Difference analysis of ambulatorization rate, pain, analgesic requirements and daily activities recovery in patients undergoing laparoscopic cholecystectomy with standard multiport access (CLMP) versus a minilaparoscopic, 3mm size, technique. 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.

Onders, Raymond P; Hallowell, Peter T

2005-03-01

The use of ultrasound cholangiography during cholecystectomy has been well described. This study was undertaken to assess the use of the umbilical port exclusively for ultrasound and to assess its employment on the use of fluoroscopy resources. In addition, we also looked at the increased use of ultrasound from 2000 to 2004. The use of imaging techniques during all cholecystectomies was analyzed from January 2000 to July 2001 for one surgeon and compared with that surgeon's present use from January 2004 to June 2004. Patient demographics, intraoperative finding, and postoperative results were reviewed. During the first study period, ultrasound was used in 29% of 189 laparoscopic cholecystectomies. During 2004, ultrasound was used in 77% of 66 laparoscopic cholecystectomies. Throughout both periods, fluoroscopy was only used during 6 laparoscopic common bile duct explorations (2.4% of all cases). There were no false-positive or -negative ultrasounds, and there were no bile duct injuries. As experience with ultrasound cholangiography increases, there is little indication for fluoroscopic cholangiography except for rare questions concerning anatomy and during therapeutic maneuvers for common bile duct stones.

This report describes the first prospective cohort study comparing transvaginal cholecystectomies (TVC) with single incision laparoscopic cholecystectomies (SILC) and four-port laparoscopic cholecystectomies (4PLC). Between May 2009 and August 2010, 14 patients underwent a TVC. These patients were compared with patients who underwent SILC (22 patients) or 4PLC (11 patients) in a concurrent, randomized, controlled trial. Demographic data, operative time, numerical pain scales, complications, and return to work were recorded. Mean age (TVC: 33.5 ± 3.0 year; SILC: 38.4 ± 3.3 year; 4PLC: 35.5 ± 4.1 year; p = 0.58) and mean BMI (TVC: 28.8 ± 1.5 kg/m(2); SILC: 31.8 ± 1 kg/m(2); 4PLC: 31.4 ± 2.2 kg/m(2); p = 0.35) were not statistically significant. However, mean operative time (TVC: 67 ± 3.9 min; SILC: 48.9 ± 2.6 min; 4PLC: 42.3 ± 3.9 min; p < 0.001) was significantly longer for TVC. Numerical pain scales showed significantly lower pain scores on POD 1 and 3 for TVC compared with SILC and 4PLC (TVC: 4.1 ± 0.5 and 2.9 ± 0.7; SILC: 6.1 ± 0.5 and 5.3 ± 0.5; 4PLC: 5.7 ± 0.4 and 4.7 ± 0.3; p = 0.02) with equilibration of pain scores by days 14 and 30. Return to work (TVC: 6.4 ± 1.5 days; SILC: 13.1 ± 1.3 days; 4PLC: 14.1 ± 1.4 days; p < 0.001) also was significantly faster for patients in the TVC group. One conversion in the TVC group to a 4PLC was necessary due to adhesions within the pelvis. One dislodged IUD was seen and immediately replaced in the TVC group. One hernia was observed in the SILC group. Transvaginal cholecystectomy is a safe and well-tolerated procedure with statistically significantly less pain at 1 and 3 days after surgery, with a faster return to work but longer operative times compared with single incision and four-port laparoscopic cholecystectomy.

Endoscopic retrograde cholangiopancreatography followed by laparoscopic cholecystectomy is often used as definitive treatment for common bile duct stones. The aim of this study was to investigate the optimal time interval between endoscopic retrograde cholangiopancreatography and laparoscopic cholecystectomy. PubMed and Embase were searched for studies comparing different time delays between endoscopic retrograde cholangiopancreatography and laparoscopic cholecystectomy. Observational studies and randomized controlled trials were included. Primary outcome was conversion rate from laparoscopic to open cholecystectomy and secondary outcomes were complications, mortality, operating time, and length of stay. A total of 14 studies with a total of 1930 patients were included. The pooled estimate revealed an increase from a 4.2% conversion rate when laparoscopic cholecystectomy was performed within 24 h of endoscopic retrograde cholangiopancreatography to 7.6% for 24-72 h delay to 12.3% when performed within 2 weeks, to 12.3% for 2-6 weeks, and to a 14% conversion rate when operation was delayed more than 6 weeks. According to this systematic review, it is preferable to perform cholecystectomy within 24 h of endoscopic retrograde cholangiopancreatography to reduce conversion rate. Early laparoscopic cholecystectomy does not increase mortality, perioperative complications, or length of stay and on the contrary it reduces the risk of reoccurrence and progression of disease in the delay between endoscopic retrograde cholangiopancreatography and laparoscopic cholecystectomy.

[Bile duct lesions in laparoscopic cholecystectomy].

Siewert, J R; Ungeheuer, A; Feussner, H

1994-09-01

Laparoscopic cholecystectomy is both resulting in a slightly higher incidence of biliary lesions and a change of prevalence of the type of lesions. Damage to the biliary system occurs in 4 different types: The most severe case is the lesion with a structural defect of the hepatic or common bile duct with (IVa) or without (IVb) vascular injury. Tangential lesions without structural loss of the duct should be denominated as type III (IIIa with additional lesion to the vessels, type IIIb without). Type II comprehends late strictures without obvious intraoperative trauma to the duct. Type I includes immediate biliary fistulae of usually good prognosis. The increasing prevalence of structural defects of the bile ducts appears to be a peculiarity of laparoscopic cholecystectomy necessitating highly demanding operative repair. In the majority of cases, hepatico-jejunostomy or even intraparenchymatous anastomoses are required. Adaptation of well proven principles of open surgery is the best prevention of biliary lesions in laparoscopic cholecystectomy as well as the readiness to convert early to the open procedure.

Background: Acute cholecystitis is the major complication of biliary lithiasis, for which laparoscopic treatment has been established as the standard therapy. With longer life expectancy, acute cholecystitis has often been seen in elderly patients (>65 years old) and is often accompanied by comorbity and severe complications. We sought to compare the outcome of laparoscopic treatment for acute cholecystitis with special focus on comparison between elderly and nonelderly patients. Method: This study was a prospective analysis of 190 patients who underwent laparoscopic cholecystectomy due to acute cholecystitis or chronic acute cholecystitis, comparing elderly and nonelderly patients. Results: Of 190 patients, 39 (21%) were elderly (>65 years old) and 151 (79%) were not elderly (≤65 years), with conversion rates of 10.3% and 6.6% (P=0.49), respectively. The incidence of postoperative complications in elderly and nonelderly patients were the following, respectively: atelectasis 5.1% and 2.0% (P=0.27); respiratory infection 5.1% and 2.7% (P=0.6); bile leakage 5.1% and 2.0% (P=0.27), and intraabdominal abscess 1 case (0.7%) and no incidence (P=1). Conclusion: According to our data, laparoscopic cholecystectomy is a safe and efficient procedure for the treatment of acute cholecystitis in patients older than 65 years of age. PMID:17575761

Laparoscopic Cholecystectomy and Incidental Carcinoma of the Extrahepatic Biliary Tree

Background and Objectives: Gallbladder carcinoma is found in 0.2 % to 5% of patients undergoing cholecystectomy, and gallstones are found in 70% to 98% of patients with gallbladder carcinoma. Early diagnosis of carcinoma is difficult because of the absence of specific symptoms and the frequent association with chronic cholecystitis and gallstones. At present, laparoscopic cholecystectomy is the gold standard for the surgical treatment of symptomatic cholelithiasis and other benign gallbladder diseases. The aims of this study were to evaluate retrospectively the incidence of occasional and occult gallbladder carcinomas to ascertain the effect of laparoscopy on diagnosis and treatment of unexpected extrahepatic biliary tree carcinomas and to assess possible guidelines that can be taken into consideration when the problem is encountered. Methods: Clinical records of 3900 patients undergoing laparoscopic cholecystectomy were reviewed. Patients with occasional (intraoperative = Group A) or occult (postoperative = Group B) diagnosis of gallbladder or common bile duct carcinoma entered the study group. Follow-up data were obtained in June 2000. Results: A total of 14 patients (0.35%), 3 men and 11 women, mean age 60.8 years (range 37 to 73) with extra-hepatic biliary tree carcinoma were found. Occasional carcinomas occurred in 8 patients, occult carcinomas in 6. No deaths occurred in either group. The overall survival at mean follow-up of 30.5 months is 50%. Five patients are disease free, and 2 are alive with evidence of recurrence. Discussion: In 2 large series of unselected consecutive laparoscopic cholecystectomy, only 14 unsuspected malignant tumors of the extrahepatic biliary tree were found (0.35%). The limits of the preoperative workup and the difficult diagnosis of biliary tract carcinoma during laparoscopic cholecystectomy, has led to the present retrospective study and several significant recommendations.

Background and Objective: Acute gallstone pancreatitis is quite common throughout the globe. Conventionally definitive cholecystectomy has been delayed in index hospital admission. Since the last decade timing of cholecystectomy is gradually shifting towards the earlier phase of disease and currently gallstone pancreatitis is being evaluated as a further indication for laparoscopic cholecystectomy. There is also great concern regarding compliance of patients for definitive surgery due to poverty, ignorance and illiteracy in developing countries. The aim of this study was to assess the feasibility and safety of laparoscopic cholecystectomy as a definitive treatment in patients with mild and resolving gall stone pancreatitis. Methods: This was a prospective study from July 2009 to June 2012. Patients were diagnosed by clinical examination, biochemical tests, ultrasonography and contrast enhanced CT. Patients with mild form of the disease (Ranson Score ≤3) and who showed clinical improvement were offered laparoscopic cholecystectomy in index hospital admission. Those who were unfit for surgery were referred for endoscopic sphincterotomy. Common bile duct stones were excluded preoperatively. Results: A total of 38 patients were admitted with acute gallstone pancreatitis in the study period. The mean age of patients was 46.3 years with male to female ratio of 11/27. 22 (57.8%) patients were selected for laparoscopic cholecystectomy and procedure was completed successfully. Ten (26.3%) patients were referred for ERCP and endoscopic sphincterotomy and 11 (28.9%) were managed by conservative treatment and went without any definitive treatment. Mean duration of time from onset of symptoms and laparoscopic cholecystectomy was 7 days (range 4-10). Mean duration of operative time was 45 minutes and hospital stay was 7 days. There was no operative mortality. No major intra-operative or post-operative complication was recorded. two patients (9%) had minor complications

Safe dissection of Calot's Triangle is important during the performance of laparascopic cholucystectomy. The purpose of the study is to determine the frequency of demonstrable Rouviere's sulcus in patients with symptomatic gall stones and its role in safe dissection in Calot's triangle. This is a prospective descriptive study design done in Department of surgery, Kathmandu Medical College Teaching Hospital from Jan 2013 to Jan 2015. Patients who were posted for laparoscopic cholecystectomy were included. During laparoscopy, Rouviere's sulcus was noted in the operative note and classified according to following: Type I: Open type was defined as a cleft in which the right hepatic pedicle was visualized and the sulcus was opened throughout its length. Type II: if the sulcus was open only at its lateral end. Type III If the sulcus was open only at its medial end. Type IV: Fused type was defined as one in which the pedicle was not visualized.  A total of 200 patients underwent laparoscopic cholecystectomy during period of 2 years. Out of which Rouviere's sulcus was visualized in 150 patients (75 %).Type I (open type) was commoner in 54%, type II in 12%, Type III in 9% and type IV (fused type) in 25%. Rouviere's Sulcus is an important extra biliary land mark for safe dissection of Calot's triangle during laparoscopic cholecystectomy.  Rouviere's Sulcus, Laparoscopic cholecystectomy, Bile duct injury.

Laparoscopic cholecystectomy is first-line treatment for uncomplicated gallstone disease in high-income countries due to benefits such as shorter hospital stays, reduced morbidity, more rapid return to work, and lower mortality as well-being considered cost-effective. However, there persists a lack of uptake in low- and middle-income countries. Thus, there is a need to evaluate laparoscopic cholecystectomy in comparison with an open approach in these settings. A cost-effectiveness analysis was performed to evaluate laparoscopic and open cholecystectomies at Rwanda Military Hospital (RMH), a tertiary care referral hospital in Rwanda. Sensitivity and threshold analyses were performed to determine the robustness of the results. The laparoscopic and open cholecystectomy costs and effectiveness values were $2664.47 with 0.87 quality-adjusted life years (QALYs) and $2058.72 with 0.75 QALYs, respectively. The incremental cost-effectiveness ratio for laparoscopic over open cholecystectomy was $4946.18. Results are sensitive to the initial laparoscopic equipment investment and number of cases performed annually but robust to other parameters. The laparoscopic intervention is more cost-effective with investment costs less than $91,979, greater than 65 cases annually, or at willingness-to-pay (WTP) thresholds greater than $3975/QALY. At RMH, while laparoscopic cholecystectomy may be a more effective approach, it is also more expensive given the low caseload and high investment costs. At commonly accepted WTP thresholds, it is not cost-effective. However, as investment costs decrease and/or case volume increases, the laparoscopic approach may become favorable. Countries and hospitals should aspire to develop innovative, low-cost options in high volume to combat these barriers and provide laparoscopic surgery.

[Warming up with endotrainer prior to laparoscopic cholecystectomy].

Troncoso-Bacelis, Alicia; Soto-Amaro, Jaime; Ramírez-Velázquez, Carlos

Laparoscopic cholecystectomy is a safe and effective treatment and remains the gold standard in patients with benign disease. However it presents difficulties such as: the limited movement range of the instruments, the loss of depth perception, haptic feedback and the fulcrum effect. Previous training can optimize surgical performance in patients to master basic skills. Assess the effectiveness of surgeons warming up with an endotrainer before performing laparoscopic cholecystectomy. Single-blind controlled clinical trial with 16 surgeons who performed 2 laparoscopic cholecystectomies, the first according to standard practice and the second with warm-up comprising 5 MISTELS system exercises. Patient and surgeon demographics were recorded, in addition to findings and complications during and after surgery for each procedured. We found a decrease in surgical time of 76.88 (±18.87) minutes in the group that did not warm up to prior to surgery compared with 72.81 (±35.5) minutes in the group with warm-up (p=0.0196). In addition, increased bleeding occurred in the procedures performed with warm-up 31.25 (±30.85) ml compared with the group that had no warm-up 23.94 (±15.9) (p=0.0146). Performing warm up on a MISTELS system endotrainer before performing laparoscopic cholecystectomy reduces the operating time of surgery for all surgeons. Surgery bleeding increases in operations performed by surgeons with less experience in laparoscopic surgery. Copyright © 2016 Academia Mexicana de Cirugía A.C. Publicado por Masson Doyma México S.A.

1995-03-01

Introduced in 1989, laparoscopic cholecystectomy has rapidly become the treatment of choice for symptomatic gallstones. This study describes the diffusion of laparoscopic cholecystectomy among general surgeons; assesses the importance of various reasons for surgeons adopting the procedure; and examine the influence of surgeon, practice, and health care market characteristics on the timing of adoption. The data were obtained from a survey of a national sample of surgeons. Most surgeons (81%) adopted laparoscopic cholecystectomy by early 1992. More than three fourths of adopters identified the desire to keep up with the state-of-the-art and improved patient outcomes as very or extremely important reasons for adoption. Results of proportional hazards regression analysis indicate that individual surgeons' adoption behavior generally was consistent with expected utility maximization in an uncertain new technological environment. Of particular interest, fee-for-service payment and more competitive practice settings and markets were associated with earlier adoption. These findings suggest that the "technological imperative" and surgeons' perception of the relative clinical and financial advantages of laparoscopic cholecystectomy were important reasons for the rapid diffusion of laparoscopic cholecystectomy. Policies that accelerate current trends toward payment of physicians based on salary or capitation and promote the growth of multispecialty group practice could slow the diffusion of new physician-based product innovations in health care.

Knowledge and opinions regarding Medicare reimbursement for laparoscopic cholecystectomy.

Medicare, via its fee schedule, determines amount of payment to physicians for services for its beneficiaries. Because many private insurance companies base their payment schedule on Medicare rates, it is important for physicians to know the rates of commonly performed procedures. In addition, it seems that public perception is that physicians receive substantial payments for procedures. This investigation explores patient, student, resident, and surgeon knowledge and opinion of Medicare reimbursements for laparoscopic cholecystectomy. Patients, students, residents, and surgeons filled out an IRB-exempted survey. The survey included a written description of a laparoscopic cholecystectomy. All participants were asked to give their thoughts of what Medicare currently reimburses for a laparoscopic cholecystectomy ($622) and what they thought Medicare should reimburse for a laparoscopic cholecystectomy for our geographic area. There were 105 participants (47 patients, 17 medical students, 33 surgical residents, and 8 attending surgeons) in the investigation. The reported mean reimbursements of what each group thought Medicare pays were patients, $9,396; students, $3,077; residents, $800; and surgeons, $711. The reported mean reimbursements of what each group thought Medicare should pay were patients, $8,067; students, $3,971; residents, $1,444; and surgeons, $1,600. The mean reimbursements were statistically different between all groups in both the amount Medicare currently pays and the amount Medicare should pay. Most of our participants overestimated what Medicare currently pays for laparoscopic cholecystectomy. Even the mean amount reported in the attending surgeon group was greater than the actual payment. All groups felt Medicare should pay more than the current rate; however, only patients thought Medicare should pay less than they currently pay (probably because of the incorrect perception of the current fee schedule).

2014-01-01

Background: Abdominal pain and shoulder tip pain after laparoscopic cholecystectomy are distressing for the patient. Various causes of this pain are peritoneal stretching and diaphragmatic irritation by high intra-abdominal pressure caused by pneumoperitoneum . We designed a study to compare the post operative pain after laparoscopic cholecystectomy at low pressure (7-8 mm of Hg) and standard pressure technique (12-14 mm of Hg). Aim : To compare the effect of low pressure and standard pressure pneumoperitoneum in post laparoscopic cholecystectomy pain . Further to study the safety of low pressure pneumoperitoneum in laparoscopic cholecystectomy. Settings and Design: A prospective randomised double blind study. Materials and Methods: A prospective randomised double blind study was done in 100 ASA grade I & II patients. They were divided into two groups -50 each. Group A patients underwent laparoscopic cholecystectomy with low pressure pneumoperitoneum (7-8 mm Hg) while group B underwent laparoscopic cholecystectomy with standard pressure pneumoperitoneum (12-13 mm Hg). Both the groups were compared for pain intensity, analgesic requirement and complications. Statistical Analysis: Demographic data and intraoperative complications were analysed using chi-square test. Frequency of pain, intensity of pain and analgesics consumption was compared by applying ANOVA test. Results: Post-operative pain score was significantly less in low pressure group as compared to standard pressure group. Number of patients requiring rescue analgesic doses was more in standard pressure group . This was statistically significant. Also total analgesic consumption was more in standard pressure group. There was no difference in intraoperative complications. Conclusion: This study demonstrates the use of simple expedient of reducing the pressure of pneumoperitoneum to 8 mm results in reduction in both intensity and frequency of post-operative pain and hence early recovery and better outcome

CONTEXT: Spinal anaesthesia has been reported as an alternative to general anaesthesia for performing laparoscopic cholecystectomy (LC). AIMS: Study aimed to evaluate efficacy, safety and cost benefit of conducting laparoscopic cholecystectomy under spinal anaesthesia (SA) in comparison to general anaesthesia(GA) SETTINGS AND DESIGN: A prospective, randomised study conducted over a two year period at an urban, non teaching hospital. MATERIALS AND METHODS: Patients meeting inclusion criteria e randomised into two groups. Group A and Group B received general and spinal anaesthesia by standardised techniques. Both groups underwent standard four port laparoscopic cholecystectomy. Mean anaesthesia time, pneumoperitoneum time and surgery time defined primary outcome measures. Intraoperative events and post operative pain score were secondary outcome measure. STATISTICAL ANALYSIS USED: The Student t test, Pearson′s chi-square test and Fisher exact test. RESULTS: Out of 235 cases enrolled in the study, 114 cases in Group A and 110 in Group B analysed. Mean anaesthesia time appeared to be more in the GA group (49.45 vs. 40.64, P = 0.02) while pneumoperitoneum time and corresponding the total surgery time was slightly longer in the SA group. 27/117 cases who received SA experienced intraoperative events, four significant enough to convert to GA. No postoperative complications noted in either group. Pain relief significantly more in SA group in immediate post operative period (06 and 12 hours) but same as GA group at time of discharge (24 hours). No late postoperative complication or readmission noted in either group. CONCLUSION: Laparoscopic cholecystectomy done under spinal anaesthesia as a routine anaesthesia of choice is feasible and safe. Spinal anaesthesia can be recommended to be the anaesthesia technique of choice for conducting laparoscopic cholecystectomy in hospital setups in developing countries where cost factor is a major factor.

A pneumoperitoneum of 12 to 16 mm Hg is used for laparoscopic cholecystectomy. Lower pressures are claimed to be safe and effective in decreasing cardiopulmonary complications and pain. To assess the benefits and harms of low pressure pneumoperitoneum compared with standard pressure pneumoperitoneum in people undergoing laparoscopic cholecystectomy. We searched the Cochrane Central Register of Controlled Trials (CENTRAL) in The Cochrane Library, MEDLINE, EMBASE, and Science Citation Index Expanded until February 2013 to identify randomised trials,using search strategies. We considered only randomised clinical trials, irrespective of language, blinding, or publication status for inclusion in the review. Two review authors independently identified trials and independently extracted data. We calculated the risk ratio (RR), mean difference (MD), or standardised mean difference (SMD) with 95% confidence intervals (CI) using both fixed-effect and random-effects models with RevMan 5 based on available case analysis. A total of 1092 participants randomly assigned to the low pressure group (509 participants) and the standard pressure group (583 participants) in 21 trials provided information for this review on one or more outcomes. Three additional trials comparing low pressure pneumoperitoneum with standard pressure pneumoperitoneum (including 179 participants) provided no information for this review. Most of the trials included low anaesthetic risk participants undergoing elective laparoscopic cholecystectomy. One trial including 140 participants was at low risk of bias. The remaining 20 trials were at high risk of bias. The overall quality of evidence was low or very low. No mortality was reported in either the low pressure group (0/199; 0%) or the standard pressure group (0/235; 0%) in eight trials that reported mortality. One participant experienced the outcome of serious adverse events (low pressure group 1/179, 0.6%; standard pressure group 0/215, 0%; seven trials

The purpose of this study was to determine the effectiveness of laparoscopic cholecystectomy in children with biliary dyskinesia. Reports of children with an abnormal cholecystokinin (CCK)-stimulated HIDA scan between January 2001 and July 2006 who underwent laparoscopic cholecystectomy were reviewed. Postoperatively, a 23-item Likert scale, symptom questionnaire was administered to parents. Sixty-four children with chronic abdominal pain and no gallstones on ultrasound had an abnormal CCK-HIDA scan. Twenty-three children (median age, 14 years; 16 girls), with mean (SD) ejection fraction of 17% (8), underwent laparoscopic cholecystectomy and were further analyzed. Preoperatively, these children had right upper quadrant/epigastric pain (78%), nausea (52%), vomiting (43%), and generalized abdominal pain (22%) lasting for a median of 3 months (range, 1 month to 2.5 years). Median postoperative follow-up was 2.7 years. Sixteen (70%) parents completed the questionnaire. Of those who responded, 63% indicated that their children had no abdominal pain, 87% had no vomiting, and 69% had no nausea in the month preceding the questionnaire. Overall, 67% of parents indicated that their children's symptoms were completely relieved after cholecystectomy, whereas 7% indicated that the symptoms were not relieved. Laparoscopic cholecystectomy is effective in providing both short-term and long-term improvement of symptoms in children with biliary dyskinesia.

Background: Gall bladder carcinoma accounts for 98% of all the gall bladder malignancies and it is the sixth most common malignancy of the gastrointestinal tract worldwide. The incidence of incidental gall bladder carcinoma which is diagnosed during or after a laparoscopic cholecystectomy is reported to be around 0.19-3.3% in the literature. Aim: This study was aimed at detecting the incidence of gall bladder carcinomas which were diagnosed incidentally during or after laparoscopic cholecystectomies which were done for gall stone disease and cholecystitis. Materials and Methods: We analyzed the medical records of patients with symptomatic gallstone disease and acute or chronic cholecystitis, who underwent laparoscopic cholecystectomies at the Hakeem Abdul Hameed Centenary Hospital during the period from January 2007 to June 2012. Results: A total of 622 laparoscopic cholecystectomies were performed at our institute during the study period of five and a half years. In 6 (0.96%) cases, incidental carcinomas of the gallbladder were discovered. Conclusion: A laparoscopic cholecystectomy which is performed for benign gall bladder disease rarely results in a diagnosis of unexpected gallbladder cancer. The microscopic examination of the specimens, with special attention to the depth of invasion, range of the mucosal spread and the lymphovascular involvement, is critical in diagnosing the incidental malignancies as well as for the subsequent management of the cases.

Pain after laparoscopic cholecystectomy is mild to moderate in intensity. Several modalities are employed for achieving safe and effective postoperative analgesia, the benefits of which adds to the early recovery of the patients. As a part of multimodal analgesia, various approaches of Transversus abdominis plane (TAP) block has been used for management of parietal and incisional components of pain after laparoscopic cholecystectomy. This study was designed to compare the analgesic efficacy of two different approaches of ultrasound guided TAP block, i.e., Subcostal-TAP block technique with ultrasound guided Posterior-TAP block for postoperative pain management in patients undergoing laparoscopic cholecystectomy under general anaesthesia. In this double blinded randomized controlled study, consecutive nonprobability sampling was done and a total of 126 patients admitted for elective laparoscopic cholecystectomy fulfilling the inclusion criteria were selected. After induction of general anaesthesia, patients were randomized through draw method and received either ultrasound guided posterior TAP block with 0.375% bupivacaine (20ml volume) on each side of the abdomen or subcostal TAP block bilaterally with the same. Up to 24 hours postoperatively, static and dynamic numeric rating pain scores were assessed. We found statistically significant difference in mean static pain scores over 24 hours postoperatively in subcostal TAP group, suggesting improved analgesia. However, mean dynamic postoperative pain scores were comparable between the two groups. Whereas, patients in both groups were satisfied with pain management. Ultrasound guided subcostal TAP block provides better postoperative analgesia as compared to the Posterior TAP block in laparoscopic cholecystectomy. Otherwise both of the approaches improve patient outcomes towards early recovery and discharge from hospital.

Telesurgery is a form of operative videoconferencing in which a remotely located surgeon observes a procedure through a camera and provides visual and auditory feedback to the operative site. With the use of more robotic devices in laparoscopic surgery, various forms of telesurgery have been tried. We describe the first two international telesurgical, telementored, robot-assisted laparoscopic cholecystectomies performed in the world, between the Johns Hopkins Institute, Baltimore, Maryland, USA, and the National University Hospital, Singapore.

Background Iatrogenic bile duct injury remains a current complication of laparoscopic cholecystectomy. One uniform and standardized protocol, based on the “critical view of safety” concept of Strasberg, should reduce the incidence of this complication. Furthermore, owing to the rapid development of minimally invasive surgery, technicians are becoming more frequently involved. To improve communication between the operating team and technicians, standardized actions should also be defined. The aim of this study was to compare existing protocols for laparoscopic cholecystectomy from various Dutch hospitals. Methods Fifteen Dutch hospitals were contacted for evaluation of their protocols for laparoscopic cholecystectomy. All evaluated protocols were divided into six steps and were compared accordingly. Results In total, 13 hospitals responded—5 academic hospitals, 5 teaching hospitals, 3 community hospitals—of which 10 protocols were usable for comparison. Concerning the trocar positions, only minor differences were found. The concept of “critical view of safety” was represented in just one protocol. Furthermore, the order of clipping and cutting the cystic artery and duct differed. Descriptions of instruments and apparatus were also inconsistent. Conclusions Present protocols differ too much to define a universal procedure among surgeons in The Netherlands. The authors propose one (inter)national standardized protocol, including standardized actions. This uniform standardized protocol has to be officially released and recommended by national scientific associations (e.g., the Dutch Society of Surgery) or international societies (e.g., European Association for Endoscopic Surgery and Society of American Gastrointestinal and Endoscopic Surgeons). The aim is to improve patient safety and professional communication, which are necessary for new developments. PMID:18224485

Several damage-control procedures have been described in the literature in case of severe Calot's triangle inflammation and fibrosis. In this report, we describe patients who underwent laparoscopic partial cholecystectomy using an endoscopic linear stapler. Five patients with acute cholecystitis underwent laparoscopic partial cholecystectomy in our clinic between January - December 2011. All patients had severe fibrosis and inflammation of Calot's triangle. The anterior and posterior walls of the gallbladder were totally resected if possible. The gallbladder was transected at its neck or Hartmann's pouch, leaving a remnant gallbladder pouch behind. Five patients had laparoscopic partial cholecystectomy with an endoscopic linear stapler. The main symptom of all patients on admission to the emergency room was abdominal pain. The mean time for the surgical procedure was 140 minutes (range, 120-180 minutes). Inflammation and fibrosis of Calot's triangle was detected in all patients during surgery and a phlegmonous gallbladder was detected in one patient. Surgical drains were used in all patients and no biliary leakage was detected. Remnant common bile duct calculi were detected in one patient and this patient underwent endoscopic retrograde cholangiopancreatography one month after surgery. When a reliable view of Calot's triangle cannot be obtained due to severe inflammation and fibrosis during laparoscopy, laparoscopic partial cholecystectomy seems to be a safe and feasible alternative to open surgery with an acceptable morbidity rate.

Gallbladder perforation often occurs during laparoscopic cholecystectomy. The frequency and causes of gallbladder perforation as well as the relevant clinical background factors were investigated in 110 patients undergoing laparoscopic cholecystectomy. We also evaluated intraperitoneal contamination by bacteria and gallstones at the time of gallbladder perforation and investigated whether perforation caused early or late postoperative complications. Intraoperative gallbladder perforation occurred in 29 of the 110 patients (26.3%). It was caused by injury with an electric knife during dissection of the gallbladder bed, injury during gallbladder retraction with grasping forceps, injury during gallbladder extraction from the abdomen, and slippage of cystic duct clips (potentially causing bile and stone spillage). Perforation was more frequent in patients with positive bile cultures and in those with pigment stones (p < 0.02), but not in patients with cholecystitis or cystic duct obstruction. The peritoneal cavity was contaminated by bacteria in 11/29 patients (37.9%) and by spilled stones in 3/29 patients (10.3%). There was no difference in the incidence of postoperative complications between the patients with and without perforation either in the early postoperative period or during follow-up for 24-42 months. Only one patient developed abdominal pain and fever in the early postoperative period, and they were probably related to perforation. Although gallbladder perforation is sometimes unavoidable during laparoscopic cholecystectomy, the risk of severe complications appears to be minimized by early closure of perforation, retrieval of as many of the spilled stones as possible, and intraperitoneal lavage.

The aim of the study was to assess the rate of 30-d hospital readmissions after ambulatory laparoscopic cholecystectomy. The 2009 to 2011 State Ambulatory Surgery and Services and State Inpatient Databases from California, Florida, and New York were analyzed to evaluate the incidence of 30-d readmissions after laparoscopic cholecystectomy performed in outpatient settings. Hospital transfers and the principal diagnoses of hospital readmission were analyzed as secondary outcomes. Multilevel generalized mixed linear regression analyses with fixed and random effects were used to evaluate variables associated with increased likelihood of readmissions. A total of 230,745 encounters for ambulatory laparoscopic cholecystectomies performed in 890 ambulatory facilities between 2009 and 2011 in the three states were analyzed. The rate of 30-d readmission was 20.2 per 1000 discharges. The rate of direct transfers from the ambulatory surgery center to an acute care hospital was 0.6 per 1000 discharges. The most common diagnoses of readmission were surgical complications, postoperative pain, infection, and nausea or vomiting. After adjusting for comorbidities, increasing age, male sex, non-Hispanic white race/ethnicity, any nonprivate insurance type, diagnosis of acute cholecystitis, use of intraoperative cholangiography, and having the procedure performed on a weekend were significantly associated with increased odds of 30-d readmissions. This large-state data analysis reveals that the unplanned admission and readmission rates after laparoscopic cholecystectomy are very low. Some causes of readmission (e.g., pain, nausea, and vomiting) are modifiable by the intervention of surgeons and anesthesia providers. Copyright © 2017 Elsevier Inc. All rights reserved.

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

Acute gallstone pancreatitis is quite common throughout the globe. Conventionally definitive cholecystectomy has been delayed in index hospital admission. Since the last decade timing of cholecystectomy is gradually shifting towards the earlier phase of disease and currently gallstone pancreatitis is being evaluated as a further indication for laparoscopic cholecystectomy. There is also great concern regarding compliance of patients for definitive surgery due to poverty, ignorance and illiteracy in developing countries. The aim of this study was to assess the feasibility and safety of laparoscopic cholecystectomy as a definitive treatment in patients with mild and resolving gall stone pancreatitis. This was a prospective study from July 2009 to June 2012. Patients were diagnosed by clinical examination, biochemical tests, ultrasonography and contrast enhanced CT. Patients with mild form of the disease (Ranson Score ≤3) and who showed clinical improvement were offered laparoscopic cholecystectomy in index hospital admission. Those who were unfit for surgery were referred for endoscopic sphincterotomy. Common bile duct stones were excluded preoperatively. A total of 38 patients were admitted with acute gallstone pancreatitis in the study period. The mean age of patients was 46.3 years with male to female ratio of 11/27. 22 (57.8%) patients were selected for laparoscopic cholecystectomy and procedure was completed successfully. Ten (26.3%) patients were referred for ERCP and endoscopic sphincterotomy and 11 (28.9%) were managed by conservative treatment and went without any definitive treatment. Mean duration of time from onset of symptoms and laparoscopic cholecystectomy was 7 days (range 4-10). Mean duration of operative time was 45 minutes and hospital stay was 7 days. There was no operative mortality. No major intra-operative or post-operative complication was recorded. two patients (9%) had minor complications. Laparoscopic cholecystectomy can be safely

A retrospective study was conducted on 409 patients who underwent laparoscopic cholecystectomy at Teikyo University Hospital between May, 1990 and October, 1992. The operation had to be converted to an open cholecystectomy in ten of these patients because of uncontrollable bleeding from the cystic artery in one, venous bleeding due to portal hypertension in one, extensive adhesions of the omentum and the duodenum to the gallbladder in two, extensive adhesions around the gallbladder in four, and extensive adhesions between the gallbladder and the common bile duct (CBD) in two. The time taken to complete the procedure ranged from 30 to 235 min, the average time being 81 min, and the postoperative hospital stay ranged from 3 to 56 days, the average stay being 6.5 days. Eleven patients developed complications intra- or postoperatively: bile duct injury which became manifest after the operation and required laparotomy in three patients; injury to the right hemidiaphragm resulting in a right pneumothorax in one; periumbilical subcutaneous emphysema in one; mild bile leaks which resolved in a few days in two; and a severe bile leak which resolved after 6 days in one. The indications for laparoscopic cholecystectomy have widened with experience and now, CBD stones and a history of previous gastrectomy are no longer contraindications for laparoscopic cholecystectomy. Thus, it seems that laparoscopic cholecystectomy can be performed as safely as a standard cholecystectomy, provided the patients are selected properly and appropriate caution is exercised.

The concept of reducing the number of transabdominal access ports has been criticized for violating basic tenets of traditional multiport laparoscopy. Potential benefits of reduced port surgery may include decreased pain, improved cosmesis, less hernia formation, and fewer wound complications. However, technical challenges associated with these access methods have not been adequately addressed by advancement in instrumentations. We describe our initial experience with the NovaTract™ Laparoscopic Dynamic Retractor. A retrospective review of all patients who underwent two-port laparoscopic cholecystectomy between 2013 and 2014 using the NovaTract retractor was performed. The patients were equally divided into three groups (Group A, B, C) based on the order of case performed. Eighteen consecutive patients underwent successful two-port laparoscopic cholecystectomy for symptomatic cholelithiasis. Mean age was 39.9 years and mean body mass index was 28.1 kg/m(2) (range 21-39.4). Overall mean operative time was 65 minutes (range 42-105), with Group A of 70 minutes, Group B of 65 minutes, and Group C of 58 minutes (P = .58). All cases were completed laparoscopically using the retraction system, without a need for additional ports or open conversion. No intra- or postoperative complications were seen. All patients were discharged on the same day of surgery. No mortality found in this series. The NovaTract laparoscopic dynamic retractor is safe and easy to use, which is reflected by acceptable operative time for a laparoscopic cholecystectomy using only two ports. The system allows surgical approach to mimic the conventional laparoscopic techniques, while eliminating or reducing the number of retraction ports.

Single-incision laparoscopic cholecystectomy (SILC) is a promising alternative to standard multi-incision laparoscopic cholecystectomy (LC). However, generalization of SILC is still hampered by technical difficulties mainly associated with the lack of trocars used for retraction of the gallbladder. We therefore developed a modified method of SILC with the use of needle graspers (SILC-N) for optimal retraction and exposure. In addition to two trocars inserted through a single transumbilical incision, two needle ports were placed on the right subcostal and lateral abdominal wall, through which needle graspers were used for retraction of the gallbladder. Since December, 2009, 12 patients with symptomatic cholelithiasis were treated by SILC-N. SILC-N was successfully performed in all but one patient requiring a conversion to the 4-port LC with a mean operative time of 71.5 (48-107) minutes. None of the patients experienced intraoperative or postoperative complications. The transumbilical incision and pinholes for needle graspers were almost invisible on discharge. Our preliminary results suggest that SILC-N is a simple, safe and feasible technique of cholecystectomy offering similar postoperative recovery and better cosmetic outcome as compared to conventional LC.

Fasting period before surgery may change metabolic status of the patient and have influence on perioperative stress response. The aim of the study was to investigate effects of preoperative carbohydrate-rich beverage on stress response after laparoscopic cholecystectomy. Patients admitted for laparoscopic cholecystectomy were included into study and they were randomized into a group that was fed prior to surgery and in a group that was in the regime of nothing by mouth from the evening one day before surgery. Concentrations of C-reactive protein and cortisol, were measured before and subsequently up to 48 h postoperatively. Postoperative serum C-reactive protein increased significantly in both groups, but the increase was more evident in the group with fasting protocol both 24 and 48 hours postoperatively. In fed patients cortisol concentration measured in the afternoon immediately after the operation showed physiological decline. In patients with fasting protocol postoperative cortisol values rise above the values measured in the morning. Preoperative feeding has advantage over overnight fasting by reducing preoperative discomfort in patients after laparoscopic cholecystectomy. In fed patients, smaller increase in C-reactive protein and better regulation of cortisol levels are an indicator of decreased perioperative stress response.

Background After its introduction, laparoscopic cholecystectomy rapidly expanded around the world and was accepted the procedure of choice by consensus. However, analysis of evidence shows no difference regarding primary outcome measures between laparoscopic and small-incision cholecystectomy. In absence of clear clinical benefit it may be interesting to focus on the resource use associated with the available techniques, a secondary outcome measure. This study focuses on a difference in costs between laparoscopic and small-incision cholecystectomy from a societal perspective with emphasis on internal validity and generalisability Methods A blinded randomized single-centre trial was conducted in a general teaching hospital in The Netherlands. Patients with reasonable to good health diagnosed with symptomatic cholecystolithiasis scheduled for cholecystectomy were included. Patients were randomized between laparoscopic and small-incision cholecystectomy. Total costs were analyzed from a societal perspective. Results Operative costs were higher in the laparoscopic group using reusable laparoscopic instruments (difference 203 euro; 95% confidence interval 147 to 259 euro). There were no significant differences in the other direct cost categories (outpatient clinic and admittance related costs), indirect costs, and total costs. More than 60% of costs in employed patients were caused by sick leave. Conclusion Based on differences in costs, small-incision cholecystectomy seems to be the preferred operative technique over the laparoscopic technique both from a hospital and societal cost perspective. Sick leave associated with convalescence after cholecystectomy in employed patients results in considerable costs to society. Trial registration ISRCTN Register, number ISRCTN67485658. PMID:19732431

Mishra, Manjaree; Mishra, Shashi Prakash

2014-01-01

Background and Objectives: 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. Methods: 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. Results: 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. Conclusion: 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

This study was undertaken to determine whether short-term continuous epidural analgesia using morphine would relieve pain after laparoscopic cholecystectomy. The authors retrospectively reviewed the clinical data of 182 cases who had undergone a laparoscopic cholecystectomy. These cases were divided into four groups according to their anesthetic modes as follows: a control group with general anesthesia only (n = 37); group I, general anesthesia combined with one shot of epidural morphine (n = 78); and group II, general anesthesia combined with continuous epidural analgesia using morphine (IIa for 12 h (n = 33); IIb for 8 h (n = 34)). The pain score on a four-category verbal scale and the frequency of analgesic use were investigated. There were no differences in the background characteristics of the patients among the groups, except for the duration of surgery (I vs IIa; P = 0.006). The pain scores were significantly different between the control group and the other groups. The frequency of analgesic use in the control group was also significantly higher than in the other groups. A tendency toward a higher frequency of analgesic use in group I, compared with that in groups IIa and IIb, was observed. These findings thus suggest that short-term continuous epidural analgesia using morphine can effectively relieve postoperative pain after a laparoscopic cholecystectomy.

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.

Born in secret in 1987 and developed in an atmosphere of scepticism throughout 1988, laparoscopic cholecystectomy triumphed in 1989 and 1990, causing a veritable revolution in the world of general surgery. The 777 consecutive cases that are reported in this chapter reflect the spirit of these various periods. From conservatively restrictive, our indications widened to include 90% of gallstone cases. For us the sclero-atrophic gallbladder still constitutes the greatest endoscopic challenge and should be reserved for the most experienced operators. The rates for mortality (0.1%) and complications (3.3%), which include three common bile duct injuries (0.4%), are comparable to, if not better than, those for traditional cholecystectomy. The quality of recovery is markedly better: near absence of pain, short hospitalization, return to normal physical activity within 10 days, rapid return to work and preservation of the abdominal musculature in sportspeople. These advantages are unavailable to the 5.5% of patients for whom an intraoperative conversion to an open procedure is necessary. Their recovery is that of traditional cholecystectomy, which itself is far from being poor. The large multicentre studies, such as those carried out in France and Belgium recently, reporting 3708 cases, have reached identical conclusions. Laparoscopic cholecystectomy is set to become the gold standard for treatment of gallstones and is the first step towards surgical techniques of the 21st century which will be performed within the musculocutaneous envelope of the intact human body.

Comparison of economic and environmental impacts between disposable and reusable instruments used for laparoscopic cholecystectomy.

The economic and environmental effects were compared between disposable and reusable instruments used for laparoscopic cholecystectomy. Special consideration was given to the processing of reusable instruments in the Miele G 7736 CD MCU washer disinfector and the resultant cost of sterilization. The instruments frequently used in their disposable form were identified with the help of surgeons. Thus, of all the instruments used for laparoscopic cholecystectomy, the disposable and reusable versions of trocars, scissors, and Veress cannula were compared. For the case examined in this study, the performance of laparoscopic cholecystectomy with disposable instruments was 19 times more expensive that for reusable instruments. The higher cost of using disposable instruments is primarily attributable to the purchase price of the instruments. The processing of reusable instruments has little significance in terms of cost, whereas the cost for disposing of disposable instruments is the least significant factor. The number of laparoscopic cholecystectomies performed per year does not substantially influence cost. In the authors' opinion, assessment of the environmental consequences shows that reusable instruments are environmentally advantageous. Considering the upward pressure of costs in hospitals, disposable instruments should be used for laparoscopic cholecystectomy only if they offer clear advantages over reusable instruments.

Nonsurgical uses of tranexamic acid include the management of bleeding associated with leukemia, ocular bleeding, recurrent hemoptysis, menorrhagia, hereditary angioneurotic edema, and numerous other medical problems. However, there is hardly any documentation of the use of tranexamic acid in laparoscopic cholecystectomy. This study was conducted to evaluate the role of tranexamic acid in limiting blood loss in laparoscopic cholecystectomy and to evaluate the effect of blood loss on morbidity in terms of hospital stay and mortality of the patient. The study was conducted on sixty patients admitted with gallstones, candidates for laparoscopic cholecystectomy. Thirty patients received an intravenous 20 mg/kg bolus dose of tranexamic acid at induction of anesthesia (Group A), and another thirty did not receive the aforementioned drug at induction (Group B). The two groups were compared, and the data collected were entered and tabulated using Microsoft Office Excel and analyzed using appropriate statistical tests. The mean postoperative hospital stay (2.4 vs. 2.63, P = 0.4147), drain fluid hemoglobin (Hb) (0.83 vs. 0.90, P = 0.2087), drain fluid hematocrit (0.2434 vs. 0.2627, P = 0.3787), mean drain output (85 vs. 87.23, P = 0.9271), mean pulse rate at the start of surgery (74.2 vs. 75, P > 0.999), mean pulse rate 24 h after surgery (75.9 vs. 76.4, P = 0.5775), and mean change in Hb (0.240 vs. 0.266, P = 0.2502) in both the groups were not significant. There is no active role of tranexamic acid in elective laparoscopic cholecystectomy.

An ultrasound dissector especially developed for laparoscopic surgery was used during laparoscopic cholecystectomy on 34 patients. The ultrasound power, the volume of suction and irrigation could be determined individually at the generator and activated during the operation with a foot pedal. With the dissector it was possible to fragmentate, emulgate and aspirate simultaneously fat tissue as well as infected edematous structures. The cystic artery and cystic duct, small vessels, lymphatic and connective tissue were not damaged. Therefore this system seems to be excellent for the preparation of Calot's trigonum and blunt dissection of the gallbladder out of its bed, particularly in fatty, acute or chronic infected tissue. No complications were observed within the peri- and postoperative period.

The benefits of laparoscopic cholecystectomy, including rapid recovery and fewer infections, have been largely unavailable to the majority of people in developing countries. Compared to other countries, Mongolia has an extremely high incidence of gallbladder disease. In 2005, only 2% of cholecystectomies were performed laparoscopically. This is a retrospective review of the transition from open to laparoscopic cholecystectomy throughout Mongolia. A cross-sectional, retrospective review was conducted of demographic patient data, diagnosis type, and operation performed (laparoscopic versus open cholecystectomy) from 2005-2013. Trends were analyzed from 6 of the 21 provinces (aimags) throughout Mongolia, and data were culled from 7 regional diagnostic referral and treatment centers and 2 tertiary academic medical centers. The data were analyzed by individual training center and by year before being compared between rural and urban centers. We analyzed and compared 14,522 cholecystectomies (n = 4,086 [28%] men, n = 10,436 [72%] women). Men and women were similar in age (men 52.2, standard deviation 14.8; women 49.4, standard deviation 15.7) and in the percentage undergoing laparoscopic cholecystectomy (men 39%, women 42%). By 2013, 58% of gallbladders were removed laparoscopically countrywide compared with only 2% in 2005. In 2011, laparoscopic cholecystectomy surpassed open cholecystectomy as the primary method for gallbladder removal countrywide. More than 315 Mongolian health care practitioners received laparoscopic training in 19 of the country's 21 aimags (states). By 2013, 58% of cholecystectomies countrywide were performed laparoscopically, a dramatic increase over 9 years. The expansion of laparoscopic cholecystectomy has transformed the care of biliary tract disease in Mongolia despite the country's limited resources. Copyright © 2016 Elsevier Inc.

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

Steinert's disease is an intrinsic disorder of the muscle with multisystem manifestations. Myotonia may affect any muscle group, is elicited by several factors and drugs used in general anesthesia like hypnotics, sedatives and opioids. Although some authors recommend the use of regional anesthesia or combined anesthesia with low doses of opioids, the safest anesthetic technique still has to be established. We performed a continuous spinal anesthesia in a patient with Steinert's disease undergoing laparoscopic cholecystectomy using 10mg of bupivacaine 0.5% and provided ventilatory support in the perioperative period. Continuous spinal anesthesia was safely used in Steinert's disease patients but is not described for laparoscopic cholecystectomy. We reported a continuous spinal anesthesia as an appropriate technique for laparoscopic cholecystectomy and particularly valuable in Steinert's disease patients.

Despite progress in laparoscopic surgery and increasing surgical experience, the incidence of bile duct injury during laparoscopic cholecystectomy fails to fall below 0.3%-0.6% and it is still higher than those recorded in the era of open cholecystectomy. Bile duct injuries belong to the most serious complications of abdominal surgery in general and often end up with liver transplantation as the only hope for cure. We present a case of a 78-year-old jaundiced male patient who sustained common hepatic duct injury during laparoscopic cholecystectomy eight months earlier. Exploratory laparotomy, ERCP and MRCP revealed a metal clip placed just below hepatic duct confluence and causing stricture of bile duct with dilatation of bile ducts proximal to the level of stenosis (Strasberg classification type E3 injury). Repair of the injury was performed by creating termino-lateral hepaticojejunostomy between the right and left hepatic ducts and retrocolic Roux en-Y jejunal limb. By presenting this case, we wish to emphasize the importance of timely conversion and execution of intraoperative cholangiography in all cases when identification of the structures of Calot’s triangle is not clear enough. Successful treatment of bile duct injury is only possible with joint approach of radiologist, gastroenterologist and experienced hepatobiliary surgeon.

Abstract Gallbladder rupture due to blunt abdominal injury is rare. There are few reports of traumatic gallbladder injury, and it is commonly associated with other concomitant visceral injuries. Therefore, it is difficult to diagnose traumatic gallbladder rupture preoperatively when it is caused by blunt abdominal injury. We report a patient who underwent laparoscopic cholecystectomy after an exact preoperative diagnosis of traumatic gallbladder rupture. A 43-year-old man was admitted to our hospital due to blunt abdominal trauma. The day after admission, abdominal pain and ascites increased and a muscular defense sign appeared. Percutaneous drainage of the ascites was performed, and the aspirated fluid was bloody and almost pure bile. He was diagnosed with gallbladder rupture by the cholangiography using the endoscopic retrograde cholangiopancreatography technique. Laparoscopic cholecystectomy was performed safely, and he promptly recovered. If accumulated fluids contain bile, endoscopic cholangiography is useful not only to diagnose gallbladder injury but also to determine the therapeutic strategy. PMID:27462188

To analyze the outcomes of single-port laparoscopic cholecystectomy. Early and long-term postoperative period has been analyzed in 240 patients who underwent laparoscopic cholecystectomy (LCE) including 120 cases of single-port technique and 120 cases of four-port technique. Both groups were compared in surgical time, pain syndrome severity (visual analog scale), need for analgesics, postoperative complications, hospital-stay, daily activity recovery and return to physical work, patients' satisfaction of surgical results and their aesthetic effect. It was revealed that single-port LCE is associated with lower severity of postoperative pain, quick recovery of daily activity and return to physical work, high satisfaction of surgical results and their aesthetic effect compared with four-port LCE. Disadvantages of single-port LCE include longer duration of surgery, high incidence of postoperative umbilical hernia. However hernia was predominantly observed during the period of surgical technique development. Further studies to standardize, evaluate the safety and benefits of single-port LCE are necessary.

Introduction: Laparoscopic cholecystectomy (LC) is very commonly performed surgical intervention. Acute or chronic cholecystitis, adhesions due to previous upper abdomen surgeries, Mirrizi’s syndrome and obesity are common clinical conditions that can be associated with difficult cholecystectomy. In this study, we evaluated and scored the patients with difficult surgical exploration during laparoscopic cholecystectomy. Material and Method: All patients who underwent LC from 2010 to 2015 were retrospectively rewieved. According to intraoperative findings DLC cases were described and classified. Class I difficulty: Adhesion of omentum majus, transverse colon, duodenum to the fundus of the gallbladder. Class II difficulty: Adhesions in Calot’s triangle and difficulty in dissection of cystic artery and cystic duct Class III difficulty: Difficulty in dissection of gallbladder bed (scleroathrophic gallbladder, hemorrhage from liver during dissection of gallbladder, chirotic liver). Class IV difficulty: Difficulty in exploration of gallbladder due to intraabdominal adhesions including technical problems. Results: A total of 146 patients were operated with DLC. The most common difficulty type was Class I difficulty (88 patients/60.2%). Laparoscopic cholecystectomy was converted to laparotomy in 98 patients. Operation time was found to be related with conversion to open surgery (P<0.05). Wound infection rate was also statistically higher in conversion group (P<0.05). The opertion time was found to be longest with Class II difficulty. Conversion rate to open surgery was also highest with Class II difficulty group. Conclusion: Class II difficulty characterized by severe adhesions in calot’s triangle is most serious problem among all DLC cases. They have longer operation time and higher conversion rate.

A potentially serious complication of laparoscopic cholecystectomy is the inadvertent dissemination of unsuspected gallbladder carcinoma. There are increasing reports of seeding of tumor at the trocar sites following laparoscopic cholecystectomy in patients with unexpected or inapparent gallbladder carcinoma. Although the mechanism of the abdominal wall recurrence is still unclear, laparoscopic handling of the tumor, perforation of the gallbladder, and extraction of the specimen without an endobag may be risk factors for the spreading of malignant cells. The Authors report the case of late development of umbilical metastasis after laparoscopic cholecystectomy; the presence of an incisional hernia and the finding of a stone in subcutaneous tissue demonstrate the diffusion of tumor cells into subcutaneous tissue during the extraction of gallbladder. The patient underwent an excision of the metastases. She is disease free two years after surgical treatment.

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

Background: Pain associated with laparoscopic cholecystectomy is most severe during the first 24 h and the port sites are the most painful. Recent multimodal approaches target incisional pain instead of visceral pain which has led to the emergence of abdominal fascial plane blocks. This study embraces a novel combination of two independently effective fascial plane blocks, namely rectus sheath block and subcostal transversus abdominis plane (TAP) block to alleviate postoperative pain. Study Objective: The aim is to evaluate the effectiveness of the combination of rectus sheath block and subcostal TAP block, to compare its efficacy with that of subcostal TAP block alone and with conventional port site infiltration (PSI) in alleviating postoperative pain in patients undergoing laparoscopic cholecystectomy. Methodology: This prospective, randomized control, pilot study included 61 patients scheduled for elective laparoscopic cholecystectomy and distributed among three groups, namely Group 1: Combined subcostal TAP block with rectus sheath block (n = 20); Group 2: Oblique subcostal TAP block alone (n = 21); and Group 3: PSI group as an active control (n = 20). Results: Combined group had significantly lower pain scores, higher satisfaction scores, and reduced rescue analgesia both in early and late postoperative periods than the conventional PSI group. Conclusion: Ultrasound-guided combined fascial plane blocks is a novel intervention in pain management of patients undergoing laparoscopic cholecystectomy and should become the standard of care.

Objective: We aim to perform systematic reviews of the clinical effects of the abdominal wall suspension technique in laparoscopic cholecystectomy in China. Methods: We retrieved databases of literature on randomized controlled trials involving abdominal wall suspension laparoscopic cholecystectomy. Then, we conducted screenings, extracted data, and performed quality assessment and meta-analysis. Results: We analyzed 611 patients. Our analysis showed that the abdominal wall suspension group compared to the traditional group had reduced length of hospital stay (SMD = -0.91, 95% CI = -1.76~-0.06, P = 0.04), had shortened postoperative first exhaust time (SMD = -0.65, 95% CI = -1.11~-0.20, P = 0.005), and had diminished incidence of postoperative complications (P < 0.001), which decreased the cost of hospitalization. Conclusions: Application of abdominal wall suspension endoscopic technique can significantly speed up the rehabilitation of laparoscopic cholecystectomy patients; therefore, it is worthy of further research and clinical application.

Diagnosis of incidental gallbladder cancer after laparoscopic cholecystectomy: our experience

PubMed Central

2013-01-01

Background Gallbladder carcinoma is a rare high malignancy neoplasm. The incidence of intra or post-operative incidental gallbladder carcinoma diagnosis is estimated between 0,2 and 2,8%. Primary aim of our study is to evaluate incidental gallbladder carcinoma's incidence in our experience. Methods We retrospectively reviewed our Surgery Division's experience about the totality of laparoscopic cholecystectomies with post-operative histological evidence of incidental gallbladder cancer. We evaluated patients' characteristics, surgical related variables, histological response, surgivcal radicalization characteristics and surgical outcome. Results In the considered sample we observed 7 accidental gallbladder adenocarcinomas in post-operative histological examination. Pathological results were:1 pT1b N0 (G1), 2 pT2 N0 (G2), 2 pT2 N1 (G3b), 2 pT3 N1 (G3b) (Table 1). In 5 cases we performed neoplasm radicalization surgery with standard procedure revision. Two patients died before radicalization. Median global survival was 34 months. Conclusion With the increase of laparoscopic cholecystectomies both elective and urgent performed in our centre we observed also an increase of incidentally diagnosed gallbladder neoplasms. Early diagnosis, meticulous peri-operative study and accurate surgical strategy are essential factors to obtain good results in incidental gallbladder cancer. PMID:24268097

Purpose. This prospective observational study compares an innovative approach of Single-Site Multi-Port Per-umbilical Laparoscopic Endo-surgery (SSMPPLE) cholecystectomy with the gold standard—Conventional Multi-port Laparoscopic Cholecystectomy (CMLC)—to assess the feasibility and efficacy of the former. Methods. In all, 646 patients were studied. SSMPPLE cholecystectomy utilized three ports inserted through three independent mini-incisions at the umbilicus. Only the day-to-day rigid laparoscopic instruments were used in all cases. The SSMPPLE cholecystectomy group had 320 patients and the CMLC group had 326 patients. The outcomes were statistically compared. Results. SSMPPLE cholecystectomy had average operative time of 43.8 min and blood loss of 9.4 mL. Their duration of hospitalization was 1.3 days (range, 1–5). Six patients (1.9%) of this group were converted to CMLC. Eleven patients had controlled gallbladder perforations at dissection. The Visual Analogue Scores for pain on postoperative days 0 and 7, the operative time, and the scar grades were significantly better for SSMPPLE than CMLC. However, umbilical sepsis and seroma outcomes were similar. We had no bile-duct injuries or port-site hernias in this study. Conclusion. SSMPPLE cholecystectomy approach complies with the principles of laparoscopic triangulation; it seems feasible and safe method of minimally invasive cholecystectomy. Overall, it has a potential to emerge as an economically viable alternative to single-port surgery. PMID:24876955

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.

Laparoscopic cholecystectomy is a very common minimally invasive surgical procedure that may be improved by autonomous or cooperative assistance support systems. Model-based surgery with a precise definition of distinct procedural tasks (PT) of the operation was implemented and tested to depict and analyze the process of this procedure. Reliability of real-time workflow recognition in laparoscopic cholecystectomy ([Formula: see text] cases) was evaluated by continuous sensor-based data acquisition. Ten PTs were defined including begin/end preparation calots' triangle, clipping/cutting cystic artery and duct, begin/end gallbladder dissection, begin/end hemostasis, gallbladder removal, and end of operation. Data acquisition was achieved with continuous instrument detection, room/table light status, intra-abdominal pressure, table tilt, irrigation/aspiration volume and coagulation/cutting current application. Two independent observers recorded start and endpoint of each step by analysis of the sensor data. The data were cross-checked with laparoscopic video recordings serving as gold standard for PT identification. Bland-Altman analysis revealed for 95% of cases a difference of annotation results within the limits of agreement ranging from [Formula: see text]309 s (PT 7) to +368 s (PT 5). Laparoscopic video and sensor data matched to a greater or lesser extent within the different procedural tasks. In the majority of cases, the observer results exceeded those obtained from the laparoscopic video. Empirical knowledge was required to detect phase transit. A set of sensors used to monitor laparoscopic cholecystectomy procedures was sufficient to enable expert observers to reliably identify each PT. In the future, computer systems may automate the task identification process provided a more robust data inflow is available.

Magnesium sulphate attenuates arterial pressure increase during laparoscopic cholecystectomy.

Magnesium is well known to inhibit catecholamine release and attenuate vasopressin-stimulated vasoconstriction. We investigated whether i.v. magnesium sulphate attenuates the haemodynamic stress responses to pneumoperitoneum by changing neurohumoral responses during laparoscopic cholecystectomy. Thirty-two patients undergoing laparoscopic cholecystectomy were randomly assigned to two groups; a control group was given saline, and a magnesium group received magnesium sulphate 50 mg kg(-1) immediately before pneumoperitoneum. Arterial pressure, heart rate, serum magnesium, plasma renin activity (PRA), and catecholamine, cortisol, and vasopressin levels were measured. Systolic and diastolic arterial pressures were greater in the control group (P<0.05) than in the magnesium group at 10, 20, and 30 min post-pneumoperitoneum. Norepinephrine or epinephrine levels [pg ml(-1), mean (SD)] were higher in the control group than in the magnesium group at 5 [211 (37) vs 138 (18)] or 10 min [59 (19) vs 39 (9)] post-pneumoperitoneum, respectively (P<0.05). In the control group, vasopressin levels [pg ml(-1), mean (SD)] were higher compared with the magnesium group at 5 [64 (18) vs 35 (9), P<0.01] and 10 min [65 (18) vs 47 (11), P<0.05] post-pneumoperitoneum. There were no significant differences between the groups in PRA and cortisol levels. I.V. magnesium sulphate before pneumoperitoneum attenuates arterial pressure increases during laparoscopic cholecystectomy. This attenuation is apparently related to reductions in the release of catecholamine, vasopressin, or both.

The best method to ligate the arteries during laparoscopic cholecystectomy or appendectomy remains controversy. The aim of this study is to introduce a new approach during laparoscopic combined cholecystectomy and appendectomy using a monopolar electrocautery to seal the cystic and appendix arteries. We retrospectively reviewed data from 57 patients who underwent laparoscopic combined cholecystectomy and appendectomy between December 2006 and June 2016. Each laparoscopic combined cholecystectomy and appendectomy was performed by coagulating and sealing the cystic and appendix arteries. Absorbable clip or coils were then used to ligate the proximal of cystic duct and the stump of appendix. The other side of the cystic duct and appendix which subsequently were to be removed from abdomen were used titanium clips or silk ligature. Of the 57 patients, 3 patients (5.3%) were converted to open surgery due to severe abdominal adhesions or gallbladder perforation. The mean operative time was 56 minutes (range, 40-80 minutes). Mean blood loss was 12 mL (range, 5-120 mL), and the mean postoperative hospital stay was 3.0 days (range, 2-5 days). No postoperative bleeding, biliary leakage, infection, or mortality occurred. Monopolar electrocautery to seal the cystic and appendix arteries is a safe, effective, and economical surgical procedure during laparoscopic combined cholecystectomy and appendectomy. Further randomized controlled clinical trials are required to validate our findings.

Monopolar electrocautery to seal the cystic and appendix arteries is a safe, effective, and economical surgical procedure during laparoscopic combined cholecystectomy and appendectomy. Further randomized controlled clinical trials are required to validate our findings. PMID:29595660

Objective Routine fasting (12 h) is always applied before laparoscopic cholecystectomy, but prolonged preoperative fasting causes thirst, hunger, and irritability as well as dehydration, low blood glucose, insulin resistance and other adverse reactions. We assessed the safety and efficacy of a shortened preoperative fasting period in patients undergoing laparoscopic cholecystectomy. Methods We searched PubMed, Embase and Cochrane Central Register of Controlled Trials up to 20 November 2015 and selected controlled trials with a shortened fasting time before laparoscopic cholecystectomy. We assessed the results by performing a meta-analysis using a variety of outcome measures and investigated the heterogeneity by subgroup analysis. Results Eleven trials were included. Forest plots showed that a shortened fasting time reduced the operative risk and patient discomfort. A shortened fasting time also reduced postoperative nausea and vomiting as well as operative vomiting. With respect to glucose metabolism, a shortened fasting time significantly reduced abnormalities in the ratio of insulin sensitivity. The C-reactive protein concentration was also reduced by a shortened fasting time. Conclusions A shortened preoperative fasting time increases patients' postoperative comfort, improves insulin resistance, and reduces stress responses. This evidence supports the clinical application of a shortened fasting time before laparoscopic cholecystectomy.

Laparoscopic completion radical cholecystectomy for T2 gallbladder cancer.

The role of minimally invasive surgery in the surgical management of gallbladder cancer is a matter of controversy. Because of the authors' growing experience with laparoscopic liver and pancreatic surgery, they have begun offering patients laparoscopic completion partial hepatectomies of the gallbladder bed with laparoscopic hepatoduodenal lymphadenectomy. The video shows the steps needed to perform laparoscopic resection of the residual gallbladder bed, the hepatoduodenal lymph node nodes, and the residual cystic duct stump in a setting with a positive cystic stump margin. The skin and fascia around the previous extraction site are resected, and this site is used for specimen retrieval during the second operation. To date, three patients have undergone laparoscopic radical cholecystectomy with hepatoduodenal lymph node dissection for gallbladder cancer. The average number of lymph nodes retrieved was 3 (range, 1-6), and the average estimated blood loss was 117 ml (range, 50-200 ml). The average operative time was 227 min (range, 120-360 min), and the average hospital length of stay was 4 days (range, 3-5 days). No morbidity or mortality was observed during 90 days of follow-up for each patient. Although controversy exists as to the best surgical approach for gallbladder cancer diagnosed after routine laparoscopic cholecystectomy, the minimally invasive approach seems feasible and safe, even after previous hepatobiliary surgery. If the previous extraction site cannot be ascertained, all port sites can be excised locally. Larger studies are needed to determine whether the minimally invasive approach to postoperatively diagnosed early-stage gallbladder cancer has any drawbacks.

Cholecystectomy is a common procedure. Abnormalities in the anatomy of the biliary system are common but an abnormal location of the gallbladder is much rarer. Despite frequent pre-operative imaging, the aberrant location of the gallbladder is commonly discovered at surgery. This article presents a case of a patient with the gallbladder located to the left of the falciform ligament in the absence of situs inversus totalis that presented with right upper quadrant pain. A laparoscopic cholecystectomy was performed and it was noted that the cystic duct originated from the right side. The presence of a left sided gall bladder is often associated with various biliary, portal venous and other anomalies that might lead to intra-operative injuries. The spectrum of unusual positions and anatomical gallbladder abnormalities is reviewed in order to facilitate elective and emergent cholecystectomy as well as other hepatobiliary procedures. With proper identification of the anatomy, minimally invasive approaches are still considered safe.

Abdominal pain and shoulder tip pain after laparoscopic cholecystectomy are distressing for the patient. Various causes of this pain are peritoneal stretching and diaphragmatic irritation by high intra-abdominal pressure caused by pneumoperitoneum . We designed a study to compare the post operative pain after laparoscopic cholecystectomy at low pressure (7-8 mm of Hg) and standard pressure technique (12-14 mm of Hg). Aim : To compare the effect of low pressure and standard pressure pneumoperitoneum in post laparoscopic cholecystectomy pain . Further to study the safety of low pressure pneumoperitoneum in laparoscopic cholecystectomy. A prospective randomised double blind study. A prospective randomised double blind study was done in 100 ASA grade I & II patients. They were divided into two groups -50 each. Group A patients underwent laparoscopic cholecystectomy with low pressure pneumoperitoneum (7-8 mm Hg) while group B underwent laparoscopic cholecystectomy with standard pressure pneumoperitoneum (12-13 mm Hg). Both the groups were compared for pain intensity, analgesic requirement and complications. Demographic data and intraoperative complications were analysed using chi-square test. Frequency of pain, intensity of pain and analgesics consumption was compared by applying ANOVA test. Post-operative pain score was significantly less in low pressure group as compared to standard pressure group. Number of patients requiring rescue analgesic doses was more in standard pressure group . This was statistically significant. Also total analgesic consumption was more in standard pressure group. There was no difference in intraoperative complications. This study demonstrates the use of simple expedient of reducing the pressure of pneumoperitoneum to 8 mm results in reduction in both intensity and frequency of post-operative pain and hence early recovery and better outcome.This study also shows that low pressure technique is safe with comparable rate of intraoperative

Laparoscopy has become the gold standard for many abdominal procedures. Among young surgeons, experience in laparoscopic surgery increasingly outweighs experience in open surgery. This study was conducted to compare residents' performance in laparoscopic versus open bench-model task. In an international surgical skills course, we compared trainees' performance in open versus laparoscopic cholecystectomy in a cadaveric animal bench-model. Both exercises were evaluated by board-certified surgeons using an 8-item checklist and by the trainees themselves. 238 trainees with a median surgical experience of 24 months (interquartile range 14-48) took part. Twenty-two percent of the trainees had no previous laparoscopic and 62% no previous open cholecystectomy experience. Significant differences were found in the overall score (median difference of 1 (95% CI: 1, 1), p < 0.001), gallbladder perforation rate (73% vs. 29%, p < 0.001), safe dissection of the Calot's triangle (98% vs. 90%, p = 0.001) and duration of surgery (42 (13) minutes vs. 26 (10) minutes (mean differences 17.22 (95% CI: 15.37, 19.07), p < 0.001)), all favouring open surgery. The perforation rate in open and laparoscopic cholecystectomies was not consistently decreasing with increasing years of experience or number of previously performed procedures. Self-assessment was lower than the assessment by board-certified surgeons. Despite lower experience in open compared to laparoscopic cholecystectomy, better performance was observed in open task. It may be explained by a wider access with easier preparation. Open cholecystectomy is the rescue manoeuvre and therefore, it is important to provide also enough training opportunities in open surgery. Copyright © 2015 IJS Publishing Group Limited.

Bile duct injuries from laparoscopic cholecystectomy remain a significant source of morbidity and are often the result of intraoperative errors in perception, judgment, and decision-making. This qualitative study aimed to define and characterize higher-order cognitive competencies required to safely perform a laparoscopic cholecystectomy. Hierarchical and cognitive task analyses for establishing a critical view of safety during laparoscopic cholecystectomy were performed using qualitative methods to map the thoughts and practices that characterize expert performance. Experts with more than 5 years of experience, and who have performed at least 100 laparoscopic cholecystectomies, participated in semi-structured interviews and field observations. Verbal data were transcribed verbatim, supplemented with content from published literature, coded, thematically analyzed using grounded-theory by 2 independent reviewers, and synthesized into a list of items. A conceptual framework was created based on 10 interviews with experts, 9 procedures, and 18 literary sources. Experts included 6 minimally invasive surgeons, 2 hepato-pancreatico-biliary surgeons, and 2 acute care general surgeons (median years in practice, 11 [range 8 to 14]). One hundred eight cognitive elements (35 [32%] related to situation awareness, 47 [44%] involving decision-making, and 26 [24%] action-oriented subtasks) and 75 potential errors were identified and categorized into 6 general themes and 14 procedural tasks. Of the 75 potential errors, root causes were mapped to errors in situation awareness (24 [32%]), decision-making (49 [65%]), or either one (61 [81%]). This study defines the competencies that are essential to establishing a critical view of safety and avoiding bile duct injuries during laparoscopic cholecystectomy. This framework may serve as the basis for instructional design, assessment tools, and quality-control metrics to prevent injuries and promote a culture of patient safety. Copyright

The rise of elderly population is due to the improvement of life expectancy. The biliary lithiasis is the most common condition requiring intra-abdominal surgery. Half of these patients sustain associated diseases and frequently develops acute and complicated forms of cholelithiasis. Therefore, cholecystectomy is indicated for patients with chronic symptomatic disease. During a long period open cholecystectomy has been practiced, with low complications and mortality rates. Videolaparoscopy has been recently proposed as an option in these cases, however, few studies compared its advantages over open cholecystectomy for elderly patients. To access the early results of the surgical treatment for cholelithiasis in the elderly submitted to an open or laparoscopic cholecystectomy. retrospective study with 246 patients > 65 years old, who underwent elective cholecystectomy through a subcostal incision (group I) or laparoscopic approach (group II). We employed Student's t test and Spearman's correlation for statistical analysis, considering p < 0,05 as significant. A hundred and twenty patients were arranged in group I and 126 in group II. Associated diseases were present in 155 cases (63). There were no differences between the groups regarding both the distribution of comorbid conditions. Conversion was evaluated in 10 patients (8.3%). The mean operative time was 133 minutes in group I and 112 minutes in group II (p=0.001). The mean hospital stay in group I was 3,3 days and in group II was 3.2 days p=0.698. Thirteen patients in each group developed complications: group I (10.8%) and group II (10.3%) p=0,896. There was no statistis significance in complication rate related to gender, age, associated diseases and ASA when the both groups were compared. There were two deaths, both in group II, although the mortality rate was not statiscally significant between the groups (p=0.158). Both open and laparoscopic cholecystectomy can be practiced in the elderly with low and

There is conflicting evidence for the use of warmed, humidified carbon dioxide (CO2) for creating pneumoperitoneum during laparoscopic cholecystectomy. Few studies have reported less post-operative pain and analgesic requirement when warmed CO2 was used. This systematic review and meta-analysis aims to analyse the literature on the use of warmed CO2 in comparison to standard temperature CO2 during laparoscopic cholecystectomy. Systematic review and meta-analysis carried out in line with the PRISMA guidelines. Primary outcomes of interest were post-operative pain at 6 h, day 1 and day 2 following laparoscopic cholecystectomy. Secondary outcomes were analgesic usage and drop in intra-operative core body temperature. Standard Mean Difference (SMD) was calculated for continuous variables. Six randomised controlled trials (RCTs) met the inclusion criteria (n = 369). There was no significant difference in post-operative pain at 6 h [3 RCTs; SMD = -0.66 (-1.33, 0.02) (Z = 1.89) (P = 0.06)], day 1 [4 RCTs; SMD = -0.51 (-1.47, 0.44) (Z = 1.05) (P = 0.29)] and day 2 [2 RCTs; SMD = -0.96 (-2.30, 0.37) (Z = 1.42) (P = 0.16)] between the warmed CO2 and standard CO2 group. There was no difference in analgesic usage between the two groups, but pooled analysis was not possible. Two RCTs reported significant drop in intra-operative core body temperature, but there were no adverse events related to this. This review showed no difference in post-operative pain and analgesic requirements between the warmed and standard CO2 insufflation during laparoscopic cholecystectomy. Currently there is not enough high quality evidence to suggest routine usage of warmed CO2 for creating pneumoperitoneum during laparoscopic cholecystectomy.

The role of a robotic assistant in laparoscopic cholecystectomy is controversial. While some trials have shown distinct advantages of a robotic assistant over a human assistant others have not, and it is unclear which robotic assistant is best. The aims of this review are to assess the benefits and harms of a robot assistant versus human assistant or versus another robot assistant in laparoscopic cholecystectomy, and to assess whether the robot can substitute the human assistant. We searched the Cochrane Central Register of Controlled Trials (CENTRAL) in The Cochrane Library, MEDLINE, EMBASE, and Science Citation Index Expanded (until February 2012) for identifying the randomised clinical trials. Only randomised clinical trials (irrespective of language, blinding, or publication status) comparing robot assistants versus human assistants in laparoscopic cholecystectomy were considered for the review. Randomised clinical trials comparing different types of robot assistants were also considered for the review. Two authors independently identified the trials for inclusion and independently extracted the data. We calculated the risk ratio (RR) or mean difference (MD) with 95% confidence interval (CI) using the fixed-effect and the random-effects models based on intention-to-treat analysis, when possible, using Review Manager 5. We included six trials with 560 patients. One trial involving 129 patients did not state the number of patients randomised to the two groups. In the remaining five trials 431 patients were randomised, 212 to the robot assistant group and 219 to the human assistant group. All the trials were at high risk of bias. Mortality and morbidity were reported in only one trial with 40 patients. There was no mortality or morbidity in either group. Mortality and morbidity were not reported in the remaining trials. Quality of life or the proportion of patients who were discharged as day-patient laparoscopic cholecystectomy patients were not reported in any

Gall bladder carcinoma accounts for 98% of all the gall bladder malignancies and it is the sixth most common malignancy of the gastrointestinal tract worldwide. The incidence of incidental gall bladder carcinoma which is diagnosed during or after a laparoscopic cholecystectomy is reported to be around 0.19-3.3% in the literature. This study was aimed at detecting the incidence of gall bladder carcinomas which were diagnosed incidentally during or after laparoscopic cholecystectomies which were done for gall stone disease and cholecystitis. We analyzed the medical records of patients with symptomatic gallstone disease and acute or chronic cholecystitis, who underwent laparoscopic cholecystectomies at the Hakeem Abdul Hameed Centenary Hospital during the period from January 2007 to June 2012. A total of 622 laparoscopic cholecystectomies were performed at our institute during the study period of five and a half years. In 6 (0.96%) cases, incidental carcinomas of the gallbladder were discovered. A laparoscopic cholecystectomy which is performed for benign gall bladder disease rarely results in a diagnosis of unexpected gallbladder cancer. The microscopic examination of the specimens, with special attention to the depth of invasion, range of the mucosal spread and the lymphovascular involvement, is critical in diagnosing the incidental malignancies as well as for the subsequent management of the cases.

Fluorescence cholangiography during laparoscopic cholecystectomy in a patient with situs inversus totalis: a case report and literature review.

Situs inversus totalis is a rare autosomal disorder in which the patient's affected visceral organs are a perfect mirror image of their normal positions. Surgery in these patients is technically challenging. Minimally invasive surgery such as laparoscopic cholecystectomy is the standard treatment for symptomatic cholelithiasis, but it can be difficult to perform. Laparoscopic cholecystectomy in patients with situs inversus totalis may be even more technically challenging. Fluorescence cholangiography is a new innovation in the field of navigation surgery. This procedure is safe and easy to perform, its findings are easy to interpret, and it does not require a learning curve or radiographs. It can be used in real time during surgery to identify extrahepatic biliary structures. We herein report a case of situs inversus totalis in a Thai patient with a history of biliary pancreatitis. He underwent laparoscopic cholecystectomy with intraoperative fluorescence cholangiography. The operation was successfully completed without complications. To the best of our knowledge, this is the first case report of the use of fluorescence cholangiography during laparoscopic cholecystectomy in a patient with situs inversus. Fluorescence cholangiographyis a new navigational surgical technique with which to identify extrahepatic biliary structures. It can be used as an adjunct technique during laparoscopic cholecystectomy to avoid biliary tract injury in difficult cases.

Recent reports indicate that laparoscopic cholecystectomy in pregnancy is safe. The aim of this study was to evaluate whether delays in definitive treatment of symptomatic cholelithiasis increase morbidity. We reviewed the records of 16 women who underwent laparoscopic cholecystectomy during pregnancy between 1992 and 1999. Mean age was 24 +/- 5 years (mean +/- standard error). Symptom onset was during the first trimester in nine patients, second trimester in six patients, and third trimester in one patient. Patients had abdominal pain (93%), nausea (93%), emesis (80%), and fever (66%) for a median of 45 days (range 1-195 days) before cholecystectomy. Nine of 11 women who underwent cholecystectomy more than 5 weeks after onset of symptoms experienced recurrent attacks necessitating 15 hospital admissions and four emergency room visits. Moreover four women who developed symptoms in the first and second trimesters but whose operations were delayed to the third trimester had 11 hospital admissions and four emergency room visits; three of those four (75%) women developed premature contractions necessitating tocolytics. Cholecystectomy was completed laparoscopically in 14 women. There was no hospital infant or maternal mortality or morbidity. We recommend prompt laparoscopic cholecystectomy in pregnant women with symptomatic biliary disease because it is safe and it reduces hospital admissions and frequency of premature labor.

Laparoscopic cholecystectomy (LC) has traditionally been performed under general anesthesia, however, owing in part to the advancement of surgical and anesthetic techniques, many laparoscopic cholecystectomies have been successfully performed under the spinal anesthetic technique. We hoped to determine the feasibility of segmental epidural anesthesia for LC. Twelve American Society of Anesthesiologists class I or II patients received an epidural block for LC. The level of epidural block and the satisfaction score of patients and the surgeon were checked to evaluate the efficacy of epidural block for LC. LC was performed successfully under epidural block, with the exception of 1 patient who required a conversion to general anesthesia owing to severe referred pain. There were no special postoperative complications, with the exception of one case of urinary retention. Epidural anesthesia might be applicable for LC. However, the incidence of intraoperative referred shoulder pain is high, and so careful patient recruitment and management of shoulder pain should be considered.

Surgical procedure was the standard one described by Cox. The mean duration of the operation was 60 minutes and was significantly related to the surgeon's experience; the incedence of conversion to open procedure was 5.7%. There was no postoperative mortality; the total morbility rate was 2.8%, with 3 major complications, and 5 minor complications.

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

Objective: Natural orifice transluminal endoscopic surgery (NOTES) is an endoscopic technique whereby surgical interventions can be performed with a flexible endoscope passed through a natural orifice (mouth, vulva, urethra, anus) then through a transluminal opening of the stomach, vagina, bladder, or colon. Although in the early stage of research and development, NOTES has been clinically applied across the globe, above all the transvaginal cholecystectomy is among the most frequently performed procedures. In the existing 2 types of transvaginal routes, the hybrid NOTES cholecystectomy (NC) is more likely to be accepted. However, there has been controversy regarding the safety outcomes of hybrid NC in comparison with classical laparoscopic cholecystectomy (LC). The primary objective of this meta-analysis is to compare the characteristics between NC and classical LC. Materials and Methods: A meta-analysis of eligible studies comparing NC with classical LC was performed to evaluate the safety outcomes including wound complications, other postoperative complications and intraoperative conversion between the 2 groups. Results: Pooling 3 randomized controlled trials (n=157) and 7 nonrandomized trial (n=593) demonstrated that the rates of wound complications and other postoperative complications in NC group did not significantly differ from those of classical LC group [wound complications: ratio difference (RD)=−0.02, 95% confidence interval (CI) −0.04to 0.01, P=0.23; other postoperative complication: RD=−0.01; 95% CI, −0.03 to 0.02; P=0.6]. The intraoperative conversion rate in NC groups was higher than that of LC groups (RD=0.03; 95% CI, 0.01-0.06; P=0.02). Conclusions: There is no significate difference between the safety of NC and laparoscope cholecystectomy. NC is associated with a higher rate of intraoperative conversion when compared with LC. It is worthy of further promotion and validation in clinical settings. PMID:27557339

Laparoscopic upper abdominal surgery can cause spontaneous respiration due to diaphragmatic stimulation and intra-abdominal CO 2 inflation. Therefore, sufficient muscle relaxation is necessary for a safe surgical environment. We investigated if the combination of rocuronium and cisatracurium can counteract the delayed onset of cisatracurium's action and delayed recovery of muscle relaxation and whether the dosage of rocuronium, which is metabolized hepatically, can be reduced. A total of 75 patients scheduled for laparoscopic cholecystectomy with an American Society of Anesthesiology physical status I-II, in the age range of 20-60 years, and with a 20-30 kg/m 2 body mass index were included in the study. The patients were divided into the following groups: combination group (Group RC, rocuronium 0.3 mg/kg and cisatracurium 0.05 mg/kg), rocuronium group (Group R, rocuronium 0.6 mg/kg), and cisatracurium group (Group C, cisatracurium 0.1 mg/kg), and the onset, 25% duration, recovery index, and addition/time ratio were measured. Patients in Group RC exhibited a significantly different addition/time ratio compared with patients in the other two groups (p = 0.003). During laparoscopic cholecystectomy, the 95% effective dose of rocuronium in combination with cisatracurium is expected to provide a sufficient muscle relaxant effect.

Introduction. Early laparoscopic cholecystectomy is usually associated with reduced hospital stay, sick leave, and health care expenditures. Early diagnosis and treatment of acute cholecystitis reduce both mortality and morbidity and the accurate diagnosis requires specific diagnostic criteria of clinical data and imaging studies. Objectives. To compare early versus delayed laparoscopic cholecystectomy regarding the operative outcome and patient satisfaction. Patients and Methods. Patients with acute cholecystitis were divided into two groups, early (A) and delayed (B) cholecystectomy. Diagnosis of acute cholecystitis was confirmed by clinical examination, laboratory data, and ultrasound study. The primary end point was operative and postoperative outcome and the secondary was patient's satisfaction. Results. The number of readmissions in delayed treatment group B was three times in 10% of patients, twice in 23.3%, and once in 66.7% while the number of readmissions was once only in patients in group A and the mean total hospital stays were higher in group B than in group A. The overall patient's satisfaction was 92.66 ± 6.8 in group A compared with 75.34 ± 12.85 in group B. Conclusion. Early laparoscopic cholecystectomy resulted in significant reduction in length of hospital stay and accepted rate of operative complications and conversion rates when compared with delayed techniques.

Background A source of frustration during laparoscopic cholecystectomy involves extraction of the gallbladder through port sites smaller than the gallbladder itself. We describe the development and testing of a novel device for the safe, minimal enlargement of laparoscopic port sites to extract large, stone-filled gallbladders from the abdomen. Methods The study device consists of a handle with a retraction tongue to shield the specimen and a guide for a scalpel to incise the fascia within the incision. Patients enrolled underwent laparoscopic cholecystectomy. Gallbladder extraction was attempted. If standard measures failed, the device was implemented. Extraction time and device utility scores were recorded for each patient. Patients returned 3 - 4 weeks post-operatively for assessment of pain level, cosmetic effect, and presence of infectious complications. Results Twenty (51%) of 39 patients required the device. Average extraction time for the first 8 patients was 120 seconds. After interim analysis, an improved device was used in twelve patients, and average extraction time was 24 seconds. There were no adverse events. Post-operative pain ratings and incision cosmesis were comparable between patients with and without use of the device. Conclusion The study device enables safe and rapid extraction of impacted gallbladders through the abdominal wall. PMID:23897085

To compare the results and outcomes of the laparoscopic cholecystectomy (LC) with the small incision cholecystectomy (SIC). Observational study. Baqiyatallah Hospital, Tehran, Iran, from February 2008 to March 2009. Patients with symptomatic gallstones that were referred and enrolled in the study for LC or SIC. Operation, anaesthesia, analgesics and postoperative care were standardized. The patients were assessed for operation time, postoperative pain, nausea, vomiting, hospital stay, return to work time and complications in the postoperative period on day 1, 1 week, 1 month and 6 months, postoperatively. Of 144 patients, 81 underwent LC and 63 underwent SIC. Both groups were matched for age, gender, BMI, clinical findings and ASA grading. The mean duration of operation was 74 and 62 minutes in the LC and SIC groups, respectively (p = 0.0059). Duration of hospital stay and return to regular activities were shorter after LC compared to SIC. Pain scores, nausea and vomiting were the same in both groups, although the frequency of intra-operative complications were greater in LC compared to SIC. Outcome and complications of SIC were comparable with those of LC.

The aim of this study was to describe three cases of major vascular injuries after laparoscopic cholecystectomy depicted on magnetic resonance (MR) examination. Three female patients (mean age, 32 years; range, 22-39 years) were studied with clinical suspicion of bilio-vascular injuries after laparoscopic cholecystectomy. All MR examinations were performed within 24 h after the laparoscopic procedure. MR imaging was evaluated for major vascular injuries involving the arterial and portal venous system, for bile duct discontinuity, presence or absence of biliary dilation, stricture, excision injury, free fluid and collections. In the first patient, a type-IV Bismuth injury with associated intrahepatic bile ducts dilation was observed. Contrast-enhanced MR revealed lack of enhancement in the right hepatic lobe due to occlusion of the right hepatic artery and the right portal branch. This patient underwent right hepatectomy with hepatico-jejunostomy. In the other two cases, no visualization of the right hepatic artery and the right portal branch was observed on MR angiography. In the first case, the patient underwent right hepatectomy; in the second case, because of stable liver condition, the patient was managed conservatively. MR imaging combined with MR angiography and MR cholangiography can be performed emergently in patients with suspicion of bilio-vascular injury after laparoscopic cholecystectomy allowing the simultaneous evaluation of the biliary tree and the hepatic vascular supply that is essential for adequate treatment planning.

An unsolved problem of laparoscopic cholecystectomy is the optimal method of removing the gallbladder with thick walls and a large stone burden. Proposed solutions include fascial dilatation, stone crushing, and ultrasonic, high-speed rotary, or laser lithotripsy. Our observation was that extension of the fascial incision to remove the impacted gallbladder was time efficient and did not increase postoperative pain. We reviewed the narcotic requirements of 107 consecutive patients undergoing laparoscopic cholecystectomy. Fifty-two patients required extension of the umbilical incision, and 55 patients did not have their fascial incision enlarged. Parenteral meperidine use was 39.5 +/- 63.6 mg in the patients requiring fascial incision extension and 66.3 +/- 79.2 mg in those not requiring fascial incision extension (mean +/- standard deviation). Oral narcotic requirements were 1.1 +/- 1.5 doses vs 1.3 +/- 1.7 doses in patients with and without incision extension, respectively. The wide range of narcotic use in both groups makes these apparent differences not statistically significant. We conclude that protracted attempts at stone crushing or expensive stone fragmentation devices are unnecessary for the extraction of a difficult gallbladder during laparoscopic cholecystectomy.

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

Background Over the last decade, laparoscopic cholecystectomy has gained worldwide acceptance and considered to be as "gold standard" in the surgical management of symptomatic cholecystolithiasis. However, the incidence of bile duct injury in laparoscopic cholecystectomy is still two times greater compared to classic open surgery. The development of bile duct injury may result in biliary cirrhosis and increase in mortality rates. The mostly blamed causitive factor is the misidentification of the anatomy, especially by a surgeon who is at the beginning of his learning curve. Biliary tree injuries may be decreased by direct coloration of the cystic duct, ductus choledochus and even the gall bladder. Methods gall bladder fundus was punctured by Veress needle and all the bile was aspirated. The same amount of fifty percent methylene blue diluted by saline solution was injected into the gall bladder for coloration of biliary tree. The dissection of Calot triangle was much more safely performed after obtention of coloration of the gall bladder, cystic duct and choledocus. Results Between October 2003 and December 2004, overall 46 patients (of which 9 males) with a mean age of 47 (between 24 and 74) underwent laparoscopic cholecystectomy with methylene blue injection technique. The diagnosis of chronic cholecystitis (the thickness of the gall bladder wall was normal) confirmed by pre-operative abdominal ultrasonography in all patients. The diameters of the stones were greater than 1 centimeter in 32 patients and calcula of various sizes being smaller than 1 cm. were documented in 13 cases. One patient was operated for gall bladder polyp (our first case). Successful coloration of the gall bladder, cystic duct and ductus choledochus was possible in 43 patients, whereas only the gall bladder and proximal cystic duct were visualised in 3 cases. In these cases, ductus choledochus visibility was not possible. None of the patients developed bile duct injury. Conclusion The

Laparoscopic cholecystectomy (LC) is the operation of choice for removal of the gallbladder. Unrecognized bile duct injuries present with biliary peritonitis and systemic sepsis. Bile has been shown to cause damage to the vascular wall and therefore delay the healing of injured arteries leading to pseudoaneurysm formation. Failure to deal with bile leak and secondary infection may result in pseudoaneurysm formation. This study was to report the incidence and outcomes of pseudoaneurysm in patients with bile leak following LC referred to our hospital. A retrospective analysis of our prospectively maintained liver database using key words pseudoaneurysm, bile leak and bile duct injury following laparoscopic cholecystectomy from January 2000 to December 2005 was performed. A total of 86 cases were referred with bile duct injury and bile leak following LC and of these, 4 patients (4.5%) developed hepatic artery pseudoaneurysm (HAP) presenting with haemobilia in 3 and massive intra-abdominal bleed in 1. Selective visceral angiography confirmed pseudoaneurysm of the right hepatic artery in 2 cases, cystic artery stump in one and an intact but ectatic hepatic artery with surgical clips closely applied to the right hepatic artery at the origin of the cystic artery in the fourth case. Effective hemostasis was achieved in 3 patients with coil embolization and the fourth patient required emergency laparotomy for severe bleeding and hemodynamic instability due to a ruptured right hepatic artery. Of the 3 patients treated with coil embolization, 2 developed late strictures of the common hepatic duct (CHD) requiring hepatico-jejunostomy and one developed a stricture of left hepatic duct. All the 4 patients are alive at a median follow up of 17 months (range 1 to 65) with normal liver function tests. HAP is a rare and potentially life-threatening complication of LC. Biloma and subsequent infection are reported to be associated with pseudoaneurysm formation. Late duct stricture is

This present study sought to review the feasibility and patients' satisfaction of laparoscopic cholecystectomy to be perform as daycare procedure. Sixty-two patients with symptomatic gallstones were recruited within a year. They were randomized into overnight stay and daycare groups. The outcomes and post-operative complications were analyzed. Fifty-eight patients were eligible for analysis and four patients were excluded because of conversion to open cholecystectomy. All patients in daycare group reported no fever but two patients in the overnight stay group complaint of post-operative fever (p=0.150). The mean pain score using Visual Analogue Score (VAS) in daycare group was 2.93 but in the overnight stay was recorded as 3.59 (p=0.98). Five patients had post-operative nausea and vomiting (PONV) in daycare group compared to 2 patients in the overnight stay group (p=0.227). Patient's satisfaction were higher in the daycare group (p=0.160). All patients in daycare group were back at work within a week but in overnight stay, 11 patients had to stay off work for more than one week (p=0.01). Daycare laparoscopic cholecystectomy is safe and feasible. The satisfaction of daycare surgery is higher than overnight stay group. Patients' selection is an important aspect of its success.

Single-incision laparoscopic cholecystectomy (SILC) should not cost more or less than traditional laparoscopic cholecystectomy (LC). Retrospective cost data were collected from the accounting records of a single institution. A direct comparison of LC and SILC was conducted. Data on the SILC cases converted to LC were included. The total operating room (OR) cost (actual cost to the hospital for equipment, time, and personnel) and the total OR charges (total derived from the OR cost plus a margin to cover overhead costs beyond material costs) were examined. The total hospital charges (OR charges plus hospital charges accrued in the perioperative period) also were included. Descriptive statistics were used to analyze the data, with p values less than 0.05 considered statistically significant. Over a period of 19 months, 116 cases of minimally invasive cholecystectomy were evaluated. Of the 116 patients, 48 underwent LC during the first half of that period, and 68 patients underwent SILC during the second half of that period. Nine of the single-incision procedures were converted to traditional LC, for a 13% conversion rate. The groups were well matched from a demographics standpoint, with no significant differences in age, gender, body mass index (BMI), diagnoses, American Society of Anesthesiology (ASA) class, or payment. Comparison of all attempted SILCs, including those converted, with all LCs showed no significant difference in cost category totals. A significant difference among all cost variables was found when SILCs were compared with SILCs that required conversion to LC. A significant difference among the cost variables also was found when LCs were compared with converted SILCs. The cost for SILC did not differ significantly from that for LC when standard materials were used and the duration of the procedure was considered. Converted cases were significantly more expensive than completed SILC and LC cases.

An expert recommendation conference was conducted to identify factors associated with adverse events during laparoscopic cholecystectomy (LC) with the goal of deriving expert recommendations for the reduction of biliary and vascular injury. Nineteen hepato-pancreato-biliary (HPB) surgeons from high-volume surgery centers in six countries comprised the Research Institute Against Cancer of the Digestive System (IRCAD) Recommendations Group. Systematic search of PubMed, Cochrane, and Embase was conducted. Using nominal group technique, structured group meetings were held to identify key items for safer LC. Consensus was achieved when 80% of respondents ranked an item as 1 or 2 (Likert scale 1-4). Seventy-one IRCAD HPB course participants assessed the expert recommendations which were compared to responses of 37 general surgery course participants. The IRCAD recommendations were structured in seven statements. The key topics included exposure of the operative field, appropriate use of energy device and establishment of the critical view of safety (CVS), systematic preoperative imaging, cholangiogram and alternative techniques, role of partial and dome-down (fundus-first) cholecystectomy. Highest consensus was achieved on the importance of the CVS as well as dome-down technique and partial cholecystectomy as alternative techniques. The put forward IRCAD recommendations may help to promote safe surgical practice of LC and initiate specific training to avoid adverse events. © 2017 Japanese Society of Hepato-Biliary-Pancreatic Surgery.

As conventional laparoscopic procedural training requires live animals or cadaver organs, virtual simulation seems an attractive alternative. Therefore, we compared the transfer of training for the laparoscopic cholecystectomy from porcine cadaver organs vs virtual simulation to surgery in a live animal model in a prospective randomized trial. After completing an intensive training in basic laparoscopic skills, 3 groups of 10 participants proceeded with no additional training (control group), 5 hours of cholecystectomy training on cadaver organs (= organ training) or proficiency-based cholecystectomy training on the LapMentor (= virtual-reality training). Participants were evaluated on time and quality during a laparoscopic cholecystectomy on a live anaesthetized pig at baseline, 1 week (= post) and 4 months (= retention) after training. All research was performed in the Center for Surgical Technologies, Leuven, Belgium. In total, 30 volunteering medical students without prior experience in laparoscopy or minimally invasive surgery from the University of Leuven (Belgium). The organ training group performed the procedure significantly faster than the virtual trainer and borderline significantly faster than control group at posttesting. Only 1 of 3 expert raters suggested significantly better quality of performance of the organ training group compared with both the other groups at posttesting (p < 0.01). There were no significant differences between groups at retention testing. The virtual trainer group did not outperform the control group at any time. For trainees who are proficient in basic laparoscopic skills, the long-term advantage of additional procedural training, especially on a virtual but also on the conventional organ training model, remains to be proven.

A prospective, randomised trial of prophylactic antibiotics versus bag extraction in the prophylaxis of wound infection in laparoscopic cholecystectomy.

PubMed

Harling, R; Moorjani, N; Perry, C; MacGowan, A P; Thompson, M H

2000-11-01

Septic complications are rare following laparoscopic cholecystectomy if prophylactic antibiotics are given, as demonstrated in previous studies. Antibiotic treatment may be unnecessary and, therefore, undesirable, so we compared two forms of prophylaxis: a cephalosporin antibiotic and bag extraction of the dissected gallbladder. A total of 76 patients undergoing laparoscopic cholecystectomy were randomised to either receive an antibiotic or to have their gallbladder removed from the abdomen in a plastic bag. Complicated cases were excluded. There was a total of 6 wound infections (7.9%), 3 in each of the study groups. All these were associated with skin commensals. There were no other septic complications. Bacteriological studies grouped the organisms isolated from the bile and the wound as potential pathogens and likely commensals. A total of 10 potential pathogens were isolated, 9 of which were found in the group receiving antibiotics. We conclude that septic sequelae of uncomplicated laparoscopic cholecystectomy are uncommon, but clearly not entirely prevented by antibiotic or mechanical prophylaxis. Prophylactic antibiotics may not be required in uncomplicated laparoscopic cholecystectomy. Further study is warranted.

Biliary lithiasis is not much frequent in paediatric patients. The manegement of cholelithiasis in patients undergoing laparoscopic cholecystectomy is still controversial. We propose the preoperatory echographic study of the biliary tree 24-48 h before surgery, as the first choice, instead of the intraoperatory cholangiography. We made a retrospective study of 42 patients undergoing laparoscopic cholecystectomy due to symptomatic biliary lithiasis during the last 15 years, with ages between 18 months and 17-years-old (mean age 9,6-years-old) and weight between 11 and 70 kg (mean weight 42 kg) at the moment of surgery. Six of them had haematological illnesses, 17 came to the hospital because of acute abdominal pain, 10 had been studied because of recurrent abdominal pain and 9 had casual diagnoses. Abdominal sonography was performed in all patients 24-48 hours before surgery. Four children were diagnosed of biliary duct lithiasis: two choledocolithiasis and two stones in the cystic duct. One of the cystic stones was extracted in the operating room and the rest resolved spontaneously. One patient presented dilatation of choledocal duct after surgery, without any stones' evidence. Also this patient resolved spontaneously. We had no complications. Biliary lithiasis is not frequent in children, even if it seems to be increasing. A few of these patients will suffer of choledocolithiasis. The intraoperatory exploration of the biliary tree during laparoscopic surgery is technically difficult due the small size of paediatric patients. Cholangiography is not always successful and can produce some important complications as pancreatitis. Preoperative sonography 24-48 hours before surgery is a safe and efficient method for the diagnosis and follow-up of paediatric patients with biliary lithiasis undergoing laparoscopic cholecystectomy. It is safe enough to be performed without intraoperatory cholangiography.

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

Situs inversus totalis is a rare condition where the organs in the body is placed in the opposite side. When such patient presents with the diseases of the intra abdominal organs the diagnosis is challenging and the operative procedure to be performed will be difficult. This may require the anticipation of variations in anatomy, ergonomic changes required during surgery and mastery over the operative skills in reversed anatomy. Cholelithiasis in situs inversus totalis is one such situation. Herein we report a case of situs inversus totalis who underwent successful laparoscopic cholecystectomy for symptomatic gallbladder calculi. PMID:25177601

During laparoscopic cholecystectomy, perforation of the gallbladder can occurs in < or = 20% of cases, while gallstone spillage occurs in < or = 6% of cases. In most cases, there are no consequences. Gallstones can be lost in the abdominal wall as well as the abdomen during extraction of the gallbladder. The fate of such lost gallstones, which can lead to the formation of an abscess, an abdominal wall mass, or a persistent sinus, has not been studied adequately. Herein we report the case of a persistent sinus of the abdominal wall after an emergent laparoscopic cholecystectomy in an 82-year-old woman with gangrenous cholecystitis and perforation of the friable wall in association with an empyema of the gallbladder. The culture of the obtained pus was positive for Escherichia coli. After a small leak of dirty fluid from the wound of the epigastric port site of 4 months' duration, surgical exploration under local anesthesia revealed that the sinus was caused by spilled gallstones impacting into the abdominal wall between the posterior sheath and left rectus abdominalis muscle. The removal of the stones resulted in complete healing. Long-term complications after laparoscopic cholecystectomy involving the abdominal wall are rare but important possible consequences that could be avoided.

Robotic-assisted surgery is gaining popularity in general surgery. Our objective was to evaluate and compare operative outcomes and total costs for robotic cholecystectomy (RC) and laparoscopic cholecystectomy (LC). A retrospective review was performed for all patients who underwent single-procedure RC and LC from January 2011 to July 2015 by a single surgeon at a large academic medical center. Demographics, diagnosis, perioperative variables, postoperative complications, 30-day readmissions, and operative and hospital costs were collected and analyzed between those patient groups. A total of 237 patients underwent RC or LC, and comprised the study population. Ninety-seven patients (40.9 %) underwent LC, and 140 patients (50.1 %) underwent RC. Patients who underwent RC had a higher body mass index (p = 0.03), lower rates of coronary artery disease (p < 0.01), and higher rates of chronic cholecystitis (p < 0.01). There were lower rates of intraoperative cholangiography (p < 0.01) and conversion to an open procedure (p < 0.01), however longer operative times (p < 0.01) for patients in the RC group. There were no bile duct injuries in either group, no difference in bile leak rates (p = 0.65), or need for reoperation (p = 1.000). Cost analysis of outpatient-only procedures, excluding cases with conversion to open or use of intraoperative cholangiography, demonstrated higher total charges (p < 0.01) and cost (p < 0.01) and lower revenue (p < 0.01) for RC compared to LC, with no difference in total payments (p = 0.34). Robotic cholecystectomy appears to be safe although costlier in comparison with laparoscopic cholecystectomy. Further studies are needed to understand the long-term implications of robotic technology, the cost to the health care system, and its role in minimally invasive surgery.

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.

Background: Laparoscopic cholecystectomy (LC) is the gold standard for gallstone disease. Many studies have confirmed the safety and feasibility of LC and have shown that it is comparable regarding complications to open cholecystectomy (OC). The aim of this study was to evaluate the outcomes of LC including safety, feasibility in a resource-poor setting like Yemen, and also to compare the outcomes of LC with those of OC. Methods: This was a prospective, nonrandomized, comparative study of 112 patients who were admitted to Alburaihy Hospital with a diagnosis of gallstone disease and underwent cholecystectomy from July 1998 to March 2004. Hospital stay, duration of operation, postoperative analgesia, and morbidity due to wound infection, bile leak, common bile duct (CBD) injury, missed CBD stone, bleeding, subphrenic abscess, and hernia were evaluated. Patients were followed up on an outpatient basis. Results: Forty-nine patients underwent LC and 63 patients underwent OC. The mean age of LC patients was 43.96 years and of OC patients was 44.63 years. The 2 groups were similar in terms of age (p=0.740) and sex (p=0.535). No significant difference was found in the incidence of acute cholecystitis between the 2 groups (p=0.000). The mean operative duration for LC was 39.88 minutes versus 56.76 minutes for OC (p=0.000), and the mean hospital stay was 1.63 and 5.38 days for LC and OC, respectively (p=0.000). A drain was used frequently in OC (p=0.000). LC patients needed less analgesia (p=0.000). The morbidity rate in LC was 12.2% versus 6.3% for OC, which was not statistically significant (p=0.394), (p>0.05). Wound infection and bile leak were more common with LC. No mortalities were reported in either group. Conclusion: An experienced surgeon can perform LC safely and successfully in a resource-limited setting. As in other studies, LC outcomes were better than OC outcomes. PMID:18402743

Haptics is an expensive addition to virtual reality (VR) simulators, and the added value to training has not been proven. This study evaluated the benefit of haptics in VR laparoscopic surgery training for novices. The Simbionix LapMentor II haptic VR simulator was used in the study. Randomly, 33 laparoscopic novice students were placed in one of three groups: control, haptics-trained, or nonhaptics-trained group. The control group performed nine basic laparoscopy tasks and four cholecystectomy procedural tasks one time with haptics engaged at the default setting. The haptics group was trained to proficiency in the basic tasks and then performed each of the procedural tasks one time with haptics engaged. The nonhaptics group used the same training protocol except that haptics was disengaged. The proficiency values used were previously published expert values. Each group was assessed in the performance of 10 laparoscopic cholecystectomies (alternating with and without haptics). Performance was measured via automatically collected simulator data. The three groups exhibited no differences in terms of sex, education level, hand dominance, video game experience, surgical experience, and nonsurgical simulator experience. The number of attempts required to reach proficiency did not differ between the haptics- and nonhaptics-training groups. The haptics and nonhaptics groups exhibited no difference in performance. Both training groups outperformed the control group in number of movements as well as path length of the left instrument. In addition, the nonhaptics group outperformed the control group in total time. Haptics does not improve the efficiency or effectiveness of LapMentor II VR laparoscopic surgery training. The limited benefit and the significant cost of haptics suggest that haptics should not be included routinely in VR laparoscopic surgery training.

Background: Supraglottic airway devices (SADs), such as ProSealTM laryngeal mask airway (PLMA), which produce high oropharyngeal seal pressure (OSP) and have the facility for gastric decompression have been used in laparoscopic procedures. i-gel is a new SAD which shares these features with the PLMA. This study was designed to compare the respiratory mechanics of these two devices during positive pressure ventilation in anaesthetised adult patients undergoing laparoscopic cholecystectomy. Patients & Methods: The study included 60 ASA I-II adult patients scheduled for laparoscopic cholecystectomy. The patients were randomized to two groups of 30 each, with either PLMA or i-gel as their airway device. Anaesthesia and premedication were standardized for both the groups. In addition to routine monitoring, neuromuscular monitoring with TOF ratio, OSP and respiratory mechanics monitoring (dynamic compliance, resistance, work of breathing, measured minute ventilation and peak airway pressures) were employed. Fibreoptic evaluation of positioning of the devices and adverse events related to them were also compared. Results: The OSP (cm H2O) were higher for PLMA (38.9 vs. 35.6, P=0.007). The respiratory mechanics parameters using the two devices were comparable apart from the dynamic compliance, which was significantly higher with i-gel (P < 0.05). Malrotation was higher with i-gel than with PLMA (15 vs. 5, P = 0.006). Conclusion: The PLMA formed a better seal while the dynamic compliance was higher with the i-gel. Both devices provided optimal ventilation and oxygenation and the adverse events were also comparable. PMID:21547168

Is mini-laparoscopic cholecystectomy any better than the gold standard?: A comparative study

BACKGROUND: 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. MATERIALS AND METHODS: 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. RESULTS: 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). CONCLUSION: 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. PMID:27251827

Simulators are widely used in occupations where practice in authentic environments would involve high human or economic risks. Surgical procedures can be simulated by increasingly complex and expensive techniques. This review gives an update on computer-based virtual reality (VR) simulators in training for laparoscopic cholecystectomies. From leading databases (Medline, Cochrane, Embase), randomised or controlled trials and the latest systematic reviews were systematically searched and reviewed. Twelve randomised trials involving simulators were identified and analysed, as well as four controlled studies. Furthermore, seven studies comparing black boxes and simulators were included. The results indicated any kind of simulator training (black box, VR) to be beneficial at novice level. After VR training, novice surgeons seemed to be able to perform their first live cholecystectomies with fewer errors, and in one trial the positive effect remained during the first ten cholecystectomies. No clinical follow-up data were found. Optimal learning requires skills training to be conducted as part of a systematic training program. No data on the cost-benefit of simulators were found, the price of a VR simulator begins at EUR 60 000. Theoretical background to learning and limited research data support the use of simulators in the early phases of surgical training. The cost of buying and using simulators is justified if the risk of injuries and complications to patients can be reduced. Developing surgical skills requires repeated training. In order to achieve optimal learning a validated training program is needed.

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.

Laparoscopic cholecystectomy under spinal anesthesia: comparative study between conventional-dose and low-dose hyperbaric bupivacaine

2011-01-01

Background Laparoscopic cholecystectomy has the advantages of causing less postoperative pain and requiring a short hospital stay, and therefore is the treatment of choice for cholelithiasis. This study was designed to compare spinal anesthesia using hyperbaric bupivacaine given as a conventional dose by lumbar puncture or as a low-dose by thoracic puncture. Methods A total of 140 patients with symptomatic gallstone disease were randomized to undergo laparoscopic cholecystectomy with low-pressure CO2 pneumoperitoneum under spinal anesthesia using either conventional lumbar spinal anesthesia (hyperbaric bupivacaine 15 mg and fentanyl 20 mg) or low-dose thoracic spinal anesthesia (hyperbaric bupivacaine 7.5 mg and fentanyl 20 μg). Intraoperative parameters, postoperative pain, complications, recovery time, and patient satisfaction at follow-up were compared between the two treatment groups. Results All procedures were completed under spinal anesthesia, with no cases needing conversion to general anesthesia. Values for time for block to reach the T3 dermatomal level, duration of motor and sensory block, and hypotensive events were significantly lower with low-dose bupivacaine. Postoperative pain was higher for low-dose hyperbaric bupivacaine at 6 and 12 hours. All patients were discharged after 24 hours. Follow-up 1 week postoperatively showed all patients to be satisfied and to be keen advocates of spinal anesthesia. Conclusion Laparoscopic cholecystectomy can be performed successfully under spinal anesthesia. A small dose of hyperbaric bupivacaine 7.5 mg and 20 μg fentanyl provides adequate spinal anesthesia for laparoscopy and, in comparison with hyperbaric bupivacaine 15% and fentanyl 20 μg, causes markedly less hypotension. The low-dose strategy may have an advantage in ambulatory patients because of the earlier recovery of motor and sensory function and earlier discharge. PMID:22915892

While laparoscopic cholecystectomy is generally considered to be less painful than open surgery, pain is one of the important reasons for delayed discharge after day surgery resulting in overnight stay following laparoscopic cholecystectomy. The safety and effectiveness of local anaesthetic wound infiltration in people undergoing laparoscopic cholecystectomy is not known. To assess the benefits and harms of local anaesthetic wound infiltration in patients undergoing laparoscopic cholecystectomy and to identify the best method of local anaesthetic wound infiltration with regards to the type of local anaesthetic, dosage, and time of administration of the local anaesthetic. We searched the Cochrane Central Register of Controlled Trials (CENTRAL), MEDLINE, EMBASE, and Science Citation Index Expanded until February 2013 to identify studies of relevance to this review. We included randomised clinical trials for benefit and quasi-randomised and comparative non-randomised studies for treatment-related harms. Only randomised clinical trials (irrespective of language, blinding, or publication status) comparing local anaesthetic wound infiltration versus placebo, no intervention, or inactive control during laparoscopic cholecystectomy, trials comparing different local anaesthetic agents for local anaesthetic wound infiltration, and trials comparing the different times of local anaesthetic wound infiltration were considered for the review. Two review authors collected the data independently. We analysed the data with both fixed-effect and random-effects meta-analysis models using RevMan. For each outcome, we calculated the risk ratio (RR) or mean difference (MD) with 95% confidence interval (CI). Twenty-six trials fulfilled the inclusion criteria of the review. All the 26 trials except one trial of 30 participants were at high risk of bias. Nineteen of the trials with 1263 randomised participants provided data for this review. Ten of the 19 trials compared local anaesthetic

Laparoscopic cholecystectomy (VALC) represents the treatment of choice for the symptomatic gallstones. However the occurrence of an adenocarcinoma of the gallbladder results a controindication for this surgical technique. We present a case of a 52 years old woman who underwent a VALC; histology revealed a gallbladder adenocarcinoma. For this reason the patient underwent a second operation that is right hepatic trisegmentectomy. Six months later the patient presented with a parietal recurrence at the extraction site of the gallbladder. We discuss the possible mechanism responsible for carcinomatous dissemination during laparoscopic surgery and we raccommend the use of some procedures in order to limit the risk and eventually to treat a neoplastic parietal seeding. These complications suggest the problem about the utility and the future played by video assisted laparoscopic surgery in the diagnosis and treatment of intraabdominal malignancies.

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

Introduction Many researchers have addressed overdosage and inappropriate use of antibiotics. Many meta-analyses have investigated antibiotic prophylaxis for low-risk laparoscopic cholecystectomy with the aim of reducing unnecessary antibiotic use. Most of these meta-analyses have concluded that prophylactic antibiotics are not required for low-risk laparoscopic cholecystectomies. This study aimed to assess the validity of this conclusion by systematically reviewing these meta-analyses. Methods A systematic review was undertaken. Searches were limited to meta-analyses and systematic reviews. PubMed and Cochrane Library electronic databases were searched from inception until March 2016 using the following keyword combinations: ‘antibiotic prophylaxis’, ‘laparoscopic cholecystectomy’ and ‘systematic review or meta-analysis’. Two independent reviewers selected meta-analyses or systematic reviews evaluating prophylactic antibiotics for laparoscopic cholecystectomy. All of the randomised controlled trials (RCTs) analysed in these meta-analyses were also reviewed. Results Seven meta-analyses regarding prophylactic antibiotics for low-risk laparoscopic cholecystectomy that had examined a total of 28 RCTs were included. Review of these meta-analyses revealed 48 miscounts of the number of outcomes. Six RCTs were inappropriate for the meta-analyses; one targeted patients with acute cholecystitis, another measured inappropriate outcomes, the original source of a third was not found and the study protocols of the remaining three were not appropriate for the meta-analyses. After correcting the above miscounts and excluding the six inappropriate RCTs, pooled risk ratios (RRs) were recalculated. These showed that, contrary to what had previously been concluded, antibiotics significantly reduced the risk of postoperative infections. The rates of surgical site, distant and overall infections were all significantly reduced by antibiotic administration (RR (95% CI); 0

1999-01-01

The Expert Commission for medical malpractice which is part of the Medical Chamber of Nordrhein received about 60 applications in connection with laparoscopic cholecystectomy; as of August 1998 5 complaints were let off and 11 of them are still being considered. So far 44 complaints have been considered and in 25 of them medical malpractice has been established. The medical malpractice detected laparoscopic cholecystectomy cases were mainly bile duct injuries of which 13 required a biliodigestive anastomosis for reconstruction, four cases required and end-to-end anastomosis and in one case a T-tube drainage was needed. The youngest one of these patients was 21 years old, the oldest one was 61 years old. Four times the bile duct injury was not considered as malpractice, because it could be intraoperatively made out and immediately treated. Trocar injuries were twice a cause for malpractice and once it was not. Each of the following cases was also recognized as a malpractice. One lost gallstone one dislocated Roedersnare, one electric injury, one delayed reintervention and one insufficient information. The following cases were decided as non-malpractice: in two cases a slipped clip, in five cases subhepatical hematoma/abscess, in three cases a secondary bleeding, once a lesion of the splenic capsule and finally a running sore with subsequent incisional hernia. Three courses of treatment with consequence of death also contained mistakes: one electric injury of the bowel, one bile duct lesion and one information rebuke. The bile duct injury is the most considerable risk for laparoscopic cholecystectomy and implies also a high risk for the future health. The experienced surgeon distinguishes himself by the fact that he is right about the situation and converts sooner that later to conventional cholecystectomy if there's any doubt. In open surgery the principle is applied that structures may be only divided when they are clearly identified. The same goes even on a wider

Laparoscopic cholecystectomy in double gallbladder with dual pathology.

2014-04-01

Double gallbladder is a rare embryological anomaly of clinical significance. Despite availability of modern imaging, only 50% of recently reported cases had preoperative diagnosis, which is desirable in every case to avoid serious operative complications. Double pathology in double gallbladder is extremely rare with only 3 reporting's available till date to the best of author's knowledge. With a preoperative diagnosis of double gallbladder, laparoscopic cholecystectomy can be safely and successfully performed with meticulous dissection, aided by operative cholangiogram. However in all such attempts a lower threshold should be kept for conversion to open surgery. Awareness about this anomaly amongst radiologists and surgeons is of crucial importance. Double gallbladder does not present with any specific symptom, neither it increases disease possibility in either lobe. Prophylactic cholecystectomy has no role in asymptomatic cases diagnosed accidentally. Author reports a case of a symptomatic young male with double gallbladder who presented with short history of dyspepsia, abdominal pain and fever. Definite preoperative diagnosis was reached with ultrasound scan and magnetic resonance cholangio pancreatography and subsequently dealt with laparoscopically. Calculous cholecystitis affected one lobe and acalculous empyema the other. While the 1st lobe drained though a cystic duct into common bile duct (CBD), the 2nd was without any communication with either CBD or its counterpart, thus remained as a blind vesicle.

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.

2016-03-01

Although simulation-based training allows residents to become proficient in surgical skills outside the OR, residents still depend on senior surgeons' guidance in transferring skills accumulated from simulators into the operating room. This study aimed to identify and classify explicit instructions made by attending surgeons to their residents during laparoscopic surgery. Through these instructions, we examined the role gaze guidance plays in OR-based training. A total of ten laparoscopic cholecystectomy cases being performed by PGY4 residents were analyzed. The explicit directional instructions given by the mentoring attending surgeons to their residents were identified and classified into four categories based on their locations in the coordinate system. These categories were further combined into two classes, based on the target of instructions. The frequencies of instructions in the two classes were compared, and effect size was calculated. There were 1984 instructions identified in the ten cases. The instructions were categorized into instrument guidance (38.51%) and gaze guidance (61.49%). The instrument guidance focused on moving the instruments to perform surgical tasks, including directions to targets, instrument manipulation, and instrument interaction. The gaze guidance focused on achieving common ground during the operation, including target identification and target fixation. The frequency of gaze guidance is significantly higher than instrument guidance in a laparoscopic cholecystectomy (p < 0.001) with a large effect size (r = 0.6). Gaze guidance has become the main focus of OR-based training. The results show a tight connection between adopting expert gaze and performing surgical tasks and suggest that gaze training should be integrated into the simulation training.

Although single-incision laparoscopic cholecystectomy (SILC) has no advantage over conventional laparoscopic cholecystectomy (LC), except for better cosmesis, few reports have discussed the criteria for SILC. The aim of this study was to evaluate the suitability of our criteria for SILC. During the study period, SILC was performed at our institution under the following criteria. The inclusion criteria were elective surgery, age of < 60 years, and body mass index of < 30 kg/m 2 . The exclusion criteria were a thick gallbladder wall, history of choledocholithiasis, previous abdominal surgery, and serious concomitant disease. We reviewed data regarding consecutive patients who underwent LC at our institution from November 2009 to March 2016. The data were assessed with respect to patient characteristics, operative data, and postoperative outcomes. A total of 1093 patients underwent elective LC, and 232 (21.2%) of these patients underwent SILC using our criteria. Fourteen patients (6.0%) who underwent SILC required extra ports. Among the patients aged < 60 years, 50.2% (232/462) underwent SILC. There were few adverse events, including intra- and postoperative complications, among the patients who underwent SILC. The above-mentioned criteria are safe, necessary, and sufficient for SILC over conventional LC. Copyright © 2016. Published by Elsevier Taiwan.

The treatment of children with biliary dyskinesia (BD) is controversial. As we recently observed an increasing frequency of referrals for BD in our institution the aim of the study was to re-evaluate the long-term outcome in children with BD. Children with laparoscopic cholecystectomy (LC) for suspected BD between 8/2006 and 5/2011 were included. A pathologic ejection fraction (EF) was defined as <35%. The long-term effect of cholecystectomy was assessed via a Likert scale symptom questionnaire. 82 children (median age 13.5 years, mean BMI 25.8) were included. CCK-HIDA scan was pathologic in 74 children (90.2%). Mean EF was 16.4%. Histology revealed chronic cholecystitis in 48 (58.5%) children and was normal in 30 children (36.5%). The frequency of LC for suspected BD increased by a factor of 4.3 in the last 10 years. Long term follow-up showed that only 23/52 children (44.2%) were symptom-free after LC. Patients with chronic inflammation were more likely to have persistent symptoms (p=0.017). An EF<15% was associated with a resolution of symptoms (p=0.031). The frequency of LC for suspected BD in our institution has increased significantly during recent years. The long-term efficacy in our cohort was only 44.2%. We believe that laparoscopic cholecystectomy is likely helpful in patients with an EF<15%. However, in children with an EF of 15%-35%, based upon our data, we would highly recommend an appropriately thorough pre-op testing to exclude other gastrointestinal disorders prior to consideration of operative management.

2017-10-01

Intravenous injection of indocyanine green (ICG) is used to illuminate extrahepatic biliary anatomy. Fluorescence of biliary structures may lower surgical complications that can arise due to inadvertent injury to the common bile duct. We describe a method of injecting ICG directly into the gallbladder to define the cystic duct and common bile duct anatomy. A standard laparoscopic cholecystectomy was performed using a laparoscope with near-infrared imaging capability. Before dissection, the gallbladder was punctured with a cholangiogram catheter or a pigtail catheter to aspirate the bile within the gallbladder. The aspirated bile is mixed with ICG solution, which is reinjected into the gallbladder to fluoresce the gallbladder, cystic duct, and common bile duct structures. Eleven patients underwent direct gallbladder ICG injection for fluorescence cholangiography during cholecystectomy. Direct gallbladder ICG injection clearly defined the extrahepatic biliary anatomy, including the cystic duct-common bile duct junction, by fluorescence. In addition, the dissection plane between the gallbladder and the liver is highlighted with the gallbladder ICG fluorescence. Direct gallbladder ICG injection provides immediate visualization of extrahepatic biliary structures and clarifies the dissection plane between the gallbladder and the liver bed.

Post-laparoscopic pain syndrome is well recognized and characterized by abdominal and particularly shoulder tip pain; it occurs frequently following laparoscopic cholecystectomy. The etiology of post-laparoscopic pain can be classified into three aspects: visceral, incision, and shoulder. The origin of shoulder pain is only partly understood, but it is commonly assumed that the cause is overstretching of the diaphragmatic muscle fibers owing to a high rate of insufflations. This study aimed to compare the frequency and intensity of shoulder tip pain between low-pressure (7 mmHg) and standard-pressure (14 mmHg) in a prospective randomized clinical trial. One hundred and forty consecutive patients undergoing elective laparoscopic cholecystectomy were randomized prospectively to either high- or low-pressure pneumoperitoneum and blinded by research nurses who assessed the patients during the postoperative period. The statistical analysis included sex, mean age, weight, American Society of Anesthesiologists (ASA) grade, operative time, complication rate, duration of surgery, conversion rate, postoperative pain by using visual analogue scale, number of analgesic injections, incidence and severity of shoulder tip pain, and postoperative hospital stay. p < 0.05 was considered indicative of significance. The characteristics of the patients were similar in the two groups except for the predominance of males in the standard-pressure group (controls). The procedure was successful in 68 of 70 patients in the low-pressure group compared with in 70 patients in the standard group. Operative time, number of analgesic injections, visual analogue score, and length of postoperative days were similar in both groups. Incidence of shoulder tip pain was higher in the standard-pressure group, but not statistically significantly so (27.9% versus 44.3%) (p = 0.100). Low-pressure pneumoperitoneum tended to be better than standard-pressure pneumoperitoneum in terms of lower incidence of

Generally, before being operated on, patients will be given informal information by the healthcare providers involved in the care of the patients (doctors, nurses, ward clerks, or healthcare assistants). This information can also be provided formally in different formats including written information, formal lectures, or audio-visual recorded information. To compare the benefits and harms of formal preoperative patient education for patients undergoing laparoscopic cholecystectomy. We searched the Cochrane Central Register of Controlled Trials (CENTRAL) (Issue 2, 2013), MEDLINE, EMBASE, and Science Citation Index Expanded to March 2013. We included only randomised clinical trials irrespective of language and publication status. Two review authors independently extracted the data. We planned to calculate the risk ratio with 95% confidence intervals (CI) for dichotomous outcomes, and mean difference (MD) or standardised mean difference (SMD) with 95% CI for continuous outcomes based on intention-to-treat analyses when data were available. A total of 431 participants undergoing elective laparoscopic cholecystectomy were randomised to formal patient education (215 participants) versus standard care (216 participants) in four trials. The patient education included verbal education, multimedia DVD programme, computer-based multimedia programme, and Power Point presentation in the four trials. All the trials were of high risk of bias. One trial including 212 patients reported mortality. There was no mortality in either group in this trial. None of the trials reported surgery-related morbidity, quality of life, proportion of patients discharged as day-procedure laparoscopic cholecystectomy, the length of hospital stay, return to work, or the number of unplanned visits to the doctor. There were insufficient details to calculate the mean difference and 95% CI for the difference in pain scores at 9 to 24 hours (1 trial; 93 patients); and we did not identify clear evidence of

A descriptive analysis of day-case laparoscopic cholecystectomy (ALC) in a cohort of 1,600 consecutive patients performed in Instituto de Cirugía y Aparato Digestivo (ICAD), Clínica Quirón de Valencia in the period 1997-2010. Prospective observational study of 1,601 consecutive patients undergoing elective laparoscopic cholecystectomy (LC) provided by the regional health service and private health companies. 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.

Laparoscopic cholecystectomy entails an increased risk of gallbladder rupture and consequent loss of stones in the abdominal cavity. Herein we report the case of a 51-year-old male patient, who underwent laparoscopic cholecystectomy 2 years before presentation to our hospital. He had experienced tension sensation and epigastric pain since 4 months postoperatively. A well-defined epigastric mass, which was hard and painful on palpation, was detected and later confirmed by ultrasonography and CT scan. Explorative laparotomy revealed a mass in the area of the gastrocolic ligament,resulting from biliary gallstones in conjunction with a perimetral inflammatory reaction. A review of the literature showed that the incidence of gallbladder lesions during laparoscopy is 13-40%. In order to prevent this complication, meticulous isolation of the gallbladder, proper dissection of the cystic duct and artery, and careful extraction through the umbilical access are required. Ligation after the rupture or use of an endo-bag may be helpful. The loss of gallstones and their retention in the abdominal cavity should be noted in the description of the surgical procedure.

To determine pre-operative criteria to predict duration and technical difficulty of laparoscopic cholecystectomies that will aid in identifying patients suitable for training lists. A prospective analysis of 835 consecutive patients who underwent laparoscopic cholecystectomies. Data collected included patient demographics, endoscopic retrograde cholangiopancreatography (ERCP), endoscopic sphincterotomy (ES), duration of surgery (from skin incision to skin closure), peri-operative and postoperative complications and histological gallbladder wall thickness. Post-operative complications were seen in 3% (n=20). Overall open conversion rate was 2%. The mean duration of surgery was 78.76 +/- 1.75 minutes. Age, ERCP and ES were not independent predictors of a long operation time. However, a positive correlation was seen with histological gallbladder wall thickness and duration of surgery (p=0.001). The mean operating time for gallbladder wall thickness < 3 mm was 72.1 +/- 1.62 minutes whereas that for > 3 mm thickness was 83.3 +/- 2.05 minutes (p=<0.001). Gallbladder wall thickness can be used as an independent predictor of a long operation time.

A comparison of 1-port, 2-port, 3-port, and 4-port laparoscopic cholecystectomy techniques from the point of view of workflow criteria was made to both identify specific workflow components that can cause surgical disturbances and indicate good and bad practices. As a case study, laparoscopic cholecystectomies, including manual tasks and interactions within teamwork members, were video-recorded and analyzed on the basis of specially encoded workflow information. The parameters for comparison were defined as follows: surgery time, tool and hand activeness, operator's passive work, collisions, and operator interventions. It was found that 1-port cholecystectomy is the worst technique because of nonergonomic body position, technical complexity, organizational anomalies, and operational dynamism. The differences between laparoscopic techniques are closely linked to the costs of the medical procedures. Hence, knowledge about the surgical workflow can be used for both planning surgical procedures and balancing the expenses associated with surgery.

Background Ultrasonic dissection has been suggested as an alternative to monopolar electrocautery in laparoscopic cholecystectomy because it generates less tissue damage and may have a lower incidence of gallbladder perforation. We compared the 2 methods to determine the incidence of gallbladder perforation and its intraoperative consequences. Methods We conducted a prospective randomized controlled trial between July 2008 and December 2009 involving adult patients with symptomatic gall stone disease who were eligible for laparoscopic cholecystectomy. Patients were randomly assigned before administration of anesthesia to electrocautery or ultrasonic dissection. Both groups were compared for incidence of gallbladder perforation during dissection, bile leak, stones spillage, lens cleaning, duration of surgery and estimation of risk of gall-bladder in the presence of complicating factors. Results We included 60 adult patients in our study. The groups were comparable with respect to demographic characteristics, symptomatology, comorbidities, previous abdominal surgeries, preoperative ultrasonography findings and intraoperative complications. The overall incidence of gallbladder perforation was 28.3% (40.0% in the electrocautery v. 16.7% in the ultrasonic dissection group, p = 0.045). Bile leak occurred in 40.0% of patients in the electrocautery group and 16.7% of patients in ultrasonic group (p = 0.045). Lens cleaning time (p = 0.015) and duration of surgery (p = 0.001) were longer in the electrocautery than the ultrasonic dissection group. There was no statistical difference in stone spillage between the groups (p = 0.62). Conclusion Ultrasonic dissection is safe and effective, and it improves the operative course of laparoscopic cholecystectomy by reducing the incidence of gallbladder perforation. PMID:22854110

The aim of this study was to evaluate the intraoperative and postoperative complications of laparoscopic cholecystectomy, as well as the frequency of conversions. Medical records of 740 patients who had laparoscopic cholecystectomy were analysed retrospectively. We evaluated patients for the presence of potential risk factors that could predict the development of complications such as age, gender, body mass index, white blood cell count and C-reactive protein (CRP), gallbladder ultrasonographic findings, and pathohistological analysis of removed gallbladders. The correlation between these risk factors was also analysed. There were 97 (13.1%) intraoperative complications (IOC). Iatrogenic perforations of a gallbladder were the most common complication - 39 patients (5.27%). Among the postoperative complications (POC), the most common ones were bleeding from abdominal cavity 27 (3.64%), biliary duct leaks 14 (1.89%), and infection of the surgical wound 7 patients (0.94%). There were 29 conversions (3.91%). The presence of more than one complication was more common in males (OR = 2.95, CI 95%, 1.42-4.23, p < 0.001). An especially high incidence of complications was noted in patients with elevated white blood cell count (OR = 3.98, CI 95% 1.68-16.92, p < 0.01), and CRP (OR = 2.42, CI 95% 1.23-12.54, p < 0.01). The increased incidence of complications was noted in patients with ultrasonographic finding of gallbladder empyema and increased thickness of the gallbladder wall > 3 mm (OR = 4.63, CI 95% 1.56-17.33, p < 0.001), as well as in patients with acute cholecystitis that was confirmed by pathohistological analysis (OR = 1.75, CI 95% 2.39-16.46, p < 0.001). Adopting laparoscopic cholecystectomy as a new technique for treatment of cholelithiasis, introduced a new spectrum of complications. Major biliary and vascular complications are life threatening, while minor complications cause patient discomfort and prolongation of the hospital stay. It is important recognising

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.

With the advancement of laparoscopic instruments and computer sciences, complex surgical procedures are expected to be safely performed by robot assisted telemanipulative laparoscopic surgery. The da Vinci system (Intuitive Surgical, Mountain View, CA, USA) became available at the many surgical fields. The wrist like movements of the instrument's tip, as well as 3-dimensional vision, could be expected to facilitate more complex laparoscopic procedure. Here, we present the first Korean experience of da Vinci robotic assisted laparoscopic cholecystectomy and discuss the introduction and perspectives of this robotic system. PMID:17594166

The ultimate therapy for acute cholecystitis is cholecystectomy. However, in critically ill elderly patients the mortality of emergency cholecystectomy may reach up to 30%. Open cholecystostomy performed under local anesthesia was considered to be the procedure of choice for treatment of acute cholecystitis in high-risk patients. In recent years, ultrasound- or computed tomography (CT)-guided percutaneous transhepatic cholecystostomy (PTHC) replaced open cholecystostomy for the treatment of acute cholecystitis in critically ill patients. The aim of the present study was to evaluate the results of a 5-year protocol using PTHC followed by delayed laparoscopic cholecystectomy for the treatment of acute cholecystitis in critically ill patients. We reviewed the charts of 55 patients who underwent PTHC at the Hadassah University Hospital Mount Scopus during the years 1994 to 1999. The main indications for PTHC among this group of severely sick and high-risk patients was biliary sepsis and septic shock in 23 patients (42%); and severe comorbidities in 32 patients (58%). The median age was 74 (32 to 98) years, 33 were female and 22 male. Successful biliary drainage by PTHC was achieved in 54 of 55 (98%) of the patients. The majority of the patients (31 of 55) were drained transhepaticlly under CT guidance. The rest, (24 of 55) were drained using ultrasound guidance followed by cholecystography for verification. Complications included hepatic bleeding that required surgical intervention in 1 patient and dislodgment of the catheter in 9 patients that was reinserted in 2 patients. Three patients died of multisystem organ failure 12 to 50 days following the procedure. The remaining 52 patients recovered well with a mean hospital stay of 15.5 plus minus 11.4 days. Thirty-one patients were able to undergo delayed surgery: 28 underwent laparoscopic cholecystectomy of whom 4 (14%) were converted to open cholecystectomy. This was compared with a 1.9% conversion rate in 1

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.

AIM: To present and integrate findings of studies investigating the effects of laparoscopic cholecystectomy on various aspects of lung function. METHODS: We extensively reviewed literature of the past 24 years concerning the effects of laparoscopic cholecystectomy in comparison to the open procedure on many aspects of lung function including spirometric values, arterial blood gases, respiratory muscle performance and aspects of breathing control, by critically analyzing physiopathologic interpretations and clinically important conclusions. A total of thirty-four articles were used to extract information for the meta-analysis concerning the impact of the laparoscopic procedure on lung function and respiratory physiopathology. The quality of the literature reviewed was evaluated by the number of their citations and the total impact factor of the corresponding journals. A fixed and random effect meta-analysis was used to estimate the pooled standardized mean difference of studied parameters for laparoscopic (LC) and open (OC) procedures. A crude comparison of the two methods using all available information was performed testing the postoperative values expressed as percentages of the preoperative ones using the Mann-Whitney two-sample test. RESULTS: Most of the relevant studies have investigated and compared changes in spirometric parameters.The median percentage and interquartile range (IQR) of preoperative values in forced vital capacity (FVC), forced expiratory volume in 1 s and forced expiratory flow (FEF) at 25%-75% of FVC (FEF25%-75%) expressed as percentage of their preoperative values 24 h after LC and OC were respectively as follows: [77.6 (73.0, 80.0) L vs 55.4 (50.0, 64.0) L, P < 0.001; 76.0 (72.3, 81.0) L vs 52.5 (50.0, 56.7) L, P < 0.001; and 78.8 (68.8, 80.9) L/s vs 60.0 (36.1, 66.1) L/s, P = 0.005]. Concerning arterial blood gases, partial pressure of oxygen [PaO2 (kPa)] at 24 or 48 h after surgical treatment showed reductions that were significantly

Due to the constant increase of public health awareness and widespread "cancerophobia", the progressively larger number of incidentally diagnosed gall-bladder polyps became the source of anxiety, which leads patients and physicians to undertake therapeutic decisions, despite the absence of symptoms. The majority of gall-bladder polyps are benign. It is estimated that only 3 to 5% of polyps are malignant. Currently, there is lack of randomized control trials based on which the clear-cut criteria of qualification of patients with gall-bladder polyps for surgical procedure can be created. The aim of the study was to analyze gall-bladder polyps in patients who underwent laparoscopic cholecystectomy in the 2nd Department of General Surgery, Jagiellonian University Collegium Medicum. The retrospective study was conducted on 5369 patients who underwent laparoscopic cholecystectomy in the 2nd Department of General Surgery, Jagiellonian University Collegium Medicum with special attention to 152 (2.8%) patients in whom gall-bladder polyps were diagnosed preoperatively. Qualification criteria for surgery, surgical treatment results, and histopathological examination results were also analyzed. Amongst the 5369 patients qualified for laparoscopic cholecystectomy, 152 (2.8%) were diagnosed with gall-bladder polyps during the preoperative ultrasound examinations. Postoperative histopathological examinations of 41 (27%) patients confirmed the presence of gall-bladder polyps. In 102 (67%) patients, only gall-stones were diagnosed without previously described polyps during the ultrasound examination. Analysis of the histopathological examination results revealed the presence of benign lesions in 35 (23.35%) patients. In 5 (3%) patients the presence of an adenoma, and in one (0.65%) the presence of adenocarcinoma were confirmed. Based on the conducted study and previous personal experience in the treatment of patients with gall-bladder polyps, we believe that due to the potential

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.

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 laparoscopic cholecystectomy. The safety and effectiveness of intraperitoneal local anaesthetic instillation in people undergoing laparoscopic cholecystectomy is unknown. To assess the benefits and harms of intraperitoneal instillation of local anaesthetic agents in people undergoing laparoscopic cholecystectomy. We searched the Cochrane Central Register of Controlled Trials (CENTRAL), MEDLINE, EMBASE, and Science Citation Index Expanded 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 local anaesthetic intraperitoneal instillation versus placebo, no intervention, or inactive control during laparoscopic cholecystectomy for the review with regards to benefits while we considered quasi-randomised studies and non-randomised studies for treatment-related harms. 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 58 trials, of which 48 trials with 2849 participants randomised to intraperitoneal local anaesthetic instillation (1558 participants) versus control (1291 participants) contributed data to one or more of the outcomes. All the trials except one trial with 30 participants were at high risk of bias. Most trials included only low anaesthetic risk people undergoing elective laparoscopic cholecystectomy. Various intraperitoneal local anaesthetic agents were used but bupivacaine in the liquid form was the most common local anaesthetic used. There were considerable differences in the methods of local anaesthetic

Nontechnical skills are an essential component of surgical education and a major competency assessed by the ACGME milestones project. However, the optimal way to integrate nontechnical skills training into existing curricula and then objectively evaluate the outcome is still unknown. The aim of this study was to determine the effect laparoscopic team-based task training would have on the nontechnical skills needed for laparoscopic surgery. 9 PGY-1 residents underwent an established training curriculum for teaching the knowledge and technical skills involved in laparoscopic cholecystectomy. Initial training involved a didactic session, expert-led practice on a porcine model in a simulated operating room and laparoscopic skills practice on a virtual reality trainer. Residents then performed a laparoscopic cholecystectomy on the same porcine model as a preintervention test. Three to four months following this, residents were subjected to specific nontechnical skills training involving 2 simple team-based laparoscopic tasks. They then practiced a further 4 to 6 hours on the virtual reality trainer. A repeat postintervention laparoscopic cholecystectomy was then performed 3 to 4 months after nontechnical skills training. Both the preintervention and postintervention laparoscopic cholecystectomies were audiovisually recorded and then evaluated by 2 independent surgeons in a blinded fashion. Technical skills were assessed using objective structured assessment of technical skills (OSATS) and a technique specific rating scale (TRS) that we developed for laparoscopic cholecystectomy. Nontechnical skills were assessed using nontechnical skills for surgeons (NOTSS). Residents also completed a survey at the beginning and end of the training.

Acute calculous cholecystitis represents one of the most common complications of cholelithiasis. While laparoscopic cholecystectomy is the standard treatment in mild and moderate forms, the need for antibiotic therapy after surgery remains undefined. The aim of the randomised controlled Cholecystectomy Antibiotic Randomised Trial (CHART) is therefore to assess if there are benefits in the use of postoperative antibiotics in patients with mild or moderate acute cholecystitis in whom a laparoscopic cholecystectomy is performed. A single-centre, double-blind, randomised trial. After screening for eligibility and informed consent, 300 patients admitted for acute calculus cholecystitis will be randomised into two groups of treatment, either receiving amoxicillin/clavulanic acid or placebo for 5 consecutive days. Postoperative evaluation will take place during the first 30 days. Postoperative infectious complications are the primary end point. Secondary end points are length of hospital stay, readmissions, need of reintervention (percutaneous or surgical reinterventions) and overall mortality. The results of this trial will provide strong evidence to either support or abandon the use of antibiotics after surgery, impacting directly in the incidence of adverse events associated with the use of antibiotics, the emergence of bacterial resistance and treatment costs. This study and informed consent sheets have been approved by the Research Projects Evaluating Committee (CEPI) of Hospital Italiano de Buenos Aires (protocol N° 2111).

First experience with single incision laparoscopic surgery in Slovakia: concomitant cholecystectomy and splenectomy in an 11-year-old girl with hereditary spherocytosis.

Hereditary spherocytosis is an autosomal dominant inheritance disorder of the red blood cell membrane characterized by the presence of spherical-shaped erythrocytes (spherocytes) in the peripheral blood. The main clinical features include haemolytic anemia, variable jaundice, splenomegaly and cholelithiasis caused by hyperbilirubinemia from erythrocyte hemolysis. Splenectomy does not solve the congenital genetic defect but it stops pathological hemolysis in the enlarged spleen. If gallstones are present, it is appropriate to perform cholecystectomy at the time of splenectomy, although the patient has symptoms of gall bladder disease. We present the case of single incision laparoscopic surgical (SILS) concomitant splenectomy and cholecystectomy performed with conventional laparoscopic instruments in an 11-year-old girl with the diagnosis of hereditary spherocytosis. A 2-3 cm umbilical incision was used for the placement of two 5 mm trocars and one 10 mm flexible videoscope. Conventional laparoscopic dissector, grasper, Ligasure, Harmonic Ace and hemoclips were the main tools during surgical procedure. We prefer Single Incision Laparoscopic Surgery Foam Port (Covidien) as the single umbilical device for introduction into the abdominal cavity. First, we performed cholecystectomy, then the gallbladder was put aside over the liver and after that we peformed splenectomy. To remove the detached spleen and gallbladder, a nylon extraction bag is introduced through one of the port sites. The spleen is than morcellated in the bag with forceps and removed in fragments. After that we removed them and the umbilical fascial incision was closed. Splenectomy is the only effective therapy for this disorder and often it is performed in combination with cholecystectomy. Conventional surgery requires a wide upper abdominal incision for correct exposure of the gallbladder and spleen. Our experience shows that SILS splenectomy and cholecystectomy is feasible even in young children and

AIM: To investigate the safety and feasibility of our original single-incision laparoscopic cholecystectomy (SILC) for acute inflamed gallbladder (AIG). METHODS: One hundred and ten consecutive patients underwent original SILC for gallbladder disease without any selection criteria and 15 and 11 of these were diagnosed with acute cholecystitis and acute gallstone cholangitis, respectively. A retrospective review was performed not only between SILC for AIG and non-AIG, but also between SILC for AIG and traditional laparoscopic cholecystectomy (TLC) for AIG in the same period. RESULTS: Comparison between SILC for AIG and non-AIG revealed that the operative time was longer in SILC for AIG (97.5 min vs 85.0 min, P = 0.03). The open conversion rate (2/26 vs 2/84, P = 0.24) and complication rate (1/26 vs 3/84, P = 1.00) showed no differences, but a need for additional trocars was more frequent in SILC for AIG (5/24 vs 3/82, P = 0.01). Comparison between SILC for AIG and TLC for AIG revealed no differences based on statistical analysis. CONCLUSION: Our original SILC technique was adequately safe and feasible for the treatment of acute cholecystitis and acute gallstone cholangitis. PMID:22408354

There are more than 50 different techniques of laparoscopic cholecystectomy (LC) available in literature mainly due to modifications by surgeons in aim to improve postoperative outcome and cosmesis. These modifications include reduction in port size and/or number than what is used in standard LC. There is no uniform nomenclature to describe these different techniques so that it is not possible to compare the outcomes of different techniques. We brief the advantages and disadvantages of each of these techniques and suggest the situation where particular technique would be useful. We also propose a nomenclature which is easy to remember and apply, so that any future comparison will be possible between the techniques. PMID:25883450

OBJECTIVE: This study aimed to reveal the risk factors and outcomes of gallbladder perforation (GP) during laparoscopic cholecystectomy. METHODS: Videotapes of all patients who underwent an elective cholecystectomy at our department were retrospectively analyzed, and the patients were divided into two groups based on the presence of GP. The possible risk factors and early outcomes were analyzed. RESULTS: In total, 664 patients [524 (78.9%) females, 49.7±13.4 years of age] were observed, and GP occurred in 240 (36.1%) patients, mostly while dissecting the gallbladder from its bed (n=197, 82.1%). GP was not recorded in the operation notes in 177 (73.8%) cases. Among the studied parameters, there was no significant risk factor for GP, except preoperatively elevated alanine transaminase level (p=0.005), but the sensitivity and specificity of this measure in predicting GP were 14.2% and 7.4%, respectively. The two groups had similar outcomes, but the operation time (35.4±17.5 vs 41.4±18.7 min, p=0.000) and incidence of drain use (25% vs 45.8%, p=0.000) increased in the GP group. CONCLUSION: The present study reveals that GP occurs in 36.1% of patients who undergo laparoscopic elective cholecystectomy, but it may not be recorded in most cases. We did not find any reliable risk factor that increases the possibility of GP. GP causes an increase in the operation time and incidence of drain use; however, the other outcomes were found to be similar in patients with GP and those without. PMID:29607432

Should laparoscopic cholecystectomy be practiced in the developing world?: the experience of the first training program in Afghanistan.

We address the controversial issue of whether or not it is wise to perform and train laparoscopic cholecystectomy (LC) in a developing nation by reviewing the results of the first large series done in Afghanistan. Afghanistan has been devastated by 3 decades of war leaving it with deficiencies in training programs, medical technologies, and overall medical infrastructure that are among the worst in the developing world. We retrospectively reviewed 137 consecutive cholecystectomies, 102 laparoscopic and 35 open, performed by 4 senior and 3 junior surgeons trained at our hospital in Kabul from July 2005 until February 2008. Deaths, complications, conversion rate, operative time, and hospital length of stay were compared. Unrecognized major operative injuries occurred in 4 LC patients, 3 bile leaks, and 1 duodenal perforation, although there were no such injuries in the open cholecystectomy group. Complication rates were much higher for patients operated on for acute cholecystitis for both surgeon groups. Even though junior surgeons converted to open cholecystectomy more frequently than senior surgeons, they had a higher major complication rate. Hospital length of stay was 28% shorter for the laparoscopic group. The high rate of major unrecognized intraoperative complications during LC in our series underscores the difficulties inherent in performing and training LC in developing nations. Practical changes are suggested to make LC more efficient and safer in a developing world hospital.

AIM: The aim of this study was to evaluate the intraoperative and postoperative complications of laparoscopic cholecystectomy, as well as the frequency of conversions. MATERIAL AND METHODS: Medical records of 740 patients who had laparoscopic cholecystectomy were analysed retrospectively. We evaluated patients for the presence of potential risk factors that could predict the development of complications such as age, gender, body mass index, white blood cell count and C-reactive protein (CRP), gallbladder ultrasonographic findings, and pathohistological analysis of removed gallbladders. The correlation between these risk factors was also analysed. RESULTS: There were 97 (13.1%) intraoperative complications (IOC). Iatrogenic perforations of a gallbladder were the most common complication - 39 patients (5.27%). Among the postoperative complications (POC), the most common ones were bleeding from abdominal cavity 27 (3.64%), biliary duct leaks 14 (1.89%), and infection of the surgical wound 7 patients (0.94%). There were 29 conversions (3.91%). The presence of more than one complication was more common in males (OR = 2.95, CI 95%, 1.42-4.23, p < 0.001). An especially high incidence of complications was noted in patients with elevated white blood cell count (OR = 3.98, CI 95% 1.68-16.92, p < 0.01), and CRP (OR = 2.42, CI 95% 1.23-12.54, p < 0.01). The increased incidence of complications was noted in patients with ultrasonographic finding of gallbladder empyema and increased thickness of the gallbladder wall > 3 mm (OR = 4.63, CI 95% 1.56-17.33, p < 0.001), as well as in patients with acute cholecystitis that was confirmed by pathohistological analysis (OR = 1.75, CI 95% 2.39-16.46, p < 0.001). CONCLUSION: Adopting laparoscopic cholecystectomy as a new technique for treatment of cholelithiasis, introduced a new spectrum of complications. Major biliary and vascular complications are life threatening, while minor complications cause patient discomfort and prolongation of

Approximately 28% of the patients with cystic fibrosis are affected by cholelythiasis. More than 40% of them have a symptomatic disease, which would mandate cholecystectomy. The aim of this study was to review surgical and respiratory outcomes and quality of life scores of cystic fibrosis patients undergoing laparoscopic cholecystectomy for symptomatic cholelythiasis to verify the hypothesis that cholecystectomy is a low-risk operation by laparoscopy, not affecting unfavorably respiratory function and quality of life. Study group was consisted of 9 patients with a mean age of 24.8±8.1 years (range, 15 to 38 y), 2 male and 7 female patients, with cystic fibrosis and symptomatic cholelithiasis. Three patients also presented common bile duct stones. All the patients underwent perioperative Positive End-Expiratory Pressure mask sessions and aggressive antibiotic regimens. At the middle of the antibiotics regimen period, a standard laparoscopic cholecystectomy was performed. In the 3 cases with common duct lithiasis, the so-called "rendezvous" technique was carried out. Preoperatively, intraoperatively, and postoperatively, respiratory function was strictly monitored by the evaluation of SO2 and of the forced expiratory volume in 1 second (FEV1). Preoperatively and 6 months after laparoscopic cholecystectomy the Gastro Intestinal Quality of Life Index was evaluated on all patients. All the operations were completed laparoscopically. No mortality was observed. The intraoperative mean SO2 was 89.0%±5.6% (range, 80% to 95%), versus 82.8%±8.5% (range, 66% to 91%) at the extubation (P=0.006). Intraoperative respiratory functions were stable in 6 patients. In 3 patients, a severe bronchospasm occurred determining marked desaturation. Preoperative mean FEV1 was 70.5%±7.0% (range, 55% to 75%) versus 61.8%±13.2% (range, 39% to 80%) 48 hours after the operation (P=0.132). The 3 patients, who experienced intraoperatively severe bronchospasm, reported a 48 hours postoperative

The revised Tokyo Guidelines include criteria for determining the severity of acute cholecystitis with treatment algorithms based on severity. The aim of this study was to investigate the relationship of the revised Tokyo Guidelines severity grade to clinical outcomes of cholecystectomy for acute cholecystitis. We identified 66 patients with acute cholecystitis from a prior study of difficult cholecystectomy cases. We examined the relationship between severity grade and multiple variables related to perioperative and postoperative outcomes. A more severe revised Tokyo Guidelines grade was associated with a higher number of complications (p = 0.03) and a higher severity of complications (p = 0.01). Severity grade did not predict operative time, estimated blood loss, intensive care unit admission or length of stay. Compared to planned open cholecystectomy, intended laparoscopic cholecystectomy was associated with significantly fewer total and Clavien-Dindo grade 3 complications, fewer intensive care unit admissions, and shorter length of stay (p values range from 0.03 to < 0.0001). In technically difficult operations for acute cholecystitis, the revised Tokyo guidelines severity grade correlates with the number and severity of complications. However, intended performance of laparoscopic cholecystectomy rather than open cholecystectomy in difficult operations predicts broader beneficial outcomes than severity grade.

Background/Aims Gallbladder diseases can give rise to dyspeptic or colonic symptoms in addition to biliary pain. Although most biliary pain shows improvement after cholecystectomy, the fates of dyspeptic or colonic symptoms still remain controversial. This study assessed whether nonspecific gastrointestinal symptoms improved after laparoscopic cholecystectomy (LC) and identified the characteristics of patients who experienced continuing or exacerbated symptoms following surgery. Methods Sixty-five patients who underwent LC for uncomplicated gallbladder stones or gallbladder polyps were enrolled. The patients were surveyed on their dyspeptic or colonic symptoms before surgery and again at 3 and 6 months after surgery. Patients' mental sanity was also assessed using a psychological symptom score with the Symptom Checklist-90-Revised questionnaire. Results Forty-four (67.7%) patients showed one or more dyspeptic or colonic symptoms before surgery. Among these, 31 (47.7%) and 36 (55.4%) patients showed improvement at 3 and 6 months after surgery, respectively. However, 18.5% of patients showed continuing or exacerbated symptoms at 6 months after surgery. These patients did not differ with respect to gallstone or gallbladder polyps, but differed in frequency of gastritis. These patients reported lower postoperative satisfaction. Patients with abdominal symptoms showed higher psychological symptom scores than others. However, poor mental sanity was not related to the symptom exacerbation. Conclusions Elective LC improves dyspeptic or colonic symptoms. Approximately 19% of patients reported continuing or exacerbated symptoms following LC. Detailed history-taking regarding gastritis before surgery can be helpful in predicting patients’ outcome after LC. PMID:24840378

Transvaginal cholecystectomy has been performed successfully at several research institutions worldwide using natural orifice transluminal endoscopic surgery (NOTES) techniques. However, it is a growing new surgical concept in China. Several technical challenges hinder the safe clinical application of NOTES. This study investigated transvaginal endoscopic cholecystectomy performed with the assistance of a single umbilical trocar and achieved helpful initial clinical experience. From May 2009 to April 2010, a total of 43 transvaginal human cholecystectomies were performed. A single umbilical trocar was used for safe access and laparoscopic assistance during the operation. After the gallbladder had been removed through the vagina, the colpotomy was closed with absorbable stitches under direct vision. In addition, Student's t-test was performed for two samples to estimate the superiority of NOTES over a conventional laparoscopic cholecystectomy (LC) operation. The procedure was successfully completed for all the patients. No intra- or post-operative complications occurred. The patients recovered promptly after surgery, and all were satisfied with ideal cosmetic outcomes. The postoperative pain, hospital stay, and cost of hospitalization with NOTES were much less than with conventional LC operations. Although endoscopic instruments specifically designed for NOTES are not available, the addition of an umbilical trocar is an optimal way to allow safe performance of NOTES procedures in an easily reproducible manner. The authors' initial experience demonstrates that this hybrid technique is potentially feasible and effective for reducing postoperative pain and recovery times while improving the cosmetic results of transvaginal cholecystectomy.

AIM: To determine the efficacy of perioperative parecoxib injection on postoperative pain relief after laparoscopic cholecystectomy. METHODS: A prospective, double-blind, randomized, placebo-controlled study was conducted on 70 patients who underwent elective laparoscopic cholecystectomy under general anesthesia at Siriraj Hospital, Bangkok, from January 2006 to December 2007. Patients were randomized to receive either 20 mg parecoxib infusion 30 min before induction of anesthesia and at 12 h after the first dose (treatment group), or normal saline infusion, in the same schedule, as a placebo (control group). The degree of the postoperative pain was assessed every 3 h in the first 24 h after surgery, and then every 12 h the following day, using a visual analog scale. The consumption of analgesics was also recorded. RESULTS: There were 40 patients in the treatment group, and 30 patients in the control group. The pain scores at each time point, and analgesic consumption did not differ between the two groups. However, there were fewer patients in the treatment group than placebo group who required opioid infusion within the first 24 h (60% vs 37%, P = 0.053). CONCLUSION: Perioperative administration of parecoxib provided no significant effect on postoperative pain relief after laparoscopic cholecystectomy. However, preoperative infusion 20 mg parecoxib could significantly reduce the postoperative opioid consumption. PMID:19399934

Fibromyalgia, a chronic syndrome of diffuse musculoskeletal pain and somatic hyperalgesia from central sensitization, is very often comorbid with visceral pain conditions. In fibromyalgia patients with gallbladder calculosis, this study assessed the short and long-term impact of laparoscopic cholecystectomy on fibromyalgia pain symptoms. Fibromyalgia pain (VAS scale) and pain thresholds in tender points and control areas (skin, subcutis and muscle) were evaluated 1week before (basis) and 1week, 1,3,6 and 12months after laparoscopic cholecystectomy in fibromyalgia patients with symptomatic calculosis (n = 31) vs calculosis patients without fibromyalgia (n. 26) and at comparable time points in fibromyalgia patients not undergoing cholecystectomy, with symptomatic (n = 27) and asymptomatic (n = 28) calculosis, and no calculosis (n = 30). At basis, fibromyalgia+symptomatic calculosis patients presented a significant linear correlation between the number of previously experienced biliary colics and fibromyalgia pain (direct) and muscle thresholds (inverse)(p<0.0001). After cholecystectomy, fibromyalgia pain significantly increased and all thresholds significantly decreased at 1week and 1month (1-way ANOVA, p<0.01-p<0.001), the decrease in muscle thresholds correlating linearly with the peak postoperative pain at surgery site (p<0.003-p<0.0001). Fibromyalgia pain and thresholds returned to preoperative values at 3months, then pain significantly decreased and thresholds significantly increased at 6 and 12months (p<0.05-p<0.0001). Over the same 12-month period: in non-fibromyalgia patients undergoing cholecystectomy thresholds did not change; in all other fibromyalgia groups not undergoing cholecystectomy fibromyalgia pain and thresholds remained stable, except in fibromyalgia+symptomatic calculosis at 12months when pain significantly increased and muscle thresholds significantly decreased (p<0.05-p<0.0001).

2012-01-01

Background Laparoscopic cholecystectomy in acute calculous cholecystitis in high risk patients can lead to significant morbidity and mortality. Percutaneous cholecystostomy may be an alternative treatment option but the current literature does not provide the surgical community with evidence based advice. Methods/Design The CHOCOLATE trial is a randomised controlled, parallel-group, superiority multicenter trial. High risk patients, defined as APACHE-II score 7-14, with acute calculous cholecystitis will be randomised to laparoscopic cholecystectomy or percutaneous cholecystostomy. During a two year period 284 patients will be enrolled from 30 high volume teaching hospitals. The primary endpoint is a composite endpoint of major complications within three months following randomization and need for re-intervention and mortality during the follow-up period of one year. Secondary endpoints include all other complications, duration of hospital admission, difficulty of procedures and total costs. Discussion The CHOCOLATE trial is designed to provide the surgical community with an evidence based guideline in the treatment of acute calculous cholecystitis in high risk patients.

To evaluate and compare intercostal-iliac transversus abdominis plane (TAP) and oblique subcostal TAP (OSTAP) blocks for multimodal analgesia in patients receiving laparoscopic cholecystectomy. A prospective, randomized, double-blinded clinical study. Operating room, postoperative recovery area, and ward. In total, 60 laparoscopic cholecystectomy patients (43 women, 17 men, American Society of Anesthesiologists grades I-II) were enrolled from the general surgery department of our tertiary care center. The patients were assigned to 1 of the 3 groups. Group 1 received TAP blocks (n=20), group 2 received OSTAP blocks (n=20), and group 3 patients were used as controls and received patient-controlled analgesia (PCA) only (n=20). After the induction of anesthesia, blocks were performed bilaterally in study groups 1 and 2, using 20mL of lidocaine (5mg/mL). PCA with intravenous tramadol was routinely provided for all patients during the first 24hours. The intraoperative use of remifentanil, postoperative visual analog scale (VAS) scores, demand for PCA, and total analgesic consumption were recorded. The patients in the control group had greater analgesic demands and analgesic consumption than did those in groups 1 and 2. However, patients in the OSTAP group had lower VAS scores than did those in groups 1 and 3. The demand for analgesia was greater in the control group than in groups 1 and 2. Moreover, lower VAS scores were recorded in the OSTAP group than in groups 1 and 3 and were positively correlated with total PCA consumption among all patients. However, postoperative VAS scores were negatively correlated with the total intraoperative consumption of remifentanil at 24hours. TAP and OSTAP blocks improved postoperative analgesia in patients receiving laparoscopic cholecystectomy, which resulted in lower VAS scores and reduction in total analgesic consumption.

Single-port laparoscopic cholecystectomy (LC) has been compared with 3- or 4-port LC. To our knowledge, there are no studies comparing the 3-, 2-, and 1-port techniques. Patients were randomized into 3 groups: LC 1-port using SILS, LC 2-port using a laparoscope with a working channel, and LC 3-port using the standard ports. Pain was evaluated at recovery, 4 hours, 24 hours, day 5, and day 8, using an analog visual scale. Homogenous groups in their demographic characteristics; all confirmed gallbladder lithiasis. At recovery, there was less pain in group 1 (P = 0.002); at 4 hours pain was similar in all groups (P = 0.899); at 24 hours there was less pain in groups 2 and 3 (P = 0.031); and at days 5 and 8 there was marginal (P = 0.053) and significant (P = 0.003) relevance. In terms of pain perception, LC performed through 1 port does not offer advantages when compared with 2 or 3 ports. More clinical trials are needed to confirm these data. PMID:25437581

Cirrhotic patients have been known to be more affected with gallstones than their non-cirrhotic counterparts; since laparoscopy was introduced, it has been generally approved as the standard approach for cholecystectomies with the exception of end-stage cirrhosis. The purpose of this study was to evaluate the safety and efficacy of clipless laparoscopic cholecystectomy using the harmonic scalpel in complicated cholelithiasis in cirrhotic patients. This prospective study was conducted on 62 cirrhotic patients presenting to the Gastrointestinal Surgery Unit in Alexandria Main University Hospital with complicated gallstones between March 2013 and March 2016. Both intraoperative time and blood loss were calculated in addition to rates of conversion to open cholecystectomy, morbidity and mortality. Most of our cases were females with a ratio of 1.7:1, with a mean age of 45.21 years, ranging from 25 to 65 years. The most common cause of cirrhotic liver was hepatitis C in 45.1% of patients. Among the 62 patients included in the study, 56 patients (90.3%) were presenting with acute cholecystitis and six patients were operated at the onset of acute biliary pancreatitis. The mean operative time was 72.9 min with mean blood loss 45.45 mL. The study concluded safety of total clipless laparoscopic cholecystectomy using a harmonic scalpel in Child A and B type cirrhotic patients, who presented with complicated gallstones. © 2017 Royal Australasian College of Surgeons.

A source of frustration during laparoscopic cholecystectomy involves extraction of the gallbladder through port sites smaller than the gallbladder itself. We describe the development and testing of a novel device for the safe, minimal enlargement of laparoscopic port sites to extract large, stone-filled gallbladders from the abdomen. The study device consists of a handle with a retraction tongue to shield the specimen and a guide for a scalpel to incise the fascia within the incision. Patients enrolled underwent laparoscopic cholecystectomy. Gallbladder extraction was attempted. If standard measures failed, the device was implemented. Extraction time and device utility scores were recorded for each patient. Patients returned 3-4 weeks postoperatively for assessment of pain level, cosmetic effect, and presence of infectious complications. Twenty (51 %) of 39 patients required the device. Average extraction time for the first eight patients was 120 s. After interim analysis, an improved device was used in 12 patients and average extraction time was 24 s. There were no adverse events. Postoperative pain ratings and incision cosmesis were comparable between patients with and without use of the device. The study device enables safe and rapid extraction of impacted gallbladders through the abdominal wall.

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.

A systematic review to determine whether skills acquired through simulation-based training transfer to the operating room for the procedures of laparoscopic cholecystectomy and endoscopy. Simulation-based training assumes that skills are directly transferable to the operation room, but only a few studies have investigated the effect of simulation-based training on surgical performance. A systematic search strategy that was used in 2006 was updated to retrieve relevant studies. Inclusion of articles was determined using a predetermined protocol, independent assessment by 2 reviewers, and a final consensus decision. Seventeen randomized controlled trials and 3 nonrandomized comparative studies were included in this review. In most cases, simulation-based training was in addition to patient-based training programs. Only 2 studies directly compared simulation-based training in isolation with patient-based training. For laparoscopic cholecystectomy (n = 10 studies) and endoscopy (n = 10 studies), participants who reached simulation-based skills proficiency before undergoing patient-based assessment performed with higher global assessment scores and fewer errors in the operating room than their counterparts who did not receive simulation training. Not all parameters measured were improved. Two of the endoscopic studies compared simulation-based training in isolation with patient-based training with different results: for sigmoidoscopy, patient-based training was more effective, whereas for colonoscopy, simulation-based training was equally effective. Skills acquired by simulation-based training seem to be transferable to the operative setting for laparoscopic cholecystectomy and endoscopy. Future research will strengthen these conclusions by evaluating predetermined competency levels on the same simulators and using objective validated global rating scales to measure operative performance.

Percutaneous transhepatic gallbladder drainage (PTGBD) is a procedure to resolve acute cholecystitis (AC). It may decrease the technical difficulty of laparoscopic cholecystectomy (LC) and thus may facilitate successful surgery when a patients' condition improves. However, the timing of LC after PTGBD remains controversial. From 2004 to 2010, cholecystectomy after PTGBD was performed in 67 patients with AC. Group I members underwent LC within 72 h of PTGBD (n = 21), whereas group II members underwent LC at more than 72 h after PTGBD (n = 46). The open conversion rate was similar in the two groups. The perioperative complication rate was higher in group I than in group II, but with marginal significance (19.0 vs. 4.3%; p = 0.07). Mean operative time was longer in group I than in group II (79.3 ± 25.3 vs. 53.7 ± 45.3 min; p = 0.02). However, overall hospital stay was shorter in group I than in group II, but with marginal significance (10.8 ± 4.5 vs. 14.7 ± 9.3 days; p = 0.08). Pros and cons were well balanced between the two groups. Decisions on the timing of cholecystectomy after PTGBD should be made based on considerations of patient condition, hospital facilities, and surgical experience.

Single port laparoscopic surgery has come to the forefront of minimally invasive surgery. For those familiar with conventional techniques, however, this type of operation demands a different type of eye/hand coordination and involves unfamiliar working instruments. Herein, the authors describe the learning curve and the clinical outcomes of single port laparoscopic cholecystectomy for 150 consecutive patients with benign gallbladder disease. All patients underwent single port laparoscopic cholecystectomy using a homemade glove port by one of five operators with different levels of experiences of laparoscopic surgery. The learning curve for each operator was fitted using the non-linear ordinary least squares method based on a non-linear regression model. Mean operating time was 77.6 ± 28.5 min. Fourteen patients (6.0%) were converted to conventional laparoscopic cholecystectomy. Complications occurred in 15 patients (10.0%), as follows: bile duct injury (n = 2), surgical site infection (n = 8), seroma (n = 2), and wound pain (n = 3). One operator achieved a learning curve plateau at 61.4 min per procedure after 8.5 cases and his time improved by 95.3 min as compared with initial operation time. Younger surgeons showed significant decreases in mean operation time and achieved stable mean operation times. In particular, younger surgeons showed significant decreases in operation times after 20 cases. Experienced laparoscopic surgeons can safely perform single port laparoscopic cholecystectomy using conventional or angled laparoscopic instruments. The present study shows that an operator can overcome the single port laparoscopic cholecystectomy learning curve in about eight cases.

The usefulness of percutaneous needles (PN) to replace traditional assistance ports in mini-invasive techniques with a single port is analyzed and their feasibility for conducting a single port laparoscopic cholecystectomy (SPLC) is demonstrated. A retrospective, linear and descriptive study covering 2,431 patients with a diagnosis of acute and non-acute gallbladder disease has been conducted. The patients underwent a single port laparoscopic cholecystectomy using some type of PNs, replacing the assisting ports used in traditional laparoscopic cholecystechtomy (TLC). Based on the progressive use of PNs-reins (R), hooked needles (HN) and passing suture needles (PSN)-to carry out the SPLC technique, 3 groups have been established: A, B and C. The results were compared using a Student T test, odds ratio and CI and were analyzed by means of the SPSS software v. 13.0. The use of PNs showed an increased feasibility for the laparoscopic procedure, as they were included in the surgical technique. The R were useful when carrying out the SPLC in 78% of the cases and when the HK were added, the results increased to 88%. When using the 3 types (R, HN and PSN), the results increased by 96%. Statistical significance was obtained with these values: chi 2=67.13 and P<.001; odds ratio and 95% CI became significant when comparing the B/C, A/C, and A-B/C groups. The PNs, replacing the assisting ports in laparoscopy, make it possible to attain a feasibility of the process in 96% of the cases. This percentage was similar to what is achieved with the TLC, which places the one port laparoscopy surgery technique as an advantageous and economic alternative. This application of the PNs could be made extensive to other single-port techniques, with a multi-valve platform and natural orifice surgery. Copyright © 2012 AEC. Published by Elsevier Espana.

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.

Objectives Single-incision laparoscopic cholecystectomy (SILC) may be associated with less pain, shorter hospital stay and better cosmetic results than multiport laparoscopic cholecystectomy (MLC). Advocates suggest that patients prefer SILC, although research directly addressing the question of patient preferences is limited. This study aimed to assess patient preferences using currently available evidence. Methods Patients awaiting elective cholecystectomy were shown a series of postoperative images taken after SILC or MLC and asked which procedure this led them to prefer. This was repeated after patients had completed a questionnaire constructed using published objective data comparing patient-reported outcomes of SILC and MLC. Results The study was completed by 113 consecutive patients. After their initial viewing of the images, 16% of subjects preferred MLC. Younger age, lower body mass index and female sex were associated with choosing SILC. After completing the questionnaire, 88% of patients preferred MLC (P < 0.001). Patients ranked the level of risk for complications and postoperative pain above cosmetic results in determining their choice of procedure. Conclusions Patients' initial preference when presented with cosmetic appearance was for SILC. When contemporary outcome data were included, the majority chose MLC. This underlines the need to fully inform patients during the consent process and indicates that patient views of SILC may differ from the views of those introducing the technology. PMID:22404262

Pain control after a laparoscopic cholecystectomy can represent a challenge, considering the side effects due to standard analgesia methods. Recently the transversus abdominis plane block (TAP Block) has been used as a part of multimodal analgesia with promising results. The subcostal approach (OSTAP Block), a variant on the TAP block, produces reliable unilateral supraumbilical analgesia. This study evaluated the efficacy of the OSTAP block with bupivacaine in laparoscopic cholecystectomy compared with the placebo OSTAP block. Sixty ASA I/II adult patients listed for elective laparoscopic cholecystectomy were randomly allocated in one of two groups: Group A (OSTAP placebo) received preoperatively bilateral OSTAP block with sterile normal saline and Group B (OSTAP bupivacaine) received bilateral preoperatively OSTAP block with the same volumes of 0.25% bupivacaine. Twenty-four hours postoperative opioid consumption, the dose of opioid required during surgery, opioid dose in the recovery unit (PACU) and PACU length of stay were evaluated. The quality of analgesia was assessed by the Visual Analogue Scale (VAS) at specific interval hours during 24 h, at rest and with movement. The mean intraoperative opioid consumption showed a significant difference between the two groups, (385 ± 72.52 mg in group A vs 173.67 ± 48.60 mg in group B, p < 0.001). The mean 24 h opioid consumption showed a statistically significant difference between groups (32 ± 26.05 mg vs 79 ± 16.68 mg, p < 0.001). PACU length of stay was significantly lower for group B patients compared with group A patients (20.67 ± 11.27 min vs 41.67 ± 12.41 min, p < 0.001). The OSTAP bupivacaine group had a statistically significant lower pain score than the OSTAP placebo group at 0, 2, 4, 6, 12, 24 h, both at rest and with movement. No signs or symptoms of local anaesthetic systemic toxicity or other complications were detected. OSTAP block with bupivacaine 0.25% can provide effective analgesia up to 24

Abstract Background. There are limited data on risk factors for surgical site infection (SSI) after open or laparoscopic cholecystectomy. Methods. A retrospective cohort of commercially insured persons aged 18–64 years was assembled using International Classification of Diseases, 9th Revision, Clinical Modification (ICD-9-CM) procedure or Current Procedural Terminology, 4th edition codes for cholecystectomy from December 31, 2004 to December 31, 2010. Complex procedures and patients (eg, cancer, end-stage renal disease) and procedures with pre-existing infection were excluded. Surgical site infections within 90 days after cholecystectomy were identified by ICD-9-CM diagnosis codes. A Cox proportional hazards model was used to identify independent risk factors for SSI. Results. Surgical site infections were identified after 472 of 66566 (0.71%) cholecystectomies; incidence was higher after open (n = 51, 4.93%) versus laparoscopic procedures (n = 421, 0.64%; P < .001). Independent risk factors for SSI included male gender, preoperative chronic anemia, diabetes, drug abuse, malnutrition/weight loss, obesity, smoking-related diseases, previous Staphylococcus aureus infection, laparoscopic approach with acute cholecystitis/obstruction (hazards ratio [HR], 1.58; 95% confidence interval [CI], 1.27–1.96), open approach with (HR, 4.29; 95% CI, 2.45–7.52) or without acute cholecystitis/obstruction (HR, 4.04; 95% CI, 1.96–8.34), conversion to open approach with (HR, 4.71; 95% CI, 2.74–8.10) or without acute cholecystitis/obstruction (HR, 7.11; 95% CI, 3.87–13.08), bile duct exploration, postoperative chronic anemia, and postoperative pneumonia or urinary tract infection. Conclusions. Acute cholecystitis or obstruction was associated with significantly increased risk of SSI with laparoscopic but not open cholecystectomy. The risk of SSI was similar for planned open and converted procedures. These findings suggest that stratification by operative factors is

Laparoscopic cholecystectomies are associated with an appreciably high rate of postoperative nausea and vomiting (PONV). This study was designed to compare the effectiveness of ondansetron, granisetron, and dexamethasone for the prevention of PONV in patients after laparoscopic cholecystectomy. A total of 80 American Society of Anesthesiologists (ASA) physical class I-II patients scheduled for laparoscopic cholecystectomy were included in this randomized, double blind, placebo-controlled study. All patients received a similar standardized anesthesia and operative treatment. Patients were randomly divided into four groups (n = 20 each). Group 1, consisting of control patients, received 0.9% NaCl; group 2 patients received ondansetron 4 mg i.v.; group 3 patients received granisetron 3 mg i.v.; and group 4 patients received dexamethasone 8 mg i.v., all before the induction of anesthesia. Both nausea and vomiting were assessed during the first 24 h after the procedure. The total incidence of PONV was 75% with placebo, 35% with ondansetron, 30% with granisetron, and 25% with dexamethasone. The incidence of PONV was significantly less frequent in groups receiving antiemetics (p < 0.05). The differences between dexamethasone, granisetron, and ondansetron were not significant. Prophylactic dexamethasone 8 mg i.v. significantly reduced the incidence of PONV in patients undergoing laparoscopic cholecystectomy. Dexamethasone 8 mg was as effective as ondansetron 4 mg and granisetron 3 mg, and it was more effective than placebo.

To determine if pager interruptions affect operative time, safety, or complications and management of pager issues during a simulated laparoscopic cholecystectomy. Twelve surgery resident volunteers were tested on a Simbionix Lap Mentor II simulator. Each resident performed 6 randomized simulated laparoscopic cholecystectomies; 3 with pager interruptions (INT) and 3 without pager interruptions (NO-INT). The pager interruptions were sent in the form of standardized patient vignettes and timed to distract the resident during dissection of the critical view of safety and clipping of the cystic duct. The residents were graded on a pass/fail scale for eliciting appropriate patient history and management of the pager issue. Data was extracted from the simulator for the following endpoints: operative time, safety metrics, and incidence of operative complications. The Mann-Whitney U test and contingency table analysis were used to compare the 2 groups (INT vs. NO-INT). Level I trauma center; Simulation laboratory. Twelve general surgery residents. There was no significant difference between the 2 groups in any of the operative endpoints as measured by the simulator. However, in the INT group, only 25% of the time did the surgery residents both adequately address the issue and provide effective patient management in response to the pager interruption. Pager interruptions did not affect operative time, safety, or complications during the simulated procedure. However, there were significant failures in the appropriate evaluations and management of pager issues. Consideration for diversion of patient care issues to fellow residents not operating to improve quality and safety of patient care outside the operating room requires further study. Copyright © 2018.

Automatic PSO-Based Deformable Structures Markerless Tracking in Laparoscopic Cholecystectomy

NASA Astrophysics Data System (ADS)

Djaghloul, Haroun; Batouche, Mohammed; Jessel, Jean-Pierre

An automatic and markerless tracking method of deformable structures (digestive organs) during laparoscopic cholecystectomy intervention that uses the (PSO) behavour and the preoperative a priori knowledge is presented. The associated shape to the global best particles of the population determines a coarse representation of the targeted organ (the gallbladder) in monocular laparoscopic colored images. The swarm behavour is directed by a new fitness function to be optimized to improve the detection and tracking performance. The function is defined by a linear combination of two terms, namely, the human a priori knowledge term (H) and the particle's density term (D). Under the limits of standard (PSO) characteristics, experimental results on both synthetic and real data show the effectiveness and robustness of our method. Indeed, it outperforms existing methods without need of explicit initialization (such as active contours, deformable models and Gradient Vector Flow) on accuracy and convergence 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.

Recent studies have suggested higher complication and conversion to open rates for nighttime laparoscopic cholecystectomy (LC) and recommend against the practice. We hypothesize that patients undergoing night LC for acute cholecystitis have decreased hospital length of stay and cost with no difference in complication and conversion rates. A retrospective review of patients with acute cholecystitis who underwent LC from October 2011 through June 2015 was performed. Complication rates, length of stay, and cost of hospitalization were compared between patients undergoing day cholecystectomy and night cholecystectomy. Complication rates and costs did not differ between the day and night groups. Length of stay was shorter in the night group (2.4 vs 2.8 days, p = 0.002). Performing LC for acute cholecystitis during night-time hours does not increase risk of complications and decreases length of stay. Copyright © 2017 Elsevier Inc. All rights reserved.

Outpatient laparoscopic cholecystectomy is a safe procedure and provides a better use of health resources and perceived satisfaction without affecting quality of care. Preoperative education has shown less postoperative stress, pain and nausea in some interventions. The principal objective of this study is to assess the impact of preoperative education on postoperative pain in patients undergoing ambulatory laparoscopic cholecystectomy. Secondary objectives were: to evaluate presence of nausea, morbidity, hospital admissions, readmissions rate, quality of life and satisfaction. Prospective, randomized, and double blind study. Between April 2014 and May 2016, 62 patients underwent outpatient laparoscopic cholecystectomy. ASA I-II, age 18-75, outpatient surgery criteria, abdominal ultrasonography with cholelithiasis. Patient randomization in two groups, group A: intensified preoperative education and group B: control. Sixty-two patients included, 44 women (71%), 18 men (29%), mean age 46,8 years (20-69). Mean BMI 27,5. Outpatient rate 92%. Five cases required admission, two due to nausea. Pain scores obtained using a VAS was at 24-hour, 2,9 in group A and 2,7 in group B. There were no severe complications or readmissions. Results of satisfaction and quality of life scores were similar for both groups. We did not find differences due to intensive preoperative education. However, we think that a correct information protocol should be integrated into the patient's preoperative preparation.

Morpho-functional gastric pre-and post-operative changes in elderly patients undergoing laparoscopic cholecystectomy for gallstone related disease

PubMed Central

2012-01-01

Background Cholecystectomy, gold standard treatment for gallbladder lithiasis, is closely associated with increased bile reflux into the stomach as amply demonstrated by experimental studies. The high prevalence of gallstones in the population and the consequent widespread use of surgical removal of the gallbladder require an assessment of the relationship between cholecystectomy and gastric mucosal disorders. Morphological evaluations performed on serial pre and post – surgical biopsies have provided new acquisitions about gastric damage induced by bile in the organ. Methods 62 elderly patients with gallstone related disease were recruited in a 30 months period. All patients were subjected to the most appropriate treatment (Laparoscopic cholecystectomy). The subjects had a pre-surgical evaluation with: • dyspeptic symptoms questionnaire, • gastric endoscopy with body, antrum, and fundus random biopsies, • histo-pathological analysis of samples and elaboration of bile reflux index (BRI). The same evaluation was repeated at a 6 months follow-up. Results In our series the duodeno-gastric reflux and the consensual biliary gastritis, assessed histologically with the BRI, was found in 58% of the patients after 6 months from cholecystectomy. The demonstrated bile reflux had no effect on H. pylori’s gastric colonization nor on the induction of gastric precancerous lesions. Conclusions Cholecystectomy, gold standard treatment for gallstone-related diseases, is practiced in a high percentage of patients with this condition. Such procedure, considered by many harmless, was, in our study, associated with a significant risk of developing biliary gastritis after 6 months during the postoperative period. PMID:23173777

Single-incision laparoscopic cholecystectomy evolved from the traditional multiport laparoscopic technique. Prior trials have demonstrated improved cosmesis with the single-incision technique. Robotic single-site surgery minimizes the technical difficulties associated with laparoscopic single-incision approach. This is the first prospective, randomized, controlled study comparing robotic single-site cholecystectomy (RSSC) and multiport laparoscopic cholecystectomy (MPLC) in terms of cosmesis and patient satisfaction. Patients with symptomatic benign gallbladder disease were randomized to RSSC or MPLC. Data included perioperative variables such as operative time, conversion and complications and cosmesis satisfaction, body image perception, quality of life using validated questionnaires, at postoperative visits of 2, 6 weeks and 3 months. One hundred thirty-six patients were randomized to RSSC (N = 83) and MPLC (N = 53) at 8 institutions. Both cohorts were dominated by higher enrollment of females (RSSC = 78%, MPLC = 92%). The RSSC and MPLC cohorts were otherwise statistically matched. Operative time was longer for RSSC (61 min vs. 44 min, P < 0.0001). There were no differences in complication rates. RSSC demonstrated a significant superiority in cosmesis satisfaction and body image perception (P value < 0.05 at every follow-up). There was no statistically significant difference in patient-reported quality of life. Multivariate analysis of female patients demonstrated significantly higher preference for RSSC over MPLC in cosmesis satisfaction and body image perception with no difference seen in overall quality of life. Results from this trial show that RSSC is associated with improved cosmesis satisfaction and body image perception without a difference in observed complication rate. The uncompromised safety and the improved cosmesis satisfaction and body image perception provided by RSSC for female patients support consideration of the robotic single

Laparoscopic cholecystectomy has become the "gold standard" for cholelithiasis. In laparoscopic technique, the incidence and the severity of injuries of the extrahepatic bile ducts are significantly higher (0-2,7%) than in open surgery (0,2-0,5%). The authors present a series of 18 patients with such lesions, operated between 1996 and 2005 in the surgical departments of 2 Clinical Hospitals: "Dr.I.Cantacuzino" and Coltea, from Bucharest. The injuries were: 2--of type A, 10--of type D and 6--of type E, according to Soper-Strasberg classification. There are analysed the causes and the circumstances in which these injuries have occurred, the clinical signs and imagistic findings and, most of all, their treatment. In complete transections of the common bile duct, a hepatico-jejuno-anastomosis using a Roux en Y-loop appears to be the best solution. It is emphasized the fact that an accurate diagnosis and surgical technique are essential for a favourable evolution. That's why these operations must be accomplished by experimented surgeons, from highly specialized departments.

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.

To study the bacteriological profile, and to determine predictors of bile infection and septic complications following laparoscopic cholecystectomy. This cross-sectional study reviewed 1248 laparoscopic cholecystectomy cases performed between January 1994 and December 2007 by one surgical team at the Jordan University Hospital, Amman, Jordan. Bile cultures were performed for all patients and statistical analysis was performed on culture results and postoperative complications as well as, on the possible predictors of bile infection including age, gender, associated diseases, preoperative retrograde cholangiopancreatography (ERCP), and indications for surgery. Uncomplicated gallstone disease was diagnosed in 993 patients (79.6%), 221 patients (17.7%) had acute cholecystitis, and 34 patients (2.7%) had jaundice. Associated morbidities were present in 513 patients (41.1%), preoperative ERCP was performed for 132 patients (10.6%), and postoperative septic complications developed in 25 patients (2%). Bile culture was positive in 250 patients (20%), 134 (53.6%) of whom had gram negative bacteria, 73 (29.2%) had gram positive bacteria, and 43 (17.2%) had mixed cultures. The chi-square test has shown that positive bile culture is significantly associated with age, gender, preoperative ERCP, associated morbidities, and complicated gallbladder disease, whereas multinomial regression analysis has shown that age and preoperative ERCP were the only significant predictors of bile infection. Bile infection commonly complicates gallstone disease, and it can be influenced by age and preoperative endoscopic interventions, but it does not influence the occurrence of postoperative septic complications.

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.

Recent advances in robotic technology suggest that the utilization of the da Vinci Single-Site™ platform for cholecystectomy is safe, feasible and results in a shorter learning curve compared to conventional single-incision laparoscopic cholecystectomy. Moreover, the robot-assisted technology has been shown to reduce the surgeon's stress load compared to standard single-incision laparoscopy in an experimental setup, suggesting an important advantage of the da Vinci platform. However, the above-mentioned observations are based solely on case series, case reports and experimental data, as high-quality clinical trials to demonstrate the benefits of the da Vinci Single-Site™ cholecystectomy have not been performed to date. This study addresses the question whether robot-assisted Single-Site™ cholecystectomy provides significant benefits over single-incision laparoscopic cholecystectomy in terms of surgeon's stress load, while matching the standards of the conventional single-incision approach with regard to peri- and postoperative outcomes. It is designed as a single centre, single-blinded randomized controlled trial, which compares both surgical approaches with the primary endpoint surgeon's physical and mental stress load at the time of surgery. In addition, the study aims to assess secondary endpoints such as operating time, conversion rates, additional trocar placement, intra-operative blood loss, length of hospital stay, costs of procedure, health-related quality of life, cosmesis and complications. Patients as well as ward staff are blinded until the 1 st postoperative year. Sample size calculation based on the results of a previously published experimental setup utilizing an estimated effect size of surgeon's comfort of 0.8 (power of 0.8, alpha-error level of 0.05, error margin of 10-15%) resulted in a number of 30 randomized patients per arm. The study is the first randomized controlled trial that compares the da Vinci Single Site™ platform to

Background NOTES is an emerging technique for performing surgical procedures, such as cholecystectomy. Debate about its real benefit over the traditional laparoscopic technique is on-going. There have been several clinical studies comparing NOTES to conventional laparoscopic surgery. However, no work has been done to compare these techniques from a Human Factors perspective. This study presents a systematic analysis describing and comparing different existing NOTES methods to laparoscopic cholecystectomy. Methods Videos of endoscopic/laparoscopic views from fifteen live cholecystectomies were analyzed to conduct a detailed task analysis of the NOTES technique. A hierarchical task analysis of laparoscopic cholecystectomy and several hybrid transvaginal NOTES cholecystectomies was performed and validated by expert surgeons. To identify similarities and differences between these techniques, their hierarchical decomposition trees were compared. Finally, a timeline analysis was conducted to compare the steps and substeps. Results At least three variations of the NOTES technique were used for cholecystectomy. Differences between the observed techniques at the substep level of hierarchy and on the instruments being used were found. The timeline analysis showed an increase in time to perform some surgical steps and substeps in NOTES compared to laparoscopic cholecystectomy. Conclusion As pure NOTES is extremely difficult given the current state of development in instrumentation design, most surgeons utilize different hybrid methods – combination of endoscopic and laparoscopic instruments/optics. Results of our hierarchical task analysis yielded an identification of three different hybrid methods to perform cholecystectomy with significant variability amongst them. The varying degrees to which laparoscopic instruments are utilized to assist in NOTES methods appear to introduce different technical issues and additional tasks leading to an increase in the surgical time.

Objective To report a single-incision laparoscopic cholecystectomy (SILC) for a patient with cholecystitis that required endoscopic nasogallbladder drainage (ENGBD). Clinical Presentation and Intervention A 75-year-old man was diagnosed with moderate acute cholecystitis and underwent antiplatelet therapy for a history of brain infarction. An ENGBD was performed as an initial treatment for his cholecystitis. After recovery from the cholecystitis, a SILC was performed using a SILS Port with an additional forceps. Because neither Rouviere's sulcus nor Calot's triangle could be identified with a favorable laparoscopic view, the fundus-first procedure was selected. The patient's postoperative course was uneventful, and he was discharged from the hospital on day 3 after surgery. Conclusion In this case of a patient who had cholecystitis that required ENGBD, a SILC was successful performed using a combination of SILS Port with additional forceps and fundus-first procedure.

Purpose The purpose of this study was to analyze the educational quality of laparoscopic cholecystectomy (LC) videos accessible on YouTube, one of the most important sources of internet-based medical information. Methods The keyword 'laparoscopic cholecystectomy' was used to search on YouTube and the first 100 videos were analyzed. Among them, 27 videos were excluded and 73 videos were included in the study. An arbitrary score system for video quality, devised from existing LC guidelines, were used to evaluate the quality of the videos. Video demographics were analyzed by the quality and source of the video. Correlation analysis was performed. Results When analyzed by video quality, 11 (15.1%) were evaluated as 'good', 40 (54.8%) were 'moderate', and 22 (30.1%) were 'poor', and there were no differences in length, views per day, or number of likes, dislikes, and comments. When analyzed by source, 27 (37.0%) were uploaded by primary centers, 20 (27.4%) by secondary centers, 15 (20.5%) by tertiary centers, 5 (6.8%) by academic institutions, and 6 (8.2%) by commercial institutions. The mean score of the tertiary center group (6.0 ± 2.0) was significantly higher than the secondary center group (3.9 ± 1.4, P = 0.001). The video score had no correlation with views per day or number of likes. Conclusion Many LC videos are accessible on YouTube with varying quality. Videos uploaded by tertiary centers showed the highest educational value. This discrepancy in video quality was not recognized by viewers. More videos with higher quality need to be uploaded, and an active filtering process is necessary. PMID:26236699

Background and Objectives: Until the advent of single-incision laparoscopic surgery, few advances were aimed at improving cosmesis with laparoscopic cholecystectomy. Criticisms of the single-incision laparoscopic surgery technique include a larger incision and increased incidence of wound-related complications. We present our initial experience with a novel technique aimed at performing strategic laparoscopy for improved cosmesis (SLIC) for cholecystectomy. Methods: Twenty-five patients with biliary symptoms were selected for SLIC cholecystectomy. Access to the abdomen was obtained with a 5-mm optical trocar in the left upper quadrant and a 5-mm trocar in the umbilicus. Retraction was performed by a transabdominal suture in the dome of the gallbladder and a needlescopic grasper. Age, American Society of Anesthesiologists score, body mass index, operative time, length of stay, pathology results, and short-term complications at follow-up were prospectively recorded. Results: The 25 female patients had a mean age of 34.3 years and mean body mass index of 24 kg/m2. American Society of Anesthesiologists scores ranged from 1 to 3. The mean operative time was 51.3 minutes. Pathology revealed chronic cholecystitis in all patients. All procedures were performed on an outpatient basis. The only complication was one ultrasonography-documented deep vein thrombosis. All 25 planned SLIC cholecystectomies were successfully completed. Conclusions: SLIC cholecystectomy is feasible and safe. This technique decreases the cumulative incision length, as well as the number of incisions, leading to very desirable cosmetic results in patients with a favorable body habitus and surgical history.

Robotic application to cholecystectomy has dramatically increased, though its impact on cost of care and reimbursement has not been elucidated. We undertook this study to evaluate and compare cost of care and reimbursement with robotic versus laparoscopic cholecystectomy. The charges and reimbursement of all robotic and laparoscopic cholecystectomies at one hospital undertaken from June 2012 to June 2013 were determined. Operative duration is defined as time into and time out of the operating room. Data are presented as median data. Comparisons were undertaken using the Mann-Whitney U-test with significance accepted at p ≤ 0.05. Robotic cholecystectomy took longer (47 min longer) and had greater charges ($8,182.57 greater) than laparoscopic cholecystectomy (p < 0.05 for each). However, revenue, earnings before depreciation, interest, and taxes (EBDIT), and Net Income were not impacted by approach. Relative to laparoscopic cholecystectomy, robotic cholecystectomy takes longer and has greater charges. Revenue, EBDIT, and Net Income are similar after either approach; this indicates that costs with either approach are similar. Notably, this is possible because much of hospital-based costs are determined by cost allocation and not cost accounting. Thus, the cost of longer operations and costs inherent to the robotic approach for cholecystectomy do not translate to a perceived financial burden.

Global Operative Assessment of Laparoscopic Skills (GOALS) assessment has been designed to evaluate skills in laparoscopic surgery. A longitudinal blinded study of randomized video fragments was conducted to estimate the validity and reliability of GOALS in novice trainees. In total, 10 trainees each performed 6 consecutive laparoscopic cholecystectomies. Sixty procedures were recorded on video. Video fragments of (1) opening of the peritoneum; (2) dissection of Calot's triangle and achievement of critical view of safety; and (3) dissection of the gallbladder from the liver bed were blinded, randomized, and rated by 2 consultant surgeons using GOALS. Also, a grade was given for overall competence. The correlation of GOALS with live observation Objective Structured Assessment of Technical Skills (OSATS) scores was calculated. Construct validity was estimated using the Friedman 2-way analysis of variance by ranks and the Wilcoxon signed-rank test. The interrater reliability was calculated using the absolute and consistency agreement 2-way random-effects model intraclass correlation coefficient. A high correlation was found between mean GOALS score (r = 0.879, p = 0.021) and mean OSATS score. The GOALS score increased significantly across the 6 procedures (p = 0.002). The trainees performed significantly better on their sixth when compared with their first cholecystectomy (p = 0.004). The consistency agreement interrater reliability was 0.37 for the mean GOALS score (p = 0.002) and 0.55 for overall competence (p < 0.001) of the 3 video fragments. The validity observed in this randomized blinded longitudinal study supports the existing evidence that GOALS is a valid tool for assessment of novice trainees. A relatively low reliability was found in this study. Copyright © 2014 Association of Program Directors in Surgery. Published by Elsevier Inc. All rights reserved.

Surgeons continually strive to improve technology and patient care. One remarkable demonstration of this is the development of laparoscopic surgery. Once this proved to be a safe and reliable surgical approach, robotics seemed a logical progression of surgical technology. The aim of this project was to evaluate the utility of robotics in the context of single-incision laparoscopic cholecystectomy (SILC). A retrospective review of a prospectively maintained database of robotic single-incision laparoscopic cholecystectomy (RSILC) and traditional SILC performed by a single surgeon at our institution from July 2010 to August 2013 was queried. All consecutive patients undergoing RSILC and SILC during this time period were included. Primary outcomes include conversion rate and operative time. Secondary outcomes include length of stay, duration of narcotic use, time to independent performance of daily activities and cost. Categorical variables were evaluated using Chi-square analysis and continuous variables using t test or Wilcoxon's rank test. Thirty-eight patients underwent RSILC and 44 underwent SILC. BMI was higher in the RSILC group, and the number of patients with prior abdominal surgeries was higher in the SILC group. Otherwise, demographics were similar between the two groups. There was no difference in conversion rate between RSILC and SILC (8 vs 11 %, p = 0.60). Mean operative time for RSILC was significantly greater compared with SILC (98 vs 68 min, p < 0.0001). RSILC was associated with a longer duration of narcotic use (2.3 vs 1.7 days, p = 0.0019) and time to independent performance of daily activities (4 vs 2.3 days, p < 0.0001). Total cost is greater in RSILC ($8961 vs $5379, p < 0.0001). While RSILC can be safely performed, it is associated with longer operative times and greater cost.

Background Association between esophageal achalasia/ gastroesophageal reflux disease (GERD) and cholelithiasis is not clear. Epidemiological data are controversial due to different methodologies applied, the regional differences and the number of patients involved. Results of concomitant cholecistectomy associated to surgical treatment of both diseases regarding safety is poorly understood. Aim To analyze the prevalence of cholelithiasis in patients with esophageal achalasia and gastroesophageal reflux submitted to cardiomyotomy or fundoplication. Also, to evaluate the safety of concomitant cholecistectomy. Methods Retrospective analysis of 1410 patients operated from 2000 to 2013. They were divided into two groups: patients with GERD submitted to laparocopic hiatoplasty plus Nissen fundoplication and patients with esophageal achalasia to laparoscopic cardiomyotomy plus partial fundoplication. It was collected epidemiological data, specific diagnosis and subgroups, the presence or absence of gallstones, surgical procedure, operative and clinical complications and mortality. All groups/subgroups were compared. Results From 1,229 patients with GERD or esophageal achalasia, submitted to laparoscopic cardiomyotomy or fundoplication, 138 (11.43%) had cholelitiasis, occurring more in females (2.38:1) with mean age of 50,27 years old. In 604 patients with GERD, 79 (13,08%) had cholelitiasis. Lower prevalence occurred in Barrett's esophagus patients 7/105 (6.67%) (p=0.037). In 625 with esophageal achalasia, 59 (9.44%) had cholelitiasis, with no difference between chagasic and idiopathic forms (p=0.677). Complications of patients with or without cholecystectomy were similar in fundoplication and cardiomyotomy (p=0.78 and p=1.00).There was no mortality or complications related to cholecystectomy in this series. Conclusions Prevalence of cholelithiasis was higher in patients submitted to fundoplication (GERD). Patients with chagasic or idiopatic forms of achalasia had the

Laparoscopic techniques are commonly used in surgical operations of the gallbladder. There are very few regional anesthesia methods used to achieve this goal. We aimed to investigate the effect of ultrasound-guided posterior quadratus lumborum block (QLB), administered bilaterally on pain scores after laparoscopic cholecystectomy operations. Prospective, double blind, randomized controlled clinical trial. Single-institution, tertiary hospital. 60 patients underwent laparoscopic cholecystectomy were included in the study. Patients were randomized to either Group B (intravenous patient-controlled analgesia (IV PCA) + posterior QLB with 0.3 ml/kg 0.25% bupivacaine; n = 30) or Group S (IV PCA + posterior QLB with 0.3 ml/kg 0,9% saline; n = 30). Postoperative pain (during rest) was evaluated at the 30th minute, 2nd, 6th, 12th, and 24th hours using the VAS scores. Postoperative activity pain was also evaluated with VAS at the 2nd, 6th, 12th, and 24th hours. Postoperative 6th, 12th, and 24th hour follow-up results were recorded to identify the quantity of tramadol use. Secondary outcomes included the Ramsey sedation scale (RSS), side effect profile, and additional analgesic use. The VAS scores between the two groups were found to be statistically significantly lower in Group B (p < 0.001). The mean values of the quantity of tramadol use at the 6th, 12th, and 24th hours were found to be statistically significantly lower in Group B (p < 0.001). There was no statistically significant difference in the rate of side effects (p = 0.309) and RSS (p = 0.505) outcomes between the groups. As a result of this study, we think that posterior QLB administered for pain palliation after laparoscopic cholecystectomy operation is an effective analgesia technique.

Introduction Pain control after a laparoscopic cholecystectomy can represent a challenge, considering the side effects due to standard analgesia methods. Recently the transversus abdominis plane block (TAP Block) has been used as a part of multimodal analgesia with promising results. The subcostal approach (OSTAP Block), a variant on the TAP block, produces reliable unilateral supraumbilical analgesia. This study evaluated the efficacy of the OSTAP block with bupivacaine in laparoscopic cholecystectomy compared with the placebo OSTAP block. Material and Methods Sixty ASA I/II adult patients listed for elective laparoscopic cholecystectomy were randomly allocated in one of two groups: Group A (OSTAP placebo) received preoperatively bilateral OSTAP block with sterile normal saline and Group B (OSTAP bupivacaine) received bilateral preoperatively OSTAP block with the same volumes of 0.25% bupivacaine. Twenty-four hours postoperative opioid consumption, the dose of opioid required during surgery, opioid dose in the recovery unit (PACU) and PACU length of stay were evaluated. The quality of analgesia was assessed by the Visual Analogue Scale (VAS) at specific interval hours during 24 h, at rest and with movement. Results The mean intraoperative opioid consumption showed a significant difference between the two groups, (385 ± 72.52 mg in group A vs 173.67 ± 48.60 mg in group B, p < 0.001). The mean 24 h opioid consumption showed a statistically significant difference between groups (32 ± 26.05 mg vs 79 ± 16.68 mg, p < 0.001). PACU length of stay was significantly lower for group B patients compared with group A patients (20.67 ± 11.27 min vs 41.67 ± 12.41 min, p < 0.001). The OSTAP bupivacaine group had a statistically significant lower pain score than the OSTAP placebo group at 0, 2, 4, 6, 12, 24 h, both at rest and with movement. No signs or symptoms of local anaesthetic systemic toxicity or other complications were detected. Conclusion OSTAP block with

Background The value of robotics in general surgery may be for advanced minimally invasive procedures. Unlike other specialties, formal fellowship training opportunities for robotic general surgery are few. As a result, most surgeons currently develop robotic skills in practice. Our goal was to determine whether robotic cholecystectomy is a safe and effective bridge to advanced robotics in general surgery. Methods Before performing advanced robotic procedures, 2 surgeons completed the Intuitive Surgical da Vinci training course and agreed to work together on all procedures. Clinical surgery began with da Vinci cholecystectomy with a plan to begin advanced procedures after at least 10 cholecystectomies. We performed a retrospective review of our pilot series of robotic cholecystectomies and compared them with contemporaneous laparoscopic controls. The primary outcome was safety, and the secondary outcome was learning curve. Results There were 16 procedures in the robotics arm and 20 in the laparoscopic arm. Two complications (da Vinci port-site hernia, transient elevation of liver enzymes) occurred in the robotic arm, whereas only 1 laparoscopic patient (slow to awaken from anesthetic) experienced a complication. None was significant. The mean time required to perform robotic cholecystectomy was significantly longer than laparoscopic surgery (91 v. 41 min, p < 0.001). The mean time to clear the operating room was significantly longer for robotic procedures (14 v. 11 min, p = 0.015). We observed a trend showing longer mean anesthesia time for robotic procedures (23 v. 15 min). Regarding learning curve, the mean operative time needed for the first 3 robotic procedures was longer than for the last 3 (101 v. 80 min); however, this difference was not significant. Since this experience, the team has confidently gone on to perform robotic biliary, pancreatic, gastresophageal, intestinal and colorectal operations. Conclusion Robotic cholecystectomy can be performed reliably

Objective To evaluate the effects of an ultrasound-guided transverse abdominis plane (US-TAP) block used for postoperative pain relief by comparing the efficacy of two different volumes/concentrations of the local anaesthetic bupivacaine in patients undergoing laparoscopic cholecystectomies. Methods This randomized study enrolled patients undergoing laparoscopic cholecystectomies. They were randomized to two groups: group A received a 20 ml US-TAP block (50 mg bupivacaine +10 ml saline solution) and group B received a 30 ml US-TAP block (50 mg bupivacaine + 20 ml saline solution). The intraoperative consumption of remifentanil, the requirement for postoperative rescue analgesics, patient satisfaction scores, postoperative complications, and postoperative pain as measured by a visual analogue scale at 20 min, 12 h, and 24 h were recorded. Results A total of 60 patients enrolled in the study. There were no differences between the two groups with respect to demographic characteristics, duration of anaesthesia and patient satisfaction scores. The intraoperative consumption of remifentanil, postoperative VAS scores (20 min, 12 h and 24 h) and the requirement for postoperative analgesics were all significantly lower in group B who received a larger volume but a lower concentration of local anaesthetic solution compared with group A. Conclusion A US-TAP block can form part of a balanced postoperative analgesic regimen following laparoscopic cholecystectomy.

The ideal method for managing concomitant gallbladder stones and common bile duct (CBD) stones is debatable. The currently preferred method is two-stage endoscopic stone extraction followed by laparoscopic cholecystectomy (LC). This prospective randomized trial compared the success and cost effectiveness of single- and two-stage management of patients with concomitant gallbladder and CBD stones. Consecutive patients with concomitant gallbladder and CBD stones were randomized to either single-stage laparoscopic CBD exploration and cholecystectomy (group 1) or endoscopic retrograde cholangiopancreatography (ERCP) for endoscopic extraction of CBD stones followed by LC (group 2). Success was defined as complete clearance of CBD and cholecystectomy by the intended method. Cost effectiveness was measured using the incremental cost-effectiveness ratio. Intention-to-treat analysis was performed to compare outcomes. From February 2009 to October 2012, 168 patients were randomized: 84 to the single-stage procedure (group 1) and 84 to the two-stage procedure (group 2). Both groups were matched with regard to demographic and clinical parameters. The success rates of laparoscopic CBD exploration and ERCP for clearance of CBD were similar (91.7 vs. 88.1 %). The overall success rate also was comparable: 88.1 % in group 1 and 79.8 % in group 2 (p = 0.20). Direct choledochotomy was performed in 83 of the 84 patients. The mean operative time was significantly longer in group 1 (135.7 ± 36.6 vs. 72.4 ± 27.6 min; p ≤ 0.001), but the overall hospital stay was significantly shorter (4.6 ± 2.4 vs. 5.3 ± 6.2 days; p = 0.03). Group 2 had a significantly greater number of procedures per patient (p < 0.001) and a higher cost (p = 0.002). The two groups did not differ significantly in terms of postoperative wound infection rates or major complications. Single- and two-stage management for uncomplicated concomitant gallbladder and CBD stones had similar success and complication rates

The size of laparoscopic instruments has been reduced for use in abdominal video endoscopic surgery. However, it has yet to be proven that microlaparoscopic surgery will actually result in clinically relevant benefits for patients. Fifty patients were randomized in a blinded fashion to receive either elective laparoscopic (MINI), (n = 25) or microlaparoscopic (MICRO) (n = 25) cholecystectomy. Pulmonary function (FVC, FEV (1)), analgesic consumption during patient-controlled analgesia (PCA), pain perception by visual analogue score (VAS), and the cosmetic result (by the patient's self-assessment) were evaluated postoperatively as clinically relevant end points. Age, sex, body mass index (BMI), preoperative pulmonary function, pain perception, and operative time were similar for the two groups. At 8:00 PM on the day of surgery, FVC (MINI: 1.96 L [range, 1.48-2.48]; MICRO: 2.13 L) [(range, 1.61.-2.50)] and FEV (1) (MINI: 1.17 L/sec) [range, 0.87-1. 48]; MICRO: 1.34 L/sec [range, 1.05.-2.14] were also similar (each p = 0.5). From surgery to the 3rd postoperative day, cumulative PCA morphine doses were comparable (MINI: 0.15 mg/kg bw [range, 0.09-0. 23]; MICRO: 0.21 mg/kg bw [range, 0.10-0.42]; p = 0.4), but overall VAS scores for pain while coughing were higher in the laparoscopic group (406 [range, 358-514]) than in the microlaparoscopic group (365 [range, 215-427]; p = 0.02). The cosmetic result was judged to be slightly superior by the microlaparoscopic patients (10 [range, 9-10]), as compared to those in the laparoscopic (9 [range, 8-10]) group (p = 0.04). Because microlaparoscopic cholecystectomy has some minor advantages over laparoscopic surgery, it should be considered for use in selected patients.

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.

Pre-operative endosonography has been proposed as a cost-effective procedure in the management of patients who undergo laparoscopic cholecystectomy having an intermediate risk of common bile duct stones. We prospectively evaluated the impact of pre-operative endosonography on the management of patients facing laparoscopic cholecystectomy with abnormal liver function tests as the sole risk factor for choledocolithiasis. Among 587 consecutive patients scheduled for laparoscopic cholecystectomy, 47 (8%) patients having one or more abnormal liver function tests but a normal appearance of common bile duct at abdominal ultrasound, underwent pre-operative endosonography. In patients with endosonography-detected common bile duct stones, a pre-operative endoscopic retrograde cholangiography was performed, or an intra-operative endoscopic retrograde cholangiography was scheduled. In all endosonography-negative patients, an intra-operative trans-cystic cholangiography was performed. Endosonography detected common bile duct stones in nine patients (19%) but only in five of them stones were radiologically confirmed (PPV 0.55). Endosonography-detected stones were confirmed in four of four (100%) patients in whom cholangiography was performed within 1 week, but only in one of five (20%) patients in whom radiology was further delayed (P < 0.05). In three of four cases (75%), stones detected at endosonography but not confirmed at X-rays, were smaller than 2.0 mm. Among 38 patients with negative endosonography, common bile duct stones were found in two patients (NPV 0.95), whereas unplanned endoscopic stone extraction was needed only in one patient (NPV 0.97). Pre-operative endosonography can spare unnecessary pre-operative endoscopic retrograde cholangiography as well as inappropriate scheduling of intra-operative endoscopic retrograde cholangiography in patients undergoing laparoscopic cholecystectomy with abnormal liver function tests. To maximise the impact of endosonography on

Routine administration of antibiotics to patients suffering accidental gallbladder perforation during laparoscopic cholecystectomy is not necessary.

Accidental rupture of the gallbladder is an event which occurs in up to 20% of laparoscopic cholecystectomies, mainly in those where dissection is difficult, or during extraction when the gallbladder is withdrawn directly through the laparoscope port. It has been commonly assumed that contamination by bile in the abdominal cavity could be a cause of infection and lead to the formation of a residual abscess or even to surgical wound infection. It is common practice, therefore, for the surgeon to prescribe the application of an antibiotic at the moment when gallbladder perforation occurs. To compare 2 groups of similar patients, to determine whether administration of antibiotics, started during surgery, is actually useful in reducing the risk of residual abscess or infection in the surgical wound. The study considered a total of 166 patients who had suffered accidental perforation of the gallbladder during elective laparoscopic cholecystectomy. This total was divided at random into 2 groups: group A (80 patients) who received a dose of 1 g of Cefotaxime at the moment of gallbladder rupture, followed by 2 more doses at intervals of 8 hours in the immediate postoperative period; and group B (86 patients) who did not receive any antibiotic treatment at all. The dependent variables observed were surgical wound infection and residual abscess: and the control variables were age, sex, length of operation time, intercurrent illnesses, and American Society of Anesthesiologists (ASA) classification. Two patients (2.5%) in group A developed a surgical wound infection, against 3 cases (3.4%) in group B, the result having no statistical significance. No patients developed residual abscess. In a multivariant analysis, the following were identified as independent factors significantly associated with the onset of surgical wound infection (P<0.001): diabetes mellitus, being over 60 years of age, operation time lasting longer than 70 minutes, and ASA 3.

Ultrasonic dissection has been suggested as an alternative to monopolar electrocautery in laparoscopic cholecystectomy because it generates less tissue damage and may have a lower incidence of gallbladder perforation. We compared the 2 methods to determine the incidence of gallbladder perforation and its intraoperative consequences. We conducted a prospective randomized controlled trial between July 2008 and December 2009 involving adult patients with symptomatic gall stone disease who were eligible for laparoscopic cholecystectomy. Patients were randomly assigned before administration of anesthesia to electrocautery or ultrasonic dissection. Both groups were compared for incidence of gallbladder perforation during dissection, bile leak, stones spillage, lens cleaning, duration of surgery and estimation of risk of gallbladder in the presence of complicating factors. We included 60 adult patients in our study. The groups were comparable with respect to demographic characteristics, symptomatology, comorbidities, previous abdominal surgeries, preoperative ultrasonography findings and intraoperative complications. The overall incidence of gallbladder perforation was 28.3% (40.0% in the electrocautery v. 16.7% in the ultrasonic dissection group, p = 0.045). Bile leak occurred in 40.0% of patients in the electrocautery group and 16.7% of patients in ultrasonic group (p = 0.045). Lens cleaning time (p = 0.015) and duration of surgery (p = 0.001) were longer in the electrocautery than the ultrasonic dissection group. There was no statistical difference in stone spillage between the groups (p = 0.62). Ultrasonic dissection is safe and effective, and it improves the operative course of laparoscopic cholecystectomy by reducing the incidence of gallbladder perforation.

Although single-incision laparoscopic cholecystectomy is now widely performed in patients with cholecystitis, some cases require an additional port to complete the procedure. In this study, we focused on risk factor of additional port in this surgery. We performed single-incision cholecystectomy in 75 patients with acute cholecystitis or after cholecystitis between 2010 and 2014 at Gunma University Hospital. Surgical indications followed the TG13 guidelines. Our standard procedure for single-incision cholecystectomy routinely uses two needlescopic devices. We used logistic regression analysis to identify the risk factors associated with use of an additional full-size port (5 or 10 mm). Surgical outcome was acceptable without biliary injury. Nine patients (12.0%) required an additional port, and one patient (1.3%) required conversion to open cholecystectomy because of severe adhesions around the cystic duct and common bile duct. In multivariate analysis, high C-reactive protein (CRP) values (>7.0 mg/dl) during cholecystitis attacks were significantly correlated with the need for an additional port (P = 0.009), with a sensitivity of 55.6%, specificity of 98.5%, and accuracy of 93.3%. This study indicated that the severe inflammation indicated by high CRP values during cholecystitis attacks predicts the need for an additional port. J. Med. Invest. 64: 245-249, August, 2017.

An higher incidence rate of iatrogenic bile duct injuries is reported in cholecystectomy performed with the laparoscopy than with the laparotomy approach. The aim of this study was to provide a multicentre report on surgical treatment and the outcome of biliary complications during and following laparoscopic cholecystectomy. A questionnaire was mailed to all surgeons with experience in laparoscopic cholecystectomy in the Campania region. Data were collected from January 1991 to December 2003. Each patient was requested to indicate age, gender, associated diseases, site and type of lesion, surgical experience, diagnosis, treatment and complications. Twenty-six surgeons answered the questionnaire. Fifty-one patients (36 F/15 M; mean age: 42.5 +/- 11.9, range 13-91 years) with bile duct injuries following laparoscopic cholecystectomy were reported. The most frequent lesions were main bile duct partial or total transection. The intraoperative mortality rate was 1/51 (1.9%) due to a complex biliary and vascular injury. The postoperative mortality rate of revision surgery was 5/50 (10%). T-tube positioning (n = 20) and Roux-en-Y hepato-jejunostomy (n = 20) were the procedures most frequently performed. The complication rate in patients treated with the T-tube was significantly higher than in those treated with hepatico-jejunostomy. Surgical treatment of biliary injuries following laparoscopic cholecystectomy was characterized by unusually high mortality and morbidity for a non-neoplastic disease. Roux-en-Y hepato-jejunostomy remains the procedure of choice for these injuries.

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. 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. 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. 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.

With the recent advances in eye tracking technology, it is now possible to track surgeons’ eye movements while engaged in a surgical task or when surgical residents practice their surgical skills. Several studies have compared eye movements of surgical experts and novices and developed techniques to assess surgical skill on the basis of eye movement utilizing simulators and live surgery. None have evaluated simultaneous visual tracking between an expert and a novice during live surgery. Here, we describe a successful simultaneous deployment of visual tracking of an expert and a novice during live laparoscopic cholecystectomy. One expert surgeon and one chief surgical resident at an accredited surgical program in Lubbock, TX, USA performed a live laparoscopic cholecystectomy while simultaneously wearing the visual tracking devices. Their visual attitudes and movements were monitored via video recordings. The recordings were then analyzed for correlation between the expert and the novice. The visual attitudes and movements correlated approximately 85% between an expert surgeon and a chief surgical resident. The surgery was carried out uneventfully, and the data was abstracted with ease. We conclude that simultaneous deployment of visual tracking during live laparoscopic surgery is a possibility. More studies and subjects are needed to verify the success of our results and obtain data analysis. PMID:27774359

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 cholecystectomy is the gold standard treatment for gallbladder stones. Complications due to laparoscopic procedure are rare, but rate of wound infection in some studies is about 8 %. From January 2007 to December 2008, 320 laparoscopic cholecystectomies were performed at our hospital, and in 4.7 % of them, wound infection of the umbilical trocar was identified. We believe that this infection rate could be lower and that it is necessary to implement a new technique to reduce the wound infection. The aim of the study was to evaluate the benefits of bag extraction of gallbladder to prevent the wound infection. Two-arm, parallel, 1:1, randomised controlled trial (ISRCTN38095251). All patients suffering from symptomatic gallbladder stones of low risk were enrolled for this study and were divided into two groups in basics gallbladder extraction: with (80 patients) or, as usually, without bag (76 patients). All patients with cholecystitis or accidental gallbladder perforation were excluded. We compared all the results to establish whether meaningful differences were found. The final sample analysed (156 patients) consisted of 121 women and 35 men; there were 80 in the control group and 76 in the study group. There were 15 (9.6 %) diagnosed wound infections, eight cases in the study group and seven in the control group. There were no statistically significant differences. The determinant of wound infection in elective laparoscopic cholecystectomy is not the direct contact of the gallbladder with the wound; therefore, bag extraction is not necessary.

With the advent and rapid proliferation of laparoscopic cholecystectomy, numerous techniques and "tips" have been described. Intraoperative cholangiography during laparoscopic cholecystectomy can be tedious, frustrating, and time consuming. Described herein is a technique of intraoperative cholangiography during laparoscopic cholecystectomy which has proven to be easy, fast, and succinct. This method utilizes a rigid cholangiogram catheter which is placed into the peritoneal cavity through a small additional puncture site. This catheter is easily inserted into the cystic duct by extracorporeal manipulation. We suggest this method to surgeons who have shared our prior frustration with intraoperative cholangiography.

The influence of laparoscopic cholecystectomy (LC) on the mechanical properties of the respiratory system (RS) was examined using multiple regression analysis (MRA). Measurements of airway pressure (PaO) and flow (V') were obtained from 32 patients at four distinct stages of the LC procedure: 1) Immediately before the application of pneumoperitoneum (PP) at supine position, 2) 5 min after the induction of PP at Trendelenburg position, 3) 5 min after the patients position at reverse Trendelenburg, and 4) 5 min after the end ofthe surgical procedure with the patient again in supine position. Evaluated parameters were the RS elastance (Ers), resistance (Rrs), impedance (Zrs), the angle theta indicating the balance between the elastic and resistive components of the impedance, as well as the end-expiratory elastic recoil pressure (EEP). Ers and Zrs increased considerably during PP and remained elevated immediately after abolishing PP Rrs, on the contrary, returned to pre-operative levels right after the operation. Change of body position from Trendelenburg (T) to reverseTrendelenburg (rT) mainly induced a significant change in theta, thus indicating an increased dominance of the elastic component of Zrs on changing fromT to rT. There was no evidence of increased End-Expiratory Pressure during PP

Gallstones have led to pain and complications in humankind for millennia. Beginning in the 1880s, cholecystectomy, performed through a sizable abdominal incision, was the treatment of choice for symptomatic cholelithiasis. During the late 1980s pioneering surgeons first used laparoscopic techniques to remove the gallbladder. Although initially associated with a significantly increased rate of bile duct injury, the clinical advantages of laparoscopy compared to open operation became readily apparent, ushering in the "laparoscopic revolution." More recently, attempts at rendering cholecystectomy even less invasive--smaller or fewer incisions or eliminating abdominal incisions altogether--have been described, with limited clinical series reported. At the current time, laparoscopic cholecystectomy is the gold standard for gallbladder removal, and any newer techniques must be demonstrated to result in superior outcomes for widespread adoption.

2017-01-01

Aim To evaluate the technical feasibility and oncologic safety of laparoscopic radical cholecystectomy (LRC) for primary or incidental early gallbladder cancer (GBC) treatment. Methods Articles reporting LRC for GBC were reviewed from the first case reported in 2010 to 2015 (129 patients). 116 patients had a preoperative diagnosis of gallbladder cancer (primary GBC). 13 patients were incidental cases (IGBC) discovered during or after a laparoscopic cholecystectomy. Results The majority of patients who underwent LRC were pT2 (62.7% GBC and 63.6% IGBC). Parenchyma-sparing operation with wedge resection of the gallbladder bed or resection of segments IVb-V were performed principally. Laparoscopic lymphadenectomy was carried out according to the reported depth of neoplasm invasion. Lymph node retrieved ranged from 3 to 21. Some authors performed routine sampling biopsy of the inter-aorto-caval lymph nodes (16b1 station) before the radical treatment. No postoperative mortality was documented. Discharge mean day was POD 5th. 16 patients had post operative morbidities. Bile leakage was the most frequent post-operative complication. 5 y-survival rate ranged from 68.75 to 90.7 months. Conclusion Laparoscopy can not be considered as a dogmatic contraindication to GBC but a primary approach for early case (pT1b and pT2) treatment. PMID:28690639

In this multicenter, double-blinded, randomized, placebo-controlled study we evaluated the analgesic and opioid-sparing efficacy of a preoperative dose of i.v. parecoxib followed by oral valdecoxib in treating pain associated with elective laparoscopic cholecystectomy. Patients were randomized to receive a single i.v. dose of parecoxib 40 mg (n = 134) or placebo (n = 129) 30-45 min before induction of anesthesia. Six to 12 h after the i.v. dose, the parecoxib group received a single oral dose of valdecoxib 40 mg, followed by valdecoxib 40 mg qd on postoperative days 1-4, then 40 mg qd prn days 5-7. The placebo i.v. group received oral placebo on an identical schedule. All patients were allowed supplemental i.v. fentanyl as needed during the first 4 h postoperatively (T0-240 min) followed by hydrocodone 5 mg/acetaminophen 500 mg (Vicodin(R); 1-2 tablets orally every 4-6 h as needed). Patients taking parecoxib used 21% less fentanyl than those receiving placebo (P = 0.011). The mean area under the curve of pain intensity (PI) scores over time from T0-240 min was 55.2 for parecoxib and 61.2 for placebo (P = 0.083). At T180 and T240 min, mean PI score was 7.0 and 7.6 points lower in the parecoxib group, respectively (P < 0.02). Fewer patients on valdecoxib required supplemental analgesics (P < 0.05) after discharge. At T240 min and at day 7, Patient's and Physician's/Nurse's Global Evaluations were significantly better in the parecoxib/valdecoxib group (P < 0.05). Incidences of adverse events, adverse events causing withdrawal, and serious adverse events were less for parecoxib/valdecoxib than for placebo. The authors conclude that preoperative parecoxib is a valuable opioid-sparing adjunct to the standard of care for treating pain after laparoscopic cholecystectomy, and subsequent treatment with oral valdecoxib extends this clinical benefit. Parecoxib 40 mg i.v., 30-45 min preoperatively followed by oral valdecoxib 40 mg qd reduced opioid requirements and provided

Aims: In our group, after a study showing that spinal anesthesia is safe when compared with general anesthesia, spinal anesthesia has been the technique of choice for this procedure. This is a prospective study with all patients undergoing LC under spinal anesthesia in our department since 2007. Settings and Design: Prospective observational. Materials and Methods: From 2007 to 2011, 369 patients with symptoms of colelithiasis, laparoscopic cholecystectomy were operated under spinal anesthesia with pneumoperitoneum and low pressure CO2. We compared 15 mg of hyperbaric bupivacaine and lumbar puncture with 10 or 7.5 mg of hyperbaric bupivacaine thoracic puncture, all with 25 μg fentanyl until the sensory level reached T3. Intraoperative parameters, post-operative pain, complications, recovery, patient satisfaction, and cost were compared between both groups. Statistical Analysis Used: Means were compared by ANOVA or Kruskal-Wallis test, the percentages of the Chi-square test or Fisher's exact test when appropriate. Time of motor and sensory block in spinal anesthesia group was compared by paired t test or Mann-Whitney test. Differences were considered significant when P ≤ 0.05, and for comparisons of mean pain visual scale, we employed the Bonferroni correction applied to be considered significant only with P ≤ 0.0125 Results: All procedures were completed under spinal anesthesia. The use of lidocaine 1% was successful in the prevention of shoulder pain in 329 (89%) patients. There were significant differences in time to reach T3, obtaining 15 mg > 10 mg = 7.5 mg. There is a positive correlation between the dose and the incidence of hypotension. The lowest doses gave a decrease of 52.2% in the incidence of hypotension. There was a positive correlation between the dose and duration of sensory and motor block. Sensory block was almost twice the motor block at all doses. With low doses, 60% of patients went from table to stretcher. Satisfaction occurred in 99% of

The length of incisions on the abdominal wall directly correlates with wound-related morbidities and patient comfort. Both mini-laparoscopy (only ≤5-mm trocars) and natural orifice specimen extraction avoid larger abdominal incisions. This study described a new natural orifice translumenal endoscopic surgery (NOTES(®); American Society for Gastrointestinal Endoscopy [Oak Brook, IL] and Society of American Gastrointestinal and Endoscopic Surgeons [Los Angeles, CA]) cholecystectomy technique by combination of these two advanced laparoscopic techniques for cholelithiasis in patients who had prior laparoscopic Roux-en-Y gastric bypass (LRYGB) for obesity. Three patients (two males, one female; 39, 62, and 34 years old, respectively) were admitted with symptomatic cholelithiasis (multiple millimeter-sized gallstones), and all had previously had LRYGB. They were treated by mini-laparoscopic cholecystectomy using three 5-mm trocars. The gallbladder was removed through the dilated efferent limb of the jejunum, 5 cm distal from the gastrojejunostomy. Transjejunal extraction was performed under endoscopic guidance. The gallbladder in the jejenum was passed through the anastomosis and extracted with an endoscopic snare by the transoral way. The enterotomy was closed intracorporeally. There was no conversion or additional trocar requirement. All the procedures were completed successfully without problems. Respective operating times were 95, 75, and 120 minutes. Only 1 patient required postoperative analgesic; the others did not. The patients started to get a liquid diet on the night of surgery and were discharged on Days 1, 1, and 2, respectively, with normal diet recommendations. There were no morbidities. Mini-laparoscopic cholecystectomy is technically feasible in patients with previous LRYGB. Prior LRYGB was not an obstacle for transoral specimen extraction. The dilated efferent jejunal limb is a good alternative route for natural orifice specimen extraction. This

The laparoscopic approach to cholecystectomy has overtaken open procedures in terms of frequency, despite open procedures playing an important role in certain clinical situations. This study explored exposure and confidence of Australasian surgical trainees and new fellows in performing an open versus laparoscopic cholecystectomy. An online survey was disseminated via the Royal Australasian College of Surgeons to senior general surgery trainees (years 3-5 of surgical training) and new fellows (fellowship within the previous 5 years). The survey included questions regarding level of experience and confidence in performing an open cholecystectomy and converting from a laparoscopic to an open approach. A total of 135 participants responded; 58 (43%) were surgical trainees, 58 (43%) were fellows and 19 (14%) did not specify their level of training. Respondents who were involved in more than 20 open cholecystectomy procedures as an assistant or independent operator compared with those less exposed were more likely to feel confident to independently perform an elective open cholecystectomy (87.8% vs. 57.3%, P = 0.001), independently convert from a laparoscopic to open cholecystectomy (87.8% vs. 58.7%, P = 0.001) and independently perform an open cholecystectomy as a surgical consultant based on their level of exposure as a trainee (73.2% vs. 45.3%, P = 0.004). This study suggests the need to ensure surgical trainees are exposed to sufficient open cholecystectomies to enable confidence and skill with performing these procedures when indicated. Greater recognition of the need for exposure during training, including meaningful simulation, may assist. Crown Copyright © 2018. Published by Elsevier Ltd. All rights reserved.

Laparoscopic cholecystectomy is considered to be the gold standard surgical procedure for cholelithiasis and is one of the commonest surgical procedures in the world today. However, in rare cases of previously undiagnosed situs inversus totalis (with dextrocardia), the presentation of the cholecystitis, its diagnosis and the operative procedure can pose problems. We present here one such case and discuss how the diagnosis was made and difficulties encountered during surgery and how they were coped with. A 35 year old female presented with left hypochondrium pain and dyspepsia, for 2 years. A diagnosis of cholelithiasis with situs inversus was confirmed after thorough clinical examination, abdominal and chest X-rays and ultrasonography of the abdomen. Laparoscopic cholecystectomy, which is the standard treatment, was performed with numerous modifications in the positioning of the monitor, insufflator, ports and the position of the members of the surgical team and the laparoscopic instruments. The patient had an uneventful recovery. Situs inversus totalis is itself a rare condition and when associated with cholelithiasis poses a challenge in the management of the condition. We must appreciate the necessity of setting up the operating theatre, the positioning of the ports, the surgical team and the instruments. Therefore, it becomes important for the right handed surgeons to modify their techniques and establish a proper hand eye coordination to adapt to the mirror image anatomy of the Calot's triangle in a patient of situs inversus totalis.

Purpose Laparoscopic cholecystectomy (LC) is usually performed under the general anesthesia (GA). Aim of the study is to investigate the availability, safety and side effects of combined spinal/epidural anesthesia (CSEA) and comparison it with GA for LC. Methods Forty-nine patients who have a LC plan were included into the study. The patients were randomly divided into GA (n = 25) and CSEA (n = 24) groups. Intraoperative and postoperative adverse events, postoperative pain levels were compared between groups. Results Anesthesia procedures and surgeries for all patients were successfully completed. After the organization of pneumoperitoneum in CSEA group, 3 patients suffered from shoulder pain (12.5%) and 4 patients suffered from abdominal discomfort (16.6%). All these complaints were recovered with IV fentanyl administration. Only 1 patient developed hypotension which is recovered with fluid replacement and no need to use vasopressor treatment. Postoperative shoulder pain was significantly less observed in CSEA group (25% vs. 60%). Incidence of postoperative nausea and vomiting (PONV) was less observed in CSEA group but not statistically significant (4.2% vs. 20%). In the group of CSEA, 3 patients suffered from urinary retention (12.5%) and 2 patients suffered from spinal headache (8.3%). All postoperative pain parameters except 6th hour, were less observed in CSEA group, less VAS scores and less need to analgesic treatment in CSEA group comparing with GA group. Conclusion CSEA can be used safely for laparoscopic cholecystectomies. Less postoperative surgical field pain, shoulder pain and PONV are the advantages of CSEA compared to GA. PMID:28289667

The use of endoscopic retrograde cholangiopancreatography (ERCP) in the management of suspected common bile duct (CBD) stones prior to laparoscopic cholecystectomy is common. The associated morbidity can be significant. The present study determines significant predictors of CBD stones and improves the selection of patients for preoperative ERCP. All preoperative ERCP for suspected CBD stones in the year 1998 were studied retrospectively. Univariate and multivariate analyses of a number of clinical, biochemical and radiological variables were carried out to determine the best predictors of CBD stones. A total of 112 patients had successful preoperative ERCP. Sixty-one per cent of these were negative for stones and the morbidity was 9%. Univariate analysis revealed the following variables as predictors: cholangitis (P = 0.006), abnormal serum bilirubin > or = 3 days (P = 0.002), serum alkaline phosphatase > or = 130 U/L (P = 0.002), deranged liver function tests (P = < 0.001) and CBD diameter > or = 8 mm (P = 0.009) with positive predictive values of 80%, 68%, 49%, 38% and 52%, respectively. Multivariate analysis revealed the model with the best ability to discriminate for CBD stones (P = 0.0005) was cholangitis, abnormal serum bilirubin for > or = 3 days and CBD diameter > or = 8 mm. The best predictors from this study had a sensitivity of 80% and a specificity of 27%. The predictors of CBD stones are imprecise. Until laparoscopic exploration of CBD becomes widely available, ERCP prior to cholecystectomy will remain popular. The use of stricter selection criteria can reduce the number of negative preoperative ERCP.

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.

Background The minimally invasive abdominal surgery has evolved to reduce portals, culminating with a single incision and natural orifice operation. However, these methods are still expensive, difficult to implement and with questionable aesthetic results. Aim To present the standardization and preliminary results of a technique for performing laparoscopic suprapubic access by the principle which was called the Supra Pubic Endoscopic Surgery for cholecystectomy. Method The average body mass index of patients, the mean operative time, clinical data of the postoperative complications and quality of life were prospectively studied. The operation incisions consisted of: A) umbilical for instrumental dissection and clipping; B) in the right groin for handling and gallbladder gripping; C) suprapubic for the camera. With the patient in reverse Trendelenburg and left lateral decubitus, the operation flew by the camera trocar in C, proceeding with dissection and isolation of the biliary pedicle, identification of cystic duct and artery, with usual instrumentation. Transcystic intraoperative cholangiography was performed in all cases in which there were indications. The procedure was completed with clipping and sectioning of the cystic duct and artery, retrograde resection of the gallbladder and extracting it by the umbilical trocar incision under direct vision. Results Thirty patients undergone this surgical procedure between March and June 2012 and were evaluated. The mean age was 40.7 years and the indications were typical biliary colic in 18 cases (60 %), cholecystitis in five cases (16.6 %), biliary pancreatitis in one case (3.3%); polyp in three cases (10%) and obstructive jaundice at three cases (10%). The average body mass index was 27.8 (23.1-35.1) and surgical time ranged between 24 and 70 minutes. Conclusion The technique proved to be feasible and safe , with no significant complications, and satisfactory cosmetic results. PMID:24676293

Abstract This study compared virtual reality (VR) training with low cost-blended learning (BL) in a structured training program. Training of laparoscopic skills outside the operating room is mandatory to reduce operative times and risks. Laparoscopy-naïve medical students were randomized in 2 groups stratified for sex. The BL group (n = 42) used E-learning for laparoscopic cholecystectomy (LC) and practiced basic skills with box trainers. The VR group (n = 42) trained basic skills and LC on the LAP Mentor II (Simbionix, Cleveland, OH). Each group trained 3 × 4 hours followed by a knowledge test concerning LC. Blinded raters assessed the operative performance of cadaveric porcine LC using the Objective Structured Assessment of Technical Skills (OSATS). The LC was discontinued when it was not completed within 80 min. Students evaluated their training modality with questionnaires. The VR group completed the LC significantly faster and more often within 80 min than BL (45% v 21%, P = .02). The BL group scored higher than the VR group in the knowledge test (13.3 ± 1.3 vs 11.0 ± 1.7, P < 0.001). Both groups showed equal operative performance of LC in the OSATS score (49.4 ± 10.5 vs 49.7 ± 12.0, P = 0.90). Students generally liked training and felt well prepared for assisting in laparoscopic surgery. The efficiency of the training was judged higher by the VR group than by the BL group. VR and BL can both be applied for training the basics of LC. Multimodality training programs should be developed that combine the advantages of both approaches. PMID:25997044

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.

Pethidine is a synthetic opioid with local anesthetic properties. Our goal was to evaluate the analgesic efficacy of pethidine for achieving the ultrasound-guided oblique subcostal transversus abdominis plane (OSTAP) block in laparoscopic cholecystectomy. This prospective, double-blind study included 79 patients of physical status I and II according to American Society of Anesthesiologists, scheduled for elective laparoscopic cholecystectomy. The patients were randomly allocated into three groups, depending on the drug used to achieve preoperative bilateral OSTAP block: 1) OSTAP-Placebo (treated with normal saline); 2) OSTAP-Bupivacaine (treated with 0.25% bupivacaine); and 3) OSTAP-Pethidine (treated with 1% pethidine). The efficacy of pethidine in achieving the OSTAP block was analyzed using visual analog scale (VAS), intraoperative opioid dose, opioid consumption in post anesthesia care unit, and opioid consumption in the first 24 postoperative hours. The pain scores assessed by VAS at 0, 2, 4, 6, 12, and 24 hours were significantly lower in OSTAP-Pethidine than in OSTAP-Placebo group (p < 0.001). The mean intraoperative opioid consumption was significantly lower in OSTAP-Pethidine compared to OSTAP-Placebo group (150 versus 400 mg, p < 0.001), as well as the mean opioid consumption in the first 24 hours (20.4 versus 78 mg, p < 0.001). Comparing VAS assessment between OSTAP-Bupivacaine and OSTAP-Pethidine groups, statistically significant differences were observed only for the immediate postoperative pain assessment (0 hours), where lower values were observed in OSTAP-Pethidine group (p = 0.004). There were no statistically significant differences in the incidence of postoperative nausea and vomiting (p = 0.131) between the groups. The use of 1% pethidine can be an alternative to 0.25% bupivacaine in achieving OSTAP block for laparoscopic cholecystectomy.

Twelve patients with iatrogenic bile duct injuries occurred during laparoscopic cholecystectomy (LC) were treated from June 1992 to May 1994. All the patients underwent re-operation and were cured. The causes and characteristics of the injuries were: (1) perforation of the common hepatic or common bile duct caused by dissecting hook (3 cases); (2) necrosis and perforation of the common hepatic duct due to diathermic injury (1 case); (3) clamping of the common hepatic duct by Ti clip (1 case); (4) secondary high bile duct stricture following a failed end-to-end anastomosis or hepatico-cholangio-jejunostomy of the amputated common hepatic duct (5 cases); (5) delayed high bile duct stricture (2 cases). It is emphasized that the severity of bile duct injuries by LC be should not overlooked, and more experience in this field be accumulated to avoid this serious complication.

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.

True left-sided gallbladder (LSG) is a rare finding that may present with symptoms similar to those of a normally positioned gallbladder. Moreover, it may be missed by preoperative imaging studies such as ultrasound, computed tomography (CT), magnetic resonance imaging (MRI), or endoscopic ultrasound. True left-sided gallbladder is a surgical challenge and surgical technique may need to be modified for the completion of laparoscopic cholecystectomy. In this case report, we present a case of true left-sided gallbladder that produced right-sided abdominal symptoms. Ultrasound of the abdomen failed to show the left-sided position of the gallbladder. MRI showed the gallbladder located to the left of the ligamentum teres underneath segment III of the liver. Intraoperatively, the gallbladder was grasped and retracted to the right under the falciform ligament and it was removed using classical right-sided ports with no modification to the technique. No complications were encountered intraoperatively or postoperatively. True LSG is a rare anomaly that may present with right-sided symptoms like normally positioned gallbladder. It may be missed in preoperative imaging studies and can be discovered only intraoperatively. Modification of laparoscopic ports, change in patient's position and/or surgeon's position, or conversion to open cholecystectomy may be needed for safe removal of the gallbladder. Classical technique of laparoscopic cholecystectomy is feasible for left-sided gallbladder. However, if the anatomy is not clear, modifications of the surgical technique may be necessary for the safe dissection of the gallbladder. Copyright © 2018 The Authors. Published by Elsevier Ltd..

Higher cost of single incision laparoscopic cholecystectomy due to longer operating time. A study of opportunity cost based on meta-analysis

PubMed Central

GIRABENT-FARRÉS, M.

2018-01-01

Background We aimed to calculate the opportunity cost of the operating time to demonstrate that single incision laparoscopic cholecystectomy (SILC) is more expensive than classic laparoscopic cholecystectomy (CLC). Methods We identified studies comparing use of both techniques during the period 2008–2016, and to calculate the opportunity cost, we performed another search in the same period of time with an economic evaluation of classic laparoscopy. We performed a meta-analysis of the items selected in the first review considering the cost of surgery and surgical time, and we analyzed their differences. We subsequently calculated the opportunity cost of these time differences based on the design of a cost/time variable using the data from the second literature review. Results Twenty-seven articles were selected from the first review: 26 for operating time (3.138 patients) and 3 for the cost of surgery (831 patients), and 3 articles from the second review. Both techniques have similar operating costs. Single incision laparoscopy surgery takes longer (16.90min) to perform (p <0.00001) and this difference represents an opportunity cost of 755.97 € (cost/time unit factor of 44.73 €/min). Conclusions SILC costs the same as CLC, but the surgery takes longer to perform, and this difference involves an opportunity cost that increases the total cost of SILC. The value of the opportunity cost of the operating time can vary the total cost of a surgical technique and it should be included in the economic evaluation to support the decision to adopt a new surgical technique.

The complexity of pain after laparoscopic cholecystectomy (LC) needs multi-module analgesia. Opioids are widely used for perioperative pain but associated with numerous adverse effects. We investigated the effect of parecoxib administrated preoperatively and postoperatively for analgesia after ambulatory laparoscopic cholecystectomy. 120 patients scheduled for ambulatory LC with general anesthesia were randomly assigned to three groups: group A received 40 mg parecoxib injection 30-45 min before anesthesia induction and 4 ml saline injection when gallbladder was removed; group B received 4 ml saline injection 30-45 min before anesthesia induction and 40 mg parecoxib injection when gallbladder was removed; group C received 4 ml saline injection 30-45 min before anesthesia induction and the time when gallbladder was removed. We recorded the time achieve to modified Aldrete's score > 9 in the post-anesthesia care unit (PACU) and modified Post-Anesthetic Discharge Scoring System (PADSS) > 9 in ambulatory unit. The visual analog scale (VAS) was used to assess the degree of the postoperative pain in the first 24 h, and the numbers of patients who need additional analgesic and postoperative adverse effects were also recorded. Patients of group A had a shorter length of stay (LOS) in PACU compared to these of group B and group C (32.4 ± 7.2 min vs. 39.1 ± 10.4 min and 42.2 ± 7.6 min, P < 0.05). Patients of group A also had a shorter discharge time compared to these of group B and group C (148.4 ± 39.3 min vs. 187.9 ± 47.7 min and 223.4 ± 52.5 min, P < 0.05). Moreover, patients of group A experienced reduced pain intensity, less postoperative side effect, and less additional analgesic requirement. Preoperative administration of parecoxib for postoperative analgesia provided significant effect on reducing PACU length of stay (LOS) and discharge time, and improving patient outcome after ambulatory LC.

Cholelithiasis is very common in patients with sickle cell disease (SCD) and is responsible for recurrent attacks of abdominal pain. The ideal management, especially for children, remains controversial. The purpose of the present study was to evaluate the safety and outcome of mini-laparoscopic cholecystectomy (MLC) in young children under age of 10 years with SCD. A prospective study was carried out of 75 children with SCD under 10 years of age with recurrent abdominal pains seen between August 2001 and March 2004 at Armed Forces Hospital, Khamis Mushayt, Saudi Arabia, who were screened for cholelithiasis. Twelve (16%) of the 75 children were found to have gallstones. The mean age was 7.8 years (range 4-9 years). All 12 children underwent MLC. Anaemia was corrected preoperatively in all the patients. Operative time, intraoperative complications, hospital stay, and postoperative recurrent abdominal pain were recorded. The mean operating time was 46.5 min (range: 35-65 min). Intraoperative cholangiogram failed in two children due to narrow cystic ducts. The mean hospital stay was 2.1 days (range: 2-4 days). No patient required intra-abdominal drain. The mean follow-up period was 13.4 months (range: 4-24 months). The only postoperative complication was deep jaundice 1 month postoperatively due to cholestasis, and this responded to medical treatment. None of the children had recurrent abdominal pain after MLC. Mini-laparoscopic cholecystectomy is a safe surgical procedure for the management of cholelithiasis in children with SCD and leads to improvement in the quality of life by decreasing the frequency of recurrent abdominal pain.

To determine the efficacy of ultrasound shear in laparoscopic cholecystectomy in terms of total operative time, postoperative bile leaks, gall bladder perforation rate, and postoperative bleeding from cystic artery and collateral injury to bowel and duodenum. Comparative study. Mayo Hospital, Lahore, from June 2013 to May 2014. 150 cases (75 in each group) were randomized into two groups, i.e. harmonic scalpel clipless group (HSG) versus conventional laparoscopic cholecystectomy (CLC) with electrocautery group. The above stated variables were documented. The data for age, blood loss, and drain output were positively skewed as calculated using the Shapiro-Wilk test. The histograms, Q-Q plots and box plots were analyzed for all the dependent variables. Skewed qualitative continuous data was analyzed using the Mann-Whitney U-Test. Operative time was significantly lower in HSG as compared to CLC. Median operative times were 30 minutes (IQR 10) versus 35 minutes (IQR 10) (p<0.001). HSG group had perforation rate of 5/75 (6.67%) as compated to 16/75 (21.33%) in CLC (p=0.010). Intraoperative blood loss in group Awas significantly lower than in group B (p=0.001). Postoperative median pain score was 3 (IQR 2) versus 3 (IQR 3) in HSG versus CLC, respectively. All the primary outcomes showed improved results in the ultrasound shear group as compared to the group for conventional electrocautery.

Studies have shown that same admission laparoscopic cholecystectomy (SALC) is superior to delayed laparoscopic cholecystectomy for acute cholecystitis (AC). While some proposed a"golden 72-hour" for SALC, the optimal timing remains controversial. The aim of the study was to compare the outcomes of SALC in AC patients with different time intervals from symptom onset. A retrospective analysis of 311 patients who underwent SALC for AC from June 2010-June 2015 was performed. Patients were divided into three groups based on the time interval between symptom onset and surgery: <4 days (E-SALC), 4-7 days (M-SALC), >7 (L-SALC). The mean duration of symptoms was 2(1-3), 5(4-7) and 9 (8-13) days for E-SALC, M-SALC and L-SALC, respectively (p < 0.001). Conversion rates were higher in the L-SALC group [E-SALC, 8.2% vs M-SALC, 9.6% vs L-SALC, 21.4%] (p = 0.048). The total length of stay was longer in patients with longer symptom duration [E-SALC, 4 (2-33) vs M-SALC, 2 (2-23) vs L-SALC, 7 (2-49)] (p < 0.001). Patients with AC presenting beyond 7 days of symptoms have higher conversion rates and longer length of stay associated with SALC. However, patients with less than a week of symptoms should be offered SALC. Copyright © 2016 International Hepato-Pancreato-Biliary Association Inc. Published by Elsevier Ltd. All rights reserved.

A 45-year-old woman status post laparoscopic cholecystectomy 3years ago presented with upper gastrointestinal bleeding. Endoscopy revealed hemobilia. Computed tomographic abdomen demonstrated a 2-cm aneurysm in the gall bladder fossa, consistent with a pseudoaneurysm. Initially, transcatheter coil embolization was attempted but recanalization of the aneurysm with recurrent bleeding in 2 days ensued. The aneurysm was then accessed percutaneously under ultrasound guidance and thrombin was injected into the aneurysm with subsequent complete thrombosis of the aneurysm and cessation of bleeding.

Errors in judgment during laparoscopic cholecystectomy can lead to bile duct injuries and other complications. Despite correlations between outcomes, expertise and advanced cognitive skills, current methods to evaluate these skills remain subjective, rater- and situation-dependent and non-systematic. The purpose of this study was to develop objective metrics using a Web-based platform and to obtain validity evidence for their assessment of decision-making during laparoscopic cholecystectomy. An interactive online learning platform was developed ( www.thinklikeasurgeon.com ). Trainees and surgeons from six institutions completed a 12-item assessment, developed based on a cognitive task analysis. Five items required subjects to draw their answer on the surgical field, and accuracy scores were calculated based on an algorithm derived from experts' responses ("visual concordance test", VCT). Test-retest reliability, internal consistency, and correlation with self-reported experience, Global Operative Assessment of Laparoscopic Skills (GOALS) score and Objective Performance Rating Scale (OPRS) score were calculated. Questionnaires were administered to evaluate the platform's usability, feasibility and educational value. Thirty-nine subjects (17 surgeons, 22 trainees) participated. There was high test-retest reliability (intraclass correlation coefficient = 0.95; n = 10) and internal consistency (Cronbach's α = 0.87). The assessment demonstrated significant differences between novices, intermediates and experts in total score (p < 0.01) and VCT score (p < 0.01). There was high correlation between total case number and total score (ρ = 0.83, p < 0.01) and between total case number and VCT (ρ = 0.82, p < 0.01), and moderate to high correlations between total score and GOALS (ρ = 0.66, p = 0.05), VCT and GOALS (ρ = 0.83, p < 0.01), total score and OPRS (ρ = 0.67, p = 0.04), and VCT and OPRS (ρ = 0.78, p = 0.01).

Background Considerable resources have been invested in both low- and high-fidelity simulators in surgical training. The purpose of this study was to investigate if the Fundamentals of Laparoscopic Surgery (FLS, low-fidelity box trainer) and LapVR (high-fidelity virtual reality) training systems correlate with operative performance on the Global Operative Assessment of Laparoscopic Skills (GOALS) global rating scale using a porcine cholecystectomy model in a novice surgical group with minimal laparoscopic experience. Methods Fourteen postgraduate year 1 surgical residents with minimal laparoscopic experience performed tasks from the FLS program and the LapVR simulator as well as a live porcine laparoscopic cholecystectomy. Performance was evaluated using standardized FLS metrics, automatic computer evaluations, and a validated global rating scale. Results Overall, FLS score did not show an association with GOALS global rating scale score on the porcine cholecystectomy. None of the five LapVR task scores were significantly associated with GOALS score on the porcine cholecystectomy. Conclusions Neither the low-fidelity box trainer or the high-fidelity virtual simulator demonstrated significant correlation with GOALS operative scores. These findings offer caution against the use of these modalities for brief assessments of novice surgical trainees, especially for predictive or selection purposes. PMID:26641071

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.

Myotonic dystrophy (MD) is a serious multi-systemic autosomal dominant disease. The estimated incidence is 1 in every 8000 births, with an estimated prevalence of between 2.1 and 14.3 cases per 100,000 inhabitants. Signs and symptoms vary from a severe form of congenital myopathy, present from birth and often fatal, to a classic form and a delayed form, which generally presents after the age of 50 and in which the only sign is a cataract and life expectancy is completely normal. We describe the clinical case of a 40-year-old woman with Steinert myotonic dystrophy who underwent laparoscopic cholecystectomy (under general anesthesia) for symptomatic gallbladder stones. The conduct of anesthesia in such patients must be carefully considered, as hypothermia, shivering, electrical and mechanical stimulation, and the drugs used can all trigger myotonia.

We aimed to investigate the short-term effect of laparoscopic surgery on serum thiol-disulfide homeostasis levels as a marker of oxidant stress of surgical trauma in elective laparoscopic cholecystectomy patients. Venous blood samples were collected, and levels of native thiols, total thiols, and disulfides were determined with a novel automated assay. Total antioxidant capacity (measured as the ferric-reducing ability of plasma) and serum ischemia modified albumin, expressed as absorbance units assayed by the albumin cobalt binding test, were determined. The major findings of the present study were that native thiol (283 ± 45 versus 241 ± 61 μmol/L), total thiol (313 ± 49 versus 263 ± 67 μmol/L), and disulfide (14.9 ± 4.6 versus 11.0 ± 6.1 μmol/L) levels were decreased significantly during operation and although they increased, they did not return to preoperation levels 24 hours after laparoscopic surgery compared to the levels at baseline. Disulfide/native thiol and disulfide/total thiol levels did not change during laparoscopic surgery. The decrease in plasma level of native and total thiol groups suggests impairment of the antioxidant capacity of plasma; however, the delicate balance between the different redox forms of thiols was maintained during surgery.

A powder-free surgical glove bag for retraction of the gallbladder during laparoscopic cholecystectomy.

To test the use of a simple and cheap powder-free glove bag to extract the gallbladder during laparoscopic cholecystectomy (LC). The medical records of 142 consecutive patients who had their gallbladder removed using a powder-free glove bag were reviewed. No complications in the form of bile or stone spillage during extraction were observed. The absence of complications and the low cost make routine use of the glove bag a wise option for extracting the gallbladder during LC. The use of the glove bag seems to reduce the risk of contamination with bacteria, bile, and gallstones and may reduce contamination by malignant cells in case of unexpected gallbladder carcinoma.

Currently, most patients undergoing laparoscopic cholecystectomy (LC) in Switzerland are inpatients for 2-3 days. Due to a lack of available hospital beds, we asked whether day-case surgery would be an option for patients in central Switzerland. The questions of acceptability of outpatient LC and factors contributing to the acceptability thus arose. Hundred patients suffering from symptomatic cholecystolithiasis, capable of communicating in German, and between 18 and 65 years old, were included. Patients received a pre-operative questionnaire on medical history and social situation when informed consent on surgery and participation in the study was obtained. Exclusion criteria were patients suffering from acute cholecystitis or any type of cancer; having a BMI >40 kg/m 2 ; needing conversion to open cholecystectomy or an intraoperative drainage; and non-German speakers. Surgery was performed laparoscopically. Both surgeon and patient filled in a postoperative questionnaire. The surgeon's questionnaire listed medical and technical information, and the patients' questionnaire listed medical information, satisfaction with the treatment and willingness to be released on the same day. These data from both questionnaires were grouped into social and medical factors and analysed on their influence upon willingness to accept an ambulatory procedure. No outpatient follow-up apart from checking for readmission to our hospital within 1 month after discharge was performed. Of the 100 participants, one-third was male. More than two-thirds were Swiss citizens. Only one participant was ineligible for rapid release evaluation due to need of a drainage. Among the social factors contributing to the acceptability of ambulatory care, we found nationality to be relevant; Swiss citizens preferred an inpatient procedure, whereas non-Swiss citizens were significantly more willing to return home on the same day. Household size, sex and age did not correlate with a preference for

We report successful 20 years of follow-up of a case of trans-hepatic metallic stenting (2 Gianturco® prostheses, 5 cm long, 2 cm in diameter) done for stenosed hepatico-jejunostomy anastomosis after laparoscopic CBD injury. Percutaneous transhepatic stenting and long-term placement of metallic stents need to be re-evaluated as a minimally invasive definitive treatment option for benign biliary strictures in patients with altered anatomy such as hepatico-jejunostomy or in whom re-operation involves high risk.

Authors attach the main importance to evaluation of ultrasound data and functional condition of respiratory and cardio-vascular sistem choosing the method of surgical treatment. Sparse use of laparoscopic cholecystectomy in treatment of acute cholecystitis compared with chronic may be explouned by presence of complications in patients which make problems in differentiation of tubular structures during the operation. Authors offered to use ultrasound dissection for clear identification of tubular structures and argon coagulation for hemostasis and safe mobilization of gall bladder. Stick to suggested tactics authors practically doubled the amount of performed laparoscopic cholecystectomies reducing at the same time the frequency of complications.

This study compared virtual reality (VR) training with low cost-blended learning (BL) in a structured training program.Training of laparoscopic skills outside the operating room is mandatory to reduce operative times and risks.Laparoscopy-naïve medical students were randomized in 2 groups stratified for sex. The BL group (n = 42) used E-learning for laparoscopic cholecystectomy (LC) and practiced basic skills with box trainers. The VR group (n = 42) trained basic skills and LC on the LAP Mentor II (Simbionix, Cleveland, OH). Each group trained 3 × 4 hours followed by a knowledge test concerning LC. Blinded raters assessed the operative performance of cadaveric porcine LC using the Objective Structured Assessment of Technical Skills (OSATS). The LC was discontinued when it was not completed within 80 min. Students evaluated their training modality with questionnaires.The VR group completed the LC significantly faster and more often within 80 min than BL (45% v 21%, P = .02). The BL group scored higher than the VR group in the knowledge test (13.3 ± 1.3 vs 11.0 ± 1.7, P < 0.001). Both groups showed equal operative performance of LC in the OSATS score (49.4 ± 10.5 vs 49.7 ± 12.0, P = 0.90). Students generally liked training and felt well prepared for assisting in laparoscopic surgery. The efficiency of the training was judged higher by the VR group than by the BL group.VR and BL can both be applied for training the basics of LC. Multimodality training programs should be developed that combine the advantages of both approaches.

Limy bile syndrome extending to the common bile duct (CBD) is a rare condition that lacks a standardized treatment. Laparoscopic cholecystectomy with laparoscopic choledocholithotomy by CBD exploration is preferred because it preserves the function of the sphincter of the Vater's papilla and allows treatment of both lesions. A 37-year-old man who was receiving entecavir for chronic hepatitis B developed right upper quadrant pain. Abdominal ultrasonography revealed a calcified shadow in the gallbladder and CBD. Abdominal imaging revealed a liquid-like material identified by a calcified shadow in two phases separated by a fluid-fluid level. Abdominal and 3-D drip infusion cholangiography CT showed stones in the gallbladder and CBD with limy bile. The patient underwent laparoscopic cholecystectomy and choledocholithotomy. Intraoperatively, white-yellow-colored bile and stones were drained from the CBD. A C-tube was placed. Postoperatively, remnant stones and radiopaque materials were absent. The stones comprised of >95% calcium carbonate. © 2016 Japan Society for Endoscopic Surgery, Asia Endosurgery Task Force and John Wiley & Sons Australia, Ltd.

The results at our institution with laparoscopic cholecystectomy in its first year are informed. The patients included in this study were routinely evaluated for an open procedure. The operation was done with the standard technique and equipment. In the postoperative period, ultrasound was done. Seventy-eight patients were included, 63 of them females. Age averaged 49.5 years (range 20-77). In three cases, choledocholithiasis was also demonstrated; these patients were treated with transendoscopic sphincterotomy. In 74 cases only cholelithiasis was demonstrated, two of them with shrinked gallbladder. In one case adenomyosis was found. Sixty-five cases had associated diseases which did not preclude the operation. Six cases were converted to an open cholecystectomy: two because of bleeding, the two cases with shrinked gallbladders, one with intrahepatic gallbladder, and the last one because of a Mirizzi syndrome with bile duct injury. In all cases, the conversion resolved the indication including the Mirizzi syndrome that required biliary reconstruction. No operative mortality was recorded. wound infection four, wound hematoma one, subhepatic hematoma two, and bile duct injury one.

Bile duct injuries are well-known complications of laparoscopic and open cholecystectomies. Here, we report anastomosis of the common bile duct to the transverse colon that occurred as a complication of laparoscopic cholecystectomy. To the best of our knowledge, a similar case has not been reported in the literature so far. As in our patient, persistent diarrhea (in addition to fever and icterus) can be a warning sign of complication after these procedures. Surgeons who do advanced laparoscopic techniques must be familiar with this complication. PMID:21912066

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.

Fluorescence imaging using indocyanine green (ICG) has recently been applied to laparoscopic surgery to identify cancerous tissues, lymph nodes, and vascular anatomy. Here we report the application of ICG-fluorescence imaging to visualize the boundary between the liver and subserosal tissues of the gallbladder during laparoscopic full-thickness cholecystectomy. A patient with a potentially malignant gallbladder lesion was administered 2.5-mg intravenous ICG just before laparoscopic full-thickness cholecystectomy. Intraoperative fluorescence imaging enabled the real-time delineation of both extrahepatic bile duct anatomy and hepatic parenchyma throughout the procedure, which resulted in complete removal of subserosal tissues between liver and gallbladder. Safe and feasible ICG-fluorescence imaging can be widely applied to laparoscopic hepatobiliary surgery by utilizing a biliary excretion property of ICG. © 2014 Japan Society for Endoscopic Surgery, Asia Endosurgery Task Force and Wiley Publishing Asia Pty Ltd.

Laparoscopic use of laser and monopolar electrocautery

Hunter, John G.

1991-07-01

Most general surgeons are familiar with monopolar electrocautery, but few are equally comfortable with laser dissection and coagulation. At courses across the country, surgeons are being introduced to laparoscopy and laser use in one and two day courses, and are certified from that day forward as laser laparoscopists. Some surgeons are told that laser and electrosurgery may be equally acceptable techniques for performance of laparoscopic surgery, but that a surgeon may double his patient volume by advertising 'laser laparoscopic cholecystectomy.' The sale of certain lasers has skyrocketed on the basis of such hype. The only surprise is that laparoscopic cholecystectomy complications occurring in this country seem to be more closely related to the laparoscopic access and visualization than to the choice of laser of electrocautery as the preferred instrument for thermal dissection. The purpose of this article is to: 1) Discuss the physics and tissue effects of electrosurgery and laser; 2) compare the design and safety of electrosurgical and laser delivery systems; and 3) present available data comparing laser and electrocautery application in laparoscopic cholecystectomy.

Content, evaluation, and certification of laparoscopic skills and procedure training lack uniformity among different hospitals in The Netherlands. Within the process of developing a new regional laparoscopic training curriculum, a uniform and transferrable curriculum was constructed for a series of laparoscopic procedures. The aim of this study was to determine regional expert consensus regarding the key steps for laparoscopic appendectomy and cholecystectomy using Delphi methodology. Lists of suggested key steps for laparoscopic appendectomy and cholecystectomy were created using surgical textbooks, available guidelines, and local practice. A total of 22 experts, working for teaching hospitals throughout the region, were asked to rate the suggested key steps for both procedures on a Likert scale from 1-5. Consensus was reached with Crohnbach's α ≥ 0.90. Of the 22 experts, 21 completed and returned the survey (95%). Data analysis already showed consensus after the first round of Delphi on the key steps for laparoscopic appendectomy (Crohnbach's α = 0.92) and laparoscopic cholecystectomy (Crohnbach's α = 0.90). After the second round, 15 proposed key steps for laparoscopic appendectomy and 30 proposed key steps for laparoscopic cholecystectomy were rated as important (≥4 by at least 80% of the expert panel). These key steps were used for the further development of the training curriculum. By using the Delphi methodology, regional consensus was reached on the key steps for laparoscopic appendectomy and cholecystectomy. These key steps are going to be used for standardized training and evaluation purposes in a new regional laparoscopic curriculum. Copyright © 2014 Association of Program Directors in Surgery.

Background Regarding the role of gas entry in abdomen and cardiorespiratory effects, the ability of anesthesiologists would be challenged in laparoscopic surgeries. Considering few studies in this area and the relevance of the subject, this study was performed to compare the arterial oxygen alterations before operation in comparison with after surgery between laparoscopic cholecystectomy and ovarian cystectomy. Methods In this prospective cohort, 70 consecutive women aged from 20 to 60 years who were candidate for laparoscopic cholecystectomy (n = 35) and ovarian cystectomy (n = 35) with reverse (20 degrees) and direct (30 degrees) Trendelenburg positions, respectively, with ASA class I or II were enrolled. After intubation and before operation, for the first time, the arterial blood gas from radial artery in supine position was obtained for laboratory assessment. Then, the second blood sample was collected from radial artery in supine position and sent to the lab to be assessed with the same device after 30 minutes from surgery termination. The measured variables from arterial blood gas were arterial partial pressure of oxygen (PaO2) and Oxygen saturation (SpO2) alterations. Results Total PaO2 was higher in the first measurement. The higher values of PaO2 in cholecystectomy (upward) than in ovarian cystectomy (downward) were not significant in univariate (P = 0.060) and multivariate analysis (P = 0.654). Furthermore, higher values of SpO2 in cholecystectomy (upward) than in ovarian cystectomy (downward) were not significant in univariate (P = 0.412) and multivariate analysis (P = 0.984). Conclusions In general, based on the results of this study, the values of PaO2 in cholecystectomy (upward) were not significantly higher than the values in cystectomy (downward) in laparoscopic surgeries when measured 30 minutes after surgery.

Laparoscopic cholecystectomy (LC) does not require advanced techniques, and its performance has therefore rapidly spread worldwide. However, the rate of biliary injuries has not decreased. The concept of the critical view of safety (CVS) was first documented two decades ago. Unexpected injuries are principally due to misidentification of human factors. The surgeon's assumption is a major cause of misidentification, and a high level of experience alone is not sufficient for successful LC. We herein describe tips and pitfalls of LC in detail and discuss various technical considerations. Finally, based on a review of important papers and our own experience, we summarize the following mandatory protocol for safe LC: (1) consideration that a high level of experience alone is not enough; (2) recognition of the plateau involving the common hepatic duct and hepatic hilum; (3) blunt dissection until CVS exposure; (4) Calot's triangle clearance in the overhead view; (5) Calot's triangle clearance in the view from underneath; (6) dissection of the posterior right side of Calot's triangle; (7) removal of the gallbladder body; and (8) positive CVS exposure. We believe that adherence to this protocol will ensure successful and beneficial LC worldwide, even in patients with inflammatory changes and rare anatomies.

Transversus abdominis plane (TAP) block is a recently introduced regional anesthesia technique that is used for postoperative pain reduction in some abdominal surgeries. The present study evaluated the efficacy of the TAP block on the post laparoscopic cholecystectomy pain intensity and analgesic consumption. Fifty-four patients were enrolled in three groups: TAP block with normal saline (Group 1, n = 18); TAP block with bupivacaine (Group 2, n = 18); and TAP block with bupivacaine plus sufentanil (Group 3, n = 18). The time to the first fentanyl request, fentanyl consumption in the 24 hours following surgery, and postoperative pain intensity at 30 minutes, 1 hour, 6 hours, 12 hours, and 24 hours following discharge for recovery were measured and recorded. The total amount of 24-hour fentanyl consumption was higher in Group 1 (877.8 ± 338.8 μg) than either Group 2 (566.7 ± 367.8 μg) or Group 3 (555.5 ± 356.8 μg; p = 0.03). Postoperative pain score was higher in Group 1 than intervention groups (p = 0.006); however, there was no significant difference in intervention groups. The time to the first fentanyl request in Group 1 (79.44 ± 42.2) was significantly lower than Group 3 (206.38 ± 112.7; p = 0.001). The present study demonstrated that bilateral TAP block with 0.5% bupivacaine reduces post laparoscopic cholecystectomy pain intensity and fentanyl request and prolongs time to the first analgesic request. Adding sufentanil to the block solution reduced neither pain intensity nor fentanyl further consumption. Copyright © 2015. Published by Elsevier B.V.

The study aims to evaluate the use of "critical view of safety" (CVS) for the prevention of bile duct injuries during laparoscopic cholecystectomy for acute biliary pathology as an alternative to routine intraoperative cholangiography (IOC). A policy of routine CVS to identify biliary anatomy and selective IOC for patients suspected to have common bile duct (CBD) stone was adopted. Receiver operator curves (ROCs) were used to identify cutoff values predicting CBD stones. Four hundred forty-seven consecutive, same admission laparoscopic cholecystectomies performed between August 2004 and July 2007 were reviewed. CVS was achieved in 388 (87%) patients. Where CVS was not possible, the operation was completed open. CBD stones were identified in 22/57 patients who underwent selective IOC. Preoperative liver function and CBD diameter were significantly higher in those with CBD stones (P < .001). ROC curve analysis identified preoperative cutoff values of bilirubin (35 mumol/L), alkaline phosphatase (250 IU/L), alanine aminotransferase (240 IU/L), and a CBD diameter of 10 mm, as predictive of CBD stones. No bile duct injuries occurred in this series. In acute biliary pathology, the use of CVS helps clarify the anatomy of Calot's triangle and is a suitable alternative to routine IOC. Selective cholangiography should be employed when preoperative liver function and CBD diameter are above defined thresholds.

Previous studies have indicated a correlation between indication for cholecystectomy and long-term gastrointestinal quality-of-life (QoL). The aim of the present study was to compare QoL in a post-cholecystectomy cohort with the background population and with historical controls. A post-cholecystectomy study group (on average 4 years after cholecystectomy) was compared with a control group from the background population using the Gastrointestinal Quality-of-Life Index (GIQLI). EQ-5D scores were compared with expected scores derived from recent historical data. The post-cholecystectomy study group (N = 451) had better QoL measured by the EQ-5D compared with historical controls (p < 0.001), similar total GIQLI scores as the control group (N = 390), but scored worse on the GIQLI gastrointestinal symptoms subscale score (p < 0.001). The results include an item-by-item breakdown of the GIQLI questionnaire where the scores for diarrhea, bowel urgency, bloating, regurgitation, abdominal pain, flatus, fullness, nausea, uncontrolled stools, belching, heartburn, restricted eating, and bowel frequency were found to be significantly lower (i.e. worse) in the post-cholecystectomy cohort than in the control group. The opposite was true for relationships, endurance, sexual life, physical strength, feeling fit, not being frustrated by illness, and being able to carry out leisure activities, i.e. items related to general performance and well-being. In this study, QoL after cholecystectomy was good, but there was an increased prevalence of gastrointestinal symptoms compared to the background population.

Reliable prediction of operative duration is essential for improving patient and care team satisfaction, optimizing resource utilization and reducing cost. Current operative scheduling systems are unreliable and contribute to costly over- and underestimation of operative time. We hypothesized that the inclusion of patient-specific factors would improve the accuracy in predicting operative duration. We reviewed all elective laparoscopic cholecystectomies performed at a single institution between 01/2007 and 06/2013. Concurrent procedures were excluded. Univariate analysis evaluated the effect of age, gender, BMI, ASA, laboratory values, smoking, and comorbidities on operative duration. Multivariable linear regression models were constructed using the significant factors (p < 0.05). The patient factors model was compared to the traditional surgical scheduling system estimates, which uses historical surgeon-specific and procedure-specific operative duration. External validation was done using the ACS-NSQIP database (n = 11,842). A total of 1801 laparoscopic cholecystectomy patients met inclusion criteria. Female sex was associated with reduced operative duration (-7.5 min, p < 0.001 vs. male sex) while increasing BMI (+5.1 min BMI 25-29.9, +6.9 min BMI 30-34.9, +10.4 min BMI 35-39.9, +17.0 min BMI 40 + , all p < 0.05 vs. normal BMI), increasing ASA (+7.4 min ASA III, +38.3 min ASA IV, all p < 0.01 vs. ASA I), and elevated liver function tests (+7.9 min, p < 0.01 vs. normal) were predictive of increased operative duration on univariate analysis. A model was then constructed using these predictive factors. The traditional surgical scheduling system was poorly predictive of actual operative duration (R 2  = 0.001) compared to the patient factors model (R 2  = 0.08). The model remained predictive on external validation (R 2  = 0.14).The addition of surgeon as a variable in the institutional model further improved predictive ability of the model

The management of choledocholithiasis has changed radically since the introduction of laparoscopic cholecystectomy. However, perceived technical difficulties have deterred many surgeons from treating common bile duct stones laparoscopically at the time of cholecystectomy. This has lead to reliance on endoscopic retrograde cholangiopancreatography followed by endoscopic sphincterotomy to deal with common bile duct stones. We retrospectively reviewed the charts of patients who had laparoscopic common bile duct exploration at Downe Hospital between December 1999 and August 2001. Among 149 laparoscopic cholecystectomies done by our group in this period, 10 patients (6.7%) underwent laparoscopic CBD exploration, three by the transcystic technique and seven by choledochotomy. Three patients (2%) had unsuspected stones found on routine per- operative cholangiogram. The mean operative time was 2.34hrs (range 1.50-3.30hrs). The mean hospital post- operative stay was 3 days (range 1-6 days). Post-operative morbidity was zero. Stone clearance was achieved in all cases. We conclude, laparoscopic exploration of the common bile duct is relatively safe and straightforward method. The key skill required is the ability to perform laparoscopic suturing with confidence.

Laparoscopic cholecystectomy (LC) is replacing conventional open cholecystectomy (OC) as a preferred surgical method for treating complicated biliary tract disorders. However, there have been few studies assessing the impact of staged bile duct drainage (BDD) on costs and clinical outcomes for either surgical approach. This study evaluated the impact of surgical technique and BDD on resource utilization and complication rates. This study included 2778 cholecystectomy patients treated for benign biliary tract diseases in 80 academic and 81 community hospitals. For both OC and LC patients, the following variables were analysed: demographics, clinical data, length of stay (LOS), total charges (TC; US$), procedure-related complications and hospital type. Multivariate analyses were used to determine the impact of BDD on LOS, TC and complication rates. Of the 2778 cholecystectomy patients in the study, 2255 (81.2%) underwent LC. Inflammation was diagnosed in 55.6% of OC patients and 36.0% of LC patients. Complication was 9.4% in OC cases and 4.7% in LC cases. BDD was performed in 14.5% of OC cases and in 7.6% of LC cases. Diagnosis of inflammation, presence of co-morbidities and BDD each had a significant impact on LOS and TC. After risk adjustment, LC was associated with a reduction in LOS and TC, while BDD resulted in greater LOS and TC. LC and BDD were significantly associated with complications. The study suggested that BDD utilized more resources and had higher rates of complications. LC remains an appropriate procedure for cholecystectomy patients. Further study will be needed to evaluate the effect of pre-operative or post-operative BDD on quality of care.

The value of robotics in general surgery may be for advanced minimally invasive procedures. Unlike other specialties, formal fellowship training opportunities for robotic general surgery are few. As a result, most surgeons currently develop robotic skills in practice. Our goal was to determine whether robotic cholecystectomy is a safe and effective bridge to advanced robotics in general surgery. Before performing advanced robotic procedures, 2 surgeons completed the Intuitive Surgical da Vinci training course and agreed to work together on all procedures. Clinical surgery began with da Vinci cholecystectomy with a plan to begin advanced procedures after at least 10 cholecystectomies. We performed a retrospective review of our pilot series of robotic cholecystectomies and compared them with contemporaneous laparoscopic controls. The primary outcome was safety, and the secondary outcome was learning curve. There were 16 procedures in the robotics arm and 20 in the laparoscopic arm. Two complications (da Vinci port-site hernia, transient elevation of liver enzymes) occurred in the robotic arm, whereas only 1 laparoscopic patient (slow to awaken from anesthetic) experienced a complication. None was significant. The mean time required to perform robotic cholecystectomy was significantly longer than laparoscopic surgery (91 v. 41 min, p < 0.001). The mean time to clear the operating room was significantly longer for robotic procedures (14 v. 11 min, p = 0.015). We observed a trend showing longer mean anesthesia time for robotic procedures (23 v. 15 min). Regarding learning curve, the mean operative time needed for the first 3 robotic procedures was longer than for the last 3 (101 v. 80 min); however, this difference was not significant. Since this experience, the team has confidently gone on to perform robotic biliary, pancreatic, gastresophageal, intestinal and colorectal operations. Robotic cholecystectomy can be performed reliably; however, owing to the significant

Minimally invasive techniques are used more and more frequently. Since conventional laparoscopic approach has been the gold standard, surgeons in their effort to further reduce the invasiveness of conventional laparoscopic cholecystectomy have adopted Single Incision approach. The widespread adoption of robotics has led to the inevitable hybridization of robotic technology with laparoendoscopic single-site surgery (LESS). As a result, employment of the da Vinci surgical system may allow greater surgical maneuverability, improving ergonomics. A review of the English literature was conducted to evaluate all robotic single port cholecystectomy performed till today. Demographic data, operative parameters, postoperative outcomes and materials used for the operation were collected and assessed. A total of 12 studies, including 501 patients were analyzed. Demographics and clinical characteristics of the patients was heterogeneous, but in most studies a mean BMI <30 was recorded. Intraoperative metrics like operative time, estimated blood loss and conversion rate were comparable with those in multiport conventional laparoscopy. Robotic single port cholecystectomy is a safe and feasible alternative to conventional multiport laparoscopic or manual robotic approach. However, current data do not suggest a superiority of robotic SILC over other established methods.

Association between esophageal achalasia/ gastroesophageal reflux disease (GERD) and cholelithiasis is not clear. Epidemiological data are controversial due to different methodologies applied, the regional differences and the number of patients involved. Results of concomitant cholecistectomy associated to surgical treatment of both diseases regarding safety is poorly understood. To analyze the prevalence of cholelithiasis in patients with esophageal achalasia and gastroesophageal reflux submitted to cardiomyotomy or fundoplication. Also, to evaluate the safety of concomitant cholecistectomy. Retrospective analysis of 1410 patients operated from 2000 to 2013. They were divided into two groups: patients with GERD submitted to laparocopic hiatoplasty plus Nissen fundoplication and patients with esophageal achalasia to laparoscopic cardiomyotomy plus partial fundoplication. It was collected epidemiological data, specific diagnosis and subgroups, the presence or absence of gallstones, surgical procedure, operative and clinical complications and mortality. All groups/subgroups were compared. From 1,229 patients with GERD or esophageal achalasia, submitted to laparoscopic cardiomyotomy or fundoplication, 138 (11.43%) had cholelitiasis, occurring more in females (2.38:1) with mean age of 50,27 years old. In 604 patients with GERD, 79 (13,08%) had cholelitiasis. Lower prevalence occurred in Barrett's esophagus patients 7/105 (6.67%) (p=0.037). In 625 with esophageal achalasia, 59 (9.44%) had cholelitiasis, with no difference between chagasic and idiopathic forms (p=0.677). Complications of patients with or without cholecystectomy were similar in fundoplication and cardiomyotomy (p=0.78 and p=1.00).There was no mortality or complications related to cholecystectomy in this series. Prevalence of cholelithiasis was higher in patients submitted to fundoplication (GERD). Patients with chagasic or idiopatic forms of achalasia had the same prevalence of cholelithiasis. Gallstones

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

Valid and user-friendly prediction models for conversion to open cholecystectomy allow for proper planning prior to surgery. The Cairns Prediction Model (CPM) has been in use clinically in the original study site for the past three years, but has not been tested at other sites. A retrospective, single-centred study collected ultrasonic measurements and clinical variables alongside with conversion status from consecutive patients who underwent laparoscopic cholecystectomy from 2013 to 2016 in The Townsville Hospital, North Queensland, Australia. An area under the curve (AUC) was calculated to externally validate of the CPM. Conversion was necessary in 43 (4.2%) out of 1035 patients. External validation showed an area under the curve of 0.87 (95% CI 0.82-0.93, p = 1.1 × 10 -14 ). In comparison with most previously published models, which have an AUC of approximately 0.80 or less, the CPM has the highest AUC of all published prediction models both for internal and external validation.

Our purpose was to assess the prophylactic antiemetic effects of ondansetron versus granisetron for laparoscopic cholecystectomy. We searched Medline, Cochrane Central Register of Controlled Trials, PubMed, Embase, Science Citation Index Expanded, Foreign Medical Journal Full-Text Service, China National Knowledge Infrastructure Whole Article Database, Chinese Biomedical Database, and the Google Scholar. We calculated the risk ratio (RR) with 95% confidence interval (CI) for dichotomous data. The χ(2) test and I(2) value were used to assess heterogeneity. The merged early incidence of postoperative nausea and vomiting (PONV) in ondansetron group (42.9%) was higher than granisetron group (34.3%) (RR = 1.25, 95% CI, 0.82-1.92, P=0.31, I(2) = 48%). The merged total incidence of PONV in ondansetron group (38.7%) was higher than granisetron group (34.2%) (RR = 1.13, 95% CI, 0.82-1.56, P = 0.46, I(2) = 39%), although these differences were not statistically significant. Ondansetron is equivalent to granisetron for preventing early and total incidence of PONV after laparoscopic cholecystectomy.

Background. For Tis and T1a gallbladder cancer (GbC), laparoscopic cholecystectomy can provide similar survival outcomes compared to open cholecystectomy. However, for patients affected by resectable T1b or more advanced GbC, open approach radical cholecystectomy (RC), consisting in gallbladder liver bed resection or segment 4b-5 bisegmentectomy, with locoregional lymphadenectomy, is considered the gold standard while minimally invasive RC (MiRC) is skeptically considered. Aim. To analyze current literature on perioperative and oncologic outcomes of MiRC for patients affected by GbC. Methods. A Medline review of published articles until June 2016 concerning MiRC for GbC was performed. Results. Data relevant for this review were presented in 13 articles, including 152 patients undergoing an attempt of MiRC for GbC. No randomized clinical trial was found. The approach was laparoscopic in 147 patients and robotic in five. Conversion was required in 15 (10%) patients. Postoperative complications rate was 10% with no mortality. Long-term survival outcomes were reported by 11 studies, two of them showing similar oncologic results when comparing MiRC with matched open RC. Conclusions. Although randomized clinical trials are still lacking and only descriptive studies reporting on limited number of patients are available, current literature seems suggesting that when performed at highly specialized centers, MiRC for GbC is safe and feasible and has oncologic outcomes comparable to open RC.

A 75-year-old woman suffering from symptomatic cholelithiasis was admitted to our hospital for elective laparoscopic cholecystectomy (LC). Intraoperatively, because of severe inflammation and dense adhesions in the region of the Calot triangle and bleeding arising from the porta hepatis which obscured the operating field, the method was converted to a conventional open approach. Copious hemostasis was achieved using sutures, clips and diathermy, and no bile duct or vascular injuries were recognized intraoperatively. Because of severe right upper quadrant abdominal pain and significant deterioration of the liver function tests (LFTs) on the first postoperative day, the patient underwent a Doppler ultrasound scan which showed absence of blood flow at the level of porta hepatis. Urgent relaparotomy revealed an ischemic liver on the right, a transected common bile duct at the level of its confluence, a divided and ligated right hepatic artery and thrombosed portal vein down to its confluence. Thrombectomy and reconstruction of the portal vein were performed to salvage the left hemiliver, and after restoration of blood flow to the left hemiliver, a right hemihepatectomy and a Roux-en-Y hepaticojejunostomy on the left were performed. Liver resection serves an important role in the case of parenchymal necrosis due to combined biliary, hepatic artery and portal vein injury following laparoscopic cholecystectomy and moreover, the operation can be safely performed in the acute setting.

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.

The study recruited 120 patients of either gender, age greater than 18 years and indicated for laparoscopic cholecystectomy (LC). Intra-operatively all patients were evaluated using the new scoring system. The scoring system included five aspects; appearance and adhesion of Gall Bladder (GB), distension or contracture degree of GB, ease in access, local or septic complications, and time required for cystic artery and duct identification. The scoring system ranges from 0 to 10, classified as score of <2 being considered easy, 2 to 4 moderate, 5-7 very difficult, and 8 to 10, extreme. Patient demographic data (i.e. age, gender), co-morbidities, intra-operative scores using the scoring system and conversion to open were recorded. The data was analysed using statistical analysis software SPSS (IBM). Among one hundred and twenty participants, sixty seven percent were females and the mean age (years) was 43.05 ± 14.16. Co-morbidities were present in twenty percent patients with eleven diagnosed with diabetes, six with hypertension and five with both hypertension and diabetes. The conversion rate to open surgery was 6.7%. The overall mean intra-operative scores were 3.52 ± 2.23; however significant difference was seen in mean operative score of converted to open and those not converted to open (8.00 ± 0.92 Vs. 3.20 V 1.92; p-value = 0.001). Among eight cases converted to open, three (37.5%) were in very difficult category while five (62.5%) were in extreme category. Moreover, age greater than 40 years and being diabetic were also the risk factors for conversion to open surgery. The new intra-operative scoring system is a valuable assessment tool to predict difficult laparoscopic cholecystectomy and conversion parameters to open surgery and

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.

A 39-year-old woman with acute cholecystitis and gallstones underwent laparoscopic cholecystectomy. She suffered from recurrent episodes of cholangitis due to injury of the major bile ducts during laparoscopic cholecystectomy. Hepatobiliary scintigraphy with Tc-99m Sn-N-pyridoxyl-5-methyltryptophan was performed. Although normal bile excretion was found from the left hepatic duct to the percutaneous transhepatic biliary drainage (PTBD) tube, excretion from the right hepatic lobe was prolonged. Scintigraphy with Tc-99m diethylenetriaminepentaacetic acid-galactosyl human serum albumin demonstrated atrophy of the right hepatic lobe and enlargement of the left hepatic lobe. Cholangiography via the PTBD tube revealed complete obstruction of the left hepatico-jejunal anastomosis and could not enhance the right intrahepatic bile duct. A right hepatic lobectomy was performed because of the atrophy, glissonitis and the absence of an appropriate bile duct for reconstruction. Postoperatively she was active and exhibited no evidence of recurrent cholangitis.

The management of choledocholithiasis has changed radically since the introduction of laparoscopic cholecystectomy. However, perceived technical difficulties have deterred many surgeons from treating common bile duct stones laparoscopically at the time of cholecystectomy. This has lead to reliance on endoscopic retrograde cholangiopancreatography followed by endoscopic sphincterotomy to deal with common bile duct stones. We retrospectively reviewed the charts of patients who had laparoscopic common bile duct exploration at Downe Hospital between December 1999 and August 2001. Among 149 laparoscopic cholecystectomies done by our group in this period, 10 patients (6.7%) underwent laparoscopic CBD exploration, three by the transcystic technique and seven by choledochotomy. Three patients (2%) had unsuspected stones found on routine per- operative cholangiogram. The mean operative time was 2.34hrs (range 1.50-3.30hrs). The mean hospital post- operative stay was 3 days (range 1-6 days). Post-operative morbidity was zero. Stone clearance was achieved in all cases. We conclude, laparoscopic exploration of the common bile duct is relatively safe and straightforward method. The key skill required is the ability to perform laparoscopic suturing with confidence.

2006-05-01

The technique of laparoscopic cholecystectomy (LC) still has areas of refinements. To decrease the number of ports, a cannula may be replaced by a percutaneous suture suspension of the gallbladder. The risk of tissue injury caused by repeat blind extraction and insertion of various instruments in and out of the abdomen may be decreased by the use of the multipurpose harmonic dissector. One hundred consecutive patients with symptomatic cholelithiasis underwent 3-port LC entirely performed by harmonic dissector without cystic duct and artery clipping. In 8 cases, a fourth trocar was necessary. In 2 cases, the cystic duct was clipped after an unsafe ultrasound sealing. In 1 case, continuous bleeding from the liver required the use of diathermy. No common bile duct injury was registered. The 3-port harmonic LC is a feasible, effective, and safe technique.

In patients with stones in their bile ducts and gallbladders, cholecystectomy is generally recommended after endoscopic sphincterotomy and clearance of bile duct stones. However, only approximately 10% of patients with gallbladders left in situ will return with further biliary complications. Expectant management is alternately advocated. In this study, we compared the treatment strategies of laparoscopic cholecystectomy and gallbladders left in situ. We randomized patients (>60 years of age) after endoscopic sphincterotomy and clearance of their bile duct stones to receive early laparoscopic cholecystectomy or expectant management. The primary outcome was further biliary complications. Other outcome measures included adverse events after cholecystectomy and late deaths from all causes. One hundred seventy-eight patients entered into the trial (89 in each group); 82 of 89 patients who were randomized to receive laparoscopic cholecystectomy underwent the procedure. Conversion to open surgery was needed in 16 of 82 patients (20%). Postoperative complications occurred in 8 patients (9%). Analysis was by intention to treat. With a median follow-up of approximately 5 years, 6 patients (7%) in the cholecystectomy group returned with further biliary events (cholangitis, n = 5; biliary pain, n = 1). Among those with gallbladders in situ, 21 (24%) returned with further biliary events (cholangitis, n = 13; acute cholecystitis, n = 5; biliary pain, n = 2; and jaundice, n = 1; log rank, P = .001). Late deaths were similar between groups (cholecystectomy, n = 19; gallbladder in situ, n = 11; P = .12). In the Chinese, cholecystectomy after endoscopic treatment of bile duct stones reduces recurrent biliary events and should be recommended.

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.

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.

To describe and evaluate a new cholecystectomy technique combining classical dissection with currently available mini-instrumentation (3 and 5 mm) and gallbladder removal through a short gastrotomy. After a feasibility study, we set up a protocol for this procedure using instrumentation currently available on the market. We performed 106 procedures, including 99 in a prospective study between January 2008 and July 2010. Cholecystectomy was performed with the described technique in 99 of 106 eligible patients (22 males and 77 females, mean age 45.8 years (range 18-77); median BMI 26.4 kg/m2 (range 22-36)). Forty-eight patients had at least one gallstone larger than 10 mm. There were no postoperative gastric complications and recovery was always rapid. This procedure is technically feasible, safe and reproducible. The results are good, with minimal abdominal wall trauma. Normal physical activity can be resumed rapidly with no risk of incisional hernia.

This study examined the impact of virtual reality (VR) surgical simulation on improvement of psychomotor skills relevant to the performance of laparoscopic cholecystectomy. Sixteen surgical trainees performed a laparoscopic cholecystectomy on patients in the operating room (OR). The participants were then randomized to receive VR training (ten repetitions of all six tasks on the Minimally Invasive Surgical Trainer-Virtual Reality (MIST-VR)) or no training. Subsequently, all subjects performed a further laparoscopic cholecystectomy in the OR. Both operative procedures were recorded on videotape, and assessed by two independent and blinded observers using predefined objective criteria. Time to complete the procedure, error score and economy of movement score were assessed during the laparoscopic procedure in the OR. No differences in baseline variables were found between the two groups. Surgeons who received VR training performed laparoscopic cholecystectomy significantly faster than the control group (P=0.021). Furthermore, those who had VR training showed significantly greater improvement in error (P=0.003) and economy of movement (P=0.003) scores. Surgeons who received VR simulator training showed significantly greater improvement in performance in the OR than those in the control group. VR surgical simulation is therefore a valid tool for training of laparoscopic psychomotor skills and could be incorporated into surgical training programmes.

We report management of anesthesia in a patient suffering from glucose-6-phosphate dehydrogenase (G6PD) deficiency, a condition that induces acute hemolysis when associated with surgical stress and infection, or following the application of oxidant drugs. A 5 year-old-male patient, suffering from G6PD deficiency was scheduled for laparoscopic cholecystectomy. The patient had exhibited signs of hemolysis during the course of various infections and after ingesting fava beans (favism). Anesthesia was induced with midazolam and vecuronium and maintained with nitrous oxide in oxygen and sevoflurane. There was no hemolytic change during the perioperative period. It was clear that this combination of drugs provided safe anesthesia for the G6PD patient in the present study. The most important considerations for patients with G6PD deficiency is firstly, the avoidance of oxidative stress, which can be caused by a variety of different conditions, and secondly, the use of anti-oxidative anesthetic drugs.

A prospective study was carried out to investigate the value of preoperative ultrasound findings for predicting difficulties encountered during laparoscopic cholecystectomy (LC). Altogether 160 consecutive patients with symptomatic gallbladder (GB) disease (130 females, 30 males) referred to the Jordan University Hospital were recruited for the purpose of this study. All patients underwent detailed ultrasound examination 24 hours prior to LC. The overall difficulty score (ODS), as a dependent variable, was based on the following operative parameters: duration of surgery, bleeding, dissection of Calot's triangle, dissection of gallbladder wall, adhesions, spillage of bile, spillage of stone, and difficulty of gallbladder extraction. Multiple regression analysis was used to assess the significance of the following preoperative ultrasound variables (independent) for predicting the variation in the ODS: size of the GB, number of GB stones, size of stones, location of GB stones, thickness of GB wall, common bile duct (CBD) diameter, and liver size. Only thickness of GB wall and CBD diameter were found to be significant predictors of the variation in the ODS (adjusted R2 = 0.25). We conclude that the preoperative ultrasound examination is of value for predicting difficulties encountered during LC, but it is not the sole predictor.

During laparoscopic cholecystectomy, a large stone burden may cause difficulty when extracting the gallbladder through the abdominal wall. Currently, the alternatives available to the surgeon include increasing the incision, removing stones singly, or utilizing complex fragmentation techniques like the pulsed dye laser. We have employed an electromechanical rotary gallstone lithotrite (RGL) to fragment stones to an aspiratable size. Initially, cholesterol spheres were pulverized in a latex balloon to demonstrate the efficacy of the device. Then, human gallstones were placed in the balloon and reduced to fragments less than or equal to 1 mm from initial sizes of 4-24 mm. Human stones were then inserted in ex vivo porcine gallbladders in a controlled experiment and treated with the device. Ten out of 12 tests were completed within 30 s; one test required 49 s and one 105 s to achieve complete fragmentation. Blinded histological evaluation demonstrated that tissue abrasion caused by use of the device would not interfere with the diagnosis of unsuspected malignancy. Clinical trials have now commenced under the auspices of the hospital ethical committee.

Background: Pneumoperitoneum in laparoscopic procedures is associated with hemodynamic response, due to the release of catecholamines and vasopressin. Magnesium and clonidine have been used to attenuate such hemodynamic responses by inhibiting release of these mediators. We conducted this randomized, double-blinded study to assess which of the two attenuates hemodynamic response better. Materials and Methods: Ninety American Society of Anesthesiologists health status Classes I and II patients posted for elective laparoscopic cholecystectomy were randomized into three groups of thirty patients each. Group C received injection clonidine 1 μg/kg diluted in 10 mL normal saline over 10 min, prior to pneumoperitoneum. Group M received injection magnesium sulfate 50 mg/kg diluted in 10 mL normal saline over 10 min, prior to pneumoperitoneum. Group NS received 10 mL normal saline intravenously over 10 min, prior to pneumoperitoneum. Hemodynamic parameters were recorded before induction (baseline values), at the end of magnesium sulfate/clonidine/saline administration and before pneumoperitoneum (P0), 5 min (P5), 10 min (P10), 20 min (P20), 30 min (P30), and 40 min (P40) after pneumoperitoneum. Results: Systolic blood pressure, diastolic blood pressure (DBP), mean arterial pressure (MAP), and heart rate (HR) were all significantly higher in the normal saline group compared to magnesium and clonidine. On comparing patients in Group M and Group C, DBP, MAP, and HR were significantly lower in the magnesium group. Mean extubation time and time to response to verbal commands were significantly longer in the magnesium group. Conclusions: Both magnesium and clonidine attenuated the hemodynamic response to pneumoperitoneum. However, magnesium 50 mg/kg, attenuated hemodynamic response better than clonidine 1 μg/kg.

Carbon dioxide (CO2) pneumoperitoneum together with an increased intraabdominal pressure (IAP) induces a hemodynamic stress response, diminishes urine output, and may compromise splanchnic perfusion. A new retractor method may be less traumatic. Accordingly, 30 ASA physical status I or II patients undergoing laparoscopic cholecystectomy were randomly allocated to a CO2 pneumoperitoneum (IAP 12-13 mm Hg) (control) or to a gasless abdominal wall lift method (retractor) group. Anesthesia and intravascular fluids were standardized. Direct mean arterial pressure (MAP), urine output, urine-N-acetyl-beta-D-glucosaminidase (U-NAG), arterial blood gases, gastric mucosal PCO2, and intramucosal pH (pHi) were measured. Normoventilation was instituted in all patients. MAP increased (P < 0.001) only with CO2 pneumoperitoneum. Minute volume of ventilation had to be increased by 35% with CO2 insufflation. PaCO2 was significantly higher (P < 0.05) for 3 h postoperatively in the control group. Diuresis was less (P < 0.01) and U-NAG levels (P < 0.01) higher in the control group. The pHi decreased after induction of pneumoperitoneum up to three hours postoperatively and remained intact in the retractor group. We conclude that the retractor method for laparoscopic cholecystectomy ensures stable hemodynamics, prevents respiratory acidosis, and provides protection against biochemical effects, which reveal the renal and splanchic ischemia caused by CO2 insufflation. A mechanical retractor method (gasless) was compared with conventional CO2 pneumoperitoneum for laparoscopic cholestectomy. The gasless method ensured stable hemodynamics, prevented respiratory acidosis, and provided protection against the renal and splanchnic ischemia seen with CO2 pneumoperitoneum.

We realize a prospective study about laparoscopic ultrasonography performed in 37 cases with laparoscopic surgical treatment. The Aloka SSD 2000 mobile scanner is used. This system make possible the use of an linear-array transducer, with mechanical flexibility and availability of Doppler analysis. Most frequently we used intraoperative ultrasonography in laparoscopic cholecystectomy as an alternative for cholangiography to exclude CBD pathology. Because of various surgical pathology with laparoscopic approach, the laparoscopic ultrasonography utilization range was vastly. In all the cases we could performed the laparoscopic ultrasonography. In 6 of 27 cases with laparoscopic cholecystectomy we found pathological disorders of bile ducts. CBD with diameter found between 5-12 mm. We properly saw the distal segment of CBD in 23 cases (89.2%), and common hepatic duct in 26 cases (97.3%). The quality of visualization was very good in 21 cases (83.8%) and moderate in 6 cases (16.2%). We easy identify CBD stones and we successfully used Doppler color mode in differentiating vascular from non-vascular from non-vascular structures. Laparoscopic ultrasonography performed in a case with left colon cancer excluded liver metastasis and lymph nodes metastasis. 1. Laparoscopic ultrasonography combines the advantages of diagnostic laparoscopy and intraoperative contact ultrasonography; 2. Laparoscopic ultrasonography is a simple and very efficient intraoperative examination procedure; 3. Laparoscopic ultrasonography is the technique to choose in CBD intraoperative exploration; 4. Laparoscopic ultrasonography improve abdominal malignancy exploration, thus modifying therapeutic decisions; 5. Color Doppler mode guides the surgeon's steps in difficult directions.

Introduction Laparoscopic Cholecystectomy (LC) is the most frequently performed elective daycare surgery and provision of postoperative pain relief is of importance. After laparoscopic cholecystectomy shoulder and abdominal pain causes considerable distress. Visceral pain during coughing, respiration and mobilization increases morbidity, hospital stay and costs. Aim To compare the analgesic efficacy of intraperitoneally instilled equipotent concentrations of bupivacaine and ropivacaine versus placebo in relieving postoperative pain after laparoscopic cholecystectomy when used as a part of multimodal analgesia. Materials and Methods In this randomised, prospective, double blind, placebo controlled study, 90 ASA Class I or II patients were randomly divided into three groups of 30 each. Group S received intraperitoneal infiltration with 35 ml of 0.9% normal saline, Group B with 35 ml of 0.25% bupivacaine and Group R with 35 ml of 0.375% ropivacaine. All groups received standard general endotracheal anaesthesia and analgesia with IV paracetamol 15 mg/kg and diclofenac 1.5 mg/kg. Numerical Rating Scale (NRS) score of analgesia at rest and on cough/movement, duration of analgesia, haemodynamic parameters, need for a rescue analgesic (IV tramadol 1 mg/kg) was recorded and adverse effects of procedure and drugs if any were monitored. Data was analysed with SPSS statistical software version 21.0. One way ANOVA or the Kruskal–Wallis test was used to compare continuous data across all three groups as appropriate. Subsequent analysis of continuous data between two groups was achieved by Tukey’s post hoc test. Significance was accepted as p<0.05.

To determine whether LapSim training (version 3.0; Surgical Science Ltd, Göteborg, Sweden) to criteria for novice PGY1 surgical residents had predictive validity for improvement in the performance of laparoscopic cholecystectomy. In all, 21 PGY1 residents performed laparoscopic cholecystectomies in pigs after minimal training; their performance was evaluated by skilled laparoscopic surgeons using the validated tool GOALS (global operative assessment of laparoscopic operative skills: depth perception, bimanual dexterity, efficiency, tissue handling, and overall competence). From the group, 10 residents trained to competency on the LapSim Basic Skills Programs (camera navigation, instrument navigation, coordination, grasping, lifting and grasping, cutting, and clip applying). All 21 PGY1 residents again performed laparoscopic cholecystectomies on pigs; their performance was again evaluated by skilled laparoscopic surgeons using GOALS. Additionally, we studied the rate of learning to determine whether the slow or fast learners on the LapSim performed equivalently when performing actual cholecystectomies in pigs. Finally, 6 categorical residents were tracked, and their clinical performance on all of the laparoscopic cholecystectomies in which they were "surgeon, junior" was prospectively evaluated using the GOALS criteria. We found a statistical improvement of depth perception in the operative performance of cholecystectomies in pigs in the group trained on the LapSim. In the other 4 domains, a trend toward improvement was observed. No correlation between being a fast learner and the ultimate skill was demonstrated in the clinical performance of laparoscopic cholecystectomies. We did find that the fast learners on LapSim all were past or current video game players ("gamers"); however, that background did not translate into better clinical performance. Using current criteria, we doubt that the time and effort spent training novice PGY1 Surgical Residents on the basic

The applications of laparoendoscopic single-site (LESS) surgery, including cholecystectomy, are occurring quickly, although little is generally known about issues associated with the learning curve of this new technique including operative time, conversion rates, and safety. We prospectively followed all patients undergoing LESS cholecystectomy, and compared operations undertaken at our institutions in cohorts of 25 patients with respect to operative times, conversion rates, and complications. One-hundred fifty patients of mean age 46 years underwent LESS cholecystectomy. No significant differences in operative times were demonstrable between any of the 25-patient cohorts operated on at our institution. A significant reduction in operative times (p < 0.001) after completion of 75 LESS procedures was, however, identified with the experience of a single surgeon. No significant reduction in the number of procedures requiring an additional trocar(s) or conversion to open operations was observed after completion of 25 LESS cholecystectomies. Complication rates were low, and not significantly different between any 25-patient cohorts. For surgeons proficient with multi-incision laparoscopic cholecystectomy, the learning curve for LESS cholecystectomy begins near proficiency. Operative complications and conversions were infrequent and unchanged across successive 25-patient cohorts, and were similar to those reported for multi-incision laparoscopic cholecystectomy after the learning curve.

Background and Aims: Poorly managed acute postoperative pain may result in prolonged morbidity. Various pharmacotherapies have targeted this, but research on an ideal preemptive analgesic continues, taking into account drug-related side effects. Considering the better tolerability profile of tapentadol, we assessed its role as a preemptive analgesic in the reduction of postoperative analgesic requirements, after laparoscopic cholecystectomy. Material and Methods: In a prospective-double-blinded fashion, sixty patients posted for above surgery, were randomized to receive tablet tapentadol 75 mg (Group A) or starch tablets (Group B) orally, an hour before induction of general anesthesia. Perioperative analgesic requirement, time to first analgesia, pain, and sedation score were compared for first 24 h during the postoperative period and analyzed by one-way analysis of variance test. A P < 0.05 was considered significant. Results: Sixty patients were analyzed. The perioperative analgesic requirement was significantly lower in Group A. Verbal numerical score was significantly lower in Group A at the time point, immediately after shifting the patient to the postanesthesia care unit. Ramsay sedation scores were similar between the groups. No major side effects were observed except for nausea and vomiting in 26 cases (10 in Group A, 16 in Group B). Conclusion: Single preemptive oral dose of tapentadol (75 mg) is effective in reducing perioperative analgesic requirements and acute postoperative pain, without added side effects. It could be an appropriate preemptive analgesic, subjected to future trials concentrating upon its dose-response effects. PMID:28096581

Many surgeons attempting Laparo-Endoscopic Single Site (LESS) cholecystectomy have found the operation difficult, which is inconsistent with our experience. This article is an attempt to promote a standardized approach that we feel surgeons with laparoscopic skills can perform safely and efficiently. This is a four-trocar approach consistent with the four incisions utilized in conventional laparoscopic cholecystectomy. After administration of general anesthesia, marcaine is injected at the umbilicus and a 12-mm vertical incision is made through the already existing anatomical scar of the umbilicus. A single four-trocar port is inserted. A 5-mm deflectable-tip laparoscope is placed through the trocar at the 8 o'clock position, a bariatric length rigid grasper is inserted through the trocar at the 4 o'clock position (to grasp the fundus), and a rigid bent grasper is placed through the 10-mm port (to grasp the infundibulum). This arrangement of the instruments promotes minimal internal and external instrument clashing with simultaneous optimization of the operative view. This orientation allows retraction of the gallbladder in a cephalad and lateral direction, development of a window between the gallbladder and the liver which promotes the "critical view" of the cystic duct and artery, and provides triangulation with excellent visualization of the operative field. The operation is concluded with diaphragmatic irrigation of marcaine solution to minimize postoperative pain. Standardization of LESS cholecystectomy will speed adoption, reduce intraoperative complications, and improve the efficiency and safety of the approach.

Few studies have assessed the impact of obesity on laparoscopic cholecystectomy (LC) in pediatric patients. Children who underwent LC were identified from the 2012 to 2013 American College of Surgeons' National Surgical Quality Improvement Program Pediatrics data. Patient characteristics, operative details, and outcomes were compared. Multivariable logistic regression was utilized to identify predictors of increased operative time (OT) and duration of anesthesia (DOAn). In total, 1757 patients were identified. Due to low rates of obesity in children <9 years old, analyses were limited to those 9-17 (n = 1611, 43% obese). Among obese children, 80.6% were girls. A higher proportion of obese patients had diabetes (3.0% versus 1.0%, P < .01) and contaminated or dirty/infected wounds (15.1% versus 9.4%, P < .01). Complication rates were low. The most frequent indications for surgery were cholelithiasis/biliary colic (34.3%), chronic cholecystitis (26.9%), and biliary dyskinesia (18.2%). On multivariable analysis, obesity was an independent predictor of OT >90 (odds ratio [OR] 2.02; 95% confidence interval [95% CI] 1.55-2.63), and DOAn >140 minutes (OR 1.86; 95% CI 1.42-2.43). Obesity is an independent risk factor for increased OT in children undergoing LC. Pediatric surgeons and anesthesiologists should be prepared for the technical and physiological challenges that obesity may pose in this patient population.

Skill transfer represents an important issue in surgical education, and is not well understood. The aim of this randomized study is to assess the transferability of surgical skills between two laparoscopic abdominal procedures using the virtual reality simulator in surgical novices. From September 2016 to July 2017, 44 surgical novices were randomized into two groups and underwent a proficiency-based basic training consisting of five selected simulated laparoscopic tasks. In group 1, participants performed an appendectomy training on the virtual reality simulator until they reached a defined proficiency. They moved on to the tutorial procedural tasks of laparoscopic cholecystectomy. Participants in group 2 started with the tutorial procedural tasks of laparoscopic cholecystectomy directly. Finishing the training, participants of both groups were required to perform a complete cholecystectomy on the simulator. Time, safety and economy parameters were analysed. Significant differences in the demographic characteristics and previous computer games experience between the two groups were not noted. Both groups took similar time to complete the proficiency-based basic training. Participants in group 1 needed significantly less movements (388.6 ± 98.6 vs. 446.4 ± 81.6; P < 0.05) as well as shorter path length (810.2 ± 159.5 vs. 945.5 ± 187.8 cm; P < 0.05) to complete the cholecystectomy compared to group 2. Time and safety parameters did not differ significantly between both groups. The data demonstrate a positive transfer of motor skills between laparoscopic appendectomy and cholecystectomy on the virtual reality simulator; however, the transfer of cognitive skills is limited. Separate training curricula seem to be necessary for each procedure for trainees to practise task-specific cognitive skills effectively. Mentoring could help trainees to get a deeper understanding of the procedures, thereby increasing the chance for the transfer of

Single-incision laparoscopic cholecystectomy for biliary dyskinesia in children: a simple, safe, and inexpensive technique.

To evaluate a low-cost technique for single-incision laparoscopic cholecystectomy (SILC) in children with biliary dyskinesia. Eighteen children with biliary dyskinesia underwent SILC between March and September 2010. Two 5-mm trocars and a directly introduced grasper were inserted through a 2-cm vertical transumbilical incision. Instrument collisions were minimized by using low-profile trocars and a bariatric laparoscope with a right-angle light adaptor. An internally anchored retracting device suspended the gallbladder, obviating the need for an additional trocar. No other special equipment was used. There were 15 girls and 3 boys with a mean age of 15.9 years (range, 9-18 years). Sixteen (88.9%) underwent true SILC. One patient was converted to a four-port laparoscopic procedure because of uncertainty of ductal anatomy. Another required a 5-mm subxiphoid port for liver retraction. Mean operative time was 82 minutes (range, 42-105 minutes): 94 minutes (range, 75-105 minutes) for the first 6 patients, 85 minutes (range, 60-102 minutes) for the second 6, and 68 minutes (range, 42-90 minutes) for the last 6. Operative times between the first and last groups were significantly different (P=.02). Sixteen patients were discharged home the following day and the remaining 2 on the second postoperative day. There were no complications. The hospital costs of the disposable equipment needed to perform SILC at our institution was $205.05 less than that needed for the four-port operation ($516.32 versus $721.37), a 28.4% savings. SILC is safe and feasible in children with biliary dyskinesia. The operative time decreased with experience. The disposable equipment needed was less expensive than that used for the standard laparoscopic technique.

This study compares surgical techniques and surgeon's standing position during laparoscopic cholecystectomy (LC), investigating each with respect to surgeons' learning, performance, and ergonomics. Little homogeneity exists in LC performance and training. Variations in standing position (side-standing technique vs. between-standing technique) and hand technique (one-handed vs. two-handed) exist. Thirty-two LC procedures performed on a virtual reality simulator were video-recorded and analyzed. Each subject performed four different procedures: one-handed/side-standing, one-handed/between-standing, two-handed/side-standing, and two-handed/between-standing. Physical ergonomics were evaluated using Rapid Upper Limb Assessment (RULA). Mental workload assessment was acquired with the National Aeronautics and Space Administration-Task Load Index (NASA-TLX). Virtual reality (VR) simulator-generated performance evaluation and a subjective survey were analyzed. RULA scores were consistently lower (indicating better ergonomics) for the between-standing technique and higher (indicating worse ergonomics) for the side-standing technique, regardless of whether one- or two-handed. Anatomical scores overall showed side-standing to have a detrimental effect on the upper arms and trunk. The NASA-TLX showed significant association between the side-standing position and high physical demand, effort, and frustration (p<0.05). The two-handed technique in the side-standing position required more effort than the one-handed (p<0.05). No difference in operative time or complication rate was demonstrated among the four procedures. The two-handed/between-standing method was chosen as the best procedure to teach and standardize. Laparoscopic cholecystectomy poses a risk of physical injury to the surgeon. As LC is currently commonly performed in the United States, the left side-standing position may lead to increased physical demand and effort, resulting in ergonomically unsound conditions for

This study aimed to compare the efficacy of local anaesthetic infiltration to trocar wounds and intraperitoneally on postoperative pain as a part of a multimodal analgesia method after laparoscopic cholecystectomies. The study was performed on 90 ASA I-III patients aged between 20 and 70 years who underwent elective laparoscopic cholecystectomy. All patients had the same general anaesthesia drug regimen. Patients were randomized into three groups by a closed envelope method: group I (n=30), trocar site local anaesthetic infiltration (20 mL of 0.5% bupivacaine); group II (n=30), intraperitoneal local anaesthetic instillation (20 mL of 0.5%) and group III (n=30), saline infiltration both trocar sites and intraperitoneally. Postoperative i.v. patient controlled analgesia was initiated for 24 h. In total, 4 mg of i.v. ondansetron was administered to all patients. Visual analogue scale (VAS), nausea and vomiting and shoulder pain were evaluated at 1., 2., 4., 8., 12., 24. hours. An i.v. nonsteroidal anti-inflammatory drug (NSAID) (50 mg of dexketoprofen) as a rescue analgesic was given if the VAS was ≥5. There were no statistical significant differences between the clinical and demographic properties among the three groups (p≥0.005). During all periods, VAS in group I was significantly lower than that in groups II and III (p<0.001). Among the groups, although there was no significant difference in nausea and vomiting (p=0.058), there was a significant difference in shoulder pain. Group III (p<0.05) had more frequent shoulder pain than groups I and II. The total morphine consumption was higher in groups II and III (p<0.001 vs p<0.001) than in group I. The requirement for a rescue analgesic was significantly higher in group III (p<0.05). Trocar site local anaesthetic infiltration is more effective for postoperative analgesia, easier to apply and safer than other analgesia methods. Morphine consumption is lesser and side effects are fewer; therefore, this method can be

Following laparoscopic cholecystectomy, an effective post-operative pain control is necessary, at least during the first 24 hours. We present a randomized, double-blind trial on the effect of the combined use of intravenous parecoxib, and metamizol or paracetamol on piritramide consumption using a patient-controlled analgesia (PCA) pump in patients recovering from laparoscopic cholecystectomy. 120 patients were randomly allocated to four patient groups treated with normal saline or one of non-opioid analgesics (parecoxib 40 mg twice daily, metamizol 1 g three times daily, paracetamol 1 g three times daily) in addition to piritramide using the PCA pump. Beginning in the post-anesthesia care unit (PACU), patients were asked every 2 h for 6 hours and afterwards once every 6 h to quantify their pain experience at rest while piritramide consumption was recorded. In all groups, piritramide consumption was high in PACU. Only metamizol significantly reduced piritramide consumption compared to the others upon discharge from PACU. Overall, cumulative piritramide consumption was slightly lower in the metamizol group and higher in the NaCl group; however, these findings were statistically not significant. VAS scores were highest upon arrival in PACU and dropped almost continuously after surgery. A significantly lower postoperative pain intensity was only found in the parecoxib group at 24 h after surgery compared to the metamizol group. The efficacy of tested additive medications on piritramide consumption and pain relief is weak and there is no clear-cut difference between the non-opioid drugs used.

Training programs for resident surgeons represent a challenge for the mentoring activity. The aim of the present study is to investigate the impact of our training program for laparoscopic cholecystectomy on patient's safety and on the modulation of the residents' exposure to clinical scenario with different grades of complexity. This is a retrospective study based on a clinical series of laparoscopic cholecystectomy performed in a teaching hospital. Study population was grouped according to the expertise of the attending primary operator among resident surgeons. Four groups were identified: consultant (C), senior resident (SR); intermediate level resident (IR); junior resident (JR). The intraoperative and postoperative outcomes were confronted to evaluate the patient's safety profile. 447 patients were submitted to LC: 96 cases were operated by a C, 200 by SR, 112 by IR and 39 by JR. The mean operative time was the longest for the JR group. A statistically higher rate of conversion to open approach was registered in C and IR groups in comparison to JR and SR groups. However, in C and IR groups, patients had worse ASA score, higher BMI and more frequent past history of previous abdominal surgery, cholecystitis or pancreatitis. Overall, it was not registered any statistically significant difference among the groups in terms of length of hospital stay and prevalence of major postoperative complications. Applying an educational model based on both graduated levels of responsibility and modulated grade of clinical complexity can guarantee an high safety profile.

Laparoscopic cholecystectomy (LC), one of the most commonly performed surgical procedures, remains associated with significant major morbidity including bile leak and bile duct injury (BDI). The effect of changes in practice over time, and of interventions to improve patient safety, on morbidity rates is not well understood. The aim of this review was to describe current incidence rates and trends for BDI and other complications during and after LC, and to identify risk factors and preventative measures associated with morbidity and BDI. PubMed, MEDLINE, and Web of Science database searches and data extraction were conducted for studies which reported individual complications and complication rates following laparoscopic cholecystectomy in a representative population. Outcomes data were pooled. Meta-regression analysis was performed to assess factors associated with conversion, morbidity, and BDI rates. One hundred and fifty-one studies reporting outcomes for 505,292 patients were included in the final quantitative synthesis. Overall morbidity, BDI, and mortality rates were 1.6-5.3%, 0.32-0.52%, and 0.08-0.14%, respectively. Reported BDI rates reduced over time (1994-1999: 0.69(0.52-0.84)% versus 2010-2015 0.22(0.02-0.40)%, p = 0.011). Meta-regression analysis suggested higher conversion rates in developed versus developing countries (4.7 vs. 3.4%), though a greater degree of reporting bias was present in these studies, with no other significant associations identified. Overall, trends suggest a reduction in BDI over time with unchanged morbidity and mortality rates. However, data and reporting are heterogenous. Establishment of international outcomes registries should be considered.

Natural orifice transluminal endoscopic surgery (NOTES) is a technique still in experimental development whose safety and effectiveness call for assessment through clinical trials. In this paper we present a three-arm, noninferiority, prospective randomized clinical trial of 1 year duration comparing the vaginal and transumbilical approaches for transluminal endoscopic surgery with the conventional laparoscopic approach for elective cholecystectomy. Sixty female patients between the ages of 18 and 65 years who were eligible for elective cholecystectomy were randomized in a ratio of 1:1:1 to receive hybrid transvaginal NOTES (TV group), hybrid transumbilical NOTES (TU group) or conventional laparoscopy (CL group). The main study variable was parietal complications (wound infection, bleeding, and eventration). The analysis was by intention to treat, and losses were not replaced. Cholecystectomy was successfully performed on 94% of the patients. One patient in the TU group was reconverted to CL owing to difficulty in maneuvering the endoscope. After a minimum follow-up period of 1 year, no differences were noted in the rate of parietal complications. Postoperative pain, length of hospital stay, and time off from work were similar in the three groups. No patient developed dyspareunia. Surgical time was longer among cases in which a flexible endoscope was used (CL, 47.04 min; TV, 64.85 min; TU, 59.80 min). NOTES approaches using the flexible endoscope are not inferior in safety or effectiveness to conventional laparoscopy. The transumbilical approach with flexible endoscope is as effective and safe as the transvaginal approach and is a promising, single-incision approach.

The optimal timing of cholecystectomy for patients admitted with acute gallbladder pathology is unclear. Some studies have shown that emergency cholecystectomy during the index admission can reduce length of hospital stay with similar rates of conversion to open surgery, complications and mortality compared with a 'delayed' operation following discharge. Others have reported that cholecystectomy during the index acute admission results in higher morbidity, extended length of stay and increased costs. This study examined the cost-effectiveness of emergency versus delayed cholecystectomy for acute benign gallbladder disease. Using data from a prospective population-based cohort study examining the outcomes of cholecystectomy in the UK and Ireland, a model-based cost-utility analysis was conducted from the perspective of the UK National Health Service, with a 1-year time horizon for costs and outcomes. Probabilistic sensitivity analysis was used to investigate the impact of parameter uncertainty on the results obtained from the model. Emergency cholecystectomy was found to be less costly (£4570 versus £4720; €5484 versus €5664) and more effective (0·8868 versus 0·8662 QALYs) than delayed cholecystectomy. Probabilistic sensitivity analysis showed that the emergency strategy is more than 60 per cent likely to be cost-effective across willingness-to-pay values for the QALY from £0 to £100 000 (€0-120 000). Emergency cholecystectomy is less costly and more effective than delayed cholecystectomy. This approach is likely to be beneficial to patients in terms of improved health outcomes and to the healthcare provider owing to the reduced costs. © 2016 BJS Society Ltd Published by John Wiley & Sons Ltd.

Online videos are among the most common resources for case preparation. Using crowd sourcing, we evaluated the relationship between operative quality and viewing characteristics of online laparoscopic cholecystectomy videos. We edited 160 online videos of laparoscopic cholecystectomy to 60 seconds or less. Crowd workers (CW) rated videos using Global Objective Assessment of Laparoscopic Skills (GOALS), the critical view of safety (CVS) criteria, and assigned overall pass/fail ratings if CVS was achieved; linear mixed effects models derived average ratings. Views, likes, dislikes, subscribers, and country were recorded for subset analysis of YouTube videos. Spearman correlation coefficient (SCC) assessed correlation between performance measures. One video (0.06%) achieved a passing CVS score of ≥5; 23%, ≥4; 44%, ≥3; 79%, ≥2; and 100% ≥1. Pass/fail ratings correlated to CVS, SCC 0.95 (p < 0.001) and to GOALS, SCC 0.79 (p < 0.001). YouTube videos (n = 139) with higher views, likes, or subscribers did not correlate with better quality. The average CVS and GOALS scores were no different for videos with >20,000 views (22%) compared with those with <20,000 (78%). There is an incredibly low frequency of CVS and average GOALS technical performance in frequently used online surgical videos of LC. Favorable characteristics, such as number of views or likes, do not translate to higher quality. Copyright © 2017 American College of Surgeons. Published by Elsevier Inc. All rights reserved.

Surgical procedures are mentally and physically demanding, and stress during surgery may compromise patient safety. We investigated the impact of surgical experience on surgeons' stress levels and how perioperative sleep quality may influence surgical performance. Eight experienced and 8 inexperienced surgeons each performed 1 laparoscopic cholecystectomy. Questionnaires measuring perioperative mental and physical strain using validated visual analog scale and Borg scales were completed. Preoperative and postoperative sleep quality of the surgeon was registered and correlated to perioperative strain parameters. Preoperative to postoperative frustration among experienced surgeons was significantly reduced and this was not found in the inexperienced surgeons (visual analog scale: preoperative 13 (2-65) mm, postoperative 4 (0-51) mm vs. preoperative 5(0-10) mm, postoperative 5(1-46) mm; P=0.04). Physical strain was significantly induced in both groups in the upper extremities. Preoperative and postoperative sleep quality was significantly correlated to postoperative mental strain parameters. Perioperative frustration levels were different among inexperienced and experienced surgeons. Perioperative sleep quality may influence postoperative mental strain and should be considered in studies examining surgeons' stress.

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.

To compare the LMAS with LMAP in terms of ventilatory efficacy, airway leak pressure (airway protection), ease-of-use and complications. Prospective, single-blind, randomised, controlled study. The Hospital del Sureste and Hospital Ramon y Cajal, Madrid, between May 2009 and March 2011. The Hospital del Sureste is a secondary hospital and Hospital Ramon y Cajal is a tertiary hospital. Patients undergoing elective laparoscopic cholecystectomy were studied following informed consent. Inclusion criteria were American Society of Anesthesiologists physical status I to III and age 18 or more. Exclusion criteria were BMI more than 40 kg m, symptomatic hiatus hernia or severe gastro-oesophageal reflux. Anaesthesiologists experienced in the use of LMAP and LMAS participated in the trial. One hundred twenty-two patients were randomly allocated to LMAS or LMAP. Our primary outcome measure was the oropharyngeal leak pressure (OLP). Secondary outcomes were the time and number of attempts for insertion, ease of insertion of the drain tube, adequacy of ventilation and the incidence of complication. Patients were interviewed postoperatively to evaluate the presence of sore throat, dysphagia or dysphonia. Two patients were excluded when surgery changed from laparoscopic to open. A total of 120 patients were finally included in the analysis. The mean OLP in the LMAP group was significantly higher than that in the LMAS group (30.7 ± 6.2 versus 26.8 ± 4.1 cmH2O;P < 0.01). This was consistent with a higher maximum tidal volume achieved with the LMAP compared to the LMAS (511 ± 68 versus 475 ± 55 ml; P = 0.04). The success rate of the first attempt insertion was higher for the LMAS group than the LMAP group (96.7 and 71.2%, respectively; P < 0.01). The time taken for insertion, ease of

Laparoscopic cholecystectomy (LC) for symptomatic gallstone disease is one of the most common surgical procedures. Concomitant common bile duct (CBD) stones are detected with an incidence of 4-20% and the ideal management is still controversial. The frequent practice is to perform endoscopic sphincterotomy pre-operatively (POES) followed by LC, to allow subsequent laparoscopic or open exploration if POES fails. However, POES has shown different drawbacks such as need for two hospital admissions, need of two anesthesia inductions, higher rate of pancreatitis, and longer hospital stay. Hence, an intra-operative endoscopic sphincerotomy (IOES) has been proposed. To compare the 1 stage laparoscopic cholecystectomy (LC) combined with IOES versus 2-stage POES followed by LC for the management of pre-operatively known cholecystocholedocholithiasis. The search terms bile duct stones/calculi, ERCP, endoscopic sphincterotomy, laparoendoscopic rendezvous (LERV), and laparoscopic ductal clearance/choledochotomy/exploration were used. A comprehensive hand-based search of reference lists of published articles and review articles was performed to ensure inclusion of all possible studies and exclude duplicates. RCTs comparing 1 stage LC combined with IOES versus 2-stage POES followed by LC for the management of pre-operatively known cholecystocholedocholithiasis in adults. Three reviewers assessed trial quality and extracted the data. Data were entered in revman version 5.3. The trials were grouped according to the outcome measure assessed such as success rate of CBD stone clearance, incidence of pancreatitis, overall morbidity, and length of hospital stay. A total of 629 patients in 5 RCTs met the inclusion criteria. The success rate of CBD clearance (IOES = 93%, POES = 92%) was the same in both groups (OR 1.34; 95% CI 0.45-0.97; p = 0.60).

AIM: To perform a large-scale retrospective comparison of laparoendoscopic single-site cholecystectomy (LESSC) and three-port laparoscopic cholecystectomy (TPLC) in a single institution. METHODS: Data were collected from 366 patients undergoing LESSC between January 2005 and July 2008 and were compared with the data from 355 patients undergoing TPLC between August 2008 and November 2011 in our department. Patients with body mass index greater than 35 kg/m2, a history of major upper abdominal surgery, signs of acute cholecystitis, such as fever, right upper quadrant tenderness with or without Murphy’s sign, elevated white blood cell count, imaging findings suggestive of pericholecystic fluid, gallbladder wall thickening > 4 mm, and gallstones > 3 cm, were excluded to avoid bias. RESULTS: Altogether, 298 LESSC and 315 TPLC patients met the inclusion criteria. The groups were well matched with regard to demographic data. There were no significant differences in terms of postoperative complications (contusion: 19 vs 25 and hematoma at incision: 11 vs 19), hospital stay (mean ± SD, 1.4 ± 0.2 d vs 1.4 ± 0.7 d) and visual analogue pain score (mean ± SD, 8 h after surgery: 2.3 ± 1.4 vs 2.3 ± 1.3 and at day 1: 1.2 ± 0.4 vs 1.3 ± 1.2) between the LESSC and TPLC patients. Four patients required the addition of extra ports and 2 patients were converted to open surgery in the LESSC group, which was not significantly different when compared with TPLC patients converted to laparotomy (2 vs 2). LESSC resulted in a longer operating time (mean ± SD, 54.8 ± 11.0 min vs 33.5 ± 9.0 min), a higher incidence of intraoperative gallbladder perforation (56 vs 6) and higher operating cost (mean ± SD, 1933.7 ± 64.4 USD vs 1874.7 ± 46.2 USD) than TPLC. No significant differences in operating time (mean ± SD, 34.3 ± 6.0 min vs 32.7 ± 8.7 min) and total cost (mean ± SD, 1881.3 ± 32.8 USD vs 1876.2 ± 33.4 USD) were found when the last 100 cases in the two groups were

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

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

To compare the analgesic efficacy of ultrasound-guided single-shot and continuous transversus abdominis plane (TAP) block to that of IV-PCA in patients undergoing laparoscopic cholecystectomy. Prospective randomized controlled trial. Post-anesthesia care unit and General ward. 108 American Society of Anesthesiologist (ASA) physical status I-II patients undergoing laparoscopic cholecystectomy. Group A received IV-PCA; group B received both ultrasound-guided single-shot TAP block with 0.2% ropivacaine (20mL) and IV-PCA; and group C received continuous TAP block using an ultrasound-guidance-inserted indwelling catheter. In group C, infusion of 0.2% ropivacaine at a basal rate of 3mL/h, bolus dose of 4mL, and a lockout interval of 30min was maintained for 48h postoperatively. The primary outcome was evaluated analgesic efficacy using the numeric rating scale (NRS) for 48h postoperatively. Other outcomes included the number of patients requiring additional analgesics, patient satisfaction with postoperative pain control, and incidence of postoperative adverse events. Compared to other groups, group C had higher deep abdominal NRS at 1h postoperatively (P<0.05), and lower incidence of postoperative urinary retention (P<0.05). There were no significant intergroup differences in the number of patients requiring additional analgesics, and patient satisfaction with postoperative pain control. Compared to IV-PCA with or without single-shot TAP block, ultrasound-guided continuous TAP block provided similar analgesia in somatic pain and less analgesia in visceral pain. Moreover, the latter resulted in a lower incidence of postoperative urinary retention. Copyright © 2017 Elsevier Inc. All rights reserved.

Surgical Innovation and the Multiple Meanings of Randomized Controlled Trials: The First RCT on Minimally Invasive Cholecystectomy (1980–2000)

2017-01-01

Abstract This article uses the case of the first randomized controlled trial (RCT) evaluating laparoscopic cholecystectomy to investigate the introduction of minimally invasive surgery in the 1990s and explore the meaning of RCTs within the context of the introduction of a new surgical technology. It thus brings together the history of the use of laparoscopic cholecystectomy to remove the gallbladder, and the history of the RCT, shedding light on particular aspects of both. We first situate the RCT in the context of the history of the various treatment options for gallstones, or cholelithiasis, then characterize the specific situation of the rapid, patient-driven spread of laparoscopic cholecystectomy, and in a next step describe how the local context of laparoscopic cholecystectomy as a new technology made it possible and desirable to conduct an RCT, despite numerous obstacles. This article then shows that in order to capture and understand the rationale of an RCT it is worth it to explore the various levels and dimensions of its context, demonstrating how even the RCT as an ostensibly universal tool draws its meaning from its contexts and that this meaning goes beyond the simple determination of efficiency and safety, including, maybe most importantly, the control and management of new technologies.

While carbohydrate loading is an important component of enhanced patient recovery after surgery, no study has evaluated the effects of preoperative carbohydrate loading after laparoscopic cholecystectomy (LC) on patient satisfaction and overall recovery. Thus, we aimed to investigate the impact of preoperative oral carbohydrates on scores from the quality of recovery 40-item (QoR-40) questionnaire after LC. A total of 153 adults who underwent LC were randomized into three groups. Group MN-NPO was fasted from midnight until surgery. Group No-NPO received 400 mL of a carbohydrate beverage on the evening before surgery, and a morning dose of 400 mL was ingested at least 2 h before surgery. Group Placebo received the same quantity of flavored water as for group No-NPO. The quality of recovery after general anesthesia was evaluated using QoR-40 questionnaire. Intraoperative hemodynamics were also evaluated. There were no significant differences among the groups in terms of the pre- and postoperative global QoR-40 scores (P = 0.257). Group MN-NPO had an elevated heart rate compared to patients who ingested a preoperative beverage (groups No-NPO and Placebo; P = 0.0412). The preoperative carbohydrate beverage did not improve quality of recovery using the QoR-40 questionnaire after general anesthesia for laparoscopic cholecystectomy compared to placebo or conventional fasting. However, the preoperative fasting group had a consistently increased heart rate during changes in body position that induced hypotension, which is likely a result of depletion of effective intravascular volume caused by traditional fasting over 8 h.

Background Only 2% to 4% of patients with melanoma will be diagnosed with gastrointestinal metastasis during the course of their disease. The most common sites of gastrointestinal metastases from melanoma include the small bowel (35%–67%), colon (9%–15%) and stomach (5%–7%), with a median survival of 6–10 months after surgery, and 18% survival at five years. Metastatic melanoma to the gallbladder is extremely rare and it is associated with a very poor prognosis. Case presentation We report a case of a 54-year old man presented to observation with diagnosis of 6.1 mm thick, Clark's level IV, ulcerated melanoma of the trunk, developing in the course of the disease metastatic involvement of the gallbladder as first site of recurrence, treated by laparoscopic cholecystectomy. To date only few cases of patients with metastatic melanoma of the gallbladder treated by this surgical procedure have been reported in literature. Conclusion Gallbladder metastasis represents a rare event as a first site of recurrence. It must be considered a possible expression of systemic disease also despite radiological absence of other metastatic lesions. Laparoscopic approach has a possible therapeutic role, but open surgery has also a concomitant diagnostic purpose because gives the possibility of manual exploration of abdominal cavity, useful particularly to reveal bowel metastatic lesions, not easily identifiable by preoperative imaging examinations.

The role of percutaneous cholecystostomy (PC) is undefined in patients with multiple comorbidities presenting with emergent calculous cholecystitis (CC). This study compared outcomes between PC, laparoscopic (LC), and open cholecystectomy (OC). The Vizient UHC database was queried for high-risk patients with CC who underwent PC, LC, OC, or laparoscopic converted to open cholecystectomy (CONV). Demographics, outcomes, mortality, length of stay (LOS), and direct cost were compared between the groups. LC was the most common approach with the lowest risk of death, complications, LOS, and cost. Complication risk was highest in OC. Nearly 20% of patients underwent PC. Complication rate, LOS, infection, aspiration pneumonia, and mortality were higher in PC. Direct cost was lowest in LC, followed by CONV, PC, and OC. Emergent cholecystectomy for CC in high-risk patients is safer and more cost effective than PC and this study supports the use of cholecystectomy as the primary treatment approach in these patients.

Greenbaum, Alissa; Parasher, Gulshan; Demarest, Gerald; Auyang, Edward

2017-05-05

Iatrogenic duodenal injury occurring during laparoscopic cholecystectomy (LC) is managed surgically, though rarely a large, persistent fistula is refractory to surgical interventions. We present the case of a 40-year-old woman transferred to our centre following elective LC for a reported perforated duodenal ulcer. An uncontained leak was found to originate from a 1.5 cm duodenal defect, with no evidence of ulceration. A duodenostomy tube was placed. One month after abdominal closure, the patient continued to have a persistent, large duodenal fistula. A through-the-scope covered oesophageal stent was placed under endoscopic and fluoroscopic guidance. Five weeks later, it was successfully retrieved and no subsequent extravasation of contrast from the duodenum was noted. Unrecognised iatrogenic duodenal injuries sustained during LC can be catastrophic. In cases of massive duodenal defects and high-output biliary fistula uncontrolled after surgical intervention, endoscopic-guided and fluoroscopic-guided placement of a fully covered oesophageal stent may be lifesaving. © BMJ Publishing Group Ltd (unless otherwise stated in the text of the article) 2017.

2010-06-01

This study was designed to compare the effects of preoperative and postoperative incentive spirometry on lung functions after laparoscopic cholecystectomy in 50 otherwise normal healthy adults. Patients were randomized into a control group (group PO, n=25) and a study group (group PR, n=25). Patients in group PR were instructed to carry out incentive spirometry before the surgery 15 times, every fourth hourly, for 1 week whereas in group PO, incentive spirometry was carried out during the postoperative period. Lung functions were recorded at the time of preanesthetic evaluation, on the day before the surgery, postoperatively at 6, 24, and 48 hours, and at discharge. Significant improvement in the lung functions was seen after preoperative incentive spirometry (group PR), P<0.05. The lung functions were significantly reduced till the time of discharge in both the groups. However, lung functions were better preserved in group PR at all times when compared with group PO; P<0.05. To conclude, lung functions are better preserved with preoperative than postoperative incentive spirometry.

The study was carried out to analyze the learning rate for laparoscopic skills on a virtual reality training system and to establish whether the simulator was able to differentiate between surgeons with different laparoscopic experience. Forty-one surgeons were divided into three groups according to their experience in laparoscopic surgery: masters (group 1, performed more than 100 cholecystectomies), intermediates (group 2, between 15 and 80 cholecystectomies), and beginners (group 3, fewer than 10 cholecystectomies) were included in the study. The participants were tested on the Minimally Invasive Surgical Trainer-Virtual Reality (MIST-VR) 10 consecutive times within a 1-month period. Assessment of laparoscopic skills included time, errors, and economy of hand movement, measured by the simulator. The learning curves regarding time reached plateau after the second repetition for group 1, the fifth repetition for group 2, and the seventh repetition for group 3 (Friedman's tests P <0.05). Experienced surgeons did not improve their error or economy of movement scores (Friedman's tests, P >0.2) indicating the absence of a learning curve for these parameters. Group 2 error scores reached plateau after the first repetition, and group 3 after the fifth repetition. Group 2 improved their economy of movement score up to the third repetition and group 3 up to the sixth repetition (Friedman's tests, P <0.05). Experienced surgeons (group 1) demonstrated best performance parameters, followed by group 2 and group 3 (Mann-Whitney test P <0.05). Different learning curves existed for surgeons with different laparoscopic background. The familiarization rate on the simulator was proportional to the operative experience of the surgeons. Experienced surgeons demonstrated best laparoscopic performance on the simulator, followed by those with intermediate experience and the beginners. These differences indicate that the scoring system of MIST-VR is sensitive and specific to measuring

Laparoscopic cholecystectomy is the standard of care for cholelithiasis as well as cholecystitis. However, in the setting of Mirizzi syndrome or gangrenous cholecystitis where the critical view cannot be ascertained, subtotal cholecystectomy may be necessary. Using the robot-assisted approach, difficult cholecystectomies can be performed upfront without need for partial cholecystectomy. Even in the setting of Mirizzi syndrome where severe scarring and fibrosis are evident, definitive cholecystectomy and takedown of the cholechystocholedochal fistula can be performed in a safe and feasible fashion following successful endoscopic common bile duct stent placement. The purposes of this report are to review the history of Mirizzi syndrome as well as its traditional and novel treatment techniques and highlight technical pearls of the robotic approach to this diagnosis.

The purpose of this study was to estimate the effects of surgical laparoscopic operation course on laparoscopic operation skills after the simulated training for medical students with relatively objective results via data gained before and after the practice course of laparoscopic simulator of the resident standardized trainees. Experiment 1: 20 resident standardized trainees with no experience in laparoscopic surgery were included in the inexperienced group and finished simulated cholecystectomy according to simulator videos. Simulator data was collected (total operation time, path length, average speed of instrument movement, movement efficiency, number of perforations, the time cautery is applied without appropriate contact with adhesions, number of serious complications). Ten attending doctors were included in the experienced group and conducted the operation of simulated cholecystectomy directly. Data was collected with simulator. Data of two groups was compared. Experiment 2: Participants in inexperienced group were assigned to basic group (receiving 8 items of basic operation training) and special group (receiving 8 items of basic operation training and 4 items of specialized training), and 10 persons for each group. They received training course designed by us respectively. After training level had reached the expected target, simulated cholecystectomy was performed, and data was collected. Experimental data between basic group and special group was compared and then data between special group and experienced group was compared. Results of experiment 1 showed that there is significant difference between data in inexperienced group in which participants operated simulated cholecystectomy only according to instructors' teaching and operation video and data in experienced group. Result of experiment 2 suggested that, total operation time, number of perforations, number of serious complications, number of non-cauterized bleeding and the time cautery is applied

Cholelithiasis is the second cause of hospital admissions in Chile. To study the prevalence of symptomatic gallstone disease and opportunity of cholecystectomy in La Florida, Santiago and among Mapuche Indians in Huapi Island. In the period 2000-2001, we contacted to 71% (1127 subjects) and to 61% (145 subjects) patients of La Florida and Huapi Island, respectively, that had previously participated in an epidemiological study on cholelithiasis in 1993. We defined symptomatic gallstone patients as those with a history of biliary colic. Each patient was subjected to gallbladder ultrasound. In 1993, 30-35% of gallstone patients were symptomatic (approximately 70% women). During the lapse 1993-2001, only 50% of subjects from La Florida and 25% of patients from Huapi Island were cholecystectomized (p < 0.05). Fifty percent of cholecystectomies were emergency operations. In 38 symptomatic Mapuche Indians from Huapi, cholecystectomy was indicated in 2001. After five months of the indication, only one of these subjects had been operated. Laparoscopic cholecystectomy represented 40% of all cholecystectomies performed in the National Health Service Hospitals. This study demonstrates an unacceptable high prevalence of symptomatic gallstone patients remaining non-operated in both the urban and rural communities. This reciprocally correlates with the high frequency of emergency cholecystectomies and the high incidence of gallbladder cancer among Chileans. This study contrasts negatively with the situation of Scotland, where 73.5% of cholecystectomies were laparoscopic in 1998-1999. To reach Scotland standards, the Chilean Public Health System should increase the number of cholecystectomies from 27,000 in 2001 to 57,510

Effects of different levels of end-expiratory pressure on hemodynamic, respiratory mechanics and systemic stress response during laparoscopic cholecystectomy.

General anesthesia causes reduction of functional residual capacity. And this decrease can lead to atelectasis and intrapulmonary shunting in the lung. In this study we want to evaluate the effects of 5 and 10cmH 2 O PEEP levels on gas exchange, hemodynamic, respiratory mechanics and systemic stress response in laparoscopic cholecystectomy. American Society of Anesthesiologist I-II physical status 43 patients scheduled for laparoscopic cholecystectomy were randomly selected to receive external PEEP of 5cmH 2 O (PEEP 5 group) or 10cmH 2 O PEEP (PEEP 10 group) during pneumoperitoneum. Basal hemodynamic parameters were recorded, and arterial blood gases (ABG) and blood sampling were done for cortisol, insulin and glucose level estimations to assess the systemic stress response before induction of anesthesia. Thirty minutes after the pneumoperitoneum, the respiratory and hemodynamic parameters were recorded again and ABG and sampling for cortisol, insulin, and glucose levels were repeated. Lastly hemodynamic parameters were recorded; ABG analysis and sampling for stress response levels were taken after 60minutes from extubation. There were no statistical differences between the two groups about hemodynamic and respiratory parameters except mean airway pressure (P mean ). P mean , compliance and PaO 2 ; pH values were higher in 'PEEP 10 group'. Also, PaCO 2 values were lower in 'PEEP 10 group'. No differences were observed between insulin and lactic acid levels in the two groups. But postoperative cortisol level was significantly lower in 'PEEP 10 group'. Ventilation with 10cmH 2 O PEEP increases compliance and oxygenation, does not cause hemodynamic and respiratory complications and reduces the postoperative stress response.

Concomitant cholelithiasis and choledocholithiasis is a disease where incidence increases with age and can have serious complications such as pancreatitis, cholangitis and liver abscesses, but its management is controversial, because there are minimally invasive laparoscopic and endoscopic surgical procedures. To compare the efficiency in the management of cholelithiasis and choledocholithiasis with laparoscopic cholecystectomy with common bile duct exploration vs cholangiopancreatography endoscopic retrograde+laparoscopic cholecystectomy. Retrospective analysis of a five year observational, cross sectional multicenter study of patients with cholelithiasis and concomitant high risk of choledocholithiasis who were divided into two groups and the efficiency of both procedures was compared. Group 1 underwent laparoscopic cholecystectomy with common bile duct exploration and group 2 underwent cholangiopancreatography endoscopic retrograde+laparoscopic cholecystectomy. 40 patients, 20 were included in each group, we found p=0.10 in terms of operating time; when we compared hospital days we found p=0.63; the success of stone extraction by study group we obtained was p=0.15; the complications presented by group was p=0.1 and the number of hospitalizations by group was p ≤ 0.05 demonstrating statistical significance. Both approaches have the same efficiency in the management of cholelithiasis and choledocholithiasis in terms of operating time, success in extracting stone, days of hospitalization, postoperative complications and conversion to open surgery. However the laparoscopic approach is favourable because it reduces the number of surgical anaesthetic events and the number of hospital admissions. Copyright © 2016 Academia Mexicana de Cirugía A.C.

Objective: We analyzed circulating TNF-α and IL-6 to determine systemic inflammatory responses associated with transvaginal cholecystectomy in a porcine model. Methods: Six female pigs were used for a survival study after transvaginal cholecystectomy (NOTES group) using endoscopic submucosal dissection (ESD) instruments and a single-channel endoscope. Blood was drawn preoperatively and 24 hours and 48 hours postoperatively. Four pigs were used as controls. In addition, laparoscopic cholecystectomy was performed in 2 pigs for laparoscopic control. Results: In all 6 pigs in the NOTES group, no major intraoperative complications occurred. No significant differences were found between control, laparoscopic, and NOTES groups in terms of preoperative IL-6 level (P=0.897) and at 24 hours (P=0.790), and 48 hours postoperatively (P=0.945). Similarly, there was no significant difference in mean preoperative (P=0.349) and mean day 2 postoperative TNF-α levels (P=0.11). But a significant increase in day 1 postoperative TNF-α levels in the laparoscopic group compared with that in the control and NOTES groups was observed (P=0.049). One limitation of our study is that the sample size was relatively small. Conclusion: NOTES is safe in animal models in terms of anatomical and cellular level changes with minimal systemic inflammatory host responses elicited. Further study needs to be carried out in humans before NOTES can be recommended for routine use. PMID:19366533

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.

Background. Although rare, injury to the common bile duct (CBD) during laparoscopic cholecystectomy (LC) can be reduced by better intraoperative visualization of the cystic duct (CD) and CBD. The aim of this study was to establish the efficacy of early visualization of the CD and the added value of CBD identification, using near-infrared (NIR) light and the fluorescent agent indocyanine green (ICG), in patients at increased risk of bile duct injury. Materials and Methods. Patients diagnosed with complicated cholecystitis and scheduled for LC were included. The CBD and CD were visualized with NIR light before and during dissection of the liver hilus and at critical view of safety (CVS). Results. Of the 20 patients originally included, 2 were later excluded due to conversion. In 6 of 18 patients, the CD was visualized early during dissection and prior to imaging with conventional white light. The CBD was additionally visualized with ICG-NIR in 7 of 18 patients. In 1 patient, conversion was prevented due to detection of the CD and CBD with ICG-NIR. Conclusions. Early visualization of the CD or additional identification of the CBD using ICG-NIR in patients with complicated cholecystolithiasis can be helpful in preventing CBD injury. Future studies should attempt to establish the optimal dosage and time frame for ICG administration and bile duct visualization with respect to different gallbladder pathologies. PMID:28178882

Subtotal cholecystectomy (SC) is a procedure that removes portions of the gallbladder when structures of the Calot triangle cannot be safely identified in "difficult gallbladders." To conduct a systematic review and meta-analysis to evaluate current studies and present an evidence-based assessment of the outcomes for the techniques available for SC. A literature search of the PubMed/MEDLINE (1954 to November 2013) and EMBASE (1974 to November 2013) databases was conducted. Search criteria included the words subtotal, partial, insufficient or incomplete, and cholecystectomy. Inclusion criteria were all randomized, nonrandomized, and retrospective studies with data on SC techniques and outcomes. Exclusion criteria were studies that reported data on SC along with other interventions (eg, cholecystostomy) without the possibility to discriminate results specific to SC. This systematic review was performed using the Preferred Reporting Items for Systematic Reviews and Meta-analyses (PRISMA) guidelines. The primary outcome of the study was the occurrence of common bild duct injury. Secondary outcomes included the occurrence of other SC-related morbidities, such as hemorrhage, subhepatic collection, bile leak, retained stones, postoperative endoscopic retrograde cholangiopancreatography, wound infection, reoperation, and mortality. Thirty articles were included. Subtotal cholecystectomy was typically performed using the laparoscopic technique (72.9%), followed by the open (19.0%) and laparoscopic converted to open (8.0%) techniques. The most common indications were severe cholecystitis (72.1%), followed by cholelithiasis in liver cirrhosis and portal hypertension (18.2%) and empyema or perforated gallbladder (6.1%). Morbidity rates were relatively low (postoperative hemorrhage, 0.3%; subhepatic collections, 2.9%; bile duct injury, 0.08%; and retained stones, 3.1%); the rate for bile leaks was higher (18.0%). Reoperations were necessary in 1.8% of the cases; the 30-day

Laparoscopy has become the gold standard technique for appendectomy and cholecystectomy. With the emergence of newer laparoscopic instruments which are roticulating and provide 7 degrees of freedom it is now possible to perform these operations through a single umbilical incision rather than the standard 3-4 incisions and thus lead to more desirable cosmetic results and less postoperative pain. The newer reticulating telescopes provide excellent exposure of the operating field and allow the operations to proceed routinely. Recently, ports [Triports (Olympus surgery)/SILS ports] especially designed for single incision laparoscopic surgery (SILS) have been developed. We herein describe our experience with laparoscopic single port appendectomies and cholecystectomies in children using the Triport. This is a retrospective cohort study of children who underwent single incision laparoscopic surgery between May 2009 and August 2010 at Texas Children's Hospital and Ben Taub General Hospital in Houston Texas by a single surgeon. Charts were reviewed for demographics, type of procedure, operative time, early or late complications, outcome and cosmetic results. Fifty-four patients underwent SILS. A total of 50 appendectomies (early or perforated) and 4 cholecystectomies were performed using this new minimally invasive approach. The average operative time for SILS/LESS appendectomy was 54 min with a range between 25 and 205 min, while operative time for SILS cholecystectomy was 156 min with a range of 75-196 min. Only small percentage (4%) of appendectomies (mostly complicated) were converted to standard laparoscopy, but none were converted to open procedure. All patients were followed up in the clinic after 3-4 weeks. No complications were noted and all patients had excellent cosmetic results. Parents were extremely satisfied with the cosmetic results. SILS/LESS is a safe, minimally invasive approach for appendectomy and cholecystectomy in children. This new approach is

Backgrounds/Aims We investigated patients' clinical and radiological data to determine preoperative factors that predict cholesterol gallbladder (GB) polyps of large size, which can be helpful for decision on further diagnostic tools. Methods In this study, we retrospectively analyzed 126 patients who underwent laparoscopic cholecystectomy for GB polyps >10 mm diagnosed preoperatively by abdominal ultrasonography between February 2002 and February 2016 in Department of Surgery, Sanggye Paik Hospital. Patients were divided into non-cholesterol polyps group and cholesterol polyps group, based on the postoperative pathologic diagnosis. Clinical and radiological data, such as gender, age, body weight, height, body mass index (BMI), laboratory findings, size, number and shape of the polypoid lesions, and presence of the concurrent GB stone were compared between the two groups. Results Of the 126 cases, 73 had cholesterol polyps (57.9%) and 53 cases were non-cholesterol polyps (42.1%). The younger age (<48.5 years), size of polyp <13.25 mm and multiple polyps were independent predictive variables for cholesterol polyps, with odd ratios (OR) of 2.352 (p=0.045), 5.429 (p<0.001) and 0.472 (p<0.001), respectively. Conclusions Age, size and polyp number were used to predict cholesterol GB polyp among polypoid lesions of the gallbladder >10 mm. For cases in which these factors are not applicable, it is strongly recommended to evaluate further diagnostic tools, such as computed tomography, endoscopic ultrasonography and tumor markers.

Injuries to the bile duct during laparoscopic cholecystectomy are often a cause of malpractice litigations. A total of 13 legal verdicts as a result of bile duct injury from 1996 to 2009 were reviewed. Comments on the verdicts and the opinions of expert witnesses were analyzed. Out of 13 claims, 7 were upheld and 6 were rejected. Most expert witnesses from 1996 to 2002 stated that not carrying out a cholangiography and insufficient preparation of the cystic duct constituted a performance below the standard of care expected. Expert witness testimonies from 2004 to 2009, however, regarded injury to the bile duct as predominantly inherent to treatment. With the expansion and acceptance of laparoscopic interventions, changes in the results of malpractice litigation have become evident. In contrast to the phase during establishment of the technology, an injury to the bile duct is nowadays judged predominantly as inherent to treatment.

The present study was conducted to evaluate the usefulness and safety of the nonpowder surgical glove for extraction of the gallbladder in laparoscopic cholecystectomy. The study was carried out in Capital Hospital Islamabad and in a private hospital. The duration of study was from March 2009 to March 2012. This was an observational study carried out in 492 patients who underwent laparoscopic cholecystectomy using the surgical glove for extraction of the gallbladder and compared with the conventional method of gall bladder removal in two hospitals were analyzed. The operative findings, port site infection and co morbid conditions were evaluated. Postoperative wound infection was found in 27 (5.48%) of 492 cases. Umbilical port infection was found in 26 (5.28%) of cases in which gall bladder was removed without endogloves and only one case (0.2%) had infection when gall bladder was removed with the endogloves. Wound infection was more in acute cholecystitis (25.9%) and empyema of Gall Bladder (44.4%). Among the co morbid conditions, diabetes mellitus has got higher frequency of wound infection (44%). The use of the surgical glove for extraction of the gallbladder is safe, cheap, simple and potentially reduces significant morbidity. Its routine use at laparoscopic cholecystectomy is mandatory in all cases.

Serious complications continue to occur in laparoscopic cholecystectomy (LC). The commonly used indicators of surgical difficulty such as the duration of surgery are insufficient because they are surgeon and institution dependent. We aimed to identify appropriate indicators of surgical difficulty during LC. A total of 26 Japanese expert LC surgeons discussed using the nominal group technique (NGT) to generate a list of intraoperative findings that contribute to surgical difficulty. Thereafter, a survey was circulated to 61 experts in Japan, Korea, and Taiwan. The questionnaire addressed LC experience, surgical strategy, and perceptions of 30 intraoperative findings listed by the NGT. The response rate of the survey was 100%. There was a statistically significant difference among nations regarding the duration of surgery and adoption rate of safety measures and recognition of landmarks. The criteria for conversion to an open or subtotal cholecystectomy were at the discretion of each surgeon. In contrast, perceptions of the impact of 30 intraoperative findings on surgical difficulty (categorized by factors related to inflammation and additional findings of the gallbladder and other intra-abdominal factors) were consistent among surgeons. Intraoperative findings are objective and considered to be appropriate indicators of surgical difficulty during LC. © 2016 Japanese Society of Hepato-Biliary-Pancreatic Surgery.

Duodenal Ulcer Induced by Hem-o-Lok clip after Reduced Port Laparoscopic Cholecystectomy.

The patient was a 66-year-old woman who had undergone laparoscopic cholecystectomy (Lap-C) secondary to chronic cholecystitis status post endoscopic choledocholithotomy 13 months previously. During surgery, Hem-o-Lok clips were used to control the cystic duct and the cystic artery. Due to the presence of extensive adhesions of the cystic duct and surrounding tissue, the surgeons had difficulty in debriding the area. Thirteen months after Lap-C, the patient underwent a screening esophagogastroduodenoscopy (EGD), which demonstrated clip appearance at the inferior wall of the first part of the duodenum. In the EGD, duodenal erosions and edema were observed around the clip. We appreciated that endoscopic clip removal would be difficult because of the presence of severe adhesions and inflammation of the duodenal bulb. On clinical examination of the patient, no major abnormalities or physical findings were noted. Therefore, we decided not to attempt to remove the clip. The patient was treated with an oral proton pump inhibitor to prevent extensive duodenal mucosal injury. Two months later, we repeated the EGD, which revealed that the clip was no longer present, and the duodenum was covered with normal mucosa surrounding the scar.

Robotic surgical systems have been used at a rapidly increasing rate in general surgery. Many of these procedures have been performed laparoscopically for years. In a surgical encounter, a significant portion of the total costs is associated with consumable supplies. Our hospital system has invested in a software program that can track the costs of consumable surgical supplies. We sought to determine the differences in cost of consumables with elective laparoscopic and robotic procedures for our health care organization. De-identified procedural cost and equipment utilization data were collected from the Surgical Profitability Compass Procedure Cost Manager System (The Advisory Board Company, Washington, DC) for our health care system for laparoscopic and robotic cholecystectomy, fundoplication, and inguinal hernia between the years 2013 and 2015. Outcomes were length of stay, case duration, and supply cost. Statistical analysis was performed using a t-test for continuous variables, and statistical significance was defined as p < 0.05. The total cost of consumable surgical supplies was significantly greater for all robotic procedures. Length of stay did not differ for fundoplication or cholecystectomy. Length of stay was greater for robotic inguinal hernia repair. Case duration was similar for cholecystectomy (84.3 robotic and 75.5 min laparoscopic, p = 0.08), but significantly longer for robotic fundoplication (197.2 robotic and 162.1 min laparoscopic, p = 0.01) and inguinal hernia repair (124.0 robotic and 84.4 min laparoscopic, p = ≪0.01). We found a significantly increased cost of general surgery procedures for our health care system when cases commonly performed laparoscopically are instead performed robotically. Our analysis is limited by the fact that we only included costs associated with consumable surgical supplies. The initial acquisition cost (over $1 million for robotic surgical system), depreciation, and service contract for the robotic

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.

Laparoscopic cholecystectomy (LC) is the treatment of choice for gallstones, but is associated with increased risk of bile duct injury (BDI bile duct injury). If the BDI is detected during LC can be addressed immediately, if available hepatobiliary surgeon, but the easiest and safest procedure for the general surgeon is placing drains into subhepatic region and the transfer of acute BDI to controlled external biliary fistula (external Biliary fistula EBF). Most BDI is diagnosed when the postoperative period, when there is biliary leak. Therapy is a percutaneous catheter drainage and endoscopic stenting in the bile duct; early repair is not recommended. Repair in the form hepatico-jejunostomy (HJ) should be performed hepatobiliary surgeon at intervals of 46 weeks after it closes EBF. BDI is a frequent cause medico-legal actions and a substantial burden on health care costs. Most BDI can be avoided by adherence to the principles of safe cholecystectomy.

Laparoscopic surgery requires working in a three-dimensional environment with a two-dimensional view. Skills such as depth perception, hand to eye co-ordination and bimanual manipulation are crucial to its efficacy. To compare the efficiency of training in laparoscopic skills on a VR simulator with a traditional box trainer. Twenty medical students were recruited. An initial training session on the relevant anatomy and steps of a laparoscopic cholecystectomy was given. Baseline skills were recorded using a pre-training laparoscopic cholecystectomy on the VR trainer. Parameters measured were: (1) total time taken (mins); (2) number of movements right and left instrument; (3) path length (cms) of right and left instrument was recorded. Ten students trained on a VR simulator, and ten on a box trainer, for three hours each. The box trainer group exercises were based on the Royal College of Surgeons core laparoscopic skills course, and the VR trainer exercises were based on the Simbionix LapMentor basic skills tasks. Following this both groups were reassessed by a laparoscopic cholecystectomy on the VR trainer. Both groups showed improvement in all measured parameters. A student T-test at 95% confidence interval showed no statistically significant difference between the two groups pre and post training. Both the VR and box trainer are effective in the acquisition of laparoscopic skills. Copyright © 2011 Surgical Associates Ltd. Published by Elsevier Ltd. All rights reserved.

Regarding the role of gas entry in abdomen and cardiorespiratory effects, the ability of anesthesiologists would be challenged in laparoscopic surgeries. Considering few studies in this area and the relevance of the subject, this study was performed to compare the arterial oxygen alterations before operation in comparison with after surgery between laparoscopic cholecystectomy and ovarian cystectomy. In this prospective cohort, 70 consecutive women aged from 20 to 60 years who were candidate for laparoscopic cholecystectomy (n = 35) and ovarian cystectomy (n = 35) with reverse (20 degrees) and direct (30 degrees) Trendelenburg positions, respectively, with ASA class I or II were enrolled. After intubation and before operation, for the first time, the arterial blood gas from radial artery in supine position was obtained for laboratory assessment. Then, the second blood sample was collected from radial artery in supine position and sent to the lab to be assessed with the same device after 30 minutes from surgery termination. The measured variables from arterial blood gas were arterial partial pressure of oxygen (PaO 2 ) and Oxygen saturation (SpO 2 ) alterations. Total PaO 2 was higher in the first measurement. The higher values of PaO 2 in cholecystectomy (upward) than in ovarian cystectomy (downward) were not significant in univariate (P = 0.060) and multivariate analysis (P = 0.654). Furthermore, higher values of SpO 2 in cholecystectomy (upward) than in ovarian cystectomy (downward) were not significant in univariate (P = 0.412) and multivariate analysis (P = 0.984). In general, based on the results of this study, the values of PaO 2 in cholecystectomy (upward) were not significantly higher than the values in cystectomy (downward) in laparoscopic surgeries when measured 30 minutes after surgery.

Gallbladder diseases are very common in developed countries. Complicated gallstone disease represents the most frequent of biliary disorders for which surgery is regularly advocated. As regards, cholecystectomy represents a common abdominal surgical intervention; it can be performed as either an elective intervention or emergency surgery, in the case of gangrene, perforation, peritonitis or sepsis. Nowadays, the laparoscopic approach is preferred over open laparotomy. Globally, numerous cholecystectomies are performed daily; however, little evidence exists regarding assessment of post-surgical quality of life (QOL) following these interventions. To assess post-cholecystectomy QOL, in fact, documentation of high quality care has been subject to extended discussions, and the use of patient-reported outcome satisfaction for quality improvement has been advocated for several years. However, there has been little research published regarding QOL outcomes following cholecystectomy; in addition, much of the current literature lacks systematic data on patient-centered outcomes. Then, although several tools have been used to measure QOL after cholecystectomy, difficulty remains in selecting meaningful parameters in order to obtain reproducible data to reflect postoperative QOL. The aim of this study was to review the impact of surgery for gallbladder diseases on QOL. This review includes Medline searches of current literature on QOL following cholecystectomy. Most studies demonstrated that symptomatic patients profited more from surgery than patients receiving an elective intervention. Thus, the gain in QOL depends on the general conditions before surgery, and patients without symptoms profit less or may even have a reduction in QOL.

Introduction of endoscopic invasive procedures in the 70th and 80th years leaded to decrease reoperations on biliary tree. latrogenic injury of the biliary tract have increased in incidence in the first decade with the introduction of laparoscopic cholecystectomy. Athough a number of factors have been identified with a high risk of injury (and number of technical steps have been emphasized to avoid these injury, the incidence of the bile duct injury has reached at least double the rate observed with open cholecystectomy. Most patients that sustained a bile duct injury are recognized in the weeks following laparoscopic cholecystectomy. Careful preoperative preparation should include control of sepsis by draining any bile collections or fistulas and complete cholangiography. Long-term results are best achieved in specialized hepatobiliary centers performing biliary reconstruction with a Roux-Y hepaticojejunostomy. Success rates over 90% have been reported from several centres to date with intermediate follow-up. Introduction of an invasive endoscopy. Very dangerous is injury after endoscopic papilotomy.

Introduction As Laparoscopic Cholecystectomy (LC) is not a totally pain free procedure, with the pain being most intense on the day of surgery and on the following day. Various techniques are available for postoperative pain relief like intraperitoneal instillation of local anaesthetics and rectus sheath block (RSB)which may provide effective pain relief. Aim To compare the efficacy of preemptive administration (initiated before the surgical procedure) of intraperitoneal instillation and rectus sheath block using ropivacaine for postoperative analgesia after laparoscopic cholecystectomy. Materials and Methods A total of 75 selected patients were randomly assigned to three equal groups as Group R, who received bilateral RSB with 0.25 % ropivacaine 15 ml on either side; Group I, who received intraperitoneal instillation of 0.25% ropivacaine 50 ml and Group C (Control group), who received only rescue analgesic on pain. These were compared regarding postoperative analgesia in terms of Visual Analog Scale (0-10 cm), Prince Henry Hospital Pain Score (0-3), time to first dose of rescue analgesic (tramadol), total rescue analgesic consumption in 48 hours, patient satisfaction scores (1-7) and adverse effects. Results The time to first rescue analgesic was significantly longer in Group R (16.16±4.73h) and Group I (7.84±1.34h) as compared to Group C (1.72±0.67h), p<0.001. Mean tramadol consumption in 48h for each patient was significantly less in Group R (148±54.92mg) and Group I (202±33.78mg) as compared to Group C (298±22.73mg) p<0.001. Postoperative pain scores were also significantly less in Group R and Group I as compared to Group C during first 6 hours, p<0.05. The difference in above parameters was also significant between Group R and Group I, p<0.05. Thus order of postoperative analgesia effect was: Group R > Group I > Group C. Rescue analgesic requirement showed a 32.21% reduction in Group I and 50.33% reduction in Group R as compared to Group C. Patient

The reported incidence (0.16-1.5 %) of bile duct injury (BDI) during laparoscopic cholecystectomy (LC) is higher than during open cholecystectomy and has not decreased over time despite increasing experience with the procedure. The "critical view of safety" (CVS) technique may help to prevent BDI when certain criteria are met prior to division of any structures. This study aimed to evaluate the adherence of practicing surgeons to the CVS criteria during LC and the impact of a training intervention on CVS identification. LC procedures of general surgeons were video-recorded. De-identified recordings were reviewed by a blinded observer and rated on a 6-point scale using the previously published CVS criteria. A coaching program was conducted, and participating surgeons were re-assessed in the same manner. The observer assessed ten LC videos, each involving a different surgeon. The CVS was adequately achieved by two surgeons (20 %). The remaining eight surgeons (80 %) did not obtain adequate CVS prior to division of any structures, despite two surgeons dictating that they did; the mean score of this group was 1.75. After training, five participating surgeons (50 %) scored > 4, and the mean increased from 1.75 (baseline) to 3.75 (p < 0.05). The CVS criteria were not routinely used by the majority of participating surgeons. Further, one-fourth of those who claimed to obtain the CVS did so inadequately. All surgeons who participated in training showed improvement during their post-assessment. Our findings suggest that education of practicing surgeons in the application of the CVS during LC can result in increased implementation and quality of the CVS. Pending studies with larger samples, our findings may partly explain the sustained BDI incidence despite increased experience with LC. Our study also supports the value of direct observation of surgical practices and subsequent training for quality improvement.

Patients undergoing general anesthesia for laparoscopic cholecystectomy have a high risk of postoperative nausea and vomiting (PONV) with incidences up to 75%. Ramosetron, a serotonin subtype 3 (5-HT(3)) antagonist, has been shown to be effective as an antiemetic after chemotherapy and surgery. Consensus guidelines recommend a combination of antiemetic therapies in high-risk groups. Until now, no published data have been available on the use of combination oral plus intravenous ramosetron. The goal of this prospective, randomized, double-blind study was to compare the efficacy and tolerability of intravenous, oral, and the combination of oral and intravenous ramosetron for PONV prophylaxis in patients undergoing laparoscopic cholecystectomy. Patients scheduled for laparoscopic cholecystectomy were double-randomly allocated to 1 of 3 groups. Patients were randomly allocated to receive either 0.3 mg of intravenous ramosetron (group A), 0.1 mg of oral ramosetron (group B), or the combination of 0.1 mg of oral ramosetron and 0.3 mg of intravenous ramosetron (group C). All patients received standardized balanced anesthesia with desflurane and remifentanil. Postoperative nausea, retching, vomiting, pain, and adverse effects were assessed at 0 to 2, 2 to 24, and 24 to 48 hours after surgery. A total of 124 Korean patients (67 women, 57 men; age range, 25-65 years) were randomized to 1 of 3 study groups (42 in group A [mean age, 49.8 years], 41 in group B [mean age, 47.4 years], and 41 in group C [mean age, 48.9 years]). No statistical differences were observed among the 3 groups with regard to patient characteristics and information on surgery and anesthesia. During postoperative period 0 to 2 hours, complete response occurred in 31 (74%) patients in group A, 27 (66%) in group B, and 37 (90%) in group C. During the postoperative period of 2 to 24 hours, complete response was observed in 36 (86%), 33 (80%), and 40 (98%) patients in groups A, B, and C, respectively; there

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.

Laparoscopic cholecystectomy is commonly performed, and several factors increase the risk of open conversion, prolonging operating time and hospital stay. Preoperative stratification would improve consent, scheduling and identify appropriate training cases. The aim of this study was to develop a validated risk score for conversion for use in clinical practice. Preoperative patient and disease-related variables were identified from a prospective cholecystectomy database (CholeS) of 8820 patients, divided into main and validation sets. Preoperative predictors of conversion were identified by multivariable binary logistic regression. A risk score was developed and validated using a forward stepwise approach. Some 297 procedures (3.4%) were converted. The risk score was derived from six significant predictors: age (p = 0.005), sex (p < 0.001), indication for surgery (p < 0.001), ASA (p < 0.001), thick-walled gallbladder (p = 0.040) and CBD diameter (p = 0.004). Testing the score on the validation set yielded an AUROC = 0.766 (p < 0.001), and a score >6 identified patients at high risk of conversion (7.1% vs. 1.2%). This validated risk score allows preoperative identification of patients at six-fold increased risk of conversion to open cholecystectomy.

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.

Cholecystectomy was one of the first surgical procedures to be performed with laparoscopy in the 1980s. Currently, two operation setups generally are used to perform a laparoscopic cholecystectomy: the French and the American position. In the French position, the patient lies in the lithotomy position, whereas in the American position, the patient lies supine with the left arm in abduction. To find an ergonomic difference between the two operation setups the movements of the surgeon's vertebral column were analyzed in a crossover study. The posture of the surgeon's vertebral column was recorded intraoperatively using an electromagnetic motion-tracking system with three sensors attached to the head and to the trunk at the levels of Th1 and S1. A three-dimensional posture analysis of the cervical and thoracolumbar spine was performed to evaluate four surgeons removing a gallbladder in the French and American position. The body angles assessed were flexion/extension of the cervical and thoracolumbar spine, axial rotation of the cervical and thoracolumbar spine, lateroflexion of the cervical and thoracolumbar spine, and the orientation of the head in the sagittal plane. For each body angle, the mean, the percentage of operation time within an ergonomic acceptable range, and the relative frequencies were calculated and compared. No statistical difference was observed in the mean body angles or in the percentages of operation time within an acceptable range between the French and the American position. The relative frequencies of the body angles might indicate a trend toward slight thoracolumbar flexion in the French position. In a modern dedicated minimally invasive surgery suite, the body posture of the neck and trunk and the orientation of the head did not differ significantly between the French and American position.

2008-01-01

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

2016-01-01

Background and Objectives: Laparoscopic transcystic common bile duct exploration (LTCBDE) is a complex procedure requiring expertise in laparoscopic and choledochoscopic skills. The purpose of this study was to investigate the safety and feasibility of treating biliary calculi through laparoscopic transcystic exploration of the CBD via an ultrathin choledochoscope combined with dual-frequency laser lithotripsy. Methods: From August 2011 through September 2014, 89 patients at our hospital were treated for cholecystolithiasis with biliary calculi. Patients underwent laparoscopic cholecystectomy and exploration of the CBD via the cystic duct and the choledochoscope instrument channel. A dual-band, dual-pulse laser lithotripsy system was used to destroy the calculi. Two intermittent laser emissions (intensity, 0.12 J; pulse width 1.2 μs; and pulse frequency, 10 Hz) were applied during each contact with the calculi. The stones were washed out by water injection or removed by a stone-retrieval basket. Results: Biliary calculi were removed in 1 treatment in all 89 patients. No biliary tract injury or bile leakage was observed. Follow-up examination with type-B ultrasonography or magnetic resonance cholangiopancreatography 3 months after surgery revealed no instances of retained-calculi–related biliary tract stenosis. Conclusion: The combined use of laparoscopic transcystic CBD exploration by ultrathin choledochoscopy and dual-frequency laser lithotripsy offers an accurate, convenient, safe, effective method of treating biliary calculi.

Laparoscopic bile duct injury: understanding the psychology and heuristics of the error.

PubMed

Dekker, Sidney W A; Hugh, Thomas B

2008-12-01

Bile duct injury is an important unsolved problem of laparoscopic cholecystectomy, occurring with unacceptable frequency even in the hands of experienced surgeons. This suggests that a systemic predisposition to the injury is intrinsic to cholecystectomy and indicates that an analysis of the psychology and heuristics of surgical decision-making in relation to duct identification may be a guide to prevention. Review of published reports on laparoscopic bile duct injury from 1997 to 2007 was carried out. An analysis was also carried out of the circumstances of the injuries in 49 patients who had transection of an extrahepatic bile duct and who were referred for reconstruction or were assessed in a medicolegal context. Special emphasis was placed on identifying the possible psychological aspects of duct misidentification. Review of published work showed an emphasis on the technical aspects of correct identification of the cystic duct, with few papers addressing the heuristics and psychology of surgical decision-making during cholecystectomy. Duct misidentification was the cause of injury in 42 out of the 49 reviewed patients (86%). The injury was not recognized at operation in 70% and delay in recognition persisted into the postoperative period in 57%. Underestimation of risk, cue ambiguity and visual misperception ('seeing what you believe') were important factors in misidentification. Delay in recognition of the injury is a feature consistent with cognitive fixation and plan continuation, which help construct and sustain the duct misidentification during the operation and beyond. Changing the 'culture' of cholecystectomy is probably the most effective strategy for preventing laparoscopic bile duct injury, especially if combined with new technical approaches and an understanding of the heuristics and psychology of the duct misidentification error. Training of surgeons for laparoscopic cholecystectomy should emphasize the need to be alert for cues that the incorrect

2014-01-01

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

The learning curve of laparoscopic holecystectomy in general surgery resident training: old age of the patient may be a risk factor?

A well-designed learning curve is essential for the acquisition of laparoscopic skills: but, are there risk factors that can derail the surgical method? From a review of the current literature on the learning curve in laparoscopic surgery, we identified learning curve components in video laparoscopic cholecystectomy; we suggest a learning curve model that can be applied to assess the progress of general surgical residents as they learn and master the stages of video laparoscopic cholecystectomy regardless of type of patient. Electronic databases were interrogated to better define the terms "surgeon", "specialized surgeon", and "specialist surgeon"; we surveyed the literature on surgical residency programs outside Italy to identify learning curve components, influential factors, the importance of tutoring, and the role of reference centers in residency education in surgery. From the definition of acceptable error, self-efficacy, and error classification, we devised a learning curve model that may be applied to training surgical residents in video laparoscopic cholecystectomy. Based on the criteria culled from the literature, the three surgeon categories (general, specialized, and specialist) are distinguished by years of experience, case volume, and error rate; the patients were distinguished for years and characteristics. The training model was constructed as a series of key learning steps in video laparoscopic cholecystectomy. Potential errors were identified and the difficulty of each step was graded using operation-specific characteristics. On completion of each procedure, error checklist scores on procedure-specific performance are tallied to track the learning curve and obtain performance indices of measurement that chart the trainee's progress. The concept of the learning curve in general surgery is disputed. The use of learning steps may enable the resident surgical trainee to acquire video laparoscopic cholecystectomy skills proportional to the instructor

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

Unclosed fascial defect: is it the risk to develop port-site hernia after laparoscopic cholecystectomy?

PubMed

Tangjaroen, Somard; Watanapa, Prasit

2014-02-01

Port-site hernia (PSH) is one of the complications after laparoscopic cholecystectomy (LC). Closure of the fascial defect has been mentioned to prevent such complication. However, the results are still controversial. The present study was done to clarify whether unclosed fascial defect was actually the risk factor for the development of PSH MATERIAL AND METHOD: Two hundred ninety four patients underwent LC by a single surgeon at Kalasin Hospital between 2007 and 2010. The procedure was done by using a four-port technique without closure of any fascial defects. The male:female ratio was 85:209, and the mean body mass index was 24.38 +/- 3.33 (SD). The mean operative time was 18.71 +/- 3.76 minutes and there was no postoperative wound infection. Patients were regularly followed-up and underwent both supine and upright physical examination. The mean duration of follow-up period was 4.94 +/- 1.31 years with the shortest follow-up period of two years. None of the patients in the present study developed PSH in any port sites during the follow-up period. Unclosed fascial defect may not have the significant risk factor of developing PSH after LC.

With the expanding implementation of minimally invasive surgery, the operating team is confronted with challenges in the field of ergonomics. Visual feedback is derived from a monitor placed outside the operating field. This crossover trial was conducted to evaluate and compare neck posture in relation to monitor position in a dedicated minimally invasive surgery (MIS) suite and a conventional operating room. Assessment of the neck was conducted for 16 surgeons, assisting surgeons, and scrub nurses performing a laparoscopic cholecystectomy in both types of operating room. Flexion and rotation of the cervical spine were measured intraoperatively using a video analysis system. A two-question visual analog scale (VAS) questionnaire was used to evaluate posture in relation to the monitor position. Neck rotation was significantly reduced in the MIS suite for the surgeon (p = 0.018) and the assisting surgeon (p < 0.001). Neck flexion was significantly improved in the MIS suite for the surgeon (p < 0.001) and the scrub nurse (p = 0.018). On the questionnaire, the operating room team scored their posture significantly higher in the MIS suite and also indicated fewer musculoskeletal complaints. The ergonomic quality of the neck posture is significantly improved in the MIS suite for the entire operating room team.

A late unusual complication after an open cholecystectomy: Amputation neuroma of the CBD causing obstructive jaundice.

Cholecystectomy is one of the most frequently done procedures in general surgery. There are few reports of amputation neuromas following this procedure. This presentation describes a case of obstructive jaundice due to amputation neuroma in a patient with a history of cholecystectomy. We report about a 53 y o lady who presented with obstructive jaundice, 8 years following open cholecystectomy. Paraclinical investigations were in favor of cholangicarcinoma, however the final pathology revealed an amputation neuroma of the CBD. Amputation neuromas are rarely seen in the era of laparoscopic cholecystectomy. They are benign reparative lesions of the CBD following surgery or manipulation of the extra hepatic biliary tree. It is very difficult to diagnose them pre-operatively. Surgical resection is the first choice of treatment. Traumatic neuromas should always be among the differential diagnosis, when assessing a CBD mass in patients with a previous history of open cholecystectomy or surgery to the gastrointestinal tract.

Ketorolac is a parenterally active nonsteroidal anti-inflammatory drug with localized anti-inflammatory properties. We examine the postoperative analgesic efficacy of locally administered intraperitoneal (IP) ketorolac compared with intravenous (IV) ketorolac during laparoscopic cholecystectomy. With institutional ethics approval, 120 patients undergoing elective laparoscopic cholecystectomy were randomized to receive intraoperative 1) IP ketorolac 30 mg + intravenous saline (IP group), 2) intraperitoneal saline + IV ketorolac 30 mg (IV group), or 3) intraperitoneal saline + intravenous saline (Control group) under standardized anesthesia. The primary and secondary outcomes were postoperative fentanyl requirements in the postanesthesia care unit and the time to first analgesic request, respectively. Other outcomes examined included abdominal pain (at rest and with coughing), shoulder pain, nausea, vomiting, and any other postoperative complications. On average, patients receiving IP ketorolac required less (mean difference, 29 μg; 95% confidence interval [CI], 2 to 56; P = 0.04) fentanyl than patients in the Control group but a similar (mean difference, 16 μg; 95% CI, 12 to 43; P = 0.27) amount compared to patients in the IV group. There was an increase in the median (interquartile range [IQR]) time to first request in the IP group (43[30-52] min) compared with the Control group (35 [27-49]min; P = 0.04) but no difference between the IP group compared with the IV group (47 [40-75] min; P = 0.22). Shoulder pain and resting pain were reduced with IP and IV ketorolac compared with Control, but there was no difference between the IP and IV groups. No differences were observed in any other outcomes, side effects, or complications attributable to opioids or ketorolac at any time points. This study did not demonstrate any advantage for the off-label topical intraperitoneal administration of ketorolac in this surgical population. Intraperitoneal and IV ketorolac showed

Surgical approach is still controversial in patients with acute cholecystitis: to treat clinically the inflammatory process and operate electively later or to operate immediately on an emergency basis? To test the hypothesis that urgent laparoscopic cholecystectomy in acute cholecystitis has a higher mortality than elective laparoscopic cholecystectomy. From the data available in Datasus, mortality was compared between patients undergoing elective laparoscopic cholecystectomy for cholelithiasis and in urgency. Calculations were made of the relative reduction in risk of death, absolute reduction of risk of death and number needed to treat. From 2009 to 2014 in Brazil, there were 250.439 laparoscopic cholecystectomy and 74.6% were electives. Mortality in the emergency group was 4.8 times higher compared to the elective group (0.0023% vs. 0.00048%). Despite the relative reduction in risk of death (RRR) was 83%, in the calculation of absolute risk was found 0.0018 and number needed to treat of 55,555. Despite the relative risk reduction for mortality was high comparing elective vs. urgent basis, the absolute risk reduction was minimal, since this outcome is very low in both groups, suggesting that mortality should not have much influence on surgical decision.

Background Payers and regulatory bodies are increasingly placing emphasis on cost containment, quality/outcome measurement and transparent reporting. Significant cost variation occurs in many operative procedures without a clear relationship with outcomes. Clear cost-benefit associations will be necessary to justify expenditures in the era of bundled payment structures. Methods All laparoscopic cholecystectomies (LCCKs) performed within a single health system over a 1-year period were analysed for operating room (OR) supply cost. The cost was correlated with American College of Surgeons National Surgical Quality Improvement Program (ACS NSQIP) outcomes. Results From July 2013 to June 2014, 2178 LCCKs were performed by 55 surgeons at seven hospitals. The median case OR supply cost was $513 ± 156. There was variation in cost between individual surgeons and within an individual surgeon's practice. There was no correlation between cost and ACS NSQIP outcomes. The majority of cost variation was explained by selection of trocar and clip applier constructs. Conclusions Significant case OR cost variation is present in LCCK across a single health system, and there is no clear association between increased cost and NSQIP outcomes. Placed within the larger context of overall cost, the opportunity exists for improved resource utilization with no obvious risk for a reduction in the quality of care. PMID:26345351

Therapeutic advances: Single incision laparoscopic hepatopancreatobiliary surgery

Chang, Stephen Kin Yong; Lee, Kai Yin

2014-01-01

Single-port laparoscopic surgery (SPLS) is proposed to be a step towards minimizing the invasiveness of surgery, and has since gained popularity in several surgical sub-specialties including hepatopancreatobiliary surgery. SPLS has since been applied to cholecystectomy, liver resection as well as pancreatectomy for a multitude of pathologies. Benefits of SPLS over conventional multi-incision laparoscopic surgery include improved cosmesis and potentially post-operative pain at specific time periods and extra-umbilical sites. However, it is also associated with longer operating time, increased rate of complications, and increased rate of port-site hernia. There is no significant difference between length of hospital stay. SPLS has a significant learning curve that affects operating time, rate of conversion and rate of complications. In this article, we review the literature on SPLS in hepatobiliary surgery - cholecystectomy, hepatectomy and pancreatectomy, and offer tips on overcoming potential technical obstacles and minimizing the complications when performing SPLS - surgeon position, position of port and instruments, instrument crossing position, standard hand grip vs reverse hand grip, snooker cue guide position, prevention of incisional hernia. SPLS is a promising direction in laparoscopic surgery, and we recommend step-wise progression of applications of SPLS to various hepatopancreatobiliary surgeries to ensure safe adoption of the surgical technique.

The ability to accurately predict operative duration has the potential to optimise theatre efficiency and utilisation, thus reducing costs and increasing staff and patient satisfaction. With laparoscopic cholecystectomy being one of the most commonly performed procedures worldwide, a tool to predict operative duration could be extremely beneficial to healthcare organisations. Data collected from the CholeS study on patients undergoing cholecystectomy in UK and Irish hospitals between 04/2014 and 05/2014 were used to study operative duration. A multivariable binary logistic regression model was produced in order to identify significant independent predictors of long (> 90 min) operations. The resulting model was converted to a risk score, which was subsequently validated on second cohort of patients using ROC curves. After exclusions, data were available for 7227 patients in the derivation (CholeS) cohort. The median operative duration was 60 min (interquartile range 45-85), with 17.7% of operations lasting longer than 90 min. Ten factors were found to be significant independent predictors of operative durations > 90 min, including ASA, age, previous surgical admissions, BMI, gallbladder wall thickness and CBD diameter. A risk score was then produced from these factors, and applied to a cohort of 2405 patients from a tertiary centre for external validation. This returned an area under the ROC curve of 0.708 (SE = 0.013, p < 0.001), with the proportions of operations lasting > 90 min increasing more than eightfold from 5.1 to 41.8% in the extremes of the score. The scoring tool produced in this study was found to be significantly predictive of long operative durations on validation in an external cohort. As such, the tool may have the potential to enable organisations to better organise theatre lists and deliver greater efficiencies in care.

Background and Aim: Therapeutic use of nonopioid analgesic such as paracetamol (PCM) is an alternative to opioids, so to avoid the established side effects associated with opioids, PCM is commonly used due to its analgesic and antipyretic effects. Recently, dexmedetomidine has also emerged on the anesthesia front with a potential role of providing postoperative analgesia. The present study was conducted to compare and assess the quality and duration of analgesia with PCM and dexmedetomidine using visual analog scale (VAS). Methods: One hundred patients between the age of 18 and 60 years of the American Society of Anesthesiologists grade I and II undergoing laparoscopic cholecystectomy surgery were randomly allocated into two groups (n = 50). Each patient received either 1 g intravenous PCM, in 100 ml solution before incision (Group I), or i.v. dexmedetomidine 1 μg/kg as bolus over 10 min followed by infusion of 0.5 μg/kg/h (Group II). Postoperatively, the following parameters were observed: quality and duration of analgesia, hemodynamic parameters, time to the first dose of rescue analgesia, sedation, and any postoperative complication or side effects. Statistical analysis was carried out using an unpaired t-test for quantitative parameters and nonparametric data using Wilcoxon signed-rank test and Mann–Whitney U-test. Qualitative data were analyzed using Chi-square or Fishers' exact test. Results: Postoperative analgesic requirement significantly decreased (P = 0.001), with a lower score on VAS, better patient satisfaction scores, and Ramsay Sedation Score ranges from 3 to 5 (62%) in Group I. The incidence of nausea and vomiting, hypotension, and bradycardia was comparable in both the groups except shivering, which was found significantly less in Group II. Conclusion: Incorporation of dexmedetomidine as a part of multimodal analgesia provides better hemodynamic profile, analgesic, sedative, and amnesic properties along with negligible serious adverse effects

The emerging role for robotics in cholecystectomy: the dawn of a new era?

Though laparoscopic cholecystectomy (LC) was highly criticized in its early stages, it quickly grew to become a new standard of care and has revolutionized the field of general surgery. Now emerging robotic technology is making its way into the minimally invasive arena. Robotic cholecystectomy (RC) is often disparaged as a costly technology that can lead to increased operative times with outcomes that are quite similar to LC. However, this perspective is skewed as many existing studies were performed in the early phase of learning for this procedure. RC can be performed in a cost-effective manner as the volume of robotic procedures increases. In addition, improved visualization and capability to perform fluorescence cholangiography can improve the safety profile of cholecystectomy to a level that has not yet been achieved with conventional laparoscopy. Advanced simulation technology for robotic surgery, and newer single-site robotic platforms have the potential to further revolutionize this technology and lead to improved patient satisfaction. In this review, we will present current data, trends, and controversies in robotic-assisted cholecystectomy. PMID:29531940

Some scientific studies, with controversial results, have evaluated the efficacy in reducing pain of some different local anesthetic molecules, which were administered at different dosages and in different ways. The primary goal of this randomized, controlled, prospective study (Clinical Trials.gov ID NCT00599144) was to assess the effectiveness of 0.5% bupivacaine for pain control after video-laparoscopic cholecystectomy at its optimal dosage of 2 mg/kg infiltrated in the muscular fasciae of the trocars, or positioned in the gallbladder soaking a sheet of regenerated oxidized cellulose (Tabotamp). A total of 45 patients underwent elective video-laparoscopic cholecystectomy. They were randomized in three groups each made of 15 patients: group A (bupivacaine-soaked Tabotamp positioned in the gallbladder bed), group B (bupivacaine infiltrated in the muscular fasciae of the trocars' seat), group C (control group, not using local anesthetic). Six and twenty-four hours after the intervention, the nature of the pain and its intensity were recorded with the use of a Visual Analogue Scale (VAS). Six hours after the intervention, VAS average was 29.6 +/- 10.92 for group A, 25.86 +/- 16.06 for group B, and 36.13 +/- 16.62 for group C. At 24 h, we recorded 19.26 +/- 15.81, 18.53 +/- 12.3, and 20.46 +/- 20.08 for groups A, B, and C, respectively (p > 0.05). Comparing groups A and B between them and with the control group at 6 and 24 h, we deduced how only the first group showed a statistically significant advantage (p < 0.05) in reducing visceral and shoulder pain compared with the two other groups. Wound infiltration resulted in being statistically favorable in reducing parietal pain only when compared with Group A. For groups A and B, bupivacaine significantly reduced the use of postoperative pain killers. Bupivacaine, either infiltrated in trocars' wounds or kept soaked in a regenerated oxidized cellulose sheet positioned in the gallbladder bed, although safe and not

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.

During single-incision laparoscopic cholecystectomy (SILC), the gallbladder is suspended with stitches, resulting in perforation risk and difficulty in exploration. We used the needle grasper in SILC to hang and manipulate the gallbladder. Sixty-five patients (43 female, 22 male) who underwent SILC between December 2013 and December 2014 were analyzed retrospectively for patient demographics, duration of operation, laparotomy or conventional laparoscopy necessity, drain use, complications, and hospital stay periods. To place the SILC port (Covidien, Inc.), the needle grasper was inserted at the right upper abdominal quadrant without an incision to hang and manipulate the gall-bladder. The mean age was 47.9 ±13.068 years; the mean body mass index (BMI) was 26.94 ±3.913 kg/m 2 . ASA scores were 1, 2, and 3. Two patients with high BMI with additional trocar use were excluded. The operations were completed without any additional trocar in 59 patients. The mean operation time was 89 ±22.41 min. Eighteen patients required a drain; all were discharged after drain removal. One patient needed re-hospitalization and percutaneous drainage and was discharged on the 9 th day. Fifty-three patients were discharged on the 1 st post-operative day. Eleven patients with drains were discharged on the 2 nd day, and 1 was discharged on the 7 th day. The mean hospital stay period was 1.26 ±0.815 days. The main difficulty of SILC is to manipulate hand tools because the triangulation principle of laparoscopy use is not possible in SILC. Inserting a needle grasper into the abdominal cavity at the right subcostal area to manipulate the gallbladder helps and does not leave a visible scar.

To evaluate a newly developed cholecystectomy technique which combines classical dissection with currently available mini-instrumentation (3 and 5 mm) and removal of the gallbladder through a short gastrotomy. After a feasibility study, we set up a protocol for this procedure using instrumentation currently available on the market. The resected gallbladder was removed through a short gastrotomy on the anterior gastric wall, thereby minimizing abdominal wall trauma and permitting the patient to resume physical activity more quickly with no risk of trocar herniation. Cholecystectomy was performed by the described technique in 18 of 23 eligible patients between April 2008 and August 2008. There were seven males and 11 females with a mean age of 48 (range: 28-77); median BMI was 30 kg/m2 (range: 22-36). Eleven patients had a gallstone larger than 12 mm. There were no postoperative complications and recovery was rapid for all patients in our study. This procedure is technically feasible, safe and reproducible; results are good with minimal trauma to the abdominal wall. Normal physical activity can be rapidly resumed with no risk of incisional hernia.

It has become increasingly important to expose surgical residents to robotic surgery as its applications continue to expand. Single-site robotic cholecystectomy (SSRC) is an excellent introductory case to robotics. Resident involvement in SSRC is known to be feasible. Here, we sought to determine whether it is safe to introduce SSRC to junior residents. A total of 98 SSRC cases were performed by general surgery residents between August 2015 and August 2016. Cases were divided into groups based on resident level: second- and third-years (juniors) versus fourth- and fifth-years (seniors). Patient age, gender, race, body mass index, and comorbidities were recorded. The number of prior laparoscopic cholecystectomies completed by participating residents was noted. Outcomes including operative time, console time, rate of conversion to open cholecystectomy, and complication rate were compared between groups. Juniors performed 54 SSRC cases, whereas seniors performed 44. There were no significant differences in patient age, gender, race, body mass index, or comorbidities between the two groups. Juniors had less experience with laparoscopic cholecystectomy. There was no significant difference in mean operative time (92.7 min versus 98.0 min, P = 0.254), console time (48.7 min versus 50.8 min, P = 0.639), or complication rate (3.7% versus 2.3%, P = 0.68) between juniors and seniors. SSRC is an excellent way to introduce general surgery residents to robotics. This study shows that with attending supervision, SSRC is feasible and safe for both junior and senior residents with very low complication rates and no adverse effect on operative time.

2010-01-01

Background: Cystic duct leakage after cholecystectomy is not uncommon and is a potentially serious complication. The aim of this study was to assess a bipolar sealing system (LigaSure®) for closure of the cystic duct. Methods: The records from consecutive laparoscopic cholecystectomies performed in 2 hospitals with closure of the cystic duct with LigaSure after informed consent were recorded and complications and morbidity registered. The records were compared with those of patients undergoing laparoscopic cholecystectomy with closure of the cystic duct with clips during the same period. Results: During the study period, 218 laparoscopic cholecystectomies were performed; 102 of these were performed with the LigaSure. One patient was excluded due to violation of the protocol. We experienced no cases of cystic duct leakage, but in one patient, bile leakage from the gallbladder bed was observed probably due to a small aberrant duct. Conclusion: The LigaSure system was safe and effective for closure and division of the cystic duct in laparoscopic cholecystectomy. PMID:20412641

Morgagni-Larrey hernia (MH) is an unusual diaphragmatic hernia of the retrosternal region. Few cases of MH, treated laparoscopically, associated with Down's syndrome (DS) have been reported in literature. On October 2004, a DS 40-year-old male was admitted to our Department with mild abdominal pain and nausea. Hematochemical tests were within the normal range. Ultrasonography showed biliary sludge and multiple gallstones. Chest X-ray revealed a right-sided paracardiac mass that appeared as MH after a thoraco-abdominal computed tomography (CT). Four trocars were placed as a routinary cholecystectomy. Abdominal exploration confirmed the presence of a voluminous hernia through a wide diaphragmatic defect (12 cm) on the left side of the falciform ligament, containing the last 20 cm ileal loops and right colon with the third lateral of transverse. After retrograde cholecystectomy and reduction of the herniated ileo-colonic tract from multiple adherences, the defect was repaired with an interrupted 2/0 silk suture and then a running 2/0 polypropylene suture. Postoperative course was complicated by pulmonary edema but subsequently the patient was discharged without further complications and has no recurrence after 2 years. In conclusion, surgery is necessary for symptomatic MH and to prevent possible severe complications. We preferred laparoscopy for the reduced morbidity compared to laparotomy, even if in our case the postoperative course was not uneventful. There are still few comparative data about the modality of closure of the defect between primary repair with nonabsorbable suture material, in case of small defects, or continuous monofilament suture or prosthesis in case of large defects.

Data on the quality of communication during informed consent for surgery is sparse; we investigated this issue in a cohort of patients undergoing laparoscopic cholecystectomy (LC). Two hundred and seven consecutive patients with benign biliary disease who had undergone LC completed 2 questionnaires. We investigated the patient choice to undergo the surgical procedure along with perceptions of risk complications presented by the surgeon. Nineteen attending surgeons also completed a questionnaire giving information on their recall perception on the information they provided. Multiple logistic regression analyses determined the predictors of perceived communication factors during the informed consent process. One hundred eighty-one patients (87.4%) returned questionnaires. Younger patients (<50 y) with lower education perceived higher level of risk complications compared with older and higher educated patients (P=0.04 and P<0.001). Younger patients felt psychologic support was necessary (P<0.001) and that quality of life issues related to the interventions were under addressed (P=0.018). Differences were observed between patients' recalled risk of complications and the risk to convert LC to open laparotomy and physicians' perception of information provided to patients regarding these aspects (P<0.01). Although informed consent for surgical procedures requires that the procedures are explained and that the patient understands the procedures and risks, our data suggest different perceptions of the quality of information provided during this process between patients and physicians. Physicians should be aware that surgical risks might be perceived differently by patients and this perception might be influenced, for example, by patients' age and education. Major efforts should be directed to improve communications skills in surgical laparoscopy.

From September 1992 through February 1993 27 randomly chosen female patients were evaluated for differences in postoperative pain intensity (as determined by visual-analogue-scale (VAS)) and analgesic requirements via patient-controlled-analgesia (PCA), either after open lower-abdominal-laparotomy (n = 16, group 1) or after minimal-invasive-cholecystectomy (n = 11, group 2). The type of anaesthesia has been standardized, either as balanced or total intravenous anaesthesia. There were no statistically significant differences between the groups regarding to age, height, weight, intraoperative anaesthetic drug consumption, or duration of anaesthesia and surgery (205.6 vs 185.5 minutes; 139.1 vs 105.0 minutes). All patients could be extubated while still in the operation theatre. The 10-hour study period started after transfer to the recovery room. Heart- and respiratory-rate, systolic/diastolic blood pressure, endtidal pCO2, oxygen-saturation via pulsoxymetry (SaO2), and demands from PCA-pump were recorded, furthermore pain scores were determined every hour. The VAS-scores showed no significant differences between the two groups. The pain level as a whole was low, with the scores ranging from a maximum of 23.4 mm (group 1 after the first hour) to a minimum of 1.8 min (group 2 after 5, 8 an 10 hours). The overall analgesic requirements differed significantly (37.7 vs 17.3 mg piritramid, p < .01). There was a difference throughout the whole study period, although statistically significant only at the 1., 2. (p < .05), 5. and 6.-8. hour (p < .01). This study showed that pain scores were similar after laparoscopic upper or open lower abdominal surgery, both requiring adequate analgesic therapy.(ABSTRACT TRUNCATED AT 250 WORDS)

In some cases, laparoscopic cholecystectomy (LC) may be difficult to perform in patients with acute cholecystitis (AC) with severe inflammation and fibrosis. The Tokyo Guidelines 2018 (TG18) expand the indications for LC under difficult conditions for each level of severity of AC. As a result of expanding the indications for LC to treat AC, it is absolutely necessary to avoid any increase in bile duct injury (BDI), particularly vasculo-biliary injury (VBI), which is known to occur at a certain rate in LC. Since the Tokyo Guidelines 2013 (TG13), an attempt has been made to assess intraoperative findings as objective indicators of surgical difficulty; based on expert consensus on these difficulty indicators, bail-out procedures (including conversion to open cholecystectomy) have been indicated for cases in which LC for AC is difficult to perform. A bail-out procedure should be chosen if, when the Calot's triangle is appropriately retracted and used as a landmark, a critical view of safety (CVS) cannot be achieved because of the presence of nondissectable scarring or severe fibrosis. We propose standardized safe steps for LC to treat AC. To achieve a CVS, it is vital to dissect at a location above (on the ventral side of) the imaginary line connecting the base of the left medial section (Segment 4) and the roof of Rouvière's sulcus and to fulfill the three criteria of CVS before dividing any structures. Achieving a CVS prevents the misidentification of the cystic duct and the common bile duct, which are most commonly confused.

To develop an evidence-based virtual reality laparoscopic training curriculum for novice laparoscopic surgeons to achieve a proficient level of skill prior to participating in live cases. Technical skills for laparoscopic surgery must be acquired within a competency-based curriculum that begins in the surgical skills laboratory. Implementation of this program necessitates the definition of the validity, learning curves and proficiency criteria on the training tool. The study recruited 40 surgeons, classified into experienced (performed >100 laparoscopic cholecystectomies) or novice groups (<10 laparoscopic cholecystectomies). Ten novices and 10 experienced surgeons were tested on basic tasks, and 11 novices and 9 experienced surgeons on a procedural module for dissection of Calot triangle. Performance of the 2 groups was assessed using time, error, and economy of movement parameters. All basic tasks demonstrated construct validity (Mann-Whitney U test, P < 0.05), and learning curves for novices plateaued at a median of 7 repetitions (Friedman's test, P < 0.05). Expert surgeons demonstrated a learning rate at a median of 2 repetitions (P < 0.05). Performance on the dissection module demonstrated significant differences between experts and novices (P < 0.002); learning curves for novice subjects plateaued at the fourth repetition (P < 0.05). Expert benchmark criteria were defined for validated parameters on each task. A competency-based training curriculum for novice laparoscopic surgeons has been defined. This can serve to ensure that junior trainees have acquired prerequisite levels of skill prior to entering the operating room, and put them directly into practice.

Most gallbladder carcinoma cases are suspected pre-operatively or intra-operatively. In Malaysia histopathological examination of cholecystectomy specimens has become routine practice. The aim of this study was to assess the impact of routine histological examinations on cholecystectomy specimens from an Asian demographic, which may differ from a Caucasian demographic. A retrospective study was performed of all histopathology reports for cholecystectomies (laparoscopic and open) undertaken over a period of 12 years (1997-2008) in a single teaching hospital. A total of 1,375 gallbladder specimens were sent for histopathological analysis, with 7 (0.5%) being reported as malignant while only three (0.2%) were found to contain primary gallbladder carcinoma. Other premalignant findings included two specimens with dysplastic changes of the mucosa and one tubulovillous adenoma with a dysplastic epithelium. From the ten malignant and premalignant specimens, seven were diagnosed pre-operatively, two were suspected intra-operatively and one was diagnosed with dysplastic changes on the histopathology report post-operatively. This study supports earlier research carried out in the UK and the demographic difference does not affect the impact of the histology examination on cholecystectomy specimens in diagnosing this disease. A selective policy is recommended in Malaysia.

Laparoscopic cholecystectomy (LC) has become the standard procedure, and contributes to a shorter hospital stay. However, there have been no reports regarding when the patients can be discharged in terms of their health-related quality of life (HRQOL). The HRQOL was evaluated by using the SF-8 health survey (SF-8) 24-hour version in 127 consecutive patients treated from May 2007 to December 2008. The HRQOL and a visual analogue scale (VAS) score were assessed on the day before surgery and on postoperative day (POD) 1, POD2 and POD7. All scores of the eight domains on POD1 were significantly decreased compared to the preoperative score (P < 0.05), and seven scores were still decreased on POD2, with the mental health (MH) domain showing an improvement. On POD7, the general health score improved to the preoperative level. The physical component summary 8 (PCS-8) was suppressed for all 7 days after LC. The mental health component summary 8 (MCS-8) was improved to the preoperative level on POD2, despite the significant suppression observed on POD1 (P < 0.05). The VAS score was higher in the low PCS-8 (PCS-8 < 42.4) and low MCS-8 (MCS-8 < 40.6) patients than in the high PCS-8 and high MCS-8 patients. The HRQOL score demonstrated the improvement of the MCS-8 on POD2, which might suggest that a discharge of LC patients is appropriate on POD2 in terms of the patients' point of view.

During laparoscopic cholecystectomy, the removal of the gall bladder, pyrolysis occurs in the peritoneal cavity. Chemical substances which are formed during this process escape into the operating room through trocars in the form of surgical smoke. The aim of this study was to identify and quantitatively measure a number of selected chemical substances found in surgical smoke and to assess the risk they carry to medical personnel. The study was performed at the Maria Skłodowska-Curie Memorial Provincial Specialist Hospital in Zgierz between 2011 and 2013. Air samples were collected in the operating room during laparoscopic cholecystectomy. A complete qualitative and quantitative analysis of the air samples showed a number of chemical substances present, such as aldehydes, benzene, toluene, ethylbenzene, xylene, ozone, dioxins and others. The concentrations of these substances were much lower than the hygienic standards allowed by the European Union Maximum Acceptable Concentration (MAC). The calculated risk of developing cancer as a result of exposure to surgical smoke during laparoscopic cholecystectomy is negligible. Yet it should be kept in mind that repeated exposure to a cocktail of these substances increases the possibility of developing adverse effects. Many of these compounds are toxic, and may possibly be carcinogenic, mutagenic or genotoxic. Therefore, it is necessary to remove surgical smoke from the operating room in order to protect medical personnel.

We previously identified 25 intraoperative findings during laparoscopic cholecystectomy (LC) as potential indicators of surgical difficulty per nominal group technique. This study aimed to build a consensus among expert LC surgeons on the impact of each item on surgical difficulty. Surgeons from Japan, Korea, and Taiwan (n = 554) participated in a Delphi process and graded the 25 items on a seven-stage scale (range, 0-6). Consensus was defined as (1) the interquartile range (IQR) of overall responses ≤2 and (2) ≥66% of the responses concentrated within a median ± 1 after stratification by workplace and LC experience level. Response rates for the first and the second-round Delphi were 92.6% and 90.3%, respectively. Final consensus was reached for all the 25 items. 'Diffuse scarring in the Calot's triangle area' in the 'Factors related to inflammation of the gallbladder' category had the strongest impact on surgical difficulty (median, 5; IQR, 1). Surgeons agreed that the surgical difficulty increases as more fibrotic change and scarring develop. The median point for each item was set as the difficulty score.

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

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

Laparoscopic cholecystectomy (LC) actually represents the most used and proper treatment for gallbladder lithiasis, because its many and known advantages in comparison with 'open' abdominal surgery. But there are some problems during and after LC due to the use of the electric scalpel and these have brought to the search of an alternative system of dissection and coagulation. The ultrasonically activated scalpel (Harmonic Scalpel, HS) allows to perform dissection and coagulation with a minimal thermal side effect for surrounding tissues, unlike the electrocoagulation. Furthermore, the use of the HS brings a series of advantages in comparison to the other electromagnetic forms of energy (electro-scalpel, laser). HS cuts and coagulates with the same effectiveness of the electro-scalpel but, unlike this, it doesn't introduce risks of wandering currents. Moreover, HS contributes to have a more clean and clear (smokes-free) field of operation and it reduces the operative time, the bleeding and the costs of the operation without an increase of the complications and of the percentages of 'open' conversion, and perhaps leads to a less negative influence on the postoperative systemic immune response. The Authors report their experience that confirm these observations, according also with results reported in a brief review of the recent scientific literature, and support wider diffusion and technical development of this ultrasonically-operating surgical team.

Healthcare cost modeling have favored early (ELC) over interval laparoscopic cholecystectomy (ILC) for acute cholecystitis (AC). However, actual costs of treatment have never been studied. The aim of the present study was to compare actual hospital costs involved in ELC and ILC in patients with AC. Retrospective study of patients who underwent laparoscopic cholecystectomy for AC was conducted. Demographic, clinical, operative data and costs were extracted and analyzed. Between 2011 and 2013, 201 had laparoscopic surgery for AC at Tan Tock Seng Hospital, Singapore. One hundred and thirty-four (67%) patients underwent ELC (≤7 days of presentation, within index admission). Median total length of stay (LOS) was 4.6 and 6.8 days for ELC and ILC groups, respectively (P = 0.006). Patients who had ELC also had significantly lesser total number of admissions (P < 0.001). The median (IQR) total inpatient costs were €4.4 × 10(3) (3.6-5.6) and €5.5 × 10(3) (4.0-7.5) for ELC and ILC patients, respectively (P < 0.007). Costs associated with investigations were significantly higher in the ILC group (P = 0.039), of which serological costs made most difference (P < 0.005). The ward costs were also significantly higher in the ILC group. The cost differences reflect the significantly increased total LOS, and repeat presentations associated with ILC. Therefore, ELC should be the preferred management strategy for AC. © 2014 Japanese Society of Hepato-Biliary-Pancreatic Surgery.

Occasionally patients awaiting heart or lung transplant because of terminal disease require other types of surgery, but present significant challenges to the anaesthetist because of impaired organ function. Regional anaesthesia may have much to offer such patients and we here report one who underwent successfully a laparoscopic cholecystectomy under segmental subarachnoid (spinal) anaesthesia performed at the low thoracic level. The anatomical and physiological consequences of such a technique are discussed.

Generally, surgeons' perceptions of surgical safety are based on experience and institutional policy. Our recent pilot survey demonstrated that the acceptable duration of surgery and criteria for open conversion during laparoscopic cholecystectomy (LC) vary among workplaces. A web-based survey was distributed to 554 expert LC surgeons in Japan, Korea, and Taiwan. The questionnaire covered LC experience, safety measures and recognition of landmarks, decision-making regarding conversion to open/partial cholecystectomy and the implications of this decision. Overall responses were compared among nations, and then stratified by LC experience level (lifetime cases 200-499, 500-999, and ≥1,000). The response rate was 92.6% (513/554); 67 surgeons with ≤199 LCs were excluded, and responses from 446 surgeons were analyzed. We observed significant differences among nations on almost all questions. Differences that remained after stratification by LC experience were on questions related to acceptable duration of surgery, adoption rates of intraoperative cholangiography, the "critical view of safety" technique, identification of Rouvière's sulcus, recognition of the SS-Inner layer theory, and intraoperative judgment to abandon conventional LC. Even among experts, surgeons' perceptions during LC are workplace-dependent. A novel grading system of surgical difficulty and standardized LC procedures are paramount to generate high-level evidence. © 2016 Japanese Society of Hepato-Biliary-Pancreatic Surgery.

A simple technique of laparoscopic port closure allowing wound extension.

PubMed

Christey, G R; Poole, G

2002-04-01

Reliable and safe access to the abdominal cavity and efficient removal of the resected gallbladder are essential to laparoscopic cholecystectomy. The unpredictable size of the cholecystectomy specimen can sometimes lead to frustration at the time of removal. A simple technique has been developed that allows for tissue extraction and easy fascial closure regardless of the size of the specimen. This is achieved by using a four bite "U-shaped" purse string at the time of Hasson insertion, with cephalad advancement of the proximal two bites. This allows for variable wound extension and secure closure, without the need for additional sutures.

The main purpose of the study was to test whether the combination of gabapentin (600 mg 4 hours before surgery, 600 mg after 24 hours), ketamine (0.3 mg/kg before anesthesia), lornoxicam (8 mg before anesthesia and 8 mg/12 hours), and local ropivacaine (5 mL 7.5% at insertion sites) provides superior analgesia to each of these drugs alone in the first 24 hours after laparoscopic cholecystectomy. The secondary purpose was to examine whether this combination has less opioid-related side effects. This was a 2-center randomized placebo-controlled trial. One hundred forty-eight patients, between 18 and 70 years of age, were randomly assigned to 6 groups (28 in each group) with the use of computer software: A(gabapentin/ketamine/lornoxicam/ropivacaine); B(gabapentin/placebo/placebo/placebo); C (placebo/ketamine/placebo/placebo); D (placebo/placebo/lornoxicam/placebo); E (placebo/placebo/placebo/ropivacaine); and F (placebo/placebo/placebo/placebo). Only the principal investigator was aware of patients' allocation and provided drugs and placebo in covered prefilled syringes. The primary outcome of the study was the 24-hour morphine consumption. Secondary outcomes were frequency of opioid-related side effects (nausea, vomiting, sedation, pruritus, and dysuria). Only groups A (6.4 mg), B (9.46 mg), and D (9.36 mg) had lower morphine consumption than control group (20.29 mg) (P < 0.001, P = 0.01, and P = 0.008, respectively). Group A was not different from B and D (P = 0.92, P = 0.93). The only difference was in episodes of nausea between groups A (n = 5) and the control group (n = 12) (P = 0.018). The combination of gabapentin, ketamine, lornoxicam, and local ropivacaine does not provide superior analgesia than gabapentin alone or lornoxicam alone after laparoscopic cholecystectomy. The combination reduces only the frequency of postoperative nausea, but larger studies are needed for safer results. © 2014 World Institute of Pain.

Aim of this study is the evaluation of the impact of preoperative informative session using a Multimedia Health Educational Program (MHEP) on patients undergoing elective Laparoscopic Cholecystectomy (LC) for cholelithiasis, preoperative anxiety and postoperative pain and nausea. Sixty consecutive patients scheduled for elective LC were considered for enrollment in the trial. Patients were assigned randomly to four groups: Group A included 15 patients, preoperatively informed regarding LC through the MHEP presented by a Registered Nurse (RN). Group B included 15 patients preoperatively informed through a leaflet (designed and developed using the exact contents of the MHEP). In Group C, there were 15 patients who were being informed verbally from the RN. Finally, the control Group D included 15 patients, who had the conventional preoperative information about the operation and postoperative course by the attending surgeon and anesthesiologist, as every other patient included in groups A, B, C. Preoperative assessment of patient's knowledge about cholelithiasis and LC was performed after informative session, and was based on a specifically developed "closed, true-false" questionnaire. Preliminary results suggest that conventional information provided by the attending surgeon (Group D) is inadequate. Specifically developed informative sessions with the contribution of MHEP seems to be effective on reducing preoperative anxiety and postoperative pain, in patients undergoing elective LC.

Twenty-eight surgeons, members of the Société Française de Chirurgie Endoscopique et de Radiologie Opératoire, took part in this multicenter study, carried out between March 1989 and January 1991. Nine hundred and thirty-seven patients were entered into the study, 934 of whom presented with biliary lithiasis and 3 with gallbladder polyps. Biliary colic was found in 918 (98 percent) of patients. One hundred and twenty-five patients (13.3 percent) presented with acute cholecystitis. Laparoscopic cholecystectomy had to be converted to traditional laparotomy in 50 cases (5.3 percent). The most frequent causes of conversion were the presence of cholecystitis (34 percent) and the occurrence of hemorrhage which could not be controlled laparoscopically (18 percent). There was one death (mortality rate: 0.1 percent) and there were 37 postoperative complications (morbidity rate: 3.9 percent) which required reoperation in 11 instances: 4 laparatomies, 5 laparoscopies and 2 ultrasonography guided drainages. The mean duration of postoperative hospital stay for patients without complications or conversion was 3.8 days. These results show both the limits and the advantages of laparoscopic cholecystectomy. This new technique is now well established and should be added to other therapies used in the treatment of patients with biliary lithiasis.

Intraperitoneal local anesthetics have been shown to improve postoperative pain after laparoscopic cholecystectomy (LC). However, the choice of local anesthetic agent is debatable. We compared the analgesic efficacy of intraperitoneal lignocaine (lidocaine) versus bupivacaine after elective LC. We conducted a double-blind, randomized, controlled trial. We randomized consecutive patients undergoing LC into two groups. Group L received 10 mL 2% lignocaine (lidocaine), whereas Group B received 10 mL 0.5% bupivacaine, each diluted in 10 mL normal saline. All patients underwent standard perioperative anesthesia and analgesia protocol. We assessed patients at 0, 4, 8, 12, and 24 h postoperatively for pain using the visual analogue scale and verbal rating scale, and the need for additional analgesic medications. We analyzed a total of 206 patients: 106 in Group L and 100 in Group B. Demographic details were similar between groups (P > 0.05). Abdominal pain decreased significantly with time in both groups, with a similar mean response profile (P < 0.001). There was no statistically significant difference between groups with regard to abdominal or shoulder pain by both visual analogue scale and verbal rating scale at all five time intervals (P > 0.05). There was also no significant difference in the side effect profile of both drugs (P > 0.05). A lower proportion of patients in Group B required additional narcotic analgesia (87%) compared with Group L (94%). This difference was marginally significant (P = 0.057). Bupivacaine and lignocaine (lidocaine) are both safe and equally effective at decreasing postoperative pain after LC. Copyright © 2012 Elsevier Inc. All rights reserved.

Only 2% to 4% of patients with melanoma will be diagnosed with gastrointestinal metastasis during the course of their disease. The most common sites of gastrointestinal metastases from melanoma include the small bowel (35%-67%), colon (9%-15%) and stomach (5%-7%), with a median survival of 6-10 months after surgery, and 18% survival at five years. Metastatic melanoma to the gallbladder is extremely rare and it is associated with a very poor prognosis. We report a case of a 54-year old man presented to observation with diagnosis of 6.1 mm thick, Clark's level IV, ulcerated melanoma of the trunk, developing in the course of the disease metastatic involvement of the gallbladder as first site of recurrence, treated by laparoscopic cholecystectomy. To date only few cases of patients with metastatic melanoma of the gallbladder treated by this surgical procedure have been reported in literature. Gallbladder metastasis represents a rare event as a first site of recurrence. It must be considered a possible expression of systemic disease also despite radiological absence of other metastatic lesions. Laparoscopic approach has a possible therapeutic role, but open surgery has also a concomitant diagnostic purpose because gives the possibility of manual exploration of abdominal cavity, useful particularly to reveal bowel metastatic lesions, not easily identifiable by preoperative imaging examinations.

Aim of this study is the evaluation of the impact of a multimedia CD (MCD) on preoperative anxiety and postoperative recovery of patients undergoing elective laparoscopic cholecystectomy (LC). Sixty consecutive candidates for elective LC were randomly assigned to four groups. Group A included 15 patients preoperatively informed regarding LC through the MCD presented by Registered Nurse (RN). Patients in group B (n = 15) were informed through a leaflet. Patients in group C (n = 15) were informed verbally from a RN. Finally, the control Group D included 15 patients informed conventionally by the attending surgeon and anesthesiologist, as every other patient included in groups A, B, and C. Preoperative assessment of knowledge about LC was performed after each informative session through a questionnaire. Evaluation of preoperative anxiety was conducted using APAIS scale. Postoperative pain and nausea scores were measured using an NRS scale, 16 hours after the patient had returned to the ward. Statistical processing of the results (single linear regression) showed that patients in groups A, B, and C achieved a higher knowledge score, less preoperative anxiety score and less postoperative pain and nausea, compared to Group D. In multiple regression analysis, group A had a higher knowledge score compared to the four groups (p < 0.001 r(2) = 0.41). Informative sessions using MCD is an effective means of improving patient's preoperative knowledge, especially in day-surgery cases, like LC.

Even though laparoscopic cholecystectomy (LC) emerged over 20 years ago, controversies persist with regard to the best method to ligate the cystic duct and artery. We proposed to assess the effectiveness and safety of electrocoagulation to seal the cystic artery and cystic duct after their occlusion with only one absorbable clip. We retrospectively compared the clinical data for 635 patients undergoing LC using electrocoagulation to seal the cystic artery and cystic duct that were occluded with only one absorbable clip (Group 1) and 728 patients undergoing LC using titanium clips (Group 2). In parallel, 30 rabbits randomized into six groups underwent cholecystectomy. After cystic duct ligation with absorbable or titanium clips, the animals were sacrificed 1, 3, or 6 months later, and intraabdominal adhesions were assessed after celiotomy. The mean operative time was significantly shorter (41.6 versus 58.9 minutes, P<.01) in Group 1 than in Group 2. No cystic duct leaks occurred in any patients from Group 1, compared with seven leaks among the 728 (0.96%) patients from Group 2 (P<.05). The morbidity was significantly higher in Group 2 than in Group 1 (3.43% versus 1.58%). Mean intraoperative blood loss and hospitalization length were not significantly different between the two groups, and no deaths occurred in either group. In animal experiments, adhesion was tighter for absorbable than for titanium clips, but fibrous tissue encapsulation was thinner at the site of titanium clips. Electrocoagulation of the cystic artery and cystic duct that were occluded with only one absorbable clip is safe and effective during LC. This approach is associated with shortened operative times and reduced leakage, compared with the standard method using metal clips.

The outcome evaluated were infeccious complications at surgical site. The patients were reviewed seven and 30 days after surgery. There was incidence of 2% in infection complications in group A and 2% in group B. There was no statistical significant difference of infectious complications (p=0,05) between the groups. The groups were homogeneous and comparable. The use of the antibiotic prophylaxis in laparoscopic cholecystectomy in low risk patients doesn't provide any significant benefit in the decrease of surgical wound infection.

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.

Laparoscopic cholecystectomy (LC) has been the gold standard for surgical treatment of gallbladder disease since 1980. This laparoscopic surgical procedure is one of the first to be performed by general surgery residents. There is a learning curve required to excel at performing LC. During this period, the operation needs to be performed under the supervision of a senior surgeon. The purpose of this study was to compare LC performed by residents with that performed by senior surgeons using the following parameters: operative time, conversion rate, complication rate, and mean length of hospital stay. This retrospective study included 1219 patients who underwent elective LC in our institute-788 operated on by a senior surgeon and 431 by a resident. The mean operative time was 39 ± 19 minutes. There was a significant difference between the groups, as the mean operative time for the resident group was 49.9 ± 13 compared with 33.7 ± 6 for the senior surgeon group. The overall conversion rate was 2.1%, the complication rate was 2.2%, and the mean length of hospital stay was 1.5 days. There were no statistically significant differences between the groups for these parameters. The only significant difference between the groups was a longer operative time, as the conversion rate, complication rate, and mean length of stay were the same. Therefore, it is safe for LC to be performed by residents supervised by a senior surgeon. Copyright © 2015. Published by Elsevier Inc.

Laparoscopic cholecystectomy has undergone an explosive growth. Its benefits to patients--shortened recovery time and less pain--became immediately obvious. The procedure's development and adaptation have largely been devised and implemented by ingenious and creative private practitioners, not the typical mode of introduction. Most or many new procedures in the past evolved from academic institutions after laboratory and then clinical trials. With rapid development and acceptance has come an additional new burden among medical practitioners: credentialing and granting clinical privileges.

The ideal management of common bile duct (CBD) stones remains controversial, whether with single-stage management using laparoscopic CBD exploration (LCBDE) during laparoscopic cholecystectomy, or with 2-stage management using preoperative or postoperative ERCP. We wished to elucidate the practice patterns within our health system, which includes both large urban referral centers and small rural critical access hospitals. We conducted a retrospective data analysis from our 22-hospital, not-for-profit, integrated healthcare system. All patients with a diagnosis of choledocholithiasis who underwent laparoscopic cholecystectomy (LC) and either ERCP or LCBDE for duct clearance between 2008 and 2013 were included. Demographic data, along with disease-specific characteristics and outcomes, were collected and compared. During the study period, 37,301 patients underwent LC. Of these, 1,961 (5.3%) met inclusion criteria. Single-stage management with LC+LCBDE was performed in 28% of patients, and the remaining 72% underwent 2-stage management with ERCP (73% postoperative ERCP, 27% preoperative). Mean total number of procedures was lowest in the LC+LCBDE group vs the post-cholecystectomy ERCP group vs the preoperative ERCP group (mean 1.4 vs 2.1 vs 2.3; p < 0.05). Hospital charges were also lower in the LC+LCBDE group vs post-cholecystectomy ERCP vs preoperative ERCP groups ($9,000 vs $10,800 vs $14,200; p < 0.05). Single-stage vs two-stage management varied greatly between hospitals (from 0% to 93%). Single-stage management of CBD stones resulted in the fewest procedures and lower hospital charges without an increase in complications. Single-stage management (LC+LCBDE) of CBD stones is underused and can offer better value in today's cost-constrained environment. Copyright © 2018 American College of Surgeons.

Introduction Cholecystocolic fistula is a rare complication of gallbladder disease. Its clinical presentation is variable and nonspecific, and the diagnosis is made, mostly, incidentally during intraoperative maneuver. Cholecystectomy with closure of the fistula is considered the treatment of choice for the condition, with an increasingly reproducible tendency to the use of laparoscopy. Aim To describe the laparoscopic approach for cholecystocolic fistula and ratify its feasibility even with the unavailability of more specific instruments. Technique After dissection of the communication and section of the gallbladder fundus, the fistula is externalized by an appropriate trocar and sutured manually. Colonic segment is reintroduced into the cavity and cholecystectomy is performed avoiding the conversion procedure to open surgery. Conclusion Laparoscopy for resolution of cholecystocolic fistula isn't only feasible, but also offers a shorter stay at hospital and a milder postoperative period when compared to laparotomy.

The unprecedented rapid and successful adoption of laparoscopic cholecystectomy has prompted the evaluation of converting other standard open surgical procedures to a laparoscopic technique. A wide variety of laparoscopic acid reduction procedures have been successfully accomplished by groups in this country and abroad. Our group reviewed the literature on the many types of open peptic ulcer operations, as well as the ones performed laparoscopically. We elected to perfect the technique of posterior truncal vagotomy and anterior seromyotomy (PTVAS). After extensive animal laboratory work, we performed PTVAS on four patients with documented recurrent peptic ulcer disease. We describe our technique as it evolved and in particular note the usefulness of endoscopic esophageal transillumination. In addition, we report our results and discuss their implications.
