotensive prior to the procedure from her bowel preparation. There were no differences between the groups with or without prior history of TRAM flap reconstruction with respect to body mass index, prior abdominal surgery, menopausal status, or preoperative ultrasound characteristics. Operatively, there was no difference between the groups with respect to estimated blood loss, hospital stay, and intraoperative and postoperative complication rates. The only noted difference between the two groups was the estimated operating time (TRAM group, 91 min; non-TRAM group, 70 min [P<0.01]). Laparoscopic RRSO is safe and feasible in patients who have undergone a prior TRAM flap reconstruction.

Accurate identification of the location of colorectal lesions is crucial during laparoscopic surgery. Endoscopic marking has been used as an effective preoperative marker for tumor identification. We investigated the feasibility and safety of an imaging method using near-infrared, light-emitting, diode-activated indocyanine green fluorescence in colorectal laparoscopic surgery. This was a single-institution, prospective study. This study was conducted in a tertiary referral hospital. We enrolled 24 patients who underwent laparoscopic surgery. Indocyanine green and India ink were injected into the same patients undergoing preoperative colonoscopy for colon cancer. During subsequent laparoscopic resection of colorectal tumors, the colon was first observed with white light. Then, indocyanine green was activated with a light-emitting diode at 760 nm as the light source. Near-infrared-induced fluorescence showed tumor location clearly and accurately in all 24 of the patients. All of the patients who underwent laparoscopic surgery after marking had positive indocyanine green staining at the time of surgery. Perioperative complications attributed to dye use were not observed. This study is limited by the cost of indocyanine green detection, the timing of the colonoscopy and tattooing in relation to the operation and identification with indocyanine green, and the small size of the series. These data suggest that our novel method for colonic marking with fluorescence imaging of near-infrared, light-emitting, diode-activated indocyanine green is feasible and safe. This method is useful, has no adverse effects, and can be used for perioperative identification of tumor location. Near-infrared, light-emitting, diode-activated indocyanine green has potential use as a colonic marking agent.

Patients undergoing general anesthesia for laparoscopic cholecystectomy are at high risk for postoperative nausea and vomiting (PONV). This study compared ramosetron and ondansetron in terms of efficacy for PONV prevention after laparoscopic cholecystectomy. For this study, 120 patients scheduled to undergo laparoscopic cholecystectomy were randomized (in double-blind fashion) to receive 4 mg of ondansetron (group O4, n = 40), 8 mg of ondansetron (group O8, n = 40), or 0.3 mg of ramosetron (group R, n = 40) intravenously after surgery. Postoperative nausea, retching, vomiting, pain, and side effects were assessed at 2 h, 24 h, and 48 h after surgery. No statistical differences were observed among the three groups with regard to patient characteristics and information on surgery and anesthesia. The ratio of complete response (no PONV for 2 h) was higher for groups O8 and R than for group O4 as follows: 80% (n = 32) for groups O8 and R versus 58% (n = 23) for group O4 during the first postoperative 2 h (p = 0.04), 90% (n = 36) for groups O8 and R versus 76% (n = 30) for group O4 over 24 h (2-24 h) (p = 0.09), and 98% (n = 38) for groups O4 and O8 versus 100% (n = 40) for group R over the next 24 h (24-48 h) after surgery (p = 0.36). During the first 2 h after surgery, rescue antiemetics were used for significantly fewer patients in groups O8 and R (20%) than in group O4 (42.5%) (p = 0.04). Postoperative pain and the use of rescue analgesics were comparable among the groups. There was no clinically serious adverse event due to the study drugs. Ramosetron 0.3 mg and ondansetron 8 mg are more effective than ondansetron 4 mg for the prevention of PONV (2 h). Ramosetron 0.3 mg is as effective as ondansetron 8 mg for the prophylaxis of PONV after laparoscopic cholecystectomy.

Laparoscopic cholecystectomy became the standard surgery for gallstone disease because of causing less postoperative pain, respiratory compromise and early ambulation. This study was designed to compare spinal anesthesia, (segmental thoracic or conventional lumbar) vs the gold standard general anesthesia as three anesthetic techniques for healthy patients scheduled for elective laparoscopic cholecystectomy, evaluating intraoperative parameters, postoperative recovery and analgesia, complications as well as patient and surgeon satisfaction. A total of 90 patients undergoing elective laparoscopic cholecystectomy, between January 2010 and May 2011, were randomized into three equal groups to undergo laparoscopic cholecystectomy with low-pressure CO2 pneumoperitoneum under segmental thoracic (TSA group) or conventional lumbar (LSA group) spinal anesthesia or general anesthesia (GA group). To achieve a T3 sensory level we used (hyperbaric bupivacaine 15 mg, and fentanyl 25 mg at L2/L3) for LSAgroup, and (hyperbaric bupivacaine 7.5 mg, and fentanyl 25 mg at T10/T11) for TSAgroup. Propofol, fentanyl, atracurium, sevoflurane, and tracheal intubation were used for GA group. Intraoperative parameters, postoperative recovery and analgesia, complications as well as patient and surgeon satisfaction were compared between the three groups. All procedures were completed laparoscopically by the allocated method of anesthesia with no anesthetic conversions. The time for the blockade to reach T3 level, intraoperative hypotensive and bradycardic events and vasopressor use were significantly lower in (TSA group) than in (LSA group). Postoperative pain scores as assessed throughout any time, postoperative right shoulder pain and hospital stay was lower for both (TSA group) and (LSA group) compared with (GA group). The higher degree of patients satisfaction scores were recorded in patients under segmental TSA. The present study not only confirmed that both segmental TSA and conventional lumber spinal anesthesia (LSA) are safe and good alternatives to general anesthesia (GA) in healthy patients undergoing laparoscopic cholecystectomy but also showed better postoperative pain control of both spinal techniques when compared with general anesthesia. Segmental TSA provides better hemodynamic stability, lesser vasopressor use and early ambulation and discharge with higher degree of patient satisfaction making it excellent for day case surgery compared with conventional lumbar spinal anesthesia.

The rate of incisional hernia in high-risk patients (obesity, cancer, etc.) is high, even in laparoscopic surgery. The aim of this study is to evaluate the safety of the use of cyanoacrylate fixed prophylactic meshes in the assistance incision in overweight or obese patients undergoing laparoscopic colorectal surgery. A prospective, non-randomized cohort study of patients undergoing elective laparoscopic resection for colorectal cancer between January 2013 and March 2016 was performed. Those with a body mass index greater than 25kg / m 2 were evaluated to implant a prophylactic meshes fixed with cyanoacrylate (Histoacryl®) as reinforcement of the assistance incision. 52 patients were analyzed (mean body mass index: 28.4±2kg / m 2 ). Prophylactic meshes was implanted in 15 patients. The time to put the mesh in place was always less than 5minutes. There was no significant difference in wound infection rate (12% vs. 10%). No mesh had to be explanted. Although the mean follow-up was shorter (14.1±4 vs. 22.3±9 months), there were no incisional hernia in the mesh group. On the other hand, in the non-mesh group, 1 acute evisceration (2.7%) and 4 incisional hernia of the assistance incision were observed (10.8%). There were no significant differences between groups regarding trocar incisional hernia (6.6 vs. 5.4%). The implantation of a reinforcement prophylactic mesh in overweight or obese patients undergoing laparoscopic colorectal surgery is safe and seems to reduce the short-term rate of incisional hernia. Fixation with cyanoacrylate is a rapid method that facilitates the procedure without additional complications. Copyright © 2017 AEC. Publicado por Elsevier España, S.L.U. All rights reserved.

Most interventions aimed at reducing bleeding during myomectomy lack sufficient evidence regarding their effectiveness. Recently, it was reported that intraoperative ascorbic acid administration effectively reduced blood loss during abdominal myomectomy. Therefore, this study aimed to investigate whether intravenous ascorbic acid infusion would affect intraoperative blood loss in women undergoing laparoscopic myomectomy. A randomized, double-blind, parallel-group, placebo-controlled trial including 50 women undergoing laparoscopic myomectomy was conducted. Women with ≤4 myomas, ≤9cm in maximum diameter were eligible. The study:control group ratio was 1:1. Starting 30minutes before anesthesia, 2g of ascorbic acid or a placebo were administered for 2hours intraoperatively. Intraoperative blood loss, the primary endpoint, was calculated as the difference between the volume of fluids acquired from suction and that used for irrigation of the abdominal cavity during surgery using constant values. Among the 50 randomized women, 1 and 3 in the study and control groups, respectively, were excluded due to withdrawal of consent, cancelation of surgery, or non-measurement of the primary endpoint. The baseline and operative characteristics were similar between the study and control groups, as was the intraoperative blood loss (193±204mL vs. 159±193mL, P=0.52). In addition, the operating time (95±29min vs. 110±52min; P=0.50) and decrease in hemoglobin level after surgery (1.9±1.31g/dL vs. 1.4±1.4g/dL; P=0.24) were similar between the study and control groups. Intravenous ascorbic acid infusion did not reduce intraoperative blood loss in women undergoing laparoscopic myomectomy. ClinicalTrials.gov, www.clinicaltrials.gov, NCT01715597.

Laparoscopic myotomy: technique and efficacy in treating achalasia.

PubMed

Ali, A; Pellegrini, C A

2001-04-01

Esophageal Heller myotomy and a partial antireflux procedure for achalasia are the ideal procedures to benefit from the advances in minimally invasive surgery. The magnified view of the operative field provided by the laparoscope allows precise division of the esophageal muscle fibers with excellent results. Laparoscopic Heller myotomy results in reduced postoperative pain, less morbidity, shorter hospitalization, better resolution of dysphagia, and less postoperative heartburn when compared with the open abdominal and even the thoracoscopic approach. A longer myotomy especially at the distal end, and a loose, well-formed partial fundoplication are the keys to a successful outcome. Superior long-term results after surgical myotomy when compared with nonsurgical interventions argue strongly in favor of surgery in any patient who is fit enough to undergo general anesthesia.

Carbon dioxide embolism during laparoscopic sleeve gastrectomy

Bariatric restrictive and malabsorptive operations are being carried out in most countries laparoscopically. Carbon dioxide or gas embolism has never been reported in obese patients undergoing bariatric surgery. We report a case of carbon dioxide embolism during laparoscopic sleeve gastrectomy (LSG) in a young super obese female patient. Early diagnosis and successful management of this complication are discussed. An 18-year-old super obese female patient with enlarged fatty liver underwent LSG under general anesthesia. During initial intra-peritoneal insufflation with CO2 at high flows through upper left quadrant of the abdomen, she had precipitous fall of end-tidal CO2 and SaO2 % accompanied with tachycardia. Early suspicion led to stoppage of further insufflation. Clinical parameters were stabilized after almost 30 min, while the blood gas analysis was restored to normal levels after 1 h. The area of gas entrainment on the damaged liver was recognized by the surgeon and sealed and the surgery was successfully carried out uneventfully. Like any other laparoscopic surgery, carbon dioxide embolism can occur during bariatric laparoscopic surgery also. Caution should be exercised when Veress needle is inserted through upper left quadrant of the abdomen in patients with enlarged liver. A high degree of suspicion and prompt collaboration between the surgeon and anesthetist can lead to complete recovery from this potentially fatal complication. PMID:21772696

Resection quality after robot-assisted surgery for colorectal cancer have not previously been investigated in a nationwide study. The aim of the study was to examine the resection quality in robot-assisted versus laparoscopic surgery for colorectal cancer. Furthermore, 30-day mortality, postoperative complications, and conversion to open surgery were investigated. Patients undergoing either laparoscopic or robot-assisted surgery for colorectal cancer between 1 January 2010 and 31 December 2015 were included. The primary outcome was whether R0 resection was achieved. Secondary outcomes were 30-day mortality, postoperative complications, and conversions to laparotomy. A total of 8615 and 3934 patients had a diagnosis of colon cancer and rectal cancer respectively. Of the patients with colon cancer, 511 patients underwent robot-assisted surgery and of the patients with rectal cancer, 706 patients underwent robot-assisted surgery. In the multivariate analysis, patients with colon cancer had an odds ratio (OR) = 0.63 (95%CI 0.45-0.88) for receiving R0 resection in the robot-assisted group compared to laparoscopy. For patients with rectal cancer, the OR was 1.20 (95%CI 0.89-1.61). No difference in 30-day mortality or postoperative complications were observed. The OR of conversion to laparotomy was lower in the robot-assisted group compared to the laparoscopic group in both patients with colon - and rectal cancer. The study showed significant lower odds of receiving R0 resection in patients with colon cancer undergoing robot-assisted surgery. In patients with rectal cancer the robot-assisted surgery non-significantly increased the odds of receiving R0 resection. Copyright © 2018 Elsevier Ltd. All rights reserved.

For major laparoscopic surgery, as with open surgery, a multimodal analgesia plan can help to control postoperative pain. Placing a wound catheter intraoperatively following colon surgery could optimize the control of acute pain with less consumption of opioids and few adverse effects. We conducted a prospective, randomized, study of patients scheduled to undergo laparoscopic colon surgery for cancer in Galdakao-Usansolo Hospital from January 2012 to January 2013. Patients were recruited and randomly allocated to wound catheter placement plus standard postoperative analgesia or standard postoperative analgesia alone. A physician from the acute pain management unit monitored all patients for pain at multiple points over the first 48 hours after surgery. The primary outcome variables were verbal numeric pain scale scores and amount of intravenous morphine used via patient controlled infusion. 92 patients were included in the study, 43 had a wound catheter implanted and 49 did not. Statistically significant differences in morphine consumption were observed between groups throughout the course of the treatment period. The mean total morphine consumption at the end of the study was 5.63±5.02mg among wound catheter patients and 21. 86±17.88mg among control patients (P=.0001). Wound catheter patients had lower pain scale scores than control patients throughout the observation period. No adverse effects associated with the wound catheter technique were observed. The wound catheter group showed lower hospital stays with statistically significant difference (P=.02). In patients undergoing laparoscopic colon surgery, continuous infusion of local anaesthetics through interfascial wound catheters during the first 48h aftersurgery reduced the level of perceived pain and also reduced parenteral morphine consumption with no associated adverse effects and lower hospital stays.

The number of weight reduction operations performed for type II and type III obesity is rapidly escalating. Risk of surgery has been infrequently stratified for patient subgroups. The purpose of this study was to identify patient characteristics that increased the odds of a prolonged hospital length of stay (LOS) following open or laparoscopic Roux-en-Y gastric bypass (RYGBP). The hospital records of 311 patients who underwent RYGBP in a 6-month period were retrospectively reviewed. Patient characteristics including the presence of significant obesity-related medical conditions were recorded. Analysis was based on intent to treat. Univariate and step-wise logistic regression analysis was used to identify the odds ratio (OR) and adjusted odds ratio (AOR) for predictors of an increased hospital LOS. Datasets for 311 patients were complete.159 patients underwent open vertical banded gastro-plasty-Roux-en-Y gastric bypass (VBG-RYGBP) and152 laparoscopic RYGBP (LRYGBP). 78% of patients were female. Median age was 40 years (range 18-68). Median BMI was 49 kg/m2 (range 35-82). 17% of patients had sleep apnea, 18% asthma, 19% type 2 diabetes, 13% hypercholesterolemia and 44% hypertension. Median length of surgery for open VBG-RYGBP (64 minutes) was significantly faster than forLRYGBP (105 minutes). Median length of stay was significantly shorter for LRYGBP (2 days) than openVBG-RYGBP (3 days). Univariate logistic regression analysis identified 6 predictors of increased LOS:open surgery (0.4 OR); increasing BMI (60 kg/m2 0.38 OR; BMI 70 kg/m2 0.53 OR); increasing length of surgery (120 min 0.33 OR; 180 min 0.48 OR); sleep apnea (2.25 OR); asthma (3.73 OR); and hypercholesterolemia (3.73 OR). Subset analysis identified patients with the greatest odds for a prolonged hospital stay: women with asthma (2.47 AOR) or coronary artery disease (8.65 AOR); men with sleep apnea (5.54 OR) or the metabolic syndrome (6.67-10.20 OR); and patients undergoing a laparoscopic operation with sleep apnea (11.53 AOR) or coronary artery disease(12.15 AOR). Open surgery, BMI, length of surgery,sleep apnea, asthma and hypercholesterolemia all increased the odds of a prolonged LOS. Patients with the greatest odds of long LOS were women with asthma or coronary disease, men with sleep apnea or the metabolic syndrome, and patients undergoing laparoscopic surgery with sleep apnea or coronary artery disease. Patients at high-risk for prolonged hospital stay can be identified before undergoingRYGBP. Surgeons may wish to avoid high-risk patients early in their bariatric surgery experience.

Current Laparoscopic simulators have limited usefulness and patients have been used for training since the dawn of surgery. NUGITS (Northumbrian Upper Gastro Intestinal Team of Surgeons) Laparoscopic Skills courses utilise hands-on experience with simulators moving to live operating on volunteer patients. It is vital to know that the volunteer patient is not disadvantaged by greater surgical risk. This was a case-controlled prospective comparison of patients undergoing both Laparoscopic Cholecystectomy (LC) [n=51] and Laparoscopic Inguinal Hernia (LIH) [n=62] during NUGITS training courses. They are compared with a matched (age, sex and ASA grade) control group LC (n=51) and LIH (n=62) operated on by consultants. The outcome measures were surgical peri-and post-operative complications, post-operative hospital stay, readmission and early recurrence of inguinal hernia (<6 months). In the LC cohort, there was no significant difference in the length of hospital stay (p=0.07) or readmission (p=0.16) in both the groups. The mean operating time was higher in the trainee compared to the control group (p=0.001). There was no difference in the post-operative morbidity or mortality in either group. In LIH cohort, the mean operating time was higher in the trainee compared with the control group. There was no significant difference in post-operative complications (p>0.05) and early post-operative recurrence of hernia (p>0.05). The post-operative outcomes of patients undergoing laparoscopic surgery during laparoscopic training courses are similar to consultant-operated patients. Thus, it is acceptable and safe to encourage patients to volunteer for laparoscopic training courses.

Laparoscopic partial fundoplication for gastro-oesophageal reflux disease (GORD) is reported to have fewer side effects when compared to Nissen fundoplication, but doubts remain over its long term durability in controlling reflux. The aim of this study was to assess outcome of symptoms for all patients presenting with GORD undergoing routine laparoscopic subtotal Lind fundoplication. All patients undergoing laparoscopic fundoplication between August, 1999 and November, 2007 performed by a single surgeon were included in the study. The anti-reflux procedure studied was laparoscopic Lind (300°) fundoplication with crural repair in all cases. Patients completed pre and post-operative questionnaires containing validated scoring systems for heartburn, gas bloat, dysphagia and overall patient satisfaction. Over the 100-month period, 320 consecutive patients underwent laparoscopic subtotal Lind fundoplication. Of these, 256 (80%) replied to the questionnaire at a mean of 31 months (range 3-96 months) following surgery. 91.4% of respondents had an improvement in heartburn symptom score with a significant reduction in score from 7.74 preoperatively to 1.25 postoperatively (p<0.001). There was also a significant reduction of mean modified Visick score for reflux control (heartburn and regurgitation) from 3.49 preoperatively to 1.48 after surgery (p<0.001). In total, 22 patients developed recurrent reflux symptoms with half of these reporting their recurrence within two years following surgery. Because of this all were tested with post-operative pH testing, yet only one had a 24-h pH time outside the normal range. Overall patient satisfaction was high with a visual analogue score of 9 and 88% of the patients claimed they would have the operation again. Laparoscopic Lind fundoplication demonstrates excellent reflux control when performed routinely for all patients presenting with GORD. This technique is both durable and efficacious in controlling reflux symptoms. Copyright © 2014 Surgical Associates Ltd. Published by Elsevier Ltd. All rights reserved.

Single-incision laparoscopic surgery (SILS) is gaining popularity for a wide variety of surgical operations and capitalizes on the benefits of traditional laparoscopic surgery without incurring multiple incision sites. Traditionally, SILS is performed by a midline periumbilical approach. However, such a minimally invasive approach may be utilized in patients who already have an abdominal incision. Our series retrospectively reviews 7 cases in which we utilized the fascial defect at the time of after ostomy reversal as our SILS incision site. In turn, we performed a variety of concurrent intra-abdominal procedures with excellent technical success and outcomes. Our study is the largest single-institution case series of this novel approach and suggests that utilizing an existing ostomy-site abdominal incision is a safe and effective location for SILS port placement and should be considered in patients undergoing concurrent procedures.

To evaluate the alterations on surgical outcomes after of the implementation of 3D laparoscopic technology for the surgical treatment of early-stage cervical carcinoma. Data of patients undergoing type B radical hysterectomy (with or without bilateral salpingo-oophorectomy) and pelvic lymphadenectomy via 3D laparoscopy were compared with a historical cohort of patients undergoing type B radical hysterectomy via conventional laparoscopy. Complications (within 60 days) were graded per the Accordion severity system. Data of 75 patients were studied: 15 (20%) and 60 (80%) patients undergoing surgery via 3D laparoscopy and conventional laparoscopy, respectively. Baseline patient characteristics as well as pathologic findings were similar between groups (p>0.1). Patients undergoing 3D laparoscopy experienced a trend toward shorter operative time than patients undergoing conventional laparoscopy (176.7 ± 74.6 vs 215.9 ± 61.6 minutes; p = 0.09). Similarly, patients undergoing 3D laparoscopic radical hysterectomy experienced shorter length of hospital stay (2 days, range 2-6, vs 4 days, range 3-11; p<0.001) in comparison to patients in the control group, while no difference in estimated blood loss was observed (p = 0.88). No between-group difference in complication rate was observed. 3D technology is a safe and effective way to perform type B radical hysterectomy and pelvic node dissection in early-stage cervical cancer. Further large prospective studies are warranted in order to assess the cost-effectiveness of the introduction of 3D technology in comparison to robotic assisted surgery.

This study aimed to evaluate laparoscopic dismembered pyeloplasty compared with open surgery and to determine whether the morbidity and outcome rates are different in each of these techniques. We report our 10-year experience with open and laparoscopic pyeloplasty at one istitution. From February 1999 to October 2010, 49 patients with ureteropelvic junction obstruction were assigned into two groups. 25 patients underwent open surgical pyeloplasty (period 1999-2010) and 24 underwent laparoscopic pyeloplasty (period 2004-2010). 25 patients undergoing open pyeloplasty had a retroperitoneal flank approach. Of the 24 laparoscopic cases 18 had a transperitoneal retrocolic access, 1 had a transperitoneal transmesocolic access and 5 had a retroperitoneal access. In all 49 cases an Anderson-Hynes dismembered pyeloplasty was used. We retrospectively compared the operative time, hospital stay, perioperative complications and follow-up of the two groups. Clinical symptoms were assessed before and after surgery, subjectively. Patients dermographic data were similar between the two groups with mean age of 42 years (range 6-78) and with a male/female ratio of 1:1.45. A crossing vessel could be identified in 37.5% (9/24) with laparoscopy vs. 32% (8/25) in open surgery. Compared with open procedures, laparoscopic procedures were associated with a longer mean operating time (274 vs 143 min), a shorter mean hospital stay (9.9 vs 15.8 day) and the perioperative complication rates were 16.7% for laparoscopic pyeloplasties and 20% for open pyeloplasties. The success rates were 90.5% for laparoscopy and 90.9% for open surgery. Average follow-up was 40.9 month for the laparoscopic group and 72.3 month for the open group. Failed procedures showed no improvement in loin pain or obstruction. The efficacy (in term of success rate and perioperative complications) of laparoscopic pyeloplasty is comparable to that of open pyeloplasty, with shorter mean hospital stay and better cosmetic results. These findings may suggest, that the laparoscopic dismembered pyeloplasty has the potential to replace open surgery and may be considered the first option for the treatment of ureteropelvic junction obstruction in expert hands.

Laparoscopic Sleeve Gastrectomy in the Postpartum Period: Increased Risk of Bleeding, a Challenging Situation.

The female population represents three-fourths of patients undergoing a bariatric procedure and could be scheduled for surgery in their postpartum period. We report a difficult case of a female patient who underwent a laparoscopic sleeve gastrectomy 6 weeks postpartum. The postpartum period is accompanied by pronounced vasodilatation with transient portal hypertension. Most of the hemodynamic alterations occurring during pregnancy return to baseline within 6-8 weeks after delivery. Bariatric surgery in the postpartum period should be avoided in order for the cardiovascular system to regain its normality.

PubMed Central

Karthik, Somu; Augustine, Alfred Joseph; Shibumon, Mundunadackal Madhavan; Pai, Manohar Varadaraya

2013-01-01

CONTEXT: The rate of port site complications following conventional laparoscopic surgery is about 21 per 100,000 cases. It has shown a proportional rise with increase in the size of the port site incision and trocar. Although rare, complications that occur at the port site include infection, bleeding, and port site hernia. AIMS: To determine the morbidity associated with ports at the site of their insertion in laparoscopic surgery and to identify risk factors for complications. SETTINGS AND DESIGN: Prospective descriptive study. MATERIALS AND METHODS: In the present descriptive study, a total of 570 patients who underwent laparoscopic surgeries for various ailments between August 2009 and July 2011 at our institute were observed for port site complications prospectively and the complications were reviewed. STATISTICAL ANALYSIS USED: Descriptive statistical analysis was carried out in the present study. The statistical software, namely, SPSS 15.0 was used for the analysis of the data. RESULTS: Of the 570 patients undergoing laparoscopic surgery, 17 (3%) had developed complications specifically related to the port site during a minimum follow-up of three months; port site infection (PSI) was the most frequent (n = 10, 1.8%), followed by port site bleeding (n = 4, 0.7%), omentum-related complications (n = 2; 0.35%), and port site metastasis (n = 1, 0.175%). CONCLUSIONS: Laparoscopic surgeries are associated with minimal port site complications. Complications are related to the increased number of ports. Umbilical port involvement is the commonest. Most complications are manageable with minimal morbidity, and can be further minimized with meticulous surgical technique during entry and exit. PMID:23741110

During the past several decades, early rehabilitation programs for the care of patients with colorectal surgery have gained popularity. Several randomized controlled trials and meta-analyses have confirmed that the implementation of these evidence-based detailed perioperative care protocols is useful for early recovery of patients after colorectal resection. Patients cared for based on these protocols had a rapid recovery of bowel movement, shortened length of hospital stay, and fewer complications compared with traditional care programs. However, most of the previous evidence was obtained from studies of early rehabilitation programs adapted to open colonic resection. Currently, limited evidence exists on the effects of early rehabilitation after laparoscopic rectal resection, although this procedure seems to be associated with a higher morbidity than that reported with traditional care. In this article, we review previous studies and guidelines on early rehabilitation programs in patients undergoing rectal surgery. We investigated the status of early rehabilitation programs in rectal surgery and analyzed the limitations of these studies. We also summarized indications and detailed protocol components of current early rehabilitation programs after rectal surgery, focusing on laparoscopic resection. PMID:24379571

OBJECTIVE To describe the technique, clinical findings, and short-term outcome in dogs undergoing laparoscopic-assisted incisional gastropexy with a reusable single-incision surgery port. DESIGN Retrospective case series. ANIMALS 14 client-owned dogs. PROCEDURES Medical records of dogs referred for elective laparoscopic gastropexy between June 2012 and August 2013 were reviewed. History, signalment, results of physical examination and preoperative laboratory testing, surgical procedure, duration of surgery, postoperative complications, duration of hospital stay, and short-term outcome were recorded. All patients underwent general anesthesia and were positioned in dorsal recumbency. After an initial limited laparoscopic exploration, single-incision laparoscopic-assisted gastropexy was performed extracorporeally in all dogs via a conical port placed in a right paramedian location. Concurrent procedures included laparoscopic ovariectomy (n = 4), gastric biopsy (2), and castration (7). Short-term outcome was evaluated. RESULTS Median duration of surgery was 76 minutes (range, 40 to 90 minutes). Intraoperative complications were minor and consisted of loss of pneumoperitoneum in 2 of 14 dogs. A postoperative surgical site infection occurred in 1 dog and resolved with standard treatment. Median duration of follow-up was 371 days (range, 2 weeks to 1.5 years). No dogs developed gastric dilation-volvulus during the follow-up period, and all owners were satisfied with the outcome. CONCLUSIONS AND CLINICAL RELEVANCE Results suggested that single-incision laparoscopic-assisted gastropexy with a reusable conical port was feasible and effective in appropriately selected cases. Investigation of the potential benefits of this reusable port versus single-use devices for elective gastropexy in dogs is warranted.

Background and Objectives: Single-site laparoscopic colorectal surgery has been firmly established; however, few reports addressing this technique in the inflammatory bowel disease population exist. Methods: We conducted a case-matched retrospective review of 20 patients who underwent single-site laparoscopic procedures for inflammatory bowel disease compared with 20 matched patients undergoing multiport laparoscopic procedures. Data regarding these patients were tabulated in the following categories: demographic characteristics, operative parameters, and perioperative outcomes. Results: A wide range of cases were completed: 9 ileocolic resections, 7 cases of proctocolectomy with end ileostomy or ileal pouch anal anastomosis, 2 cases of proctectomy with ileal pouch anal anastomosis, and 2 total abdominal colectomies with end ileostomy were all matched to equivalent multiport laparoscopic cases. No single-incision cases were converted to multiport laparoscopy, and 2 single-incision cases (10%) were converted to an open approach. For single-incision cases, the mean length of stay was 7.7 days, the mean time to oral intake was 3.3 days, and the mean period of intravenous analgesic use was 5.0 days. There were no statistically significant differences between single-site and multiport cases. Conclusions: Single-site laparoscopic surgery is technically feasible in inflammatory bowel disease. The length of stay and period of intravenous analgesic use (in days) appear to be higher than those in comparable series examining outcomes of single-site laparoscopic colorectal surgery, and the outcomes are comparable with those of multiport laparoscopy. This may be because of the nature of inflammatory bowel disease, limiting the benefits of a single-site approach in this population. PMID:24960490

Data on specific abdominal surgery and Cushing's syndrome are infrequent and are usually included in the adrenalectomy reports. Current literature suggests the feasibility and reproducibility of the surgical adrenalectomies for patients diagnosed with non-functioning tumours and functioning adrenal tumours including pheochromocytoma, Conn's syndrome and Cushing's syndrome. Medical treatment for Cushing's syndrome is feasible but follow-up or clinical situations force the patient to undergo a surgical procedure. Laparoscopic surgery has become a gold standard nowadays in a broad spectrum of pathologies. Laparoscopic adrenalectomies are also standard procedures nowadays. However, despite the different characteristics and clinical disorders related to the laparoscopically removed adrenal tumours, the intraoperative and postoperative outcomes do not significantly differ in most cases between the different groups of patients, techniques and types of tumours. Tumour size, hormonal type and surgeon's experience could be different factors that predict intraoperative and postoperative complications. Transabdominal and retroperitoneal approaches can be considered. Outcomes for Cushing's syndrome do not differ depending on the surgical approach. Novel technologies and approaches such as single-port surgery or robotic surgery have proven to be safe and feasible. Laparoscopic adrenalectomy is a safe and feasible approach to adrenal pathology, providing the patients with all the benefits of minimally invasive surgery. Single-port access and robotic surgery can be performed but more data are required to identify their correct role between the different surgical approaches. Factors such as surgeon's experience, tumour size and optimal technique can affect the outcomes of this surgery.

Surgical value is based on optimizing clinical and financial outcomes. The clinical benefits of laparoscopic surgery are well established; however, many patients are still not offered a laparoscopic procedure. Our objective was to compare the modern clinical and financial outcomes of laparoscopic and open colorectal surgery. The Premier Perspective database identified patients undergoing elective colorectal resections from January 1, 2013 to December 31, 2013. Cases were stratified by operative approach into laparoscopic and open cohorts. Groups were controlled on all demographics, diagnosis, procedural, hospital characteristics, surgeon volume, and surgeon specialty and then compared for clinical and financial outcomes. The main outcome measures were length of stay (LOS), complications, readmission rates, and cost by surgical approach. A total of 6343 patients were matched and analyzed in each cohort. The most common diagnosis was diverticulitis (p = 0.0835) and the most common procedure a sigmoidectomy (p = 0.0962). The LOS was significantly shorter in laparoscopic compared to open (mean 5.78 vs. 7.80 days, p < 0.0001). The laparoscopic group had significantly lower readmission (5.82 vs. 7.68 %, p < 0.0001), complication (32.60 vs. 42.28 %, p < 0.0001), and mortality rates (0.52 vs. 1.28 %, p < 0.0001). The total cost was significantly lower in laparoscopic than in open (mean $17,269 vs. $20,552, p < 0.0001). By category, laparoscopy was significantly more cost-effective for pharmacy (p < 0.0001), room and board (p < 0.0001), recovery room (p = 0.0058), ICU (p < 0.0001), and laboratory and imaging services (both p < 0.0001). Surgical supplies (p < 0.0001), surgery (p < 0.0001), and anesthesia (p = 0.0053) were higher for the laparoscopic group. Laparoscopy is more cost-effective and produces better patient outcomes than open colorectal surgery. Minimally invasive colorectal surgery is now the standard that should be offered to patients, providing value to both patient and provider.

This study aims to evaluate the clinical and quality of health outcomes in patients undergoing laparoscopic repair of intrathoracic stomach with or without gastric volvulus. From January 2007 to December 2013, a prospectively maintained data, of patients undergoing surgical repair of intrathoracic stomach, with or without gastric volvulus, was reviewed. Patient demographics, ASA grade, diagnostic technique, semiurgent/emergency status, type of volvulus if present, details of surgery and perioperative complications were recorded. Validated SF-36 questionnaires were completed by patients to record preoperative and postoperative quality of life (QoL) status. Patients managed by nonoperative measures were excluded from the study. Thirty patients were identified with intrathoracic stomach. Fourteen patients had gastric volvulus. Twenty-seven patients (10 emergency, 17 semiurgent) underwent laparoscopic repair of intrathoracic stomach and were included in the study. Mean operating time was 156 (SD, 37.5; range, 105 to 230) minutes. All 27 operations were completed by laparoscopic approach. There was no conversion to open procedure or mortality at 30 days. Mean hospital stay was 5.2 (range, 1 to 15) days. There were 3 (11%) early postoperative complications. One (3.7%) patient developed recurrence at 2 years which required reoperation. Mean follow-up was 10.5 (range, 1 to 36) months. ASA grade and operative time determined the postoperative hospital stay (P=0.001, 0.001, respectively), whereas body mass index and age were shown to have no influence. Patient-reported QoL scores improved across all scales of the health questionnaire after surgery especially bodily pain, social functioning, and physical functioning. Laparoscopic surgery is a safe and effective treatment option for intrathoracic stomach, with or without gastric volvulus. It is associated with low rates of complications and recurrence. Self-reported patient data shows significant improvement to overall QoL after surgery for intrathoracic stomach.

Objective. To evaluate the effects of diaphragmatic breathing exercises and flow and volume-oriented incentive spirometry on pulmonary function and diaphragm excursion in patients undergoing laparoscopic abdominal surgery. Methodology. We selected 260 patients posted for laparoscopic abdominal surgery and they were block randomization as follows: 65 patients performed diaphragmatic breathing exercises, 65 patients performed flow incentive spirometry, 65 patients performed volume incentive spirometry, and 65 patients participated as a control group. All of them underwent evaluation of pulmonary function with measurement of Forced Vital Capacity (FVC), Forced Expiratory Volume in the first second (FEV1), Peak Expiratory Flow Rate (PEFR), and diaphragm excursion measurement by ultrasonography before the operation and on the first and second postoperative days. With the level of significance set at p < 0.05. Results. Pulmonary function and diaphragm excursion showed a significant decrease on the first postoperative day in all four groups (p < 0.001) but was evident more in the control group than in the experimental groups. On the second postoperative day pulmonary function (Forced Vital Capacity) and diaphragm excursion were found to be better preserved in volume incentive spirometry and diaphragmatic breathing exercise group than in the flow incentive spirometry group and the control group. Pulmonary function (Forced Vital Capacity) and diaphragm excursion showed statistically significant differences between volume incentive spirometry and diaphragmatic breathing exercise group (p < 0.05) as compared to that flow incentive spirometry group and the control group. Conclusion. Volume incentive spirometry and diaphragmatic breathing exercise can be recommended as an intervention for all patients pre- and postoperatively, over flow-oriented incentive spirometry for the generation and sustenance of pulmonary function and diaphragm excursion in the management of laparoscopic abdominal surgery.

A suture-based liver retraction method for laparoscopic bariatric procedures: results from a large case series.

PubMed

Laparoscopic bariatric surgery requires retraction of the left lobe of the liver to provide adequate operative view and working space. Conventional approaches utilize a mechanical retractor and require additional incision(s), and at times an assistant. This study evaluated the safety and efficacy of a suture-based method of liver retraction in a large series of patients undergoing laparoscopic bariatric surgery. This method eliminates the need for a subxiphoid incision for mechanical retraction of the liver. Two hospitals in the Midwest with a high volume of laparoscopic bariatric cases. Retrospective chart review identified all patients undergoing bariatric surgery for whom suture-based liver retraction was selected. The left lobe of the liver is lifted, and sutures are placed across the right crus of the diaphragm and were either anchored on the abdominal wall or intraperitoneally to provide static retraction of the left lobe of the liver. In all, 487 cases were identified. Patients had a high rate of morbid obesity (83% with body mass index >40 kg/m(2)) and diabetes (34.3%). The most common bariatric procedures were Roux-en-Y gastric banding (39%) and sleeve gastrectomy (24.6%). Overall, 6 injuries to the liver were noted, only 2 of which were related to the suture-based retraction technique. Both injuries involved minor bleeding and were successfully managed during the procedure. The mean number of incisions required was 4.6. Suture-based liver retraction was found to be safe and effective in this large case series of morbidly obese patients. The rate of complications involving the technique was extremely low (.4%).

We aimed to investigate whether fluid therapy with a goal of near-maximal stroke volume (SV) guided by oesophageal Doppler (ED) monitoring result in a better outcome than that with a goal of maintaining bodyweight (BW) and zero fluid balance in patients undergoing colorectal surgery. In a double-blinded clinical multicentre trial, 150 patients undergoing elective colorectal surgery were randomized to receive fluid therapy after either the goal of near-maximal SV guided by ED (Doppler, D group) or the goal of zero balance and normal BW (Zero balance, Z group). Stratification for laparoscopic and open surgery was performed. The postoperative fluid therapy was similar in the two groups. The primary endpoint was postoperative complications defined and divided into subgroups by protocol. Analysis was performed by intention-to-treat. The follow-up was 30 days. The trial had 85% power to show a difference between the groups. The number of patients undergoing laparoscopic or open surgery and the patient characteristics were similar between the groups. No significant differences between the groups were found for overall, major, minor, cardiopulmonary, or tissue-healing complications (P-values: 0.79; 0.62; 0.97; 0.48; and 0.48, respectively). One patient died in each group. No significant difference was found for the length of hospital stay [median (range) Z: 5.00 (1-61) vs D: 5.00 (2-41); P=0.206]. Goal-directed fluid therapy to near-maximal SV guided by ED adds no extra value to the fluid therapy using zero balance and normal BW in patients undergoing elective colorectal surgery.

Yousef, Gamal T.; Lasheen, Ahmed E.

2012-01-01

Background: Laparoscopic cholecystectomy became the standard surgery for gallstone disease because of causing less postoperative pain, respiratory compromise and early ambulation. Objective: This study was designed to compare spinal anesthesia, (segmental thoracic or conventional lumbar) vs the gold standard general anesthesia as three anesthetic techniques for healthy patients scheduled for elective laparoscopic cholecystectomy, evaluating intraoperative parameters, postoperative recovery and analgesia, complications as well as patient and surgeon satisfaction. Materials and Methods: A total of 90 patients undergoing elective laparoscopic cholecystectomy, between January 2010 and May 2011, were randomized into three equal groups to undergo laparoscopic cholecystectomy with low-pressure CO2 pneumoperitoneum under segmental thoracic (TSA group) or conventional lumbar (LSA group) spinal anesthesia or general anesthesia (GA group). To achieve a T3 sensory level we used (hyperbaric bupivacaine 15 mg, and fentanyl 25 mg at L2/L3) for LSAgroup, and (hyperbaric bupivacaine 7.5 mg, and fentanyl 25 mg at T10/T11) for TSAgroup. Propofol, fentanyl, atracurium, sevoflurane, and tracheal intubation were used for GA group. Intraoperative parameters, postoperative recovery and analgesia, complications as well as patient and surgeon satisfaction were compared between the three groups. Results: All procedures were completed laparoscopically by the allocated method of anesthesia with no anesthetic conversions. The time for the blockade to reach T3 level, intraoperative hypotensive and bradycardic events and vasopressor use were significantly lower in (TSA group) than in (LSA group). Postoperative pain scores as assessed throughout any time, postoperative right shoulder pain and hospital stay was lower for both (TSA group) and (LSA group) compared with (GA group). The higher degree of patients satisfaction scores were recorded in patients under segmental TSA. Conclusion: The present study not only confirmed that both segmental TSA and conventional lumber spinal anesthesia (LSA) are safe and good alternatives to general anesthesia (GA) in healthy patients undergoing laparoscopic cholecystectomy but also showed better postoperative pain control of both spinal techniques when compared with general anesthesia. Segmental TSA provides better hemodynamic stability, lesser vasopressor use and early ambulation and discharge with higher degree of patient satisfaction making it excellent for day case surgery compared with conventional lumbar spinal anesthesia.

Background Tumors may induce systemic immune dysfunction, which can be aggravated by surgery and anesthesia/analgesia. Data on the effect of flurbiprofen preemptive analgesia on immune dysfunction is limited. The aim of this study was to investigate the effect of flurbiprofen preemptive analgesia on lymphocytes and natural killer (NK) cells in patients undergoing thoracotomy and thoracoscopy radical esophagectomy, and to explore the analgesic methods suitable for tumor patients. Methods This was a randomized controlled pilot study of 89 patients with esophageal cancer treated with surgery at the Henan Cancer Hospital between January 1, 2015 and December 31, 2016. The patients were divided into three groups: group 1, thoracotomy; group 2, thoracoscopy and laparoscopic surgery; and group 3, flurbiprofen, thoracoscopy, and laparoscopic surgery. CD3+, CD19+, NK, CD4+, and CD8+ cells in whole blood were measured by flow cytometry 30 minutes before surgery (T0), at the end of the thoracic section of the procedure (T1), and at the end of the operation (T2). Results There were no significant differences in CD3+, CD19+, CD8+, NK, and CD4+ cells between the three groups or regarding the time points during the procedure (all P > 0.05). Thoracotomy and thoracoscopy surgery resulted in similar immunological outcomes. Conclusion Flurbiprofen ester preemptive analgesia did not suppress the immune function in patients and could be a safe analgesic method for patients with esophageal cancer undergoing surgery.

Prospective randomized trial of 40 consecutive patients undergoing laparoscopic cholecystectomy. Comparison criteria included predictive ultrasound factors of difficult cholecystectomy, previous history of complicated biliary disease and demographics. Results are analyzed in terms of ambulatorization rate, pain, analgesic requirements, postoperative recovery, technical difficulty, hemorrhage intensity, overnight stay, readmission rate and total or partial conversion. Both procedures were similar in surgery time, technical score and hemorrhage score. MLC was associated with similar ambulatorization rate, 85%, and over-night stay 15%, with only 15% partial conversion rate. MLC showed less postoperative pain (P=.026), less analgesic consumption (P=.006) and similar DAR (P=.879). MLC is similar to CLMP in terms of ambulatorization with less postoperative pain and analgesic requirements without differences in postoperative recovery. Copyright © 2014 AEC.

Importance Robotic rectal cancer surgery is gaining popularity, but limited data are available regarding safety and efficacy. Objective To compare robotic-assisted vs conventional laparoscopic surgery for risk of conversion to open laparotomy among patients undergoing resection for rectal cancer. Design, Setting, and Participants Randomized clinical trial comparing robotic-assisted vs conventional laparoscopic surgery among 471 patients with rectal adenocarcinoma suitable for curative resection conducted at 29 sites across 10 countries, including 40 surgeons. Recruitment of patients was from January 7, 2011, to September 30, 2014, follow-up was conducted at 30 days and 6 months, and final follow-up was on June 16, 2015. Interventions Patients were randomized to robotic-assisted (n = 237) or conventional (n = 234) laparoscopic rectal cancer resection, performed by either high (upper rectum) or low (total rectum) anterior resection or abdominoperineal resection (rectum and perineum). Main Outcomes and Measures The primary outcome was conversion to open laparotomy. Secondary end points included intraoperative and postoperative complications, circumferential resection margin positivity (CRM+) and other pathological outcomes, quality of life (36-Item Short Form Survey and 20-item Multidimensional Fatigue Inventory), bladder and sexual dysfunction (International Prostate Symptom Score, International Index of Erectile Function, and Female Sexual Function Index), and oncological outcomes. Results Among 471 randomized patients (mean [SD] age, 64.9 [11.0] years; 320 [67.9%] men), 466 (98.9%) completed the study. The overall rate of conversion to open laparotomy was 10.1%: 19 of 236 patients (8.1%) in the robotic-assisted laparoscopic group and 28 of 230 patients (12.2%) in the conventional laparoscopic group (unadjusted risk difference = 4.1% [95% CI, −1.4% to 9.6%]; adjusted odds ratio = 0.61 [95% CI, 0.31 to 1.21]; P = .16). The overall CRM+ rate was 5.7%; CRM+ occurred in 14 (6.3%) of 224 patients in the conventional laparoscopic group and 12 (5.1%) of 235 patients in the robotic-assisted laparoscopic group (unadjusted risk difference = 1.1% [95% CI, −3.1% to 5.4%]; adjusted odds ratio = 0.78 [95% CI, 0.35 to 1.76]; P = .56). Of the other 8 reported prespecified secondary end points, including intraoperative complications, postoperative complications, plane of surgery, 30-day mortality, bladder dysfunction, and sexual dysfunction, none showed a statistically significant difference between groups. Results Among 471 randomized patients (mean [SD] age, 64.9 [11.0] years; 320 [67.9%] men), 466 (98.9%) completed the study. The overall rate of conversion to open laparotomy was 10.1%. The overall CRM+ rate was 5.7%. Of the other 8 reported prespecified secondary end points, including intraoperative complications, postoperative complications, plane of surgery, 30-day mortality, bladder dysfunction, and sexual dysfunction, none showed a statistically significant difference between groups. End Point No. With Outcome/Total No. (%) Unadjusted Risk Difference (95% CI), % Adjusted Odds Ratio (95% CI) P Value Conventional Laparoscopy Robotic-Assisted Laparoscopy Conversion to open laparotomy 28/230 (12.2) 19/236 (8.1) 4.1 (−1.4 to 9.6) 0.61 (0.31-1.21) .16 CRM+ 14/224 (6.3) 12/235 (5.1) 1.1 (−3.1 to 5.4) 0.78 (0.35-1.76) .56 Conclusions and Relevance Among patients with rectal adenocarcinoma suitable for curative resection, robotic-assisted laparoscopic surgery, as compared with conventional laparoscopic surgery, did not significantly reduce the risk of conversion to open laparotomy. These findings suggest that robotic-assisted laparoscopic surgery, when performed by surgeons with varying experience with robotic surgery, does not confer an advantage in rectal cancer resection.

Kim, William; Abdelshehid, Corollos; Lee, Hak J; Ahlering, Thomas

2012-06-01

To discuss a technique currently used at our institution for the management of umbilical hernias during robot-assisted laparoscopic prostatectomy. As more patients undergo robot-assisted radical prostatectomy, there will be an increase in patients who qualify for robotic surgery with comorbidities. This technique has been utilized in clinically localized prostate cancer patients with umbilical hernias using the da Vinci Surgical System and standard laparoscopic instrumentation. Port placements and closures were performed by a resident assistant and a nurse at the operating table. The prostatectomy was performed by a single experienced surgeon at the console. Currently, no data are available regarding patients with umbilical hernias undergoing robotic prostatectomy. We reviewed our technique of port placement for patients with a pre-existing umbilical hernia undergoing robot-assisted laparoscopic prostatectomy. This technique allows for a reduction of the umbilical hernia, the use of the fascial defect as a robotic port, and the removal of the prostate by way of transverse incision and transverse repair. In our experience, this technique is feasible and reproducible for any small or large umbilical hernia. Copyright © 2012 Elsevier Inc. All rights reserved.

The aim of this study was to evaluate the analgesic efficacy and safety of rectus sheath block combined with intraperitoneal instillation using two doses of ropivacaine in patients undergoing laparoscopic gynecological surgery. Altogether 53 consenting women were randomized to receive intraperitoneal infiltration with 0.25% ropivacaine or 0.5% ropivacaine followed by rectus sheath block with 0.375% ropivacaine. The outcomes of clinical safety were measured using plasma concentration of local anesthetics and occurrence of toxic symptoms. The analgesic efficacy was assessed using numerical rating scales for pain and morphine consumption up to 24 hours after surgery. Patients' baseline characteristics, surgical factors, and analgesic outcomes were comparable between the two groups. Although peak plasma concentration of ropivacaine was significantly higher in patients receiving 0.5% ropivacaine, none of analyzed concentrations was above the toxic ones. Besides, no patients showed any symptoms of local anesthetic toxicity. The present study showed that the combination of rectus sheath block with intraperitoneal instillation of ropivacaine was safe and potent enough to relieve pain after laparoscopic surgery.

We present our experience with same-day discharge (without an overnight stay) after laparoscopic sleeve gastrectomy (SG) in 821 consecutive patients from 2011 to 2015. This is the largest series published to date of patients undergoing ambulatory surgery for such a procedure. To review our outcomes from ambulatory SG over 52 months to determine if SG can be safely performed in the ambulatory setting. Ambulatory surgery center. Retrospective review of all consecutive patients undergoing ambulatory SG from January 2011 to April 2015. All patients were discharged home the same day after surgery without an overnight stay at the hospital. Incidence of complications and admission to the hospital after discharge was reviewed up to 30 days from surgery. From January 2011 to April 2015, 821 consecutive patients underwent SG. Nineteen 30-day complications occurred in the series, 17 of them requiring admission to the hospital. Of the 19 cases, gastric leaks accounted for 7, intr-aabdominal abscess for 4, and dehydration/nausea/vomiting for 4; 4 were due to other causes. Complication and readmission rates at 30 days were 2.3% and 2.1%, respectively. Follow-up at 30 days was 98.4%. With stringent patient selection and utilization of enhanced recovery pathways, our study indicates that SG may be suitable for the outpatient setting. Experience and comfort with bariatric surgery is essential on the part of the operating surgeon to ensure good outcomes. Our low overall readmission and complication rate portends to the feasibility of laparoscopic SG as a safe outpatient procedure. Copyright © 2018 American Society for Bariatric Surgery.

Compared with conventional pharmacological therapies, bariatric surgery has been shown to cause greater and- sustained weight loss. It was aimed to evaluate weight loss in obese patients after laparoscopic adjustable gastric banding surgery using information typically available during the initial evaluation studied before bariatric surgery and genes. 74 patients undergoing laparoscopic adjustable gastric banding (LAGB) were enrolled. Artificial Neural Network technology was used to predict weight loss. We studied 74 patients consisting of 22 men and 52 women 2 years after operation. Mean age was 31.7 +/- 9.1 years. 27 (36.5%) patients had successful weight reduction (excess weight loss >50%) while 47 (63.5%) did not. ANN provided predicted factors on gender, insulin, albumin and two genes: re4684846_r, rs660339_r which were associated with success. Artificial neural network is a better modeling technique and the predictive accuracy is higher on the basis of multiple variables related to laboratory tests. Our finding gave demonstrated result that obese patients of successful weight reduction after laparoscopic adjustable gastric banding surgery were women, having little lower insulin and albumin, and carrying GG genotype on rs4684846 and with at least one T allele on rs660339. In these cases, weight loss will give better results.

Summary Background Achalasia is a not frequent esophageal disorder characterized by the absence of esophageal peristalsis and incomplete relaxation of the lower esophageal sphincter (LES). Its cause is unknown. The aim of treatment is to improve the symptoms. We report the results of the treatment of this condition achieved in one center. Patients and methods We conducted a retrospective study of patients with esophageal achalasia. In the period 2010–2012 we observed 64 patients, of whom 19 were referred for medical treatment. Three of the remaining patients underwent botulinum toxin injection, 17 underwent multiple endoscopic dilation procedures and 25 underwent laparoscopic surgery. Results There were no complications in the group undergoing endoscopic therapy, but symptom remission was only temporary. Patients undergoing surgery showed a significant improvement in symptoms and no recurrence throughout the follow-up period, that is still ongoing (3 years). There were no major complications in any case and no morbidity or mortality. Conclusions Surgical treatment of esophageal achalasia with laparoscopic Heller myotomy and Dor fundoplication gives the best and longest-lasting results in suitably selected patients. The extension of the myotomy and reduction in LES pressure are the most important parameters to achieve a good result. PMID:24091178

To evaluate the effects of gum chewing combined with a semi-liquid diet on patients after gynaecologic laparoscopic surgery. Previous studies suggested that chewing gum before traditional postoperative care promotes the postoperative recovery of bowel motility and function after open and laparoscopic surgery. However, gum chewing combined with a semi-liquid diet has not been reported in postoperative care of patients following gynaecologic laparoscopic surgery. A prospective randomised study. Total 234 patients were randomly assigned after elective gynaecologic laparoscopic surgery to a gum chewing and semi-liquid diet group, a semi-liquid only diet group or a liquid diet group. The gum chewing and semi-liquid diet group chewed sugar-free gum with an oral intake of a semi-liquid diet six hours postoperatively. The semi-liquid only diet and liquid diet groups received a semi-liquid diet or a liquid diet, respectively. The time to first bowel sounds, time to first regular postoperative bowel sounds, time to first passage of flatus, time to first defecation, serum gastrin and incidences of hunger, nausea, vomiting and abdominal distension were recorded. Hunger and gastrointestinal sensations were assessed using a four-point scale. Serum gastrin was assayed pre- and postoperatively using a gastrin radioimmunoassay kit. The gum chewing and semi-liquid diet group had first bowel sounds, first regular bowel sounds, first passage of flatus and first defecation earlier than the semi-liquid only and liquid groups. Increased serum gastrin was observed in the gum chewing and semi-liquid diet group. Incidences of nausea, vomiting and abdominal distention were not significantly different between these groups. Chewing gum combined with an oral intake of a semi-liquid diet is safe and accelerates the postoperative recovery of bowel function. It might be recommended as a better postoperative care regimen for patients after gynaecologic laparoscopic surgery. This study developed a new postoperative diet regimen to improve the postoperative care of patients undergoing laparoscopic gynecologic surgery. © 2016 John Wiley & Sons Ltd.

To evaluate postoperative health resource utilisation and secondary care costs for radical prostatectomy and partial nephrectomy in National Health Service (NHS) hospitals in England, via a comparison of robot-assisted, conventional laparoscopic and open surgical approaches. We retrospectively analysed the secondary care records of 23 735 patients who underwent robot-assisted (RARP, n = 8 016), laparoscopic (LRP, n = 6 776) or open radical prostatectomy (ORP, n = 8 943). We further analysed 2 173 patients who underwent robot-assisted (RAPN, n = 365), laparoscopic (LPN, n = 792) or open partial nephrectomy (OPN, n = 1 016). Postoperative inpatient admissions, hospital bed-days, excess bed-days and outpatient appointments at 360 and 1 080 days after surgery were reviewed. Patients in the RARP group required significantly fewer inpatient admissions, hospital bed-days and excess bed-days at 360 and 1 080 days than patients undergoing ORP. Patients undergoing ORP had a significantly higher number of outpatient appointments at 1 080 days. The corresponding total costs were significantly lower for patients in the RARP group at 360 days (£1679 vs £2031 for ORP; P < 0.001) and at 1 080 days (£3461 vs £4208 for ORP; P < 0.001). In partial nephrectomy, Patients in the RAPN group required significantly fewer inpatient admissions and hospital bed-days at 360 days compared with those in the OPN group; no significant differences were observed in outcomes at 1 080 days. The corresponding total costs were lower for patients in the RAPN group at 360 days (£779 vs £1242 for OPN, P = 0.843) and at 1 080 days (£2122 vs £2889 for ORP; P = 0.570). For both procedure types, resource utilisation and costs for laparoscopic surgeries lay at the approximate midpoint of those for robot-assisted and open surgeries. Our analysis provides compelling evidence to suggest that RARP leads to reduced long-term health resource utilisation and downstream cost savings compared with traditional open and laparoscopic approaches. Furthermore, despite the limitations that arise from the inclusion of a small sample, these results also suggest that robot-assisted surgery may represent a cost-saving alternative to existing surgical options in partial nephrectomy. Further exploration of clinical cost drivers, as well as an extension of the analysis into subsequent years, could lend support to the wider commissioning of robot-assisted surgery within the NHS. © 2015 The Authors BJU International © 2015 BJU International Published by John Wiley & Sons Ltd.

The effect of antiplatelet therapy (APT) on surgical blood loss and perioperative complications in patients receiving abdominal laparoscopic surgery still remains unclear. A total of 1,075 consecutive patients undergoing abdominal laparoscopic surgery between 2005 and 2011 were reviewed. Our perioperative management protocol consisted of interruption of APT 1 week before surgery and early postoperative reinstitution in low thromboembolic risk patients (n = 160, iAPT group). Preoperative APT was maintained in patients with high thromboembolic risk or emergent situation (n = 52, cAPT group). Perioperative and outcomes variables of cAPT and iAPT groups, including bleeding and thromboembolic complications, were compared with those of patients without APT (non-APT group, n = 863). In this cohort, 715 basic and 360 advanced laparoscopic operations were included. No patient suffering excessive intraoperative bleeding due to continuation of APT was observed. There were 10 postoperative bleeding complications (0.9%) and 3 thromboembolic events (0.3%), but the surgery was free of both complications in the cAPT group. No significant differences were found between the groups in operative blood loss, blood transfusion rate, and the occurrence of bleeding and thromboembolic complications. Multivariable analyses showed that multiple antiplatelet agents (p = 0.015) and intraoperative blood transfusion (p = 0.046) were significant prognostic factors for postoperative bleeding complications. Increased thromboembolic complications were independently associated with high New York Heart Association class (p = 0.019) and history of cerebral infarction (p = 0.048), but not associated with APT use. Abdominal laparoscopic operations were successfully performed without any increase in severe complications in patients with APT compared with the non-APT group under our rigorous perioperative assessment and management. Maintenance of single APT should be considered in patients with high thromboembolic risk, even when an abdominal laparoscopic approach is considered. Copyright © 2013 American College of Surgeons.

To evaluate the effect of pre-operative indomethacin suppository on postoperative nausea and vomiting in patients undergoing laparoscopic cholecystectomy. A double blind placebo-controlled randomized clinical trial. Hazrat Rasoul Akram Hospital, Tehran, Iran, from February 2010 to September 2012. One hundred and thirty patients, scheduled for laparoscopic cholecystectomy, were randomly divided into case and control groups. Sixty-five patients received indomethacin suppository and 70 patients received rectal placebo in the case and control groups respectively. All patients underwent the same protocol in laparoscopic surgery and anesthesia, then nausea and vomiting was recorded after 1, 6, 12 and 24 hours postoperatively and compared between the two groups. Independent-sample t test or Mann-Whitney tests were used for statistical analysis. Level of statistical significance was set at P ² 0.05. Patients' nausea was statistically lower in the case group at the 1st hour (43.1 vs. 92.9%), 6th hour (20.0 vs. 68.6%) and 12th hour (7.7 vs. 24.3%) after surgery (for all periods, P < 0.001). Fewer patients in the case group experienced vomiting at the first (13.8 vs. 51.4%) and 6th hour (0 vs. 20%) after surgery (for both P < 0.001). The use of pethidine was also statistically less in the case group in the same hours after surgery (for all of them, P < 0.001). Rectal indomethacin before laparoscopic cholecystectomy led to lower postoperative nausea and vomiting.

Colovesical fistulas originating from complicated sigmoid diverticular disease are rare. The primary aim of this review was to evaluate the role of laparoscopic surgery in the treatment of this complication. The secondary aim was to determine the best surgical treatment for this disease. A systematic search was conducted for studies published between 1992 and 2012 in PubMed, the Cochrane Register of Controlled Clinical Trials, Scopus, and Publish or Perish. Studies enrolling adults undergoing fully laparoscopic, laparoscopic-assisted, or hand-assisted laparoscopic surgery for colovesical fistula secondary to complicated sigmoid diverticular disease were considered. Data extracted concerned the surgical technique, intraoperative outcomes, and postoperative outcomes based on the Cochrane Consumers and Communication Review Group's template. Descriptive statistics were reported according to the PRISMA statement. In all, 202 patients from 25 studies were included in this review. The standard treatment was laparoscopic colonic resection and primary anastomosis or temporary colostomy with or without resection of the bladder wall. Operative time ranged from 150 to 321 min. It was not possible to evaluate the conversion rate to open surgery because colovesical fistulas were not distinguished from other types of enteric fistulas in most of the studies. One anastomotic leak after bowel anastomosis was reported. There was zero mortality. Few studies conducted follow-up longer than 12 months. One patient required two reoperations. Laparoscopic treatment of colovesical fistulas secondary to sigmoid diverticular disease appears to be a feasible and safe approach. However, further studies are needed to establish whether laparoscopy is preferable to other surgical approaches.

The reported incidence of acute chest syndrome (ACS) in children with sickle cell disease (SCD) is 15% to 20%. Our current objective was to assess risk factors and morbidity associated with ACS. The authors reviewed the outcome of children with SCD undergoing abdominal surgery over a 10-year period. From 1991 to 2003, 60 children underwent laparoscopic cholecystectomy (LC; n = 29), laparoscopic splenectomy (LS; n = 28), or both (LB; n = 3). Mean age was 8.6 (0.7 to 20) years, and 35 (58%) were boys. Fifty-four (90%) had a preoperative hemoglobin greater than 10 g/dL, but only 22 (37%) received routine oxygen after surgery. No surgery was converted to an open procedure. Four children (6.6%), all of whom underwent either LS or LB, had ACS associated with an increased length of stay (7.4 +/- 2.4 days) but no mortality. Factors associated with the development of ACS were age (3.0 +/- 1.7 v 9.4 +/- 5.7 years; P =.03), weight (12.1 +/- 3.0 v 32.6 +/- 18.2 kg; P =.04), operative blood loss (3.2 +/- 0.5 v 1.4 +/- 1.2 mL/kg; P =.03), and final temperature in the operating room (OR; 36.2 +/- 0.4 v 37.6 +/- 0.4 degrees C; P =.01). ACS was not significantly related to duration of surgery, OR fluids, or oxygen usage. Younger children with greater blood and heat loss during surgery appear more prone to ACS. Splenectomy also seems to increase the risk of ACS. The authors' current incidence (6.6%) of ACS in children with SCD undergoing abdominal surgery is much lower than previously reported. This may be explained by the aggressive use of preoperative blood transfusion or more routine use of laparoscopy.

Image-guided fiducial markers are being used in surgery, especially in spine and breast surgery, and radiotherapy, allowing localization of tumor sites precisely. We report a case of fiducial coil use in a man undergoing a robot-assisted laparoscopic resection of a metastatic nodule under the ipsilateral diaphragm after robot-assisted partial nephrectomy performed 2 years ago for a left upper pole renal tumor. The fiducial coil facilitated the localization of the lesion, which would otherwise have been challenging because of its small size and location. In addition, the fiducial coil was helpful to avoid cutting into the lesion directly. Copyright © 2014 Elsevier Inc. All rights reserved.

Low-dose haloperidol is known to be effective for the prevention of postoperative nausea and vomiting (PONV). However, precise dose-response studies have not been completed, especially in patients at high risk for PONV who require combination therapy. This study sought to identify which dose of haloperidol 1mg or 2mg could be combined with dexamethasone without adverse effects in high-risk patients undergoing gynecological laparoscopic surgery. Female adults (n = 150) with three established PONV risk factors based on Apfel's score were randomized into one of three study groups. At the end of anesthesia, groups H0, H1, and H2 were given intravenous (IV) saline, haloperidol 1 mg, and haloperidol 2 mg, respectively. All patients were given dexamethasone 5 mg during the induction of anesthesia. The overall early (0-2 h) and late (2-24 h) incidences of nausea, vomiting, rescue anti-emetic administration, pain, and adverse effects (cardiac arrhythmias and extrapyramidal effects) were assessed postoperatively. The sedation score was recorded in the postanesthesia care unit (PACU). The total incidence of PONV over 24 h was significantly lower in groups H1 (29 %) and H2 (24 %) than in group H0 (54 %; P = 0.003), but there was no significant difference between groups H1 and H2. In the PACU, group H2 had a higher sedation score than groups H1 and H0 (P < 0.001). For high-risk PONV patients undergoing gynecological laparoscopic surgery, when used with dexamethasone, 1-mg haloperidol was equally effective as 2 mg in terms of preventing PONV with the less sedative effect.

The laparoscopic cholecystectomy (LC) is the gold standard to treat gallstone. To view the surgical site in this type of operations better, carbon dioxide is used with a certain pressure. The current study aimed to compare the hemodynamic symptoms and the level of abdominal pain due to using high- and low-pressure carbon dioxide in patients undergoing LC. The current double-blind randomized clinical trial was conducted on 60 patients with the age range of 20-70 years old undergoing LC. The first and second groups experienced PaCO 2 of 7-10 and 12-14 mmHg, respectively. The hemodynamic symptoms, abdominal pain, shoulder-tip pain, nausea and vomiting after the surgery, and the mean of liver function tests were evaluated. Data were analyzed using T test, Chi-square test, and repeated measures ANOVA by SPSS 16. Information of 60 patients in two groups was analyzed. There was a significant difference between the groups regarding the mean of systolic blood pressure ( P  < 0.05). The mean of heart rate was significantly higher in the high-pressure group during surgery and 1 h after that ( P  < 0.05). The frequency of pain in shoulder-tip and abdomen was higher in the high-pressure group. Frequency of nausea and vomiting 12 h after the surgery between two groups was significant ( P  < 0.05). The mean of alkaline phosphatase was higher in the low-pressure group than the high-pressure group ( P  < 0.05). Considering the good performance and low side effects of low-pressure laparoscopic cholecystectomy compared to those of high-pressure, this method can be replaced by high-pressure in LC.

Heller Myotomy for Achalasia: Quality of Life Comparison of Laparoscopic and Open Approaches

Katilius, Marius

2001-01-01

Background: Achalasia is a relatively rare disorder with a variety of treatment options. Although laparoscopic Heller myotomy has become the surgical treatment of choice, little data exist on the overall quality of life of patients undergoing this technique versus standard open approaches. Methods: We prospectively evaluated all patients surgically treated for achalasia by a single surgeon. Laparoscopic Heller myotomy consisted of a long (≥ 6 cm) esophageal cardiomyotomy extending at least 2 cm onto the gastric cardia, with a concomitant Dor fundoplication. Patients were evaluated preoperatively and postoperatively for symptoms and quality of life using the SF-36, a standardized, generic quality of life instrument. Results: A total of 23 patients were surgically treated: 15 patients had a planned laparoscopic procedure, with 3 conversions; 8 had planned open procedures. Dysphagia resolved in 20 of 21 patients, with 1 patient in the laparoscopic group requiring reoperation due to an inadequate gastric myotomy. Compared with preoperative scores, a statistically significant improvement occurred in the general health domain of the SF-36 (70 to 82, P = 0.04). Compared with that in patients undergoing open surgery, the laparoscopic group had better scores in the domains of physical functioning and bodily pain. Conclusions: Laparoscopic Heller myotomy has comparable success to open Heller myotomy, and causes less early detriment to quality of life. This should be the primary treatment in all fit surgical patients with achalasia. PMID:11548827

Background: The popularity of single-incision procedures is on the rise as wound cosmesis is increasingly being seen as an important body image-related outcome. In this study, we assess the potential benefits of single-incision multiport laparoscopic totally extra-peritoneal (S-TEP) without using specialised ports or instruments and compare the same with the conventional laparoscopic TEP (C-TEP) surgery in terms of operative time, post-operative pain, complications, cost and cosmesis. Materials and Methods: This is a prospective case-matched study of the patients undergoing S-TEP versus C-TEP from June 2014 to December 2015. Results: Each group had 36 patients. The two groups were comparable in the clinical characteristics. The mean duration of surgery for a unilateral hernia in C-TEP and S-TEP was 45.13 ± 10.58 min and 72.63 ± 15.23 min, respectively. The mean visual analogue scale (VAS) score for pain was significantly higher in S-TEP group at post-operative day (POD) 0 and 1. However, at POD 7, there was no significant difference between the groups. At 1st and 6-week post-surgery, the cosmetic results were significantly better in S-TEP group as compared to C-TEP, however, at 6 months, the scar was highly acceptable in both treatment groups. Conclusion: S-TEP, using conventional laparoscopic instruments, is safe and feasible even in resource challenged setting. However, there is a need to review the indications and advantages of single-incision laparoscopic surgery, as no difference in cosmetic outcome by VAS score in S-TEP versus conventional laparoscopic arm seen by the end of 1 month.

AIM: To investigate the effect of pain relief after infusion of ropivacaine at port sites at the end of surgery. METHODS: From October 2006 to September 2007, 72 patients undergoing laparoscopic cholecystectomy (LC) were randomized into two groups of 36 patients. One group received ropivacaine infusion at the port sites at the end of LC and the other received normal saline. A visual analog scale was used to assess postoperative pain when the patient awakened in the operating room, 6 and 24 h after surgery, and before discharge. The amount of analgesics use was also recorded. The demographics, laboratory data, hospital stay, and perioperative complications were compared between the two groups. RESULTS: There was no difference between the two groups preoperatively in terms of demographic and laboratory data. After surgery, similar operation time, blood loss, and no postoperative morbidity and mortality were observed in the two groups. However, a significantly lower pain score was observed in the patients undergoing LC with local anesthesia infusion at 1 h after LC and at discharge. Regarding analgesic use, the amount of meperidine used 1 h after LC and the total used during admission were lower in patients undergoing LC with local anesthesia infusion. This group also had a shorter hospital stay. CONCLUSION: Local anesthesia with ropivacaine at the port site in LC patients significantly decreased postoperative pain immediately. This explains the lower meperidine use and earlier discharge for these patients. PMID:19452582

Surgical management of benign and indeterminate hepatic lesions in the era of laparoscopic liver surgery.

2011-01-01

The expansion of the laparoscopic approach for the management of benign liver lesions has raised concerns regarding the risk of widening surgical indications and compromising safety. Large single-centre series focusing on laparoscopic management of benign liver lesions are sporadic. We reviewed a prospectively collected database of patients undergoing pure laparoscopic liver resection (LLR) for benign liver lesions. All cases were individually discussed at a multidisciplinary team meeting. Forty-six patients underwent 50 LLRs for benign disease. Indications for surgery were: symptomatic lesions, preoperative diagnosis of adenoma or cystadenoma, and lesions with an indeterminate diagnosis. The preoperative diagnosis was uncertain in 11 cases. Of these, histological diagnosis was hepatocellular carcinoma in one (9%) and benign lesion in 10 patients (91%). Thirteen patients (28%) required major hepatectomy. Three patients (7%) developed postoperative complications. Mortality was nil. The median postoperative hospital stay following major and minor hepatectomy was 4 and 3 days, respectively. The laparoscopic approach represents a safe option for the management of benign and indeterminate liver lesions, even when major hepatectomy is required. LLR should be only performed in specialized centres to ensure safety and strict adherence to orthodox surgical indication. Copyright © 2011 S. Karger AG, Basel.

Despite the laparoscopic right hemicolectomy has been validated by many randomized prospective trials, clear evidences on the validity of the totally mini-invasive technique, namely, through intracorporeal anastomosis, are still lacking. The aim of this study was the assessment of short-term outcome within three months from laparoscopic right colectomy with intra- or extra-corporeal anastomosis. With no exclusion, all patients undergoing laparoscopic right hemicolectomy at our institution have been enrolled in this study. Group A included patients undergoing laparoscopic right hemicolectomy with extracorporeal anastomosis (LAC) and Group B, included patients undergoing laparoscopic right hemicolectomy with intracorporeal anastomosis (TLC). Patients' data, surgery details, results of postoperative period and histological tests have been prospectively recorded in a database and analysed. Between December 2006 and December 2008, 45 patients underwent right hemicolectomy, 21 with extracorporeal anastomosis and 24 had intracorporeal ones. As to patients' characteristics and histopathological results there are no difference between the groups. Anastomotic dehiscence occurred one in group A and one in group B (P>0.05). Both patients underwent reoperation. We recorded 6 postoperative ileus with vomiting in the LAC group and only 1 in the TLC group (P<0.05). The incidence of Non-Surgical Site Complications (NSSC) was of 4.54% in LAC group and 8.33% in TLC group (P>0.05). Hospitalization was of 5 days for both groups. In conclusion, we believe that this technique is feasible in terms of safety; it doesn't significatively affect the length of surgical procedure and guarantees maintenance of oncological radicality standards of reference. Besides it significatively improves quality of the post-operative period.

To share our experience regarding the laparoscopic Frey procedure for chronic pancreatitis (CP) and patient selection. All consecutive patients undergoing duodenum-preserving pancreatic head resection from July 2013 to July 2014 were reviewed and those undergoing the Frey procedure for CP were included in this study. Data on age, gender, body mass index (BMI), American Society of Anesthesiologists score, imaging findings, inflammatory index (white blood cells, interleukin (IL)-6, and C-reaction protein), visual analogue score score during hospitalization and outpatient visit, history of CP, operative time, estimated blood loss, and postoperative data (postoperative mortality and morbidity, postoperative length of hospital stay) were obtained for patients undergoing laparoscopic surgery. The open surgery cases in this study were analyzed for risk factors related to extensive bleeding, which was the major reason for conversion during the laparoscopic procedure. Age, gender, etiology, imaging findings, amylase level, complications due to pancreatitis, functional insufficiency, and history of CP were assessed in these patients. Nine laparoscopic and 37 open Frey procedures were analyzed. Of the 46 patients, 39 were male (85%) and seven were female (16%). The etiology of CP was alcohol in 32 patients (70%) and idiopathic in 14 patients (30%). Stones were found in 38 patients (83%). An inflammatory mass was found in five patients (11%). The time from diagnosis of CP to the Frey procedure was 39 ± 19 (9-85) mo. The BMI of patients in the laparoscopic group was 20.4 ± 1.7 (17.8-22.4) kg/m(2) and was 20.6 ± 2.9 (15.4-27.7) kg/m(2) in the open group. All patients required analgesic medication for abdominal pain. Frequent acute pancreatitis or severe abdominal pain due to acute exacerbation occurred in 20 patients (43%). Pre-operative complications due to pancreatitis were observed in 18 patients (39%). Pancreatic functional insufficiency was observed in 14 patients (30%). Two laparoscopic patients (2/9) were converted. In seven successful laparoscopic cases, the mean operative time was 323 ± 29 (290-370) min. Estimated intra-operative blood loss was 57 ± 14 (40-80) mL. One patient had a postoperative complication, and no mortality was observed. Postoperative hospital stay was 7 ± 2 (5-11) d. Multiple linear regression analysis of 37 open Frey procedures showed that an inflammatory mass (P < 0.001) and acute exacerbation (P < 0.001) were risk factors for intra-operative blood loss. The laparoscopic Frey procedure for CP is feasible but only suitable in carefully selected patients.

Objective: To review the physiologic effects of carbon dioxide (CO2) pneumoperitoneum in the morbidly obese. Summary Background Data: The number of laparoscopic bariatric operations performed in the United States has increased dramatically over the past several years. Laparoscopic bariatric surgery requires abdominal insufflation with CO2 and an increase in the intraabdominal pressure up to 15 mm Hg. Many studies have demonstrated the adverse consequences of pneumoperitoneum; however, few studies have examined the physiologic effects of pneumoperitoneum in the morbidly obese. Methods: A MEDLINE search from 1994 to 2003 was performed using the key words morbid obesity, laparoscopy, bariatric surgery, pneumoperitoneum, and gastric bypass. The authors reviewed papers evaluating the physiologic effects of pneumoperitoneum in morbidly obese subjects undergoing laparoscopy. The topics examined included alteration in acid-base balance, hemodynamics, femoral venous flow, and hepatic, renal, and cardiorespiratory function. Results: Physiologically, morbidly obese patients have a higher intraabdominal pressure at 2 to 3 times that of nonobese patients. The adverse consequences of pneumoperitoneum in morbidly obese patients are similar to those observed in nonobese patients. Laparoscopy in the obese can lead to systemic absorption of CO2 and increased requirements for CO2 elimination. The increased intraabdominal pressure enhances venous stasis, reduces intraoperative portal venous blood flow, decreases intraoperative urinary output, lowers respiratory compliance, increases airway pressure, and impairs cardiac function. Intraoperative management to minimize the adverse changes include appropriate ventilatory adjustments to avoid hypercapnia and acidosis, the use of sequential compression devices to minimizes venous stasis, and optimize intravascular volume to minimize the effects of increased intraabdominal pressure on renal and cardiac function. Conclusions: Morbidly obese patients undergoing laparoscopic bariatric surgery are at risk for intraoperative complications relating to the use of CO2 pneumoperitoneum. Surgeons performing laparoscopic bariatric surgery should understand the physiologic effects of CO2 pneumoperitoneum in the morbidly obese and make appropriate intraoperative adjustments to minimize the adverse changes.

Objective: To evaluate the efficacy of preemptive intravenous oxycodone in the patients undergoing laparoscopic resection of ovarian tumor. Methods: Sixty ASA I or II patients undergoing elective laparoscopic resection of ovarian tumor were randomly allocated to one of two groups: Group O (n=30) received intravenous oxycodone (0.1 mg·kg-1) 10 minutes before surgery over 2 minutes, and Group N (n=30) received an equivalent volume of normal saline. All patients received a standardized general anesthesia. MBP and HR at the time of arrival of the operating room (T1), 5 min before pneumoperitoneum (T2), 5 minutes (T3), 10 minutes (T4), and 15 minutes after pneumoperitoneum (T5), and VAS scores at postoperative 2, 4, 8, 12 and 24 hour were recorded. The tramadol consumption and side effects in 24 h after surgery were recorded. Results: VAS pain scores at 2, 4, 8 and 12 hour after operation were significantly lower in Group O (P<0.05). MBP and HR increased significantly due to pneumoperitoneum at T3, T4 and T5, compared with T1 and T2 within Group N, and were higher at T3, T4 and T5 in Group N than at the same time points in Group O. Tramadol consumption was statistically lower in Group O (P=0.0003). Conclusions: Preemptive intravenous oxycodone was an efficient and safe method to reduce intraoperative haemodynamic effect and postoperative pain. PMID:26101479

Major surgery is associated with postoperative insulin resistance which is attenuated by preoperative carbohydrate (CHO) treatment. The effect of this treatment on clinical outcome after major abdominal surgery has not been assessed in a double-blind randomized trial. Patients undergoing elective colorectal surgery or liver resection were randomized to oral CHO or placebo drinks to be taken on the evening before surgery and 2 h before induction of anaesthesia. Primary outcomes were postoperative length of hospital stay and fatigue measured by visual analogue scale. Sixty-nine and 73 patients were evaluated in the CHO and placebo groups respectively. The groups were well matched with respect to surgical procedure, epidural analgesia, laparoscopic procedures, fasting period before induction and duration of surgery. Postoperative changes in fatigue score from baseline did not differ between the groups. Median (range) hospital stay was 7 (2-35) days in the CHO group and 8 (2-92) days in the placebo group (P = 0.344). For patients not receiving epidural blockade or laparoscopic surgery (20 CHO, 19 placebo), values were 7 (3-11) and 9 (2-48) days respectively (P = 0.054). Preoperative CHO treatment did not improve postoperative fatigue or length of hospital stay after major abdominal surgery. A benefit is not ruled out when epidural blockade or laparoscopic procedures are not used. ACTRN012605000456651 (http://www.anzctr.org.au). Copyright (c) 2010 British Journal of Surgery Society Ltd.

An obesity surgery mortality risk score derived from a single clinical series can be used to stratify the mortality risk of patients undergoing gastric bypass. However, such a scoring system does not take into account 2 important factors in contemporary bariatric surgery--increased use of the laparoscopic approach and laparoscopic adjustable gastric banding. The present study analyzed the preoperative factors that might predict in-hospital mortality after bariatric surgery using data from academic medical centers and proposes a classification system for predicting mortality. Using the "International Classification of Diseases, 9th revision," diagnosis and procedural codes, the data for all patients who underwent bariatric surgery for the treatment of morbid obesity from 2002 to 2009 were obtained from the University HealthSystem Consortium database. The limitations of this database included the lack of the body mass index and the underestimation of some co-morbidities, such as sleep apnea. Multiple regression analyses were performed to determine the factors predictive of greater in-hospital mortality. The factors examined included race, gender, age, co-morbidities, surgical technique (laparoscopic versus open), bariatric operation (gastric bypass versus nongastric bypass), and payer type. A scoring system was devised by assigning 1 point for each major factor (those with an adjusted odds ratio [AOR] of ≥2.0) and .5 point for each minor factor (those with an AOR <2.0). Using contemporary data from 2007 to 2009, the in-hospital mortality was analyzed according to the classification: class I, 0-0.5 point; class II, 1.0-1.5 points; class III, 2.0-3.0 points; and class IV, ≥3.5 points. During the 8-year period, 105,287 patients underwent bariatric surgery. The operations included laparoscopic gastric bypass (45%), open gastric bypass (41%), and laparoscopic gastric banding or gastroplasty (14%). The overall in-hospital mortality rate was .17%. The number of deaths per 1000 bariatric operations decreased from 4.0 in 2002 to .6 in 2009. Using regression analyses, the factors predictive of greater in-hospital mortality were male gender (AOR 3.2), gastric bypass procedure (AOR 5.8), open surgical technique (AOR 4.8), Medicare payer (AOR 3.0), diabetes (AOR 1.6), and age >60 years (AOR 1.9). The mortality rate was .10% for class I patients, .15% for class II, .33% for class III, and .70% for class IV (P < .05 among all classes). Within the context of academic centers, the mortality after bariatric surgery has decreased substantially since 2002, with an increase in the use of the laparoscopic technique and laparoscopic gastric banding. A bariatric mortality risk classification system was developed to stratify mortality, given the limits of this database, which does not include the body mass index and underestimates the incidence of sleep apnea. It might be useful to aid surgeons in surgical decision-making, to inform patients of their risks, and for quality improvement reporting purposes.

To report an autograft of ovarian tissue in the incision of the surgical trocar during laparoscopic surgery and to assess the potentiality of grafting of ovarian parenchyma in nonpelvic tissue in humans. A case report. Instituto de Fertilidad y Ginecología de Buenos Aires (IFER), Buenos Aires, Argentina. Infertile patient undergoing surgery due to an endometriotic cyst of the left ovary. Laparoscopic cystectomy. Accidental retention of a portion of the capsule and adjacent ovarian tissue of the endometrioma in SC cellular tissue. Months after surgery, a SC tumor was formed under the surgical incision. It was subsequently excised. Observation of tumor growth during menstrual cycles and ovulation induction; anatomopathologic study of the tissue after its extirpation. The tumor grew spontaneously in the periovulatory period and during treatments of ovulation induction. The anatomopathologic report of the tumor, removed 15 months after the first surgery, revealed functioning ovarian tissue with vessels of neoformation. This is the first description of autografted ovarian tissue in humans. We describe that the ovary can maintain its ovulatory function even in the absence of its pedicel. Also, we suggest that extirpation of surgical material through the incision of the trocar is not recommended, as the possibility of "sowing" or of autografts may occur.

Patients undergoing gynecology laparoscopy frequently experience shoulder pain as a common postoperative complication. Considering diaphragm stimulation in its pathophysiology, there are some advice to prevent or control this special form of referral pain. The current study aimed to assess the prophylactic effect of preoperative administration of oral gabapentin to prevent Post Laparoscopic Shoulder Pain (PLSP) after laparoscopic ovarian cystectomy. In a randomized, double blind, placebo controlled trial 40 female patients who were candidates to have elective laparoscopic ovarian cystectomy, received uniformed capsules containing gabapentin 600 mg or placebo 30 minutes before anesthesia induction. All patients had the American Society of Anesthesiologists (ASA) Physical Status of I-II and none had pervious abdominal surgery. Thereafter, the presence of side effects and PLSP and its severity was assessed by Visual Analog Scale (VAS) in the beginning of surgery and 2, 6, 12 hours after the surgery. Comparing the gabapentin (n = 20) and placebo (n = 20) groups, basic characteristics including age (P = 0.446), Body Mass Index (BMI) (P = 0.876), pregnancy history (P = 0.660), and surgery time (P = 0.232) were statistically similar. PLSP occurrence was less frequent in the gabapentin group (45%) compared with the placebo group (75%) (P = 0.053), while In gabapentin group the VAS scores were lower in 2(P = 0.004), 6 (P = 0.132), and 12 (P = 0.036) hours, post operatively. Prophylactic gabapentin administration could be considered as an effective and safe intervention to reduce occurrence and severity of PLSP after gynecologic laparoscopic cystectomy.

Lam, Alan M.; Carlton, Mark A.; Cario, Gregory M.; McBride, Lindsay

1998-01-01

Background and Objectives: To compare the use of patient-controlled analgesia to intermittent intramuscular injections of morphine following major gynecological laparoscopic procedures in order to assess differences in level of pain, sedation, episodes of nausea and/or vomiting, hospitalization time and patient satisfaction with their postoperative analgesia. Methods: Seventy-two patients undergoing major gynecological laparoscopic surgery were randomized to receive either postoperative analgesia via intermittent intramuscular injection of morphine (Group 1) or patient controlled analgesia (PCA - Group 2). All patients received anesthesia via a standardized protocol. Postoperative pain levels were recorded via a 10 cm visual analogue scale, and sedation scores were recorded on a standard PCA form. Episodes of nausea and vomiting were also recorded on the same form. Results: There were no statistically significant differences between intramuscular analgesia and PCA for any of the factors studied. Most significantly it was found that most patients ceased to require either form of parenteral analgesia within 24 hours of their procedure, regardless of the operating time. Conclusion: It is important for the surgeon to be aware of the effects of postoperative analgesia on his or her patients' level of satisfaction. We do not recommend the use of PCA analgesia following major laparoscopic gynecological surgery. PMID:9876706

Laparoscopic surgery for colon cancer: a review of the fascial composition of the abdominal cavity.

PubMed

Mike, Makio; Kano, Nobuyasu

2015-02-01

Laparoscopic surgery has generally been performed for digestive diseases. Many patients with colon cancer undergo laparoscopic procedures. The outcomes of laparoscopic colectomy and open colectomy are the same in terms of the long-time survival. It is important to dissect the embryological plane to harvest the lymph nodes and to avoid bleeding during colon cancer surgery. To date, descriptions of the anatomy of the fascial composition have mainly involved observations unrelated to fundamental embryological concepts, causing confusion regarding the explanations of the surgical procedures, with various vocabularies used without definitions. We therefore examined the fascia of the abdominal space using a fascia concept based on clinical anatomy and embryology. Mobilization of the bilateral sides of the colon involves dissection between the fusion fascia of Toldt and the deep subperitoneal fascia. It is important to understand that the right fusion fascia of Toldt is divided into the posterior pancreatic fascia of Treitz dorsally and the anterior pancreatic fascia ventrally at the second portion of the duodenum. A comprehensive understanding of fascia composition between the stomach and transverse colon is necessary for dissecting the splenic flexure of the colon. As a result of these considerations of the fascia, more accurate surgical procedures can be performed for the excision of colon cancer.

Extremely obese adolescents are increasingly undergoing bariatric procedures, which restrict dietary intake. However, as yet, no data are available describing the change in caloric density or composition of the adolescent bariatric patient's diet pre- and postoperatively. Our objective was to assess the 1-year change in the dietary composition of adolescents undergoing bariatric surgery at a tertiary care children's hospital. A total of 27 subjects (67% female, 77% white, age 16.7 ± 1.4 yr, baseline body mass index 60.1 ± 14.1 kg/m(2)) were prospectively enrolled into an observational cohort study 1 month before undergoing laparoscopic Roux-en-Y gastric bypass from August 2005 to March 2008. The 3-day dietary intake was recorded at baseline (n = 24) and 2 weeks (n = 16), 3 months (n = 11), and 1 year (n = 9) postoperatively. The dietary record data were verified by structured interview and compared with the Dietary Reference Intake values for ages 14-18 years. By 1 year after surgery, the mean caloric intake, adjusted for body mass index was 1015 ± 182 kcal/d, a 35% reduction from baseline. The proportion of fat, protein, and carbohydrate intake did not differ from baseline. However, the protein intake was lower than recommended postoperatively. The calcium and fiber intake was also persistently lower than recommended. Calcium and vitamin B(12) supplementation increased the likelihood of meeting the daily minimal recommendations (P ≤ .02). At 1 year after Roux-en-Y gastric bypass, the adolescents' caloric intake remained restricted, with satisfactory macronutrient composition but a lower than desirable intake of calcium, fiber, and protein.

Selective 5-hydroxytryptamine type 3 (5-HT3) receptor antagonists are reported to have potent antiemetic effects for postoperative nausea and vomiting (PONV). The purpose of this study was to prospectively evaluate the efficacy of palonosetron, granisetron, and ramosetron for the prevention of PONV in patients undergoing laparoscopic gynecologic surgery. In this prospective, randomized observational study, 105 healthy female patients who were undergoing laparocopic hystectomy under general anaesthesia were enrolled (clinical trial number: NCT01752374, www.clinicaltrials.gov ). Patients were divided into three groups: the palonostron (0.075 mg i.v.; n = 35), the granisetron group (3 mg i.v.; n = 35), and the ramosetron group (0.3 mg i.v.; n = 35). The treatments were given before the end of surgery. The incidence of PONV, severity of nausea/vomiting, and the use of rescue antiemetic requirements during the first 48 h after surgery were evaluated. The overall incidence of PONV was 33.3 % for this series. The number of complete responders at 48 h after the surgery was 21 (60.0 %) for palonosetron, 24 (68.6 %) for granisetron, and 26 (71.4 %) for ramosetron, representing no statistical difference (P = 0.086). There were no significant differences in the overall incidence of postoperative nausea and vomiting and complete responders for palonosetron, granisetron and ramosetron group.

Robotic technological aids in esophageal surgery.

PubMed

Rebecchi, Fabrizio; Allaix, Marco E; Morino, Mario

2017-01-01

Robotic technology is an emerging technology that has been developed in order to overcome some limitations of the standard laparoscopic approach, offering a stereoscopic three-dimensional visualization of the surgical field, increased maneuverability of the surgical tools with consequent increased movement accuracy and precision and improved ergonomics. It has been used for the surgical treatment of most benign esophageal disorders. More recently, it has been proposed also for patients with operable esophageal cancer. The current evidence shows that there are no real benefits of the robotic technology over conventional laparoscopy in patients undergoing a fundoplication for gastroesophageal reflux disease (GERD), hiatal closure for giant hiatal hernia, or Heller myotomy for achalasia. A few small studies suggest potential advantages in patients undergoing redo surgery for failed fundoplication or Heller myotomy, but large comparative studies are needed to better clarify the role of the robotic technology in these patients. Robot-assisted esophagectomy seems to be safe and effective in selected patients; however, there are no data showing superiority of this approach over both conventional laparoscopic and open surgery. The short-term and long-term oncologic results of ongoing randomized controlled trials (RCTs) are awaited to validate this approach for the treatment of esophageal cancer.

2015-01-01

As bariatric surgery rates continue to climb, anaemia will become an increasing concern. We assessed the prevalence of anaemia and length of hospital stay in patients undergoing bariatric surgery. Prospective data (anaemia [haemoglobin <12 g/dL], haematinics and length of hospital stay) was analysed on 400 hundred patients undergoing elective laparoscopic bariatric surgery. Results from a prospective database of 1530 patients undergoing elective general surgery were used as a baseline. Fifty-seven patients (14%) were anaemic pre-operatively, of which 98% were females. Median MCV (fL) and overall median ferritin (μg/L) was lower in anaemic patients (83 vs. 86, p=0.001) and (28 vs. 61, p<0.0001) respectively. In the elective general surgery patients, prevalence of anaemia was similar (14% vs. 16%) but absolute iron deficiency was more common in those undergoing bariatric surgery; microcytosis p<0.0001, ferritin <30 p<0.0001. Mean length of stay (days) was increased in the anaemic compared to in the non-anaemic group (2.7 vs. 1.9) and patients who were anaemic immediately post-operatively, also had an increased length of stay (2.7 vs. 1.9), p<0.05. Absolute iron deficiency was more common in patients undergoing bariatric surgery. In bariatric patients with anaemia there was an overall increased length of hospital stay.

The degree of neuromuscular blockade is one of the important factors that determine the condition of surgical space during laparoscopic surgery. Magnesium sulfate potentiates the actions of neuromuscular blocking agent, and we hypothesized that intraoperative magnesium sulfate infusion may improve surgical space condition during laparoscopic surgery. Eighty-four patients undergoing elective laparoscopic gastrectomy were randomized to receive isotonic saline (group C) or magnesium sulfate (group M, loading dose with 50 mg/kg over 10 min and then 15 mg/kg/h by continuous infusion) to maintain the moderate neuromuscular blockade using rocuronium. Two experienced surgeons scored the quality of surgical space condition using a 5-point surgical rating scale (SRS). The secondary outcomes included recovery profiles, postoperative pain and adverse events. The SRS in group M was higher than that of group C. The proportion of patients with a SRS of 5 (optimal) was 2.7 % in the group C and 40.5 % in the group M (P < 0.0001) although a lower amount of rocuronium was required in group M than group C [24.2 (6.5) mg/h for group M vs. 27.5 (6) mg/h for group C; P = 0.017]. Pain after operation site was less severe in group M than in group C at postoperative 24 h (P = 0.009). Recovery profiles and adverse events were similar between the two groups. Intraoperative administration of magnesium sulfate improved the quality of surgical space conditions and decreased neuromuscular blocking agent requirement and postoperative pain in patients undergoing laparoscopic gastrectomy.

The value of laparoscopic procedures has increased over the last decade. Many patients undergoing laparoscopic surgery also have coexisting diseases. The hemodynamic effects of intraperitoneal carbon dioxide insufflation depend on the extent of intraperitoneal pressure, severity of preexisting cardiopulmonary diseases, volume state of the patient and alterations of acid-base balance due to a capnoperitoneum. In addition to endocrinologic reactions, patient positioning also affects hemodynamic parameters. In high risk patients extended cardiopulmonary monitoring with an arterial line and repeated blood gas analysis is recommended intraoperatively, in addition to assessment of end-expiratory CO(2). In this patient group the intra-abdominal pressure should be maintained in the range of 5-7 mmHg.

Multimodal analgesic strategies are recommended to decrease opioid requirements and opioid-induced respiratory complications in patients undergoing laparoscopic bariatric surgery. Recent studies have demonstrated that intravenous ibuprofen decreases opioid consumption compared with placebo. The primary aim of this study was to compare the effect of intravenous ibuprofen and intravenous acetaminophen on opioid consumption. We also aimed to compare postoperative pain levels and side effects of the drugs. Randomized, double-blinded study. University hospital. Eighty patients, aged 18-65 years, (ASA physical status II-III) undergoing laparoscopic sleeve gastrectomy or laparoscopic Roux-en-Y gastric bypass surgery were included in this study. Patients were randomized to receive 800 mg ibuprofen or 1 g acetaminophen intravenously every 6 h for the first 24 h following surgery; in addition, patient-controlled analgesia with morphine was administered. Postoperative morphine consumption in the first 24 h, visual analog scale (VAS) pain scores at rest and with movement, and opioid related side effects were assessed. In addition, time to passage of flatus, surgical complications, lengths of intensive care unit and hospital stay, and laboratory parameters were recorded. The mean morphine consumption was 23.94 ± 13.89 mg in iv ibuprofen group and 30.23 ± 13.76 mg in the acetaminophen group [mean difference: -6.28 (95% CI, -12.70, 0.12); P = 0.055]. The use of intravenous ibuprofen was associated with reduction in pain at rest (AUC, 1- to 24-h, P < 0.001 and 12- to 24-h, P = 0.021) and pain with movement (AUC, 1-24, 6-24, and 12-24 h, P < 0.001). Intravenous ibuprofen was well tolerated with no serious side effects except dizziness. Intravenous ibuprofen did not significantly reduce opioid consumption compared to intravenous acetaminophen; however, it reduced the severity of pain. Intravenous ibuprofen may be a good alternative to intravenous acetaminophen as part of a multimodal postoperative analgesia in patients undergoing bariatric surgery. Copyright © 2018.

Radical retropubic prostatectomy (RRP) performed laparoscopically is a popular treatment with curative intent for organ-confined prostate cancer. After surgery, prostate specific antigen (PSA) levels drop to low levels which can be measured with ultrasensitive assays. This has been described in the literature for open RRP but not for laparoscopic RRP. This paper describes PSA changes in the first 300 consecutive patients undergoing non-robotic laparoscopic RRP by a single surgeon. To use ultrasensitive PSA (uPSA) assays to measure a PSA nadir in patients having laparoscopic radical prostatectomy below levels recorded by standard assays. The aim was to use uPSA nadir at 3 months' post-prostatectomy as an early surrogate end-point of oncological outcome. In so doing, laparoscopic oncological outcomes could then be compared with published results from other open radical prostatectomy series with similar end-points. Furthermore, this end-point could be used in the assessment of the surgeon's learning curve. Prospective, comprehensive, demographic, clinical, biochemical and operative data were collected from all patients undergoing non-robotic laparoscopic RRP. We present data from the first 300 consecutive patients undergoing laparoscopic RRP by a single surgeon. uPSA was measured every 3 months post surgery. Median follow-up was 29 months (minimum 3 months). The likelihood of reaching a uPSA of < or = 0.01 ng/ml at 3 months is 73% for the first 100 patients. This is statistically lower when compared with 83% (P < 0.05) for the second 100 patients and 80% for the third 100 patients (P < 0.05). Overall, 84% of patients with pT2 disease and 66% patients with pT3 disease had a uPSA of < or = 0.01 ng/ml at 3 months. Pre-operative PSA, PSA density and Gleason score were not correlated with outcome as determined by a uPSA of < or = 0.01 ng/ml at 3 months. Positive margins correlate with outcome as determined by a uPSA of < or = 0.01 ng/ml at 3 months but operative time and tumour volume do not (P < 0.05). Attempt at nerve sparing had no adverse effect on achieving a uPSA of < or = 0.01 ng/ml at 3 months. uPSA can be used as an early end-point in the analysis of oncological outcomes after radical prostatectomy. It is one of many measures that can be used in calculating a surgeon's learning curve for laparoscopic radical prostatectomy and in bench-marking performance. With experience, a surgeon can achieve in excess of an 80% chance of obtaining a uPSA nadir of < or = 0.01 ng/ml at 3 months after laparoscopic RRP for a British population. This is equivalent to most published open series.

What is the current management of women with ovarian endometriomas undergoing assisted reproductive treatment (ART) in the UK? It appears that the majority of gynaecologists in the UK offer surgery (mostly cystectomy) for endometriomas prior to ART, regardless of the presence of symptoms. The ideal management of endometriomas in women undergoing ART remains controversial and presents a dilemma to reproductive specialists. This was a national cross-sectional survey. A total of 388 gynaecologists completed the questionnaire. All clinicians fully registered with the Royal College of Obstetricians and Gynaecologists were contacted. An 11-item survey was administered electronically using Survey Monkey software. Quantitative data were analysed using descriptive and comparative statistics. The majority of responders were consultants (65%), 25% practiced ART and 65% performed laparoscopic surgery. Overall, 95% of responders would offer surgery for endometriomas in women undergoing ART, either on the basis of the size (>3-5 cm) of the endometrioma (52%), the presence of symptoms (16%), the presence of multiple/bilateral endometriomas (2%), regardless of the size and symptoms (19%) or only to women undergoing IVF (6%). The remaining 5% of responders would not offer surgery before ART. Excision was the most common surgical modality (68%), followed by ablation (25%). Laparoscopic surgeons were almost twice as likely to 'offer surgery to all patients with endometriomas prior to ART' compared with clinicians performing laparotomy (22 versus 12%, P < 0.001). Our overall response rate, with answers to the questionnaire, was low (15%). However, the response rate amongst reproductive specialists was estimated at 60%. It is possible that there might have been an element of bias towards over-representation of responders who are more concerned about 'normalization' of the pelvic anatomy. Furthermore, our survey relied on self-reporting of practice and it is possible that being presented with a list of 'ideal' options may have resulted in respondent bias. Despite the available evidence that surgery for endometriomas does not improve the outcome of ART and may damage ovarian reserve, it seems that the majority of gynaecologists in the UK offer ovarian cystectomy to their patients.

Atelectasis occurs regularly after induction of general anesthesia, persists postoperatively, and may contribute to significant postoperative morbidity and additional health care costs. Laparoscopic surgery has been reported to be associated with an increased incidence of postoperative atelectasis. It has been shown that during general anesthesia, obese patients have a greater risk of atelectasis than nonobese patients. Preventing atelectasis is important for all patients but is especially important when caring for obese patients. We randomly allocated 66 adult obese patients with a body mass index between 30 and 50 kg/m(2) scheduled to undergo laparoscopic bariatric surgery into 3 groups. According to the recruitment maneuver used, the zero end-expiratory pressure (ZEEP) group (n = 22) received the vital capacity maneuver (VCM) maintained for 7-8 s applied immediately after intubation plus ZEEP; the positive end-expiratory pressure (PEEP) 5 group (n = 22) received the VCM maintained for 7-8 s applied immediately after intubation plus 5 cm H(2)O of PEEP; and the PEEP 10 group (n = 22) received the VCM maintained for 7-8 s applied immediately after intubation plus 10 cm H(2)O of PEEP. All other variables (e.g., anesthetic and surgical techniques) were the same for all patients. Heart rate, noninvasive mean arterial blood pressure, arterial oxygen saturation, and alveolar-arterial Pao(2) gradient (A-a Pao(2)) were measured intraoperatively and postoperatively in the postanesthesia care unit (PACU). Length of stay in the PACU and the use of a nonrebreathing O(2) mask (100% Fio(2)) or reintubation were also recorded. A computed tomographic scan of the chest was performed preoperatively and postoperatively after discharge from the PACU to evaluate lung atelectasis. Patients in the PEEP 10 group had better oxygenation both intraoperatively and postoperatively in the PACU, lower atelectasis score on chest computed tomographic scan, and less postoperative pulmonary complications than the ZEEP and PEEP 5 groups. There was no evidence of barotrauma in any patient in the 3 study groups. Intraoperative alveolar recruitment with a VCM followed by PEEP 10 cm H(2)O is effective at preventing lung atelectasis and is associated with better oxygenation, shorter PACU stay, and fewer pulmonary complications in the postoperative period in obese patients undergoing laparoscopic bariatric surgery.

The study objective was to describe and evaluate our single center (University Hospital Liège) experience with totally laparoscopic bypass surgery compared with conventional open surgery to treat aortoiliac occlusive disease. A retrospective database review of all patients undergoing aortobifemoral bypass for aortoiliac occlusive disease in our center, between 2003 and 2009, was performed. During this period, a total of 251 consecutive patients were identified. Among these patients, 95 underwent totally laparoscopic aortobifemoral bypass (group I) and 156 conventional open surgery (group II). Demographic data, operative data, postoperative recovery data, complications, two-year follow-up, morbidity and mortality were analysed according to the laparoscopic and conventional open group. Patients included 160 men and 91 women. The mean age was 61 years (range, 40 to 88 years) in both groups. Indications for surgery were invalidating claudication in 87%, rest pain in 7%, trophic disorders in 5%, impotence in 1.6% and digestive claudication in 1.2%. Prior to bypass surgery, 11 (11.6%) for the group I and 41 (26.3%) for the group II had undergone one or more abdominal surgical procedures. A transperitoneal and retrocolic approach was preferred in all laparoscopic procedures. Laparoscopic aortobifemoral bypass (LABF) required an operative time of 242 minutes (range, 129 to 465) and open aortobifemoral bypass (OABF), 200 minutes (range, 105 to 430). The mean aortic cross clamping time was 62 minutes in group I and 33 minutes in group II. Mean blood loss was more important in group II (1010 ml) than in group I (682 ml). The average length of hospital stay was 8.1 days for LABF compared with an average of 12 days for OABF. In 21 cases (20%) conversion to open surgery was necessary in the laparoscopic group. Systemic morbidity was significantly higher in the OABF group. Thirty-day postoperative mortality was 2% for group II. There was no hospital mortality in the laparoscopic group. Twenty nine patients were lost to follow-up and the mean follow-up was 23.5 months. Analysis of the results shows that laparoscopic aortobifemoral bypass for aortoiliac occlusive disease is a safe procedure. The statistically significant advantages observed in the majority of our patients were decreased blood loss, faster post-operative recovery and shorter hospital stay. In the two groups, late morbidity attributable to the bypass prosthesis was minimal compared with other causes.

Acute remifentanil exposure during intraoperative analgesia might enhance sensitivity to noxious stimuli and nociceptive responses to innocuous irritation. Cyclooxygenase inhibition was demonstrated to attenuate experimental remifentanil-induced hyperalgesia (RIH) in rodents and human volunteers. The study aimed to compare the effects of preoperative and postoperative flurbiprofen axetil (FA) on RIH after surgery. Ninety patients undergoing elective laparoscopic gynecologic surgery were randomly assigned to receive either intravenous placebo before anesthesia induction (Group C); or intravenous FA (1.0 mg/kg) before anesthesia induction (Group F1) or before skin closure (Group F2). Anesthesia consisted off sevoflurane and remifentanil (0.30 μg/kg/min). Postoperative pain was managed by sufentanil titration in the postanesthetic care unit, followed by sufentanil infusion via patient-controlled analgesia. Mechanical pain threshold (primary outcome), pain scores, sufentanil consumption, and side-effects were documented for 24 hours postoperatively. Postoperative pain score in Group F1 was lower than Group C. Time of first postoperative sufentanil titration was prolonged in Group F1 than Group C (P=0.021). Cumulative sufentanil consumption in Group F1 was lower than Group C (P<0.001), with a mean difference of 8.75 (95% confidence interval, 5.21-12.29) μg. Mechanical pain threshold on the dominant inner forearm was more elevated in Group F1 than Group C (P=0.005), with a mean difference of 17.7 (95% confidence interval, 5.4-30.0) g. Normalized hyperalgesia area was decreased in Group F1 compared to Group C (P=0.007). No statistically significant difference was observed between Group F2 and Group C. Preoperative FA reduces postoperative RIH in patients undergoing laparoscopic gynecologic surgery under sevoflurane-remifentanil anesthesia.

Growing evidence suggests that the level of pneumoperitoneal pressure is directly correlated with postoperative pain in patients undergoing laparoscopic procedures. However, only limited evidence is available in the field of gynaecologic surgery. Therefore, this study aimed to compare the effects of low (8mmHg), standard (12mmHg) and high (15mmHg) pneumoperitoneal pressures (LPP

Should all distal pancreatectomies be performed laparoscopically?

Merchant, Nipun B; Parikh, Alexander A; Kooby, David A

Despite the relatively slow start of laparoscopic pancreatectomy relative to other laparoscopic resections, an increasing number of these procedures are being performed around the world. Operations that were once considered impossible to perform laparoscopically, such as pancreaticoduodenectomy and central pancreatectomy are gaining momentum. Technology continues to improve, as does surgical experience and prowess. There are both enough experience and data (though retrospective) to confirm that LDP with or without spleen preservation appears to be a safe treatment for benign or noninvasive lesions of the pancreas. Based on the fact that LDP can be performed with similar or shorter operative times, blood loss, complication rates, and length of hospital stay than ODP, it can be recommended as the treatment of choice for benign and noninvasive lesions in experienced hands when clinically indicated. It is very difficult to make clear recommendations with regard to laparoscopic resection of malignant pancreatic tumors due to the lack of conclusive data. As long as margins are negative and lymph node clearance is within accepted standards, LDP appears to have no untoward oncologic effects on outcome. Certainly more data, preferably in the manner of a randomized clinical trial, are needed before additional recommendations can be made. Potential benefits of laparoscopic resection for cancer include the ability to inspect the abdomen and abort the procedure with minimal damage if occult metastases are identified. This does not delay the onset of palliative chemotherapy, which would be the primary treatment in that circumstance. In fact, there is evidence to suggest that there is a greater likelihood of receiving systemic therapy if a laparotomy is avoided in patients who have radiologically occult metastases. Patients may also undergo palliative laparoscopic gastric and biliary bypass if indicated. Faster wound healing may also translate into a shorter waiting time before initiating adjuvant chemotherapy and/or radiation therapy. If the patient develops a wound infection, the infection should be more readily manageable with smaller incisions. Although not proven clinically relevant in humans, the reduction in perioperative stress associated with laparoscopic resection may translate to a cancer benefit for some patients. One report compared markers of systemic inflammatory response in 15 subjects undergoing left pancreatectomy. Eight had hand-access laparoscopic procedures and the rest had standard open surgery. The subjects in the laparoscopic group had statistically lower C-reactive protein levels than the open group on postoperative days one (5.5 mg/dL versus 9.7 mg/dL, P = .006) and three (8.5 mg/dL versus 17.7 mg/dL, P = .003), suggesting that the laparoscopic approach to left pancreatectomy is associated with less inflammation. While this report is underpowered, it supports the notion that MIS cancer surgery may induce less of a systemic insult to the body than standard open cancer surgery. More work in this area is necessary before any firm conclusions can be drawn. An important issue to consider is that of training surgeons to perform these complex procedures laparoscopically. Not all pancreatectomies are amenable to the laparoscopic approach, even in the most skilled hands. As such, only a percentage of cases will be performed this way and expectations to educate surgeons adequately to perform advanced laparoscopic procedures can be unrealistic, resulting in more "on-the-job" training. Another aspect that draws some controversy is that of the totally laparoscopic procedure versus the hand-access approach. No laparoscopic instrument provides the tactile feedback possible to obtain with the hand. The HALS approach allows for this, and the opportunity to control bleeding during the procedure. HALS also provides a way to improve confidence during the learning-curve phase of these operations. Finally, it is important to remember that if the procedure is failing to progress laparoscopically, or if cancer surgery principles are likely to be violated, the surgeon (and the patient) must be willing to abort the laparoscopic approach and complete the operation using standard open technique. During the next few years we can expect to see more robust outcome data with laparoscopic pancreatectomy. The expectation is that more data will come to light demonstrating benefits of laparoscopic pancreatic resection as compared with open technique for selected patients. Several groups are considering randomized trials to look at these endpoints. Although more retrospective and prospectively maintained data will certainly be presented, it is less likely that randomized data specifically examining the question oflaparoscopic versus open pancreatectomy for cancer will mature, due to some of the limitations discussed above. Additional areas of discovery are in staple line reinforcement for left pancreatectomy and suturing technology for pancreatico-intestinal anastomosis. Robotic surgery may have a role in pancreatic surgery. Improving optics and visualization with flexible endoscopes with provide novel surgical views potentially improving the safety of laparoscopy. Another area in laparoscopic surgery that is gaining momentum is that of Natural Orifice Transluminal Endoscopic Surgery (NOTES). NOTES represents the "holy grail" of incisionless surgery. Can we enucleate a small tumor off the pancreatic body by passing an endoscope through the gastric (or colonic) wall, and bring the specimen out via the mouth or anus? Can we use this approach for formal left pancreatectomies? Pioneers have already developed a porcine model of left pancreatectomy. This technology must clear several hurdles before it is cancer ready; however, technology is moving at a rapid pace.

The aim of the study was to compare value (outcomes/costs) of proctectomy in patients with rectal cancer by 3 approaches: open, laparoscopic, and robotic. The role of minimally invasive proctectomy in rectal cancer is controversial. In the era of value-based medicine, costs must be considered along with outcomes. Primary rectal cancer patients undergoing curative intent proctectomy at our institution between 2010 and 2014 were included. Patients were grouped by approach [open surgery, laparoscopic surgery, and robotic surgery (RS)] on an intent-to-treat basis. Groups were compared by direct costs of hospitalization for the primary resection, 30-day readmissions, and ileostomy closure and for short-term outcomes. A total of 488 patients were evaluated; 327 were men (67%), median age was 59 (27-93) years, and restorative procedures were performed in 333 (68.2%). Groups were similar in demographics, tumor characteristics, and treatment details. Significant outcome differences between groups were found in operative and anesthesia times (longer in the RS group), and in estimated blood loss, intraoperative transfusion, length of stay, and postoperative complications (all higher in the open surgery group). No significant differences were found in short-term oncologic outcomes. Direct cost of the hospitalization for primary resection and total direct cost (including readmission/ileostomy closure hospitalizations) were significantly greater in the RS group. The laparoscopic and open approaches to proctectomy in patients with rectal cancer provide similar value. If robotic proctectomy is to be widely applied in the future, the costs of the procedure must be reduced.

Abstract Background: Metabolic syndrome is associated with higher risk for cardiovascular disease, sleep apnea, and nonalcoholic steatohepatitis, all common conditions in patients referred for bariatric surgery, and it may predict early postoperative complications. The objective of this study was to determine the prevalence of metabolic syndrome, defined using updated National Cholesterol Education Program criteria, in adults undergoing bariatric surgery and compare the prevalence of baseline co-morbid conditions and select operative and 30-day postoperative outcomes by metabolic syndrome status. Methods: Complete metabolic syndrome data were available for 2275 of 2458 participants enrolled in the Longitudinal Assessment of Bariatric Surgery-2 (LABS-2), an observational cohort study designed to evaluate long-term safety and efficacy of bariatric surgery in obese adults. Results: The prevalence of metabolic syndrome was 79.9%. Compared to those without metabolic syndrome, those with metabolic syndrome were significantly more likely to be men, to have a higher prevalence of diabetes and prior cardiac events, to have enlarged livers and higher median levels of liver enzymes, a history of sleep apnea, and a longer length of stay after surgery following laparoscopic Roux-en-Y gastric bypass (RYGB) and gastric sleeves but not open RYGB or laparoscopic adjustable gastric banding. Metabolic syndrome status was not significantly related to duration of surgery or rates of composite end points of intraoperative events and 30-day major adverse surgical outcomes. Conclusions: Nearly four in five participants undergoing bariatric surgery presented with metabolic syndrome. Establishing a diagnosis of metabolic syndrome in bariatric surgery patients may identify a high-risk patient profile, but does not in itself confer a higher risk for short-term adverse postsurgery outcomes.

Current evidence suggests that local anesthetic wound infiltration should be employed as part of multimodal postoperative pain management. There is scarce data concerning the benefits of this anesthetic modality in laparoscopic weight loss surgery. Therefore, we analyzed the influence of trocar site infiltration with bupivacaine on the management of postoperative pain in laparoscopic bariatric surgery. This retrospective randomized study included 47 patients undergoing primary obesity surgery between January and September 2014. Laparoscopic gastric bypass was performed in 39 cases and sleeve gastrectomy in 8 cases. Patients were stratified into two groups depending on whether preincisional infiltration with bupivacaine and epinephrine was performed (study group, 27 patients) or not (control group, 20 patients). Visual analogue scale (VAS), International Pain Outcomes questionnaire, and rescue medication records were reviewed to assess postoperative pain. VAS scores in the study group and sleeve gastrectomy group were lower than those in the control and gastric bypass groups in the first 4 h postoperatively without reaching statistical significance (p > 0.05). VAS scores did not differ in any other period of time. No statistically significant differences in pain perception were registered according to the patient's pain outcomes questionnaire or the need for rescue medication. The present study did not conclusively prove the efficacy of bupivacaine infiltration by any of the three evaluation methods analyzed. Nevertheless, preincisional infiltration provides good level of comfort in the immediate postoperative period when analgesia is most urgent.

Laparoscopic surgery is normally performed under general anaesthesia, but regional techniques have been found beneficial, usually in the management of patients with major medical problems. Encouraged by such experience, we performed a feasibility study of segmental spinal anaesthesia in healthy patients. Twenty ASA I or II patients undergoing elective laparoscopic cholecystectomy received a segmental (T10 injection) spinal anaesthetic using 1 ml of bupivacaine 5 mg ml-1 mixed with 0.5 ml of sufentanil 5 microg ml-1. Other drugs were only given (systemically) to manage patient anxiety, pain, nausea, hypotension, or pruritus during or after surgery. The patients were reviewed 3 days postoperatively by telephone. The spinal anaesthetic was performed easily in all patients, although one complained of paraesthesiae which responded to slight needle withdrawal. The block was effective for surgery in all 20 patients, six experiencing some discomfort which was readily treated with small doses of fentanyl, but none requiring conversion to general anaesthesia. Two patients required midazolam for anxiety and two ephedrine for hypotension. Recovery was uneventful and without sequelae, only three patients (all for surgical reasons) not being discharged home on the day of operation. This preliminary study has shown that segmental spinal anaesthesia can be used successfully and effectively for laparoscopic surgery in healthy patients. However, the use of an anaesthetic technique involving needle insertion into the vertebral canal above the level of termination of the spinal cord requires great caution and should be restricted in application until much larger numbers of patients have been studied.

Infection or malfunction of ventriculo-peritoneal (VP) shunts is a severe complication during laparoscopic surgery involving the gastrointestinal or urinary tract. It has been recently suggested to externalize the shunt or convert into a ventriculo-atrial shunt to prevent this complication with laparoscopic approach. Herein, we present a novel technique for management of the VP shunt during robot-assisted laparoscopic (RAL) urologic procedures. After port placement and diagnostic peritoneoscopy, an Endopouch bag (Ethicon Endo-Surgery) was inserted into the peritoneal cavity and the distal end of the shunt was placed into the pouch. The Endopouch suture was synched around the shunt and the pouch was placed in the subhepatic space during the surgery. The intraperitoneal pressure was maintained at 12 mm Hg during the entire procedure. Metronidazole, gentamicin, and vancomycin were administered as prophylaxis. Following the completion of the surgery and profuse irrigation of the peritoneal cavity, the shunt was repositioned within the peritoneum. We evaluated perioperative shunt-related complications. We used this technique in four patients with VP shunt undergoing RAL cystoplasty and appendicovesicostomy and/or colonic enema channel formation. The average age of the patient at surgery was 10.8 (7-14) years. One patient was converted to open because of failure to progress due to multiple adhesions and the shunt was externalized temporarily. At a mean follow-up of 13 (3-20) months, no shunt-related complications were seen. In our preliminary experience, the use of an intracorporeal Endopouch bag with controlled pneumoperitoneal pressure to protect the VP shunt may be an effective alternative to prevent complications related to it during RAL urologic surgery involving the gastrointestinal or urinary tract. Further studies will be needed to confirm our results.

Single incision laparoscopic surgery (SILS) represents the latest advancement in minimally invasive surgery, combining the benefits of conventional laparoscopic surgery, such as less pain and faster recovery, with improved cosmesis. Although the successful use of this technique is well reported in general surgery and urology, there is a lack of studies on SILS in gynaecology. To evaluate the feasibility, safety, cosmesis and outcome of SILS in gynaecology. A prospective case series analysis of 105 women scheduled to undergo surgery by SILS from August 2010 to November 2011. Intra-operative data such as operative time, estimated blood loss, complications, additional ports and hospital stay were collected. Post-operative pain and cosmetic outcomes (scar size) were also recorded. Out of 105 women, SILS was performed for 84 (60 excisions of endometriosis, 13 divisions of adhesions, five hysterectomies, two mesh sacrohysteropexies and four ovarian cystectomies). SILS was not undertaken for 21 women because of a number of factors, including the lack of required equipment (eg bariatric scope, SILS port, roticulating instruments and diathermy leads). Four women required insertion of additional ports because of surgical difficulties. One intra-operative (uterine perforation) and seven post-operative complications (six wound infections and one vault haematoma) occurred. Mean operation times were as follows: mesh sacrohysteropexy - 60 min, excision of endometriosis - 55 min, hysterectomy - 150 min, laparoscopic division of adhesions - 62 min and ovarian cystectomy - 40 min. Our experience shows that SILS is a feasible and safe technique for the surgical management of various gynaecological conditions. Satisfaction is high because of improved cosmesis and reduced analgesic requirements post-operatively. © 2012 The Authors ANZJOG © 2012 The Royal Australian and New Zealand College of Obstetricians and Gynaecologists.

Over the years various therapeutic techniques for diverticulitis have been developed. Laparoscopic peritoneal lavage (LPL) appears to be a safe and useful treatment, and it could be an effective alternative to colonic resection in emergency surgery. This prospective observational study aims to assess the safety and benefits of laparoscopic peritoneal lavage in perforated sigmoid diverticulitis. We surgically treated 70 patients urgently for complicated sigmoid diverticulitis. Thirty-two (45.7%) patients underwent resection of the sigmoid colon and creation of a colostomy (Hartmann technique); 21 (30%) patients underwent peritoneal laparoscopic lavage; 4 (5.7%) patients underwent colostomy by the Mikulicz technique; and the remaining 13 (18.6%) patients underwent resection of the sigmoid colon and creation of a colorectal anastomosis with a protective ileostomy. The 66 patients examined were divided into 3 groups: 32 patients were treated with urgent surgery according to the Hartmann procedure; 13 patients were treated with resection and colorectal anastomosis; 21 patients were treated urgently with laparoscopic peritoneal lavage. We had no intraoperative complications. The overall mortality was 4.3% (3 patients). In the LPL group the morbidity rate was 33.3%. Currently it cannot be said that LPL is better in terms of mortality and morbidity than colonic resection. These data may, however, be proven wrong by greater attention in the selection of patients to undergo laparoscopic peritoneal lavage.

The observation of hemodynamic and metabolic impairment related to CO2 pneumoperitoneum and postoperative mesenteric ischemia reports following laparoscopic procedures have raised concern about local and systemic effects of increase intraabdominal pressure during laparoscopic procedures. The present study aims to evaluate the metabolic and acid base responses of using high pressure versus low pressure pneumoperitonium in patients undergoing laparoscopic cholecystectomy in a prospective randomized clinical trial. 20 ASA I-II patients scheduled for elective laparoscopic cholecystectomy were randomly allocated to one of two study groups; high pressure pneumoperitoneum 12-14mmHg (HPP, n=10) versus low pressure pneumoperitoneum 6-8mmHg (LPP, n=10) undergoing laparoscopic cholecystectomy. Arterial blood gases and lactate levels were determined after induction of anesthesia (before pneumoperitonium), then after 10 min, then 30 min after insufflations and at the end of surgery and 1 hour postoperatively. Nurses in recovery unit reported pain assessment starting postoperatively until 3 hours on a 10mm VAS (0-10). Statistical significant was established at P<0.05. Bicarbonate was significantly (P>0.0412) lower in high pressure group at 30 min and 60 min after insufflations. In high pressure group lactate levels increased significantly as compared to low pressure group, (at 30 minutes after the establishment of abdominal pneumatic inflation P<0.006 and remained significantly increased (P<0.001) until the end of surgery and one hour thereafter) (P<0.001). The mean postoperative pain score during second hour (VAS) at HPP group was 7.4 +/- 1.17 which is significantly (P < or = 0.006) higher than pain score in LPP group 5.0 +/- 1.886. Shoulder tip pain was reported in 3 patients in the high pressure group and only one patient in the lower pressure group. High-pressure pneumoperitonium causes statistically significant elevation in the arterial lactate level intraoperatively until one hour post operatively. It also causes higher pain score and shoulder tip pain.

Although laparoscopic hepatectomy has increasingly been used to treat cancers in the liver, the accuracy of intraoperative diagnosis may be inferior to that of open surgery because the ability to visualize and palpate the liver surface during laparoscopy is relatively limited. Fluorescence imaging has the potential to provide a simple compensatory diagnostic tool for identification of cancers in the liver during laparoscopic hepatectomy. In 17 patients who were to undergo laparoscopic hepatectomy, 0.5 mg/kg body weight of indocyanine green (ICG) was administered intravenously within the 2 weeks prior to surgery. Intraoperatively, a laparoscopic fluorescence imaging system obtained fluorescence images of its surfaces during mobilization of the liver. In all, 16 hepatocellular carcinomas (HCCs) and 16 liver metastases (LMs) were resected. Of these, laparoscopic ICG fluorescence imaging identified 12 HCCs (75%) and 11 LMs (69%) on the liver surfaces distributed over Couinaud's segments 1-8, including the 17 tumors that had not been identified by visual inspections of normal color images. The 23 tumors that were identified by fluorescence imaging were located closer to the liver surfaces than another nine tumors that were not identified by fluorescence imaging (median [range] depth 1 [0-5] vs. 11 [8-30] mm; p < 0.001). Like palpation during open hepatectomy, laparoscopic ICG fluorescence imaging enables real-time identification of subcapsular liver cancers, thus facilitating estimation of the required extent of hepatic mobilization and determination of the location of an appropriate hepatic transection line.

To explore the influencing factors of reproduction status in women undergoing laparoscopic myomectomy (LM). A total of 278 LM patients were recruited.We retrospectively reviewed the reproduction status of 87 pregnant cases after LM. The correlations of their pregnancy outcomes and such clinical profiles as age, operative techniques, biological characteristics of fibroids (number, type, size and location) were analyzed.No uterine rupture occurred during the gestation period. None of them switched to open surgery due to laparoscopic difficulties. However, one patient had a laparoscopic suture for secondary bleeding of uterine incision. At 3 months post-operation, sonography showed no heterogeneous echo, effusion and hematoma in uterine incision.Incision through uterine cavity occurred intraoperatively in 8 cases, but no intrauterine adhesion was found on hysteroscopy 3 months later. And 87 women became pregnant and the postoperative fertilization time was from 2 months to 5 years. Age influenced the postoperative pregnancy rate.Other factors such as location, number and size of fibroid had no impact on fertility. For achieving a high conception rate and guaranteeing the safety of pregnant women, a clinician should select reasonable surgical approaches, perform accurate anatomical restoration, apply strict hemostasis and choose a right time of conception.

Complications within laparoscopic surgery, similar to classic surgery are inevitable and require immediate actions both to diminish intraoperative risks and to choose the appropriate therapeutic attitude. Peritonitis and hemorrhagic incidents are both part of the complications aspect of laparoscopic surgery. Fortunately, the incidence is limited, thus excluding the rejection of celioscopic methods. Patient's risks and benefits are to be analyzed carefully prior recommending laparoscopic surgery. This study presents a statistical analysis of peritonitis consecutive to laparoscopic surgery, experience of "Sf. Ioan" Emergency Hospital, Bucharest, and Department of Surgery (2000-2010). There were 180 (0,96%) complicated situations requiring reinterventions, from a total of 18676 laparoscopic procedures. 106 cases (0,56%) represented different grades of postoperative peritonitis. Most frequently, there were consecutive laparoscopic appendicectomia and colecistectomia. During the last decade, few severe cases of peritonitis followed laparoscopic bariatric surgical procedures. This study reflects the possibility of unfavorable evolution of postoperative peritonitis comparing with hemorrhagic incidents within laparoscopic surgery.

It remains controversial whether open or laparoscopic surgery should be indicated for elderly patients with colorectal cancer and a poor performance status. In those patients aged 80 years or older with Eastern Cooperative Oncology Group performance status score of 2 or greater who received elective surgery for stage 0 to stage III colorectal adenocarcinoma and had no concomitant malignancies and who were enrolled in a multicenter case-control study entitled "Retrospective study of laparoscopic colorectal surgery for elderly patients" that was conducted in Japan between 2003 and 2007, background characteristics and short-term and long-term outcomes for open surgery and laparoscopic surgery were compared. Of the 398 patients included, 295 underwent open surgery and 103 underwent laparoscopic surgery. There were no significant differences in the baseline characteristics between open surgery and laparoscopic surgery patients, except for previous abdominal surgery and TNM stage. The median operation duration was shorter with open surgery (open surgery, 153 min; laparoscopic surgery, 202 min; P < 0.001), and less blood loss occurred with laparoscopic surgery (median open surgery, 109 g; median laparoscopic surgery, 30 g; P < 0.001). An operation duration of 180 min or more (odds ratio, 1.97; 95 % confidence interval, 1.17-3.37; P = 0.011) and selection of laparoscopic surgery (odds ratio, 0.41; 95 % confidence interval, 0.22-0.75; P = 0.003) were statistically significant in the multivariate analysis for postoperative morbidity. Moreover, laparoscopic surgery did not result in an inferior overall survival rate compared with open surgery (log-rank test P = 0.289, 0.278, 0.346, 0.199, for all-stage, stage 0-I, stage II, and stage III disease, respectively). Laparoscopic surgery in elderly colorectal cancer patients with a poor performance status is safe and not inferior to open surgery in terms of overall survival.

Structured Abstract Background Laparoscopic sleeve gastrectomy has recently surpassed gastric bypass and laparoscopic adjustable gastric banding as the most common weight-loss procedure. Previously, substantial concerns existed regarding variation in perioperative safety with bariatric surgery. This study aimed to assess rates of perioperative complications for laparoscopic sleeve gastrectomy across hospitals and in relation to procedure volume. Study Design We analyzed 8,693 patients who underwent laparoscopic sleeve gastrectomy from 2013 through 2014 across 40 hospitals in the Michigan Bariatric Surgery Collaborative. Mixed-effects logistic regression was used to assess hospital variation in risk- and reliability-adjusted rates of overall and serious 30-day complications and their relationship with hospital annual stapling procedure volume (gastric bypass and sleeve gastrectomy). Results Overall, 5.4% of patients experienced perioperative complications. Adjusted rates of overall complications varied three-fold across hospitals, ranging from 3.6% (95% CI, 1.9–6.8%) to 11.0% (95% CI, 7.7–15.5%). Serious complications occurred in just 1.2% of patients and varied minimally. In this analysis, hospital volume was not associated with overall or serious complications. The 1 hospital with significantly lower overall complication rates was high-volume (≥125 procedures/year); however, of the 4 hospitals with significantly higher complication rates, 3 were medium-volume (50–124 procedures/year) and 1 was high-volume. The remaining hospitals were not significantly different than the cohort mean. Conclusions Serious complications among patients undergoing laparoscopic sleeve gastrectomy were relatively infrequent. Rates of overall complications varied widely across Michigan hospitals enrolled in a quality collaborative, although this variation was unrelated to volume standards required for accreditation as a comprehensive bariatric surgery center.

Tumor recurrence after radical resection of hepatic tumors is not uncommon, suggesting that malignant lesions are missed during surgery. Intraoperative navigation using fluorescence guidance is an innovative technique enabling real-time identification of (sub)capsular liver tumors. The objective of the current study was to compare fluorescence imaging (FI) and conventional imaging modalities for laparoscopic detection of both primary and metastatic tumors in the liver. Patients undergoing laparoscopic resection of a malignant hepatic tumor were eligible for inclusion. Patients received standard of care, including preoperative CT and/or MRI. In addition, 10 mg indocyanine green was intravenously administered 1 day prior to surgery. After introduction of the laparoscope, inspection, FI, and laparoscopic ultrasonography (LUS) were performed. Histopathological examination of resected suspect tissue was considered the gold standard. Twenty-two patients suspected of having hepatocellular carcinoma (n = 4), cholangiocarcinoma (n = 2) or liver metastases from colorectal carcinoma (n = 12), uveal melanoma (n = 2), and breast cancer (n = 2) were included. Two patients were excluded because their surgery was unexpectedly postponed several days. Twenty-six malignancies were resected in the remaining 20 patients. Sensitivity for various modalities was 80 % (CT), 84 % (MRI), 62 % (inspection), 86 % (LUS), and 92 % (FI), respectively. Three metastases (12 %) were identified solely by FI. All 26 malignancies could be detected by combining LUS and FI (100 % sensitivity). This study demonstrates added value of FI during laparoscopic resections of several hepatic tumors. Although larger series will be needed to confirm long-term patient outcome, the technology already aids the surgeon by providing real-time fluorescence guidance.

In an elective laparoscopic surgery, the cosmetic outcome becomes increasingly important. We conducted a study to evaluate the cosmetic outcome 3 months after a laparoscopic procedure and compared skin adhesive (SA) versus transcutaneous suture (TS). A randomized, controlled, prospective study was conducted at a single study centre in Hamburg, Germany. Seventy-seven patients undergoing laparoscopic surgery with two lower abdominal port sites met the study requirements. It was decided randomly which port site would be closed with SA. The opposite site was closed with TS. Wounds were assessed after 7-12 days and after 3 months. Cosmetic outcome was measured by a visual analogue scale (VAS) completed by the patient, by the Hollander wound evaluation scale (HWES) and by the judgement of blinded investigators. Seventy-seven subjects were randomized. Complete data from the 3-month follow-up visit were available from 56 patients (72.7 %). The VAS scale ranged from 0 to 100 mm with "0" representing the best possible cosmetic outcome. Median satisfaction was 2 mm in the TS group and 3 mm in the SA group. The mean was high in both groups 4.6 (s = 13.1) versus 3.8 mm (s = 4.6). The outcome was neither clinically nor statistically significant. Cosmetic outcome was assessed by an investigator, and the HWES showed no difference. In regard to complications, no difference was found between SA and TS, either. In conclusion this study demonstrated that closure of laparoscopic port-site wounds leads to equivalent outcomes whether SAs or TSs are used. Complications are rare in both methods. Thus, SAs seem to be a valid alternative to sutures in laparoscopic surgery. Registration site: www.clinicaltrials.gov . NCT02179723.

This study was focused to understand how endometriosis altered the uterine and cervical bacterial community. Urogenital swabs and uterine washes were collected from 19 pre-menopausal women undergoing laparoscopic surgery for pelvic pain, suspected endometriosis (experimental n = 10), and women undergoing laparoscopic surgery for benign ovarian/uterine conditions (control n = 9). Patients were followed for the next year and repeat cervical swabs were obtained. Bacterial community composition was assessed from these samples using Illumina next generation 16Smore » rRNA amplicon sequencing. Bacterial communities were significantly different between sample sites, the uterus and cervix, and stage III endometriosis resulted in significant alterations in the cervical bacterial community. Both bacterial richness and phylogenetic diversity increased in association with stage III endometriosis. Surgical intervention resulted in a stabilized cervical bacterial community for a short period of time.

Emerging evidence suggests that a laparoscopic approach to colorectal procedures generates fewer adhesions. Even though laparoscopic ileal pouch-anal anastomosis (IPAA) is a lengthy procedure, the prospect of fewer adhesions may justify this approach. The aim of this study was to assess abdominal and adnexal adhesion formation following laparoscopic versus open IPAA in patients with ulcerative colitis. A diagnostic laparoscopy was performed at time of ileostomy closure. All abdominal quadrants and the pelvis were video recorded systematically and graded offline. The incisional adhesion score (IAS; range 0-6) and total abdominal adhesion score (TAS; range 0-10) were calculated, based on the grade and extent of adhesions. Adnexal adhesions were classified by the American Fertility Society (AFS) adhesion score. A total of 43 patients consented to participate, of whom 40 could be included in the study (laparoscopic 28, open 12). Median age was 38 (range 20-61) years. There was no difference in age, sex, body mass index, American Society of Anesthesiologists grade and time to ileostomy closure between groups. The IAS was significantly lower after laparoscopic IPAA than following an open procedure: median (range) 0 (0-5) versus 4 (2-6) respectively (P = 0·004). The TAS was also significantly lower in the laparoscopic group: 2 (0-6) versus 8 (2-10) (P = 0·002). Applying the AFS score, women undergoing laparoscopic IPAA had a significantly lower mean(s.d.) prognostic classification score than those in the open group: 5·2(3·7) versus 20·0(5·6) (P = 0·023). Laparoscopic IPAA was associated with significantly fewer incisional, abdominal and adnexal adhesions in comparison with open IPAA. Copyright © 2011 British Journal of Surgery Society Ltd.

Lymphatic complications are a common occurrence after staging surgery for early-stage ovarian cancer (eEOC). We investigated whether the introduction of minimally invasive surgery influences the risk of developing lymphoceles and lymphorrhea in patients undergoing staging for eEOC. For this purpose, data of consecutive patients affected by eEOC undergoing staging surgery between January 1980 and January 2016 were retrospectively reviewed, and a systematic review and meta-analysis was performed. This systematic review was registered in the International Prospective Register of Systematic Review. Among 341 patients included in the present study, 47 severe postoperative complications occurred (13.7%), including 40 lymphatic complications: 31 symptomatic lymphoceles (9%) and 9 cases of lymphorrhea (2.6%), respectively. Laparoscopic staging correlated with a lower risk of developing any severe lymphatic complications in comparison with open surgery (p = .02). In particular, the laparoscopic approach and para-aortic node involvement were associated with a trend toward lower lymphoceles (odds ratio, .13; 95% confidence interval, .07-2.20; p = .05) and a trend toward higher risk of lymphorrhea developing (odds ratio, 4.02; 95% confidence interval, .93-17.3; p = .06), respectively. In conclusion, the implementation of a minimally invasive approach might result in a slight reduction of lymphatic complications after eEOC staging. Copyright © 2017 AAGL. Published by Elsevier Inc.

Yu, Jiang-Hong; Wu, Ji-Xiang; Yu, Lei; Li, Jian-Ye

2016-12-01

Giant hiatal hernia (GHH) comprises 5% of hiatal hernia and is associated with significant complications. The traditional operative procedure, no matter transthoracic or transabdomen repair of giant hiatal hernia, is characteristic of more invasion and more complications. Although laparoscopic repair as a minimally invasive surgery is accepted, a part of patients can not tolerate pneumoperitoneum because of combination with cardiopulmonary diseases or severe posterior mediastinal and neck emphesema during operation. The aim of this article was to analyze our experience in gasless laparoscopic repair with abdominal wall lifting to treat the giant hiatal hernia. We performed a retrospective review of patients undergoing gasless laparoscopic repair of GHH with abdominal wall lifting from 2012 to 2015 at our institution. The GHH was defined as greater than one-third of the stomach in the chest. Gasless laparoscopic repair of GHH with abdominal wall lifting was attempted in 27 patients. Mean age was 67 years. The results showed that there were no conversions to open surgery and no intraoperative deaths. The mean duration of operation was 100 min (range: 90-130 min). One-side pleura was injured in 4 cases (14.8%). The mean postoperative length of stay was 4 days (range: 3-7 days). Median follow- up was 26 months (range: 6-38 months). Transient dysphagia for solid food occurred in three patients (11.1%), and this symptom disappeared within three months. There was one patient with recurrent hiatal hernia who was reoperated on. Two patients still complained of heartburn three months after surgery. Neither reoperation nor endoscopic treatment due to signs of postoperative esophageal stenosis was required in any patient. Totally, satisfactory outcome was reported in 88.9% patients. It was concluded that the gasless laparoscopic approach with abdominal wall lifting to the repair of GHH is feasible, safe, and effective for the patients who cannot tolerate the pneumoperitoneum.

This study presents a technical report of a standardized approach to the perinephric area in a series of pediatric patients, demonstrating that whatever renal or suprarenal surgery is planned, this can be approached and accomplished laparoscopically with an identical or very similar port triangulation, thus facilitating the learning curve within the same surgical team. All patients undergoing renal and adrenal gland surgery with a minimally invasive approach in the period from October 2008 to November 2013 were retrospectively reviewed and included in the study. Technical details and clinical outcomes are described. In total, 68 patients matched the inclusion criteria and were therefore retrospectively examined. No major intraoperative complication occurred. Two patients developed recurrent pelvic-ureteric junction obstruction and were managed with double J stent positioning and laparoscopic dismembered pyeloplasty, respectively. Two patients presenting with adrenal mass experienced a moderate bleeding that could be treated conservatively. Thanks to the reproducibility of the procedure and on the grounds of the presented experience, we support the proposal that the transperitoneal laparoscopic approach to the kidney and the adrenal gland could represent a relatively easy and safe way to quickly achieve confidence and skill in the management of related diseases.

We conducted a population-based cohort study in men who underwent RARP (n = 4 947), LRP (n = 5 479) or ORP (n = 6 873) between 2008 and 2012 in the English National Health Service (NHS) using national cancer registry records linked to Hospital Episodes Statistics, an administrative database of admissions to NHS hospitals. We identified the occurrence of any severe urinary or severe stricture-related complication within 2 years of surgery using a validated tool. Multi-level regression modelling was used to determine the association between the type of surgery and occurrence of complications, with adjustment for patient and surgical factors. Men undergoing RARP were least likely to experience any urinary complication (10.5%) or a stricture-related complication (3.3%) compared with those who had LRP (15.8% any or 5.7% stricture-related) or ORP (19.1% any or 6.9% stricture-related). The impact of the type of surgery on the occurrence of any urinary or stricture-related complications remained statistically significant after adjustment for patient and surgical factors (P < 0.01). Men who underwent RARP had the lowest risk of developing severe urinary complications within 2 years of surgery. © 2017 The Authors BJU International published by John Wiley & Sons Ltd on behalf of BJU International.

To assess the hormonal, metabolic and physiological effects of laparascopic surgery performed under a sedative analgesic combination of detomidine and buprenorphine in standing horses. Prospective study. Eight healthy adult Dutch Warmblood horses and five healthy adult ponies undergoing laparoscopy were studied. Five healthy adult horses not undergoing laparoscopy were used as a control group. The sedative effect of an initial detomidine and buprenorphine injection was maintained using a continuous infusion of detomidine alone. The heart and respiratory rate, arterial blood pH and arterial oxygen and carbon dioxide tensions were monitored, while blood samples were taken for the measurement of glucose, lactate, cortisol, insulin and nonesterified fatty acids (NEFA). The same variables were monitored in a control group of horses which were sedated, but which did not undergo surgery. At the end of the sedation period the effects of detomidine were antagonized using atipamezole. The protocol provided suitable conditions for standing laparoscopy in horses. Laparoscopy induced obvious metabolic and endocrine responses which, with the exception of NEFA values, were not significantly different from changes found in the control group. While atipamezole did not produce detectable adverse effects, it is possible that anatagonism may not be essential. The technique described reliably produces adequate sedation and analgesia for laparoscopic procedures. The level of sedation/analgesia was controlled by decreasing or increasing the infusion rate. Antagonism of the effects of detomidine may not be necessary in all cases.

There is an increasing trend to use laparoscopy for rectal cancer surgery. Although laparoscopic and open rectal resections appear oncologically equivalent, there is little information on the cost of different surgical approaches. With the current health care crisis and the importance of optimizing health care resources and patient outcomes, the cost of care is an important factor. The aim of this study was to evaluate the cost-effectiveness of laparoscopy in rectal cancer. This was a case-matched study. This study was conducted at a tertiary referral center. Patients undergoing elective rectal cancer resection between 2007 and 2012 were selected. A review of a prospective database for elective laparoscopic rectal cancer resections was performed. Laparoscopic cases were matched to open cases based on age, BMI, operative procedure, and diagnostic-related group. The primary outcomes measured were the cost of care, hospital length of stay, discharge disposition, readmission, postoperative complications, and mortality rates. Two hundred fifty-four matched cases were included in the analysis: 125 laparoscopic (49%) and 129 open (51%). The cTNM stage (p = 0.39), tumor distance from the anal verge (p = 0.07), and rate of neoadjuvant therapy received between the laparoscopic and open groups were similar (p = 0.12). Operating time (p< 0.01) and cost per operating room minute (p = 0.04) were significantly higher in the open group. The groups were oncologically equivalent, based on circumferential resection margin (p = 0.15). The laparoscopic group had a significantly shorter length of stay (p < 0.01) and lower total hospital cost (p < 0.01). Postoperative complications, 30-day readmission, reoperation, and mortality rates were similar. However, significantly more patients undergoing open resection required intensive care unit care (p = 0.03), skilled nursing (p = 0.03), or home care services (p < 0.01) at discharge. This investigation was conducted at a single institution and it is a retrospective study with potential bias. Laparoscopy is cost-effective for rectal cancer surgery, improving both health care expenditures and patient outcomes. For selected patients, laparoscopic rectal cancer resection can reduce length of stay, operating time, and resource utilization.

The scope of general surgery practice has evolved tremendously in the last 20 years. However, clinical experience in general surgery residency training has undergone relatively little change. To evaluate the current scope of academic general surgery and its implications on surgical residency. The University HealthSystem Consortium and Association of American Medical Colleges established the Faculty Practice Solution Center (FPSC) to characterize physician productivity. The FPSC is a benchmarking tool for academic medical centers created from revenue data collected from more than 90,000 physicians who practice at 95 institutions across the United States. The FPSC database was queried to evaluate the annual mean procedure frequency per surgeon (PFS) in each calendar year from 2006 through 2011. The associated work relative value units (wRVUs) were also examined to measure physician effort and skill. During the 6-year period, 146 distinct Current Procedural Terminology codes were among the top 100 procedures, and 16 of these procedures ranked in the top 10 procedures in at least 1 year. The top 10 procedures accounted for more than half (range, 52.5%-57.2%) of the total 100 PFS evaluated for each year. Laparoscopic Roux-en-Y gastric bypass was consistently among the top 10 procedures in each year (PFS, 18.2-24.6). The other most frequently performed procedures included laparoscopic cholecystectomy (PFS, 30.3-43.5), upper gastrointestinal tract endoscopy (PFS, 26.5-34.3), mastectomy (PFS, 16.5-35.0), inguinal hernia repair (PFS, 15.5-22.1), and abdominal wall hernia repair (PFS, 21.6-26.1). In all years, laparoscopic Roux-en-Y gastric bypass generated the highest number of wRVUs (wRVUs, 491.0-618.2), and laparoscopic cholecystectomy was regularly the next highest (wRVUs, 335.8-498.7). A significant proportion of academic general surgery is composed of bariatric surgery, yet surgical training does not sufficiently emphasize the necessary exposure to technical expertise and clinical management of the patient undergoing bariatric surgery. As the scope of general surgery practice continues to evolve, general surgery residency training will need to better integrate the exposure to bariatric surgery.

Crohn's disease is established in laparoscopic surgery due to partial bowel dissection and low postoperative complication rate. However, laparoscopic surgery for ulcerative colitis remains further discussed even if the trend of minimally invasive technique exists. This study is to figure out how laparoscopic surgery works for ulcerative colitis. Sixteen controlled trials were identified through the search strategy mentioned below. There was only one prospective randomized study among the studies selected. A meta-analysis pooled the outcome effects of laparoscopic surgery and open surgery was performed. Fixed effect model or random effect model was respectively used depending on the heterogeneity test of trials. Postoperative fasting time and postoperative hospital stay were shorter in laparoscopic surgery for ulcerative colitis (-1.37 [-2.15, -0.58], -3.22 [-4.20, -2.24], respectively, P < 0.05). Overall complication rate was higher in open surgery, compared with laparoscopic surgery (54.8% versus 39.3%, P = 0.004). However, duration of laparoscopic surgery for ulcerative colitis was extended compared with open surgery (weighted mean difference 69.29 min, P = 0.04). As to recovery of bowel function, peritoneal abscess, anastomotic leakage, postoperative bowel obstruction, wound infection, blood loss, and mortality, laparoscopic surgery did not show any superiority over open surgery. Re-operation rate was almost even (5.2% versus 7.3%). The whole conversion to open surgery was 4.2%. Laparoscopic surgery for ulcerative colitis was at least as safe as open surgery, even better in postoperative fasting time, postoperative hospital stay, and overall complication rate. However, clinical value of laparoscopic surgery for ulcerative colitis needed further evaluation with more well-designed and long-term follow-up studies.

The biomechanical and mental strains placed on the surgeon while performing laparoscopic procedures are significantly higher compared with open surgical techniques. We undertook this study to assess the prevalence of surgeons' deleterious perceptions or injuries related to laparoscopic urologic surgery. Members of endourological society were mailed a questionnaire evaluating their laparoscopic experience, total number of standard laparoscopic surgeries (SLS), hand-assisted laparoscopic surgeries (HALS), and robotic-assisted laparoscopic surgeries (RALS) they performed. The subjects reported any neuromuscular or arthritic injuries sustained during laparoscopic surgery, and graded the degree of pain, numbness, and fatigue they experienced. A total of 73 urologists completed the questionnaires. The average responder was 44 years old, had completed a median of 117 procedures, and was performing 3 laparoscopic surgeries per week. Neuromuscular or arthritic symptoms during surgery were reported by 22 responders (30%), the most common was finger paresthesia (18%). At the conclusion of HALS, 45% of the surgeons suffered from hand and wrist numbness and 37% reported pain in these areas. A significant association was observed between the risk of sustaining injury during surgery and the total number of laparoscopic procedures performed by the responder (P = 0.016). RALS was the procedure least associated with injuries, and HALS the most. The laparoscopic operating theater is a hostile ergonomic environment. Surgeons' awareness of the common injuries associated with laparoscopic surgery and careful equipment adjustments before surgery are mandatory to minimize injury. Future improvements in instrument design according to ergonomic principles are highly warranted.

To assess the use of laparoscopic surgeries (LS) and the association between its performance and hospitals' preference for LS over open surgeries. LS is increasingly used in many abdominal surgeries, albeit both with and without solid guideline recommendations. To date, the hospitals' preference (LS vs. open surgeries) and its association with in-hospital outcomes has not been evaluated. We enrolled patients undergoing 8 types of gastrointestinal surgeries in 2011-2013 in the Japanese National Clinical Database. We assessed the use of LS and the occurrences of surgery-related morbidity and mortality during the study period. Further, for 4 typical LS procedures, we assessed the hospitals' preference for LS by modeling the propensity to perform LS (over open surgeries) from patient-level factors, and estimating each institution's observed/expected (O/E) ratio for LS use. Institutions with O/E>2 were defined as LS-dominant. Using hierarchical logistic regression models, we assessed the association between LS preference and in-hospital outcomes. Among 1,377,118 patients undergoing gastrointestinal procedures in 2,336 participating hospitals, use of LS increased in all 8 procedures (35.1% to 44.7% for distal gastrectomy (DG), and 27.5% to 43.2% for right hemi colectomy (RHC)). Those operated at LS-dominant hospitals were at an increased risk of operative death (OR 1.83 [95%CI, 1.37-2.45] for DG, 1.79 [95%CI, 1.43-2.25] for RHC) compared to standard O/E level hospitals (0.5≤O/E<2.0). LS use widely increased during 2011-2013 in Japan. Facilities with higher than expected LS use had higher mortality compared to other hospitals, suggesting a need for careful patient selection and dissemination of the procedure.

The aim of this study was to compare the effectiveness and long-term anatomic and functional results of laparoscopic peritoneal vaginoplasty and laparoscopic sigmoid vaginoplasty. From January 2002 to December 2010, 40 patients with congenital vaginal agenesis were prospectively randomized to undergo either laparoscopic peritoneal vaginoplasty (26 cases) or laparoscopic sigmoid vaginoplasty (14 cases) in 2:1 ratio. Pre- and postoperative examination findings, Female Sexual Function Index (FSFI) questionnaire responses, and sexual satisfaction rates are reported. All surgical procedures were performed successfully, with no intraoperative complications. The laparoscopic peritoneal vaginoplasty group had significantly less blood loss and a surgery shorter on average than the laparoscopic sigmoid colovaginoplasty group. Postoperative course was uneventful for all patients in both groups, though postoperative retention time and hospital stay were less for peritoneal vaginoplasty patients than for sigmoid vaginoplasty patients. Mean neovaginal length, excessive mucous production, sexual life initiation time, and sexual satisfaction rate were similar between groups. Patient complaints of abdominal discomfort, unusual odor from vaginal secretions, and vaginal contraction during intercourse were higher in the sigmoid colovaginoplasty group (p < 0.005 vs. peritoneal vaginoplasty). Postoperative FSFI scores did not differ significantly between groups. Relative to laparoscopic sigmoid colovaginoplasty, laparoscopic peritoneal vaginoplasty provides good anatomic and functional results and excellent patient satisfaction.

The natural course of sigmoid colon diverticulitis during conservative therapy and the assessment of the perioperative morbidity after sigmoid colon resection are differently evaluated by surgeons and gastroenterologists. The "fast-track" rehabilitation accelerates the reconvalescence and reduces the rate of postoperative general complications after colorectal surgery. The results of the laparoscopic "Fast-track" sigmoidectomy should be examined within a quality assurance program to better evaluate the perioperative risks following surgical management of diverticulitis. A prospective data collection within the voluntary quality assurance program "fast-track" Kolon II was performed. All participating clinics agreed on a multimodal, evidence-based standard perioperative treatment in terms of a "fast-track" rehabilitation for elective operations for sigmoid diverticulitis. Data from 846 patients undergoing laparoscopic "fast-track" sigmoid colon resection in 23 surgical departments in Germany were collected and evaluated. The mean age of the patients was 63 years (range 23 - 91). 203 patients (24 %) had severe co-morbidities (ASA classification III - IV). A conversion to conventional open surgery was necessary in 51 cases (6 %). Complications occurred in 93 patients (11 %). 76 patients suffered a surgical complication (8.9 %) and 32 patients (3.8 %) a general complication. Two patients died postoperatively due to multi-organ failure following anastomotic leaks. The patients took solid food in median on day 1 after surgery (range, 0 - 5) and passed stool on day 2 (range, 0 - 22). Predefined discharge criteria (free of pain on oral medication, normal oral feeding, stool) were met on day 4 (range, 1 - 58) and the patients were discharged on day 7 (range, 3 - 72). The 30-day re-admission rate was 3.9 %. Patients undergoing laparoscopic "fast-track" sigmoidectomy had a low rate of general complications and had a rapid reconvalescence with a short postoperative in-patient treatment as documented in a german quality assurance program.

Diclectin(R) (DCL) is an effective antiemetic used for relief of nausea and vomiting in pregnancy. It is unknown whether DCL is effective in the prevention of postoperative nausea and vomiting (PONV). We conducted a randomized, stratified, double-blind placebo-controlled trial to examine the incidence of PONV in women undergoing elective laparoscopic tubal ligation in the day surgery setting. DCL (doxylamine succinate 10 mg and pyridoxine hydrochloride 10 mg) was administered orally the night before surgery, the morning of surgery, and upon hospital discharge. We enrolled 146 women in the trial, 127 of whom were included in the effectiveness analysis and 102 of whom were included in the efficacy analysis. We did not detect a difference in the incidence of nausea and vomiting in the first six hours postoperatively after adjusting for additional antiemetics administered. Patients receiving DCL as compared with placebo were significantly less likely to experience vomiting six to 24 hr postoperatively [5/59 (8.5%) vs 14/55 (25.4%), P < 0.017]. Treated patients tended to return to work earlier than those who received placebo (1.74 vs 3.7 days P = NS). Perioperative oral DCL reduces the incidence of postoperative vomiting in women undergoing elective laparoscopic tubal ligation, and may accelerate return to work.

We investigated the efficacy of electroacupuncture in reducing the duration of postoperative ileus and hospital stay after laparoscopic surgery for colorectal cancer. We performed a prospective study of 165 patients undergoing elective laparoscopic surgery for colonic and upper rectal cancer, enrolled from October 2008 to October 2010. Patients were assigned randomly to groups that received electroacupuncture (n = 55) or sham acupuncture (n = 55), once daily from postoperative days 1-4, or no acupuncture (n = 55). The acupoints Zusanli, Sanyinjiao, Hegu, and Zhigou were used. The primary outcome was time to defecation. Secondary outcomes included postoperative analgesic requirement, time to ambulation, and length of hospital stay. Patients who received electroacupuncture had a shorter time to defecation than patients who received no acupuncture (85.9 ± 36.1 vs 122.1 ± 53.5 h; P < .001) and length of hospital stay (6.5 ± 2.2 vs 8.5 ± 4.8 days; P = .007). Patients who received electroacupuncture also had a shorter time to defecation than patients who received sham acupuncture (85.9 ± 36.1 vs 107.5 ± 46.2 h; P = .007). Electroacupuncture was more effective than no or sham acupuncture in reducing postoperative analgesic requirement and time to ambulation. In multiple linear regression analysis, an absence of complications and electroacupuncture were associated with a shorter duration of postoperative ileus and hospital stay after the surgery. In a clinical trial, electroacupuncture reduced the duration of postoperative ileus, time to ambulation, and postoperative analgesic requirement, compared with no or sham acupuncture, after laparoscopic surgery for colorectal cancer.

2014-02-01

Gastro-esophageal reflux disease is a troublesome disease for many patients, severely affecting their quality of life. Choice of treatment depends on a combination of patient characteristics and preferences, esophageal motility and damage of reflux, symptom severity and symptom correlation to acid reflux and physician preferences. Success of treatment depends on tailoring treatment modalities to the individual patient and adequate selection of treatment choice. PubMed, Embase, The Cochrane Database of Systematic Reviews, and the Cumulative Index to Nursing and Allied Health Literature (CINAHL) were searched for systematic reviews with an abstract, publication date within the last five years, in humans only, on key terms (laparosc* OR laparoscopy*) AND (fundoplication OR reflux* OR GORD OR GERD OR nissen OR toupet) NOT (achal* OR pediat*). Last search was performed on July 23nd and in total 54 articles were evaluated as relevant from this search. The laparoscopic Toupet fundoplication is the therapy of choice for normal-weight GERD patients qualifying for laparoscopic surgery. No better pharmaceutical, endoluminal or surgical alternatives are present to date. No firm conclusion can be stated on its cost-effectiveness. Results have to be awaited comparing the laparoscopic 180-degree anterior fundoplication with the Toupet fundoplication to be a possible better surgical alternative. Division of the short gastric vessels is not to be recommended, nor is the use of a bougie or a mesh in the vast majority of GERD patients undergoing surgery. The use of a robot is not recommended. Anti-reflux surgery is to be considered expert surgery, but there is no clear consensus what is to be called an 'expert surgeon'. As for setting, ambulatory settings seem promising although high-level evidence is lacking. Copyright © 2013 Elsevier Ltd. All rights reserved.

Single-port laparoscopic and robotic partial nephrectomy.

Partial nephrectomy (PN) for small renal masses provides effective oncologic outcomes. Single-port laparoscopic (SPL) and robotic surgeries are evolving approaches to advance minimally invasive surgery. To determine the feasibility of laparoscopic and robotic single-port PN. Since 2007, evaluation of patients undergoing SPL and single-port robotic (SPR) PN at a primary referral center was performed. Patients with small, solitary, exophytic-enhancing renal masses were selected. Patients with a solitary kidney, endophytic or hilar tumors, and previous abdominal and/or kidney surgery were excluded. Perioperative and pathologic data were entered prospectively into an institutional review board (IRB)-approved database. Tumor location determined either an open Hasson transperitoneal or retroperitoneal approach. A single multichannel port or Triport provided intra-abdominal access. The Harmonic Scalpel was used for tumor excision under normal renal perfusion. The da Vinci surgical robot was used for SPR cases. Patient demographics, perioperative, hematologic, and pathologic data as well as pain assessment using the Visual Analog Pain Scale (VAPS) were assessed. A total of seven patients underwent single-port PN (SPL=5, SPR=2). One patient with a right anterior upper-pole mass required conversion from SPL to standard laparoscopy following tumor excision because of intraoperative bleeding. Pathology revealed six lesions compatible with renal cell carcinoma (RCC) and one benign cyst. One negative frozen section came back focally positive on final histopathology. All other surgical margins were negative. A mean difference of 3.0+/-2.0 g/dl in hemoglobin was noted in all patients. Minimal pain was noted at discharge following both laparoscopic and robotic single-port surgery (VAPS=1.7+/-1.2 vs 1+/-0.5/10). SPL and SPR PN is feasible for select exophytic tumors. Robotics may improve surgical capabilities during single-port surgery.

Enhanced recovery after laparoscopic colorectal resection with primary anastomosis: accelerated discharge is safe and does not give rise to increased readmission rates.

Enhanced recovery programmes after colorectal surgery are promoted to minimize complications and expedite recovery, thus reducing length of hospital stay where appropriate and improving the overall standard of patient care. There are few published trials of enhanced recovery programmes in the context of laparoscopic colorectal surgery. Data were prospectively collected on all laparoscopic colorectal resections carried out in our institution from May 2004 to November 2009. An informal move to 48-h discharge was introduced in May 2004 and the official enhanced recovery programme was launched in November 2008. We identified all patients with a primary anastomosis discharged within 3 days of surgery. Early outcomes - leaks, complications, readmission rates and returns to theatre - were analysed. In all, 606 resections were performed in this period. Median length of stay was 4 (0-52) days. Of these patients, 279 (46%) met the criteria of accelerated discharge by day 3: 2 (0.7%) were discharged on the day of surgery, 70 (25.1%) within 24 h, 116 (41.6%) within 48 h and 91 (32.6%) by 72h. Age was not a significant factor in determining length of stay. Patients undergoing right hemicolectomy were more likely to be discharged by 24 h than those with left-sided anastomoses, and patients having total mesorectal excision resections were more likely to stay 3 days. The readmission rate was 4%, regardless of day of discharge. Accelerated discharge is feasible and safe. High readmission rates reported in enhanced recovery programmes after open colorectal surgery have not occurred in our laparoscopic experience. © 2012 The Authors.

2004-03-01

Laparoscopic surgery has become the treatment of choice for the management of perforated peptic ulcer. The advantages of laparoscopic repair for perforated peptic ulcer include less pain, a short hospital stay, and an early return to normal activity. Although the operation time of laparoscopic surgery is significantly longer than that of open surgery, laparoscopic technique is safe, feasible, and with morbidity and mortality comparable to that of the conventional open technique. To benefit from the advantages offered by minimally invasive laparoscopic technique, further study will need to determine whether laparoscopic surgery is safe in patients with generalized peritonitis or sepsis.

While laparoscopic cholecystectomy is generally considered less painful than open surgery, pain is one of the important reasons for delayed discharge after day-surgery and overnight stay following laparoscopic cholecystectomy. The safety and effectiveness of different pharmacological interventions such as non-steroidal anti-inflammatory drugs, opioids, and anticonvulsant analgesics in people undergoing laparoscopic cholecystectomy is unknown. To assess the benefits and harms of different analgesics in people undergoing laparoscopic cholecystectomy. We searched the Cochrane Central Register of Controlled Trials (CENTRAL), MEDLINE, EMBASE, Science Citation Index Expanded, and the World Health Organization International Clinical Trials Registry Platform portal (WHO ICTRP) to March 2013 to identify randomised clinical trials of relevance to this review. We considered only randomised clinical trials (irrespective of language, blinding, or publication status) comparing different pharmacological interventions with no intervention or inactive controls for outcomes related to benefit in this review. We considered comparative non-randomised studies with regards to treatment-related harms. We also considered trials that compared one class of drug with another class of drug for this review. Two review authors collected the data independently. We analysed the data with both fixed-effect and random-effects models using Review Manager 5 analysis. For each outcome, we calculated the risk ratio (RR) or mean difference (MD) with 95% confidence intervals (CI). We included 25 trials with 2505 participants randomised to the different pharmacological agents and inactive controls. All the trials were at unclear risk of bias. Most trials included only low anaesthetic risk people undergoing elective laparoscopic cholecystectomy. Participants were allowed to take additional analgesics as required in 24 of the trials. The pharmacological interventions in all the included trials were aimed at preventing pain after laparoscopic cholecystectomy. There were considerable differences in the pharmacological agents used and the methods of administration. The estimated effects of the intervention on the proportion of participants who were discharged as day-surgery, the length of hospital stay, or the time taken to return to work were imprecise in all the comparisons in which these outcomes were reported (very low quality evidence). There was no mortality in any of the groups in the two trials that reported mortality (183 participants, very low quality evidence). Differences in serious morbidity outcomes between the groups were imprecise across all the comparisons (very low quality evidence). None of the trials reported patient quality of life or time taken to return to normal activity. The pain at 4 to 8 hours was generally reduced by about 1 to 2 cm on the visual analogue scale of 1 to 10 cm in the comparisons involving the different pharmacological agents and inactive controls (low or very low quality evidence). The pain at 9 to 24 hours was generally reduced by about 0.5 cm (a modest reduction) on the visual analogue scale of 1 to 10 cm in the comparisons involving the different pharmacological agents and inactive controls (low or very low quality evidence). There is evidence of very low quality that different pharmacological agents including non-steroidal anti-inflammatory drugs, opioid analgesics, and anticonvulsant analgesics reduce pain scores in people at low anaesthetic risk undergoing elective laparoscopic cholecystectomy. However, the decision to use these drugs has to weigh the clinically small reduction in pain against uncertain evidence of serious adverse events associated with many of these agents. Further randomised clinical trials of low risk of systematic and random errors are necessary. Such trials should include important clinical outcomes such as quality of life and time to return to work in their assessment.

Fast-track Rehabilitation Accelerates Recovery After Laparoscopic Colorectal Surgery

2014-01-01

Background: Fast-track (FT) rehabilitation protocols have been shown to be successful in reducing both hospital stay and postoperative complications, as well as enhancing overall postoperative patient recovery. We are reporting the outcomes of our first group of patients undergoing colorectal surgery following the FT protocol. Patients and Methods: We performed a prospective study of patients, between January 1, 2007 and January 31, 2010, who underwent laparoscopic colorectal resections in accordance with the guidelines of FT rehabilitation protocol. Recovery parameters including time to removal of naso-gastric tube and urinary catheter, time to bowel function and to resume diet, and length of hospital stay were evaluated. Postoperative outcomes, that is, postoperative complications and mortality, reoperations, and readmissions were also studied. Results: A total of 71 patients, 30 women and 41 men, underwent FT rehabilitation for laparoscopic colorectal surgery. The mean age of the patients was 60 ± 16 years. The most common surgical procedures were right hemicolectomy 30% and anterior resection 27%. Liquid and regular diet were initiated on postoperative day 1.2 ± 0.4 and 2.1 ± 0.4, respectively. Overall postoperative morbidity was 8.5%. The mean length of stay was 4.4 ± 1.7 days, with only 3 readmissions. Forty-five patients fulfilled the FT care plan and were discharged on postoperative day 3. No reoperations or mortality were observed. Conclusions: FT rehabilitation results in favorable postoperative outcomes. Our data provides evidence and suggests that FT protocols should be implemented as a reliable method of preparation and recovery for laparoscopic colorectal surgery. PMID:25489207

Writing emotionally about upsetting life events (expressive writing) has been shown to speed healing of punch-biopsy wounds compared to writing objectively about daily activities. We aimed to investigate whether a presurgical expressive writing intervention could improve surgical wound healing. Seventy-six patients undergoing elective laparoscopic bariatric surgery were randomized either to write emotionally about traumatic life events (expressive writing) or to write objectively about how they spent their time (daily activities writing) for 20 min a day for 3 consecutive days beginning 2 weeks prior to surgery. A wound drain was inserted into a laparoscopic port site and wound fluid analyzed for proinflammatory cytokines collected over 24 hr postoperatively. Expanded polytetrafluoroethylene tubes were inserted into separate laparoscopic port sites during surgery and removed after 14 days. Tubes were analyzed for hydroxyproline deposition (the primary outcome), a major component of collagen and marker of healing. Fifty-four patients completed the study. Patients who wrote about daily activities had significantly more hydroxyproline than did expressive writing patients, t(34) = -2.43, p = .020, 95% confidence interval [-4.61, -0.41], and higher tumor necrosis factor-alpha, t(29) = -2.42, p = .022, 95% confidence interval [-0.42, -0.04]. Perceived stress significantly reduced in both groups after surgery. Expressive writing prior to bariatric surgery was not effective at increasing hydroxyproline at the wound site 14 days after surgery. However, writing about daily activities did predict such an increase. Future research needs to replicate these findings and investigate generalizability to other surgical groups.

Not many studies have explored the correlation between arterial carbon dioxide tension (PaCO 2 ) and end-tidal carbon dioxide tension (ETCO 2 ) in surgeries requiring pneumoperitoneum of more than 1 hour duration with the patient in non-supine position. The aim of our study was to evaluate the correlation of ETCO 2 with PaCO 2 in patients undergoing laparoscopic nephrectomy under general anaesthesia. A descriptive study was performed in thirty patients undergoing laparoscopic nephrectomy from September 2014 to August 2015. The haemodynamic parameters, minute ventilation, PaCO 2 and ETCO 2 measured at three predetermined points during the procedure were analysed. Correlation was checked using Pearson's Correlation Coefficient Test. P <0.05 was considered statistically significant. Statistical analysis of the values showed a positive correlation between ETCO 2 and PaCO 2 ( P < 0.05). Following carbon dioxide insufflation, both ETCO 2 and PaCO 2 increased by 5.4 and 6.63 mmHg, respectively, at the end of the 1 st hour. The PaCO 2 -ETCO 2 gradient was found to increase during the 1 st hour following insufflation (4.07 ± 2.05 mmHg); it returned to the pre-insufflation values in another hour (2.93 ± 1.43 mmHg). Continuous ETCO 2 monitoring is a reliable indicator of the trend in arterial CO 2 fluctuations in the American Society of Anesthesiologists Grades 1 and 2 patients undergoing laparoscopic nephrectomy under general anaesthesia.

The purpose of this study was to present strategies for performing computer-enhanced telesurgery in the morbidly obese patient. This was a prospective, institutional review board-approved, descriptive feasibility study (Canadian Task Force classification II-2) conducted at a university-affiliated hospital. Twelve class III morbidly obese women with a body mass index of 40 kg/m(2) or greater were selected to undergo robotic-assisted total laparoscopic hysterectomy. Robotic-assisted total laparoscopic hysterectomy, classified as type IVE, with complete detachment of the cardinal-uterosacral ligament complex, unilateral or bilateral, with entry into the vagina was performed. The median estimated blood loss was 146.3 mL (range, 15-550 mL), the mean length of stay in the hospital was 25.3 hours (range, 23- 48 hours), and the complication rate was 0%. The rate of conversion to laparotomy was 8%. The median surgical time was 109.6 minutes (range, 99 -145 minutes). Robotic-assisted total laparoscopic hysterectomy can be a safe and effective method of performing hysterectomies in select morbidly obese patients, allowing them the opportunity to undergo minimally invasive surgery without increased perioperative complications.

Sickle cell disease is a public health problem in Africa. The aim of this prospective study was to evaluate per and post-operative complications of laparoscopic cholecystectomy in sickle cell children in Senegal. from January 1999 to December 2006, an anesthetic protocol was applied to 39 sickle cell children undergoing a cholecystectomy. Among them, 20 experienced laparoscopic cholecystectomy. All these 20 patients had previously suffered from sickle cell visceral complications and were classified as ASA II (11 cases) and as ASA III (9 cases). Blood transfusion program aimed at sustaining haemoglobin level between 10 and 12 g/dl was implemented. The preoperative monitoring and anesthesia management were the same for these patients. During perioperative period, the prevention of pain, hypovolemia, hypothermia and acidosis was achieved. The mean insufflation duration of laparoscopy was 23 min (17-60 min), the mean surgery duration was 55 min (40-110 min), and the mean anesthesia duration was 78 min (88-135 min). Postoperative complications occurred in 9 patients: acute chest syndrome (n=2), postoperative hemolysis (n=5), vaso-occlusive crisis (n=2). Laparoscopic cholecystectomy can be carried out in sickle cell children affected with gallstones, provided that general anaesthetic rules were respected. An appropriate pre-, per- and postoperative anaesthesia is mandatory to reduce postoperative complications in children with sickle cell disease. Searching for early diagnosis of gallstones before occurrence of visceral complications should allow further optimal laparoscopic surgery.

Morbid obesity and bariatric surgery are both risk factors for the development of postoperative rhabdomyolysis (RML). RML results from injury to skeletal muscle, and a serum creatine phosphokinase (CK) level >1,000 IU/L is considered diagnostic of RML. The aim of this study was to determine if intraoperative intravenous fluid (IVF) volume affects postoperative CK levels following laparoscopic bariatric operations. Prospective, single blinded, and randomized trial was conducted. Patients scheduled to undergo laparoscopic sleeve gastrectomy, adjustable gastric band, or Roux-en-Y gastric bypass operations were randomized into two groups. Subjects in Group A received 15 ml/kg total body weight (TBW) of IV crystalloid solution during surgery, while subjects in Group B received 40 ml/kg TBW. Preoperative and postoperative CK and creatinine levels and intra- and postoperative urine output were monitored and recorded. Forty-seven patients were assigned to Group A and 53 patients to Group B. Group B patients had significantly higher urine output in the operating room, in the post-anesthesia care unit (PACU), and on postoperative days 0 and 1. Group B patients also had significantly lower serum creatinine level in the PACU and a trend towards lower creatinine levels on postoperative days 0, 1, and 2. There were no statistical differences in CK levels at any time between the two groups. Four patients in Group A and three patients in Group B developed postoperative RML. Conservative (15 ml/kg) versus liberal (40 ml/kg) intraoperative IVF administration did not change the incidence of RML in patients undergoing laparoscopic bariatric operations. Since the occurrence of RML in this patient population is relatively high, postoperative CK levels should be routinely obtained in patients at special risk.

Robotic surgery is gaining acceptance for distal pancreatectomy (DP). Nevertheless, no multi-institutional data exist to demonstrate the ideal clinical circumstances for use and the efficacy of the robot compared to the open or laparoscopic techniques, in terms of perioperative outcomes. The 2014 ACS-NSQIP procedure-targeted pancreatectomy data for patients undergoing DP were analyzed. Demographics and clinicopathological and perioperative variables were compared between the three approaches. Univariate and multivariable analyses were used to evaluate outcomes. One thousand eight hundred fifteen DPs comprised 921 open distal pancreatectomies (ODPs), 694 laparoscopic distal pancreatectomies (LDPs), and 200 robotic distal pancreatectomies (RDPs). The three groups were comparable with respect to demographics, ASA score, relevant comorbidities, and malignant histology subtype. Compared to the ODP group, patients undergoing RDP had lower T-stages of disease (P = 0.0192), longer operations (P = 0.0030), shorter hospital stays (P < 0.0001), and lower postoperative 30-day morbidity (P = 0.0476). Compared to the LDP group, RDPs were longer operations (P < 0.0001) but required fewer concomitant vascular resections (P = 0.0487) and conversions to open surgery (P = 0.0068). On multivariable analysis, neoadjuvant therapy (P = 0.0236), malignant histology (P = 0.0124), pancreatic reconstruction (P = 0.0006), and vascular resection (P = 0.0008) were the strongest predictors of performing an ODP. The open, laparoscopic, and robotic approaches to distal pancreatectomy offer particular advantages for well-selected patients and specific clinicopathological contexts; therefore, clearly demonstrating the most suitable use and superiority of one technique over another remains challenging.

Laparoscopic surgery for colorectal disease has become widespread as a minimally invasive treatment. This is important because the increasing availability of new devices allows us to perform procedures with a reduced length of surgery and decreased blood loss. We herein report the results of a literature review of energy sources for laparoscopic colorectal surgery, focused especially on 6 studies comparing ultrasonic coagulating shears (UCS) and other instruments. We also describe our laparoscopic dissection techniques using UCS for colorectal cancer. The short-term outcomes of surgeries using UCS and Ligasure for laparoscopic colorectal surgery were superior to conventional electrosurgery. Some authors have reported that the length of surgery or blood loss when Ligasure was used for laparoscopic colorectal surgery is less than when UCS was used. On the other hand, a recent study demonstrated that there were no significant differences between the short-term outcomes of UCS and Ligasure for laparoscopic colorectal surgery. It is therefore suggested that the choice of technique used should be made according to the surgeon’s preference. We also describe our laparoscopic dissection techniques using UCS (Harmonic ACE) for colorectal cancer with regard to the retroperitoneum dissection, dissection technique, dissection technique around the feeding artery, and various other dissection techniques. We therefore review the outcomes of using various energy sources for laparoscopic colorectal surgery and describe our laparoscopic dissection techniques with UCS (Harmonic ACE) for colorectal cancer.

Recently, the evaluation of postoperative results has focused on the opinion of the patient as of great relevance. Our objective was to evaluate the quality of recovery by questionnaire (QoR-15) in patients undergoing laparoscopic cholecystectomy, comparing desflurane versus a total intravenous technique with propofol (TIVA). A non-inferiority hypothesis was proposed between both techniques. Prospective longitudinal cohort study in patients undergoing laparoscopic cholecystectomy in which multimodal management was applied including low pneumoperitoneum pressures, deep neuromuscular block and pain prevention strategy and PONV. Anaesthesia maintenance was performed with either desflurane or propofol at the discretion of the anaesthesiologist. QoR-15 was evaluated pre-and 24hours after surgery. Sixty-one patients were evaluated: 29 in the desflurane group and 32 in the TIVA group with no differences in demographic parameters, ASA grade, and preoperative QoR-15 questionnaire. The duration of the intervention was superior in TIVA group, 55 ± 15 vs. 45 ± 9min in desflurane group; p =.05. The desflurane group received more fentanyl than the TIVA group: 200 ± 65 vs. 113 ± 38μg; p =.05. No differences in pain, PONV or time of stay between groups. QoR-15 at 24h decreased 7% relative to baseline, with no differences between groups. The quality of recovery evaluated by the patient was as favourable in the patients of the desflurane group as in those of the TIVA group in patients undergoing laparoscopic cholecystectomy as outpatients.

This study undertook the in vivo measurement of surface pressures applied by the fingers of the surgeon during typical representative retraction movements of key human abdominal organs during both open and hand-assisted laparoscopic surgery. Surface pressures were measured using a flexible thin-film pressure sensor for 35 typical liver retractions to access the gall bladder, 36 bowel retractions, 9 kidney retractions, 8 stomach retractions, and 5 spleen retractions across 12 patients undergoing open and laparoscopic abdominal surgery. The maximum and root mean square surface pressures were calculated for each organ retraction. The maximum surface pressures applied to these key abdominal organs are in the range 1 to 41 kPa, and the average maximum surface pressure for all organs and procedures was 14 ± 3 kPa. Surface pressure relaxation during the retraction hold period was observed. Generally, the surface pressures are higher, and the rate of surface pressure relaxation is lower, in the more confined hand-assisted laparoscopic procedures than in open surgery. Combined video footage and pressure sensor data for retraction of the liver in open surgery enabled correlation of organ retraction distance with surface pressure application. The data provide a platform to design strategies for the prevention of retraction injuries. They also form a basis for the design of next-generation organ retraction and space creation surgical devices with embedded sensors that can further quantify intraoperative retraction forces to reduce injury or trauma to organs and surrounding tissues.

To evaluate the effectiveness of ultrasound-guided transversus abdominis plane (TAP) and rectus sheath (RS) blocks in pain management and recovery after gynecological single-incision laparoscopic surgery (SILS). Abilateral TAP block (Group A, n = 9), bilateral TAP and RS blocks (Group B, n = 10), and a bilateral RS block (Group C, n = 9) with 40 ml ropivacaine per patient were conducted in 28 patients undergoing SILS for ovarian tumors. A pain score and walking distance in a 6-minute walk test (6MWT) were examined. Pain scores were significantly lower on postoperative day (POD) 3 than on POD 1 in Groups B (p = 0.03) and C (p = 0.02). The walking distance on POD 3 was comparable with that before surgery in Group C (p = 0.75), but shorter in Groups A (p = 0.004) and B (p = 0.02). The RS block alone was the most effective in relieving pain and accelerating general recovery after gynecological SILS.

The study set out to analyse the outcomes of an evolving accelerated recovery programme after laparoscopic colorectal resection (LCR). The results of a prospective electronic database (March 2000 - April 2008) were analysed. There were 353 consecutive patients undergoing 'three port' high anterior resection (AR) (237 without covering stoma) and 166 a right hemicolectomy (RHC). One hundred thirty-eight had postoperative analgesia using paracetamol IV and oral analgesia (IVP); 27 (16.3%) received additional parenteral morphine and were excluded. Patient controlled morphine analgesia (PCA) was used in 138. Transversus abdominis plane (TAP) blocks, supplemented by IV paracetamol and oral analgesia were used in the last 50 patients. The time to the resumption of diet was significantly reduced with TAP analgesia (median 12 h) and IVP (median 12 h) compared with PCA median (36 h) (chi(2) = 143; 4df: P < 0.001). The postoperative hospital stay was significantly reduced with TAP analgesia (median 2 days) and IVP (median 3 days) compared with PCA (median 5 days); chi(2) = 73; 2df: P < 0.001. Seventeen (34%) TAP and nine (6.5%) IVP patients were discharged within 24 h of surgery compared with no patient in the PCA group. Ninety-three per cent of PCA, 35% IVP and 10% TAP patients were discharged in more than 3 days. The movement towards 'accelerated recovery' was not associated with any increased risk of urinary retention, return to theatre, readmission and/or 30 day mortality. Laparoscopic surgery utilizing IV paracetamol and TAP blocks for postoperative analgesia aids safe effective 'accelerated recovery' in an unselected patient population undergoing right hemicolectomy and high anterior resection. Routine epidural anaesthesia is unnecessary for LCR. Morphine PCA is associated with delayed recovery.

Paralytic ileus after laparoscopic-assisted surgery often occurs. We investigated whether daikenchuto (DKT), a traditional Japanese herbal medicine, improves intestinal motility in patients undergoing laparoscopic-assisted colectomy for colon cancer. Fifty-four patients who underwent colectomy at Iwate Medical University Hospital between October 2010 and March 2012 were randomized to either the DKT group (7.5 g/day, p.o.) or the control group (lactobacillus preparation, 3g/day, p.o.). Primary endpoints included time to first flatus, bowel movement, and tolerance of diet after extubation. Secondary endpoints were WBC count, C-reactive protein (CRP) level, length of hospital stay, and postoperative ileus. Colonic transit time was measured using radiopaque markers and abdominal radiographs. Fifty-one patients (DKT, 26 vs. control, 25) were included in the per-protocol analysis. The DKT group had significantly faster time until first flatus (67.5 +/- 13.6h vs. 77.9 +/- 11.8h, P < 0.01) and bowel movement (82.9 +/- 17.8h vs. 99.5 +/- 18.9h, P < 0.01) and colonic transit time (91.9 +/- 19.8h vs. 115.2 +/- 12.8 h, P < 0.05). There were no significant intergroup differences in secondary endpoints and adverse events. DKT accelerates colonic motility in patients undergoing laparoscopic-assisted colectomy for colon cancer.

The aim of the present study was to prospectively investigate whether the anthropometric measures of A Body Shape Index (ABSI, taking into account waist circumference adjusted for height and weight) affects feasibility and outcome of laparoscopic liver resections. One hundred patients undergoing laparoscopic liver resection were prospectively included in the study (2014-2015). Preoperative clinical parameters, including body mass index (BMI) and ABSI were evaluated for associations with intraoperative outcome and postoperative results (morbidity, mortality and functional recovery). Twenty-two and 78 patients underwent major and minor hepatectomies, respectively. Conversion rate was 9%, mean blood loss was 210 ± 115 ml. Postoperative morbidity was 15% and mortality was nil. Mean length of stay was 4 days. When considering the entire series, ABSI was not associated with intra and postoperative outcome. After stratification of patients according to difficulty score, Pearson's correlation demonstrated an association between ABSI and intraoperative blood loss (P = 0.03) and time for functional recovery (P = 0.05) in patients undergoing resections with high score of difficulty. Body habitus has an influence on outcome of laparoscopic liver resections with high degree of difficulty, while feasibility and outcome of low difficulty resections seem not to be affected by anthropometric measures. © 2016 Japanese Society of Hepato-Biliary-Pancreatic Surgery.

Aerophagia is a rare but well-known comorbidity in patients with gastrooesophageal reflux disease. Particularly after laparoscopic Nissen fundoplication, it has proven to result in worse symptomatic outcome and a lower postoperative quality of life in comparison to patients without preoperative gas-related symptoms. Aim of the study was to compare the postoperative outcome in gastrooesophageal reflux disease patients with aerophagia as comorbidity after either laparoscopic 360 degrees 'floppy' Nissen fundoplication or 270 degrees Toupet fundoplication with main focus on the frequency and subjective impairment of gas-related symptoms. In 56 gastrooesophageal reflux disease patients, the comorbidity of aerophagia was diagnosed prior to laparoscopic antireflux surgery. Irrespective of their preoperative manometric findings, the patients were either scheduled to a laparoscopic 360 degrees 'floppy' Nissen (n=28) or a laparoscopic 270 degrees Toupet fundoplication (n=28). All patients have been analysed concerning the presence of gas-related symptoms preoperatively as well as 3 months after surgery. Additionally, the subjective degree of impairment was evaluated using a numerous rating scale (0=no perception/impairment, 100=most severe perception/impairment). The following symptoms have been analysed: ability/inability to belch, 'gas bloat', flatulence, postprandial fullness and epigastric pain. Before surgery, there were no significant differences between both surgical groups. Three months after surgery, significant differences (p<0.05-0.01) were found: patients who underwent a laparoscopic 270 degrees Toupet fundoplication suffered from less impairing gas bloat, flatulence and postprandial fullness when compared with patients with a 360 degrees 'floppy' Nissen fundoplication. The majority of these patients were able to belch postoperatively but felt no impairment due to this symptom. In contrast, patients of the Nissen group felt a significant impairment due to the inability to belch. Gas-related symptoms are very common in gastrooesophageal reflux disease patients with aerophagia as a comorbidity. Patients who undergo a laparoscopic Toupet fundoplication show less impairment in relation to gas-related problems compared with patients treated with a Nissen fundoplication for a follow-up period of at least 3 months. In the Toupet group, the ability to belch postoperatively seems to be a positive aspect from the patients' view which also improves the percentage of gas-related problems. However, long-term results are necessary.

In literature, only a few studies have prospectively compared the results of laparoscopic with open inguinal hernia repair yet none have compared bilateral inguinal hernia repair. The aim of this study is to compare the open Lichtenstein repair (OLR) with laparoscopic trans-abdominal preperitoneal (TAPP) repair in patients undergoing surgery for bilateral inguinal hernia. Patients were prospectively randomized between March 2013 and March 2015. Outcome parameters included hospital stay, operation time, postoperative complications, immediate postoperative pain and chronic pain, recurrence and quality of life. Sixty-one patients underwent TAPP repair and 73 underwent OLR. TAPP procedure had less early post-operative pain up to 7 days from surgery (p = 0.003), a shorter length of hospital stay (p = 0.001), less postoperative complications (p = 0.012) and less chronic pain (0.04) when compared with the OLR approach. TAPP procedure for bilateral inguinal hernia effectively reduces early postoperative pain, hospital stay and postoperative complications. Copyright © 2017 Elsevier Inc. All rights reserved.

The incidence of uterine rupture through a previous cesarean scar (CS) is declining as a result of a lower parity and fewer options for vaginal birth after cesarean. However, uterine ruptures attributable to other causes that traumatize the myometrium are on the rise. To determine whether changes in the causes of uterine rupture had occurred in recent years, we retrospective retrieved the clinical records of all singletons with uterine rupture observed in the delivery room of a Taiwanese tertiary obstetric center over a 15-year period. The overall uterine rupture rate was 3.8 per 10,000 deliveries. A total of 22 cases in 20 women (with two of them experiencing two episodes). Seven uterine ruptures occurred through a previous cesarean scar (CS ruptures, 32%), 13 through a non-cesarean scar (non-CS ruptures, 59%), whereas the remaining two (9%) were in women who did not previously undergo any surgery. All of the 13 non-CS ruptures were identified in women with a history of laparoscopic procedures to the uterus. Specifically, 10 (76%) occurred after a previous laparoscopic myomectomy, one (8%) following a hysteroscopic myomectomy, and two (16%) after a laparoscopic wedge resection of cornual ectopic pregnancy. Severe bleeding (blood loss >1500 mL) requiring transfusions was more frequent in women who experienced non-CS compared with CS ruptures (10 versus 1 case, respectively, P = 0.024). Patients with a history of endoscopic uterine surgery should be aware of uterine rupture during pregnancy.

Although the many advantages of laparoscopic surgery have made it an established technique, training in laparoscopic surgery posed problems not encountered in conventional surgical training. Virtual reality simulators open up new perspectives for training in laparoscopic surgery. Under realistic conditions in real time, trainees can tailor their sessions with the VR simulator to suit their needs and goals, and can repeat exercises as often as they wish. VR simulators reduce the number of experimental animals needed for training purposes and are suited to the pursuit of research in laparoscopic surgery.

Despite accelerated recovery programs and the widespread uptake of laparoscopic surgery, postoperative ileus remains a significant factor affecting length of stay after abdominal surgery. Alvimopan, an opioid-receptor antagonist, may reduce the incidence of postoperative ileus and expedite hospital discharge. The aim of this study was to perform a meta-analysis to determine the role of alvimopan in accelerating GI recovery and hospital discharge after laparoscopic and open abdominal surgery performed within an accelerated recovery program. Cochrane (1999-2010), Embase (1980-2010), MEDLINE (1980-2010), and International Pharmaceutical Abstracts (1970-2010) were searched for relevant double-blinded, randomized controlled trials. Twelve milligrams of alvimopan and placebo were given to patients enrolled in an accelerated recovery program after abdominal surgery. The primary outcomes measured were the length of stay as defined by the writing of the hospital discharge order and GI-3 and GI-2 GI tract recovery. : Three trials were included that reported on a pooled modified intention-to-treat population of 1388 patients; 685 (49%) patients received alvimopan. On meta-analysis, alvimopan reduced time to the hospital discharge order (HR 1.37 (1.21, 1.62), p < 0.0001), GI-3 recovery (HR 1.42 (1.25, 1.62), p < 0.001), and GI-2 recovery (HR 1.49 (1.32, 1.68), p < 0.0001). The search criteria identified only a small number of trials of alvimopan after abdominal surgery with no randomized trials of alvimopan after laparoscopic surgery. In addition, the use of length of hospital stay as the primary outcome measure may be inappropriate, because it is open to many confounding factors. Finally, adverse events, in particular, adverse cardiovascular events, were not considered. Alvimopan 12 mg can further reduce time to GI recovery and hospital discharge in patients undergoing abdominal surgery within an accelerated recovery program. Investigation into the effect of alvimopan following laparoscopic surgery and additional cost-benefit analyses are required to further define the role of this intervention.

To measure procedure-related hospital readmissions within 30 days after discharge for patients who have a hysterectomy for benign disease. Secondary outcome quality measures evaluated were cost, estimated blood loss, length of stay and sum of costs associated with readmissions. Retrospective cohort study (Canadian Task Force classification II-2). Academic community hospital. Patients who underwent hysterectomy to treat benign disease from January 2008 to December 2012. Patients were grouped according to route of hysterectomy: robotic-assisted laparoscopic hysterectomy (robotic), laparoscopic hysterectomy (laparoscopic), abdominal hysterectomy (open via laparotomy), and vaginal hysterectomy (vaginal). Inclusion criteria were met by 2554 patients: 601 in the robotic group, 427 in the laparoscopic group, 1194 in the abdominal group, and 332 in the vaginal group. Readmission rates in the robotic cohort were significantly less (p<.05) than in non-robotic cohorts: Robotic (1%), laparoscopic (2.5%), open (3.5%), vaginal (2.4%). Estimated blood loss, length of stay, and sum of readmission costs were also significantly less in the robotic cohort (p<.05) compared with the other 3 cohorts. Patients who undergo robotic-assisted laparoscopic hysterectomy have a significantly lower chance of readmission <30 days after surgery compared with those who undergo laparoscopic, abdominal (open) hysterectomy, and vaginal approaches. Patients in the robotics cohort also experienced a shorter length of stay, less estimated blood loss, and a cost savings associated with readmissions when compared to non-robotic approaches. Prospective registries describing quality outcomes, total sum of costs including 30 days follow-up, as well as patient-related quality of life benefits are recommended to confirm these findings and determine which surgical route offers the highest patient and societal value.

Laparoscopy has been a standard procedure in most medical centres providing surgical services for many years. Both the range and number of laparoscopic procedures performed are constantly increasing. Over the last decade, laparoscopic procedures have been successfully applied both in emergency and oncological surgery. However, treatment costs have become a more important factor in choosing between open or laparoscopic procedures. To present the total real costs of open and laparoscopic cholecystectomy, appendectomy and sigmoidectomy. Between 1 May 2010 and 30 March 2015 in the Department of Thoracic Surgery, General and Oncological Surgery, Medical University of Lodz, and in the Department of General Surgery of the Saint John of God Hospital, Lodz, doctors performed 1404 cholecystectomies, 392 appendectomies and 88 sigmoidectomies. A total of 97% of the cholecystectomy procedures were laparoscopic and 3% were open. Similarly, 22% of total appendectomies were laparoscopic and 78% were open, while 9% of sigmoidectomies were laparoscopic and 91% open. The requirement for single-use equipment in laparoscopic procedures increases the expense. However, after adding up all other costs, surprisingly, differences between the costs of laparoscopic and open procedures ranged from 451 PLN/€ 114 for laparoscopic operations to 611 PLN/€ 153 for open operations. Laparoscopic cholecystectomy, considered the standard surgery for treating gallbladder diseases, is cheaper than open cholecystectomy. Laparoscopic appendectomy and sigmoidectomy are safe methods of minimally invasive surgery, slightly more expensive than open operations. Of all the analyzed procedures, one-day laparoscopic cholecystectomy is the most profitable. The costs of both laparoscopic and open sigmoidectomy are greatly underestimated in Poland.

Background Extremely obese adolescents are increasingly undergoing bariatric procedures, which restrict dietary intake. However, there are as yet no data available which describe the change in caloric density or composition of the adolescent bariatric patient’s diet pre- and post-operatively. Objective Assess the 1-year change in dietary composition of adolescents undergoing bariatric surgery. Setting Tertiary care children’s hospital Methods Twenty-seven subjects [67% female, 77% white, age 16.7 ± 1.4 years, baseline body mass index (BMI) 60.1 ± 14.1 kg/m2] were prospectively enrolled into an observational cohort study one month prior to laparoscopic Roux-en-Y gastric bypass (RYGB) between August 2005 and March 2008. Three-day dietary intake was recorded at baseline (n=24), at 2 weeks (n=16), 3 months (n=11), and 1 year (n=9) post-operatively. Dietary record data were verified by structured interview and compared with Dietary Reference Intake (DRI) values for ages 14–18. Results By 1 year post-surgery, mean caloric intake adjusted for BMI was 1015 ± 182 kcal/day, a 35% reduction from baseline. The proportion of fat, protein and carbohydrate intake did not differ from baseline. However, protein intake was lower than recommended postoperatively. Calcium and fiber intake was also persistently lower than recommended. Calcium and vitamin B12 supplementation increased the likelihood of meeting daily minimal recommendations (p≤0.02). Conclusions One year after RYGB, adolescents’ caloric intake remained restricted with satisfactory macronutrient composition, but with lower than desirable intake of calcium, fiber and protein.

To assess the hormonal, metabolic and physiological effects of laparascopic surgery performed under a sedative analgesic combination of detomidine and buprenorphine in standing horses. Prospective study. Eight healthy adult Dutch Warmblood horses and five healthy adult ponies undergoing laparoscopy were studied. Five healthy adult horses not undergoing laparoscopy were used as a control group. The sedative effect of an initial detomidine and buprenorphine injection was maintained using a continuous infusion of detomidine alone. The heart and respiratory rate, arterial blood pH and arterial oxygen and carbon dioxide tensions were monitored, while blood samples were taken for the measurement of glucose, lactate, cortisol, insulin and nonesterified fatty acids (NEFA). The same variables were monitored in a control group of horses which were sedated, but which did not undergo surgery. At the end of the sedation period the effects of detomidine were antagonized using atipamezole. The protocol provided suitable conditions for standing laparoscopy in horses. Laparoscopy induced obvious metabolic and endocrine responses which, with the exception of NEFA values, were not significantly different from changes found in the control group. While atipamezole did not produce detectable adverse effects, it is possible that anatagonism may not be essential. The technique described reliably produces adequate sedation and analgesia for laparoscopic procedures. The level of sedation/analgesia was controlled by decreasing or increasing the infusion rate. Antagonism of the effects of detomidine may not be necessary in all cases. Copyright © 2003 Association of Veterinary Anaesthetists and American College of Veterinary Anesthesia and Analgesia.

Speech recognition technology is a recent development in minimally invasive surgery. This study was designed to assess the impact of HERMES on operating room efficiency and user satisfaction. Patients undergoing laparoscopic antireflux operations by surgeons experienced in minimally invasive surgery were randomized to HERMES-assisted or standard laparoscopic operations. The variables of interest were circulating nurse's time spent adjusting devices that are voice-controlled by HERMES, number of adjustments to devices requested, and surgeon and nurse satisfaction measured on a scale from 1 (dissatisfied) to 10 (satisfied). A total of 30 cases were studied. In the non-HERMES cases, nurses were interrupted to make device adjustments an average of 15.3 times per case versus 0.33 times per case in the with-HERMES cases (p < 0.01). The interruptions during the non-HERMES cases averaged 4.35 min per case versus 0.16 min per case in the with-HERMES cases (p = 0.03). Average satisfaction scores for HERMES operations as opposed to non-HERMES operations were 9.2 versus 5.3 for nurses (p < 0.01) and 9.0 versus 5.1 for surgeons (p < 0.01). Physician and nurse acceptance of HERMES was very high because of the smoother interruption-free environment.

A carbohydrate-rich drink (CHO) has been shown to reduce preoperative discomfort. It was hypothesized that it may also reduce postoperative nausea and vomiting (PONV). Patients undergoing elective laparoscopic cholecystectomy under inhalational anaesthesia (127 women and 45 men; mean(s.d.) 48(15) years) were randomized to either preoperative fasting, intake of CHO (50 kcal/100 ml, 290 mOsm/kg) or placebo. The non-fasting groups were double-blinded; patients ingested 800 ml of liquid on the evening before surgery and 400 ml 2 h before anaesthesia. Nausea and pain scores on a visual analogue scale (VAS) and episodes of PONV were recorded up to 24 h after surgery. The incidence of PONV was lower in the CHO than in the fasted group between 12 and 24 h after surgery (P = 0.039). Nausea scores in the fasted and placebo groups were higher after operation than before admission to hospital (P = 0.018 and P < 0.001 respectively), whereas there was no significant change in the CHO group. No intergroup differences in VAS scores were seen. The use of anaesthetics, opioids, antiemetics and intravenous fluids was similar in all groups. CHO may have a beneficial effect on PONV 12-24 h after laparoscopic cholecystectomy.

AIM: To compare quality of life (QoL) outcomes in Chinese patients after curative laparoscopic vs open surgery for rectal cancer. METHODS: Eligible Chinese patients with rectal cancer undergoing curative laparoscopic or open sphincter-preserving resection between July 2006 and July 2008 were enrolled in this prospective study. The QoL outcomes were assessed longitudinally using the validated Chinese versions of the European Organization for Research and Treatment of Cancer QLQ-C30 and QLQ-CR38 questionnaires before surgery and at 4, 8, and 12 mo after surgery. The QoL scores at the different time points were compared between the laparoscopic and open groups. A higher score on a functional scale indicated better functioning, whereas a higher score on a symptom scale indicated a higher degree of symptoms. RESULTS: Seventy-four patients (49 laparoscopic and 25 open) were enrolled. The two groups of patients were comparable in terms of sociodemographic data, types of surgery, tumor staging, and baseline mean QoL scores. There was no significant decrease from baseline in global QoL for the laparoscopic group at different time points, whereas the global QoL was worse compared to baseline beginning at 4 mo but returned to baseline by 12 mo for the open group (P = 0.019, Friedman test). Compared to the open group, the laparoscopic group had significantly better physical (89.9 ± 1.4 vs 79.2 ± 3.7, P = 0.016), role (85.0 ± 3.4 vs 63.3 ± 6.9, P = 0.005), and cognitive (73.5 ± 3.4 vs 50.7 ± 6.2, P = 0.002) functioning at 8 mo, fewer micturition problems at 4-8 mo (4 mo: 32.3 ± 4.7 vs 54.7 ± 7.1, P = 0.011; 8 mo: 22.8 ± 4.0 vs 40.7 ± 6.9, P = 0.020), and fewer male sexual problems from 8 mo onward (20.0 ± 8.5 vs 76.7 ± 14.5, P = 0.013). At 12 mo after surgery, no significant differences were observed in any functional or symptom scale between the two groups, with the exception of male sexual problems, which remained worse in the open group (29.2 ± 11.3 vs 80.0 ± 9.7, P = 0.026). CONCLUSION: Laparoscopic sphincter-preserving resection for rectal cancer is associated with better preservation of QoL and fewer male sexual problems when compared with open surgery in Chinese patients. These findings, however, should be interpreted with caution because of the small sample size of the study. PMID:23922475

Open cholecystectomy in the laparoscopic era.

As techniques in laparoscopic cholecystectomy have improved, surgeon experience of open cholecystectomy may be limited. This study examined the current indications for and techniques used in primary open cholecystectomy. Some 3100 consecutive patients undergoing elective or emergency cholecystectomy over a 5-year interval were identified from a prospective surgical audit database. Demographic, diagnostic and procedural data were examined. There were 123 (4.0 per cent) primary and 219 (7.4 per cent) converted open cholecystectomies. Some 48.0 and 45.6 per cent of patients in the primary open cholecystectomy and converted groups respectively were men, compared with 24.0 per cent of 2758 who had a successful laparoscopic procedure. Primary open cholecystectomy was employed principally for previous upper abdominal open surgery (22.7 per cent) and emergency operation for general peritonitis (19.5 per cent). The fundus-first approach was employed in 53.7 per cent of primary open procedures and 53.0 per cent of conversions, with subtotal excision in 4.9 and 13.2 per cent respectively. Primary open cholecystectomy remains a common procedure in the treatment of gallbladder disease despite the success of laparoscopic cholecystectomy. Successful outcome in difficult cases requires familiarity with specific techniques, exposure to which may be limited in current training programmes.

Robotic surgery has evolved from simple extirpative surgery to complex reconstructions even in infants. Data are lacking comparing surgical and direct costs to open approaches. We describe the feasibility, salient tips and outcomes of robot-assisted laparoscopic pyeloplasty compared to an open approach. We evaluated patients undergoing open pyeloplasty or robot-assisted laparoscopic pyeloplasty. Ten patients in each group met inclusion criteria. Mean patient age was 3.31 months in the open group and 7.3 months in the robotic group (p=0.02). Postoperative outcomes including length of stay (2.2 vs 2.1 days), estimated blood loss (6.5 vs 7.6 ml), days to regular diet (1 vs 1.1) and days to Foley catheter removal (1.3 vs 1.3) were similar between the open and robotic groups. Total operating time (199 vs 242 minutes) was significantly longer in the robotic group. Postoperative improvement in hydronephrosis was identical in both groups. Direct costs, excluding amortization, robotic cost, maintenance and depreciation, were $4,410 in the open group and $4,979 in the robotic group (p=0.10). In our preliminary experience robotic pyeloplasty in infants is feasible and safe. The immediate outcomes are similar to those of an open approach. The robotic technique in infants currently has the benefits of improved esthetic appearance, improved pain control and similar direct costs compared to the traditional open approach.

Torricelli, Fabio C M; Barbosa, Joao Arthur B A; Marchini, Giovanni S

2016-01-01

Minimally invasive surgery has been replacing the open standard technique in several procedures. Similar or even better postoperative outcomes have been described in laparoscopic or robot-assisted procedures when compared to open surgery. Moreover, minimally invasive surgery has been providing less postoperative pain, shorter hospitalization, and thus a faster return to daily activities. However, the learning curve required to obtain laparoscopic expertise has been a barrier in laparoscopic spreading. Laparoscopic surgery training laboratory has been developed to aid surgeons to overcome the challenging learning curve. It may include tutorials, inanimate model skills training (box models and virtual reality simulators), animal laboratory, and operating room observation. Several different laparoscopic courses are available with specific characteristics and goals. Herein, we aim to describe the activities performed in a dry and animal-model training laboratory and to evaluate the impact of different kinds of laparoscopic surgery training courses on surgeon’s performance. Several tasks are performed in dry and animal laboratory to reproduce a real surgery. A short period of training can improve laparoscopic surgical skills, although most of times it is not enough to confer laparoscopic expertise for participants. Nevertheless, this short period of training is able to increase the laparoscopic practice of surgeons in their communities. Full laparoscopic training in medical residence or fellowship programs is the best way of stimulating laparoscopic dissemination. PMID:27933135

The rapid expansion of laparoscopic surgery has led to the development of training methods for acquiring technical skills. The importance and complexity of laparoscopic liver surgery are arguments for developing a new integrated system of teaching, learning and evaluation, based on modern educational principles, on flexibility allowing wide accessibility among surgeons. This paper presents the development of e-learning platform designed for training in laparoscopic liver surgery and pre-planning of the operation in a virtual environment. E-learning platform makes it possible to simulate laparoscopic liver surgery remotely via internet connection. The addressability of this e-learning platform is large, being represented by young surgeons who are mainly preoccupied by laparoscopic liver surgery, as well as experienced surgeons interested in obtaining a competence in the hepatic minimally invasive surgery.

Laparoscopic aortobifemoral bypass has become an established treatment option for symptomatic aortoiliac obstructive disease at dedicated centers. Minimally invasive surgical techniques like laparoscopic surgery have often been shown to reduce expenses and increase patients' health-related quality of life. The main objective of our study was to measure quality-adjusted life years (QALYs) and costs after totally laparoscopic and open aortobifemoral bypass. This was a within trial analysis in a larger ongoing randomized controlled prospective multicenter trial, Norwegian Laparoscopic Aortic Surgery Trial. Fifty consecutive patients suffering from symptomatic aortoiliac occlusive disease suitable for aortobifemoral bypass surgery were randomized to either totally laparoscopic (n=25) or open surgical procedure (n=25). One patient dropped out of the study before surgery. We measured health-related quality of life using the EuroQol (EQ-5D-5L) questionnaire at 4 different time points, before surgery and for 6 months during follow-up. We calculated the QALYs gained by using the area under the curve for both groups. Costs were calculated based on prices for surgical equipment, vascular prosthesis and hospital stay. We found a significantly higher increase in QALYs after laparoscopic vs open aortobifemoral bypass surgery, with a difference of 0.07 QALYs, ( p =0.001) in favor of laparoscopic aortobifemoral bypass. The total cost of surgery, equipment and hospital stay after laparoscopic surgery (9,953 €) was less than open surgery (17,260 €), ( p =0.001). Laparoscopic aortobifemoral bypass seems to be cost-effective compared with open surgery, due to an increase in QALYs and lower procedure-related costs.

2016-06-01

The perioperative safety profile of clopidogrel, a potent antiplatelet agent used in the management of cardiovascular disease, is unknown, and there are no evidence-based guidelines recommending for either its interruption or continuation at this time. The aim of this study was to determine whether patients who are maintained on clopidogrel before general surgical procedures are at increased risk of perioperative bleeding complications. Patients receiving clopidogrel at the time of elective general surgery were randomized to either discontinue clopidogrel 1 week before surgery (group A) or continue clopidogrel into surgery (group B). All other antiplatelet and anticoagulant agents were discontinued before surgery. The primary end points were perioperative bleeding requiring intraoperative or postoperative transfusion of blood or blood components and bleeding-related readmission, reoperation, or mortality within 90 days of surgery. The secondary end points were perioperative myocardial infarction or cerebrovascular accidents within 90 days of surgery. Thirty-nine patients were enrolled and underwent 43 general surgical operations. Twenty-one procedures were randomized to group A and 22 to group B. The most commonly performed individual procedures were open inguinal hernia repair (23%), laparoscopic cholecystectomy (21%), open ventral hernia repair (15%), laparoscopic ventral hernia repair (11%), and laparoscopic inguinal hernia repair (9%). No perioperative mortalities, bleeding events requiring blood transfusion, or reoperations occurred. One readmission for intra-abdominal hematoma requiring percutaneous drainage occurred in each group (group A: 4.8% vs group B: 4.5%; P = 1.0). No myocardial infarctions or cerebrovascular accidents were observed or reported. The outcomes from this prospective study suggest that, patients undergoing commonly performed elective general surgical procedures can be safely maintained on clopidogrel without increased perioperative bleeding risk.

Transumbilical single incision laparoscopic surgery (SILS) is a new laparoscopic procedure in which only one transumbilical incision is made, demonstrated as a scarless procedure. Here we report a single-center preliminary experience of transumbilical single incision laparoscopic cholecystectomy (SILC) in the treatment of benign gallbladder diseases, defining a single surgeon's learning curve. A total of 80 patients underwent SILC successfully by a single experienced laparoscopic surgeon. The operation was performed following the routine LC procedure. Then the perioperative demographics were recorded and the operative time was used to define the learning curve. The study group included 27 male and 53 female patients with gallstones (56 cases), cholesterol polyps (16 cases), an adenomatous polyp (3 cases), adenomyomatosis (1 case), or complex diseases (4 cases), and all consented to undergo SILC. No patient was converted to normal LC or open surgery. There were no perioperative port-related or surgical complications. The average operative time was 46.9 ± 14.6 min. The average postoperative hospital stay was 1.8 ± 1.3 days. The learning curve of the SILC procedures for this series of selected patients confirmed that SILC is a feasible, safe, and effective approach to the treatment of benign gallbladder diseases. For experienced laparoscopic surgeons, SILC is an easy and safe procedure. Patients benefit from milder pain, a lower incidence of port-related complications, better cosmesis, and fast recovery. The SILC procedure may become another option for the treatment of benign gallbladder diseases for selected patients.

In bariatric surgery, there are no guidelines available for intraoperative fluid administration. Goal-directed fluid therapy (GDFT) is a new concept of perioperative fluid management that has been shown to improve the prognosis of patients undergoing abdominal surgery. The aim of our study is to assess the impact of the implementation of a GDFT protocol in morbidly obese patients who underwent laparoscopic sleeve gastrectomy (LSG). A before-after intervention study, in morbidly obese patients who underwent LSG, was conducted at the Obesity Unit of the General University Hospital Elche. Data from the GDFT implementation group (January 2014 to December 2015) were prospectively collected and compared with a preimplementation group (January 2012 to December 2013). Baseline demographic and comorbidity data between the two groups of patients were similar. The length of stay in the hospital was significantly shortened in GDFT group from 4.5 to 3.44 days (p < 0.001). Intraoperative fluid administration was significantly lower in the GDFT group (1002.4 vs 1687.2 ml in preimplementation group, p < 0.001). In the postoperative period, there was a statistically significant reduction in postoperative nausea and vomiting (PONV) after GDFT implementation (48 to 14.3 %, p < 0.001). Implementation of GDFT protocols can prevent intraoperative fluid overload in patients undergoing bariatric surgery. It could improve outcomes, for example decreasing PONV or even hospital stay.

Postoperative pain is less intense after laparoscopic than after open surgery. However, minimally invasive surgery is not a a pain-free procedure. Many trials have been done in adults using intraperitoneal and/or incisional local anesthetic, but similar studies have not yet been reported in the literature in children. The aim of this study was to evaluate the analgesic effect of periportal infiltration and intraperitoneal instillation of ropivacaine in children undergoing laparoscopic surgery. Thirty patients who underwent laparoscopic surgery were randomly allocated to one of three groups. Group A (n = 10) received local infiltration of port sites with 10 mL of ropivacaine. Group B (n = 10) received both an infiltration of port sites with 10 mL of ropivacaine and an intraperitoneal instillation of 10 mL of ropivacaine. Group C did not receive any analgesic treatment. The local anesthetic was always administered at the end of surgery. The degree of postoperative abdominal parietal pain, abdominal visceral pain, and shoulder pain was assessed by using a Wong-Baker pain scale and a Visual Analog Scale (VAS) at 3, 6 12, and 24 hours postoperatively. The following parameters were also evaluated: rescue analgesic treatment, length of hospital stay, and time of return to normal activities. Three hours after operation, patients had low pain scores. Six and 12 hours postoperatively, the abdominal parietal pain was significantly higher (P < 0.0005) in group C than in the other two groups, both treated with an infiltration at the trocar sites; mean intensity of abdominal visceral pain was significantly lower (P < 0.0005) in group B than in groups A and C; the overall incidence of shoulder pain was significantly lower (P < 0.0005) in group B patients than in patients of groups A and C. At 20 hours postoperatively, pain scores were significantly reduced of intensity in all groups. Rescue analgesic treatment was significantly higher in group C, if compared to groups A and B 12 hours after the operation. No statistically significant difference was found in length of hospital stay, but children who received analgesic treatment had a more rapid return to normal activities than untreated patients (P < 0.0005). Our study demonstrates that the combination of local infiltration and intraperitoneal instillation of ropivacaine is more effective for pain relief in children after laparoscopic surgery than the administration of ropivacaine only at the trocar sites.

The purpose of the present study was to compare the perioperative and oncologic outcomes between laparoscopic surgery and open surgery for transverse colon cancer. We conducted a retrospective review of patients who underwent surgery for transverse colon cancer at six Hallym University-affiliated hospitals between January 2005 and June 2015. The perioperative outcomes and oncologic outcomes were compared between laparoscopic and open surgery. Of 226 patients with transverse colon cancer, 103 underwent laparoscopic surgery and 123 underwent open surgery. There were no differences in the patient characteristics between the two groups. Regarding perioperative outcomes, the operation time was significantly longer in the laparoscopic group than in the open group (267.3 vs 172.7 minutes, P<0.001), but the time to soft food intake (6.0 vs 6.6 days, P=0.036) and the postoperative hospital stay (13.7 vs 15.7 days, P=0.018) were shorter in the laparoscopic group. The number of harvested lymph nodes was lower in the laparoscopic group than in the open group (20.3 vs 24.3, P<0.001). The 5-year overall survival (90.8% vs 88.6%, P=0.540) and disease-free survival (86.1% vs 78.9%, P=0.201) rates were similar in both groups. The present study showed that laparoscopic surgery is associated with several perioperative benefits and similar oncologic outcomes to open surgery for the resection of transverse colon cancer. Therefore, laparoscopic surgery offers a safe alternative to open surgery in patients with transverse colon cancer.

Laparoscopic Heller myotomy is the most effective therapy for achalasia. All case series have reported a minimum length of stay of more than 1 day. "True" day-case laparoscopic Heller myotomy has not been reported, so far. The aim of this study was to review our results with laparoscopic Heller myotomy with respect to the length of stay following the procedure. All patients undergoing laparoscopic Heller myotomy between August 2000 and July 2007 under the care of one surgeon were included in the study. This was performed by incising 6 cm of distal esophageal musculature, extending to 2 cm below the gastroesophageal junction. The myotomy was covered by an anterior fundoplication. All patients were reviewed in the clinic at a median of 6 weeks after surgery and, thereafter, if necessary. Over the 7-year period, 24 consecutive patients with achalasia were treated in this manner. There were 13 women and 11 men, with an age range of 12-73 years. Intraoperative complications included mucosal perforation in 2 patients (sutured immediately) with no postoperative complications or conversion to open surgery. There were no deaths. The average length of stay was 1.9 days (range, 0-4). The last 2 patients were discharged on the same day, and the 5 previous to this were discharged within 23 hours of surgery. There were no adverse outcomes related to early discharge, and there were no readmissions. All patients reported good to excellent results with a relief of dysphagia on follow-up. Three patients (12%) developed recurrent dysphagia after an initial improvement, requiring dilatation only several months later. Based on our own experience, we believe that laparoscopic Heller myotomy with anterior partial fundoplication is safe and achieves a good outcome in the treatment of achalasia. It is well tolerated and can be considered a true day-case procedure.

Surgical site infections (SSIs) are frequent complications in colorectal surgery and may lead to burst abdomen, incisional hernia, and increased perioperative costs. Plastic wound ring drapes (RD) were introduced some decades ago to protect the abdominal wound from bacteria and reduce SSIs. There have been no controlled trials examining the benefit of RD in laparoscopic colorectal surgery. The Reduction of wound infections in laparoscopic assisted colorectal resections by plastic wound ring drapes (REDWIL) trial was thus designed to assess their effectiveness in preventing SSIs after elective laparoscopic colorectal resections. REDWIL is a randomized controlled monocenter trial with two parallel groups (experimental group with RD and control group without RD). Patients undergoing elective laparoscopic colorectal resection were included. The primary endpoint was SSIs. Secondary outcomes were colonization of the abdominal wall with bacteria, reoperations/readmissions, early/late postoperative complications, and cost of hospital stay. The duration of follow-up was 6 months. Between January 2008 and October 2010, 109 patients were randomly assigned to the experimental or control group (with or without RD). Forty-six patients in the RD group and 47 patients in the control group completed follow-up. SSIs developed in ten patients with RD (21.7 %) and six patients without RD (12.8 %) (p = 0.28). An intraoperative swab taken from the abdominal wall was positive in 66.7 % of patients with RD and 57.5 % without RD (p = 0.46). The number of species cultured within one swab was significantly higher in those without RD (p = 0.03). The median total inpatient costs including emergency readmissions were 3,402 ± 4,038 in the RD group and 3,563 ± 1,735 in the control group (p = 0.869). RD do not reduce the rate of SSIs in laparoscopic colorectal surgery. The inpatient costs are similar with and without RD.

Laparoscopic technology is gradually accepted in gastric cancer surgery, whose efficacy has been demonstrated by some clinical researches. Randomized controlled trials (RCT) are considered as the most important evidence to prove clinical outcomes of laparoscopic surgery for gastric cancer. Korean gastric surgeons have made great contributions to RCT in laparoscopic gastric cancer surgery. KLASS (Korean Laparoscopic Gastrointestinal Surgery Study Group) is one of the most important forerunner and global leader of clinical trials of gastric cancer treatment. KLASS series clinical trials are attracting global attention because of the significant value of surgical treatment for gastric cancer. The RCTs in Korea involve in many aspects of laparoscopic gastrectomy for gastric cancer, including laparoscopy application in early gastric cancer (KLASS-01, KLASS-03 and KLASS-07), advanced gastric cancer (KLASS-02 and KLASS-06), function-preserving gastrectomy (KLASS-04,KLASS-05) and sentinel node navigation surgery (SENORITA trial). In order to share some informations of these RCTs, we review and prospect some important clinical trials of laparoscopic gastric cancer surgery in Korea. With the experience of Korean gastric surgeons, we can make more progress in our own clinical trials of laparoscopic gastric cancer surgery.

To compare the cost efficacy ratios of medical therapy (methotrexate - MTX) and laparoscopic surgery for ectopic pregnancy, based on an observational study of effectiveness. Data were collected by a population register of the Auvergne area. We computed the costs before, during and after hospitalization of women who could be treated either by MTX or laparoscopic surgery. We detailed costs related to the various existing facilities. We considered the entire treatment. One hundred nine cases of ectopic pregnancy were treated by laparoscopic surgery and 46 by MTX. Second-line therapy was required in 3% of women who underwent laparoscopic surgery, and 35% of those given MTX. MTX was found to be less costly (1,342 euros) than laparoscopic surgery (2,113 euros). The efficacy threshold for MTX was 11% (giving a failure rate of 89%). MTX is much more cost effective than laparoscopic surgery but the frequent need for second-line treatment must also be assessed.

Due to the current economic crisis in Greece, major cutbacks on healthcare costs have been imposed, resulting in a shortage of surgical supplies, including laparoscopic materials. In an attempt to reduce costs, we developed a homemade specimen retrieval bag for laparoscopic cholecystectomy. We used the polyethylene bag containing the catheter of a Redon drainage set. The bag was cut in half and pleated longitudinally; then, the gallbladder was placed in the bag and removed through the umbilicus with a grasping forceps. From September 2011 to June 2012, we used our homemade bag on 85 patients undergoing laparoscopic cholecystectomy. No rupture, accidental opening, or bile leak was observed. The learning curve was found to be five cases. Our homemade specimen retrieval bag seems to be a safe, effective, and easy tool for tissue extraction. Further studies need to be conducted to evaluate its full potential. © 2015 Japan Society for Endoscopic Surgery, Asia Endosurgery Task Force and Wiley Publishing Asia Pty Ltd.

The use of oral prophylactic antibiotics for the prevention of surgical-site infection (SSI) in patients undergoing laparoscopic surgery for colorectal cancer is controversial. The aim of this RCT was to evaluate whether intravenous perioperative antibiotics are inferior to combined preoperative oral and perioperative intravenous antibiotics in this setting. Patients undergoing elective laparoscopic colorectal resection in a single cancer centre were assigned randomly to combined preoperative oral antibiotics (metronidazole and kanamycin) and perioperative intravenous antibiotics (cefmetazole) (oral/IV group) or to perioperative intravenous antibiotics (cefmetazole) alone (IV-only group). Patients were stratified for the analyses based on type of operation (colonic surgery, anterior resection or abdominoperineal resection), preoperative use of mechanical bowel preparation, preoperative chemoradiotherapy and the presence of diabetes mellitus. The primary endpoint was the overall rate of SSI. Secondary endpoints were the rates of incisional site infection, organ/space infection, anastomotic leakage, intra-abdominal abscess, adverse events and postoperative complications. Of 540 patients offered participation in the trial in 2013-2014, 515 agreed to take part and were randomized. Some 256 patients in the IV-only group and 255 in the oral/IV group completed the treatment per protocol. The overall rate of SSI was 7·8 per cent (20 of 256) in the IV-only group and 7·8 per cent (20 of 255) in the oral/IV group, confirming that perioperative administration of intravenous antibiotics alone was not inferior to the combined regimen (P = 0·017). There were no differences in rates of incisional site infection (5·5 versus 5·9 per cent respectively), organ/space infection (2·3 versus 2·0 per cent) or other secondary endpoints between the two groups. Intravenous perioperative antimicrobial prophylaxis alone is not inferior to combined preoperative oral and intravenous perioperative prophylaxis with regard to SSI in patients with colorectal cancer undergoing elective laparoscopic resection.

Impact of Weight Loss Surgery on Esophageal Physiology

PubMed Central

Naik, Rishi D.; Choksi, Yash A.

2015-01-01

Bariatric surgery has come to the forefront of weight loss treatment due to its complex interactions via anatomic, physiologic, and neurohormonal changes leading to sustained weight loss. Unlike lifestyle and pharmacologic options, which fail to show long-term sustained weight loss, bariatric surgery has been shown to decrease overall mortality and morbidity. Bariatric surgery can be purely restrictive, such as laparoscopic adjustable gastric band (LAGB) or laparoscopic sleeve gastrectomy (LSG), or restrictive-malabsorptive, such as Roux-en-Y gastric bypass (RYGB). These surgeries cause specific anatomic changes that promote weight loss; however, they also have unintended effects on the esophagus, particularly in terms of gastroesophageal reflux disease (GERD) and esophageal motility. Via restrictive surgery, LAGB has been widely reported to cause significant weight loss, although studies have also shown an increase and worsening of GERD as well as elevated rates of esophageal dilation, aperistalsis, and alterations in lower esophageal sphincter pressure. Along with LAGB, LSG has shown not only a worsening of GERD, but also the formation of de novo GERD in patients who were asymptomatic before the operation. In a restrictive-malabsorptive approach, RYGB has been reported to improve GERD and preserve esophageal motility. Bariatric surgery is a burgeoning field with immense implications on overall mortality. Future randomized, controlled trials are needed to better understand which patients should undergo particular surgeries, with greater emphasis on esophageal health and prevention of GERD and esophageal dysmotility.

2012-06-01

Excisional surgery for choledochal malformations in Scotland is currently performed in three specialist pediatric surgical centers using open or laparoscopic-assisted techniques. We reviewed the outcome of children who had excisional surgery in Scotland between 1992 and 2010. Case notes for all patients undergoing excisional surgery in any of the three specialist pediatric surgical centers in Scotland between 1992 and 2010 were retrospectively reviewed. A total of 25 patients were identified, with a female preponderance of 4:1. Of these, three patients (12%) were diagnosed by antenatal ultrasound scan. The commonest presenting symptoms were anorexia (56%), abdominal pain (52%), and jaundice (52%). Only 20% had the classical triad of abdominal pain, jaundice, and a palpable mass. Using the King's College Hospital classification, 14 patients had type 1 malformations, 8 had type 4 malformations, and 3 had type 2 malformations. Median age at operation was 2 years (range 35 days to 13.5 years). Two centers performed open excision while the third center used primarily a laparoscopic-assisted technique. Median follow-up was 2.1 years (range 30 days to 11.9 years). Three patients (12%) required repeat laparotomy. The wound infection rate was 8% (n=2). The recurrent cholangitis rate was 8% (n=2). There was one late death due to adhesive small bowel obstruction, 4 years after surgery. To date, no patient has developed biliary tree stones or liver failure. Choledochal malformation excisional surgery, either open or laparoscopic assisted, can be safely performed in appropriately equipped, pediatric surgical centers in Scotland by experienced pediatric surgeons.

The treatment of rectal cancer via laparoscopy is controversial due to its technical complexity. Several randomized prospective studies have demonstrated clear advantages for the patient with similar oncological results to those of open surgery, although during the learning of this surgical technique there may be an increase in complications and a worse prognosis. Our aim is to analyze how the learning curve for rectal cancer via laparoscopy influences intra- and postoperative results and oncological markers. A retrospective review was conducted of the first 120 patients undergoing laparoscopic surgery for rectal neoplasia. The operations were performed by the same surgical team with a wide experience in the treatment of open colorectal cancer and qualified to perform advanced laparoscopic surgery. We analyzed sex, ASA, tumour location, neoadjuvant treatment, surgical technique, operating time, conversion, postoperative complications, length of hospital stay, number of lymph nodes, stage and involvement of margins. Significant differences were observed with regard to surgical time (224 min in the first group, 204 min in the second group), with a higher rate of conversion in the first group (22.5%) than in the second (11.3%). No significant differences were noted for rate of conservative sphincter surgery, length of hospital stay, post-surgical complications, number of affected/isolated lymph nodes or affected circumferential and distal margins. It is possible to learn this complex surgical technique without compromising the patient's safety and oncological outcome. Copyright © 2013 AEC. Published by Elsevier Espana. All rights reserved.

Transrectal Mesh Erosion Requiring Bowel Resection.

Kemp, Marta Maria; Slim, Karem; Rabischong, Benoît; Bourdel, Nicolas; Canis, Michel; Botchorishvili, Revaz

To report a case of a transrectal mesh erosion as complication of laparoscopic promontofixation with mesh repair, necessitating bowel resection and subsequent surgical interventions. Sacrocolpopexy has become a standard procedure for vaginal vault prolapse [1], and the laparoscopic approach has gained popularity owing to more rapid recovery and less morbidity [2,3]. Mesh erosion is a well-known complication of surgical treatment for prolapse as reported in several negative evaluations, including a report from the US Food and Drug Administration in 2011 [4]. Mesh complications are more common after surgeries via the vaginal approach [5]; nonetheless, the incidence of vaginal mesh erosion after laparoscopic procedures is as high as 9% [6]. The incidence of transrectal mesh exposure after laparoscopic ventral rectopexy is roughly 1% [7]. The diagnosis may be delayed because of its rarity and variable presentation. In addition, polyester meshes, such as the mesh used in this case, carry a higher risk of exposure [8]. A 57-year-old woman experiencing genital prolapse, with the cervix classified as +3 according to the Pelvic Organ Prolapse Quantification system, underwent laparoscopic standard sacrocolpopexy using polyester mesh. Subtotal hysterectomy and bilateral adnexectomy were performed concomitantly. A 3-year follow-up consultation demonstrated no signs or symptoms of erosion of any type. At 7 years after the surgery, however, the patient presented with rectal discharge, diagnosed as infectious rectocolitis with the isolation of Clostridium difficile. She underwent a total of 5 repair surgeries in a period of 4 months, including transrectal resection of exposed mesh, laparoscopic ablation of mesh with digestive resection, exploratory laparoscopy with abscess drainage, and exploratory laparoscopy with ablation of residual mesh and transverse colostomy. She recovered well after the last intervention, exhibiting no signs of vaginal or rectal fistula and no recurrence of pelvic floor descent. Her intestinal transit was reestablished, and she was satisfied with the treatment. None of the studies that represent the specific female population submitted to laparoscopic promontofixation with transrectal mesh erosion describe the need for more than one intervention or digestive resection [9-12]. Physicians dealing with patients submitted to pelvic reconstructive surgeries with mesh placement should be aware of transrectal and other nonvaginal erosions of mesh, even being rare events. Moreover, they should perform an active search for unusual gynecologic and anorectal signs and symptoms. Most importantly, patients undergoing mesh repair procedures must be warned of the risks of the surgery, including the possibility of several subsequent interventions. Copyright © 2017 AAGL.

Objectives: Benign paroxysmal positional vertigo is a common vestibular disorder and it may be idiopathic or secondary to some conditions such as surgery, but rare following laparoscopic surgery. Methods: We report two cases of benign paroxysmal positional vertigo secondary to laparoscopic surgery, one after laparoscopic cholecystectomy in a 51-year-old man and another following laparoscopic hysterectomy in a 60-year-old woman. Results: Both patients were treated successfully with manual or device-assisted canalith repositioning maneuvers, with no recurrence on the follow-up of 6 -18 months. Conclusions: Benign paroxysmal positional vertigo is a rare but possible complication of laparoscopic surgery. Both manual and device-assisted repositioning maneuvers are effective treatments for this condition, with good efficacy and prognosis. PMID:28255446

2016-01-01

Unexplained abdominal pain is a common but difficult presenting feature faced by the clinicians. Such patients can undergo a number of investigations with failure to reach any diagnosis. The objective of this study was to evaluate the use of laparoscopy in the diagnosis and management of patients with unexplained abdominal pain. This cross-sectional study was conducted at Pakistan Institute of Medical Sciences Islamabad from January 2009 to December 2013. This study included 91 patients of unexplained abdominal pain not diagnosed by routine clinical examination and investigations. These patients were subjected to diagnostic laparoscopy for evaluation of their conditions and to confirm the diagnosis. These patients presented 43% of patients undergoing investigations for abdominal pain. Patients diagnosed with gynaecological problems were excluded to see surgeon's perspective. The findings and the outcomes of the laparoscopy were recorded and data was analyzed. Unexplained abdominal pain is common in females than in males. The most common laparoscopic findings were abdominal tuberculosis followed by appendicitis. Ninety percent patients achieved pain relief after laparoscopic intervention. Laparoscopy is both beneficial and safe in majority of patients with unexplained abdominal pain. General surgeons should acquire training and experience in laparoscopic surgery to provide maximum benefit to these difficult patients.

Objective To assess the use of laparoscopic surgeries (LS) and the association between its performance and hospitals’ preference for LS over open surgeries. Summary background data LS is increasingly used in many abdominal surgeries, albeit both with and without solid guideline recommendations. To date, the hospitals’ preference (LS vs. open surgeries) and its association with in-hospital outcomes has not been evaluated. Methods We enrolled patients undergoing 8 types of gastrointestinal surgeries in 2011–2013 in the Japanese National Clinical Database. We assessed the use of LS and the occurrences of surgery-related morbidity and mortality during the study period. Further, for 4 typical LS procedures, we assessed the hospitals’ preference for LS by modeling the propensity to perform LS (over open surgeries) from patient-level factors, and estimating each institution’s observed/expected (O/E) ratio for LS use. Institutions with O/E>2 were defined as LS-dominant. Using hierarchical logistic regression models, we assessed the association between LS preference and in-hospital outcomes. Results Among 1,377,118 patients undergoing gastrointestinal procedures in 2,336 participating hospitals, use of LS increased in all 8 procedures (35.1% to 44.7% for distal gastrectomy (DG), and 27.5% to 43.2% for right hemi colectomy (RHC)). Those operated at LS-dominant hospitals were at an increased risk of operative death (OR 1.83 [95%CI, 1.37–2.45] for DG, 1.79 [95%CI, 1.43–2.25] for RHC) compared to standard O/E level hospitals (0.5≤O/E<2.0). Conclusions LS use widely increased during 2011–2013 in Japan. Facilities with higher than expected LS use had higher mortality compared to other hospitals, suggesting a need for careful patient selection and dissemination of the procedure. PMID:29505561

This work is a topic highlight on the surgical treatment of the right colon pathologies, focusing on the literature state of art and comparing the open surgery to the different laparoscopic and robotic procedures. Different laparoscopic procedures have been described for the treatment of right colon tumors: Totally laparoscopic right colectomy, laparoscopic assisted right colectomy, laparoscopic facilitated right colectomy, hand-assisted right colectomy, single incision laparoscopic surgery colectomy, robotic right colectomy. Two main characteristics of these techniques are the different type of anastomosis: Intracorporeal (for totally laparoscopic right colectomy, single incision laparoscopic surgery colectomy, laparoscopic assisted right colectomy and robotic technique) or extracorporeal (for laparoscopic assisted right colectomy, laparoscopic facilitated right colectomy, hand-assisted right colectomy and open right colectomy) and the different incision (suprapubic, median or transverse on the right side of abdomen). The different laparoscopic techniques meet the same oncological criteria of radicalism as the open surgery for the right colon. The totally laparoscopic right colectomy with intracorporeal anastomosis and even more the single incision laparoscopic surgery colectomy, remain a technical challenge due to the complexity of procedures (especially for the single incision laparoscopic surgery colectomy) and the particular right colon vascular anatomy but they seem to have some theoretical advantages compared to the other laparoscopic and open procedures. Data reported in literature while confirming the advantages of laparoscopic approach, do not allow to solve controversies about which is the best laparoscopic technique (Intracorporeal vs Extracorporeal Anastomosis) to treat the right colon cancer. However, the laparoscopic techniques with intracorporeal anastomosis for the right colon seem to show some theoretical advantages (functional, technical, oncological and cosmetic advantages) even if all studies conclude that further prospective randomized trials are necessary. Robotic technique may be useful to overcome the problems related to inexperience in laparoscopy in some surgical centers. PMID:27648160

Medical software can build a digital clone of the patient with 3-dimensional reconstruction of Digital Imaging and Communication in Medicine images. The virtual clone can be manipulated (rotations, zooms, etc), and the various organs can be selectively displayed or hidden to facilitate a virtual reality preoperative surgical exploration and planning. We present preliminary cases showing the potential interest of virtual reality in colorectal surgery for both cases of diverticular disease and colonic neoplasms. This was a single-center feasibility study. The study was conducted at a tertiary care institution. Two patients underwent a laparoscopic left hemicolectomy for diverticular disease, and 1 patient underwent a laparoscopic right hemicolectomy for cancer. The 3-dimensional virtual models were obtained from preoperative CT scans. The virtual model was used to perform preoperative exploration and planning. Intraoperatively, one of the surgeons was manipulating the virtual reality model, using the touch screen of a tablet, which was interactively displayed to the surgical team. The main outcome was evaluation of the precision of virtual reality in colorectal surgery planning and exploration. In 1 patient undergoing laparoscopic left hemicolectomy, an abnormal origin of the left colic artery beginning as an extremely short common trunk from the inferior mesenteric artery was clearly seen in the virtual reality model. This finding was missed by the radiologist on CT scan. The precise identification of this vascular variant granted a safe and adequate surgery. In the remaining cases, the virtual reality model helped to precisely estimate the vascular anatomy, providing key landmarks for a safer dissection. A larger sample size would be necessary to definitively assess the efficacy of virtual reality in colorectal surgery. Virtual reality can provide an enhanced understanding of crucial anatomical details, both preoperatively and intraoperatively, which could contribute to improve safety in colorectal surgery.

Postoperative insulin resistance, used as a marker of stress response, is clearly an adverse event. It may induce postoperative hyperglycemia, which according to some authors can increase the risk of postoperative complications. One of the elements of modern perioperative care is preoperative administration of oral carbohydrate loading (CHO-loading), which shortens preoperative fasting and reduces insulin resistance. The aim of the study is to establish the influence of CHO-loading on the level of insulin resistance and cortisol in patients undergoing elective laparoscopic cholecystectomy. Patients were randomly allocated to one of 2 groups. The intervention group included 20 patients who received CHO-loading (400 ml Nutricia pre-op®) 2 hours prior surgery. The control group received a placebo (clear water). In every patient blood samples were taken 2 hours prior to surgery, immediately after surgery, and on the 1st postoperative day. Levels and changes in glucose, cortisol and insulin resistance were analyzed in both groups. Although there were differences in the levels of cortisol, insulin, and insulin resistance, no statistically significant differences were observed between groups in every measurement. The length of stay and postoperative complications were comparable in both groups. We believe that CHO-loading is not clinically justified in case of laparoscopic cholecystectomy. No effect on the levels of glucose, insulin resistance and cortisol was observed. Even though such procedure is safe, in our opinion there is no clinical benefit from CHO-loading prior to laparoscopic cholecystectomy.

Introduction Laparoscopic sleeve gastrectomy (LSG) and laparoscopic adjustable gastric banding (LAGB) are acceptable options for primary bariatric procedures in patients with body mass index (BMI) 35–55 kg/m2. Aim The aim of this study is to compare the effects of these two bariatric procedures 6, 12 and 24 months after surgery. Material and methods Two hundred and two patients were included 72 LSG and 130 LAGB patients. The average age was 38.8 ±11.9 and 39.4 ±10.4 years in LSG and LAGB groups, with initial BMI of 44.1 kg/m2 and 45.2 kg/m2, p = NS. Results The mean percentage of excess weight loss (%EWL) at 6 months for LSG vs. LAGB was 36.3% vs. 30.1% (p = 0.01) and at 12 months was 43.8% vs. 34.6% (p = 0.005). The greatest difference in the mean %EWL at 12 months was observed in patients with initial BMI of 40–49.9 kg/m2 in favor of LSG (47.5% vs. 35.6%; p = 0.01). Two years after surgery there was no advantage of LSG and in the subgroup of patients with BMI 50–55 kg/m2 there was a trend in favor of LAGB (57.2% vs. 30%; p = 0.07). The multiple regression model of independent variables (age, gender, initial BMI and the presence of comorbidities) proved insignificant in prediction of the best outcome in means of %EWL for either operative modality. None of these factors in the logistic regression model could determine the type of surgery that should be used in particular patients. Conclusions During the first 2 years after surgery, the best results were obtained in women with lower BMI undergoing LSG surgery. The LSG provides greater %EWL after a shorter period of time though the difference decreases in time. PMID:25337157

Laparoscopic common bile duct exploration (CBDE) is becoming more popular in the management of choledocholithiasis due to improved laparoscopic expertise and advancement in endoscopic technology and equipment. This study aimed to evaluate the safety and short-term outcome of laparoscopic CBDE in a single institution over a 3-year period. A retrospective review of the records of all patients who underwent laparoscopic CBDE in Tan Tock Seng Hospital between January 2006 and September 2008 was conducted. Fifty consecutive patients, with a median age of 60 years (range, 27 to 85) underwent laparoscopic CBDE for choledocholithiasis during the study period. About half of our patients presented as an emergency with acute cholangitis (32.0%) accounting for the majority. A total of 22 (44.0%) patients underwent laparoscopic CBDE as their primary procedure while the remaining 28 (56.0%) were subjected to preoperative ERCP initially. Of the latter group, documented stone clearance was only documented in 5 (17.9%) patients. Laparoscopic CBDE via the transcystic route was performed in 27 (54.0%) patients while another 18 patients (36.0%) had laparoscopic choledochotomy and 1 patient (2.0%) had laparoscopic choledocho-duodenostomy. There were 4 (8.0%) conversions in our series. The median operative time for laparoscopic CBDE via the transcystic route and the laparoscopic choledochotomy were 170 (75-465) and 250 (160-415) minutes, respectively. For the 18 patients who underwent a laparoscopic choledochotomy, T-tube was inserted in 8 (44.4%) patients while an internal biliary stent was placed in 4 (22.2%) with the remaining 6 patients (33.3%) undergoing primary closure of the choledochotomy. The median length of hospital stay was 2 days (range, 1 to 15) with no associated mortality. The main complications (n = 4, 8.0%) included retained CBD stones and biliary leakage. These were treated successfully with postoperative endoscopic retrograde cholangiopancreatography (ERCP) with/without percutaneous drainage with no further surgery required. Laparoscopic CBDE is a safe operation with good outcome in managing choledocholithasis. Its dividends include the numerous benefits of minimally invasive surgery. If possible, transcystic extraction is preferred to choledochotomy, as this obviates the need for biliary diversion. ERCP will still hold an important role in certain instances in the management of choledocholithiasis.

Laparoscopic procedures are generally thought to have better outcomes than open procedures. Because of anatomical constraints, laparoscopic rectal resection may not be better because of limitations in performing an adequate cancer resection. To determine whether laparoscopic resection is noninferior to open rectal cancer resection for adequacy of cancer clearance. Randomized, noninferiority, phase 3 trial (Australasian Laparoscopic Cancer of the Rectum; ALaCaRT) conducted between March 2010 and November 2014. Twenty-six accredited surgeons from 24 sites in Australia and New Zealand randomized 475 patients with T1-T3 rectal adenocarcinoma less than 15 cm from the anal verge. Open laparotomy and rectal resection (n = 237) or laparoscopic rectal resection (n = 238). The primary end point was a composite of oncological factors indicating an adequate surgical resection, with a noninferiority boundary of Δ = -8%. Successful resection was defined as meeting all the following criteria: (1) complete total mesorectal excision, (2) a clear circumferential margin (≥1 mm), and (3) a clear distal resection margin (≥1 mm). Pathologists used standardized reporting and were blinded to the method of surgery. A successful resection was achieved in 194 patients (82%) in the laparoscopic surgery group and 208 patients (89%) in the open surgery group (risk difference of -7.0% [95% CI, -12.4% to ∞]; P = .38 for noninferiority). The circumferential resection margin was clear in 222 patients (93%) in the laparoscopic surgery group and in 228 patients (97%) in the open surgery group (risk difference of -3.7% [95% CI, -7.6% to 0.1%]; P = .06), the distal margin was clear in 236 patients (99%) in the laparoscopic surgery group and in 234 patients (99%) in the open surgery group (risk difference of -0.4% [95% CI, -1.8% to 1.0%]; P = .67), and total mesorectal excision was complete in 206 patients (87%) in the laparoscopic surgery group and 216 patients (92%) in the open surgery group (risk difference of -5.4% [95% CI, -10.9% to 0.2%]; P = .06). The conversion rate from laparoscopic to open surgery was 9%. Among patients with T1-T3 rectal tumors, noninferiority of laparoscopic surgery compared with open surgery for successful resection was not established. Although the overall quality of surgery was high, these findings do not provide sufficient evidence for the routine use of laparoscopic surgery. Longer follow-up of recurrence and survival is currently being acquired. anzctr.org Identifier: ACTRN12609000663257.

To study the effects of the wide excision of soft tissues adjacent to the ovary and fallopian tube on ovarian function and surgical outcomes in women undergoing laparoscopic bilateral prophylactic salpingectomy. Randomized, controlled trial. Teaching hospital. One hundred eighty-six women undergoing laparoscopic surgery for uterine myoma (n = 143) or tubal surgical sterilization (n = 43). Patients were randomly divided into two groups. In group A (n = 91), standard salpingectomy was performed. In group B (n = 95), the mesosalpinx was removed within the tubes. Prior to and 3 months after surgery, antimüllerian hormone (AMH), FSH, three-dimensional antral follicle count (AFC), vascular index (VI), flow index (FI), vascular-flow index (VFI), and OvAge were recorded for each patient. Ovarian reserve modification (Δ) before and after surgery was assessed as the primary outcome. Operative time, variation of the hemoglobin level (ΔHb), postoperative hospital stay, postoperative return to normal activity, and complication rate were assessed as secondary outcomes. No significant difference was observed between groups for ΔAMH, ΔFSH, ΔAFC, ΔVI, ΔFI, ΔVFI, and ΔOvAge. Moreover, the groups were similar for operative time, ΔHb, postoperative hospital stay, postoperative return to normal activity, and complication rate. Even when the surgical excision includes the removal of the mesosalpinx, salpingectomy does not damage the ovarian reserve. Moreover, wide salpingectomy with excision of the mesosalpinx did not alter blood loss, hospitalization stay, or return to normal activities. NCT02086370.

Background. The incidence of inflammatory bowel disease (IBD) is increasing in the paediatric population. Since 2007, a single surgeon whose main practice is in the treatment of adults has performed surgery for IBD in adults and children within two dedicated multidisciplinary teams. Our aim was to assess and compare outcomes for adults and children following surgery for IBD. Methods. Analysis of a prospectively collected database was carried out to include all patients who had undergone resectional surgery for IBD between 2007 and 2012. Results. 48 adults and 30 children were included in the study. Median age for children was 14 years (range 8-16) and for adults was 33.5 years (range 17-64). Median BMI was 23 (range 18-38) and 19 (range 13-29.5) in adults and children, respectively (P < 0.001). Laparoscopic resection was performed in 27 (90%) children and 36 (75%) adults. Postoperative complication rates were comparable, 11 (23%) in adults versus 6 (20%) in children (P = 1.00). Conclusion. Resectional surgery for IBD in children has outcomes that compare favourably with the adult population, with the majority of cases being performed by a laparoscopic approach.

Concern has been voiced that general surgery residents who train at institutions that also offer advanced laparoscopic fellowships may receive inadequate advanced laparoscopic operative experience. The purpose of our study was to compare the operative experience of general surgery residents who graduated from our institution before initiation of an advanced laparoscopic fellowship with the experience of those who graduated after the fellowship began. Operative case logs of surgery residents who graduated from 2000 through 2007 and of advanced laparoscopic fellows from 2004 through 2007 were reviewed. Surgery resident experience with basic and nonbariatric advanced laparoscopic cases during the 4 years before the fellowship was compared with the experience during the 4 years after the fellowship began. Residents who graduated before 2004 performed a mean of 140.5 +/- 19.4 basic and 77.0 +/- 17.8 advanced laparoscopic cases during their 5-year residency, compared with 193.3 +/- 34.5 basic (p = 0.003) and 113.3 +/- 23.5 advanced cases (p = 0.005) performed by those who graduated in 2004 or later. The number of nonbariatric advanced laparoscopic cases performed by each graduating surgical resident during the chief year ranged from 26 to 47 cases from 2000 to 2003 and from 36 to 69 cases from 2004 to 2007. Fellows reported from 40 to 85 nonbariatric advanced laparoscopic cases annually. General surgery residents did not experience a reduction in the total number of basic and nonbariatric advanced laparoscopic cases with the addition of an advanced laparoscopic fellowship, nor did they perform fewer cases during the chief year. As the result of a cooperative venture between the surgery residency and fellowship directors as well as an expansion of the total number of laparoscopic cases performed at our institution because of changes in clinical practice, surgery residents reported an increase in the number of laparoscopic cases while a successful fellowship was established.

To asses the role of laparoscopic appendectomy in the treatment of acute as well as chronic appendicitis on the basis of our own experiences. From the set of 849 patients treated with appendectomy (from January 1993 to December 2000) 331 were singled out, i.e.; those unable to work for some time and thus being on sickness benefit who asked for a medical certificate. They were operated on for either acute or chronic appendicitis. In our set of 331 patients (158 males, 173 females, the average age 29.4) open appendectomy was performed on 179 patients and laparoscopic appendectomy on 152. Laparoscopic appendectomy was performed in 43 males (28%) and 109 females (72%); open appendectomy in 115 males (64%) and 64 females (36%). Laparoscopic appendectomy took 53.7 +/- 18.1 minutes, open appendectomy took 43.6 +/- 8.99 minutes. The time of work disablement is longer in open appendectomy (open appendectomy: 41.2 +/- 9.91 days; laparoscopic appendectomy; 29.1 +/- 15.11 days). A significant difference (p < 0.00001) can be seen in the length of hospitalization (laparoscopic appendectomy: 5.0 +/- 2.75 days, open appendectomy: 8.3 +/- 2.83 days). Patients who undergo laparoscopic appendectomy spent less time in hospital, and they can return to work rather earlier. On the other hand the time of surgery is longer. Higher cost is compensated for with shorter hospitalization and early return to work.

Neuraxial anesthesia in upper abdominal laparoscopic surgery decreases perioperative morbidity and mortality. However, shoulder pain is common and difficult to control. Use of a major opioid (e.g., fentanyl) for the control of this event may depress respiratory function. This is why we believe that a safe and effective therapeutic control of this disease pain is a multimodal analgesic scheme which we have called infusional therapy. To compare various schemes for controlling shoulder pain secondary to pneumoperitoneum. Nonrandomized clinical trial with 56 patients ASA I-II divided into four groups undergoing laparoscopic cholecystectomy. Group I (n= 15) managed with ketorolac 1 mg kg, group II (n = 12) ketoprofen 100 mg, group III (n = 14) ketoprofen 50 mg + 50 mg tramadol, and group IV (n = 15) ketoprofen 100 mg + 100 mg tramadol. The following ariables were analyzed: presence and intensity of pain, analgesia rescue and operative time. Group I had more shoulder pain events compared to other groups (p= 0.002) in the same way the group IV required less rescue analgesia (p= 0.034). preemptive analgesia to infusional therapy with ketoprofen-tramadol at doses of 100 mg each is safe for laparoscopic surgery.

We report our technique and experience performing laparoscopic pelvic surgery on four women after transverse abdominus rectus myocutaneous flap (TRAM). Examination under anesthesia is performed on all patients in the low lithotomy position parallel with the floor. The abdominal aorta is palpated and outlined. A pneumoperitoneum is created either by umbilical or left upper quadrant Veress placement. Patients with an acceptable umbilical location undergo port placement through the incision of the umbilical relocation. Other options include left upper quadrant or paramedian placement avoiding the ligamentum teres vessels. Lateral operative ports (5 mm) are placed with reference to the transverse incision present, the pelvic pathology, and the location of the umbilicus. Techniques of electrocautery, intra- and extracorporeal suturing and knot tying, and clips are preferred to minimize port size. Following unilateral or bilateral TRAM reconstruction, four consecutive breast cancer survivors underwent successful laparoscopic-assisted vaginal hysterectomy with oophorectomy using the periumbilical incision for trocar placement. The only complication was a superficial skin breakdown from an adhesive allergy that required 6 weeks for complete resolution. Laparoscopic pelvic surgery is feasible in women after TRAM reconstruction. Knowledge of anatomic and physiologic variations related to the TRAM procedure is necessary in planning a safe operation.

The purpose of our study was to investigate surgical outcomes following advanced colorectal procedures at academic versus community institutions. The SPARCS database was used to identify patients undergoing Abdominoperineal resection (APR) and Low Anterior Resection between 2009 and 2014. Linear mixed models and generalized linear mixed models were used to compare outcomes. Laparoscopic versus open procedures, surgery type, volume status, and stoma formation between academic and community facilities were compared. Higher percentages of laparoscopic surgeries (58.68 vs. 41.32%, p value < 0.0001), more APR surgeries (64.60 vs. 35.40%, p value < 0.0001), more high volume hospitals (69.46 vs. 30.54%, p value < 0.0001), and less stoma formation (48.00 vs. 52.00%, p value < 0.0001) were associated with academic centers. After adjusting for confounding factors, academic facilities were more likely to perform APR surgeries (OR 1.35, 95% CI 1.04-1.74, p value = 0.0235). Minorities and Medicaid patients were more likely to receive care at an academic facility. Stoma formation, open surgery, and APR were associated with longer LOS and higher rate of ED visit and 30-day readmission. Laparoscopy and APR are more commonly performed at academic than community facilities. Age, sex, race, and socioeconomic status affect the facility at which and the type of surgery patients receive, thereby influencing surgical outcomes.

Background Use of transversus abdominis plane (TAP) block for postoperative analgesia is continuously increasing. However, few studies have investigated intraoperative effects of TAP block. We aimed to study the effects of TAP block in terms of cost-effectiveness and consumption of inhalation agents. Material/Methods Forty patients undergoing laparoscopic cholecystectomy were enrolled in this study. Patients were randomly divided into 2 groups: Group 1 (n=20) patients received TAP block and Group 2 (n=20) patients did not receive TAP block. Standard anesthesia induction was used in all patients. For the maintenance of anesthesia, fractional inspired oxygen (FIO2) of 50% in air with desflurane was used with a fresh gas flow of 4 L/min. All patients were monitored with electrocardiography and for peripheral oxygen saturation (SpO2), end-tidal carbon dioxide (ET), heart rate (HR), noninvasive mean blood pressure (MBP), and bispectral index (BIS). Bilateral TAP blocks were performed under ultrasound guidance to Group 1 patients. The BIS value was maintained at between 40 and 50 during the surgery. The Dion formula was used to calculate consumption of desflurane for each patient. Results There was no difference between the groups with respect to demographic characteristics of the patients. Duration of anesthesia, surgery time, and dosage of fentanyl were similar in the 2 groups. However, the cost and consumption of desflurane was significantly lower in Group 1. Conclusions Total anesthesia consumption was lower and the cost-effectiveness of anesthesia was better in TAP block patients with general anesthesia than in non-TAP block patients undergoing laparoscopic cholecystectomy.

To compare surgical costs for endometrial cancer staging between robotic-assisted and traditional laparoscopic methods. Retrospective chart review from November 2005 to July 2006 (Canadian Task Force classification II-3). Non-university-affiliated teaching hospital. Thirty-three women with diagnosed endometrial cancer undergoing hysterectomy, bilateral salpingo-oophorectomy, and pelvic and paraaortic lymph node resection. Patients underwent either robotic or traditional laparoscopic surgery without randomization. Hospital cost data were obtained for operating room time, instrument use, and disposable items from hospital billing records and provided by the finance department. Separate overall hospital stay costs were also obtained. Mean operative costs were higher for robotic procedures ($3323 vs $2029; p<.001), due in part to longer operating room time ($1549 vs $1335; p=.03). The more significant cost difference was due to disposable instrumentation ($1755 vs $672; p<.001). Total hospital costs were also higher for robotic-assisted procedures ($5084 vs $ 3615; p=.002). Robotic surgery costs were significantly higher than traditional laparoscopy costs for staging of endometrial cancer in this small cohort of patients. Copyright (c) 2010 AAGL.

Minimally invasive abdominal surgery (laparoscopy) results in superior patient outcomes compared to conventional open surgery. However, the difficulty of manipulating traditional laparoscopic tools from outside the body of the patient generally limits these benefits to patients undergoing relatively low complexity procedures. The use of tools that fit entirely inside the peritoneal cavity represents a novel approach to laparoscopic surgery. Our previous work demonstrated that miniature mobile and fixed-based in vivo robots using tethers for power and data transmission can successfully operate within the abdominal cavity. This paper describes the development of a modular wireless mobile platform for in vivo sensing and manipulation applications. Design details and results of ex vivo and in vivo tests of robots with biopsy grasper, staple/clamp, video, and physiological sensor payloads are presented. These types of self-contained surgical devices are significantly more transportable and lower in cost than current robotic surgical assistants. They could ultimately be carried and deployed by non-medical personnel at the site of an injury to allow a remotely located surgeon to provide critical first response medical intervention irrespective of the location of the patient.

Children with congenital heart disease (CHD) often require noncardiac surgery. We compared outcomes following open and laparoscopic intraabdominal surgery among children with and without CHD. We performed a retrospective cohort study using the 2013-2015 National Surgical Quality Improvement Project-Pediatrics. We matched 45,012 children <18years old who underwent laparoscopic surgery to 45,012 children who underwent open surgery. We determined the associations between laparoscopic (versus open) surgery and 30-day mortality, in-hospital mortality, 30-day morbidity, and postoperative length-of-stay. Among children with minor CHD, laparoscopic surgery was associated with lower 30-day mortality (Odds Ratio [OR] 0.34 [95% Confidence Interval 0.15-0.79]), inhospital mortality (OR 0.42 [0.22-0.81]) and 30-day morbidity (OR 0.61 [0.50-0.73]). As CHD severity increased, this benefit of laparoscopic surgery decreased for 30-day morbidity (ptrend=0.01) and in-hospital mortality (ptrend=0.05), but not for 30-day mortality (ptrend=0.27). Length-of-stay was shorter for laparoscopic approaches for children at cost of higher readmissions. On subgroup analysis, laparoscopy was associated with lower odds of postoperative blood transfusion in all children. Intraabdominal laparoscopic surgery compared to open surgery is associated with decreased morbidity in patients with no CHD and lower morbidity and mortality in patients with minor CHD, but not in those with more severe CHD.

To assess short term morbidity and renal function after robotic laparoscopic living donor nephrectomy. We performed a retrospective analysis of 100 consecutives patients undergoing a robotic laparoscopic living donors nephrectomy. We analyzed isotopic measure of the renal function before and 4 months after surgery, the side, the number of arteries, the blood loss, the operative time and warm ischemia time. In the outcomes, we collected the complications, the length of stay, and for the receiver, the renal function recovery time, dialysis, survival and renal function at one year. Left kidney nephrectomy was performed in 85 patients and we observed 25 multiples renal arteries. Mean estimated blood loss was 0,8 g/dL. Mean operative time and warm ischemia time were respectively 174 ± 30 and 4.8 ± 1.7 minutes. Seven complications occured, with 2 major (Clavien-Dindo System). Mean length of stay was 5.1 ± 1.9 days. Mean glomerular filtration decrease was 26% and remains stable at one year after surgery. Grafts had an immediate renal function recovery for 99%, and were all functional after one year, with mean MDRD clearance of 57 ± 14mL/min. Robotic procedure in laparoscopic living donor nephrectomy seems to guarantee low morbidity and the stability of the renal function decrease of 26%. Copyright © 2013.

To review the exposure pediatric surgery trainees have to laparoscopic surgery in the United Kingdom (UK). A confidential postal questionnaire was sent to all trainees working at registrar level in centers responsible for pediatric surgical training in the UK. Questions assessed the number of consultants with an interest in laparoscopic surgery, types of cases performed laparoscopically, and trainees' role in laparoscopic appendicectomy (LA). Questionnaires were sent to 112 trainees with a 55% response rate (62 replies). At least one response was received from each unit. Based on responses, 49 to 67 consultants in 21 training centers have an interest in laparoscopic surgery (0%-100% of consultants per unit). LA was offered in 20 out of 21 training centers. There was no significant difference in the proportion of appendicectomies performed laparoscopically by junior (years 1-3) and senior (years 4-6) trainees. A significantly higher proportion of junior trainees had not performed any LAs (P = 0.02). Seventy-three percent of trainees were the principal operator. For trainees who were principal operators, the cameraperson was a consultant in 52% and a junior trainee in 17%. The time of day affected the likelihood of a procedure being carried out laparoscopically in 43 (81%) responses. The majority of trainees' exposure to laparoscopic surgery could be viewed as suboptimal; however, the exposure gained varies significantly between different units throughout the UK. In an age moving in favor of minimal access surgery, all units must be in a position to offer pediatric laparoscopic surgical training.

Acupuncture is a widely serviced complementary medicine. Although acupuncture is suggested for managing postoperative ileus and pain, supporting evidence is weak. The AcuLap trial is designed to provide high-level evidence regarding whether or not electroacupuncture is effective in promoting gastrointestinal motility and controlling pain after laparoscopic surgery. This study is a prospective randomized controlled trial with a three-arm, parallel-group structure evaluating the efficacy of electroacupuncture for gastrointestinal motility and postoperative pain after laparoscopic appendectomy. Patients with appendicitis undergoing laparoscopic surgery are included and randomized into three groups: 1) electroacupuncture group, 2) sham acupuncture group, and 3) control group. Patients receive 1) acupuncture with electrostimulation or 2) fake electroacupuncture with sham device twice a day or 3) no acupuncture after laparoscopic appendectomy. The primary outcome is time to first passing flatus after operation. Secondary outcomes include postoperative pain, analgesics, nausea/vomiting, bowel motility, time to tolerable diet, complications, hospital stay, readmission rates, time to recovery, quality of life, medical costs, and protocol failure rate. Patients and hospital staff (physicians and nurses) are blinded to which group the patient is assigned, electroacupuncture or sham acupuncture. Data analysis personnel are blinded to group assignment among all three groups. Estimated sample size to detect a minimum difference of time to first flatus with 80 % power, 5 % significance, and 10 % drop rate is 29 × 3 groups = 87 patients. Analysis will be performed according to the intention-to-treat principle. The AcuLap trial will provide evidence on the merits and/or demerits of electroacupuncture for bowel motility recovery and pain relief after laparoscopic appendectomy. The trial was registered in Clinical Research Information Service (CRiS), Republic of Korea ( KCT0001486 ) on 14 May 2015.

With the growing development of minimally invasive techniques for the treatment of morbid obesity, laparoscopic bariatric surgery (LBS) is increasingly performed. This study aimed to assess the association between patients' socioeconomic status (SES) and the likelihood of undergoing LBS and related outcomes in Taiwan. This nationwide population-based study was conducted by using data from Taiwan's National Health Insurance Research Database. A total of 3678 morbidly obese patients aged 18 years and older who underwent conventional open bariatric surgery or LBS were identified between 2004 and 2011. Regression analyses were performed using generalized estimating equation (GEE) models to account for the nesting of patients within physician to assess patients' SES category associated with the use of LBS and related outcomes. Odds ratios (ORs) and 95 % confidence intervals (CIs) were estimated. Compared with those with medium and low SES (84.6 % and 80.2 %), patients with high SES (88.1 %) had the highest percentage of undergoing LBS (P < 0.001). After adjusting for patient demographics, institution and surgeon characteristics, the multivariate GEE analysis revealed that the highest likelihood of undergoing LBS was noted in morbidly obese patients with high SES (OR = 1.45, 95 % CI 1.10-1.90), followed by those with medium SES (OR = 1.27, 95 % CI 1.04-1.56). In addition, patients with high SES had slightly lower length of hospital stay (LOS; OR = 0.90, 95 % CI 0.82-0.99) and hospital treatment cost (OR = 0.93, 95 % CI 0.87-0.99) than their counterparts after adjustment. The increased likelihood of undergoing LBS and lower LOS and hospital treatment cost were noted among morbidly obese patients with higher SES. This finding suggests there is the need to improve clinical practice and reduce health disparities in the surgical treatment of morbidly obese patients.

To assess the additional effect of sudden visceral fat reduction by omentectomy on metabolic syndrome, acute-phase reactants, and inflammatory mediators in patients with grade III obesity (G-III O) undergoing laparoscopic Roux-en-Y gastric bypass (LRYGB). Twenty-two patients were randomized into two groups, LRYGB alone or with omentectomy. Levels of interleukin-6, C-reactive protein, tumor necrosis factor-alpha, leptin, adiponectin, glucose, total cholesterol, HDL cholesterol, LDL cholesterol, and triglycerides, as well as clinical characteristics, were evaluated before surgery and at 1, 3, 6, and 12 months after surgery. Results were compared between groups. Baseline characteristics were comparable in both groups. Mean operative time was significantly higher in the group of patients who underwent omentectomy (P < 0.001). Median weight of the omentum was 795 +/- 341 g. In one patient, a duodenal perforation occurred at the time of omentectomy. BMI, blood pressure, glucose, total cholesterol, LDL, and triglycerides significantly improved in both groups at 1, 3, 6, and 12 months of follow-up when compared with basal values. However, there were no consistent statistically significant differences among the groups in terms of metabolic syndrome components, acute-phase reactants, and inflammatory mediators. Omentectomy does not have an ancillary short-term significant impact on the components of metabolic syndrome and does not induce important changes in the inflammatory mediators in patients undergoing LRYGB. Operative time is more prolonged when omentectomy is performed.

Genitourinary tuberculosis still continues to plague developing countries and is a significant cause of morbidity as well as mortality in the developing world. At present, nearly 55% of the patients of genitourinary tuberculosis (GUTB) need surgical management. Owing to the presence of dense adhesions and loss of normal anatomical planes, GUTB was considered to be a contraindication to laparoscopic surgery. However, recent literature shows laparoscopy to be feasible in GUTB. Our study aimed at identifying the challenges in laparoscopic urinary tract reconstructive surgery in genitourinary tuberculosis-related urinary tract obstruction. The details of 6 patients who underwent different types of laparoscopic reconstructive surgery for genitourinary tuberculosis-related urinary tract obstruction from January 2014 to December 2015 were reviewed. Baseline characteristics, indications of surgery, type of surgery, operative duration, blood loss, and follow-up details were noted. All patients received antitubercular treatment before surgery as per the direct observed treatment short-course regimen followed in our country. We performed one bilateral laparoscopic pyeloplasty, one unilateral laparoscopic pyeloplasty, two laparoscopic ureteroneocystostomies, and two ureteroureterostomies. Difficulty was encountered during dissection owing to the presence of adhesions, but conversion to open surgery was not done in five cases. Dense adhesions adjacent to the common iliac vessels necessitated conversion to open surgery in one of the ureteroureterostomies. Stenting was done in all the patients. All patients had uneventful postoperative recovery. Functional imaging following stent removal showed unobstructed tracer flow, showing successful operative outcome. Our study showed that laparoscopic reconstructive surgery is feasible in genitourinary tuberculosis despite the presence of adhesions that may pose a challenge to dissection. This is in contrast to the previous studies which conclude that genitourinary tuberculosis is a relative contraindication to laparoscopic surgery.

Objective assessment of technique in laparoscopic colorectal surgery: what are the existing tools?

Assessment can improve the effectiveness of surgical training and enable valid judgments of competence. Laparoscopic colon resection surgery is now taught within surgical residency programs, and assessment tools are increasingly used to stimulate formative feedback and enhance learning. Formal assessment of technical performance in laparoscopic colon resection has been successfully applied at the specialist level in the English "LAPCO" National Training Program. Objective assessment tools need to be developed for training and assessment in laparoscopic rectal cancer resection surgery. Simulation may have a future role in assessment and accreditation in laparoscopic colorectal surgery; however, existing virtual reality models are not ready to be used for assessment of this advanced surgery.

This study examines patient and operative factors associated with organ space infection (OSI) in children after appendectomy, specifically focusing on the role of operative approach. Although controversy exists regarding the risk of increased postoperative intra-abdominal infections after laparoscopic appendectomy, this approach has been largely adopted in the treatment of pediatric acute appendicitis. Children aged 2 to 18 years undergoing open or laparoscopic appendectomy for acute appendicitis were selected from the 2012 American College of Surgeons Pediatric National Surgical Quality Improvement Program database. Univariate analysis compared patient and operative characteristics with 30-day OSI and incisional complication rates. Factors with a P value of less than 0.1 and clinical importance were included in the multivariable logistic regression models. A P value less than 0.05 was considered significant. For 5097 children undergoing appendectomy, 4514 surgical procedures (88.6%) were performed laparoscopically. OSI occurred in 155 children (3%), with half of these infections developing postdischarge. Significant predictors for OSI included complicated appendicitis, preoperative sepsis, wound class III/IV, and longer operative time. Although 5.2% of patients undergoing open surgery developed OSI (odds ratio = 1.82; 95% confidence interval, 1.21-2.76; P = 0.004), operative approach was not associated with increased relative odds of OSI (odds ratio = 0.99; confidence interval, 0.64-1.55; P = 0.970) after adjustment for other risk factors. Overall, the model had excellent predictive ability (c-statistic = 0.837). This model suggests that disease severity, not operative approach, as previously suggested, drives OSI development in children. Although 88% of appendectomies in this population were performed laparoscopically, these findings support utilization of the surgeon's preferred surgical technique and may help guide postoperative counsel in high-risk children.

Amino acid administration helps to prevent intraoperative hypothermia but may enhance thermogenesis when combined with glucose infusion. The aim of this study was to examine the effect of intraoperative amino acid administration, with or without glucose infusion, on temperature regulation during laparoscopic colectomy. Twenty-one patients whose physical status was classified I or II by the American Society of Anesthesiologists, and who were undergoing elective laparoscopic colectomy were enrolled. The exclusion criteria were a history of diabetes and/or obesity, preoperative high levels of C-reactive protein, high blood glucose and/or body temperature after anesthesia induction, and surgical time >500 minutes. Each patient received an acetate ringer solution and was randomly assigned to one of three groups. Group A patients were given only amino acids. Group AG patients were given amino acids and glucose. Group C patients were given neither amino acids nor glucose. Tympanic membrane temperatures and blood glucose and insulin levels were measured intraoperatively. Intraoperative amino acid infusion significantly increased body temperature during surgery as compared with either Group AG or C. The blood glucose levels in Group AG were significantly higher than those in Groups A and C. However, there were no significant differences between Groups A and C. Two hours after anesthesia induction, serum insulin levels in Groups A and AG significantly increased compared with Group C. No significant differences in the postoperative complications or patient hospitalization lengths were detected between the groups. Intraoperative amino acid infusion without glucose administration maintains body temperature more effectively than combined amino acid and glucose infusion in patients undergoing laparoscopic colectomy, despite unaltered intraoperative insulin levels.

Objective: We evaluated the outcomes of routine laparoscopy and laparoscopic appendectomy (LA) in patients with suspected appendicitis. This is a retrospective study of the outcomes of patients undergoing laparoscopic appendectomy compared with outcomes for patients undergoing open appendectomy (OA) during the time that LA came into use. Method: Results of patients managed with routine laparoscopy and LA for suspected acute appendicitis were reviewed and analyzed. The preoperative and intraoperative findings were recorded. The clinical outcomes were compared with those of patients undergoing OA in the preceding 10 months. Results: During the LA study period, 97 patients (47 men) with the median age of 34 years (range, 18 to 79) presented with clinical features of acute appendicitis. With the exclusion of 5 patients with open operations and 10 patients with other pathologies, 82 patients underwent laparoscopic appendectomy (Group A) for appendicitis. Thirty-one (37.8%) patients had complicated appendicitis (perforated or gangrenous appendicitis). Conversions were required in 6 patients (7.3%). During the OA period, 125 patients (57 men) with the median age of 42 (range, 19 to 79) years were operated on. With the exclusion of 6 patients with other pathologies, 119 underwent OA for acute appendicitis (Group B). Fifty-one (42.9%) had either perforated or gangrenous appendicitis. The median durations of surgery in Group A and Group B were 80 minutes (range, 40 to 195) and 60 minutes (range, 25 to 260), respectively (P<0.005). Postoperative complication rates were comparable between the 2 groups (13.4% in Group A versus 15.8% in Group B). The median hospital stay for patients in Group A and Group B were 3.0 days (range, 1 to 47) and 4.0 days (range, 1 to 47), respectively (P=0.037). Conclusions: We conclude that routine laparoscopy and LA for suspected acute appendicitis is safe and is associated with a significantly shorter hospital stay. Other intra-abdominal pathologies can also be diagnosed more accurately with the laparoscopic approach. PMID:16882418

Abstract The development of new medical electronic devices and equipment has increased the use of electrical apparatuses in surgery. Many studies have reported the association of long-term exposure to extremely low-frequency magnetic fields (ELF-MFs) with diseases or cancer. Robotic surgery has emerged as an alternative tool to overcome the disadvantages of conventional laparoscopic surgery. However, there has been no report regarding how much ELF-MF surgeons are exposed to during laparoscopic and robotic surgeries. In this observational study, we aimed to measure and compare the ELF-MFs that surgeons are exposed to during laparoscopic and robotic surgery. The intensities of the ELF-MFs surgeons are exposed to were measured every 4 seconds for 20 cases of laparoscopic surgery and 20 cases of robotic surgery using portable ELF-MF measuring devices with logging capability. The mean ELF-MF exposures were 0.6 ± 0.1 mG for laparoscopic surgeries and 0.3 ± 0.0 mG for robotic surgeries (significantly lower with P < 0.001 by Mann–Whitney U test). Our results show that the ELF-MF exposure levels of surgeons in both robotic and conventional laparoscopic surgery were lower than 2 mG, which is the most stringent level considered safe in many studies. However, we should not overlook the effects of long-term ELF-MF exposure during many surgeries in the course of a surgeon's career. PMID:25674758

The laparoscopic technique was introduced in gastrointestinal surgery in the mid 1980s. Since then, the development of this technique has been extraordinary. Triggered by technical innovations (stapling devices or coagulation/dissecting devices), nowadays any type of gastrointestinal resection has been successfully performed laparoscopically and can be performed laparoscopically dependent on the patient's condition. This summary gives an overview over 30 years of laparoscopic surgery with focus on today's indications and evidence. Main indications remain the more common procedures, e.g., appendectomy, cholecystectomy, bariatric procedures or colorectal resections. For all these indications, the laparoscopic approach has become the gold standard with less perioperative morbidity. Regarding oncological outcome there have been several high-quality randomized controlled trials which demonstrated equivalency between laparoscopic and open colorectal resections. Less common procedures like esophagectomy, oncological gastrectomy, liver and pancreatic resections can be performed successfully as well by an experienced surgeon. However, the evidence for these special indications is poor and a general recommendation cannot be given. In conclusion, laparoscopic surgery has revolutionized the field of gastrointestinal surgery by reducing perioperative morbidity without disregarding surgical principles especially in oncological surgery.

Different surgical procedures impose different physical demands on surgeons and high prevalence rates of neck and shoulder pain have been reported among general surgeons. Past research has examined electromyography in surgeons mainly during simulated conditions of laparoscopic and open surgery but not during real-time operations and not for long durations. The present study compares the neck-shoulder muscle activities in three types of surgery and between different surgeons. The relationships of postural muscle activities to musculoskeletal symptoms and personal factors also are examined. Twenty-five surgeons participated in the study (23 men). Surface electromyography (EMG) was recorded in the bilateral cervical erector spinae, upper trapezius, and anterior deltoid muscles during three types of surgical procedures: open, laparoscopic, and endovascular. In each procedure, EMG data were captured for 30 min to more than 1 h. The surgeons were asked to rate any musculoskeletal symptoms before and after surgery. The present study showed significantly higher muscle activities in the cervical erector spinae and upper trapezius muscles in open surgery compared with endovascular and laparoscopic procedures. Muscle activities were fairly similar between endovascular and laparoscopic surgery. The upper trapezius usually has an important role in stabilizing both the neck and upper limb posture, and this muscle also recorded higher activities in open compared with laparoscopic and endovascular surgeries. Surgeons reported similar degrees of musculoskeletal symptoms in open and laparoscopic surgeries, which were higher than endovascular surgery. The present study showed that open surgery imposed significantly greater physical demands on the neck muscles compared with endovascular and laparoscopic surgeries. This may be due to the lighter manual task demands of these minimally invasive surgeries compared with open procedures, which generally required more dynamic movements and more forceful exertions.

This study describes and evaluates a novel, robot-assisted laparoscopic ultrasonographic device for hepatic surgery. Laparoscopic liver surgery is being performed with increasing frequency. One major drawback of this approach is the limited capability of intraoperative ultrasonography (IOUS) using standard laparoscopic devices. Robotic surgery systems offer the opportunity to develop new tools to improve techniques in minimally invasive surgery. This study evaluates a new integrated ultrasonography (US) device with the da Vinci Surgical System for laparoscopic visualization, comparing it with conventional handheld laparoscopic IOUS for performing key tasks in hepatic surgery. A prototype laparoscopic IOUS instrument was developed for the da Vinci Surgical System and compared with a conventional laparoscopic US device in simulation tasks: (1) In vivo porcine hepatic visualization and probe manipulation, (2) lesion detection accuracy, and (3) biopsy precision. Usability was queried by poststudy questionnaire. The robotic US proved better than conventional laparoscopic US in liver surface exploration (85% success vs 73%; P = .030) and tool manipulation (79% vs 57%; P = .028), whereas no difference was detected in lesion identification (63 vs 58; P = .41) and needle biopsy tasks (57 vs 48; P = .11). Subjects found the robotic US to facilitate better probe positioning (80%), decrease fatigue (90%), and be more useful overall (90%) on the post-task questionnaire. We found this robot-assisted IOUS system to be practical and useful in the performance of important tasks required for hepatic surgery, outperforming free-hand laparoscopic IOUS for certain tasks, and was more subjectively usable to the surgeon. Systems such as this may expand the use of robotic surgery for complex operative procedures requiring IOUS. Copyright © 2012 Mosby, Inc. All rights reserved.

Crohn's disease is an inflammatory bowel disease which may affect different parts of the gastrointestinal tract. To compare retrospectively the results of laparotomy and laparoscopic surgery performed in patients with Crohn's disease between January 1, 2005 and October 31, 2012 in the Department of Surgery, University of Szeged, Hungary. Patients were divided into two groups based on the types of surgery; 103 patients underwent laparotomy and 30 patients had laparoscopic surgery programmed. 22 patients had 24 primary acute interventions. The mean age was significantly lower in the laparoscopic surgery group (p = 0.042). The laparoscopic ileocecal resections have been found significantly shorter than laparotomies (p = 0.033). When ileocecal resection was performed the operation time was significantly longer (p = 0.033) while hospitalization time (p = 0.025) and intensive care unit treatment time (p<0.001) were shorter and the bowel passage also started earlier in the laparoscopic group as compared to the laparotomy group. Laparoscopic surgery results in smaller surgical trauma, better cosmetic outcome, shorter hospitalization time and not higher complication- and morbidity-rate as well as shorter operation time in certain cases. However, it requires more qualified surgical team and the operation expenses are higher.

Robotic-assisted surgery has become increasingly common; however, it is unclear if its use for colectomy improves in-hospital outcomes compared with the laparoscopic approach. The aim of the study is to compare in-hospital outcomes and costs between patients undergoing robotic or laparoscopic colectomy. This study is a retrospective review of the 2008 to 2009 Nationwide Inpatient Sample. SETTINGS, PATIENTS, INTERVENTIONS: All adult patients who underwent an elective robotic or laparoscopic colectomy in hospitals performing both procedures (N = 2583 representing an estimated 12,732 procedures) were included. Outcomes included intraoperative and postoperative complications, length of stay, and direct costs of care. Regression models were used to compare these outcomes between procedural approaches while controlling for baseline differences in patient characteristics. Overall, 6.1% of patients underwent a robotic procedure. Factors associated with robotic-assisted colectomy included younger age, benign diagnoses, and treatment at a lower-volume center. Patients undergoing robotic and laparoscopic procedures experienced similar rates of intraoperative (3.0% vs 3.3%; adjusted OR = 0.88 (0.35-2.22)) and postoperative (21.7% vs 21.6%; adjusted OR = 0.84 (0.54-1.30)) complications, as well as risk-adjusted average lengths of stay (5.4 vs 5.5 days, p = 0.66). However, robotic-assisted colectomy resulted in significantly higher costs of care ($19,231 vs $15,807, p < 0.001). Although the overall postoperative morbidity rate was similar between groups, the individual complications experienced by each group were different. A limitation of this study is the potential miscoding of robotic cases in administrative data. Robotic-assisted colectomy significantly increases the costs of care without providing clear reductions in overall morbidity or length of stay. As the use of robotic technology in colon surgery continues to evolve, critical appraisal of the benefits offered in comparison with the resources consumed is required.

Laparoscopic Suturing as a Barrier to Broader Adoption of Laparoscopic Surgery.

Laparoscopic surgery is increasingly replacing the open procedure because of its many patient-related benefits that are well aligned with policies and programs that seek to optimize health system performance. However, widespread adoption of laparoscopic surgery has been slow, in part, because of the complexity of laparoscopic suturing. The objective of this study was to review the clinical and economic impacts of laparoscopic suturing in key procedures and to assess its role as a barrier to the broader adoption of laparoscopic surgery. A medical literature search of MEDLINE, EMBASE, and BIOSIS from January 2010 through June 2016 identified 47 relevant articles. Laparoscopic suturing and intracorporeal knot tying may result in extended surgical time, complications, and surgeon errors, while improving patient quality of life through improved cosmesis, diet toleration, and better bowel movements. Despite advancement in surgical techniques and the availability of newer surgical tools, the complexity of laparoscopic suturing continues to be a barrier to greater adoption of MIS. The results of the study underscore the need for development of proficiency in laparoscopic suturing, which may help improve patient outcomes and reduce healthcare costs.

Circular stapler and hand-sutured esophagojejunostomy has been the most popular technique utilized in patients undergoing proximal gastrectomy through Roux-en-Y reconstruction for disease processes of the gastroesophageal junction. In recent years, with the advent of laparoscopic bariatric surgical techniques and refined linear stapler cutters, surgeons have developed the linear stapler side-to-side technique as a valid option. The aim of this study is to describe our technique and review the outcomes using the Roux-en-Y reconstruction with linear staplers after laparoscopic proximal gastrectomy for malignant and benign disease. After Internal Review Board approval and with adherence to the Health Insurance Portability and Accountability Act guidelines, a retrospective review of a prospectively collected database was conducted. A total of 14 patients underwent proximal laparoscopic gastric resection at our institution during a 3-year period from January 2008 to January 2011. Sex, body mass index, prior surgeries, complications of the prior surgery, intraoperative complications, pathologic findings, postoperative complications, hospital stay, and outpatient follow-up were measured in the preoperative and postoperative period. Our patient population consisted of 9 women and 5 men, with a mean age and body mass index of 45.42 years and 35.64 kg/m, respectively. Indications for proximal gastrectomy was in 4 patients a leak at the angle of His secondary to sleeve gastrectomy for morbid obesity, 1 patient was a stricture after a vertical banded gastroplasty, 1 patient a revision of a eroded gastric band, 1 patient a revision of a eroded mesh secondary to a hiatal hernia repair, 1 patient a conversion of a failed Nissen, 3 patients had a total gastrectomy due to a stage 2 gastric cancer, and 1 patient a gastrointestinal stromal tumor. There were no intraoperative complications. All the procedures were completed laparoscopically. The mean operative time was 137.16 minutes. The mean hospital stay was 7.6 days. One patient had a postoperative stricture at the esophagojejunal anastomosis that required multiple dilatations. All patients with gastric cancer are free of tumor recurrence. The use of a laparoscopic proximal gastrectomy with Roux-en-Y reconstruction through combined side-to-side linear stapler and hand-sewn esophagojejunal anastomosis seems to be a feasible and safe approach.

Intraoperative hypothermia during both open and laparoscopic abdominal surgery may be associated with adverse events. For laparoscopic abdominal surgery, the use of heated insufflation systems for establishing pneumoperitoneum has been described to prevent hypothermia. Humidification of the insufflated gas is also possible. Past studies have shown inconclusive results with regards to maintenance of core temperature and reduction of postoperative pain and recovery times. To determine the effect of heated gas insufflation on patient outcomes following minimally invasive abdominal surgery. The Cochrane Central Register of Controlled Trials (CENTRAL) (The Cochrane Library), MEDLINE (PubMed), EMBASE, International Pharmaceutical Abstracts (IPA), Web of Science, Scopus, www.clinicaltrials.gov and the National Research Register were searched (1956 to 14 June 2010). Grey literature and cross-references were also searched. Searches were limited to human studies without language restriction. All included studies were randomized trials comparing heated (with or without humidification) gas insufflation with cold gas insufflation in adult and pediatric populations undergoing minimally invasive abdominal procedures. Study quality was assessed in regards to relevance, design, sequence generation, allocation concealment, blinding, possibility of incomplete data and selective reporting. The selection of studies for the review was done independently by two authors, with any disagreement resolved in consensus with a third co-author. Screening of eligible studies, data extraction and methodological quality assessment of the trials were performed by the authors. Data from eligible studies were collected using data sheets. Results were presented using mean differences for continuous outcomes and relative risks with 95% confidence intervals for dichotomous outcomes. The estimated effects were calculated using the latest version of RevMan software. Publication bias was taken into consideration and funnel plots were compiled. Sixteen studies were included in the analysis. During laparoscopic abdominal surgery, no effect on postoperative pain nor changes in core temperature, morphine consumption, length of hospitalisation, lens fogging, length of operation or recovery room stay were associated with heated compared to cold gas insufflation with or without humidification. The study offers evidence that during laparoscopic abdominal surgery, heated gas insufflation, with or without humidification, has minimal benefit on patient outcomes.

Laparoscopy was the most significant technologic advance in colorectal surgery in the last quarter century. The safety, feasibility and oncologic equivalence have been proven, and undisputed clinical benefits have also been demonstrated over open approaches. Despite proven benefits, laparoscopic has not dominated the market, especially for colon and rectal cancer cases. Adaptations in laparoscopic technique were developed to increase use of minimally invasive surgery. Concurrently, there has been a paradigm shift toward less invasive technologies to further optimize patient outcomes. From these needs, hand assisted laparoscopic surgery (HALS), single incision laparoscopic surgery (SILS), and robotic assisted laparoscopic surgery (RALS) were applied to colorectal surgery. Each platform has unique costs and benefits, and similar outcomes when likened to each other in comparative studies. However, conventional laparoscopy, HALS, SILS, and RALS actually serve a complementary role as tools to increase the use of minimally invasive colorectal surgery. The goal of this paper is to review the history, current status, technical specifications, and evolution of the major minimally invasive platforms for colorectal surgery.

Appendicitis is the most common gastrointestinal pediatric surgical emergency. With the introduction of laparoscopic techniques in the 1990s, recovery, pain, and hospital stay after laparoscopic procedures have been significantly reduced. While many laparoscopic procedures are performed as outpatient surgeries, pediatric appendectomy patients continue to be hospitalized for postoperative observation. Our goal was to evaluate the safety and feasibility of same day discharge after laparoscopic appendectomy for uncomplicated appendicitis. After IRB approval, all pediatric patients undergoing laparoscopic appendectomy during 2016 for noncomplicated appendicitis were eligible for the study. Decision for same day discharge was based on surgeon preference and parental agreement. Data regarding demographics, admission and discharge times, outcomes of complications, readmissions, return to the ED, and nonscheduled clinic visits were collected. A total of 1321 appendectomies were performed during the study period, of which 849 were uncomplicated and 382 were discharged same day. There were 2 readmissions, 4 superficial surgical site infections, 10 patients with nausea or vomiting, and 33 patients with pain control issues, 9 of whom presented to the ED. Same day discharge for laparoscopic noncomplicated appendectomy is a safe and feasible alternative to postoperative admission and observation. This has the potential to yield significant healthcare cost savings. Level II, Prospective Cohort Study. Copyright © 2018. Published by Elsevier Inc.

Background The aim of this study was to define any benefits in terms of early outcome for laparoscopic colectomy in patients over 75 years old (OP) compared with the outcomes of a younger populations (YP). Methods Forty elderly patients undergoing laparoscopic colectomy for colorectal cancer between 2007-2011 were studied, the patients are divided for gender, age, year of surgery, site of cancer, and comorbidity on admission and compared with 40 younger patients. Results and discussion Mean (standard deviation) age was 81.3 in OP and 68.3 YP Conversion rate was the same between the two groups. There was no difference in operative mean time . The overall mortality rate was 0% percent. The surgical morbidity rate was the same but there was an increased in cardiologic e bronchopneumonia complications in older population. Patients treated with laparoscopic approach had a faster recovery of bowel function and a significant reduction of the mean length of hospital stay not age related. Laparoscopy allowed a better preservation of postoperative independence status. Conclusions Laparoscopic colectomy for cancer in elderly patients is safe and beneficial including preservation of postoperative independence and a reduction of length of hospital stay.

Background: Postoperative nausea and vomiting (PONV) is commonly seen after laparoscopic surgery. In this randomized double blind prospective clinical study, we investigated and compared the efficacy of palonosetron and granisetron to prevent postoperative nausea and vomiting after laparoscopic cholecystectomy. Patients & Methods: Sixty female patients (18-65 yrs of age) undergoing elective laparoscopic cholecystectomy were randomly allocated one of the two groups containing 30 patients each. Group P received palonosetron 75 μg intravenously as a bolus before induction of anaesthesia. Group G received granisetron 2.5 mg intravenously as a bolus before induction. Results: The incidence of a complete response (no PONV, no rescue medication) during 0-3 hour in the postoperative period was 86.6% with granisetron and 90% with palonosetron, the incidence during 3-24 hour postoperatively was 83.3% with granisetron and 90% with palonosetron. During 24-48 hour, the incidence was 66.6% and 90% respectively (p<0.05). The incidence of adverse effects were statistically insignificant between the groups. Conclusion: Prophylactic therapy with palonosetron is more effective than granisetron for long term prevention of postoperative nausea and vomiting after laparoscopic cholecystectomy. PMID:21547174

The laparoscopic surgery for gastrointestinal cancer developed slowly and was at a crossroad of choice at the beginning of the 21st century. However, the team of laparoscopic surgery in Nanfang Hospital was keenly conscious that minimally invasive surgery (MIS) would bring new era to the treatment of gastrointestinal cancer. Therefore, our team went into the exploration of laparoscopic surgery for gastrointestinal cancer: (1) researching a series of anatomical theories for MIS; (2) lucubrating the applicable pattern of fascia and mesentery under laparoscopic view; (3) finding out the precise anatomical landmarks and surgical layers; (4) optimizing the operative strategy. Fortunately, we proposed a safe and simplified strategy of laparoscopic gastrointestinal cancer surgery for Chinese patients with locally advanced stage. Gradually, this strategy was widely adopted by most colleagues in this field. Meanwhile, our team realized the necessity and urgency of education and training for primary care physicians, thus we designed courses based on different laparoscopic levels of the trainees. Also we actively developed the teaching model suitable for the presentation of visual surgery, by taking advantages of mobile network and glasses-free 3D, to break through the limit of time and space in teaching and learning. Besides, we used the internet to create an education system of real-time, opening, practical and efficient academic communication platform, so that more surgeons across the country would be able to synchronize and interact with the experts more instantly and efficiently. All the way, our team hammered at optimizing laparoscopic surgery procedures, along with further perfecting and standardizing training and education system. This article intends to review, summarize and share our experiences in laparoscopic training and education for gastrointestinal surgery, also to remind ourselves of staying true and carry on in this field.

To assess patterns of uptake and outcomes of laparoscopic colon and rectal cancer surgery in Ontario, and the potential influence of surgical fee incentives instituted on October 1, 2005. We used Ontario administrative databases from fiscal years 2002 to 2009. Study outcomes were uptake rates of laparoscopic surgery, hospital length of stay, 30-day operative mortality, cancer-specific survival, and overall survival. The main descriptor for multivariable regression models was a 5% increase in rate of laparoscopic colon cancer surgery in the previous year. The annual rate of laparoscopic colon and rectal cancer surgery, respectively, rose from 8.7 to 38.9% and from 4.8 to 19.6%. The greatest increase in rate of laparoscopic colon surgery occurred shortly after October 1, 2005. For each 5% increase in rate of laparoscopic surgery, the odds of 30-day mortality was 1.0 [95% confidence interval (CI) 0.96-1.01, p = 0.264], the hazard of cancer-specific survival was 1.0 (95% CI 0.97-1.00, p = 0.139), the hazard of overall survival was 1.0 (95% CI 0.98-1.00, p = 0.051), and length of hospital stay was lower (estimate = -0.10, 95% CI -0.14 to -0.06, p < 0.001). In Ontario by the year 2009, 39% of colon and 20% of rectal cancer surgery was provided laparoscopically. Increased rates were associated with a minimal decrease in hospital length of stay and no changes in 30-day mortality, cancer-specific survival, or overall survival. Financial incentives were likely responsible for the marked increase in laparoscopic colon cancer surgery observed after October 1, 2005.

Laparoscopic sleeve gastrectomy is a safe and effective bariatric operation, but postoperative reflux symptoms can sometimes necessitate revisional surgery. Roux-en-Y gastric bypass is the preferred operation in morbidly obese patients with gastro-oesophageal reflux disease. In 2011, we introduced preoperative endoscopy to assess for hiatus hernia or evidence of oesophagitis in conjunction with an assessment of gastro-oesophageal reflux symptoms for all patients undergoing bariatric surgery with a view to avoid sleeve gastrectomy for these patients. A prospectively maintained database was used to identify patients who underwent sleeve gastrectomy before and after we changed the unit policy. The need for revisional surgery in patients with troublesome gastro-oesophageal reflux disease was examined. Prior to 2011, 130 patients underwent sleeve gastrectomy, and 11 (8.5%) of them required conversion to Roux-en-Y gastric bypass for symptomatic reflux disease. Following the policy change, 284 patients underwent sleeve gastrectomy, and to date, only five (1.8%) have required revisional surgery (p = 0.001). Baseline demographics were comparable between the groups, and average follow-up period was 47 and 33 months, respectively, for each group. Preoperative endoscopy and a detailed clinical history regarding gastro-oesophageal reflux symptoms may improve patient selection for sleeve gastrectomy. Avoiding sleeve gastrectomy in patients with reflux disease and/or hiatus hernia may reduce the incidence of revisional surgery. © 2016 World Obesity.

Bariatric surgery is a well-documented treatment for obesity, but there are uncertainties about the degree to which such surgery is associated with health care cost reductions that are sustained over time. To provide a comprehensive, multiyear analysis of health care costs by type of procedure within a large cohort of privately insured persons who underwent bariatric surgery compared with a matched nonsurgical cohort. Longitudinal analysis of 2002-2008 claims data comparing a bariatric surgery cohort with a matched nonsurgical cohort. Seven BlueCross BlueShield health insurance plans with a total enrollment of more than 18 million persons. A total of 29 820 plan members who underwent bariatric surgery between January 1, 2002, and December 31, 2008, and a 1:1 matched comparison group of persons not undergoing surgery but with diagnoses closely associated with obesity. Standardized costs (overall and by type of care) and adjusted ratios of the surgical group's costs relative to those of the comparison group. Total costs were greater in the bariatric surgery group during the second and third years following surgery but were similar in the later years. However, the bariatric group's prescription and office visit costs were lower and their inpatient costs were higher. Those undergoing laparoscopic surgery had lower costs in the first few years after surgery, but these differences did not persist. Bariatric surgery does not reduce overall health care costs in the long term. Also, there is no evidence that any one type of surgery is more likely to reduce long-term health care costs. To assess the value of bariatric surgery, future studies should focus on the potential benefit of improved health and well-being of persons undergoing the procedure rather than on cost savings.

Laparoscopic colorectal surgery has now become widely adopted for the treatment of colorectal neoplasia, with steady increases in utilization over the past 15 years. Common minimally invasive techniques include multiport laparoscopy, single-incision laparoscopy, and hand-assisted laparoscopy, with the choice of technique depending on several patient and surgeon factors. Laparoscopic colorectal surgery involves a robust learning curve, and fellowship training often lays the foundation for a high-volume laparoscopic practice. This article provides a summary of the various techniques for laparoscopic colorectal surgery, including operative steps, the approach to difficult patients, and the learning curve for proficiency.

Previous studies have shown that laparoscopic colorectal cancer surgery is highly safe and effective compared to laparotomy. However, whether laparoscopic colorectal cancer surgery can be safely performed in patients with severe comorbidities remains unclear. The aim of this study was to evaluate the safety of laparoscopic colorectal cancer surgery in patients with severe comorbidities. A total of 82 consecutive patients with colorectal cancer who underwent laparoscopic surgery were retrospectively divided into two groups according to whether they had severe comorbidity (50 patients) or non-severe comorbidity (32 patients). An age-adjusted Charlson comorbidity index of ≥6 was defined as severe comorbidity. Operative time, blood loss, and rate of conversion to laparotomy did not differ between the groups. Postoperative complications and the length of the postoperative hospital stay also did not differ significantly between the groups. Laparoscopic colorectal cancer surgery is feasible and safe, even in patients with severe comorbidities. Copyright© 2018, International Institute of Anticancer Research (Dr. George J.

To determine direct-acting oral anticoagulant (DOAC) blood levels in post-bariatric surgery (BS) patients treated with long-term anticoagulation therapy. We identified from medical records patients who underwent BS during 2005-2016 and who were treated with DOACs. We offered testing DOAC blood levels to these patients and to age, sex, body mass index, and serum creatinine-matched individuals treated by DOACs who did not undergo BS. Overall, 36 individuals were enrolled, 18 post-BS patients and 18 control subjects. Of the post-BS patients, 12 underwent laparoscopic sleeve gastrectomy, 4 laparoscopic adjustable gastric banding and 2 laparoscopic Roux-en-Y gastric bypass surgery. Median time lapsed from surgery until study inclusion was 4.9years. Five post-BS patients had peak drug levels below expected levels compared to none of the control subjects (P=0.05). For patients who used apixaban (n=9) and dabigatran (n=2), peak drug levels were within the expected range. In contrast, for the 7 patients who used rivaroxaban, levels were below the expected range in 5, including all four who underwent sleeve gastrectomy and one following adjustable gastric banding. Peak rivaroxaban levels were significantly lower in the post-BS than the control group (P=0.02). This preliminary study suggests that all DOACs, particularly rivaroxaban, be cautiously used following BS, if used at all. Given that vitamin-K antagonists can be easily monitored, they may be a better choice, until more data on DOAC use in this patient population are available. Copyright © 2017 Elsevier Ltd.

No randomized trial exists that specifically addresses the issue of laparoscopic bilateral inguinal hernia repair. The purpose of the present prospective, randomized, controlled, clinical study was to assess short- and long-term results when comparing simultaneous bilateral hernia repair by an open, tension-free anterior approach with laparoscopic "bikini mesh" posterior repair. Forty-three low-risk male patients with bilateral primary inguinal hernia were randomly assigned to undergo either laparoscopic preperitoneal "bikini mesh" hernia repair (TAPP) or open Lichtenstein hernioplasty. There was no difference in operating time between the two groups. The mean cost of laparoscopic hernioplasty was higher (P < 0.001). The intensity of postoperative pain was greater in the open hernia repair group at 24 hours, 48 hours, and 7 days after surgery (P < 0.001), with a greater consumption of pain medication among these patients (P < 0.05). The median time to return to work was 30 days for the open hernia repair group and 16 days for the laparoscopic "bikini mesh" repair group (P < 0.05). Only 1 asymptomatic recurrence (4.3%) was discovered in the open group. The laparoscopic approach to bilateral hernia with "bikini mesh" appears to be preferable to the open Lichtenstein tension-free hernioplasty in terms of the postoperative quality of life and interruption of occupational activity.

Transversus abdominis plane (TAP) block has been used to provide intra- and post-operative analgesia with single incision laparoscopic (SIL) bariatric and gynecological surgery with mixed results. Its efficacy in providing analgesia for SIL cholecystectomy (SILC) via the same approach remains unexplored. The primary objective of our study was to compare the efficacy of bilateral TAP block with local anesthetic infiltration for perioperative analgesia in patients undergoing SILC. This was a prospective, randomized, controlled, double-blinded trial performed in a tertiary care hospital. Forty-two patients undergoing SILC were randomized to receive either ultrasound-guided (USG) bilateral mid-axillary TAP blocks with 0.375% ropivacaine or local anesthetic infiltration of the port site. The primary outcome measure was the requirement of morphine in the first 24 h postoperatively. The data were analyzed using t -test, Mann-Whitney test or Chi-square test. The 24 h morphine requirement (mean ± standard deviation) was 34.57 ± 14.64 mg in TAP group and 32.76 ± 14.34 mg in local infiltration group ( P = 0.688). The number of patients requiring intraoperative supplemental fentanyl in TAP group was 8 and in local infiltration group was 16 ( P = 0.028). The visual analog scale scores at rest and on coughing were significantly higher in the local infiltration group in the immediate postoperative period ( P = 0.034 and P = 0.007, respectively). USG bilateral TAP blocks were not effective in decreasing 24 h morphine requirement as compared to local anesthetic infiltration in patients undergoing SILC although it provided some analgesic benefit intraoperatively and in the initial 4 h postoperatively. Hence, the benefits of TAP blocks are not worth the effort and time spent for administering them for this surgery.

Here, we report two patients with transomental hernia who were successfully treated with laparoscopic surgery. The first patient was a 58-year-old female who presented to our hospital with abdominal pain and vomiting; she had no history of abdominal surgery. Enhanced computed tomography revealed strangulation ileus due to an internal hernia. The second patient was a 36-year-old male who presented to our hospital with abdominal pain and no history of abdominal surgery. Enhanced computed tomography indicated transomental hernia. Emergency laparoscopic surgery in both patients revealed incarcerated bowel loops through defects in the greater omentum. The bowel segments were laparoscopically released, and the patients were uneventfully discharged on postoperative Days 4 and 8. Laparoscopic surgery is useful for the diagnosis and treatment of small bowel obstruction due to transomental hernia through the greater omentum.

Ultravision™ is a new device that utilizes electrostatic precipitation to clear surgical smoke. The aim was to evaluate its performance during laparoscopic cholecystectomy. Patients undergoing laparoscopic cholecystectomy were randomized into "active (device on)" or "control (device off)." Three operating surgeons scored the percentage effective visibility and three reviewers scored the percentage of the procedure where smoke was present. All assessors also used a 5-point scale (1 = imperceptible/excellent and 5 = very annoying/bad) to rate visual impairment. Secondary outcomes were the number of smoke-related pauses, camera cleaning, and pneumoperitoneum reductions. Mean results are presented with 95% confidence intervals (CI). In 30 patients (active 13, control 17), the effective visibility was 89.2% (83.3-95.0) for active cases and 71.2% (65.7-76.7) for controls. The proportion of the procedure where smoke was present was 41.1% (33.8-48.3) for active cases and 61.5% (49.0-74.1) for controls. Operating surgeons rated the visual impairment as 2.2 (1.7-2.6) for active cases and 3.2 (2.8-3.5) for controls. Reviewers rated the visual impairment as 2.3 (2.0-2.5) for active cases and 3.2 (2.8-3.7) for controls. In the active group, 23% of procedures were paused to allow smoke clearance compared to 94% of control cases. Camera cleaning was not needed in 85% of active procedures and 35% of controls. The pneumoperitoneum was reduced in 0% of active cases and 88% of controls. Ultravision™ improves visibility during laparoscopic surgery and reduces delays in surgery for smoke clearance and camera cleaning.

Objective To compare peri- and post-operative complications and outcomes of robotic-assisted surgical staging with traditional laparoscopic surgical staging for women with endometrial cancer. Methods A retrospective chart review of cases of women undergoing minimally invasive total hysterectomy and pelvic and para-aortic lymphadenectomy by a robotic-assisted approach or traditional laparoscopic approach was conducted. Major intraoperative complications, including vascular injury, enterotomy, cystotomy, or conversion to laparotomy, were measured. Secondary outcomes including operative time, blood loss, transfusion rate, number of lymph nodes retrieved, and the length of hospitalization were also measured. Results 275 cases were identified–102 patients with robotic-assisted staging and 173 patients with traditional laparoscopic staging. There was no significant difference in the rate of major complications between groups (p=0.13). The mean operative time was longer in cases of robotic-assisted staging (237 min vs. 178 min, p<0.0001); however, blood loss was significantly lower (109 ml vs. 187 ml, p<0.0001). The mean number of lymph nodes retrieved were similar between groups (p=0.32). There were no significant differences in the time to discharge, re-admission, or re-operation rates between the two groups. Conclusion Robotic-assisted surgery is an acceptable alternative to laparoscopy for minimally invasive staging of endometrial cancer. In addition to the improved ease of operation, visualization, and range of motion of the robotic instruments, robotic surgery results in a lower mean blood loss, although longer operative time. More data are needed to determine if the rates of urinary tract injuries and other surgical complications can be reduced with the use of robotic surgery. PMID:20144471

Background The purpose of the study was to determine the outcome of all patients with endometrial adenocarcinoma cancer treated by laparoscopic hysterectomy at our institution, many of whom were high-risk for surgery. Methods Data was collected by a retrospective search of the case notes and Electronic Patient Records of the thirty eight patients who underwent laparoscopic hysterectomy for endometrial cancer at our institutions. Results The median body mass index was 30 (range 19–67). Comorbidities were present in 76% (29 patients); 40% (15 patients) had a single comorbid condition, whilst 18% (7 patients) had two, and a further 18% (7 patients) had more than two. Lymphadenectomy was performed in 45% (17 patients), and lymph node sampling in 21% (8 patients). Median operating time was 210 minutes (range 70–360 minutes). Median estimated blood loss was 200 ml (range 50–1000 ml). There were no intraoperative complications. Post-operative complications were seen in 21% (2 major, 6 minor). Blood transfusion was required in 5% (2 patients). The median stay was 4 post-operative nights (range 1–25 nights). In those patients undergoing lymphadenectomy, the mean number of nodes taken was fifteen (range 8–26 nodes). The pathological staging was FIGO stage I 76% (29 patients), stage II 8% (3 patients), stage III 16% (6 patients). The pathological grade was G1 31% (16 patients), G2 45% (17 patients), G3 24% (8 patients). Conclusion Laparoscopic hysterectomy can be safely carried out in patients at high risk for surgery, with no compromise in terms of outcomes, whilst providing all the benefits inherent in minimal access surgery.

After laparoscopic cholecystectomy, patients have moderate pain in the early postoperative period. Some studies shown beneficial effects of subcostal transversus abdominis plane block on reducing this pain. Our goal was to investigate influence of subcostal transversus abdominis plane block on postoperative pain scores and opioid consumption. We have randomized 76 patients undergoing laparoscopic cholecystectomy to receive either subcostal transversus abdominis plane block (n=38) or standard postoperative analgesia (n=38). First group received bilateral ultrasound guided subcostal transversus abdominis plane block with 20mL of 0.33% bupivacaine per side before operation and tramadol 1mg.kg -1 IV for pain breakthrough (≥6). Second group received after operation tramadol 1mg.kg -1 /6h as standard hospital analgesia protocol. Both groups received acetaminophen 1g/8h IV and metamizole 2.5g/12h. Pain at rest was recorded for each patient using NR scale (0-10) in period of 10min, 30min, 2h, 4h, 8h, 12h and 16h after the surgery. We obtained no difference between groups according age, weight, intraoperative fentanyl consumption and duration of surgery. Subcostal transversus abdominis plane block significantly reduced postoperative pain scores compared to standard analgesia in all periods after surgery. Tramadol consumption was significantly lower in the subcostal transversus abdominis plane (24.29±47.54g) than in the standard analgesia group (270.2±81.9g) (p=0.000). Our results show that subcostal transversus abdominis plane block can provide superior postoperative analgesia and reduction in opioid requirements after laparoscopic cholecystectomy.

We report a prospective, randomized comparison of transperitoneal laparoscopic adrenalectomy (TLA) vs retroperitoneal laparoscopic adrenalectomy (RLA) for adrenal lesions with long-term followup. Between December 1997 and November 1999, 57 consecutive eligible patients with surgical adrenal disease were prospectively randomized to undergo TLA (25) or RLA (32). Study exclusion criteria were patient age greater than 80 years, body mass index greater than 40, bilateral adrenalectomy and significant prior abdominal surgery in the quadrant of interest. Mean followup was 5.96 years in the 2 groups. The groups were matched in regard to patient age (p = 0.84), body mass index (p = 0.43), American Society of Anesthesiologists class (p = 0.81) and laterality (p = 0.12). Median adrenal mass size was 2.7 cm (range 1 to 9) in the TLA group and 2.6 cm (range 0.5 to 6) in the RLA group (p = 0.83). TLA was comparable to RLA in terms of operative time (130 vs 126.5 minutes, p = 0.64), estimated blood loss (p = 0.92), specimen weight (p = 0.81), analgesic requirements (p = 0.25), hospital stay (p = 0.56) and the complication rate (p = 0.58). One case per group was electively converted to open surgery. Pathology data on the intact extracted specimens were similar between the groups. Averaged convalescence was 4.7 weeks in the TLA group and 2.3 weeks in the RLA group (p = 0.02). During a mean followup of 6 years 2 patients in the TLA group had a late complication (port site hernia). Mortality occurred in 5 patients, including 1 with TLA and 4 with RLA, during the 6-year followup. For most benign adrenal lesions requiring surgery laparoscopic adrenalectomy can be performed safely and effectively by the transperitoneal or the retroperitoneal approach.

Robot-assisted laparoscopic surgery is being performed more frequently for the minimally invasive management of rectal cancer. The objective of this meta-analysis was to compare the clinical and oncologic safety and efficacy of robot-assisted versus conventional laparoscopic surgery. A search of the Medline and Embase databases was performed for studies that compared clinical or oncologic outcomes of conventional laparoscopic proctectomy with robot-assisted laparoscopic proctectomy for rectal cancer. The methodological quality of the selected studies was critically assessed to identify studies suitable for inclusion. Meta-analysis was performed by a random effects model and analyzed by Review Manager. Clinical outcomes evaluated were conversion rates, operation times, length of hospital stay, and complications. Oncologic outcomes evaluated were circumferential margin status, number of lymph nodes collected, and distal resection margin lengths. Eight comparative studies were assessed for quality, and seven studies were included in the meta-analysis. Two studies were matched case-control studies, and five were unmatched. A total of 353 robot-assisted laparoscopic surgery proctectomy cases and 401 conventional laparoscopic surgery proctectomy cases were analyzed. Robotic surgery was associated with a significantly lower conversion rate (P=0.03; 95% confidence interval 1-12). There was no difference in complications, circumferential margin involvement, distal resection margin, lymph node yield, or hospital stay (P=NS). Robot-assisted surgery decreased the conversion rate compared to conventional laparoscopic surgery. Other clinical outcomes and oncologic outcomes were equivalent. The benefits of robotic rectal cancer surgery may differ between population groups.

We aimed to explore the feasibility and the safety of the laparoscopic surgery for incarcerated indirect inguinal hernia (IIH) in children. From January 2012 to December 2014, 64 children were enrolled into this study. All 64 patients received laparoscopic surgery and we reviewed their perioperative and postoperative follow-up studies. In addition, we enrolled 60 cases of children who received traditional surgery of IIH administered through minimally invasive surgery as the control group. Results from the present study showed that the mean operation time for the laparoscopic group was 41.5 min (range, 15-80 min) which was significantly shorter than the control group. Nine cases developed incarcerated intestine necrosis, expanded umbilical incision and parallel resection anastomosis. They received laparoscopic hernia sac high ligation. Only 5 cases developed scrotum edema after the surgery. The postoperative length of the stay ranged from 2 to 7 days (average, 3.2). The postoperative follow-up was from 6 months to 1 year and no relapse or secondary testicular atrophy was observed in the laparoscopic group. The operation time, incidence of postoperative complications and length of stay in the laparoscopic group were decreased compared to the control group, and differences were statistically significant (P<0.05). In conclusion, laparoscopic surgery treatment for incarcerated inguinal hernia is safe and feasible and produced better results compared with the alternative.

Limited information exists comparing the post-operative complication rate of laparoscopic or open abdominal surgeries in children with sickle cell disease (SCD). The primary objective of this study was to compare the outcomes in children with SCD who required laparoscopic or open abdominal surgery for a cholecystectomy or splenectomy. We conducted a retrospective analysis of laparoscopic and open abdominal surgeries performed in children with SCD (ages 0-20 years) at two medical centers from 1984 to 2004. The primary outcome measures were the rates of post-operative pain and acute chest syndrome (ACS) episodes following laparoscopic or open abdominal surgery. The secondary outcome was length of hospital stay following surgery. We also examined the potential contribution of pre-operative (transfusion) and intra-operative factors (operating time, estimated blood loss, and end-operative temperature) to post-operative SCD-related complications. A total of 140 cases were identified, 98 laparoscopic and 42 open. Episodes of post-operative pain and ACS episodes were comparable between laparoscopic and open procedures (pain: 4% vs. 3%, P = 0.619; ACS: 5% vs. 5%, P = 0.933). Additionally, laparoscopic surgeries were associated with a significantly shorter hospital stay (2.9 vs. 5.4 days, 95% CI -3.7 to -1.4, P < 0.001). There was no difference in the number of hospital readmissions within 1 month of the surgery. For children with SCD who need a cholecystectomy or splenectomy, laparoscopy is the preferred strategy because of a shorter hospital stay with a similar complication rate compared to open surgeries.

Laparoscopic is performed in adults for the treatment of benign renal diseases. It is widely accepted that laparoscopic surgery has more advantages than open surgery in many procedures such as nephrectomy, but there is no further experience in this technique. In pediatric urology laparoscopy has become an accepted approach for varicocele, non palpable testis, bladder augmentation, adrenalectomy and urinary diversion. We report our experience with 25 laparoscopic nephrectomies in children.

Obstructive defecation syndrome (ODS) presents a common medical problem, which can be caused by various pelvic disorders; multiple disorders are frequently diagnosed. At the present, a high number of corrective techniques are available via various surgical approaches. Laparoscopic resection rectopexy is a minimally invasive technique, which comprises redundant sigmoidal resection with rectal mobilisation and fixation. The aim of this paper was to evaluate the safety and effectiveness of laparoscopic resection rectopexy in the treatment of patients with ODS. The evaluation was performed via our own patients data analysis and via literature search focused on laparoscopic resection rectopexy. In total, 12 patients with ODS undergoing laparoscopic resection rectopexy in University Hospital Ostrava during the study period (2012-2015) were included in the study. In our study group, mean age was 64.5 years and mean BMI was 21.9; the group included 11 women (91.6%). ODS was caused by multiple pelvic disorders in all patients. Dolichosigmoideum and rectal prolapse (internal or external) were diagnosed in all included patients. On top of that, rectocoele and enterocoele were diagnosed in several patients. Laparoscopic resection rectopexy was performed without intraoperative complications; mean operative time was 144 minutes. Mean postoperative length of hospital stay was 7 days. Postoperative 30-day morbidity was 16.6%. All postoperative complications were classified as grade II according to Clavien-Dindo classification. Mean preoperative Wexner score was 23.6 points; mean score 6 months after the surgery was 11.3 points. Significant improvement in ODS symptoms was noted in 58.3% of patients, and a slight improvement in 16.6% of patients; resection rectopexy provided no clinical effect in 25% of patients. It is fundamental to carefully select those patients with ODS who could possibly profit from the surgery. Our results, in accordance with published data, suggest that laparoscopic resection rectopexy is a valuable surgical technique in the treatment of patients with ODS caused by multiple pelvic disorders. obstructive defecation syndrome - constipation - resection rectopexy - operative techniques - pelvic floor disorders.

This is a case of a 33 weeks pregnant woman, presented 2 years after laparoscopic Roux-en-Y gastric bypass, with abdominal pain for 2 days. A laparoscopic cholecystectomy was performed 1 day earlier in another hospital, without improving the pain. She presented at our hospital with acute abdominal pain and clinical signs of intestinal obstruction, undergoing an exploratory laparotomy that revealed a volvulus and necrosis of the jejunum from the gastroenteroanastomosis through the lateral enteroenterostomy, which was resected with the reconstruction of the Roux-en-Y limb performed at the same operation. Patient and neonate presented with improvement after surgery and the patient was discharged on postoperative day 15. Internal hernias after bariatric surgery have been reported as the cause of acute abdomen problems during pregnancy, which may progress to necrosis and perforation. The delay of surgical intervention could have brought a tragic outcome for mother and neonate.

The aim of this study was to review the various anesthetic options which can be considered for laparoscopic surgeries in the patients with the chronic obstructive pulmonary disease. The literature search was performed in the Google, PubMed, and Medscape using key words “analgesia, anesthesia, general, laparoscopy, lung diseases, obstructive.” More than thirty-five free full articles and books published from the year 1994 to 2014 were retrieved and studied. Retrospective data observed from various studies and case reports showed regional anesthesia (RA) to be valid and safer option in the patients who are not good candidates of general anesthesia like patients having obstructive pulmonary diseases. It showed better postoperative patient outcome with respect to safety, efficacy, postoperative pulmonary complications, and analgesia. So depending upon disease severity RA in various forms such as spinal anesthesia, paravertebral block, continuous epidural anesthesia, combined spinal epidural anesthesia (CSEA), and CSEA with bi-level positive airway pressure should be considered.

Telemedicine is the use of electronic digital signals to transfer information from one site to another. With the advent of a telepresence operative system and development of remote robotic arms to hold and manoeuvre the laparoscope, telemedicine is finding its role in surgery, especially laparoscopic surgery. CLINICAL FEATURES AND TREATMENT: We report two successful cases of laparoscopic surgery--radical nephrectomy and varicocelectomy for a 3-cm renal tumour and for bilateral varicoceles causing pain, where a less experienced laparoscopic surgeon in Singapore was telementored by an experienced laparoscopic surgeon located remotely in the United States. Both patients recovered uneventfully and returned home on postoperative day 4 and on the day of surgery, respectively. This study demonstrates that telementored laparoscopic systems are feasible and safe, between countries halfway across the world. As the Internet expands in utility and the cost of higher bandwidth telecommunication lines decreases, even to remote countries, telementoring systems will become more affordable and may potentially pave the way for advanced surgical and laparoscopic applications and training for the future.

There is a scarcity of data on long-term results after laparoscopic hernia repair. Herein we report on the outcome of a group of patients who were followed up for 5 years in a multicenter study on hernia repair. A total of 100 patients with 127 hernias were randomized to undergo either transabdominal preperitoneal (TAPP) or Shouldice hernia repair. Follow-up was by clinical examination and standardized questionnaire. Of the 100 patients who underwent surgery, 84 were available for follow-up at 5 years. The TAPP procedure was less painful than the Shouldice repair, with fewer patients receiving narcotic analgesics. The median time to return to 100% activity was shorter in the laparoscopic group (21 days) than in the Shouldice group (40 days). Up to 60 months after the operation, the complication rate was lower in laparoscopically repaired hernias (19/66) than in the open group (25/61). There were two recurrences (3.9%) in the TAPP group and five in the Shouldice group (10.2%). The TAPP hernia repair yields comparable or better results than Shouldice herniorrhaphy in terms of postoperative pain, recovery, and recurrence rate.

Mini-laparoscopic cholecystectomy (MLC) has widened the horizons of modern laparoscopic surgery. Standard four port laparoscopic cholecystectomy (SLC), which has long been established as the "Gold Standard" for gall bladder diseases, is under reconsideration following the advent of further minimally-invasive procedures including MLC. Our study aims to provide a comparison between MLC and SLC and assesses whether MLC has any added benefits. Patients with symptomatic gall bladder disease undergoing MLC or SLC during the 2.5-month period were included in the study. Thirty-two patients underwent MLC while SLC was performed on 40 patients by the same surgeon. Data was collected prospectively and analysed retrospectively using a predesigned questionnaire. In our study, both the groups had similar age, body mass index (BMI) and gender distribution. No cases of MLC required insertion of additional ports. The mean operative time for MLC was 38.2 min (33-61 min), which is longer than SLC; but it was not statistically significant. There was no significant difference in mean operative blood loss, postoperative pain, analgesia requirement and mobilization. Patients who underwent MLC were able to return to normal activity earlier than patients undergoing SLC (P < 0.01). Our experience suggests that MLC can safely be used as an alternative to SLC. Compared to SLC, it has the added benefit of an early return to work along with excellent cosmetic results. Further large scale trials are required to prove any additional benefit of MLC.

The main stream of intraabdominal surgery has changed from laparotomy to laparoscopy, but anesthetic care for laparoscopic surgery is challenging for clinicians, because pneumoperitoneum might aggravate respiratory mechanics and arterial oxygenation. The authors reviewed the literature regarding ventilation strategies that reduce deleterious pulmonary physiologic changes during pneumoperitoneum for laparoscopic surgery under general anesthesia and make appropriate recommendations.

The porous diaphragm syndrome is associated with the presence of diaphragmatic fenestrations creating peritoneopleural communications. Such defects may occur in conditions associated with a rise on intra-abdominal pressure including laparoscopic surgery. Thoracic complications of laparoscopic surgery may occur as a result. A 48-year-old woman underwent a total laparoscopic hysterectomy for heavy menstrual bleeding. The postoperative period was complicated by haemoperitoneum resulting in haemothorax secondary to porous diaphragm syndrome. Surgeons and anaesthetists should be aware of the possibility of serious thoracic complications related to laparoscopic surgery.

To evaluate the comparative safety of laparoscopic and open colectomy across surgeons varying in experience with laparoscopy. National Medicare data (2008-2010) for beneficiaries undergoing laparoscopic or open colectomy. Using instrumental variable methods to address selection bias, we evaluated outcomes of laparoscopic and open colectomy. Our instrument was the regional use of laparoscopy in the year prior to a patient's operation. We then evaluated outcomes stratified by surgeons' annual volume of laparoscopic colectomy. Laparoscopic colectomy was associated with lower mortality (OR: 0.75, 95 percent CI: 0.70-0.78) and fewer complications than open surgery (OR: 0.82, 95 percent CI: 0.79-0.85). Increasing surgeon volume was associated with better outcomes for both procedures, but the relationship was stronger for laparoscopy. The comparative safety depended on surgeon volume. High-volume surgeons had 40 percent lower mortality (OR: 0.60, 95 percent CI: 0.55-0.65) and 30 percent fewer complications (OR: 0.70, 95 percent CI: 0.67-0.74) with laparoscopy. Conversely, low-volume surgeons had 7 percent higher mortality (OR: 1.07, 95 percent CI: 1.02-1.13) and 18 percent more complications (OR: 1.18, 95 percent CI: 1.12-1.24) with laparoscopy. This population-based study demonstrates that the comparative safety of laparoscopic and open colectomy is influenced by surgeon volume. Laparoscopic colectomy is only safer for patients whose surgeons have sufficient experience. © Health Research and Educational Trust.

Surgical site infection (SSI) prevention bundles include the simultaneous use of different measures, which individually have demonstrated an effect on prevention of SSI. The implementation of bundles can yield superior results to the implementation of individual measures. The aim of this study was to address the effect of the application of a bundle including intraperitoneal lavage with antibiotic solution, fascial closure with Triclosan-coated sutures and Mupirocin ointment application on the skin staples, on the surgical site infection after elective laparoscopic colorectal cancer surgery. A prospective, randomized study was performed, including patients with diagnosis of colorectal neoplasms and plans to undergo an elective laparoscopic surgery. The patients were randomized into two groups: those patients following standard bundles (Group 1) and those ones following the experimental bundle with three additional measures, added to the standard bundle. Incisional and organ space SSI were investigated. The study was assessor-blinded. A total of 198 patients were included in the study, 99 in each group. The incisional SSI rate was 16% in Group 1 and 2% in Group 2 [p = 0.007; RR = 5.6; CI 95% (1.4-17.8)]. The organ-space SSI rate was 4% in Group 1 and 0% in Group 2 [p = 0.039; RR = 1.7; CI 95% (1.1-11.6)]. Median hospital stay was 5.5 days in Group 1 and 4 days in Group 2 (p = 0.028). The addition of intraperitoneal lavage with antibiotic solution, fascial closure with Triclosan-coated sutures and Mupirocin ointment application on the skin staples, to a standard bundle of SSI prevention, reduces the incisional and organ-space SSI and consequently the hospital stay, after elective laparoscopic colorectal cancer surgery (ClinicalTrials.gov Identifier: NCT03081962).

The laparoscopic approach in colorectal complications is controversial because of its difficulty. However, it has been proven that it can provide advantages over open surgery. The aim of this study is to compare laparoscopic approach in reoperations for complications after colorectal surgery with the open approach taking into account the severity of the patient prior to reoperation. Patients who underwent laparoscopic colorectal surgery from January 2006 to December 2015 were retrospectively reviewed. Patients requiring urgent surgical procedures for complications in the postoperative period were divided in two groups: laparoscopic surgery (LS) and open surgery (OS). To control clinical severity prior to reoperation, The Mannheim Peritonitis Index (MPI) was calculated. A total of 763 patients were studied, 40 required urgent surgery (24 OS/16 LS). More ileostomies were performed in the LS group (68.7% vs. 29.2%) and more colostomies in the OS group (37.5% vs. 6.2%), p<0.05. MPI was higher in OS group (27.31±6.47 [19-35] vs. 18.36±7.16 [11-24], p<0.001). Hospital stay after re-intervention, oral tolerance and surgical wound infection, were favorable in LS (p<0.05 in all cases). In patients with MPI score ≤26, laparoscopic approach showed shorter hospital stay after re-intervention, less stay in the critical care unit after re-intervention, earlier start of oral tolerance and less surgical wound infection (p<0.05). A laparoscopic approach in re-intervention for complications after laparoscopic colorectal surgery associates a faster recovery reflected in a shorter hospital stay, earlier start of oral tolerance and a lower abdominal wall complication rate in patients with low severity index.

AIM: To evaluate the long-term clinical and oncological outcomes of laparoscopic rectal resection (LRR) and the impact of conversion in patients with rectal cancer. METHODS: An analysis was performed on a prospective database of 633 consecutive patients with rectal cancer who underwent surgical resection. Patients were compared in three groups: Open surgery (OP), laparoscopic surgery, and converted laparoscopic surgery. Short-term outcomes, long-term outcomes, and survival analysis were compared. RESULTS: Among 633 patients studied, 200 patients had successful laparoscopic resections with a conversion rate of 11.1% (25 out of 225). Factors predictive of survival on univariate analysis include the laparoscopic approach (P = 0.016), together with factors such as age, ASA status, stage of disease, tumor grade, presence of perineural invasion and vascular emboli, circumferential resection margin < 2 mm, and postoperative adjuvant chemotherapy. The survival benefit of laparoscopic surgery was no longer significant on multivariate analysis (P = 0.148). Neither 5-year overall survival (70.5% vs 61.8%, P = 0.217) nor 5-year cancer free survival (64.3% vs 66.6%, P = 0.854) were significantly different between the laparoscopic group and the converted group. CONCLUSION: LRR has equivalent long-term oncologic outcomes when compared to OP. Laparoscopic conversion does not confer a worse prognosis. PMID:27358678

Laparoscopic Suturing as a Barrier to Broader Adoption of Laparoscopic Surgery

Ghosh, Sudip; Niklewski, Paul; Roy, Sanjoy

2017-01-01

Background: Laparoscopic surgery is increasingly replacing the open procedure because of its many patient-related benefits that are well aligned with policies and programs that seek to optimize health system performance. However, widespread adoption of laparoscopic surgery has been slow, in part, because of the complexity of laparoscopic suturing. The objective of this study was to review the clinical and economic impacts of laparoscopic suturing in key procedures and to assess its role as a barrier to the broader adoption of laparoscopic surgery. Database: A medical literature search of MEDLINE, EMBASE, and BIOSIS from January 2010 through June 2016 identified 47 relevant articles. Conclusion: Laparoscopic suturing and intracorporeal knot tying may result in extended surgical time, complications, and surgeon errors, while improving patient quality of life through improved cosmesis, diet toleration, and better bowel movements. Despite advancement in surgical techniques and the availability of newer surgical tools, the complexity of laparoscopic suturing continues to be a barrier to greater adoption of MIS. The results of the study underscore the need for development of proficiency in laparoscopic suturing, which may help improve patient outcomes and reduce healthcare costs. PMID:28694682

The use of laparoscopic surgery has been well established for the management of abdominal emergencies. However, the value of this technique for postoperative hemorrhage in urology has not been characterized. We present our favorable experience with laparoscopic exploration after urologic surgery and suggest guidelines for laparoscopic management of post-laparoscopy bleeding. Three patients who developed hemorrhage shortly after laparoscopic urologic surgery and were managed by laparoscopic exploration were identified from a series of 910 laparoscopic urologic procedures performed at our institution from October 2002 to June 2006. Three patients, who were hemodynamically stable (two after robot-assisted laparoscopic prostatectomy, one after laparoscopic radical nephrectomy), required prompt surgical exploration for postoperative hemorrhage not stabilized by blood transfusion (mean 2.7 units) at a mean of 19.4 hours after initial surgery. Clots were evacuated with a 10-mm suction-irrigator. Two patients were found to have abdominal-wall arterial bleeding and were managed with suture ligation. The third patient demonstrated diffuse bleeding from the prostatic bed, which was controlled with Surgicel and FloSeal. Bleeding was efficiently controlled in all patients, and none required post-exploration transfusion. The mean post-exploration hospital stay was 2.3 days. Significant hemorrhage after urologic laparoscopy is a rare event. We found laparoscopic exploration to be an excellent way to diagnose and correct such hemorrhage in certain patients. Early diagnosis with clinical and hematologic studies, a lowered threshold for surgical exploration, and specific operative equipment may decrease patient morbidity and the need for open surgical exploration.

The aim of the study was to describe simultaneous laparoscopic adrenalectomy and laparoscopic nephron-sparing surgery, to discuss the details of a convenient laparoscopic approach and the way of port placement, as well as to present a review of the literature concerning combined laparoscopic procedures. A 72-year-old woman was admitted to our department because of a tumor of the right adrenal gland and a small tumor of the right kidney. The patient underwent simultaneous laparoscopic adrenalectomy and laparoscopic nephron-sparing surgery. The postoperative period was uncomplicated. The patient was discharged from the hospital on the 4th postoperative day. We believe that the proposed way of trocar placement would help to avoid a ‘rollover’ problem between the laparoscope and a Satinsky clamp or a ‘crossing swords’ problem between a Satinsky clamp and manipulators.

To potentially improve outcomes in pancreatic resection, robot-assisted pancreatic surgery has been introduced. This technique has possible advantages over laparoscopic surgery, such as its affordance of three-dimensional vision and increased freedom of movement of instruments. A systematic review was performed to assess the safety and feasibility of robot-assisted pancreatic surgery. The literature published up to 30 September 2011 was systematically reviewed, with no restrictions on publication date. Studies reporting on over five patients were included. Animal studies, studies not reporting morbidity and mortality, review articles and conference abstracts were excluded. Data were extracted and weighted means were calculated. A total of 499 studies were screened, after which eight cohort studies reporting on a total of 251 patients undergoing robot-assisted pancreatic surgery were retained for analysis. Weighted mean operation time was 404 ± 102 min (510 ± 107 min for pancreatoduodenectomy only). The rate of conversion was 11.0% (16.4% for pancreatoduodenectomy only). Overall morbidity was 30.7% (n = 77), most frequently involving pancreatic fistulae (n = 46). Mortality was 1.6%. Negative surgical margins were obtained in 92.9% of patients. The rate of spleen preservation in distal pancreatectomy was 87.1%. Robot-assisted pancreatic surgery seems to be safe and feasible in selected patients and, in left-sided resections, may increase the rate of spleen preservation.

Background To potentially improve outcomes in pancreatic resection, robot-assisted pancreatic surgery has been introduced. This technique has possible advantages over laparoscopic surgery, such as its affordance of three-dimensional vision and increased freedom of movement of instruments. A systematic review was performed to assess the safety and feasibility of robot-assisted pancreatic surgery. Methods The literature published up to 30 September 2011 was systematically reviewed, with no restrictions on publication date. Studies reporting on over five patients were included. Animal studies, studies not reporting morbidity and mortality, review articles and conference abstracts were excluded. Data were extracted and weighted means were calculated. Results A total of 499 studies were screened, after which eight cohort studies reporting on a total of 251 patients undergoing robot-assisted pancreatic surgery were retained for analysis. Weighted mean operation time was 404 ± 102 min (510 ± 107 min for pancreatoduodenectomy only). The rate of conversion was 11.0% (16.4% for pancreatoduodenectomy only). Overall morbidity was 30.7% (n = 77), most frequently involving pancreatic fistulae (n = 46). Mortality was 1.6%. Negative surgical margins were obtained in 92.9% of patients. The rate of spleen preservation in distal pancreatectomy was 87.1%. Conclusions Robot-assisted pancreatic surgery seems to be safe and feasible in selected patients and, in left-sided resections, may increase the rate of spleen preservation. Randomized studies should compare the respective outcomes of robot-assisted, laparoscopic and open pancreatic surgery. PMID:23216773

Hypothyroidism is associated with increased body weight. Weight gain may occur despite normal levels of serum thyroid stimulating hormone (TSH) and thyroxine (T4) achieved by replacement therapy. We evaluated the prevalence of patients on thyroid replacement for subnormal thyroid function who were operated on for morbid obesity and monitored their postoperative weight loss pattern. Data was identified from a prospectively accrued database of patients undergoing laparoscopic Roux-en-Y gastric bypass (LRYGBP) or laparoscopic adjustable gastric banding (LAGB) for morbid obesity from February 2000 to November 2001. All patients with subnormal thyroid function, diagnosed by past thyroid function tests and treated by an endocrinologist, who were on thyroid replacement therapy, were identified; 5 of these were matched for age, gender, preoperative body mass index (BMI) and surgical procedure (LRYGBP) to 5 non-hypothyroid patients. Weight loss at 3 and 9 months after surgery was compared between the 2 groups. 192 patients underwent LRYGBP (n=155) or LAGB (n=37). Of the 21 patients (10.9%) on thyroid replacement identified, 14 were primary, 4 were postablative, and 3 were post-surgical; 17 underwent LRYGBP. All patients had normal preoperative serum levels of TSH and T4. Comparison of the 2 matched groups of patients revealed no difference in weight loss at 3 and 9 months after surgery (P=1.0). The prevalence of euthyroid patients on thyroid replacement for subnormal thyroid function who undergo surgical intervention for morbid obesity is high. Short-term weight loss in these patients is comparable to normal thyroid patients. Longer follow-up may be necessary to demonstrate the weight loss pattern in this group.

It has been proven that bariatric surgery affects weight loss. Patients with morbid obesity have a significantly lower quality of life (QOL) and body image compared with the general population. To evaluate QOL, body image, and general self-efficacy (GSE) in patients with morbid obesity undergoing bariatric surgery within clinical parameters. Monocentric, prospective, longitudinal cohort study. Patients completed the short form 36 (SF-36) for QOL, body image questionnaire, and GSE scale 3 times: before surgery and within 6 months and 24 months after surgery. Influence of gender, age, and type of procedure, either laparoscopic sleeve gastrectomy (SG) or laparoscopic Roux-en-Y gastric bypass, were analyzed. Thirty patients completed the questionnaires before and within 6 and 24 months after surgery. SF-36 physical summary score improved significantly from 34.3±11.0 before surgery to 46.0±10.4 within 6 months (P<.001) and to 49.8±8.2 within 24 months (P<.001) after surgery. SF-36 mental summary score improved significantly from 42.1±14.7 before surgery to 52.3±8.4 within 6 months (P<.001) and to 48.4±12.2 within 24 months (P<.001) after surgery. There were no significant differences between gender, age, and type of operation. Body image and GSE improved significantly after bariatric surgery (P<.001), and both correlated to the SF-36 mental summary score. QOL, body image, and GSE improved significantly within 6 months and remained stable within 24 months after bariatric surgery. Improvements were independent of gender, age, and type of operation. Mental QOL was influenced by body image and GSE. Copyright © 2017 American Society for Bariatric Surgery. Published by Elsevier Inc. All rights reserved.

Cost Comparison of Laparoscopic versus Open Procedures at the Sydney Women's Endosurgery Centre

Chou, Danny; Cario, Gregory

1998-01-01

Objectives: The objective of this study was to provide a cost comparison between laparoscopic surgery and open surgery from January 1996 to January 1998. The setting for this study was three private hospitals and one public hospital associated with the Sydney Women's Endosurgery Centre. Cost analysis was done using the costing provided by the private and public hospitals representing the total amount charged to the patient or the fund for their entire stay including disposable laparoscopic instruments and miscellaneous charges. We looked at laparoscopic hysterectomy, abdominal hysterectomy, vaginal hysterectomy, laparoscopic Burch colposuspension and open Burch colposus-pension. Despite the difficulties and limitations using our method of cost analysis, it appears that laparoscopic surgery is a less costly alternative to open abdominal surgery, particularly where the amount of disposable instruments are kept to a minimum. When the added advantages of early return to normal activities, family and workplace are added in, it is clear that providers of health care in the public and private sector will see laparoscopic surgery as an increasingly desirable option.

Single incision laparoscopic surgery (SILS) may further reduce the trauma of surgery leading to reduced port site complications and postoperative pain. The improved cosmetic result also may lead to improved patient satisfaction with surgery. Data were prospectively collected and retrospectively analyzed for all patients who underwent SILS appendicectomy at our institution and were compared with those who had undergone conventional laparoscopic appendicectomy during the same time period. This included patient demographic data, intraoperative, and postoperative outcomes. Thirty-three patients underwent conventional laparoscopic appendicectomy and 40 patients underwent SILS appendicectomy between January 26, 2008 and July 14, 2009. Operative time was shorter with SILS appendicectomy compared with conventional laparoscopic appendicectomy (p < 0.05). No patients in the SILS appendicectomy group required conversion to open surgery compared with two patients in the conventional laparoscopic appendicectomy group. Patients stayed an average of 1.36 days after SILS appendicectomy, and 2.36 days after conventional laparoscopic appendicectomy. SILS appendicectomy seems to be a safe and efficacious technique. Further work in the form of randomized studies is required to investigate any significant advantages of this new and attractive technique.

We presented a series of single-incision laparoscopic distal gastrectomies for early gastric cancer patients through a type of homemade single port access device and some other conventional laparoscopic instruments. A single-incision laparoscopic distal gastrectomy with D1 + α lymph node dissection was performed on a 46 years old male patient who had an early gastric cancer. This single port access device has facilitated the conventional laparoscopic instruments to accomplish the surgery and we made in only 6 minutes. Total operating time for this surgery was 240 minutes. During the operation, there were about 100 milliliters of blood loss, and 17 lymph-nodes were retrieved. This homemade single port access device shows its superiority in economy and convenience for complex single-incision surgeries. Single-incision laparoscopic distal gastrectomy for early gastric cancer can be conducted by experienced laparoscopic surgeons. Fully take advantage of both SILS and fast track surgery plan can bring to successful surgeries with minimal postoperative pain, quicker mobilization, early recovery of intestinal function, and better cosmesis effect for the patients.

Background and Aims: Benefits of intraoperative low tidal volume ventilation during laparoscopic surgery are not conclusively proven, even though its advantages were seen in other situations with intraoperative respiratory compromise such as one-lung ventilation. The present study compared the efficacy of intraoperative low tidal volume ventilatory strategy (6 ml/kg along with positive end-expiratory pressure [PEEP] of 10 cmH2O) versus one with higher tidal volume (10 ml/kg with no PEEP) on various clinical parameters and plasma levels of interleukin (IL)-6 in patients undergoing laparoscopic cholecystectomy. Material and Methods: A total of 58 adult patients with American Society of Anesthesiologists physical status I or II, undergoing laparoscopic cholecystectomy were randomized to receive the low or higher tidal volume strategy as above (n = 29 each). The primary outcome measure was postoperative PaO2. Systemic levels of IL-6 along with clinical indices of intraoperative gas exchange, pulmonary mechanics, and hemodynamic consequences were measured as secondary outcome measures. Results: There was no statistically significant difference in oxygenation; intraoperative dynamic compliance, peak airway pressures, or hemodynamic parameters, or the IL-6 levels between the two groups (P > 0.05). Low tidal volume strategy was associated with significantly higher mean airway pressure, lower airway resistance, greater respiratory rates, and albeit clinically similar, higher PaCO2and lower pH (P < 0.05). Conclusion: Strategy using 6 ml/kg tidal volume along with 10 cmH2O of PEEP was not associated with any significant improvement in gas exchange, hemodynamic parameters, or systemic inflammatory response over ventilation with 10 ml/kg volume without PEEP during laparoscopic cholecystectomy.

Background: Familial adenomatous polyposis is a hereditary disease characterized by the presence of thousands of colonic adenomas, which, if untreated, invariably undergo malignant transformation. Because this disease manifests at a young age, the laparoscopic approach to perform surgery would be desirable due to its cosmetic benefits. We describe our experience with this procedure and review the literature on the topic. Methods: This is a case series of 15 patients who underwent restorative proctocolectomy with ileo-anal pouch anastomosis for familial adenomatous polyposis between 2000 and 2007. The salient operative steps are described. Results: There were 9 males and 6 females, 32 to 52 years of age, with an average age of 44.8 years. The median body mass index was 21.5 (range, 17 to 28). Rectal cancer was already present in 4 patients at the time of diagnosis. The median operating time was 225 minutes. Mean blood loss was 60mL, with none of the patients requiring perioperative blood transfusion. None of the surgeries required conversion to the open approach. Bowel function resumed on the second postoperative day in 12 patients and on the third postoperative day in 3 patients. The median hospital stay was 8 days. Postoperatively, there was no mortality and no serious morbidity. Conclusion: Laparoscopic restorative proctocolectomy with ileal pouch anal anastomosis is a feasible surgery for familial adenomatous polyposis, and considering its cosmetic benefit, is a desirable option for this group of predominantly young patients.

[Discussion on standardized implementation of laparoscopic radical lymphadenectomy for distal gastric cancer].

2017-08-25

Laparoscopic radical gastrectomy for gastric cancer has been widely applied in clinical practice, and its indications have been extended from early gastric cancer to advanced gastric cancer. It is acknowledged that laparoscopic radical gastrectomy is technically challenging because of the complexity of anatomy, rich blood supply, and extensive lymph node dissection. This paper primarily intends to share the experience of laparoscopic radical D2 gastrectomy for distal gastric cancer with details of choosing the location of Trocar, surgical approaches and the sequence of lymph node dissection. All the surgeries were performed at Department of General Surgery and Gastrointestinal Surgery, Guangdong General Hospital. The finding suggests that a correct laparoscopic Trocar placement is the foundation of adequate surgical field visualization. Under most circumstances, the observation hole should be around 2 cm below the umbilicus and the operating hole should be close to the bilateral clavicle midline. Furthermore, proper surgical approach and sequence of lymph node dissection are the prerequisites for successful laparoscopic radical D2 gastrectomy, as well as the reassurance of dissecting lymph node safely and comprehensively. The position of surgical team adopted in our center is that the surgeon stands to the left of the patient, with laparoscope operator stands in between patient's legs while the first assistant positions himself opposite the surgeon on the right side of the patient. This position correlates to the rules of sequential lymph node dissection, which is "from left to right", "from proximal to distal" and "from inferior to superior". Therefore, it is conductive to inferior and superior pylorus region dissection and it can effectively prevent subsidiary-injury. In our center, the procedure of lymph node dissection has been standardized: the initial step is to undergo station 4sb dissection and greater gastric curvature clearance; then change the patient's position to clean the sub-pyloric lymph node region and cut off the duodenum by linear stapler; followed by the clearance of inferior region of the pylorus and the upper margin of the pancreas; in the final step, the first and the third groups of lymph node dissection is performed. Although varied surgical approaches and sequences of lymph node dissection are applied in different hospitals, the techniques required for laparoscopic D2 radical gastrectomy for gastric cancer are sophisticated and advanced in general. Radical lymph node dissection is complicated, urging surgeons to familiarize themselves with the anatomy of gastric peripheral vascular system and characteristics of lymph node drainage. By designing and implementing effective strategies, such as formulating a regular team, positioning surgical team reasonably, changing a patient's posture during operation, choosing an appropriate surgical approach and following a logically sequence of lymph node dissection, surgeons can standardize the complete surgical procedure, which ultimately reduces bleeding during surgery and shortens the operative time.

To systematically review the published literature and describe the various techniques of bowel and mesentery retraction available for use in laparoscopic colorectal resection. A comprehensive search of the literature was undertaken using MESH terms 'retraction', 'laparoscopic' and 'colorectal'. All articles describing methods of retraction in laparoscopic colorectal surgery were included. Twelve methods of retraction in laparoscopic colorectal surgery were described. Five case-based series and three case studies were reported on 108 patients. Techniques were classified into those offering retraction of the small or large bowel or according to the mode of retraction. Many retraction methods are available to the surgeon varying in cost, invasiveness and complexity. Adequate retraction remains a challenge for optimal exposure and dissection during laparoscopic colorectal surgery. © 2013 The Authors Colorectal Disease © 2013 The Association of Coloproctology of Great Britain and Ireland.

Laparoscopic surgery is applied today worldwide to most digestive procedures. In some of them, such as cholecystectomy, Nissen’s fundoplication or obesity surgery, laparoscopy has become the standard in practice. In others, such as colon or gastric resection, the laparoscopic approach is frequently used and its usefulness is unquestionable. More complex procedures, such as esophageal, liver or pancreatic resections are, however, more infrequently performed, due to the high grade of skill necessary. As a result, there is less clinical evidence to support its implementation. In the recent years, robot-assisted laparoscopic surgery has been increasingly applied, again with little evidence for comparison with the conventional laparoscopic approach. This review will focus on the complex digestive procedures as well as those whose use in standard practice could be more controversial. Also novel robot-assisted procedures will be updated.

To structure the rate of intraoperative complications that requires an intraoperative or perioperative resolution. We perform a literature review of Medline database. The research was focused on intraoperative laparoscopic procedures inside the field of urological oncology. General rate of perioperative complications in laparoscopic urologic surgery is described to be around 12.4%. Most of the manuscripts published do not make differences between pure intraoperative, intraoperative with postoperative consequences and postoperative complications. We expose a narrative statement of complications, possible solutions and possible preventions for most frequent retroperitoneal and pelvic laparoscopic surgery. We expose the results with the following order: retroperitoneal laparoscopic surgery (radical nephrectomy, partial nephrectomy, nephroureterectomy and adrenalectomy) and pelvic laparoscopic surgery (radical prostatectomy and radical cystectomy). Intraoperative complications vary from different series. More scheduled reports should be done in order to better understand the real rates of complications.

The Hartmann's operation, although less frequently performed today, is still used when initial colonic anastomosis is too risky in the short term. However, the subsequent procedure to restore gastrointestinal continuity is associated with significant morbidity and mortality. The review of an institutional review board (IRB)-approved prospectively maintained database provided data on the Hartmann's reversal procedure performed by either laparoscopic or open technique at our institution. The data collected included: demographic data, operative approach, conversion for laparoscopic cases and perioperative morbidity and mortality. Over a 14-year period from January 1997 to August 2011, 74 Hartmann's reversal procedures were performed (laparoscopic surgery-49, open surgery-25). The average age was 55 years for the laparoscopic and 57 years for the open surgery group, respectively. Male patients represent 61% of both groups. There was no significant difference in operative time between the two groups (149 min vs 151 min; P = 0.95), and there was a tendency to lower morbidity (3/49-7.3% vs 4/25-16%; P = 0.24) in the laparoscopic surgery group. In the laparoscopic group, eight patients (16.3%) were converted to open surgery, mostly due to severe adhesions. The length of hospital stay was significantly shorter for the laparoscopic group (5 days vs 7 days; P = 0.44). The Hartmann's reversal procedure can be safely performed in the majority of the cases using a laparoscopic approach with a low morbidity rate and achieving a shorter hospital stay.

Objective To report the results from one of the eight original U.S. centers performing laparoscopic adjustable silicone gastric banding (LASGB), a new minimally invasive surgical technique for treatment of morbid obesity. Summary Background Data Laparoscopic adjustable silicone gastric banding is under evaluation by the Food & Drug Administration in the United States in an initial cohort of 300 patients. Methods Of 37 patients undergoing laparoscopic placement of the LASGB device, successful placement occurred in 36 from March 1996 to May 1998. Patients have been followed up for up to 4 years. Results Five patients (14%) have been lost to follow-up for more than 2 years but at last available follow-up (3–18 months after surgery) had achieved only 18% (range 5–38%) excess weight loss. African American patients had poor weight loss after LASGB compared with whites. The LASGB devices were removed in 15 (41%) patients 10 days to 42 months after surgery. Four patients underwent simple removal; 11 were converted to gastric bypass. The most common reason for removal was inadequate weight loss in the presence of a functioning band. The primary reasons for removal in others were infection, leakage from the inflatable silicone ring causing inadequate weight loss, or band slippage. The patients with band slippage had concomitant poor weight loss. Bands were removed in two others as a result of symptoms related to esophageal dilatation. In 18 of 25 patients (71%) who underwent preoperative and long-term postoperative contrast evaluation, a significantly increased esophageal diameter developed; of these, 13 (72%) had prominent dysphagia, vomiting, or reflux symptoms. Of the remaining 21 patients with bands, 8 currently desire removal and conversion to gastric bypass for inadequate weight loss. Six of the remaining patients have persistent morbid obesity at least 2 years after surgery but refuse to undergo further surgery or claim to be satisfied with the results. Overall, only four patients achieved a body-mass index of less than 35 and/or at least a 50% reduction in excess weight. Thus, the overall need for band removal and conversion to GBP in this series will ultimately exceed 50%. Conclusions The authors did not find LASGB to be an effective procedure for the surgical treatment of morbid obesity. Complications after LASGB include esophageal dilatation, band leakage, infection, erosion, and slippage. Inadequate weight loss is common, particularly in African American patients. More study is required to determine the long-term efficacy of the LASGB PMID:11371739

Ultrasound-guided rectus sheath block and local anesthetic infiltration are the standard options to improve postoperative pain for children undergoing surgery with a midline incision. However, there is no study comparing the effect of ultrasound-guided rectus sheath block with local anesthetic infiltration for children undergoing laparoscopic surgery. The aim of this trial was to compare the onset of ultrasound-guided rectus sheath block with that of local anesthetic infiltration for laparoscopic percutaneous extraperitoneal closure in children. We performed an observer-blinded, randomized, prospective trial. Enrolled patients were assigned to either an ultrasound-guided rectus sheath block group or a local anesthetic infiltration group. The ultrasound-guided rectus sheath block group (n = 17) received ultrasound-guided rectus sheath block with 0.2 ml·kg -1 of 0.375% ropivacaine per side in the posterior rectus sheath compartment. The local anesthetic infiltration group (n = 17) received local anesthetic infiltration with 0.2 ml·kg -1 of 0.75% ropivacaine. The Face, Legs, Activity, Cry, and Consolability (FLACC) pain scores were recorded at 0, 30, 60 min after arrival at the postanesthesia care unit. Of the 37 patients enrolled in this study, 34 completed the study protocol. A significant difference in the pain scale between the ultrasound-guided rectus sheath block group and local anesthetic infiltration group was found at 0 min (median: 0, interquartile range [IQR]: 0-1.5, vs median: 1, IQR 0-5, confidence interval of median [95% CI]: 0-3, P = 0.048), but no significant difference was found at 30 min (median: 1, IQR: 0-4 vs median: 6, IQR: 0-7, 95% CI: 0-5, P = 0.061), or 60 min (median: 0, IQR: 0-2 vs median: 1, IQR: 0-3, 95% CI: -1 to 1, P = 0.310). No significant difference was found in anesthesia time between the ultrasound-guided rectus sheath block and local anesthetic infiltration groups. No procedure-related complications were observed in either group. Ultrasound-guided rectus sheath block is a quicker way to control postoperative pain for pediatric patients undergoing laparoscopic extraperitoneal closure than local anesthetic infiltration, and thus may provide a clinical benefit. © 2017 John Wiley & Sons Ltd.

Single port laparoscopic right hemicolectomy for ileocolic intussusception

A 36-year-old male was admitted with right lower abdominal pain and diarrhea for more than 3 mo. Colonoscopy and a barium enema study revealed a submucosal tumor over the cecum, but computed tomography showed an ileal lipoma. There was no definitive diagnosis preoperatively, but ileocolic intussusception was noted during surgery. Single port laparoscopic radical right hemicolectomy was performed because intra-operative reduction failed. The histological diagnosis of the resected tumor was lipoma. Single port laparoscopic surgery has recently been proven to be safe and feasible. There are advantages compared with conventional laparoscopic surgery, such as smaller incision wounds, fewer port site complications, and easier conversion. However, there are some drawbacks which need to be overcome, such as difficulties in triangulation and instrument clashing. If there are no contraindications to laparoscopy, single port laparoscopic surgery can be performed safely and should be considered for diagnosis and treatment of intussusception in adults. Here, we report the first case of ileocolic intussusception successfully treated by single port laparoscopic surgery. PMID:23538552

Four patients among a total of 2814 patients with a postoperative pneumothorax. Laparoscopic surgery for gynecologic benign disease. The main outcome was the clinical frequency and characteristics of the patients with postoperative pneumothorax. We observed 4 (0.14%) cases of postoperative pneumothorax after laparoscopic surgery, all of whom were diagnosed with endometriomas and developed a right-sided pneumothorax. The incidence of postoperative pneumothorax in 1097 patients with endometriomas was 0.36%, which was significantly higher than those without endometriomas. The presence of endometrioma should be considered a risk factor for postoperative pneumothorax in gynecologic laparoscopic surgery. Copyright © 2015 AAGL. Published by Elsevier Inc.

Controversy of hand-assisted laparoscopic colorectal surgery

PubMed Central

Meshikhes, Abdul-Wahed Nasir

2010-01-01

Laparoscopically assisted colorectal procedures are time-consuming and technically demanding and hence have a long steep learning curve. In the technical demand, surgeons need to handle a long mobile organ, the colon, and have to operate on multiple abdominal quadrants, most of the time with the need to secure multiple mesenteric vessels. Therefore, a new surgical innovation called hand-assisted laparoscopic surgery (HALS) was introduced in the mid 1990s as a useful alternative to totally laparoscopic procedures. This hybrid operation allows the surgeon to introduce the non-dominant hand into the abdominal cavity through a special hand port while maintaining the pneumoperitoneum. A hand in the abdomen can restore the tactile sensation which is usually lacking in laparoscopic procedures. It also improves the eye-to-hand coordination, allows the hand to be used for blunt dissection or retraction and also permits rapid control of unexpected bleeding. All of those factors can contribute tremendously to reducing the operative time. Moreover, this procedure is also considered as a hybrid procedure that combines the advantages of both minimally invasive and conventional open surgery. Nevertheless, the exact role of HALS in colorectal surgery has not been well defined during the advanced totally laparoscopic procedures. This article reviews the current status of hand-assisted laparoscopic colorectal surgery as a minimally invasive procedure in the era of laparoscopic surgery. PMID:21128315

The introduction of laparoscopic surgery into urology has led to new training concepts differing significantly from previous concepts of training for open surgery. This paper focuses on the type and importance of mechanical simulators in laparoscopic training. On the basis of our own studies and experience with the development of various concepts of laparoscopic training, including different modules (i.e., Pelvi-trainer, animal models, clinical mentoring) since 1991, we reviewed the current literature concerning all types of simulators. We focused on training for laparoscopic ablative and reconstructive surgery using mechanical simulators. The principle of a mechanical simulator (i.e., a box with the possibility of trocar insertion) has not changed during the last decade. However, the types of Pelvi-trainers and the models used inside have been improved significantly. According to the task of the simulator, various sophisticated models have been developed, including standardized phantoms, animal organs, and even perfused segments of porcine organs. For laparoscopic suturing, various step-by-step training concepts have been presented. These can be used for determination of the ability of a physician with an interest in laparoscopic surgery, but also to classify the training status of a laparosopic surgeon. Training in laparoscopic surgery has become an important topic, not only in learning a procedure, but also in maintaining skills and preparing for the management of complications. For these purposes, mechanical simulators will definitely play an important role in the future.

Laparoscopic cholecystectomy (LC) is the operation of choice in the treatment of symptomatic gallstone disease. The aim of this study is to identify risk factors for LC, outcomes include operating time, length of stay, conversion rate, morbidity and mortality. All patients undergoing LC between 1998 and 2007 in a single district general hospital. Risk factors were examined using uni- and multivariate analysis. 2117 patients underwent LC, with 1706 (80.6%) patients operated on electively. Male patients were older, had more co-morbidity and more emergency surgery than females. The median post-operative hospital stay was one day, and was positively correlated with the complexity of surgery. Conversion rates were higher in male patients (OR 1.47, p = 0.047) than in females, and increased with co-morbidity. Emergency surgery (OR 1.75, p = 0.005), male gender (OR 1.68, p = 0.005), increasing co-morbidity and complexity of surgery were all positively associated with the incidence of complications (153/2117 [7.2%]), whereas only male gender was significantly associated with mortality (OR 5.71, p = 0.025). Adverse outcome from LC is particularly associated with male gender, but also the patient's co-morbidity, complexity and urgency of surgery. Risk-adjusted outcome analysis is desirable to ensure an informed consent process. Copyright © 2011 Surgical Associates Ltd. Published by Elsevier Ltd. All rights reserved.

To investigate the correlation and accuracy of transcutaneous carbon dioxide partial pressure (PTCCO2) with regard to arterial carbon dioxide partial pressure (PaCO2) in severe obese patients undergoing laparoscopic bariatric surgery. Twenty-one patients with BMI>35 kg/m2 were enrolled in our study. Their PaCO2, end-tidal carbon dioxide partial pressure (PetCO2), as well as PTCCO2 values were measured at before pneumoperitoneum and 30 min, 60 min, 120 min after pneumoperitoneum respectively. Then the differences between each pair of values (PetCO2–PaCO2) and. (PTCCO2–PaCO2) were calculated. Bland–Altman method, correlation and regression analysis, as well as exact probability method and two way contingency table were employed for the data analysis. 21 adults (aged 19–54 yr, mean 29, SD 9 yr; weight 86–160 kg, mean119.3, SD 22.1 kg; BMI 35.3–51.1 kg/m2, mean 42.1,SD 5.4 kg/m2) were finally included in this study. One patient was eliminated due to the use of vaso-excitor material phenylephrine during anesthesia induction. Eighty-four sample sets were obtained. The average PaCO2–PTCCO2 difference was 0.9±1.3 mmHg (mean±SD). And the average PaCO2–PetCO2 difference was 10.3±2.3 mmHg (mean±SD). The linear regression equation of PaCO2–PetCO2 is PetCO2 = 11.58+0.57×PaCO2 (r2 = 0.64, P<0.01), whereas the one of PaCO2–PTCCO2 is PTCCO2 = 0.60+0.97×PaCO2 (r2 = 0.89). The LOA (limits of agreement) of 95% average PaCO2–PetCO2 difference is 10.3±4.6 mmHg (mean±1.96 SD), while the LOA of 95% average PaCO2–PTCCO2 difference is 0.9±2.6 mmHg (mean±1.96 SD). In conclusion, transcutaneous carbon dioxide monitoring provides a better estimate of PaCO2 than PetCO2 in severe obese patients undergoing laparoscopic bariatric surgery. PMID:24699267

Laparoscopic surgery for rectal cancer offers favorable short term results without compromising long term oncological outcomes so far, according to the data from major trials. Therefore it is being considered as a standard option for rectal cancer surgery. The learning curve of laparoscopic rectal cancer surgery is generally longer compared to colon cancer. Appropriate standardization and training of laparoscopic rectal cancer surgery is required. Several RCTs suggested the potential negative effect on quality of resected specimen, which can increase local recurrence. The long term outcomes especially local recurrence rate of these RCTs are awaited. Lateral pelvic lymph node dissection (LPLND) has a certain effect of reducing local recurrence of rectal cancer even after neoadjuvant radiotherapy. Since LPLND is associated with postoperative morbidity, we should carefully select the candidate to maximize the effect of LPLND and minimize the morbidity caused by LPLND. Recent advancement in imaging study such as CT and MRI enables us to find the suitable candidates for LPLND. The morbidity caused by LPLND could be reduced by minimally invasive surgeries such as laparoscopic surgery and robotic surgery. We have to improve oncological outcomes and reduce morbidity by the multidisciplinary strategy for rectal cancer including total mesorectal excision, neoadjuvant chemoradiotherapy and LPLND together with laparoscopic surgery.

Background and Objective: The Harmonic ACE+7 Shears with Advanced Hemostasis Mode (Ethicon, Somerville, NJ, USA) is an ultrasonic device designed to transect and seal vessels up to 7 mm in diameter. The device applies an algorithm that optimizes ultrasonic energy delivery combined with a longer sealing cycle. The purpose of this study was to assess the initial clinical experience with the Harmonic device by evaluating large-vessel sealing during laparoscopic colectomy in consecutive cases. Methods: This prospective, multicenter, observational series involved 40 adult patients who were to undergo elective laparoscopic colectomy where dissection and transection of the inferior mesenteric artery was indicated. The primary study endpoint was first-pass hemostasis, defined as a single activation of the Advanced Hemostasis Mode to transect and seal the inferior mesenteric artery. The use of any additional energy device or hemostatic product to establish or maintain hemostasis was noted. Patients were observed after surgery for ∼4 weeks for adverse events that were considered to be related to the study procedure or study device. Descriptive statistical analyses were performed for study endpoints. Results: Forty patients underwent the laparoscopic colectomy procedure. First-pass hemostasis of the inferior mesenteric artery was achieved and maintained in all 40 patients, with no required additional hemostatic measures. Exposure of the vessel was reported as skeletonized in 22 of 40 (55%) patients. Mean transection time was 21.9 ± 7.4 s. One adverse event (postoperative anemia) was considered possibly related to the study device. Conclusion: In this initial clinical consecutive series, the device demonstrated successful transection and sealing of the large mesenteric vessels during laparoscopic colorectal surgery.

Carbon dioxide is the standard insufflation gas for laparoscopy. However, in many areas of the world, bottled carbon dioxide is not available. Laparoscopy offers advantages over open surgery and has been practiced using filtered room air insufflation since 2006 at Bongolo Hospital in Gabon, Africa. Our primary goal was to evaluate the safety of room air insufflation related to intraoperative and postoperative complications. Our secondary aim was to review the types of cases performed laparoscopically at our institution. This retrospective review evaluates laparoscopic cases performed at Bongolo Hospital between January 2006 and December 2013. Demographic and perioperative information for patients undergoing laparoscopic procedures was collected. Insufflation was achieved using a standard, oil-free air compressor using filtered air and a standard insufflation regulator. A total of 368 laparoscopic procedures were identified within the time period. The majority of cases were gynecologic (43%). There was a 2% (8/368) complication rate with one perioperative death. The 2 complications related to insufflation were episodes of hypotension responsive to standard corrective measures. No intracorporeal combustion events were observed in any cases in which the use of diathermy and room air insufflation were combined. The other complications and the death were unrelated to the use of insufflation with air. Insufflation complications with room air occurred in our study. However, the complications related to insufflation with room air in our study were no different than those described in the literature using carbon dioxide. As room air is less costly than carbon dioxide and readily available, confirming the safety of room air insufflation in prospective studies is warranted. Room air appears to be safe for establishing and maintaining pneumoperitoneum, making laparoscopic surgery more accessible to patients in low-resource settings.

The use of endoscopic submucosal dissection (ESD) for duodenal neoplasms has increased in recent years, but delayed perforation and bleeding are also known to frequently occur. We present two cases in which duodenal adenoma was successfully treated with laparoscopic-endoscopic cooperative surgery. ESD was combined with laparoscopic seromuscular sutures. The lesions in both cases were located in the second portion of the duodenum. The patients requested resection of the lesion, and we performed laparoscopic-endoscopic cooperative surgery. After the laparoscopic surgeon mobilized the duodenum, the endoscopic surgeon performed ESD for the duodenal tumor without perforation. The laparoscopic surgeon sutured the duodenal wall in the seromuscular layer to strengthen the ulcer bed after ESD. Histopathological studies confirmed that the surgical margins were tumor-free in both cases. The patients were discharged with no complications. This unique laparoscopic-endoscopic cooperative procedure is a safe and effective method for resecting superficial nonampullary duodenal tumors. © 2015 Japan Society for Endoscopic Surgery, Asia Endosurgery Task Force and Wiley Publishing Asia Pty Ltd.

This study evaluated the learning curve for a second-year general surgery resident and compared 2 totally laparoscopic aortic surgery techniques in 10 pigs: the transretroperitoneal apron approach and the transperitoneal retrocolic approach. Five end points were compared: success rate, percentage of conversion, time required, laparoscopic anastomosis quality, and learning curve. The first 3 interventions required an open conversion. The last 7 were done without complications. Mean dissection time was significantly higher with the apron approach compared with the retrocolic approach. The total times for operation, clamping, and arteriotomy time were similar. All laparoscopic anastomoses were patent and without stenosis. The initial learning curve for laparoscopic anastomosis was relatively short for a second-year surgery resident. Both techniques resulted in satisfactory exposure of the aorta and similar mean operative and clamping time. Training on an ex vivo laparoscopic box trainer and on an animal model seems to be complementary to decrease laparoscopic anastomosis completion time.

In this case report, we discuss single-incision laparoscopic cecectomy for low-grade appendiceal neoplasm after laparoscopic anterior resection for rectal cancer. The optimal surgical therapy for low-grade appendiceal neoplasm is controversial; currently, the options include appendectomy, cecectomy, right hemicolectomy, and open or laparoscopic surgery. Due to the risk of pseudomyxoma peritonei, complete resection without rupture is necessary. We have encountered 5 cases of low-grade appendiceal neoplasm and all 5 patients had no lymph node metastasis. We chose the appendectomy or cecectomy without lymph node dissection if preoperative imaging studies did not suspect malignancy. In the present case, we performed cecectomy without lymph node dissection by single-incision laparoscopic surgery (SILS), which is reported to be a reduced port surgery associated with decreased invasiveness and patient stress compared with conventional laparoscopic surgery. We are confident that SILS is a feasible alternative to traditional surgical procedures for borderline tumors, such as low-grade appendiceal neoplasms. PMID:24868331

Laparoscopic sleeve gastrectomy (LSG) for morbid obesity is gaining in popularity as it offers several advantages over laparoscopic Roux-en-Y gastric bypass (LRYGBP), but comparative data between these two procedures have rarely been reported. This case control study compared the incidence of low-grade systemic inflammation, insulin resistance, anthropometrics, resting energy expenditure and metabolic syndrome in 30 patients undergoing LRYGBP and 30 patients undergoing LSG, matched for age, sex, body mass index (BMI), and glycosylated hemoglobin (HbA1c). At 1-year after surgery, the percent of excess weight loss was 67.8 ± 20.9 for LRYGBP and 61.6 ± 19.4 for LSG. Patients undergoing LRYGBP showed significantly lower plasma levels of C-reactive protein (3.3 ± 2.7 mg/dL vs. 5.3 ± 3.9 mg/dL; P < 0.05), waist circumference (97.4 ± 16.0 vs. 105.5 ± 14.7 cm; P < 0.05), total cholesterol (4.6 ± 1.0 vs. 5.7 ± 0.9 mmol/L; P < 0.01) and LDL cholesterol (2.6 ± 0.8 vs. 3.6 ± 0.8 mmol/L; P < 0.01). Insulin resistance (HOMA index 1.6 ± 1.0 after LRYGBP vs. 2.3 ± 2.4 after LSG), resting energy expenditure (1666.7 ± 320.5 after LRYGBP vs. 1600.4 ± 427.3 Kcal after LSG) and remission of metabolic syndrome (92.9% after LRYGBP vs. 80% after LSG) were not different between the two groups. In this study, patients undergoing LRYGBP demonstrated significantly improved lipid profiles, decreased systemic low-grade inflammation compared with those undergoing LSG at 1-year follow-up.

Laparoscopic surgery developed continuously over the past years becoming the gold standard for some surgical interventions. Laparoscopic colorectal surgery is well established as a safe and feasible procedure to treat benign and malignant pathologies. In this paper we studied in deep the role of laparoscopic right colectomy analysing the indications to this surgical procedure and the factors related to the conversion from laparoscopy to open surgery. We described the different surgical techniques of laparoscopic right colectomy comparing extra to intracorporeal anastomosis and we pointed out the different ways to access to the abdomen (multiport VS single incision). The indications for laparoscopic right colectomy are benign (inflammatory bowel disease and rare right colonic diverticulitis) and malignant diseases (right colon cancer and appendiceal neuroendocrine neoplasm): we described the good outcomes of laparoscopic right colectomy in all these illnesses. Laparoscopic conversion rates in right colectomy are reported as 12-16%; we described the different type of risk factors related to open conversion: patient-related, disease-related and surgeon-related factors, procedural factors and intraoperative complications. We conclude that laparoscopic right colectomy is considered superior to open surgery in the shortterm outcomes without difference in long-term outcomes.

Laparoscopy has been widely used to perform abdominal surgeries, as it is advantageous in that the patients experience lower post-surgical trauma, shorter convalescence, and less pain as compared to traditional surgery. Laparoscopic surgeries require precision; therefore, it is imperative to train surgeons to reduce the risk of operation. Laparoscopic simulators offer a highly realistic surgical environment by using virtual reality technology, and it can improve the training efficiency of laparoscopic surgery. This paper presents a virtual Laparoscopic surgery system. The proposed system utilizes the Visible Chinese Human (VCH) to construct the virtual models and simulates real-time deformation with both improved special mass-spring model and morph target animation. Meanwhile, an external device that integrates two five-degrees-of-freedom (5-DOF) manipulators was designed and made to interact with the virtual system. In addition, the proposed system provides a modular tool based on Unity3D to define the functions and features of instruments and organs, which could help users to build surgical training scenarios quickly. The proposed virtual laparoscopic training system offers two kinds of training mode, skills training and surgery training. In the skills training mode, the surgeons are mainly trained for basic operations, such as laparoscopic camera, needle, grasp, electric coagulation, and suturing. In the surgery-training mode, the surgeons can practice cholecystectomy and removal of hepatic cysts by guided or non-guided teaching.

The purpose of this study was to examine the adoption trends of emergency laparoscopic colorectal surgery in the province of Ontario. We conducted a retrospective time-series analysis examining rates of emergency colorectal surgery among 10.5 million adults in Ontario, Canada from April 1, 2002 to December 31, 2009. We linked administrative claims databases and the Ontario Cancer Registry to assess procedure rates over time. Procedure trends were assessed using time-series analysis. Over the 8-year period, 29,676 emergency colorectal procedures were identified. A total of 2582 (8.7%) were performed laparoscopically and 27,094 (91.3%) were open. Open and laparoscopic patients were similar with respect age, sex, and Charlson Comorbidity Index. The proportion of surgery for benign (63.8% of open cases vs. 65.6% laparoscopic, standardized difference=0.04) and malignant disease (36.2% open vs. 34.4% laparoscopic, standardized difference=0.04) was equal between groups. The percentage of emergency colorectal surgery performed laparoscopically increased from 5.7% in 2002 to 12.0% in 2009 (P<0.01). The use of laparoscopy increased for both benign and malignant disease. Statistically significant upward trends in laparoscopic surgery were seen for inflammatory bowel disease (P<0.01), obstruction (P<0.01), and colon cancer (P<0.01). From 2002 to 2009, annual procedure rates increased at a greater rate in nonacademic centers (P<0.01). Laparoscopic emergency colorectal surgery has increased significantly between 2002 and 2009 for both benign and malignant disease and for a wide range of diagnoses. This was driven in part by steadily rising usage of laparoscopy in nonacademic centers.

Laparoscopic colorectal surgery: Current status and implementation of the latest technological innovations.

The introduction of laparoscopy is an example of surgical innovation with a rapid implementation in many areas of surgery. A large number of controlled studies and meta-analyses have shown that laparoscopic colorectal surgery is associated with the same benefits than other minimally invasive procedures, including lesser pain, earlier recovery of bowel transit and shorter hospital stay. On the other hand, despite initial concerns about oncological safety, well-designed prospective randomized multicentre trials have demonstrated that oncological outcomes of laparoscopy and open surgery are similar. Although the use of laparoscopy in colorectal surgery has increased in recent years, the percentages of patients treated with surgery using minimally invasive techniques are still reduced and there are also substantial differences among centres. It has been argued that the limiting factor for the use of laparoscopic procedures is the number of surgeons with adequate skills to perform a laparoscopic colectomy rather than the tumour of patients' characteristics. In this regard, future efforts to increase the use of laparoscopic techniques in colorectal surgery will necessarily require more efforts in teaching surgeons. We here present a review of recent controversies of the use of laparoscopy in colorectal surgery, such as in rectal cancer operations, the possibility of reproducing complete mesocolon excision, and the benefits of intra-corporeal anastomosis after right hemicolectomy. We also describe the results of latest innovations such as single incision laparoscopic surgery, robotic surgery and natural orifice transluminal endoscopic surgery for colon and rectal diseases.

Rao, M M; Jayne, D

2011-05-01

  In spite of recent advances in technology and technique, laparoscopic colorectal surgery is associated with increased operating times when compared with open surgery. This increases the risk of acute lower limb compartment syndrome. The aim of this review was to gain a better understanding of postoperative lower limb compartment syndrome following laparoscopic colorectal surgery and to suggest strategies to avoid its occurrence. A MEDLINE search was performed using the keywords 'compartment syndrome', 'laparoscopic surgery' and 'Lloyd-Davies position' between 1970 and 2008. All relevant articles were retrieved and reviewed. A total of 54 articles were retrieved. Of the 30 articles in English, five were reviews, six were original articles and 19 were case reports, of which only one was following laparoscopic colorectal surgery. The remaining 24 were non-English articles. Of these, two were reviews and 22 were case reports, of which only one was following laparoscopic colorectal surgery. The incidence of acute compartment syndrome following laparoscopic colorectal surgery is unknown. The following are believed to be risk factors for acute lower limb compartment syndrome: the Lloyd-Davies operating position with exaggerated Trendelenburg tilt, prolonged operative times and improper patient positioning. Simple strategies are suggested to reduce its occurrence. Simple preventative measures have been identified which may help to reduce the incidence of acute lower limb compartment syndrome. However, if suspected, timely surgical intervention with four-compartment fasciotomy remains the standard of care. © 2011 The Authors.

AIM: To structure the rate of intraoperative complications that requires an intraoperative or perioperative resolution. METHODS: We perform a literature review of Medline database. The research was focused on intraoperative laparoscopic procedures inside the field of urological oncology. General rate of perioperative complications in laparoscopic urologic surgery is described to be around 12.4%. Most of the manuscripts published do not make differences between pure intraoperative, intraoperative with postoperative consequences and postoperative complications. RESULTS: We expose a narrative statement of complications, possible solutions and possible preventions for most frequent retroperitoneal and pelvic laparoscopic surgery. We expose the results with the following order: retroperitoneal laparoscopic surgery (radical nephrectomy, partial nephrectomy, nephroureterectomy and adrenalectomy) and pelvic laparoscopic surgery (radical prostatectomy and radical cystectomy). CONCLUSION: Intraoperative complications vary from different series. More scheduled reports should be done in order to better understand the real rates of complications. PMID:25984519

Nature versus nurture: identical twins and bariatric surgery.

Genetics and environment both play a role in weight maintenance. Twin studies may help clarify the influence of nature vs nurture in weight loss. We present the largest U.S. experience with monozygotic (MZ) twins undergoing bariatric surgery. We retrospectively reviewed the charts of four sets of MZ twins who underwent Roux-en-Y gastric bypass (RYGBP) surgery and laparoscopic adjustable gastric band (LAGB) placement at three different institutions. BMI and co-morbidities were examined pre- and postoperatively, and laboratory values were recorded. All four sets of twins are female, live together, and have similar professions. Twin cohort 1 had near identical weight loss patterns after open RYGBP surgery in 1996 (preop 146/142 kg; 2 years 82/82; and 10 years 108/107). Twin cohort 1 also both underwent cholecystectomies within the first year postoperatively. Twin cohort 2 underwent laparoscopic RYGBP surgery and also required cholecystectomies in the first postoperative year. Cohort 2 also experienced nearly identical weight loss at 1 year (36.7% vs 37.0% BMI loss). Twin cohort 3 underwent LAGB placement with two different surgeons with differing amounts of weight loss at 6 months (6.5% vs 15.7% BMI loss). Finally, twin cohort 4 underwent laparoscopic RYGBP with 2-year BMI loss of 39% vs 34%. In twin cohort 4, the twin who lost less weight lived apart from her twin and extended family, and her weight loss was less than the twin living with her family. Two sets of MZ twins had identical responses to bariatric surgery. The other two sets of identical twins had differential weight loss results, possibly due to differences in surgical approach and social support. While genetics do exert a strong influence on weight loss and maintenance, this case series demonstrates the potential effect of social support and postoperative management upon postoperative weight loss in the presence of identical genetics.

We have 3 options when perfoming prostatectomy for the treatment of localized prostate cancer. Those are retropubic radical prostatectomy, laparoscopic radical prostatectomy and robot-assisted laparoscopic radical prostatectomy. We compared the characteristics and results of these techniques. Robot-assisted laparoscopic radical prostatectomy could be superior to the others in many ways. However, it would be very difficult to adopt it in Japan because it would pose economical difficulties. The administrative assistance in the insurance systems requireds much more than we have.

Achalasia is a rare disorder that has several treatment options. The gold standard of treatment is a surgical myotomy called a laparoscopic Heller myotomy (LHM). More recently, an endoscopic myotomy has become an option as well, called per-oral endoscopic myotomy (POEM). An achalasia registry was queried for patients undergoing either LHM or POEM at Baylor University Medical Center at Dallas. Patient demographics, preoperative and postoperative data points, and Eckardt scores were collected. The patients were further stratified into their follow-up intervals, immediate postoperative and long-term follow-up, to assess surgical success. A subset analysis was done for success of treatment for patients who had redo surgery versus those undergoing the procedure for the first time. There were 12 patients in the POEM group and 11 patients in the LHM group. Both groups demonstrated mean lower esophageal sphincter pressures with failure to relax. Procedure length and hospital length of stay were similar between the two groups. There were three adverse events in each group, but none altered the patient's postoperative clinical course. Eckardt scores, used to assess success of the surgery, were 82% for POEM patients and 66% for LHM patients after 6 months. The outcomes for POEM and LHM in our early experience are similar to those reported in the literature for high-volume centers managing achalasia. PMID:28966450

Achalasia is a rare disorder that has several treatment options. The gold standard of treatment is a surgical myotomy called a laparoscopic Heller myotomy (LHM). More recently, an endoscopic myotomy has become an option as well, called per-oral endoscopic myotomy (POEM). An achalasia registry was queried for patients undergoing either LHM or POEM at Baylor University Medical Center at Dallas. Patient demographics, preoperative and postoperative data points, and Eckardt scores were collected. The patients were further stratified into their follow-up intervals, immediate postoperative and long-term follow-up, to assess surgical success. A subset analysis was done for success of treatment for patients who had redo surgery versus those undergoing the procedure for the first time. There were 12 patients in the POEM group and 11 patients in the LHM group. Both groups demonstrated mean lower esophageal sphincter pressures with failure to relax. Procedure length and hospital length of stay were similar between the two groups. There were three adverse events in each group, but none altered the patient's postoperative clinical course. Eckardt scores, used to assess success of the surgery, were 82% for POEM patients and 66% for LHM patients after 6 months. The outcomes for POEM and LHM in our early experience are similar to those reported in the literature for high-volume centers managing achalasia.

Despite many publications reporting on the increased hospital cost of robotic-assisted surgery (RAS) compared to direct manual laparoscopic surgery (DMLS) and open surgery (OS), the reported health economic studies lack details on clinical outcome, precluding valid health technology assessment (HTA). The present prospective study reports total cost analysis on 699 patients undergoing general surgical, gynecological and thoracic operations between 2011 and 2014 in the Italian Public Health Service, during which period eight major teaching hospitals treated the patients. The study compared total healthcare costs of RAS, DMLS and OS based on prospectively collected data on patient outcome in addition to healthcare costs incurred by the three approaches. The cost of RAS operations was significantly higher than that of OS and DMLS for both gynecological and thoracic operations (p < 0.001). The study showed no significant difference in total costs between OS and DMLS. Total costs of general surgery RAS were significantly higher than those of OS (p < 0.001), but not against DMLS general surgery. Indirect costs were significantly lower in RAS compared to both DMLS general surgery and OS gynecological surgery due to the shorter length of hospital stay of RAS approach (p < 0.001). Additionally, in all specialties compared to OS, patients treated by RAS experienced a quicker recovery and significantly less pain during the hospitalization and after discharge. The present HTA while confirming higher total healthcare costs for RAS operations identified significant clinical benefits which may justify the increased expenditure incurred by this approach.

In this article, we report the current surgical approach to gallbladder disease at a major referral hospital in rural Guatemala. Complications in a cohort of patients undergoing open versus laparoscopic cholecystectomy were catalogued. We reviewed cholecystectomies performed by surgeons at the Hospital Nacional de San Benito in El Peten, Guatemala, after the adoption of the laparoscopic approach. Laparoscopic cholecystectomies (LCs) between 2014 and 2015 (n = 42) were reviewed and matched by 58 randomly selected open cholecystectomies (OCs) during the same period. Patient demographics were similar in the LC and OC groups. Of the 63 patients who had elective surgery, 43 (68%) underwent OC. Conversion rate, hospital length of stay, and readmission rate were 4%, 4.8 days, and 5%, respectively. Complications were similar between groups. Despite the low number of LCs, their complications were not different from that of OCs. During the study period, a large number of cholecystectomies continued to be open, even in the elective setting. Published by Elsevier Inc.

The phase II randomized controlled trial aimed to compare the outcomes of robot-assisted surgery with those of laparoscopic surgery in the patients with rectal cancer. The feasibility of robot-assisted surgery over laparoscopic surgery for rectal cancer has not been established yet. Between February 21, 2012 and March 11, 2015, patients with rectal cancer (cT1-3NxM0) were enrolled. Patients were randomized 1:1 to either robot-assisted or laparoscopic surgery, and stratified per sex and administration of preoperative chemoradiotherapy. The primary outcome was the quality of total mesorectal excision (TME) specimen. Secondary outcomes were the circumferential and distal resection margins, the number of harvested lymph nodes, morbidity, bowel function recovery, and quality of life. A total of 163 patients were randomly assigned to the robot-assisted (n = 81) and laparoscopic (n = 82) surgery groups, and 139 patients were eligible for the analyses (73 vs 66, respectively). One patient (1.2%) in the robot-assisted group was converted to open surgery. The TME quality did not differ between the robot-assisted and laparoscopic groups (80.3% vs 78.1% complete TME, respectively; 18.2% vs 21.9% nearly complete TME, respectively; P = 0.599). The resection margins, number of harvested lymph nodes, morbidity, and bowel function recovery also were not significantly different. On analyzing quality of life, scores of the European Organization for Research and Treatment of Cancer Quality of Life (EORTC QLQ C30) and EORTC QLQ CR38 were similar in the 2 groups, but in the EORTC QLQ CR 38 questionnaire, sexual function 12 months postoperatively was better in the robot-assisted group than in the laparoscopic group (P = 0.03). Robot-assisted surgery in rectal cancer showed TME quality comparable with that of laparoscopic surgery, and it demonstrated similar postoperative morbidity, bowel function recovery, and quality of life.

There is increasing patient and surgeon interest in robotic-assisted surgery, particularly with the proliferation of da Vinci surgical systems (Intuitive Surgical, Sunnyvale, CA, USA) throughout the world. There is much debate over the usefulness and cost-effectiveness of these systems. The currently available robotic surgical technology is described. Published data relating to the da Vinci system are reviewed and the current status of surgical robotics within Australia and New Zealand is assessed. The first da Vinci system in Australia and New Zealand was installed in 2003. Four systems had been installed by 2006 and seven systems are currently in use. Most of these are based in private hospitals. Technical advantages of this system include 3-D vision, enhanced dexterity and improved ergonomics when compared with standard laparoscopic surgery. Most procedures currently carried out are urological, with cardiac, gynaecological and general surgeons also using this system. The number of patients undergoing robotic-assisted surgery in Australia and New Zealand has increased fivefold in the past 4 years. The most common procedure carried out is robotic-assisted laparoscopic radical prostatectomy. Published data suggest that robotic-assisted surgery is feasible and safe although the installation and recurring costs remain high. There is increasing acceptance of robotic-assisted surgery, especially for urological procedures. The da Vinci surgical system is becoming more widely available in Australia and New Zealand. Other surgical specialties will probably use this technology. Significant costs are associated with robotic technology and it is not yet widely available to public patients.

Pneumoperitoneum deteriorates intratidal respiratory system mechanics: an observational study in lung-healthy patients.

Wirth, Steffen; Biesemann, Andreas; Spaeth, Johannes; Schumann, Stefan

Pneumoperitoneum during laparoscopic surgery leads to atelectasis and impairment of oxygenation. Positive end-expiratory pressure (PEEP) is supposed to counteract atelectasis. We hypothesized that the derecruiting effects of pneumoperitoneum would deteriorate the intratidal compliance profile in patients undergoing laparoscopic surgery. In 30 adult patients scheduled for surgery with pneumoperitoneum, respiratory variables were measured during mechanical ventilation. We calculated the dynamic compliance of the respiratory system (C RS ) and the intratidal volume-dependent C RS curve using the gliding-SLICE method. The C RS curve was then classified in terms of indicating intratidal recruitment/derecruitment (increasing profile) and overdistension (decreasing profile). During the surgical interventions, the PEEP level was maintained nearly constant at 7 cm H 2 O. Data are expressed as mean [confidence interval]. Baseline C RS was 60 [54-67] mL cm H 2 O -1 . Application of pneumoperitoneum decreased C RS to 40 [37-43] mL cm H 2 O -1 which partially recovered to 54 [50-59] mL cm H 2 O -1 (P < 0.001) after removal but remained below the value measured before pneumoperitoneum (P < 0.001). Baseline compliance profiles indicated intratidal recruitment/derecruitment in 48 % patients. After induction of pneumoperitoneum, intratidal recruitment/derecruitment was indicated in 93 % patients (P < 0.01), and after removal intratidal recruitment/derecruitment was indicated in 59 % patients. Compliance profiles showing overdistension were not observed. Analyses of the intratidal compliance profiles reveal that pneumoperitoneum during laparoscopic surgery causes intratidal recruitment/derecruitment which partly persists after its removal. The analysis of the intratidal volume-dependent C RS profiles could be used to guide intraoperative PEEP adjustments during elevated intraabdominal pressure.

To evaluate the impact of a laparoscopic resection on postoperative mortality after colorectal cancer surgery. The question whether laparoscopic resection (LR) compared with open surgery [open resection (OR)] for colorectal cancer influences the risk of postoperative mortality remains unresolved. Several meta-analyses showed a trend but failed to reach statistical significance. The exclusion of high-risk patients and insufficient power might be responsible for that. We analyzed the influence of LR on postoperative mortality in a risk-stratified comparison and secondly, we studied the effect of LR on postoperative morbidity. Data from the Dutch Surgical Colorectal Audit (2010-2013) were used. Homogenous subgroups of patients were defined on the basis of factors influencing the choice of surgical approach and risk factors for postoperative mortality. Crude mortality rates were compared between LR and OR. The influence of LR on postoperative complications was evaluated using both univariable and multivariable analyses. In patients undergoing elective surgery for nonlocally advanced, nonmetastasized colon cancer, LR was associated with a significant lower risk of postoperative mortality than OR in 20/22 subgroups. LR was independently associated with a lower risk of cardiac (odds ratio: 0.73, 95% confidence interval: 0.66-0.82) and respiratory (odds ratio: 0.73, 95% confidence interval: 0.64-0.84) complications. LR reduces the risk of postoperative mortality compared with OR in elective setting in patients with nonlocally advanced, nonmetastasized colorectal cancer. Especially elderly frail patients seem to benefit because of reduced cardiopulmonary complications. These findings support widespread implementation of LR for colorectal cancer also in patients at high operative risk.

Chronic groin pain is the most frequent long-term complication after inguinal hernia repair affecting up to 34 per cent of patients. Traditional surgical management includes groin exploration, mesh removal, and neurectomy. We evaluate outcomes of a combined laparoscopic and open approach to chronic pain after inguinal herniorrhaphy. All patients undergoing surgical exploration for chronic pain after inguinal herniorrhaphy were analyzed. In most, the operation consisted of mesh removal (open or laparoscopic), neurectomy, and placement of mesh in the opposite location of the first mesh (laparoscopic if the first was open and vice-versa). Main outcome measures included pain status, numbness, and hernia recurrence. Twenty-one patients (16 male and 5 female) with a mean age of 41 years (22-51 years) underwent surgical treatment for unilateral (n = 18) or bilateral (n = 3) groin pain. Percutaneous nerve block was unsuccessful in all patients. Four had previous surgery for pain. There were no complications. With a minimum of 6 weeks follow-up, 20 of 21 patients reported significant improvement or resolution of symptoms. A combined laparoscopic and open approach for postherniorrhaphy groin pain results in excellent patient satisfaction with minimal morbidity. It may be the preferred technique for the definitive management of chronic neuralgia after hernia repair.

[Perforated peptic ulcer closure: laparoscopic or open?

Alekberzade, A V; Krylov, N N; Rustamov, E A; Badalov, D A; Popovtsev, M A

To compare laparoscopic and open closure of perforated peptic ulcer (PPU). The study included 153 patients who underwent PPU suturing. 78 patients underwent laparoscopic closure (laparoscopic group) and open suturing via upper midline laparotomy was performed in 75 cases (open group). Surgery time, postoperative pain severity, time of analgesics intake, postoperative complications, hospital-stay and and cosmetic effect were compared. Laparoscopic PPU closure may be effective and accessible in experienced endoscopic surgeon. It significantly reduces postoperative pain severity, need for analgesics, incidence of postoperative complications and provides excellent cosmetic effect. However, there is greater time of surgery compared with open intervention. There were no significant differences in hspital-stay between groups. Laparoscopic PPU suturing can be considered a good alternative to open surgery. Further researches are needed for standardization, assessment of safety, real advantages and disadvantages of laparoscopic technique.

One of the most controversial discussions on laparoscopic surgery deals with the question of whether to apply this technique to malignant disease and specifically to rectal cancer. The four major issues are the adequacy of oncologic resection, recurrence rates and patterns, long-term survival and quality of life. There is evidence, from nonrandomized studies, suggesting that margins of excision and lymph node harvest achieved laparoscopically reached comparable results to those known from conventional open resection. Our own experience of laparoscopic surgery on rectal cancer is based on 52 patients treated with curative intent. Focusing on the postoperative long-term run, we gained the following results: The median age of patients was 66.7 years and ranged from 42-88. Anastomotic leakage was seen in 6.1% of cases. In a median follow-up of 48 months (36-136), we reached an overall 3-year survival rate of 93% and a 5-year survival rate of 62%. Local recurrence was 1.9%, distant metastasis occurred in 11.5% of cases. We saw no port-site metastasis. To evaluate functional results following laparoscopic surgery a matched pair analysis was carried out. Matching of patients after laparoscopic and conventional open surgery was performed according to sex, age, type of resection, time period of surgery, and stage of disease classified by UICC. Regarding bladder and sexual dysfunction, using the EORTC QLQ CR38 score we found no statistical significant difference between the examined groups. As far as can be seen, laparoscopic surgery in rectal carcinoma may achieve the same or, in selected patients, even better results than open surgery. However, at present no published study has shown much evidence. Many more studies are necessary to define the place of laparoscopic technique in rectal cancer surgery, regarding appropriate selection of patients and evaluating adjuvant or neoadjuvant treatment in combination with the laparoscopic approach.

Introduction The benefits of antireflux surgery are well established. Laparoscopic techniques have been shown to be generally safe and effective. The aim of this paper was to review the subject of pain following laparoscopic antireflux surgery. Methods A systematic review of the literature was conducted using the PubMed database to identify all studies reporting pain after laparoscopic antireflux surgery. Publications were included for the main analysis if they contained at least 30 patients. Operations in children, Collis gastroplasty procedures, endoluminal fundoplication and surgery for paraoesophageal hernias were excluded. The frequency of postoperative pain was calculated and the causes/management were reviewed. An algorithm for the investigation of patients with pain following laparoscopic fundoplication was constructed. Results A total of 17 studies were included in the main analysis. Abdominal pain and chest pain following laparoscopic fundoplication were reported in 24.0% and 19.5% of patients respectively. Pain was mild or moderate in the majority and severe in 4%. Frequency of pain was not associated with operation type. The authors include their experience in managing patients with persistent, severe epigastric pain following laparoscopic anterior fundoplication. Conclusions Pain following laparoscopic antireflux surgery occurs in over 20% of patients. Some have an obvious complication or a diagnosis made through routine investigation. Most have mild to moderate pain with minimal effect on quality of life. In a smaller proportion of patients, pain is severe, persistent and can be disabling. In this group, diagnosis is more difficult but systematic investigation can be rewarding, and can enable appropriate and successful treatment. PMID:24780664

To compare the effects of premedication with intravenous paracetamol versus ketorolac, in decreasing intraoperative anaesthetic and postoperative opioid analgesics requirements in patients undergoing laparoscopic cholecystectomy. An experimental, prospective, comparative, double blind, and randomised clinical trial was conducted to determine intraoperative opioid requirements, and pain and analgesic requirements in the postoperative period in 100 healthy patients undergoing laparoscopic cholecystectomy. They were randomised into 2 groups: Group 1: pre-medicated with paracetamol 1g, and Group 2: with ketorolac 30mg (both administered intravenously 30minutes prior to surgery). There were no statistically significant differences between groups as regards intraoperative remifentanil use (Group 1: 0.0739±0.016μg/kg/min, Group 2: 0.0741±0.018μg/kg/min). The number of patients in Group 2 that had values of VAS>4 points (22.4%) was lower than in Group 1 (28.6%), but with no statistically significant difference. Of the patients who needed postoperative opioid rescue, most required a single rescue and application of analgesics during hospitalisation, that prevailed between 3 and 12hours, without any significant differences between groups. No adverse effects were observed in the study sample. Paracetamol 1g IV given preoperatively decreased anaesthetic requirements and the need for postoperative analgesics similar to the preoperative administration of ketorolac 30mg IV.

Panait, Lucian; Shetty, Shohan; Shewokis, Patricia A; Sanchez, Juan A

2014-03-01

Identifying the set of skills that can transfer from laparoscopic to robotic surgery is an important consideration in designing optimal training curricula. We tested the degree to which laparoscopic skills transfer to a robotic platform. Fourteen medical students and 14 surgery residents with no previous robotic but varying degrees of laparoscopic experience were studied. Three fundamentals of laparoscopic surgery tasks were used on the laparoscopic box trainer and then the da Vinci robot: peg transfer (PT), circle cutting (CC), and intracorporeal suturing (IS). A questionnaire was administered for assessing subjects' comfort level with each task. Standard fundamentals of laparoscopic surgery scoring metric were used and higher scores indicate a superior performance. For the group, PT and CC scores were similar between robotic and laparoscopic modalities (90 versus 90 and 52 versus 47; P > 0.05). However, for the advanced IS task, robotic-IS scores were significantly higher than laparoscopic-IS (80 versus 53; P < 0.001). Subgroup analysis of senior residents revealed a lower robotic-PT score when compared with laparoscopic-PT (92 versus 105; P < 0.05). Scores for CC and IS were similar in this subgroup (64 ± 9 versus 69 ± 15 and 95 ± 3 versus 92 ± 10; P > 0.05). The robot was favored over laparoscopy for all drills (PT, 66.7%; CC, 88.9%; IS, 94.4%). For simple tasks, participants with preexisting skills perform worse with the robot. However, with increasing task difficulty, robotic performance is equal or better than laparoscopy. Laparoscopic skills appear to readily transfer to a robotic platform, and difficult tasks such as IS are actually enhanced, even in subjects naive to the technology. Copyright © 2014 Elsevier Inc.

Introduction Conventional laparoscopic procedures have been used for splenic diseases and concomitant gallbladder stones, frequently in patients with hereditary spherocytosis since 1990’s. The aim of this study is to evaluate the feasibility of single-site surgery with conventional instruments in combined procedures. Presentation of case series Six consecutive patients who scheduled for combined cholecystectomy and splenectomy because of hereditary spherocytosis or autoimmune hemolytic anemia were included this study. Both procedures were performed via trans-umbilical single-site multiport approach using conventional instruments. All procedures completed successfully without conversion to open surgery or conventional laparoscopic surgery. An additional trocar was required for only one patient. The mean operation time was 190 min (150–275 min). The mean blood loss was 185 ml (70–300 ml). Median postoperative hospital stay was two days. No perioperative mortality or major complications occurred in our series. Recurrent anemia, hernia formation or wound infection was not observed during the follow-up period. Discussion Nowadays, publications are arising about laparoscopic or single site surgery for combined diseases. Surgery for combined diseases has some difficulties owing to the placement of organs and position of the patient during laparoscopic surgery. Single site laparoscopic surgery has been proposed to have better cosmetic outcome, less postoperative pain, greater patient satisfaction and faster recovery compared to standard laparoscopy. Conclusion We consider that single-site multiport laparoscopic approach for combined splenectomy and cholecystectomy is a safe and feasible technique, after gaining enough experience on single site surgery.

2013-03-01

Single-port laparoscopic surgery has attracted attention in the field of minimally invasive colorectal surgery. We hypothesized that an experienced laparoscopic surgeon could perform single-port surgery for colon cancer eligible for conventional laparoscopic anterior resection. Our aim was to analyze our initial experience and immediate surgical outcomes of single-port anterior resection. A total of 37 consecutive patients with presumed sigmoid colonic cancer underwent single-port anterior resection with standard laparoscopic instruments between May 2009 and June 2010. Each operation was performed by one of two experienced colorectal surgeons. A cohort of patients who had undergone conventional laparoscopic surgery (CLS) for the same duration a year earlier (August 2007 to September 2008) was used as a historical control. Patient demographics and perioperative outcomes were analyzed and compared with those of CLS. There were no significant differences in mean estimated blood loss, mean length of the resection margin, or morbidity between the two groups, but operative time for the single-port group was significantly shorter (118 ± 41 vs. 140 ± 42 min; p = 0.017). Single-port laparoscopic surgery was successfully performed in 78.4% (29/37) of the patients treated in 2010, and CLS was successfully completed in all of the patients treated the previous year (p = 0.000). The main causes of single-port surgery failure were adhesion and tumor location. Single-port anterior resection is a feasible and safe procedure with immediate outcomes comparable to those of conventional laparoscopy. Further studies are required to determine the feasibility of single-port surgery for colonic tumors outside the sigmoid colon and the long-term outcome.

THE OBJECTIVE OF THIS STUDY: was to analyze data on laparoscopic surgery for malignant diseases of the colon, rectum, and anus in Lithuania during the period of January 1, 2005, to February 15, 2008. During the above-mentioned period in Lithuania, 130 laparoscopic surgeries for malignancies of colon, rectum, and anus were performed in seven different hospitals. There were 73 males and 57 females with a mean age of 68 years (range, 35-85 years). Laparoscopic procedures were attempted in 140 cases. Out of them, 130 were completed laparoscopically; 10 operations were converted to open, and conversion rate was 7.1%. Twenty-seven (20.8%) patients had stage I, 45 (34.6%) stage II, 45 (34.6%) stage III, and 13 (10%) stage IV disease. Ninety-two (70.8%) patients underwent straight laparoscopic surgery and 38 (29.2%) - hand-assisted laparoscopic surgery. Time in surgery was from 50 to 365 min, with a mean of 183 min. During 130 operations, in 11 (8.5%) cases, blood vessels were ligated through specimen retrieval site. Out of 104 operations, where anastomosis was performed (23 abdominoperineal resections and 3 Hartmann's procedures), in 68 (65.4%) cases it was done laparoscopically and in 36 (34.6%) cases using conventional extracorporal suturing. Hospital stay ranged from 7 to 59 days, with a mean of 12 days. One (0.8%) patient died. Postoperative complications occurred in 27 (20.8%) cases. Reoperation rate was 4.6% (6 cases). Complications were as follows: suture insufficiency (3 cases), eventration (3 cases), wound infection (7 cases), intraperitoneal abscess (1 case), abdominal wall phlegmon (1 case), intra-abdominal infiltrate (1 case), perineal hematoma (1 case), proctovaginal fistula (2 case), intraoperative bleeding from uterus (1 case), urinary retention (4 cases), cystitis (1 case), pneumonia (1 case), acute cardiovascular insufficiently (1 case). In histological specimens, 10 lymph nodes were found on the average (range, 2 to 27). Laparoscopic surgery for malignant diseases of the colon, rectum, and anus is dominating among laparoscopic surgeries for colorectum. Complication rate is similar to other authors. To evaluate disease relapse and outcomes, observation time is not sufficient yet.

Study Objectives: (a) To find out the actual incidence of complications during endoscopic surgeries. (b) Comparison of complication rate between an experienced laparoscopic surgeon (> 10 years of experience in endoscopic surgery) and a clinical assistant (> 3 years of experience in endoscopic surgery). (c) How to manage complications in endoscopic surgery. (d) Concrete suggestions to reduce the complication rate. Design: Retrospective study (Canadian Task Force classification ii-2). Setting: Tertiary gynecologic endoscopic unit. Patients: A total of 3204 cases of gynecologic endoscopic surgery out of which 2001 were laparoscopic and 1203 were hysteroscopic surgeries. Interventions: Laparoscopic and hysteroscopic gynecologic surgeries in indicated cases. Measurements and Main Results: The study was carried out between April 2003 and October 2007 at a referral center for endoscopic surgery. A total of 3204 cases of gynecologic endoscopic surgery were studied. There were five significant complications in laparoscopic surgeries and four significant complications in hysteroscopic surgeries seen in four years and six months. All the complications could be managed with no mortality. Conversion to laparotomy was needed in eight cases of laparoscopic surgeries and none in hysteroscopic surgeries. Conclusion: The risk of complication reduces with the experience in endoscopic surgery. However, the proper grooming of a novice in experienced hands, for a sufficient period of time, can minimize the complication rate in the initial learning phase. The complication may be utilized as a stepping-stone to overcome any given situation without panic, but with adequate safety. PMID:22442510

To investigate ureteral injury during gynecological laparoscopic surgeries. From January 1990 to December 2005, 12 868 gynecological laparoscopic surgeries were conducted in Peking Union Medical College Hospital with 12 ureteral injuries reported. The present study investigated several aspects, including surgical indications, uterine size, pelvic adhesion, operative procedures, symptoms, diagnostic time and methods, injury site and type, subsequent treatment, and prognosis. The incidence of ureteral injury was 0.093% (12/12 868) in all cases, 0.42% (11/2 586) in laparoscopic hysterectomy [laparoscopically assisted vaginal hysterectomy (LAVH) or total laparoscopic hysterectomy (TLH)], and 0.01% (1/10 282) in non-LAVH surgeries. Enlarged uterus, pelvic adhesion, and endometrosis were risk factors associated with ureteral injury. Only one injury was found intraoperatively while others were found postoperatively. The injury sites were at the pelvic brim (2 cases) or the lower part of ureter (10 cases). Patients were treated with ureteral stenting (effective in 2 cases) or laparotomy and open repair. Prognoses were favorable in most cases. Most laparoscopic ureteral injuries occur during laparoscopic hysterectomy. Further evaluation is required when ureteral injury is suspected, and surgical repair is the major treatment for ureteral injury.

Abstract Laparoscopic surgery has been widely accepted as a feasible and safe treatment modality in many cancers of the gastrointestinal tract. However, most guidelines on gallbladder cancer (GBC) regard laparoscopic surgery as a contraindication, even for early GBC. This study aims to evaluate and compare recent surgical outcomes of laparoscopic and open surgery for T1(a,b) GBC and to determine the optimal surgical strategy for T1 GBC. The study enrolled 197 patients with histopathologically proven T1 GBC and no history of other cancers who underwent surgery from 2000 to 2014 at 3 major tertiary referral hospitals with specialized biliary-pancreas pathologists and optimal pathologic handling protocols. Median follow-up was 56 months. The effects of depth of invasion and type of surgery on disease-specific survival and recurrence patterns were investigated. Of the 197 patients, 116 (58.9%) underwent simple cholecystectomy, including 31 (15.7%) who underwent open cholecystectomy and 85 (43.1%) laparoscopic cholecystectomy. The remaining 81 (41.1%) patients underwent extended cholecystectomy. Five-year disease-specific survival rates were similar in patients who underwent simple and extended cholecystectomy (96.7% vs 100%, P = 0.483), as well as being similar in patients in the simple cholecystectomy group who underwent open and laparoscopic cholecystectomy (100% vs 97.6%, P = 0.543). Type of surgery had no effect on recurrence patterns. Laparoscopic cholecystectomy for T1 gallbladder cancer can provide similar survival outcomes compared to open surgery. Considering less blood loss and shorter hospital stay with better cosmetic outcome, laparoscopic cholecystectomy can be justified as a standard treatment for T1b as well as T1a gallbladder cancer when done by well-experienced surgeons based on exact pathologic diagnosis.

Recently, nonopioid-based treatment modalities have been used to improve analgesia and decrease opioid-related side effects after surgery. Transversus abdominis plane (TAP) block and local infiltration of the surgical wound are commonly used multimodal analgesia techniques after abdominal surgery; however, few studies have compared the effectiveness of a TAP block with that of local infiltration of surgical wounds in patients who have undergone laparoscopic colorectal surgery. Sixty patients undergoing laparoscopic colorectal surgery participated in this prospective comparative study. All patients were allocated to 1 of 2 groups as follows: the TAP group or the infiltration group. Patients in the TAP group received bilateral TAP blocks at the end of the surgery. Patients in the infiltration group received local infiltration of anesthetics in the surgical wounds after closure of the peritoneum. All patients received postoperative analgesia with morphine as a patient-controlled analgesia. Opioid consumption and pain scores were recorded at 2, 6, 24, and 48 h after the operation. The characteristics of patients in the TAP group (n = 30) and local infiltration group (n = 29) were comparable. Pain scores while coughing and at rest were not different between the two groups. Postoperative morphine use was significantly reduced in the TAP group compared with that in the local infiltration group at 2-6 h (2.9 ± 1.9 mg versus 4.5 ± 3.2 mg, P = 0.02), 6-24 h (5.5 ± 3.3 mg versus 10.2 ± 8.4 mg, P = 0.00), the first 24 h (16.6 ± 6.6 mg versus 24.0 ± 9.7 mg), and 48 h (23.6 ± 8.2 mg versus 31.8 ± 12.5 mg, P = 0.00). No differences in rescue analgesic use or side effects were noted between the groups. Compared with local anesthetic infiltration, bilateral TAP blocks decreased the cumulative morphine use at 24 h and 48 h postoperatively in patients who had undergone laparoscopic colorectal surgery.

We report our experience on 127 kidney surgeries with the da Vinci surgical system and show the feasibility of a robotics application in a variety of kidney surgeries by both a laparoscopically-trained and a laparoscopically-naïve surgeon. Clinical data of patients who underwent kidney surgery with the da Vinci surgical system from September 2006 to April 2009 were reviewed. Data acquired from medical records included patient demographics, operative time, estimated blood loss (EBL), incidence of intraoperative complication, duration of hospital stay, blood transfusion rate, oncological outcomes, and follow-up results. One-hundred twenty-seven kidney surgeries have been conducted with the da Vinci surgical system at our institution. Three urologists--1 with formal endourology training, 1 with laparoscopic experience, and 1 laparoscopically naïve--have used it for a variety of procedures involving the kidney. The cases include 65 partial nephrectomies (RPN), 38 radical nephrectomies (RRN), and 24 nephroureterectomies with bladder cuff (RNU). Results on operative time, EBL, incidence of intraoperative injury, duration of hospital stay, and blood transfusion rate are comparable with contemporary studies. Robotics application in kidney surgery is a viable option for various procedures. Our experience shows it can be safely and effectively conducted by both laparoscopically-trained and laparoscopically-naïve surgeons once they are accustomed to the robotics system.

Several experienced practitioners of open surgery with limited or no laparoscopic background have adopted robot-assisted laparoscopic radical prostatectomy (RLRP) as an alternative to open radical prostatectomy (RRP), demonstrating outcomes comparable to those in large RRP and laparoscopic prostatectomy series. Thus, the significance of prior laparoscopic skills seems unclear. The learning curve, with respect to operative time and complications, in the hands of a devoted laparoscopic surgeon has not been critically assessed. We evaluated the learning curve of a highly experienced laparoscopic surgeon in achieving expertise with RLRP. We prospectively evaluated 150 consecutive patients undergoing RLRP by a single surgeon between March 2003 and September 2005. The first 25 cases were performed with the assistance of a surgeon experienced in open RRP. Data were compared for the first, second, and third groups of 50 cases. Demographic data were similar for the three groups. Urinary and sexual function data were evaluated subjectively and objectively using the RAND-36v2 Survey and the UCLA PCI preoperatively and at 3, 6, and 12 months postoperatively. The mean operative time, blood loss, and conversion rate decreased significantly with increasing experience. All open conversions occurred during the first 25 cases. Intraoperative and postoperative complication rates were similar among groups. Although the differences were not significant, urinary and sexual function recovery improved with experience. The RLRP learning curve for a fellowship-trained laparoscopic surgeon seems to be similar to that of laparoscopically naive yet experienced practitioners of open RRP. The RLRP is safe and reproducible and even during the learning curve can produce results similar to those reported in large RRP series. The importance of assistance by an experienced open RRP surgeon during the learning curve cannot be overemphasized.

Laparoscopic colectomy has been shown to be safe, oncologically comparable, and clinically beneficial over open colectomy for colon cancer, but utilization remains low. Objectives To evaluate the cost of laparoscopic colectomy vs open colectomy for colon cancer. The authors conducted a retrospective claims data analysis using the 2012 and 2013 Truven Health Analytics MarketScan Commercial Claims and Encounter Database. The denominator population consisted of individuals who had commercial insurance coverage in all months of 2012 and >1 month in 2013 and pharmacy coverage throughout eligibility. The study population included individuals aged 18-64 years who were identified with colon cancer in 2013 and underwent an elective inpatient open colectomy or laparoscopic colectomy between January and November 2013. The cost and re-admission rate of open vs laparoscopic colectomy were compared after risk, adjusting for comorbidities, demographics, and geographic region. During the study period, 1299 elective inpatient colon cancer colectomies were performed (open, n = 558; laparoscopic, n = 741). After risk adjustment, the laparoscopic vs open group was shown to have lower re-admission rates (6.61 and 10.93 per 100 cases, respectively, p = .0165), lower average re-admission costs ($1676 and $3151, respectively, p = .0309), and lower 30-day post-discharge healthcare utilization costs ($4842 and $7121, respectively, p = .0047). Average allowed cost for the combined inpatient and 30-day post-discharge period was lower for laparoscopic vs open colectomy cases ($36,395 and $44,226, respectively, p < .001). The cost of laparoscopic colectomy was found to be statistically significantly less than that of open colectomy in patients undergoing elective surgery for colon cancer.

Background and Objectives: Single-incision laparoscopic surgery is gaining popularity among minimally invasive surgeons and is now being applied to a broad number of surgical procedures. Although this technique uses only 1 port, the diameter of the incision is larger than in standard laparoscopic surgery. The long-term incidence of port-site hernias after single-incision laparoscopic surgery has yet to be determined. Methods: All patients who underwent a single-incision laparoscopic surgical procedure from May 2008 through May 2009 were included in the study. Single-incision laparoscopic surgical operations were performed either by a multiport technique or with a 3-trocar single-incision laparoscopic surgery port. The patients were seen at 30 to 36 months' follow-up, at which time they were examined for any evidence of port-site incisional hernia. Patients found to have hernias on clinical examination underwent repairs with mesh. Results: A total of 211 patients met the criteria for inclusion in the study. The types of operations included were cholecystectomy, appendectomy, sleeve gastrectomy, gastric banding, Nissen fundoplication, colectomy, and gastrojejunostomy. We found a port-site hernia rate of 2.9% at 30 to 36 months' follow-up. Conclusion: Port-site incisional hernia after single-incision laparoscopic surgical procedures remains a major setback for patients. The true incidence remains largely unknown because most patients are asymptomatic and therefore do not seek surgical aid. PMID:24960483

To compare cosmetic satisfaction with laparoendoscopic single-site surgery (LESS) compared with multi-port surgery. Randomized controlled trial (Canadian Task Force classification I). University hospital. Twenty women who underwent laparoscopically-assisted vaginal hysterectomy (LAVH) via LESS or multi-port surgery. Laparoendoscopic single-site surgery or multi-port surgery. Cosmetic satisfaction was assessed using the Body Image Questionnaire at baseline and at 1, 4, and 24 weeks after surgery. Of the 20 LESS procedures, 1 was converted to multi-port surgery because of severe adhesions, and 1 woman assigned to undergo multi-port surgery was lost to follow-up. The 2 surgery groups did not differ in clinical demographic data and surgical results or postoperative pain scores at 12, 24, and 36 hours. Compared with the multi-port group, the LESS group reported significantly higher cosmetic satisfaction at 1, 4, and 24 weeks after surgery (p < .01). Compared with multi-port surgery, LESS is not only a feasible approach with comparable operative outcomes but also has an advantage insofar as cosmetic outcome. Copyright © 2013 AAGL.

Minimally invasive surgery in elderly patients with colorectal cancer remains controversial. The study aimed to compare the operative, postoperative, and oncologic outcomes of robotic (robotic colorectal resection surgery [RCRS]) versus laparoscopic colorectal resection surgery (LCRS) in elderly patients with colorectal cancer. Propensity score matching (PSM) was used to compare patients aged 70 years and more undergoing elective RCRS or LCRS for colorectal cancer between 2010 and 2017. Overall, 160 patients underwent elective curative LCRS (n = 102) or RCRS (n = 58) for colorectal cancer. Before PSM, the mean preoperative Charlson score and the tumor size were significantly lower in the robotic group. After matching, 43 RCRSs were compared with 43 LCRSs. The RCRS group showed longer operative times (300.6 versus 214.5 min, P = .03) compared with LCRS, but all other operative variables were comparable between the two groups. No differences were found for postoperative morbidity, mortality, time to flatus, return to regular diet, and length of hospital stay. R0 resection was obtained in 95.3% of procedures. The overall and disease-free survival rates at 1, 2, and 3 years were similar between RCRS and LCRS patients. The presence of more than one comorbidity before surgery was significantly associated with the incidence of postoperative complications. In patients aged 70 years or more, robotic colorectal surgery showed operative and oncologic outcomes similar to those obtained by laparoscopy, despite longer operative times. Randomized trials are awaited to reliably assess the clinical and oncological noninferiority and the costs/benefits ratio of robotic colorectal surgery in elderly populations.

The recently published long-term oncological results of the large multicentric randomized prospective trials, such as COST, COLOR, and UK MRC CLASICC, have diminished once more the initial skepticism from the mid '90s, regarding the safety of laparoscopic approach for colorectal cancer surgery. The actual incidence of port-site metastases (PMSs) in the laparoscopic surgery for colorectal cancer is just arround 1%, being statistically simmilar to the wound metastases after open colorectal surgery. We followed up a series of 122 laparoscopic-assisted resections for colorectal adenocarcinoma, 49 for rectal cancer and 73 for colon cancer. The operations were performed at the Center of Digestive Diseases and Liver Transplantation, Fundeni Clinical Institute, Bucharest, Romania, between 1st January 2002 and 31st december 2008. There was only one case of PMS (0.81%). A 83-year old man developed a recurrent parietal tumor on the site of extraction minilaparotomy, 4 months after laparoscopic-assisted right hemicolectomy for a Dukes C, poorly differentiated (G3) adenocarcinoma of the cecum. We have reviewed the scientific relevant literature regarding the incidence and multi-factor etiology of PMSs in the laparoscopic surgery for colorectal cancer as well as the methods suggested for prevention of parietal tumour dissemination to the trocar or wound sites. PMSs consecutive to laparoscopic surgery for colorectal cancer are no longer a big concern enough to contraindicate this beneficial surgery for oncological reasons. However, PMSs continue to represent a reality which must be taken into consideration by any laparoscopic surgeon. There are different prevention measures that should be applied for reducing the occurence of this possible complication.

Postoperative nausea and vomiting (PONV) occur frequently after laparoscopic bariatric surgery. The combination of haloperidol, dexamethasone, and ondansetron may reduce these undesirable events. The aim of this study was to evaluate the intensity of nausea and pain, the number of vomiting episodes, and morphine consumption in postoperative (PO) obese patients undergoing laparoscopic sleeve gastrectomy (LSG). A clinical, randomized, controlled, double-blind study conducted with 90 patients with body mass index ≥ 35 kg.cm-2. Patients were divided into three groups of 30 individuals to receive ondansetron 8 mg (Group O); ondansetron 8 mg and dexamethasone 8 mg (Group OD); and ondansetron 8 mg, dexamethasone 8 mg, and haloperidol 2 mg (Group HDO). We evaluated the intensity of nausea and pain using the verbal numeric scale, cumulative number of vomiting episodes, and morphine consumption in the period of 0-2, 2-12, 12-24, and 24-36 hours postoperatively. Nausea intensity was lower in Group HDO compared to Group O (p = 0.001), pain intensity was lower in Group HDO compared to Group O (p = 0.046), and morphine consumption was lower in Group HDO compared to Group O (p = 0.037). There was no difference between groups regarding the number of vomiting episodes (p = 0.052). The combination of haloperidol, ondansetron, and dexamethasone reduced nausea and pain intensity and morphine consumption in postoperative obese patients undergoing LSG.

Laparoscopy cholecystectomy for the surgical treatment of cholelithiasis has been considered the gold standard. The referred pain to the shoulder (omalgia) may be present to 63% of the patients and limits outpatient management. The study was to evaluate the usefulness of acetazolamide associated with ketorolac for reduction of the omalgia to minimally invasive treatment. We performed a clinical trial, randomized, double blind in patients undergoing laparoscopic cholecystectomy to assess the reduction of post-operative omalgia comparing ketorolac and ketorolaco+acetazolamida. 31 patients in each group were studied. The study group: 250 mg of acetazolamide before anesthetic induction and 30 mg of ketorolac in the immediate postoperative period. one tablet of placebo prior to the anesthetic induction and 30 mg of ketorolac in the immediate postoperative. The presence of omalgia was assessed using the analog visual scale. The variables recorded included: age, sex, flow of carbon dioxide intra-abdominal pressure, surgical time, urgent or elective surgery, omalgia, severity of pain evaluated by analog visual scale, addition analgesia. Both groups were homogeneous and statistical analysis showed no differences in the variables studied. The omalgia in the study group was presented at 9.67% and in the group control was the 58.06% (p < 0.001). 250 mg oral acetazolamide associated 30 mg of ketorolac reduces significantly the development of omalgia in patients undergoing laparoscopic cholecystectomy.

During positive pressure ventilation, gastric inflation and subsequent pulmonary aspiration can occur. Rapid sequence induction (RSI) technique is an age-old formula to prevent this. We adopted a novel approach of RSI for patients with high risk of aspiration and evaluated it further in patients undergoing laparoscopic surgeries. We believe that, in patients with risk of gastric insufflation and pulmonary aspiration, transnasal humidified rapid-insufflation ventilatory exchange can be useful in facilitating pre- and apnoeic oxygenation till tracheal isolation is achieved.

Disadvantages related to CO2 pneumoperitoneum have led to development of the abdominal wall retractor (AWR), a device designed to facilitate laparoscopic surgery without conventional pneumoperitoneum (15 mmHg CO2). We investigated the effects of the AWR on hemodynamics and gas exchange in humans. We also investigated whether the use of an AWR imposed extra technical difficulties for the surgeon. A pilot study revealed that cholecystectomy without low-pressure pneumoperitoneum was technically impossible. A prospective randomized controlled trial: Twenty patients undergoing laparoscopic cholecystectomy were randomly allocated into group 1: AWR with low-pressure pneumoperitoneum (5 mmHg), or group 2: conventional pneumoperitoneum (15 mmHg). Surgery using the AWR lasted longer, 72 +/- 16 min (mean +/- SD) vs 50 +/- 18 min compared with standard laparoscopic cholecystectomy. There were no differences between the groups with respect to hemodynamic parameters, although a small reduction of the cardiac output was observed using conventional pneumoperitoneum (from 3.9 +/- 0.7 to 3. 2 +/- 1.1 l/min) and an increase during AWR (from 4.2 +/- 0.9 to 5.2 +/- 1.5 l/min). Peak inspiratory pressures were significantly higher during conventional pneumoperitoneum compared to AWR. A slight decrease in pH accompanied by an increase in CO2 developed during pneumoperitoneum and during the use of the AWR. In both groups arterial PO2 decreased. The results indicate that the view was impaired during use of the AWR and therefore its use was difficult and time-consuming. Possible advantages of this devices' effects on hemodynamics and ventilatory parameters could not be confirmed in this study.

Background: Laparoscopy is one of the most common surgical procedures and is the procedure of choice for most of the elective abdominal surgeries performed preferably under endotracheal general anesthesia. Technical advances in the field of laparoscopy have helped to reduce surgical trauma and discomfort, reduce anesthetic requirement resulting in shortened hospital stay. Recently, regional anaesthetic techniques have been found beneficial, especially in patients at a high risk to receive general anesthesia. Herewith we present a case series of laparoscopic appendectomy in eight American Society of Anaesthesiologists (ASA) I and II patients performed under spinal-epidural anaesthesia. Methods: Eight ASA Grade I and II adult patients undergoing elective Laparoscopic appendectomy received Combined Spinal Epidural Anaesthesia. Spinal Anaesthesia was performed at L2-L3 interspace using 2 ml of 0.5% (10 mg) hyperbaric Bupivacaine mixed with 0.5ml (25 micrograms) of Fentanyl. Epidural catheter was inserted at T10-T11 interspace for inadequate spinal anaesthesia and postoperative pain relief. Perioperative events and operative difficulty were studied. Systemic drugs were administered if patients complained of shoulder pain, abdominal discomfort, nausea or hypotension. Results: Spinal anaesthesia was adequate for surgery with no operative difficulty in all the patients. Intraoperatively, two patients experienced right shoulder pain and received Fentanyl, one patient was given Midazolam for anxiety and two were given Ephedrine for hypotension. The postoperative period was uneventful. Conclusion: Spinal anaesthesia with Hyperbaric Bupivacaine and Fentanyl is adequate and safe for elective laparoscopic appendectomy in healthy patients but careful evaluation of the method is needed particularly in compromised cardio respiratory conditions.

The utilization of robotic platforms for general surgery procedures such as hernia repair is growing rapidly in the United States. A limited amount of data are available evaluating operative outcomes in comparison to standard laparoscopic surgery. We completed a retrospective review comparing robotic and laparoscopic ventral hernia repair to provide safety and outcomes data to help design a future prospective trial design. A retrospective review of 215 patients undergoing ventral hernia repair (142 robotic and 73 laparoscopic) was completed at two large academic centers. Primary outcome measure evaluated was recurrence. Secondary outcomes included incidence of primary fascial closure, and surgical site occurrences. Propensity for treatment match comparison demonstrated that robotic repair was associated with a decreased incidence of recurrence (2.1 versus 4.2%, p < 0.001) and surgical site occurrence (4.2 versus 18.8%, p < 0.001). This may be because robotic repair was associated with increased incidence of primary fascial closure (77.1 versus 66.7%, p < 0.01). Analysis of baseline patient populations showed that robotic repairs were completed on patients with lower body mass index (28.1 ± 3.6 versus 34.2 ± 6.4, p < 0.001) and fewer comorbidities. Our retrospective data show that robotic repair was associated with decreased recurrence and surgical site occurrence. However, the differences noted in the patient populations limit the interpretability of these results. As adoption of robotic ventral hernia repair increases, prospective trials need to be designed in order to investigate the efficacy, safety, and cost effectiveness of this evolving technique.

Perforated diverticulitis is a condition associated with substantial morbidity. Recently published reports suggest that laparoscopic lavage has fewer complications and shorter hospital stay. So far no randomised study has published any results. DILALA is a Scandinavian, randomised trial, comparing laparoscopic lavage (LL) to the traditional Hartmann's Procedure (HP). Primary endpoint is the number of re-operations within 12 months. Secondary endpoints consist of mortality, quality of life (QoL), re-admission, health economy assessment and permanent stoma. Patients are included when surgery is required. A laparoscopy is performed and if Hinchey grade III is diagnosed the patient is included and randomised 1:1, to either LL or HP. Patients undergoing LL receive > 3L of saline intraperitoneally, placement of pelvic drain and continued antibiotics. Follow-up is scheduled 6-12 weeks, 6 months and 12 months. A QoL-form is filled out on discharge, 6- and 12 months. Inclusion is set to 80 patients (40+40). HP is associated with a high rate of complication. Not only does the primary operation entail complications, but also subsequent surgery is associated with a high morbidity. Thus the combined risk of treatment for the patient is high. The aim of the DILALA trial is to evaluate if laparoscopic lavage is a safe, minimally invasive method for patients with perforated diverticulitis Hinchey grade III, resulting in fewer re-operations, decreased morbidity, mortality, costs and increased quality of life.

Report of our initial experience in laparoscopic hysterectomy by a solo surgeon using a robotic camera system with three-dimensional visualisation. This novel device (Einstein Vision®, B. Braun, Aesculap AG, Tuttlingen, Germany) (EV) was used for laparoscopic supracervical hysterectomy (LASH) performed by one surgeon. Demographic data, clinical and surgical parameters were evaluated. Our first 22 cases, performed between June and November 2012, were compared with a cohort of 22 age-matched controls who underwent two-dimensional LASH performed by the same surgeon with a second surgeon assisting. Compared to standard two-dimensional laparoscopic hysterectomy, there were no significant differences regarding duration of surgery, hospital stay, blood loss or incidence of complications. The number of trocars used was significantly higher in the control group (p <.0001). All hysterectomies in the treatment group were performed without assistance of a second physician. Robot-assisted solo surgery laparoscopic hysterectomy is a feasible and safe procedure. Duration of surgery, hospital stay, blood loss, and complication rates are comparable to a conventional laparoscopic hysterectomy.

Several recent studies have suggested that warming up prior to surgery may improve surgical performance. The purpose of this study was to investigate whether warming up prior to laparoscopic surgery improves surgical performance or reduces surgery duration. Between August 2011 and January 2012, a randomized controlled trial was conducted to compare two warm-up modalities to no warm-up. The study was conducted at a single site, with nine surgeons performing 72 laparoscopic cholecystectomies and 37 laparoscopic appendicectomies. Prior to surgery, surgeons were randomized to either laparoscopic trainer box warm-up, PlayStation 2 warm-up or no warm-up. The activity was performed within 30 min of surgery commencing. Patients provided informed consent for the surgery to be digitally recorded. Digital videodiscs (DVDs) were reviewed by an independent and blinded assessor. Data were collected on duration of surgery, level of training and perceived surgical difficulty. Surgical performance was graded using a validated scoring system. From the 109 operations performed, there were 75 usable DVDs. Overall, there were no statistical differences in the demographics of patients and surgeons in the three treatment groups, nor in the subset that had useable DVDs. There were no statistical differences in the duration of surgery or surgeon's perceived surgical difficulty. There was no statistical difference in surgical performance. This study suggests that warm-up prior to laparoscopic cholecystectomy or appendicectomy is not essential, acknowledging that there are several study limitations that preclude definitive conclusion. © 2012 The Authors.

The performance of most bariatric procedures within an Enhanced Recovery After Surgery program has resulted in significant advantages, including a reduction in the length of hospital stay to 2-3 days. However, some postoperative complications may appear after the patient has been discharged. The aim of this study was to investigate the efficacy of various acute-phase parameters determined 24 h after a laparoscopic sleeve gastrectomy for predicting staple line leak in the postoperative course. A prospective study of 208 morbidly obese patients undergoing laparoscopic sleeve gastrectomy as bariatric procedure between 2012 and 2015 was performed. Blood analysis was performed 24 h after surgery. Acute-phase parameters (C-reactive protein, procalcitonin, fibrinogen, and White Blood Cell count) were investigated. Staple line leak appeared in eight patients (3.8%). Using receiver operating characteristic analysis at 24 h postoperatively, a cutoff level of CRP at 9 mg/dL achieved 85% sensitivity and 90% specificity for predicting staple line leak, a cutoff level of procalcitonin at 0.85 ng/mL achieved 70% sensitivity and 90% specificity, and a cutoff level of fibrinogen at 600 mg/dL achieved 80% sensitivity and 87.5% specificity. An elevation of CRP > 9 mg/dL, procalcitonin > 0.85 ng/mL and fibrinogen > 600 mg/dL should alert the surgeon the possibility of occurrence of postoperative staple line leak.

Predicting patient dissatisfaction following laparoscopic Nissen fundoplication: an analysis of symptoms.

Nissen fundoplication is a well-established treatment for gastroesophageal reflux disease (GERD) with a high success rate and a long-lasting effect. However, the literature reports that a persistent, small group of patients is not fully satisfied with the outcome. Identifying this patient group preoperatively would prevent disappointment for both patients and surgeon. This has proven difficult since dissatisfaction was related to nondisease-related factors instead of typical symptoms of GERD or the objective findings of investigations. We studied our series of patients who underwent laparoscopic Nissen fundoplication to identify predictors of patient dissatisfaction and the impact of surgery on individual symptoms. All consecutive private patients undergoing Nissen fundoplication were asked to complete a preoperative and postoperative questionnaire concerning symptoms, medication use, and satisfaction. Demographics, investigations, complications, and reinterventions were documented. A standard laparoscopic Nissen fundoplication was performed. Over an 11-year period 222 patients underwent surgery for GERD. The postoperative response rate to the questionnaire was 77.5 %, with dissatisfaction reported by 12.8 % of the patients. Of these dissatisfied patients, only 13.6 % had proven disease recurrence. Both satisfied and dissatisfied patients presented with an inconsistent pattern of symptoms. None of the preoperative symptoms and investigations or the patient's age and gender was predictive of postoperative dissatisfaction. Only postoperative heartburn, regurgitation, and bloating significantly correlated with patient dissatisfaction. Nissen fundoplication has a very high satisfaction rate overall. A small percentage of patients are not fully satisfied and dissatisfaction is associated with reported persistent symptoms and side effects of surgery rather than gender or preoperative symptom pattern, severity of esophagitis, or total 24 h esophageal acid exposure.

Although bariatric surgery is actually mainly performed laparoscopically, analgesic optimization continues being essential to reduce complications and to improve the patients' comfort. The aim of this study is to evaluate the postoperative pain after analgesia iv exclusively, or associated with epidural analgesia or port-sites infiltration with bupivacaine. A prospective randomized study of patients undergoing laparoscopic sleeve gastrectomy between 2012 and 2014 was performed. Patients were divided into three groups: Analgesia iv exclusively (Group 1), epidural analgesia + analgesia iv (Group 2) and port-sites infiltration + analgesia iv (Group 3). Pain was quantified by means of a Visual Analogic Scale, and morphine rescue needs were determined 24 h after surgery. A total of 147 were included. Groups were comparable in age, gender and BMI. There were no differences in operation time, complications, mortality or hospital stay between groups. Median pain 24 h after surgery was 5 in Group 1, 2.5 in Group 2 and 2 in Group 3 (P = 0.01), without statistically significant differences between Groups 2 and 3. In Group 1, morphine rescue was necessary in 16.3 % of the cases, 2 % in Group 2 and 2 % in Group 3 (P = 0.014), without statistically significant differences between Groups 2 and 3. Epidural analgesia and port-sites infiltration with bupivacaine, associated with analgesia iv, reduce the postoperative pain, when compared with analgesia iv exclusively.

With the advancement of laparoscopic devices and surgical technology, the era of minimal invasive surgery has progressed to reduced-port surgery, and finally to single-incision laparoscopic surgery (SILS). Several reports show successful application of SILS to various types of bariatric surgery. Oftentimes, this requires a skilled and experienced scopist to perform the procedure. To overcome the technical difficulties of single-incision Roux-en-Y gastric bypass, a manual scope holder was used instead of an assistant scopist, greatly stabilizing the field of view. This allows the surgery to be performed at any time without being influenced by the need of a highly experienced scopist. In this report, we describe in detail the world's first solo single-incision laparoscopic resectional Roux-en-Y gastric bypass.

[Therapy concepts for diffuse peritonitis: When laparoscopic lavage and when open abdomen?].

PubMed

2016-01-01

Secondary diffuse peritonitis still has a high morbidity and mortality even now; therefore, the various strategies and options for the different surgical therapies are undergoing an evidence-based review. Laparoscopic lavage without resection of the focus of sepsis for example is a profoundly different approach in the treatment of diffuse peritonitis from the damage control-based strategy of surgery with initial laparostomy and deferred anastomosis. The evidential data for minimally invasive therapy are comparatively well-reviewed for appendicitis, cholecystitis and ulcerated perforation of the stomach and duodenum. In contrast, the evidence for laparoscopy and minimally invasive surgery with lavage and deferred anastomosis or damage control in secondary peritonitis has improved but is still low and cannot yet be clearly recommended. This article presents an overview of the currently available therapeutic methods for diffuse peritonitis and a critical consideration of the evidence-based data. The key recommendation is that the decision to use a surgical procedure based on the currently available data depends more on the severity of the abdominal sepsis, the duration, the age of the patient and comorbidities than on the individual technique.

The purpose of this study was to introduce a new method for locating the renal artery during retroperitoneal laparoscopic renal surgery. The medial arcuate ligament (MAL) is a tendinous arch in the fascia under the diaphragm that arches across the psoas major muscle and is attached medially to the side of the first or the second lumbar vertebra. The renal artery arises at the level of the intervertebral disc between the L1 and L2 vertebrae. We evaluate the role of the MAL that serves as an anatomic landmark for locating the renal artery during retroperitoneal laparoscopic renal surgery. There is a reproducible consistent anatomic relationship between MAL and the renal artery in 210 cases of retroperitoneal laparoscopic renal surgery. Two main types of the MAL, the "narrow arch" and the "fascial band" types, can be observed. MAL can serve as an accurate and reproducible anatomic landmark for the identification of the renal artery during retroperitoneal laparoscopic renal surgery.

Colorectal resections are common surgical procedures all over the world. Laparoscopic colorectal surgery is technically feasible in a considerable amount of patients under elective conditions. Several short-term benefits of the laparoscopic approach to colorectal resection (less pain, less morbidity, improved reconvalescence and better quality of life) have been proposed. This review compares laparoscopic and conventional colorectal resection with regards to possible benefits of the laparoscopic method in the short-term postoperative period (up to 3 months post surgery). We searched MEDLINE, EMBASE, CancerLit, and the Cochrane Central Register of Controlled Trials for the years 1991 to 2004. We also handsearched the following journals from 1991 to 2004: British Journal of Surgery, Archives of Surgery, Annals of Surgery, Surgery, World Journal of Surgery, Disease of Colon and Rectum, Surgical Endoscopy, International Journal of Colorectal Disease, Langenbeck's Archives of Surgery, Der Chirurg, Zentralblatt für Chirurgie, Aktuelle Chirurgie/Viszeralchirurgie. Handsearch of abstracts from the following society meetings from 1991 to 2004: American College of Surgeons, American Society of Colorectal Surgeons, Royal Society of Surgeons, British Assocation of Coloproctology, Surgical Association of Endoscopic Surgeons, European Association of Endoscopic Surgeons, Asian Society of Endoscopic Surgeons. All randomised-controlled trial were included regardless of the language of publication. No- or pseudorandomised trials as well as studies that followed patient's preferences towards one of the two interventions were excluded, but listed separately. RCT presented as only an abstract were excluded. Results were extracted from papers by three observers independently on a predefined data sheet. Disagreements were solved by discussion. 'REVMAN 4.2' was used for statistical analysis. Mean differences (95% confidence intervals) were used for analysing continuous variables. If studies reported medians and ranges instead of means and standard deviations, we assumed the difference of medians to be equal to the difference of means. If no measure of dispersion was given, we tried to obtain these data from the authors or estimated SD as the mean or median. Data were pooled and rate differences as well as weighted mean differences with their 95% confidence intervals were calculated using random effects models. 25 RCT were included and analysed. Methodological quality of most of these trials was only moderate and perioperative treatment was very traditional in most studies. Operative time was longer in laparoscopic surgery, but intraoperative blood was less than in conventional surgery. Intensity of postoperative pain and duration of postoperative ileus was shorter after laparoscopic colorectal resection and pulmonary function was improved after a laparoscopic approach. Total morbidity and local (surgical) morbidity was decreased in the laparoscopic groups. General morbidity and mortality was not different between both groups. Until the 30th postoperative day, quality of life was better in laparoscopic patients. Postoperative hospital stay was less in laparoscopic patients. Under traditional perioperative treatment, laparoscopic colonic resections show clinically relevant advantages in selected patients. If the long-term oncological results of laparoscopic and conventional resection of colonic carcinoma show equivalent results, the laparoscopic approach should be preferred in patients suitable for this approach to colectomy.

In the last few years there have been increasing claims that robotic assisted laparoscopic radical prostatectomy decreases short-term morbidity in patients undergoing surgical treatment for prostate cancer. However, there is surprisingly little objective evidence to support this point, which is often used to market the procedure to patients. To address this issue we prospectively evaluated patients undergoing open and robotic assisted laparoscopic radical prostatectomy at baseline and weekly through the postoperative period using a validated questionnaire. A total of 162 men undergoing radical prostatectomy, including open radical prostatectomy in 120 and robotic assisted laparoscopic radical prostatectomy in 42, for clinically localized prostate cancer completed the SF-12, version 2 Physical and Mental Health Survey Acute Form preoperatively and each week postoperatively for 6 weeks. Physical and Mental Component Scores were calculated from the questionnaires at each time point. Comparisons between the 2 surgical approaches were made at each time point. No significant differences were seen between the open and robotic assisted laparoscopic radical prostatectomy groups with regard to patient age, clinical stage or preoperative prostate specific antigen. Mean surgical blood loss was significantly higher in the open group compared to that in the robotic assisted laparoscopic group. Physical Component Scores in the robotic assisted laparoscopic group were significantly higher than those in the open cohort beginning postoperative week 1 and extending through week 6. On statistical extrapolation Physical Component Scores returned to baseline between weeks 5 and 6 postoperatively in the robotic assisted laparoscopic group and between weeks 6 and 7 in the open group. Mental Component Score scores were not statistically different between the groups except preoperatively. This study helps prospectively define short-term health related quality of life in patients undergoing robotic assisted laparoscopic vs open radical prostatectomy. Higher physical scores were seen in the robotic assisted laparoscopic group than the open group beginning postoperative week 1 and continuing weekly throughout the 6-week study period. Physical Component Score scores returned to baseline sooner in the robotic assisted laparoscopic group than in the open group.

The increased visceral fat in patients with obesity can increase the technical difficulty of surgery. This study was performed to evaluate a preoperative 20-day very low-calorie diet for obesity before laparoscopic gastrectomy for gastric cancer. This prospective single-center study involved patients with obesity who were planning to undergo laparoscopic gastrectomy for gastric cancer. Obesity was defined according to the Japanese criteria: BMI ≥25 kg/m 2 or waist circumference ≥85 cm in men and ≥90 cm in women. The patients underwent a preoperative 20-day very low-calorie diet and received nutritional counseling. Weight loss, body composition, visceral fat mass, and operative outcomes were evaluated. Thirty-three patients were enrolled from September 2013 to August 2015. Their median age was 71 years, and 78.8% were men. Their median bodyweight and BMI were 72.3 kg (range, 53.8-82.5 kg) and 26.0 kg/m 2 (range, 23.5-31.0 kg/m 2 ), respectively. The patients achieved a mean weight loss of 4.5% (95% confidence interval [CI]: 3.8-5.1), corresponding to 3.2 kg (95%CI: 2.7-3.7 kg). Body fat mass was significantly decreased by a mean of 2.5 kg (95%CI: 1.9-3.1), whereas skeletal muscle mass was unaffected (mean: -0.20 kg [95%CI: -0.55-0.15]). The visceral fat mass reduction rate was high as 16.8% (range, 11.6%-22.0%). All patients underwent laparoscopic gastrectomy as planned. Severe postoperative morbidity (Clavien-Dindo grade ≥III) was seen in only one patient (3.0%). The preoperative 20-day very low-calorie diet weight loss program is promising for the treatment of obesity before laparoscopic gastrectomy for gastric cancer. © 2018 The Authors.

Vitamin D deficiency (VDD) is associated with obesity and metabolic syndrome (MS). After bariatric surgery (BS), high rates of VDD often persist and some patients are refractory to the resolution of comorbidities. The aim of the present study is to analyse the relationship between the levels of vitamin D and the persistence of MS components at 12 months after BS, according to the surgical technique used. We performed a retrospective study of 46 patients undergoing BS: 23 underwent laparoscopic Roux-en-Y gastric bypass (LRYGBP) and 23 laparoscopic sleeve gastrectomy (LSG). These patients had an average BMI of 45 kg/m 2 (34-63). Levels of vitamin D were classified as deficient (<20 ng/dl), insufficient (20-30 ng/dl) or normal (>30 ng/dl) and analysed in relation to the components of MS (high blood pressure (HBP), dyslipidaemia (DL) and type 2 diabetes mellitus (T2DM) preoperatively and 12 months after surgery. VDD was observed in 77% of the patients prior to surgery. There were no significant associations between predisposing factors and baseline vitamin D. After surgery, plasma levels of vitamin D increased in both groups, but only 18% of the patients achieved normal values. Both groups had achieved significant improvements in MS components. Thus, 63% of all the patients achieved complete resolution of HBP, 54% that of DL and 77% that of T2DM. Moreover, MS was present in 11% of the patients, compared to 63% at baseline, and the MS resolution rate was 83%, with no significant differences between LRYGBP and LSG. There is a relationship between VDD and persistence of MS, and particularly so with T2DM. VDD could represent a predictor of MS persistence at 12 months after surgery.

The role of laparoscopic surgery in the repair for peptic ulcer disease is unclear. The present study aimed to compare the safety and efficacy of laparoscopic versus open repair for peptic ulcer disease. Randomized controlled trials (RCTs) comparing laparoscopic versus open repair for peptic ulcer disease were identified from MEDLINE, EMBASE, Cochrane Central Register of Controlled Trials, and references of identified articles and relevant reviews. Primary outcomes were postoperative complications, mortality, and reoperation. Secondary outcomes were operative time, postoperative pain, postoperative hospital stay, nasogastric tube duration, and time to resume diet. Statistical analysis was carried out by Review Manage software. Five RCTs investigating a total of 549 patients, of whom, 279 received laparoscopic repair and 270 received open repair, were included in the final analysis. There were no significant differences between these two procedures in some primary outcomes including overal postoperative complication rate, mortality, and reoperation rate. Subcategory analysis of postoperative complications showed that laparoscopic repair had also similar rates of repair site leakage, intra-abdominal abscess, postoperative ileus, pneumonia, and urinary tract infection as open surgery, except of the lower surgical site infection rate (P < 0.05). In addition, there were also no significant differences between these two procedures in some second outcomes including operative time, postoperative hospital stay, and time to resume diet, but laparoscopic repair had shorter nasogastric tube duration (P < 0.05) and less postoperative pain (P < 0.05) than open surgery. Laparoscopic surgery is comparable with open surgery in the setting of repair for perforated peptic ulcer. The obvious advantages of laparoscopic surgery are the lower surgical site infection rate, shorter nasogastric tube duration and less postoperative pain. However, more higher quality studies should be undertaken to further assess the safety and efficacy of laparoscopic repair for peptic ulcer disease. Copyright © 2016 IJS Publishing Group Ltd.

To examine opioid prescribing patterns after general surgery procedures and to estimate an ideal number of pills to prescribe. Diversion of prescription opioids is a major contributor to the rising mortality from opioid overdoses. Data to inform surgeons on the optimal dose of opioids to prescribe after common general surgical procedures is lacking. We evaluated 642 patients undergoing 5 outpatient procedures: partial mastectomy (PM), partial mastectomy with sentinel lymph node biopsy (PM SLNB), laparoscopic cholecystectomy (LC), laparoscopic inguinal hernia repair (LIH), and open inguinal hernia repair (IH). Postoperative opioid prescriptions and refill data were tabulated. A phone survey was conducted to determine the number of opioid pills taken. There was a wide variation in the number of opioid pills prescribed to patients undergoing the same operation. The median number (and range) prescribed were: PM 20 (0-50), PM SLNB 20 (0-60), LC 30 (0-100), LIH 30 (15-70), and IH 30 (15-120). Only 28% of the prescribed pills were taken. This percentage varied by operation: PM 15%, PM SLNB 25%, LC 33%, LIH 15%, and IH 31%. Less than 2% of patients obtained refills.We identified the number of pills that would fully supply the opioid needs of 80% of patients undergoing each operation: PM 5, PM SLNB 10, LC 15, LIH 15, and IH 15. If this number were prescribed, the number of opioid initially prescribed would be 43% of the actual number prescribed. There is wide variability in opioid prescriptions for common general surgery procedures. In many cases excess pills are prescribed. Using our ideal number, surgeons can adequately treat postoperative pain and markedly decrease the number of opioids prescribed.

Laparoscopic surgery has become a widely performed surgery as it is one of the most common minimally invasive surgeries. Doctors perform the surgery by manipulating thin and long surgical instruments precisely with the assistance of laparoscopic video with limited field of view. The power control of the instruments' tip is especially very important, because excessive power may damage internal organs. The training of this surgical technique is mainly supervised by an expert in hands-on coaching program. However, it is difficult for the experts to spend sufficient time for coaching. Therefore, we aim to teach the expert's hand movements in laparoscopic surgery to trainees using VR-based simulator, which is equipped with a guidance force display device. To realize the system, we propose two haptic training approaches for transferring the expert's hand movements to the trainee. One is active training, and the other is passive training. The former approach shows the expert's movements only when the trainee makes large errors while the latter shows the expert's movements continuously. In this study, we validate the applicability of these approaches through tasks in VR laparoscopic surgery training simulator, and identify the differences between these approaches.

Since it's introduction, laparoscopic surgery represented a real revolution in clinical practice. The use of a new generation three-dimensional (3D) HD laparoscopic system can be considered a favorable "hybrid" made by combining two different elements: feasibility and diffusion of laparoscopy and improved quality of vision. In this study we report our clinical experience with use of three-dimensional (3D) HD vision system for laparoscopic surgery. Between 2013 and 2017 a prospective cohort study was conducted at the University Hospital of Palermo. We considered 163 patients underwent to laparoscopic three-dimensional (3D) HD surgery for various indications. This 3D-group was compared to a retrospective-prospective control group of patients who underwent the same surgical procedures. Considerating specific surgical procedures there is no significant difference in term of age and gender. The analysis of all the groups of diseases shows that the laparoscopic procedures performed with 3D technology have a shorter mean operative time than comparable 2D procedures when we consider surgery that require complex tasks. The use of 3D laparoscopic technology is an extraordinary innovation in clinical practice, but the instrumentation is still not widespread. Precisely for this reason the studies in literature are few and mainly limited to the evaluation of the surgical skills to the simulator. This study aims to evaluate the actual benefits of the 3D laparoscopic system integrating it in clinical practice. The three-dimensional view allows advanced performance in particular conditions, such as small and deep spaces and promotes performing complex surgical laparoscopic procedures.

Laparoscopic colectomy is safe and effective in the treatment of many colorectal diseases. However, the effect of increasing use of laparoscopy on overall health care utilization and costs, especially in the long term, has not been thoroughly investigated. To evaluate the effect of laparoscopic vs open colectomy on short- and long-term health care utilization and costs. Retrospective multivariate regression analysis of national health insurance claims data was used to evaluate health care utilization and costs up to 1 year following elective colectomy. Data were obtained from the Truven Health Analytics MarketScan Commercial Claims and Encounters database. Patients aged 18 to 64 years who underwent elective laparoscopic or open colectomy from January 1, 2010, through December 31, 2010, were included. Patients with complex diagnoses that require increased non-surgery-related health care utilization, including malignant neoplasm, inflammatory bowel disease, human immunodeficiency virus, transplantation, and pregnancy, were excluded. Of 25 481 patients who underwent colectomy, 4160 were included in the study. Healthcare utilization, including office, hospital outpatient, and emergency department visits and inpatient services 90 and 365 days after the index procedure; total health care costs; and estimated days off from work owing to health care utilization. Of 25 481 patients who underwent colectomy, 4160 were included in the study (laparoscopic, 45.6%; open, 54.4%). The mean (SD) net and total payments were lower for laparoscopy ($23 064 [$14 558] and $24 196 [$14 507] vs $29 753 [$21 421] and $31 606 [$23 586]). In the first 90 days after surgery, an open approach was significantly associated with a 1.26-fold increase in health care costs (estimated, $1715; 95% CI, $338-$2853), increased use of heath care services, and more estimated days off from work (2.78 days; 95% CI, 1.93-3.59). Similar trends were found in the full postoperative year, with an estimated 1.18-fold increase (95% CI, 1.04-1.35) in health care expenditures and an increase of 1.15 times (95% CI, 1.08-1.23) the number of health care utilization days compared with laparoscopy. Laparoscopic colectomy results in a significant reduction in health care costs and utilization in the short- and long-term postoperative periods.

Laparoscopic surgery is normally performed under general anesthesia, but regional techniques like thoracic epidural and lumbar spinal have been emerging and found beneficial. We performed a clinical case study of segmental thoracic spinal anaesthesia in a healthy patient. We selected an ASA grade I patient undergoing elective laparoscopic cholecystectomy and gave spinal anesthetic in T10-11 interspace using 1 ml of bupivacaine 5 mg ml -1 mixed with 0.5 ml of fentanyl 50 μg ml -1 . Other drugs were only given (systemically) to manage patient anxiety, pain, nausea, hypotension, or pruritus during or after surgery. The patient was reviewed 2 days postoperatively in ward. The thoracic spinal anesthetia was performed easily in the patient. Some discomfort which was readily treated with 1mg midazolam and 20 mg ketamine intravenously. There was no neurological deficit and hemodynamic parameters were in normal range intra and post-operatively and recovery was uneventful. We used a narrow gauze (26G) spinal needle which minimized the trauma to the patient and the chances of PDPH, which was more if 16 or 18G epidural needle had been used and could have increased further if there have been accidental dura puncture. Also using spinal anesthesia was economical although it should be done cautiously as we are giving spinal anesthesia above the level of termination of spinal cord.

We used a narrow gauze (26G) spinal needle which minimized the trauma to the patient and the chances of PDPH, which was more if 16 or 18G epidural needle had been used and could have increased further if there have been accidental dura puncture. Also using spinal anesthesia was economical although it should be done cautiously as we are giving spinal anesthesia above the level of termination of spinal cord. PMID:28928589

Toward a Model of Human Information Processing for Decision-Making and Skill Acquisition in Laparoscopic Colorectal Surgery.

PubMed

White, Eoin J; McMahon, Muireann; Walsh, Michael T; Coffey, J Calvin; O Sullivan, Leonard

To create a human information-processing model for laparoscopic surgery based on already established literature and primary research to enhance laparoscopic surgical education in this context. We reviewed the literature for information-processing models most relevant to laparoscopic surgery. Our review highlighted the necessity for a model that accounts for dynamic environments, perception, allocation of attention resources between the actions of both hands of an operator, and skill acquisition and retention. The results of the literature review were augmented through intraoperative observations of 7 colorectal surgical procedures, supported by laparoscopic video analysis of 12 colorectal procedures. The Wickens human information-processing model was selected as the most relevant theoretical model to which we make adaptions for this specific application. We expanded the perception subsystem of the model to involve all aspects of perception during laparoscopic surgery. We extended the decision-making system to include dynamic decision-making to account for case/patient-specific and surgeon-specific deviations. The response subsystem now includes dual-task performance and nontechnical skills, such as intraoperative communication. The memory subsystem is expanded to include skill acquisition and retention. Surgical decision-making during laparoscopic surgery is the result of a highly complex series of processes influenced not only by the operator's knowledge, but also patient anatomy and interaction with the surgical team. Newer developments in simulation-based education must focus on the theoretically supported elements and events that underpin skill acquisition and affect the cognitive abilities of novice surgeons. The proposed human information-processing model builds on established literature regarding information processing, accounting for a dynamic environment of laparoscopic surgery. This revised model may be used as a foundation for a model describing robotic surgery. Copyright © 2017 Association of Program Directors in Surgery. Published by Elsevier Inc. All rights reserved.

Laparoscopy, originally pioneered by gynecologists, was first adopted by general surgeons in the late 1980s. Since then, laparoscopy has been adopted in the surgical specialties and colorectal surgery for treatment of benign and malignant disease. Formal laparoscopic training became a required component of surgery residency programs as validated by the Fundamentals of Laparoscopic Surgery curriculum; however, some surgeons may be more apprehensive of widespread adoption of minimally invasive techniques. Although an overall increase in the use of laparoscopy in colorectal surgery is anticipated over a 10-year period, it is unknown if a similar increase will be seen in higher risk or more acutely ill patients. Using the American College of Surgeons (ACS) National Surgical Quality Improvement Program (NSQIP) database from 2005-2014, colorectal procedures were identified by Current Procedural Terminology codes and categorized to open or laparoscopic surgery. The proportion of colorectal surgeries performed laparoscopically was calculated for each year. Separate descriptive statistics was performed and categorized by age and body mass index (BMI). American Society of Anesthesiology (ASA) classification and emergency case status variables were added to the project to help assess complexity of cases. During the 10-year study period, the number of colorectal cases increased from 3114 in 2005 to 51,611 in 2014 as more hospitals joined NSQIP. A total of 277,376 colorectal cases were identified; of which, 114,359 (41.2%) were performed laparoscopically. The use of laparoscopy gradually increased each year, from 22.7% in 2005 to 49.8% in 2014. Laparoscopic procedures were most commonly performed in the youngest age group (18-49 years), overweight and obese patients (BMI 25-34.9), and in ASA class 1-2 patients. Over the 10-year period, there was a noted increase in the use of laparoscopy in every age, BMI, and ASA category, except ASA 5. The percent of emergency cases receiving laparoscopic surgery also doubled from 5.5% in 2005 to 11.5% in 2014. Over a 10-year period, there was a gradual increase in the use of laparoscopy in colorectal surgery. Further, there was a consistent increase of laparoscopic surgery in all age groups, including the elderly, in all BMI classes, including the obese and morbidly obese, and in most ASA classes, including ASA 3-4, as well as in emergency surgeries. These trends suggest that minimally invasive colorectal surgery appears to be widely adopted and performed on more complex or higher risk patients. Copyright © 2017 Elsevier Inc.

The therapeutic benefits of extraperitoneal colostomy with laparoscopic surgery remain unclear. The aim of this study was to investigate the relationship between the route for stoma creation with laparoscopic surgery and stoma-related complications, especially parastomal hernia (PSH). From January 2007 to March 2015, a total of 59 patients who underwent laparoscopic abdominoperineal resection or Hartmann procedure were investigated. Patient demographic and treatment characteristics, including stoma-related complications, were analyzed retrospectively. Transperitoneal and extraperitoneal colostomy were performed in 29 and 30 patients, respectively. Median follow-up duration was 21 months (range: 2-95). Patient demographic and treatment characteristics were comparable between the transperitoneal group (TPG) and the extraperitoneal group (EPG). PSH developed in 12 (41 %) patients in TPG, and 4 (13 %) patients in EPG (p = 0.020). The incidence of other stoma-related complications and non-stoma-related complications did not differ significantly between TPG and EPG. No patient characteristics except for transperitoneal route for stoma creation were associated with PSH development. The extraperitoneal route for stoma creation is associated with a significantly lower incidence of PSH development after laparoscopic surgery. Whenever possible, extraperitoneal colostomy should be recommended, even with laparoscopic surgery.

To evaluate resident case volume after discontinuation of a laparoscopic surgery fellowship, and to examine disparities in patient care over the same time period. Resident case logs were compared for a 2-year period before and 1 year after discontinuing the fellowship, using a 2-sample t test. Databases for bariatric and esophageal surgery were reviewed to compare operative time, length of stay (LOS), and complication rate by resident or fellow over the same time period using a 2-sample t test. Increases were seen in senior resident advanced laparoscopic (Mean Fellow Year = 21 operations vs Non Fellow Year = 61, P < 0.01), esophageal (1 vs 11, P < .01) and bariatric volume (9 vs 36, P < .01). Junior resident laparoscopic volume increased (P < 0.05). No difference in LOS or complication rate was seen with resident vs fellow assistant. Operative time was greater for gastric bypass with resident assistant (152 ± 51 minutes vs 138 ± 53, P < .05). Discontinuing a laparoscopic fellowship significantly increases resident case volume in laparoscopic surgery. Operative time for complex operations may increase in the absence of a fellow. Other patient outcomes are not affected by this change. Copyright © 2011 Mosby, Inc. All rights reserved.

The recent development of open magnetic resonance imaging (MRI) has provided an opportunity for the next stage of image-guided surgical and interventional procedures. The purpose of this study was to evaluate the feasibility of laparoscopic surgery under the pneumoperitoneum with the system of an open MRI operating theater. Five patients underwent laparoscopic surgery with a real-time augmented reality navigation system that we previously developed in a horizontal-type 0.4-T open MRI operating theater. All procedures were performed in an open MRI operating theater. During the operations, the laparoscopic monitor clearly showed the augmented reality models of the intraperitoneal structures, such as the common bile ducts and the urinary bladder, as well as the proper positions of the prosthesis. The navigation frame rate was 8 frames per min. The mean fiducial registration error was 6.88 ± 6.18 mm in navigated cases. We were able to use magnetic resonance-incompatible surgical instruments out of the 5-Gs restriction area, as well as conventional laparoscopic surgery, and we developed a real-time augmented reality navigation system using open MRI. Laparoscopic surgery with our real-time augmented reality navigation system in the open MRI operating theater is a feasible option.

To compare the outcomes of management of incarcerated inguinal hernia by open versus laparoscopic approach. This is a retrospective analysis of incarcerated inguinal hernina in a paediatric surgery centre involving four consultants. Manual reduction was attempted in all and failure was managed by emergency surgery. The laparoscopy group had 27 patients. Four patients failed manual reduction and underwent emergency laparoscopic surgery. Three of them had small bowel strangulation which was reduced laparoscopically. The strangulated bowel was dusky in colour initially but changed to normal colour subsequently under vision. The fourth patient required appendectomy for strangulated appendix. One patient had concomitant repair of umbilical hernia and one patient had laparoscopic pyloromyotomy at the same time. One patient had testicular atrophy, one had hydrocoele and one had recurrence of hernia on the asymptomatic side. The open surgery group had 45 patients. Eleven patients had failed manual reduction requiring emergency surgery, of these two required resection and anastomosis of small intestine. One patient in this group had concomitant repair of undescended testis. There was no recurrence in this group, one had testicular atrophy and seven had metachronous hernia. Both open herniotomy and laparoscopic repair offer safe surgery with comparable outcomes for incarcerated inguinal hernia in children. Laparoscopic approach and hernioscopy at the time of open approach appear to show the advantage of repairing the contralateral patent processus vaginalis at the same time and avoiding metachronous inguinal hernia.

There is ongoing debate whether laparoscopic right colectomy is superior to open surgery. The purpose of this study was to address this issue and arrive at a consensus using data from a national database. Patients who underwent elective open or laparoscopic right colectomy for colorectal cancer during the period 2009-2013 were identified from the Dutch Surgical Colorectal Audit. Complications that occurred within 30 days after surgery and 30-day mortality rates were calculated and compared between open and laparoscopic resection. In total, 12,006 patients underwent elective open or laparoscopic surgery for right-sided colorectal cancer. Of these, 6,683 (55.7%) underwent open resection and 5,323 (44.3%) underwent laparoscopic resection. Complications occurred within 30 days after surgery in the laparoscopic group in 26.1% of patients and in 32.1% of patients in the open group (p < 0.001). Thirty-day mortality was also significantly lower in the laparoscopic group (2.2 vs. 3.6% p < 0.001). In this non-randomized, descriptive study conducted in the Netherlands, open right colectomy seems to have a higher risk for complications and mortality as compared to laparoscopic right colectomy, even after correction for confounding factors. © 2018 S.

Most researchers believe that the presence of large epiphrenic diverticulum (ED) with severe symptoms should lead to the consideration of surgical options. The choice of minimally invasive techniques and whether Heller myotomy with antireflux fundoplication should be employed after diverticulectomy became points of debate. The aim of this study was to describe how to perform laparoscopic transhiatal diverticulectomy (LTD) and oesophagomyotomy with the aid of intraoperative gastrointestinal (GI) endoscopy and how to investigate whether the oesophagomyotomy should be performed routinely after LTD. From 2008 to 2013, 11 patients with ED underwent LTD with the aid of intraoperative GI endoscopy at our department. Before surgery, 4 patients successfully underwent oesophageal manometry: Oesophageal dysfunction and an increase of the lower oesophageal sphincter pressure (LESP) were found in 2 patients. There were 2 cases of conversion to an open transthoracic procedure. Six patients underwent LTD, Heller myotomy and Dor fundoplication; and 3 patients underwent only LTD. The dysphagia and regurgitation 11 patients experienced before surgery improved significantly. Motor function studies showed that there was no oesophageal peristalsis in 5 patients during follow-up, while 6 patients showed seemingly normal oesophageal motility. The LESP of 6 patients undergoing LTD, myotomy and Dor fundoplication was 16.7 ± 10.2 mmHg, while the LESPs of 3 patients undergoing only LTD were 26 mmHg, 18 mmHg and 21 mmHg, respectively. In 4 cases experiencing LTD, myotomy and Dor fundoplication, the gastro-oesophageal reflux occurred during the sleep stage. LTD constitutes a safe and valid approach for ED patients with severe symptoms. As not all patients with large ED have oesophageal disorders, according to manometric and endoscopic results, surgeons can categorise and decide whether or not myotomy and antireflux surgery after LTD will be conducted.

Structured Abstract Background Ostomy surgery is common and has traditionally been associated with high rates of morbidity and mortality, suggesting an important target for quality improvement. Objective To evaluate the variation in outcomes after ostomy creation surgery within Michigan in order to identify targets for quality improvement. Design Retrospective cohort study. Setting The 34-hospital Michigan Surgical Quality Collaborative (MSQC). Patients Patients undergoing ostomy creation surgery between 2006-2011. Main outcome measures We evaluated hospitals' morbidity and mortality rates after risk-adjustment (age, comorbidities, emergency v. elective, procedure type). Results 4,250 patients underwent ostomy creation surgery; 3,866 (91.0%) procedures were open and 384 (9.0%) were laparoscopic. Unadjusted morbidity and mortality rates were 43.9% and 10.7%, respectively. Unadjusted morbidity rates for specific procedures ranged from 32.7% for ostomy-creation-only procedures to 47.8% for Hartmann's procedures. Risk-adjusted morbidity rates varied significantly between hospitals, ranging from 31.2% (95%CI 18.4-43.9) to 60.8% (95%CI 48.9-72.6). There were five statistically-significant high-outlier hospitals and three statistically-significant low-outlier hospitals for risk-adjusted morbidity. The pattern of complication types was similar between high- and low-outlier hospitals. Case volume, operative duration, and use of laparoscopic surgery did not explain the variation in morbidity rates across hospitals. Conclusions Morbidity and mortality rates for modern ostomy surgery are high. While this type of surgery has received little attention in healthcare policy, these data reveal that it is both common and uncommonly morbid. Variation in hospital performance provides an opportunity to identify quality improvement practices that could be disseminated among hospitals. PMID:24819104

Endopyelotomy and laparoscopic pyeloplasty are established procedures for ureteropelvic junction obstruction (UPJO) and historically a high failure rate has been observed in poorly functioning units with UPJ obstruction. The aim of this study is to compare the results of laparoscopic pyeloplasty with endopyelotomy in poorly functioning renal units, i.e., GFR under 25 ml/min. Materials and Methods: Retrospective analysis of all the patients who underwent either laparoscopic pyeloplasty or endopyelotomy for ureteropelvic junction obstruction in poorly functioning units between January 1998 and June 2005 was done. Follow-up renal scans, done at three, six, 12 months and yearly thereafter, were studied. Success was defined as symptomatic relief and/ or improvement in function (10% over baseline) in renal scan. Results: There were 23 patients in the endopyelotomy group and 15 patients in the laparoscopic pyeloplasty group with mean age of 25.3 years (9-53) and 26 years (10-44), respectively. Mean pelvic volume was 41.2 8cc ± 9.5 and 39.1cc ± 9.85 in the endopyelotomy group and laparoscopic pyeloplasty group, respectively. Mean preoperative GFR was 17.4 ± 5.7 ml/min and 21 ± 4.5 ml/min in the endopyelotomy group and laparoscopic pyeloplasty group, respectively and mean postoperative GFR was 21 ± 3.5 ml/min and 22 ± 3.9 ml/min, respectively. Eighteen and 11 patients were symptomatic in ethe ndopyelotomy group and laparoscopic pyeloplasty group, respectively while symptomatic improvement was seen in 14 and 11 patients, respectively. Mean follow-up was 12 months in the laparoscopy group and 28 months in the endopyelotomy group. Success rate was better for laparoscopic surgery group (15/15 = 100%) than for endopyelotomy (18/23 = 78.26%). Conclusions: Though the improvement in renal function is less in patients with UPJO with poorly functioning kidneys undergoing endopyelotomy or laparoscopic pyeloplasty, laparoscopic pyeloplasty gives better results in the form of symptomatic relief; however, renal function remains stable whichever the approach chosen.

The laparoscopic approach to repair of inguinal hernia has proven advantages over open repair. Repair of more technically challenging hernias, such as patients previously receiving prostatectomy, has been less studied and may not have these advantages. We aimed to compare safety, feasibility, and clinical outcomes for repairs in patients who previously underwent prostatectomy to control subjects. We undertook a case-control study using a prospectively collected database. From 2004, all patients were routinely offered totally extraperitoneal laparoscopic repair. All patients who had a history of previous prostatectomy were identified and compared to a matched control group. Both operative and follow-up data were analyzed. Of 987 patients undergoing surgery during this time period, 52 prostatectomy patients were identified (44% open, 44% robotic, 3% laparoscopic) and matched to 102 control subjects. Accounting for bilateral repairs, 203 hernia repairs had been performed. Patients were well matched for age and American Society of Anesthesiologists score. Operative time was longer for prostatectomy patients (mean, 70 vs. 52 min, p < 0.0001); however, this reduced over time when comparing the first and second half prostatectomy patients (77 vs. 63 min, p = 0.144). Overall, there were no intraoperative or major postoperative complications and only one conversion (prostatectomy group). No significant differences were found for rates of minor postoperative complications, length of stay, or recurrence (n = 1, control group). No difference was observed for chronic pain, and all patients in each group reported satisfaction with surgery at contemporary follow-up. In experienced hands, totally extraperitoneal inguinal hernia repair for patients previously having undergone prostatectomy is safe and has equivalent outcomes to patients not having undergone prostatectomy, and is an option to open repair. Understandably, slightly longer operative times may be justified, given the benefits of early discharge and less postoperative pain after laparoscopic surgery.

Complex enterovisceral fistulas are internal fistulas joining a "diseased" organ to any intra-abdominal "victim" organ, with the exception of ileoileal fistulas. Few publications have addressed laparoscopic surgery for complex fistulas in Crohn's disease. The aim of this study was to evaluate the feasibility of such an approach. This study is a retrospective, case-match review. This study was conducted at a tertiary academic hospital. : All patients who underwent a laparoscopic ileocecal resection for complex enterovisceral fistulas between January 2004 and August 2011 were included. They were matched to a control group undergoing operation for nonfistulizing Crohn's disease according to age, sex, nutritional state, preoperative use of steroids, and type of resection performed. Matching was performed blind to the peri- and postoperative results of each patient. The 2 groups were compared in terms of operative time, conversion to open surgery, morbidity and mortality rates, and length of stay. Eleven patients presenting with 13 complex fistulas were included and matched with 22 controls. Group 1 contained 5 ileosigmoid fistulas (38%), 3 ileotransverse fistulas (23%), 3 ileovesical fistulas (23%), 1 colocolic fistula (8%), and 1 ileosalpingeal fistula (8%). There were no significant differences between the groups in terms of operative time (120 (range, 75-270) vs 120 (range, 50-160) minutes, p = 0.65), conversion to open surgery (9% vs 0%, p = 0.33), stoma creation (9% vs 14%, p = 1), global postoperative morbidity (18% vs 32%, p = 0.68), and major complications (Dindo III: 0% vs 9%, p = 0.54; Dindo IV: 0% vs 0%, p = 1), as well as in terms of length of stay (8 (range, 7-32) vs 9 (range, 5-17) days, p = 0.72). No patients died. This is a retrospective review with a small sample size. A laparoscopic approach for complex fistulas is feasible in Crohn's disease, with outcomes similar to those reported for nonfistulizing forms.

Little is known about the effects of small doses of dexamethasone used for the prophylaxis of postoperative nausea and vomiting on the innate host response. We studied the influence of dexamethasone 4 mg on the perioperative plasma concentrations of interleukins after laparoscopic cholecystectomy. We hypothesised that there would be differences in pro-inflammatory interleukin concentrations in patients who received dexamethasone. A randomised controlled study. University hospital. Forty-six patients undergoing laparoscopic cholecystectomy under total intravenous anaesthesia were allocated randomly into one of two study groups; 42 patients completed the study. Patients in group 1 (dexamethasone, n = 22) received dexamethasone 4 mg and group 2 (n = 20) acted as controls. Plasma levels of tumour necrosis factor alpha and interleukins 1β, 6, 8, 10 and 13 were measured before anaesthesia, before surgery and 2 and 24 h after surgery. The frequency and number of episodes of postoperative nausea and vomiting were recorded. Areas under the curve of the percentage variation of interleukins 6 and 8 were significantly lower in the dexamethasone group. There were no significant differences between groups in the areas under the curve for tumour necrosis factor alpha and interleukins 1β, 10 and 13. The greatest variation in interleukin concentrations was 2 h postoperatively, when the concentration of interleukin 6 was greater in the control group, whereas the concentration of interleukin 10 was higher in the dexamethasone group. Twenty-four hours after surgery, only the concentration of interleukin 6 remained significantly increased in both groups (P = 0.001 and P = 0.002, respectively). There were no significant differences between groups in respect of postoperative nausea and vomiting. Prophylactic dexamethasone given before laparoscopic cholecystectomy produced a significant decrease in concentrations of interleukins 6 and 8. Further studies are needed to investigate the clinical implications of these findings.

The cost of ignoring acute cholecystectomy.

Biliary symptoms whilst awaiting elective cholecystectomy are common, resulting in hospital admission, further investigation and increased hospital costs. Immediate cholecystectomy during the first admission is safe and effective, even when performed laparoscopically, but acute laparoscopic cholecystectomy has only recently become increasingly commonplace in the UK. This study was designed to quantify this problem in our hospital and its cost implications. The case notes of all patients undergoing laparoscopic cholecystectomy in our hospital between January 2004 and June 2005 were examined for details of hospital admissions with biliary symptoms or complications whilst waiting for elective cholecystectomy. Additional bed occupancy and radiological investigations were recorded and these costs to the trust calculated. We compared the potential tariff income to the hospital trust for the actual management of these patients and if a policy of acute laparoscopic cholecystectomy on first admission were in place. In the 18-month study period, 259 patients (202 females) underwent laparoscopic cholecystectomy. Of these, 147 presented as out-patients and only 11% required hospital admission because of biliary symptoms whilst waiting for elective surgery. There were 112 patients who initially presented acutely and were managed conservatively. Twenty-four patients were re-admitted 37 times, which utilised 231 hospital bed-days and repeat investigations costing over 40,000 pounds. There would have been a marginal increase in tariff income if a policy of acute laparoscopic cholecystectomy had been in place. Adoption of a policy of acute laparoscopic cholecystectomy on the index admission would result in substantial cost savings to the trust, reduce elective cholecystectomy waiting times and increase tariff income.

To describe the use and outcome of a single, simple continuous, barbed suture line for prophylactic, total laparoscopic gastropexy in dogs. Multi-center, retrospective case series. Sixty-three client-owned dogs. Medical records of dogs undergoing total laparoscopic gastropexy using a barbed suture at 4 academic veterinary hospitals from 2011-2015 were reviewed. Data collected included signalment, procedure time, procedure-associated complications, short-term complications, and long-term outcome. All procedures were performed under general anesthesia in dorsal to dorsal-left oblique recumbency. Laparoscopic ports were placed on ventral midline in 1 of 3 port configurations, and 5 mm laparoscopic needle drivers were used for intracorporeal sutured gastropexy with unidirectional barbed suture. The gastropexy was positioned just caudal to the 13th rib, 2-4 cm lateral to the rectus abdominis muscle. Sixty-three dogs underwent total laparoscopic gastropexy with a single, simple continuous, barbed suture line. Median gastropexy surgery time was 70 minutes (interquartile range [IQR] 60-90 minutes). One dog sustained splenic laceration from Veress needle penetration during initial abdominal insufflation. Short term (>24 hours to 6 months postoperative) complications included incisional seroma formation (n = 2) and suture reaction (n = 1). Long term (>6 months postoperative) complications included intermittent regurgitation and chronic diarrhea in 1 dog. Fifteen dogs had postoperative ultrasound and all had intact gastropexy sites. Total laparoscopic barbed gastropexy using a single, simple continuous, barbed suture line in dogs is safe and results in an intact gastropexy long term. © 2016 The American College of Veterinary Surgeons.

Hybrid laparoscopic and robotic ultrasound-guided radiofrequency ablation-assisted clampless partial nephrectomy.

To describe a clampless approach made possible by creating an avascular plane of tissue with radiofrequency ablation. Laparoscopic partial nephrectomy is slowly gaining acceptance as a method to treat small (<4 cm) and select moderate (<7 cm) renal masses. The intricacies of laparoscopic suturing, which result in prolonged warm ischemia times, have delayed the widespread acceptance of this technique among urologists. Laparoscopic suturing to close the collecting system was done using the da Vinci robot. An avascular plane of tissue from coagulation necrosis was achieved with the Habib 4X radiofrequency ablation device and the Rita 1500X generator. Typically, we used a power setting of 50 W but have found settings as low as 25 W necessary to provide hemostasis for larger vessels. The tumor was then sharply excised with a negative margin using robotic scissors and electrocautery to facilitate tissue cutting. Retrograde injection of methylthioninium chloride and saline through an externalized ureteral catheter allowed for precise sutured closure of the collecting system. FloSeal and BioGlue were then applied, making surgical bolsters or parenchymal sutures unnecessary. Intraoperative histologic evaluation of the surgical margin and repeat resection of the tumor bed was possible because the renal hilum was not clamped, and no warm ischemia was used. This technique, which combines the improving technologies of robotic surgery, intraoperative laparoscopic ultrasonography, and radiofrequency ablation, might make more surgeons comfortable with the intricacies of laparoscopic suturing and eliminate prolonged warm ischemia times. Overall, this method should result in more patients being able to undergo minimally invasive laparoscopic partial nephrectomy.

Economic impact of laparoscopic instrumentation: a company perspective.

Swem, T; Fazzalari, R

This report represents findings concerning the economic impact of laparoscopic surgery. Specifically, the study addresses hospital costs, and not the hospital charges often given attention by studies in the literature. Hospital expenditures for the equipment and instrumentation required for laparoscopic surgery are important cost factors in laparoscopic surgery. Data for determining hospital costs was obtained from nine hospitals throughout the United States. At each hospital, a research team spent four to five days interviewing surgeons, OR staff, hospital administrators and other personnel as well as gathering data. Analysis of operating room equipment and supplies indicates that single-use laparoscopic instruments are a cost-effective alternative to reusable instruments. In addition, single-use instruments have many benefits that were not possible to quantify accurately in this study.

Complications aroused from Meckel's diverticulum tend to developed in children. Children presented with abdominal pain, intestinal obstruction, intussusception or gastrointestinal bleeding may actually suffered from complicated Meckel's diverticulum. With the advancement of minimally invasive surgery (MIS) in children, the use of laparoscopy in the diagnosis and subsequent laparoscopic excision of Meckel's diverticulum has gained popularity. Recently, single incision laparoscopic surgery (SILS) has emerged as a new technique in minimally invasive surgery. This review offers the overview in the development of MIS in the management of children suffered from Meckel's diverticulum. The current evidence in different laparoscopic techniques, including conventional laparoscopy, SILS, the use of special laparoscopic instruments, intracorporeal diverticulectomy and extracorporeal diverticulectomy in the management of Meckel's diverticulum in children were revealed.

As minimal invasive abdominal surgery became established in the last decades, further minimization of the surgical access is in the focus now. Although laparoscopic instruments and camera systems become diminished in size there is still a need for a minilaparotomy for extraction and anastomosis of organs. NOTES (Natural orifice transluminal endoscopic surgery) aims to avoid this minilaparotomy. Consequently, laparoscopic-assisted procedures become pure laparoscopic surgery. The transvaginal access is the most common performed NOTES procedure. The acceptance in women is high. The feasibility of NOTES cholecystectomy is scientifically proofed. The procedure is associated with less pain than the common four-port laparoscopic surgery and does not interfere with the sexual well-being. There are no access-related infections; the abdominal wound infection and incisional hernia rate are low. In left sided colonic resection the transrectal access makes NOTES available for both genders.

The aim of the study was a retrospective analysis of the medical records of patients who underwent surgery due to deep infiltrating rectovaginal endometriosis (mainly with the use of the 'shaving' technique). We analysed 160 cases of patients who underwent surgery due to the deep infiltrating rectovaginal endometriosis in our ward between 2003-2014. Depending on lesion localization, disease severity and clinical characteristics, three possible ways of operation were proposed: laparoscopic, vaginal or a combined vagino-laparoscopic approach. A total of 120 patients underwent laparoscopic removal of the endometrial lesions, whereas 17 were operated vaginally and 23 with the use of the combined approach. Nodule resection was successfully performed in all cases. The combined vagino-laparoscopic operations were characterized by the longest operating time. The rate of perioperative complications was low in the group of patients who underwent laparoscopic or combined operations. The necessity of bowel wall suturing occurred in 15 cases. This procedure was performed in order to strengthen the bowel wall (in cases when no perforation occurred) or due to bowel resection during surgery. Unexpected bowel perforation occurred in only 5 cases. Conclusions: Vaginal, laparoscopic and the combined vagino-laparoscopic surgeries can be safely performed in cases of deep rectovaginal endometriosis.

Video games are mainly considered to be of entertainment value in our society. Laparoscopic surgery and video games are activities similarly requiring eye-hand and visual-spatial skills. Previous studies have not conclusively shown a positive correlation between video game experience and improved ability to accomplish visual-spatial tasks in laparoscopic surgery. This study was an attempt to investigate this relationship. The aim of the study was to investigate whether previous video gaming experience affects the baseline performance on a laparoscopic simulator trainer. Newly qualified medical officers with minimal experience in laparoscopic surgery were invited to participate in the study and assigned to the following groups: gamers (n = 20) and non-gamers (n = 20). Analysis included participants' demographic data and baseline video gaming experience. Laparoscopic skills were assessed using a laparoscopic simulator trainer. There were no significant demographic differences between the two groups. Each participant performed three laparoscopic tasks and mean scores between the two groups were compared. The gamer group had statistically significant better results in maintaining the laparoscopic camera horizon ± 15° (p value = 0.009), in the complex ball manipulation accuracy rates (p value = 0.024) and completed the complex laparoscopic simulator task in a significantly shorter time period (p value = 0.001). Although prior video gaming experience correlated with better results, there were no significant differences for camera accuracy rates (p value = 0.074) and in a two-handed laparoscopic exercise task accuracy rates (p value = 0.092). The results show that previous video-gaming experience improved the baseline performance in laparoscopic simulator skills. Copyright © 2017 IJS Publishing Group Ltd. Published by Elsevier Ltd.

Laparoscopic sleeve gastrectomy is gaining popularity in the US; however, there has been no study examining the use of sleeve gastrectomy at a national level and its impact on the use of other bariatric operations. The aim of this study was to examine contemporary changes in use and outcomes of bariatric surgery performed at academic medical centers. Using ICD-9 diagnosis and procedure codes, clinical data obtained from the University HealthSystem Consortium database for all bariatric procedures performed for the treatment of morbid obesity between October 1, 2008 and September 30, 2012 were reviewed. Quartile trends in use for the 3 most commonly performed bariatric operations were examined, and a comparison of perioperative outcomes between procedures was performed within a subset of patients with minor severity of illness. A total of 60,738 bariatric procedures were examined. In 2008, the makeup of bariatric surgery consisted primarily of gastric bypass (66.8% laparoscopic, 8.6% open), followed by laparoscopic gastric banding (23.8%). In 2012, there was a precipitous increase in use of laparoscopic sleeve gastrectomy (36.3 %), with a concurrent reduction in the use of laparoscopic (56.4%) and open (3.2%) gastric bypass, and a major reduction in laparoscopic gastric banding (4.1%). The length of hospital stay, in-hospital morbidity and mortality, and costs for laparoscopic sleeve gastrectomy were found to be between those of laparoscopic gastric banding and laparoscopic gastric bypass. Within the context of academic medical centers, there has been a recent change in the makeup of bariatric surgery. There has been an increase in the use of laparoscopic sleeve gastrectomy, which has had an impact primarily on reducing the use of laparoscopic adjustable gastric banding.

CURRENT STATUS OF RESIDENCY TRAINING IN LAPAROSCOPIC SURGERY IN BRAZIL: A CRITICAL REVIEW

PubMed Central

NÁCUL, Miguel Prestes; CAVAZZOLA, Leandro Totti; de MELO, Marco Cezário

2015-01-01

Introduction The surgeon's formation process has changed in recent decades. The increase in medical schools, new specialties and modern technologies induce an overhaul of medical education. Medical residency in surgery has established itself as a key step in the formation of the surgeon, and represents the ideal and natural way for teaching laparoscopy. However, the introduction of laparoscopic surgery in the medical residency programs in surgical specialties is insufficient, creating the need for additional training after its termination. Objective To review the surgical teaching ways used in services that published their results. Methods Survey of relevant publications in books, internet and databases in PubMed, Lilacs and Scielo through july 2014 using the headings: laparoscopy; simulation; education, medical; learning; internship and residency. Results The training method for medical residency in surgery focused on surgical procedures in patients under supervision, has proven successful in the era of open surgery. However, conceptually turns as a process of experimentation in humans. Psychomotor learning must not be developed directly to the patient. Training in laparoscopic surgery requires the acquisition of psychomotor skills through training conducted initially with surgical simulation. Platforms based teaching problem solving as the Fundamentals of Laparoscopic Surgery, developed by the American Society of Gastrointestinal Endoscopic Surgery and the Laparoscopic Surgical Skills proposed by the European Society of Endoscopic Surgery has been widely used both for education and for the accreditation of surgeons worldwide. Conclusion The establishment of a more appropriate pedagogical process for teaching laparoscopic surgery in the medical residency programs is mandatory in order to give a solid surgical education and to determine a structured and safe professional activity.

Background: Transversus abdominis plane (TAP) block has been used to provide intra- and post-operative analgesia with single incision laparoscopic (SIL) bariatric and gynecological surgery with mixed results. Its efficacy in providing analgesia for SIL cholecystectomy (SILC) via the same approach remains unexplored. Aims: The primary objective of our study was to compare the efficacy of bilateral TAP block with local anesthetic infiltration for perioperative analgesia in patients undergoing SILC. Settings and Design: This was a prospective, randomized, controlled, double-blinded trial performed in a tertiary care hospital. Materials and Methods: Forty-two patients undergoing SILC were randomized to receive either ultrasound-guided (USG) bilateral mid-axillary TAP blocks with 0.375% ropivacaine or local anesthetic infiltration of the port site. The primary outcome measure was the requirement of morphine in the first 24 h postoperatively. Statistical Analysis: The data were analyzed using t-test, Mann–Whitney test or Chi-square test. Results: The 24 h morphine requirement (mean ± standard deviation) was 34.57 ± 14.64 mg in TAP group and 32.76 ± 14.34 mg in local infiltration group (P = 0.688). The number of patients requiring intraoperative supplemental fentanyl in TAP group was 8 and in local infiltration group was 16 (P = 0.028). The visual analog scale scores at rest and on coughing were significantly higher in the local infiltration group in the immediate postoperative period (P = 0.034 and P = 0.007, respectively). Conclusion: USG bilateral TAP blocks were not effective in decreasing 24 h morphine requirement as compared to local anesthetic infiltration in patients undergoing SILC although it provided some analgesic benefit intraoperatively and in the initial 4 h postoperatively. Hence, the benefits of TAP blocks are not worth the effort and time spent for administering them for this surgery. PMID:27746552

Laparoscopic hepatectomy is progressively gaining popularity. However, it is still unclear whether the laparoscopic approach offers cost advantages compared with the open approach, especially when major hepatectomies are required. Data providing useful insights into the costs of the laparoscopic approach for clinicians and hospitals are needed. The aim of this study is to assess the financial implications of the laparoscopic approach for two standardized minor and major hepatectomies: left lateral sectionectomy and right hepatectomy. A cost comparison analysis of patients undergoing laparoscopic right hepatectomy (LRH) and laparoscopic left lateral sectionectomy (LLLS) versus the open counterparts was performed. Data considered for the comparison analysis were operative costs (theatre cost, consumables and surgeon/anaesthetic labour cost), postoperative costs (hospital stay, complication management and readmissions) and overall costs. A total of 149 patients were included: 38 patients underwent LRH and 46 open right hepatectomy (ORH); 46 patients underwent LLLS and 19 open left lateral sectionectomy (OLLS). For LRH the mean operative, postoperative and overall costs were £10,181, £4,037 and £14,218; for ORH the mean operative, postoperative and overall costs were £6,483 (p < 0.0001), £10,304 (p < 0.0001) and £16,787 (p = 0.886). Regarding LLLS, the mean operative, postoperative and overall costs were £5,460, £2,599 and £8,059; for OLLS the mean operative, postoperative and overall costs were £5,841 (p = 0.874), £5,796 (p < 0.0001) and £11,637 (p = 0.0001). Our data support the cost advantage of the laparoscopic approach for left lateral sectionectomy and the cost neutrality for right hepatectomy.

Background There is a need for investigating the analgesic method as part of early recovery after surgery tailored for laparoscopic colorectal cancer (LCRC) surgery. In this randomized trial, we aimed to investigate the analgesic efficacy of an inverse ‘v’ shaped bilateral, subfascial ropivacaine continuous infusion in LCRC surgery. Methods Forty two patients undergoing elective LCRC surgery were randomly allocated to one of two groups to receive either 0.5% ropivacaine continuous infusion at the subfascial plane (n = 20, R group) or fentanyl intravenous patient controlled analgesia (IV PCA) (n = 22, F group) for postoperative 72 hours. The primary endpoint was the visual analogue scores (VAS) when coughing at postoperative 24 hours. Secondary end points were the VAS at 1, 6, 48, and 72 hours, time to first flatus, time to first rescue meperidine requirement, rescue meperidine consumption, length of hospital stay, postoperative nausea and vomiting, sedation, hypotension, dizziness, headache, and wound complications. Results The VAS at rest and when coughing were similar between the groups throughout the study. The time to first gas passage and time to first rescue meperidine at ward were significantly shorter in the R group compared to the F group (P = 0.010). Rescue meperidine was administered less in the R group; however, without statistical significance. Other study parameters were not different between the groups. Conclusions Ropivacaine continuous infusion with an inverse ‘v ’ shaped bilateral, subfascial catheter placement showed significantly enhanced bowel recovery and analgesic efficacy was not different from IV PCA in LCRC surgery.

We present health-related quality of life (HRQoL) data on a cohort of patients undergoing upper urinary tract laparoscopy for a variety of benign and malignant conditions. The Short Form 8 (SF-8) Health Survey is a validated HRQoL questionnaire that calculates scores for physical (PCS8) and mental (MCS8) components of health. It was administered prospectively to 58 patients. Radical nephrectomy or nephroureterectomy was carried out for upper tract malignancy (n = 21). Laparoscopy for benign disease (n = 37) included simple nephrectomy for giant hydronephrosis and small non-functioning kidneys, de-roofing of renal cysts and pyeloplasty. Data were collected before and 6 weeks after surgery. The mean pre- and postsurgery scores were 45.99; 47.43 and 43.93; 51.54 for PCS8 and MCS8 respectively. With regard to the PCS8 score, there was no significant difference before or after surgery (p = 0.585) or when analysing the benign (p = 0.343) or malignant (p = 0.509) groups individually. The MCS8 score, however, showed a significant increase after surgery (p < 0.0001). This remained significant when analysing just the benign (p < 0.0009) or the malignant (p < 0.0003) groups but neither group was more significant than the other (p = 0.750). Laparoscopic upper urinary tract surgery significantly improves mental and does not appear to reduce physical HRQoL in patients regardless of aetiology, 4 weeks following surgery. Interestingly, those operated on for malignant conditions do not have a greater improvement in mental health when compared with benign disease.

In order to improve the surgical treatment of rectal cancer, robot-assisted laparoscopy has been introduced. The robot has gained widespread use; however, the scientific basis for treatment of rectal cancer is still unclear. The aim of this study was to investigate whether robot-assisted laparoscopic rectal resection cause less perioperative pain than standard laparoscopic resection measured by the numerical rating scale (NRS score) as well as morphine consumption. Fifty-one patients were randomized to either laparoscopic or robot-assisted rectal resection at the Department of Surgery at Aarhus University Hospital in Denmark. The intra-operative analgetic consumption was recorded prospectively and registered in patient records. Likewise all postoperative medicine administration including analgesia was recorded prospectively at the hospital medical charts. All morphine analogues were converted into equivalent oral morphine by a converter. Postoperative pain where measured by numeric rating scale (NRS) every hour at the postoperative care unit and three times a day at the ward. Opioid consumption during operation was significantly lower during robotic-assisted surgery than during laparoscopic surgery (p=0.0001). However, there were no differences in opioid consumption or NRS in the period of recovery. We found no differences in length of surgery between the two groups; however, ten patients from the laparoscopic group underwent conversion to open surgery compared to one from the robotic group (p=0.005). No significant difference between groups with respect to complications where found. In the present study, we found that patients who underwent rectal cancer resection by robotic technique needed less analgetics during surgery than patients operated laparoscopically. We did, however, not find any difference in postoperative pain score or morphine consumption postoperatively between the robotic and laparoscopic group.

Laparoscopic entry: a review of Canadian general surgical practice

Compeau, Christopher; McLeod, Natalie T.; Ternamian, Artin

2011-01-01

Background Laparoscopic surgery has gained popularity over open conventional surgery as it offers benefits to both patients and health care practitioners. Although the overall risk of complications during laparoscopic surgery is recognized to be lower than during laparotomy, inadvertent serious complications still occur. Creation of the pneumoperitoneum and placement of laparoscopic ports remain a critical first step during endoscopic surgery. It is estimated that up to 50% of laparoscopic complications are entry-related, and most injury-related litigations are trocar-related. We sought to evaluate the current practice of laparoscopic entry among Canadian general surgeons. Methods We conducted a national survey to identify general surgeon preferences for laparoscopic entry. Specifically, we sought to survey surgeons using the membership database from the Canadian Association of General Surgeons (CAGS) with regards to entry methods, access instruments, port insertion sites and patient safety profiles. Laparoscopic cholecystectomy was used as a representative general surgical procedure. Results The survey was completed by 248 of 1000 (24.8%) registered members of CAGS. Respondents included both community and academic surgeons, with and without formal laparoscopic fellowship training. The demographic profile of respondents was consistent nationally. A substantial proportion of general surgeons (> 80%) prefer the open primary entry technique, use the Hasson trocar and cannula and favour the periumbilical port site, irrespective of patient weight or history of peritoneal adhesions. One-third of surgeons surveyed use Veress needle insufflation in their surgical practices. More than 50% of respondents witnessed complications related to primary laparoscopic trocar insertion. Conclusion General surgeons in Canada use the open primary entry technique, with the Hasson trocar and cannula applied periumbilically to establish a pneumoperitoneum for laparoscopic surgery. This surgical approach is remarkably consistent nationally, although considerably variant across other surgical subspecialties. Peritoneal entry remains an important patient safety issue that requires ongoing evaluation and study to ensure translation into safe contemporary clinical practice. PMID:21774882

Safety and Efficacy of Single Incision Laparoscopic Surgery for Total Extraperitoneal Inguinal Hernia Repair

PubMed Central

2011-01-01

Almost 20 years after the first laparoscopic inguinal hernia repair was performed, single incision laparoscopic surgery (SILS™) is set to revolutionize minimally invasive surgery. However, the loss of triangulation must be overcome before the technique can be popularized. This study reports the first 100 laparoscopic total extraperitoneal hernia repairs using a single incision. The study cohort comprised 68 patients with a mean age of 44 (range, 18 to 83): 36 unilateral and 32 bilateral hernias. Twelve patients also underwent umbilical hernia repair with the Ventralex patch requiring no additional incisions. A 2.5-cm to 3-cm crescentic incision within the confines of the umbilicus was performed. Standard dissecting instruments and 52-cm/5.5-mm/300 laparoscope were used. Operation times were 50 minutes for unilateral and 80 minutes for bilateral. There was one conversion to conventional 3-port laparoscopic repair and none to open surgery. Outpatient surgery was achieved in all (except one). Analgesic requirements were minimal: 8 Dextropropoxyphene tablets (range, 0 to 20). There were no intraoperative or postoperative complications with a high patient satisfaction score. Single-incision laparoscopic hernia repair is safe and efficient simply by modifying dissection techniques (so-called “inline” and “vertical”). Comparable success can be obtained while negating the risks of bowel and vascular injuries from sharp trocars and achieving improved cosmetic results. PMID:21902942

Laparoscopic subtotal colectomy with transrectal extraction of the colon and ileorectal anastomosis.

Despite the growing acceptance of laparoscopic colon surgery, an abdominal incision is needed to remove the specimen and perform an anastomosis. Five trocars (one 12 mm and four 5 mm) were used. The video describes the technique of performing laparoscopic subtotal colectomy, laparoscopic cholecystectomy, transrectal removal of the gallbladder and the entire colon, and intracorporeal stapled ileorectal anastomosis in a 27-year-old female with colonic inertia and biliary dyskinesia. There were no intraoperative complications. The operating time was 180 min. Blood loss was 10 cc. The patient was discharged home on postoperative day 4. Laparoscopic subtotal colectomy with transrectal removal of the colon is a safe and effective procedure that can be added to the armamentarium of surgeons performing laparoscopic colon surgery. This technique may provide both an attractive way to reduce abdominal wall morbidity and a bridge to NOTES colon surgery.

The aim of this study was to estimate the effect that the expansion of laparoscopic surgery has had on global warming. Laparoscopic procedures performed in a hospital over a 10-year period were analysed. The number of CO(2) cylinders (size C) used over a 2.5-year period and the "carbon footprint" of each cylinder was calculated. There was a fourfold increase of in the number of laparoscopic procedures performed over the past 10 years (n = 174-688). Median operative time for the laparoscopic procedures performed over the past 2.5-years (n = 1629) was 1.01 h (range 0.3-4.45 h) with 415 cylinders used in this period giving an operative time per cylinder of 3.96 h. Each cylinder produces only 0.0009 of tonnes of CO(2). Despite increasing frequency of the laparoscopic approach in general surgery, its impact on global warming is negligible.

Although the laparoscopic approach reduces pain associated with abdominal surgery, postoperative pain remains a problem. Ultrasound-guided rectus sheath block and transversus abdominis plane block have become increasingly popular means of providing analgesia for laparoscopic surgery. Ninety patients were enrolled in this study. A laparoscopic puncture needle was inserted via the port, and levobupivacaine was injected into the correct plane through the peritoneum. The patients' postoperative pain intensity was assessed using a numeric rating scale. The effects of laparoscopic nerve block versus percutaneous anesthesia were compared. This novel form of transperitoneal anesthesia did not jeopardize completion of the operative procedures. The percutaneous approach required more time for performance of the procedure than the transperitoneal technique. This new analgesia technique can become an optional postoperative treatment regimen for various laparoscopic abdominal surgeries. What we mainly want to suggest is that the transperitoneal approach has the advantage of a higher completion rate. A percutaneous technique is sometimes difficult with patients who have severe obesity and/or coagulation disorders. Additional studies are required to evaluate its benefits. Copyright © 2017.

Inguinal hernia remains the most commonly encountered surgical problem. Various methods of repair have been described, and the most suitable one debated. Single port access (SPA) surgery is a rapidly evolving field, and has the advantage of affording 'scarless' surgery. Single incision laparoscopic surgery (SILS) for inguinal hernia repair is seen to be feasible in both total extraperitoneal (TEP) and transabdominal pre-peritoneal (TAPP) approaches. Data and peri-operative information on both of these however are limited. We aimed to review the clinical experience, feasibility and short term complications related to laparoscopic inguinal hernia repair via single port access. A literature search was performed using Google Scholar, Springerlink Library, Highwire Press, Surgical Endoscopy Journal, World Journal of Surgery and Medscape. The following search terms were used: laparoscopic hernia repair, TAPP, TEP, single incision laparoscopic surgery (SILS). Fourteen articles in English language related to SILS inguinal hernia repair were identified. Nine articles were related to TEP repair and the remaining 5 to TAPP. A total of 340 patients were reported within these studies: 294 patients having a TEP repair and 46 a TAPP. Only two cases of recurrence were reported. Various ports have been utilized, including the SILS port, Tri-Port and a custom- made port using conventional laparoscopic instruments. The duration of surgery was 40-100 minutes and the average length of hospital stay was one day. Early outcomes of this novel technique show it to be feasible, safe and with potentially better cosmetic outcome.

[Progress of the laparoscopic colorectal surgery with special consideration regarding cancer treatment].

Buchmann, P; Dinçler, S

2006-04-26

The development of laparoscopic surgery began with the diagnostic coelioscopy in 1901 and the first appendectomy in 1983. Its worldwide spread started in 1987 with the cholecystectomy. Four years later the right hemicolectomy and sigmoid resection were also described. The initial euphoria however evaporated when the first reports of port-site-metastasis appeared. The controversy whether one should be allowed or not to operate carcinomas laparoscopically, provoked a boom in research with as result that in 2000 it had been confirmed that the incidence of port-site-metastasis was about the same as drain-site-metastasis after open procedures (0.9%). Randomized studies comparing laparoscopic interventions and open surgery showed no difference in the long-term results of colon-carcinoma. For experienced surgeons this is also the case for rectum-carcinoma. Hereby the learning curve is of great importance and has been put at 30 to 70 procedures, taken into account the duration of the operation or other criteria such as conversion to open surgery and complications. With growing experience the amount of material used during an operation goes down, which results in a lower overall cost of the minimal-invasive technique compared with open surgery. In cost calculations one should also take into account the fact that the recovery time and the return to every-day life is generally quicker for patients after laparoscopic surgery while overall they also have a significant better quality of life score (SF-36) in the longer term. Currently, i.e. in 2006 the laparoscopic colorectal surgery has become an established procedure. It is thought that laparoscopic interventions give additional advantages because the immune system is less affected but this must still be confirmed through research.

Laparoscopic surgery is considered in the treatment of diverticular fistula for the possible reduction of overall morbidity and complication rate if compared to open surgery. Aim of this review is to assess the possible advantages deriving from a laparoscopic approach in the treatment of diverticular fistulas of the colon. Studies presenting at least 10 adult patients who underwent laparoscopic surgery for sigmoid diverticular fistula were reviewed. Fistula recurrence, reintervention, Hartmann's procedure or proximal diversion, conversion to laparotomy were the outcomes considered. 11 non randomized studies were included. Rates of fistula recurrence (0.8%), early reintervention (30 days) (2%) and need for Hartmann's procedure or proximal diversion (1.4%) did not show significant difference between laparoscopy and open technique. there is still concern about which surgery in complicated diverticulitis should be preferred. Laparoscopic approach has led to less postoperative pain, shorter hospital stay, faster recovery and better cosmetic results. Laparoscopic resection and primary anastomosis is a possible approach to sigmoid fistulas but its advantages in terms of lower mortality rate and postoperative stay after colon resection with primary anastomosis should be interpreted with caution. When there is firm evidence supporting it, it is likely that minimally invasive surgery should become the standard approach for diverticular fistulas, thus achieving adequate exposure and better visualization of the surgical field. The lack of RCTs, the small sample size, the heterogeneity of literature do not allow to draw statistically significant conclusions on the laparoscopic surgery for fistulas despite this approach is considered safe.

2015-01-01

AIM: To review current applications of the laparoscopic surgery while highlighting the standard procedures across different fields. METHODS: A comprehensive search was undertaken using the PubMed Advanced Search Builder. A total of 321 articles were found in this search. The following criteria had to be met for the publication to be selected: Review article, randomized controlled trials, or meta-analyses discussing the subject of laparoscopic surgery. In addition, publications were hand-searched in the Cochrane database and the high-impact journals. A total of 82 of the findings were included according to matching the inclusion criteria. Overall, 403 full-text articles were reviewed. Of these, 218 were excluded due to not matching the inclusion criteria. RESULTS: A total of 185 relevant articles were identified matching the search criteria for an overview of the current literature on the laparoscopic surgery. Articles covered the period from the first laparoscopic application through its tremendous advancement over the last several years. Overall, the biggest advantage of the procedure has been minimizing trauma to the abdominal wall compared with open surgery. In the case of cholecystectomy, fundoplication, and adrenalectomy, the procedure has become the gold standard without being proven as a superior technique over the open surgery in randomized controlled trials. Faster recovery, reduced hospital stay, and a quicker return to normal activities are the most evident advantages of the laparoscopic surgery. Positive outcomes, efficiency, a lower rate of wound infections, and reduction in the perioperative morbidity of minimally invasive procedures have been shown in most indications. CONCLUSION: Improvements in surgical training and developments in instruments, imaging, and surgical techniques have greatly increased safety and feasibility of the laparoscopic surgical procedures.

It is considered that laparoscopic single-site surgery should be performed by specially trained surgeons because of the technical difficulty in using special instruments through limited access. We investigated suitable patients for single-port laparoscopic radical nephrectomy, focusing on the anatomy and distribution of the renal artery and vein. This retrospective study was conducted in 52 consecutive patients who underwent single-port radical nephrectomy by the transperitoneal approach. In patients undergoing right nephrectomy, a 2-mm port was added for liver retraction. We retrospectively re-evaluated all of the recorded surgical videos and preoperative computed tomography images. The pneumoperitoneum time (PT) was used as an objective index of surgical difficulty. The PT was significantly shorter for right nephrectomy than left nephrectomy (94 vs. 123 min, P = 0.004). With left nephrectomy, dissection of the spleno-renal ligament to mobilize the spleen medially required additional time. Also, the left renal vein could only be divided after securing the adrenal, gonadal and lumbar veins. In patients whose renal artery was located cranial to the renal vein, PT tended to be longer than in the other patients (131 vs. 108 min, P = 0.070). In patients with a superior renal artery, the inferior renal vein invariably covered the artery and made it difficult to ligate the renal artery via the umbilical approach at the first procedure. These findings indicate that patients undergoing right nephrectomy in whom the renal artery is not located cranial to the renal vein are suitable for single-port laparoscopic radical nephrectomy. © The Author 2017.

To evaluate the impact of superior rectal artery (SRA) sparing technique on anastomotic leakage in laparoscopic sigmoidectomy for diverticular disease. A retrospective multicenter analysis of all patients undergoing laparoscopic sigmoid resection for diverticular disease between 2002 and 2015 was conducted. Data were recorded in three hospitals: University Hospital Regensburg, Marienhospital Gelsenkirchen, and Städtisches Klinikum München Bogenhausen. The SRA was resected between 2002 and 2005. Since 2005, the artery was preserved in most cases. Two hundred sixty-seven patients were included. One hundred sixty patients presented with complicated diverticulitis (60%). The SRA was resected in 102 patients (group 1) and preserved in 157 patients (group 2, no data in eight cases). Anastomotic leakage occurred in 7% of patients in group 1 and 1.9% of patients in group 2 (p = 0.053). Duration of surgery was significantly shorter (157 vs. 183 min, p < 0.001) in group 2 patients. Length of hospital stay was without significant difference (group 1 8.2 days; group 2 8.3 days; p = 0.83). The conversion rate was higher in group 2 patients; however, the difference was not statistically significant (9 vs. 3%, p = 0.07). There was no significant difference between both groups regarding intraoperative complications and overall complication rate. The length of the resected specimen (19 vs. 21 cm, p = 0.001) was significantly shorter in group 2 patients. Preservation of the SRA seems to be associated with favorable outcome in patients undergoing laparoscopic sigmoid resection for diverticular disease.

Introduction Perioperative procedures are stressful and lead to haemodynamic instability with potentially devastating consequences. Dexmedetomidine is found to have many of the desired characteristics that are required in perioperative period. Aim To evaluate the ability of pre and intraoperative dexmedetomidine to attenuate stress induced haemodynamic responses, quantifying the anaesthetic agents sparing as well as its cost-effectiveness in patients undergoing laparoscopic cholecystectomy. Materials and Methods The present single blind randomized study was conducted with 120 ASA I and II consented patients who underwent laparoscopic cholecystectomy. Patients were randomly divided into 2 groups (i.e., group D and group N). Prior to induction, group D received 1 μg/kg of Dexmedetomidine and group N received Normal saline infusion over 20 minutes. Group D also received maintenance Dexmedetomidine intraoperatively. Bispectral index and minimum alveolar concentration monitoring was done in both the groups. Haemodynamic parameters were noted till 100 minutes post laryngoscopy. Opioid and anaesthetic agent consumptions were also noted and cost analysis was done. Medcalc–Version 12.5.0.0 software was used for statistics and p <0.05 was considered significant. Results Dexmedetomidine attenuated the stress induced haemodynamics responses and produced stable, relatively non fluctuating haemodynamics throughout. The Minimum Alveolar Concentration (MAC) requirement and the consumptions of Fentanyl and Isoflurane were significantly less in the Dexmedetomidine group (p<0.0001). However, despite anaesthetic dose sparing effect the anaesthetic technique was not cost-effective. Conclusion Dexmedetomidine is effective in attenuating haemodynamic responses in laparoscopic surgery and having dose sparing effect on Fentanyl, Propofol and Isoflurane. However, overall this technique is not cost-effective. PMID:28050479

Past, Present, and Future of Minimally Invasive Abdominal Surgery

Laparoscopic surgery has generated a revolution in operative medicine during the past few decades. Although strongly criticized during its early years, minimization of surgical trauma and the benefits of minimization to the patient have been brought to our attention through the efforts and vision of a few pioneers in the recent history of medicine. The German gynecologist Kurt Semm (1927–2003) transformed the use of laparoscopy for diagnostic purposes into a modern therapeutic surgical concept, having performed the first laparoscopic appendectomy, inspiring Erich Mühe and many other surgeons around the world to perform a wide spectrum of procedures by minimally invasive means. Laparoscopic cholecystectomy soon became the gold standard, and various laparoscopic procedures are now preferred over open approaches, in the light of emerging evidence that demonstrates less operative stress, reduced pain, and shorter convalescence. Natural orifice transluminal endoscopic surgery (NOTES) and single-incision laparoscopic surgery (SILS) may be considered further steps toward minimization of surgical trauma, although these methods have not yet been standardized. Laparoscopic surgery with the use of a robotic platform constitutes a promising field of investigation. New technologies are to be considered under the prism of the history of surgery; they seem to be a step toward further minimization of surgical trauma, but not definite therapeutic modalities. Patient safety and medical ethics must be the cornerstone of future investigation and implementation of new techniques. PMID:26508823

To examine bowel wall edema development in laparoscopic and open major visceral surgery. In a prospective study, 47 consecutively operated patients with gastric and pancreatic resections were included. Twenty-seven patients were operated in a conventional open procedure (open group) and 20 in a laparoscopic fashion (lap group). In all procedures, a small jejunal segment was resected during standard preparation, of which we measured the dry-wet ratio. Furthermore, HE staining was performed for measuring of bowel wall thickness and edema assessment. Mean value (±std) of dry-wet ratio was significantly lower in the open than in the lap group (0.169 ± 0.017 versus 0.179 ± 0.015; p = 0.03) with the same amount of fluid administration in both groups and a longer infusion interval during laparoscopic surgery. Subgroup analyses (only pancreatic resections) still showed similar results. Histologic examination depicted a significantly larger bowel wall thickness in the open group. Laparoscopic surgery does not seem to lead to the bowel wall edema observed to occur in open surgery regardless of the degree of intravenous fluid administration, thus supporting its use even in major visceral surgery.

Robotic colorectal surgery is being increasingly adopted. Our objective was to compare early postoperative outcomes between robotic and laparoscopic colectomy in a nationally representative sample. The American College of Surgeons National Surgical Quality Improvement Project Colectomy Targeted Dataset from 2012 to 2014 was used for this study. Adult patients undergoing elective colectomy with an anastomosis were included. Patients were stratified based on location of colorectal resection (low anterior resection (LAR), left-sided resection, or right-sided resection). Bivariate data analysis was performed, and logistic regression modeling was conducted to calculate risk-adjusted 30-day outcomes. There were a total of 25,998 laparoscopic colectomies (30 % LAR's, 45 % left-sided, and 25 % right-sided) and 1484 robotic colectomies (54 % LAR's, 28 % left-sided, and 18 % right-sided). The risk-adjusted overall morbidity, serious morbidity, and mortality were similar between laparoscopic and robotic approaches in all anastomotic groups. Patients undergoing robotic LAR had a lower conversion rate (OR 0.47, 95 % CI 1.20-1.76) and postoperative sepsis rate (OR 0.49, 95 % CI 0.29-0.85) but a higher rate of diverting ostomies (OR 1.45, 95 % CI 1.20-1.76). Robotic right-sided colectomies had significantly lower conversion rates (OR 0.58, 95 % CI 0.34-0.96). Robotic colectomy in all groups was associated with a longer operative time (by 40 min) and a decreased length of stay (by 0.5 days). In a nationally representative sample comparing laparoscopic and robotic colectomies, the overall morbidity, serious morbidity, and mortality between groups are similar while length of stay was shorter by 0.5 days in the robotic colectomy group. Robotic LAR was associated with lower conversion rates and lower septic complications. However, robotic LAR is also associated with a significantly higher rate of diverting ostomy. The reason for this relationship is unclear. Surgeon factors, patient factors, and technical factors should be considered in future studies.

Instructive laparoscopy videos with appropriate exposition could be ideal for initial training in laparoscopic surgery, but unfortunately there are no guidelines for annotating these videos or agreed methods to measure the educational content and the safety of the procedure presented. Aim of this study is to systematically search the World Wide Web to determine the availability of laparoscopic colorectal surgery videos and to objectively establish their potential training value. A search for laparoscopic right hemicolectomy videos was performed on the three most used English language web search engines Google.com, Bing.com, and Yahoo.com; moreover, a survey among 25 local trainees was performed to identify additional websites for inclusion. All laparoscopic right hemicolectomy videos with an English language title were included. Videos of open surgery, single incision laparoscopic surgery, robotic, and hand-assisted surgery were excluded. The safety of the demonstrated procedure was assessed with a validated competency assessment tool specifically designed for laparoscopic colorectal surgery and data on the educational content of the video were extracted. Thirty-one websites were identified and 182 surgical videos were included. One hundred and seventy-three videos (95%) detailed the year of publication; this demonstrated a significant increase in the number of videos published per year from 2009. Characteristics of the patient were rarely presented, only 10 videos (5.4%) reported operating time and only 6 videos (3.2%) reported 30-day morbidity; 34 videos (18.6%) underwent a peer-review process prior to publication. Formal case presentation, the presence of audio narration, the use of diagrams, and snapshots and a step-by-step approach are all characteristics of peer-reviewed videos but no significant difference was found in the safety of the procedure. Laparoscopic videos can be a useful adjunct to operative training. There is a large and increasing amount of material available for free on the internet, but this is currently unregulated.

2003-10-01

To review the feasibility of introducing advanced retroperitoneal renal laparoscopic surgery (RRLS) to a paediatric urology division, using the mentorship-training model. Although the scope of practice in paediatric urology is currently adapting endoscopic surgery into daily practice, most paediatric urologists in North America have had no formal training in laparoscopic surgery. The study included four paediatric urologists with 3-25 years of practice; none had had any formal laparoscopic training or ever undertaken advanced RRLS. An experienced laparoscopic surgeon (the mentor) assisted the learning surgeons over a year. The initial phases of learning incorporated detailed lectures, visualization through videotapes and 'hands-on' demonstration by the expert in the technique of the standardized steps for each type of surgery. Over 10 months, ablative and reconstructive RRLS was undertaken jointly by the surgeons and the mentor. After this training the surgeons operated independently. To prevent lengthy operations, conversion to open surgery was planned if there was no significant progression after 2 h of laparoscopic surgery. Over the 10 months of mentorship, 36 RRLS procedures were undertaken in 31 patients (28 ablative and eight reconstructive). In all cases the mentored surgeons accomplished both retroperitoneal access and the creation of a working space within the cavity. The group was able to initiate ablative RRLS but the mentor undertook all the reconstructive procedures. After the mentorship period, over 10 months, 12 ablative procedures were undertaken independently, and five other attempts at RRLS failed. Although the mentored approach can successfully and safely initiate advanced RRLS in a paediatric urology division, assessing the laparoscopic practice pattern after mentorship in the same group of trainees is warranted. Ablative RRLS is easier to learn for the experienced surgeon, but reconstructive procedures, e.g. pyeloplasty, require a high degree of skill in laparoscopic technique, which may only be acquired through formal training focusing primarily on suturing techniques.

Introduction Single Incision Laparoscopic Surgery (SILS) is one of the most recent developments which have been made in the field of minimal assesses surgery. It has potential advantages of less postoperative pain and better cosmesis, but at the same time, this procedure is time consuming and it increases the cost of surgery. Aim In this study, we evaluated the feasibility, safety and potential advantages of single incision laparoscopic assisted appendectomy. Materials and Methods Single incision laparoscopic assisted appendectomy was done in 82 patients who were diagnosed with acute or chronic appendicitis. A single 10mm incision made over right lower quadrant was used for placing two 5mm trocars and appendisectomy was done as in open surgery, after delivering out the appendix from the incision. Results Mean operative time was 32.56 ± 15.5 minutes. Mean post-operative pain scores as per visual analogue scalewere 6.5, 4.2 and 1.2 on 12 hours day 1 and day 2 after surgery respectively. Mean length of hospital stay was 1.4 ± 1.2 days. Conclusion Single incision laparoscopic appendectomy is safe and feasible. PMID:27437295

Laparoscopy is considered today the highlight of modern surgery, the forerunner of the fascinating world of video and robotic surgery, both of them derived from the sophisticated areas of aeronautic industry. Remarkably, Romanian specialists keep up with the pace of worldwide technological developments, assimilating one by one each and every video endoscopic procedure. In the early 90s, the Romanian laparos-copic school was founded with the contribution of many important personalities; their activities and achievements have been an inspiration for the following generation of laparoscopic surgeons. In this last decade, the newest branch of laparoscopic surgery in our country, pediatric laparoscopy, managed to evolve from its "shy" beginnings to become an important method of improving the quality of surgical procedures, to the benefit of our "small patients". The purpose of this article is to encourage and promote minimally invasive video endoscopic surgery training, emphasizing its crucial role in the education and professional development of the next generation of pediatric surgeons, and not only. The modem concept of laparoscopic training includes experimental scientific practices, as well as the newest technical acquisitions such as virtual reality video-electronic simulation.

Laparoscopy is used increasingly to treat malignant and benign colorectal surgical diseases. However, this practice is still not offered to all patients. Many barriers halt the widespread use of laparoscopic colorectal surgery. Both surgeon's and patient's factors contribute to limit a wider use of laparoscopy in colorectal surgery. We retrospectively analyzed 408 consecutive colorectal resections in a 4-year period, to find out if a selection bias exists in using laparotomy or laparoscopy for colorectal surgical diseases, and which factors are associated with a poor use of laparoscopy or to a preferred laparotomy. In our practice, advanced disease, American Society of Anesthesiologist class III and IV, and emergency status are all patient-related factors associated with laparotomy. Surgeon's age more than 52 years and lack of laparoscopic training are surgeon-related factors that negatively affect the chance of being operated on with the laparoscopic technique. An extensive laparoscopic colorectal training and a supporting environment, especially during the night shift, are needed to facilitate the use of laparoscopy in colorectal surgery avoiding a bias in selecting surgical candidates to one technique or another.

Epigastric hernia contiguous with the laparoscopic port site after endoscopic robotic total prostatectomy.

2018-03-23

Both laparoscopic and endoscopic robotic surgery are widely accepted for many abdominal surgeries. However, the port site for the laparoscope cannot be easily sutured without defect, particularly in the cranial end; this can result in a port-site incisional hernia and trigger the progressive thinning and stretching of the linea alba, leading to epigastric hernia. In the present case, we encountered an epigastric hernia contiguous with an incisional scar at the port site from a previous endoscopic robotic total prostatectomy. Abdominal ultrasound and CT revealed that the width of the linea alba was 30-48 mm. Previous CT images prepared before endoscopic robotic prostatectomy had shown a thinning of the linea alba. We should be aware of the possibility of epigastric hernia after laparoscopic and endoscopic robotic surgery. In laparoscopic and endoscopic robotic surgery for a high-risk patient for epigastric hernia, we should consider additional sutures cranial to the port-site incision to prevent of an epigastric hernia. © 2018 Japan Society for Endoscopic Surgery, Asia Endosurgery Task Force and John Wiley & Sons Australia, Ltd.

Conversion rate, non-planned admissions, readmissions, surgery duration and demographics. ALC was successfully performed in 80.8% of cases. LC with over-night (ON) stay accounted for 13.4% of patients. Admission was necessary in 4.6%. Mortality was 0.13%, 0.08 in ALC and 0.5% in ON LC. Readmissions occurred in 2.1%, 1.6% in ALC group, 5.4% in ON stay and 4.2% in admission group. ALC is a reliable and safe procedure. Minimization of admission rates is the key for cost-effective optimization in the management of cholelithiasis. ALC should be considered as the reference standard in gallbladder stone disease treatment. Copyright © 2011 AEC. Published by Elsevier Espana. All rights reserved.

Introduction: There have been many reports in the literature on vaginal mesh erosion as a complication of pelvic floor reconstructive surgery. Several reports describe successful surgical excision of the exposed mesh as a resolution. However, in rare cases of mesh erosion, poor surgical outcomes and multiple resection failures have been reported. We describe an innovative surgical approach to persistent vaginal mesh erosion using CO2 laser vaporization under colposcopic and laparoscopic guidance. Case Description: A 58-y-old postmenopausal woman first presented with a 3-y history of vaginal discharge and spotting after undergoing a Mentor ObTape transobturator sling (Mentor Corp, Santa Barbara, CA), for the treatment of stress urinary incontinence. Despite surgical removal of the mesh and multiple attempts at cauterization of persistent granulation tissue, her symptoms persisted. Discussion: Using a CO2 laser under colposcopic and laparoscopic guidance, we were able to safely expose and remove the remaining portion of retained mesh. To our knowledge, this is the first report describing CO2 laser vaporization as a surgical approach for the successful treatment of recurrent mesh erosion. PMID:23318081

Several studies have demonstrated skills transfer after virtual reality (VR) simulation training in laparoscopic surgery. However, the impact of VR simulation training on transfer of skills related to laparoscopic colectomy remains not investigated. The present study aimed at determining the impact of VR simulation warm-up on performance during laparoscopic colectomy in the porcine model. Fourteen residents naive to laparoscopic colectomy as surgeons were randomly assigned in block to two groups. Seven trainees completed a 2-h VR simulator training in the laparoscopic sigmoid colectomy module (study group). The remaining seven surgeons (control group) underwent no intervention. On the same day, all participants performed a sigmoid colectomy with anastomosis on a pig. All operations were video recorded. Two board-certified expert colorectal surgeons independently assessed performance during the colectomy on the swine. Examiners were blinded to group assignment. The two examiners used a previously validated clinical instrument specific to laparoscopic colectomy. The primary outcome was the generic and specific skills score values. Surgeons undergoing short-duration training on the VR simulator performed significantly better during laparoscopic colectomy on the pig regarding general and specific technical skills evaluation. The average score of generic skills was 17.2 (16.5-18) for the control group and 20.1 (16.5-22) for the study group (p = 0.002). The specific skills average score for the control group was 20.2 (19-21.5) and 24.2 (21-27.5) for the study group (p = 0.001). There was acceptable concordance (Kendall's W) regarding the video assessment of generic (W = 0.78) and specific skills (W = 0.84) between the two examiners. A single short-duration VR simulator practice positively impacted surgeons' generic and specific skills performance required to accomplish laparoscopic colectomy in the swine model.

Laparoscopic thermoablation of colorectal cancer metastases to the liver - new experience of the centre.

2012-01-01

Thermoablation of metastatic lesions in the liver is very commonplace. At present there are 3 essential techniques of access to carry out the procedure: open surgery, percutaneous technique and laparoscopic method. Percutaneous thermoablation is criticised due to the possible lack of radicalism. On the other hand, thermoablation during open surgery is a big perioperative trauma for the patient. The laparoscopic technique seems to be a compromise between the aforementioned techniques. The aim of this study was to present the technique and preliminary results of thermoablation of the liver carried out by means of the laparoscopic technique. Laparoscopic thermoablation was carried out in 4 patients with colorectal cancer metastases to the liver. In order to precisely locate the tumour and guarantee radicalism of the surgery, laparoscopic probe ultrasonography was carried out during the procedure. All the patients underwent the procedure without any difficulties. All the patients left the hospital department as soon as 3 or 4 days after the surgery. This was about 7 days earlier in comparison with the open surgery procedure, which had been carried out before. The patients required a supply of analgesics only during the first 48 hours - non-steroid anti-inflammatory drugs, which made a substantial difference between them and the patients treated with the open surgical technique. Thanks to the laparoscopic ultrasound technique one patient had an additional lesion located, which had not been described in preoperative examinations. In combination with ultrasonography, laparoscopic access, which does not have a very invasive character, seems to be relatively simple and effective to carry out the procedure of thermoablation.

Lumbar hernia is an unusual complication of the latissimus dorsi flap. Traditionally, it has always been repaired using open-surgery techniques. We present the first description of laparoscopic surgery to treat a non-complicated superior lumbar hernia resulting from the creation of an enlarged latissimus dorsi myocutaneous flap for breast reconstruction following left modified radical mastectomy. The laparoscopic approach substantially reduced the risks associated with open surgery, shortened length of hospital stay and time to recovery and obtained better cosmetic results. Laparoscopic surgery may be considered as a feasible therapeutic option for non-complicated superior lumbar hernias secondary to a latissimus dorsi muscle flap. Therapeutic, V.

The stomach may be involved by a myriad of pathologies ranging from benign aetiologies like inflammation to malignant aetiologies like carcinoma or lymphoma. Multidetector CT (MDCT) of the stomach is the first-line imaging for patients with suspected gastric pathologies. Conventionally, CT imaging had the advantage of simultaneous detection of the mural and extramural disease extent, but advances in MDCT have allowed mucosal assessment by virtual endoscopy (VE). Also, better three-dimensional (3D) post-processing techniques have enabled more robust and accurate pre-operative planning in patients undergoing gastrectomy and even predict the response to surgery for patients undergoing laparoscopic sleeve gastrectomy for weight loss. The ability of CT to obtain stomach volume (for bariatric surgery patients) and 3D VE images depends on various patient and protocol factors that are important for a radiologist to understand. We review the appropriate CT imaging protocol in the patients with suspected gastric pathologies and highlight the imaging pearls of various gastric pathologies on CT and VE. PMID:27785936

2007-01-01

Surgery is the mainstay of treatment of patients with peptic duodenal perforation. With the advent of minimal access techniques, laparoscopy is being used for the treatment of this condition. Retrospective analysis of 120 consecutive patients (mean age 44.5 years; 111 men) with duodenal ulcer perforation who had undergone laparoscopic surgery. 87 patients had history of tobacco consumption, 12 were chronic NSAID users, 72 had Helicobacter pylori infection and 36 had a co-morbid condition. The mean time to surgery from onset of symptoms was 28.4 hours. The median operating time was 46 minutes. All patients underwent laparoscopic closure of the perforation with Graham's patch omentopexy; 12 patients underwent additional definitive ulcer surgery. The morbidity rate was 7.5%; no patient needed conversion to open surgery or died. The mean postoperative hospital stay was 5.8 days. Results of laparoscopic management of perforated peptic ulcer are encouraging, with no conversion to open surgery, low morbidity and no mortality.

Since its introduction in the early 1990s, the laparoscopic cholecystectomy has become the standard surgical intervention for cholelithiasis. The laparoscopic technique is being used in an increasing number of abdominal procedures. Intestinal volvulus is a rare complication of laparoscopic procedures, such as the laparoscopic cholecystectomy. A review of the literature revealed 12 reports of this complication occurring without a clear cause. Etiologic factors that have been postulated include congenital malrotation, previous surgery, and intraoperative factors, such as pneumoperitoneum, mobilization of the bowel, and patient position. In this paper, we review the literature for this rare complication and report on a case of cecal bascule (a type of cecal volvulus) occurring following the laparoscopic cholecystectomy. Of the 12 prior reports of intestinal volvulus following laparoscopic procedures, 8 of these followed the laparoscopic cholecystectomy, of which two were cecal volvulae. This is the first reported case of a cecal bascule occurring following the laparoscopic cholecystectomy.

Laparoscopic surgery offers the advantages of minimally invasive surgery; however, pneumoperitoneum and the patient's position induce pathophysiological changes that may complicate anesthetic management. We studied the effect of clonidine and nitroglycerin on heart rate and blood pressure, if any, in association with these drugs or the procedure, as well as the effect of these drugs, if any, on end-tidal carbon dioxide pressure and intraocular pressure. Sixty patients (minimum age of 20 years and maximum age of 65 years, American Society of Anesthesiologists class I or II) undergoing laparoscopic cholecystectomy were randomized into 3 groups and given an infusion of clonidine (group I), nitroglycerin (group II), or normal saline solution (group III) after induction and before creation of pneumoperitoneum. We observed and recorded the following parameters: heart rate, mean arterial blood pressure, end-tidal carbon dioxide pressure, and intraocular pressure. The mean and standard deviation of the parameters studied during the observation period were calculated for the 3 treatment groups and compared by use of analysis of variance tests. Intragroup comparison was performed with the paired t test. The critical value of P, indicating the probability of a significant difference, was taken as < .05 for comparisons. Statistically significant differences in heart rate were observed among the various groups, whereas comparisons of mean arterial pressure, intraocular pressure, and end-tidal carbon dioxide pressure showed statistically significant differences only between groups I and III and between groups II and III. We found clonidine to be more effective than nitroglycerin at preventing changes in hemodynamic parameters and intraocular pressure induced by carbon dioxide insufflation during laparoscopic cholecystectomy. It was also found not to cause hypotension severe enough to stop the infusion and warrant treatment.

To understand the influence of frailty on postoperative outcomes for laparoscopic and open colectomy. Data were obtained from the National Surgical Quality Improvement Program (2005-2012) for patients undergoing colon resection [open colectomy (OC) and laparoscopic colectomy (LC)]. Patients were classified as non-frail (0 points), low frailty (1 point), moderate frailty (2 points), and severe frailty (≥ 3) using the Modified Frailty Index. 30-d mortality and complications were used as the primary end point and analyzed for the overall population. Complications were grouped into major and minor. Subset analysis was performed for patients undergoing colectomy (total colectomy, partial colectomy and sigmoid colectomy) and separately for patients undergoing rectal surgery (abdominoperineal resection, low anterior resection, and proctocolectomy). We analyzed the data using SAS Platform JMP Pro version 10.0.0 (SAS Institute Inc., Cary, NC, United States). A total of 94811 patients were identified; the majority underwent OC (58.7%), were white (76.9%), and non-frail (44.8%). The median age was 61.3 years. Prolonged length of stay (LOS) occurred in 4.7%, and 30-d mortality was 2.28%. Patients undergoing OC were older (61.89 ± 15.31 vs 60.55 ± 14.93) and had a higher ASA score (48.3% ASA3 vs 57.7% ASA2 in the LC group) ( P < 0.0001). Most patients were non-frail (42.5% OC vs 48% LC, P < 0.0001). Complications, prolonged LOS, and mortality were significantly more common in patients undergoing OC ( P < 0.0001). OC had a higher risk of death and complications compared to LC for all frailty scores (non-frail: OR = 4.7, and OR = 4.67; mildly frail: OR = 2.51, and OR = 2.47; moderately frail: OR = 2.94, and OR = 2.02, severely frail: OR = 2.37, and OR = 2.34, P < 0.05) and an increase in absolute mortality with increasing frailty (non-frail 0.68% OC, mildly frail 1.39%, moderately frail 3.44%, and severely frail 5.83%, P < 0.0001). LC is associated with improved outcomes. Although the odds of mortality are higher in non-frail, there is a progressive increase in mortality with increasing frailty.

A standard procedure for single-port laparoscopic adrenal surgery has not been established. We retrospectively investigated intraoperative and postoperative outcomes after laparoscopic adrenalectomy through mono port (LAMP) and conventional laparoscopic adrenalectomy to assess the feasibility of LAMP. Between March 2008 and December 2009, 22 patients underwent adrenalectomy at the Department of Surgery, Kangbuk Samsung Hospital. Twelve patients underwent conventional laparoscopic adrenalectomy and 10 patients underwent LAMP. The same surgeon performed all the surgeries. The 2 procedures were compared in terms of tumor size, operating time, time to resumption of a soft diet, length of hospital day, and postoperative complications. The 2 groups were similar in terms of tumor size (30.08 vs. 32.50 mm, P=0.796), mean operating time (112.9 vs. 127 min, P=0.316), time to resumption of a soft diet (1.25 vs. 1.30 d, P=0.805), and length of hospital day (4.08 vs. 4.50 d, P=0.447). Despite 1 patient in the LAMP group experiencing ipsilateral pleural effusion as a postoperative complication, this parameter was similar for the 2 groups (P=0.195). Perioperative mortality, blood transfusion, and conversion to open surgery did not occur. Perioperative outcomes for LAMP were similar to those for conventional laparoscopic adrenalectomy. LAMP appears to be a feasible option for adrenalectomy.

A perforated peptic ulcer can be managed laparoscopically in selected patients. The purpose of this study was to evaluate whether conversion of emergency laparoscopy is inferior to primary median laparotomy in terms of postoperative morbidity and mortality. We analyzed patients who underwent laparoscopic or open surgery for a perforated peptic ulcer at the Department of Surgery, University of Schleswig-Holstein, Campus Luebeck between January, 1996 and December, 2010. Perforations were graded according to the Boey classification, a preoperative risk-scoring system. Conversion to laparotomy was necessary in 20 of the 45 patients who underwent laparoscopic surgery (CG); therefore, laparoscopic operations were completed in 25 patients (LG). The third patient cohort comprised 139 patients who underwent primary laparotomy (OG). Overall minor morbidity was significantly lower (p = 0.048) in the LG patients than in the OG patients, whereas no significant differences were found in major morbidity and mortality, particularly between the OG and CG. Patients' suitability for laparoscopic management should be decided on according to Boey's clinical scoring system. Our findings demonstrated that conversion from laparoscopy to laparotomy was not associated with elevated postoperative morbidity or mortality versus initial laparotomy. Therefore, emergency operations may be commenced laparoscopically in selected patients, especially considering the postoperative advantages of this approach.

The management of Incarcerated Inguinal Hernia (IIH) in children is challenging and may be associated with complications. We aimed to compare the outcomes of laparoscopic vs. open repair of IIH. With institutional ethical approval (09SG13), we reviewed the notes of 63 consecutive children who were admitted to a single hospital with the diagnosis of IIH between 2000 and 2008. Data are reported as median (range). Groups were compared by chi-squared or t-tests as appropriate. · Open repair (n=35): There were 21 children with right and 14 with left IIH. 2 patients also had contralateral reducible inguinal hernia. Small bowel resection was required in 2 children. · Laparoscopic repair (n=28): All children had unilateral IIH (19 right sided, 9 left sided). 15 children (54%) with no clinical evidence of contralateral hernia, had contralateral patent processus vaginalis at laparoscopy, which was also repaired. The groups were similar with regard to gender, age at surgery, history of prematurity, interval between admission and surgery, and proportion of patients with successful preoperative manual reduction. However, the duration of operation was longer in the laparoscopy group (p=0.01). Time to full feeds and length of hospital stay were similar in both groups. Postoperative follow-up was 3.5 months (1-36), which was similar in both groups. 5 patients in the group undergoing open repair had serious complications: 1 vas transaction, 1 acquired undescended testis, 2 testicular atrophy and 1 recurrence. The laparoscopic group had a single recurrence. Open repair of incarcerated inguinal hernia is associated with serious complications. The laparoscopic technique appears safe, avoids the difficult dissection of an oedematous sac in the groin, allows inspection of the reduced hernia content and permits the repair of a contralateral patent processus vaginalis if present. © Georg Thieme Verlag KG Stuttgart · New York.

BACKGROUND Long-term adhesion-related complications and incisional hernias after abdominal surgery are common and costly. There are few data on the risk of these complications after different abdominal operations. STUDY DESIGN We identified Medicare beneficiaries who underwent endovascular repair of an abdominal aortic aneurysm from 2001–2008 who presumably are not at risk for laparotomy-related complications. We identified all laparoscopic and open operations involving the abdomen, pelvis, or retroperitoneum and categorized them into 5 groups according to invasiveness. We then identified laparotomy-related complications for up to 5 years after the index operation and compared these with the baseline rate of complications in a control group of patients who did not undergo an abdominal operation. RESULTS We studied 85,663 patients, 7,513 (8.8%) of which underwent a laparotomy, including 2,783 major abdominal operations, 709 minor abdominal operations, 963 ventral hernia repairs, 493 retroperitoneal/pelvic operations, and 2,565 laparoscopic operations. Mean age was 76.7 years and 82.0% were male. Major abdominal operations carried the highest risk for adhesion-related complications (14.3% and 25.0% at 2 and 5 years compared with 4.0% and 7.8% for the control group; p < 0.001) and incisional hernias (7.8% and 12.0% compared with 0.6% and 1.2% for the control group; p < 0.001). Laparoscopic operations (4.6% and 10.7% for adhesions, 1.9% and 3.2% for incisional hernias) carried the lowest risk. CONCLUSIONS Late-onset laparotomy-related complications are frequent and their risk extends through 5 years beyond the perioperative period. With the advancement and expansion of laparoscopic techniques and its attendant lower risk for long-term complications, these results can alter the risk-to-benefit profile of various types of abdominal operations and can also strengthen the rationale for additional development of laparoscopic approaches to abdominal operations.

Laparoendoscopic single site (LESS) surgery promises improved cosmesis and possibly less pain. However, given the small series reported to date, true estimates of the advantages and possible disadvantages of LESS surgery remain unknown. This study was undertaken to evaluate the first 100 patients undergoing LESS cholecystectomy at our institution. Patients referred for cholecystectomy since November 2007 were considered for LESS cholecystectomy. Outcomes, including blood loss, operative time, complications, and length of stay, were recorded. Outcomes are compared with an uncontrolled concurrent group of patients undergoing multi-incision laparoscopic (i.e., conventional) cholecystectomy. One hundred patients with a median age of 44 years underwent LESS cholecystectomy; 30 patients with a median age of 46 years underwent conventional cholecystectomy over the same time period. Median operative time (70 vs 66 minutes, P = 0.67, Mann-Whitney) and hospital length of stay (1 vs 1 day, P = 0.81, Mann-Whitney) were not different for patients undergoing LESS or multi-incision cholecystectomies, respectively. Five patients undergoing LESS cholecystectomy had postoperative complications: cystic duct stump leak (one), pain control issues (three), and urinary retention (one). LESS cholecystectomy is a safe and effective alternative to conventional cholecystectomy. It can be undertaken without added operative time and provides patients with minimal, if any, scarring.

Effect of a Standardized Protocol of Antibiotic Therapy on Surgical Site Infection after Laparoscopic Surgery for Complicated Appendicitis.

Park, Hyoung-Chul; Kim, Min Jeong; Lee, Bong Hwa

Although it is accepted that complicated appendicitis requires antibiotic therapy to prevent post-operative surgical infections, consensus protocols on the duration and regimens of treatment are not well established. This study aimed to compare the outcome of post-operative infectious complications in patients receiving old non-standardized and new standard antibiotic protocols, involving either 5 or 10 days of treatment, respectively. We enrolled 1,343 patients who underwent laparoscopic surgery for complicated appendicitis between January 2009 and December 2014. At the beginning of the new protocol, the patients were divided into two groups; 10 days of various antibiotic regimens (between January 2009 and June 2012, called the non-standardized protocol; n = 730) and five days of cefuroxime and metronidazole regimen (between July 2012 and December 2014; standardized protocol; n = 613). We compared the clinical outcomes, including surgical site infection (SSI) (superficial and deep organ/space infections) in the two groups. The standardized protocol group had a slightly shorter operative time (67 vs. 69 min), a shorter hospital stay (5 vs. 5.4 d), and lower medical cost (US$1,564 vs. US$1,654). Otherwise, there was no difference between the groups. No differences were found in the non-standardized and standard protocol groups with regard to the rate of superficial infection (10.3% vs. 12.7%; p = 0.488) or deep organ/space infection (2.3% vs. 2.1%; p = 0.797). In patients undergoing laparoscopic surgery for complicated appendicitis, five days of cefuroxime and metronidazole did not lead to more SSIs, and it decreased the medical costs compared with non-standardized antibiotic regimens.

Laparoscopic surgeries are known to be associated with a higher incidence of postoperative nausea and vomiting (PONV). Prophylaxis of PONV is usually achieved with a single-dose antiemetic drug administered during the surgical procedure. The aim of this study was to compare the antiemetic efficacy of two different 5-hydroxytryptamine-3 (5HT3) receptor antagonists, ondansetron and granisetron when given prophylactically to patients undergoing laparoscopic cholecystectomy. It was a randomized, double blind study, conducted in 90 patients. Patients were divided into two groups: Group A and Group B with 45 patients in each group. Patients in groupA were given 100 microgram/kg ondansetron intravenously (IV), and patients in Group B were given 40 microgram/kg granisetron. Both the drugs were diluted in 10 ml of 0.9% NaCl and were given at the end of surgery. The standard general anesthetic technique was administered to all the patients. Episodes of nausea, retching and vomiting were assessed during the first 24 hours after anesthesia. There was no statistically significant difference for demographic data and duration of surgery among the two groups (P>0.05). Evaluated nausea and vomiting scores in the first 3 hours period revealed that each of the drugs had a similar antiemetic effect (P>0.05). Between 4-12 hours also the episodes of nausea, retching as well as vomiting were statistically insignificant in both the groups. In the last 12 hours, episodes of nausea, retching and vomiting were significantly higher in ondansetron group. Granisetron, when given prophylactically, resulted in a significantly lower incidence of PONV than ondansetron in the first 24 hours.

The Nissen and Toupet fundoplications are the most commonly used techniques for surgical treatment of gastroesophageal reflux disease. To date, no population-based trend analysis has been reported examining the choice of procedure and short-term outcomes. This study was designed to analyze trends in the use of Nissen versus Toupet fundoplications, and corresponding short-term outcomes during a 10-year period between 1995 and 2004. A trend analysis was performed of 873 patients (Toupet: 254 patients, Nissen: 619 patients) prospectively enrolled in the database of the Swiss Association for Laparoscopic and Thoracoscopic Surgery. The frequency of the performed techniques remained stable during the observation period (p value for trend 0.206). The average postoperative and total length of hospital stay both significantly decreased during the 10-year period from 5.6 to 4.0 days and 6.8 to 4.8 days, respectively (both p values for trend <0.001). The average duration of surgery decreased significantly from 141 minutes to 121 minutes (p value for trend <0.001). There was a trend towards less complications in later years (2000-2004) compared to early years (1995-1999, p = 0.058). Conversion rates were significantly lower in later years compared with early years (p = 0.004). This is the first trend analysis in the literature reporting clinical outcomes of 873 prospectively enrolled patients undergoing Nissen and Toupet fundoplications during a 10-year period. The proportion of laparoscopic Nissen versus Toupet fundoplications remained stable over time, indicating that literature reports of the advantages of one procedure over the other had minimal influence on surgeons' choice of technique. Length of hospital stay, duration of surgery, morbidity, and conversion rate decreased over time, reflecting the learning curve. Clearly, patient outcomes have much improved during the 10-year observation period.

A novel treatment, chewing gum, may be non-inferior to ondansetron in inhibiting postoperative nausea and vomiting (PONV) in female patients after laparoscopic or breast surgery. In this pilot study, we tested the feasibility of a large randomized controlled trial. We randomized 94 female patients undergoing laparoscopic or breast surgery to ondansetron 4 mg i.v. or chewing gum if PONV was experienced in the postanaesthesia care unit (PACU). The primary outcome was full resolution of PONV, with non-inferiority defined as a difference between groups of <15% in a per protocol analysis. Secondary outcomes were PACU stay duration, anti-emetic rescue use, and acceptability of anti-emetic treatment. The feasibility of implementing the protocol in a larger trial was assessed. Postoperative nausea and vomiting in the PACU occurred in 13 (28%) ondansetron patients and 15 (31%) chewing gum patients (P=0.75). Three chewing gum patients could not chew gum when they developed PONV. On a per protocol basis, full resolution of PONV occurred in five of 13 (39%) ondansetron vs nine of 12 (75%) chewing gum patients [risk difference 37% (6.3-67%), P=0.07]. There was no difference in secondary outcomes between groups. Recruitment was satisfactory, the protocol was acceptable to anaesthetists and nurses, and data collection was complete. In this pilot trial, chewing gum was not inferior to ondansetron for treatment of PONV after general anaesthesia for laparoscopic or breast surgery in female patients. Our findings demonstrate the feasibility of a larger, multicentred randomized controlled trial to investigate this novel therapy.

This prospective study describes a simple method of combining laparoscopic ovariectomy and laparoscopic-assisted prophylactic gastropexy and determines the duration of surgery, complications, and long-term outcome including prevention of gastric dilatation-volvulus (GDV). Laparoscopic ovariectomy and laparoscopic-assisted gastropexy were performed on 26 sexually intact female dogs susceptible to GDV. The mean surgery time was 60.8 ± 12.4 min. No GDV episode was seen during the study period (mean follow-up: 5.2 ± 1.4 y). All dogs had an intact gastropexy attachment assessed by ultrasonography at 1 y. Post-operative complications were minor and owners were satisfied with the procedure. Combined laparoscopic ovariectomy and laparoscopic- assisted gastropexy appears to be a successful and low morbidity alternative procedure to both ovariectomy/ovariohysterectomy and gastropexy via open ventral-midline laparotomy.

To determine the incidence of internal hernias after laparoscopic colorectal surgery and evaluate the risk factors and strategies in the management of this serious complication. Two databases (MEDLINE from 1946 and Embase from 1949) were searched to mid-September 2015. The search terms included volvulus or internal hernia and laparoscopic colorectal surgery or colorectal surgery or anterior resection or laparoscopic colectomy. We found 49 and 124 articles on MEDLINE and Embase, respectively, an additional 15 articles were found on reviewing the references. After removal of duplicates, 176 abstracts were reviewed, with 33 full texts reviewed and 15 eligible for qualitative synthesis. The incidence of internal hernia after laparoscopic colorectal surgery is low (0.65%). Thirty-one patients were identified. Five cases were from two prospective studies (5/648, 0.8%), 20 cases were from seven retrospective studies (20/3165, 0.6%) and six patients were from case reports. Of the 31 identified cases, 21 were associated with left-sided resection, four with right sided resection, two with transverse colectomy, one with a subtotal colectomy and in three cases the operation was not specified. The majority of cases (64.3%) were associated with a restorative left sided resection. Nearly all cases occurred within 4 months of surgery. All patients required re-operation and reduction of the internal hernia and 35.7% of cases required a bowel resection. In 52.2% of cases, the mesenteric defect was closed at the second operation and 52.6% of cases were successfully managed laparoscopically. There were three deaths (0.08%). Mesenteric hernias are a rare but important complication of laparoscopic colorectal surgery. The evidence does not support routine closure for all cases, but selective closure of the mesenteric defect during left-sided restorative procedures in high-risk patients at the initial surgery may be considered.

The spread of laparoscopy has required surgeons to familiarize with a completely new surgical method and by today this method has clearly become of major importance in gastrointestinal surgery. The evolution of laparoscopic cholecystectomy offers many good lessons to learn for the purposes of advanced laparoscopic surgeries and surgeons may benefit from this experience in any process of introducing new minimal invasive techniques. We have made a retrospective analysis of the data of the cholecystectomies made in the 1st. Department of Surgery, Semmelweis University, right after laparoscopy had become a widely spread, routine surgical method (1994) as well as 13 years later (2007). The data have been processed using the SPSS 16.0 application package. Significance levels have been established with the chi-square probe. Within the analyzed timeframe we could clearly see a growing use of laparoscopic techniques (52.09% vs. 90.13%) with a growing number of cases (263/304), unchanged average age (approximately 53.5 years) and constant male/female ratio (75/25%). The BMI increased moderately (26.5 vs. 27.6), but the frequency of laparoscopic interventions on extremely obese patients grew (BMI: 25-30 37.93% vs. 44.39%, 30-35 13.79% vs. 20.6% 35-40 6.89% vs. 5.82% and 40 \\lt; 0% vs. 1.34%) while the postoperative hospitalization decreased dramatically from 5.9 days to 2.3. In year 1994, patients spent on the average 2.9 days in hospital after a laparoscopic surgery, while in year 2007 nearly 25% of the patients left the hospital 1 day after surgery. The duration of a laparoscopic surgery decreased from 78 minutes to 53, and the occurrence of intraoperative bleeding, gall bladder perforation and gallstone spillage also decreased. The conversion ratio increased from 2.7% to 4.9%. In 3% of the laparoscopic cholecystectomies (10 patients) only 3 ports were used during surgery. As surgeons have come to master the new technique, the previous relative and absolute pros and cons have been revised and at present 90% of cholecystectomies are made using laparoscopy. The data collected in the analysis of laparoscopic techniques can be used to research, learn and eventually introduce Natural Orifice Transluminal Endoscopic Surgery.

Using American College of Surgeons National Surgical Quality Improvement Program (NSQIP) data, we determined rates of HACs in patients undergoing major inpatient urological surgery from 2005 to 2012. Rates were stratified by procedure type and approach (open vs. laparoscopic/robotic). Multivariable logistic regression was used to determine the association between year of surgery and HACs. We identified 39,257 patients undergoing major urological surgery, of whom 2300 (5.9%) had at least one hospital acquired condition. Urinary tract infection (UTI, 2.6%) was the most common, followed by surgical site infection (SSI, 2.5%) and venous thrombotic events (VTE, 0.7%). Multivariable logistic regression analysis demonstrated that open surgical approach, diabetes, congestive heart failure, chronic obstructive pulmonary disease, weight loss, and ASA class were among the variables associated with higher likelihood of HAC. We observed a non-significant secular trend of decreasing rates of HAC from 7.4% to 5.8% HACs during the study period, which encompassed the implementation of the Hospital Acquired Condition Reduction Program. HACs occurred at a rate of 5.9% after major urological surgery, and are significantly affected by procedure type and patient health status. The rate of HAC appeared unaffected by national reduction program in this cohort. Better understanding of the factors associated with HACs is critical in developing effective reduction programs.

Transversus abdominis plane (TAP) block is a locoregional anaesthesia technique of growing interest in abdominal surgery. However, its efficacy following laparoscopic colorectal surgery is still debated. This meta-analysis aimed to assess the efficacy of TAP block after laparoscopic colorectal surgery. All comparative studies focusing on TAP block after laparoscopic colorectal surgery have been systematically identified through the MEDLINE database, reviewed and included. Meta-analysis was performed according to the Mantel-Haenszel method for random effects. End-points included postoperative opioid consumption, morbidity, time to first bowel movement and length of hospital stay. A total of 13 studies, including 7 randomized controlled trials, were included, comprising a total of 600 patients who underwent laparoscopic colorectal surgery with TAP block, compared with 762 patients without TAP block. Meta-analysis of these studies showed that TAP block was associated with a significantly reduced postoperative opioid consumption on the first day after surgery [weighted mean difference (WMD) -14.54 (-25.14; -3.94); P = 0.007] and a significantly shorter time to first bowel movement [WMD -0.53 (-0.61; -0.44); P < 0.001] but failed to show any impact on length of hospital stay [WMD -0.32 (-0.83; 0.20); P = 0.23] although no study considered length of stay as its primary outcome. Finally, TAP block was not associated with a significant increase in the postoperative overall complication rate [OR = 0.84 (0.62-1.14); P = 0.27]. Transversus abdominis plane (TAP) block in laparoscopic colorectal surgery improves postoperative opioid consumption and recovery of postoperative digestive function without any significant drawback.

Metabolic syndrome (MS) is common among morbidly obese patients undergoing bariatric surgery. The aim of this study was to assess the impact and predictors of bariatric surgery on the resolution of MS. Subjects included 286 patients [age 44.0 +/- 11.5, female 78.2%, BMI 48.7 +/- 9.4, waist circumference 139 +/- 20 cm, AST 23.5 +/- 14.9, ALT 30.0 +/- 20.1, type 2 diabetes mellitus (DM) 30.1% and MS 39.2%] who underwent bariatric surgery. Of the entire cohort, 27.3% underwent malabsorptive surgery, 55.9% underwent restrictive surgery, and 16.8% had combination restrictive-malabsorptive surgery. Mean weight loss was 33.7 +/- 20.1 kg after restrictive surgery (follow up period 298 +/- 271 days), 39.4 +/- 22.9 kg after malabsorptive surgery (follow-up period 306 +/- 290 days), and 28.3 +/- 14.1 kg after combination surgery (follow-up period 281 +/- 239 days). Regardless of the type of bariatric surgery, significant improvements were noted in MS (p values from <0.0001-0.01) as well as its components such as DM (p values from <0.0001-0.0005), waist circumference (p values <0.0001), BMI (p values <0.0001), fasting serum triglycerides (p values <0.0001 to 0.001), and fasting serum glucose (p values <0.0001). Additionally, a significant improvement in AST/ALT ratio (p value = 0.0002) was noted in those undergoing restrictive surgery. Multivariate analysis showed that patients who underwent malabsorptive bariatric procedures experienced a significantly greater percent excess weight loss than patients who underwent restrictive procedures (p value = 0.0451). Percent excess weight loss increased with longer postoperative follow-up (p value <0.0001). Weight loss after bariatric surgery is associated with a significant improvement in MS and other metabolic factors.
