Laparoscopic resection of rectal cancer or gastric cancer has been advocated for the benefits of a reduced morbidity, a shorter treatment time, and similar outcomes. However, simultaneous laparoscopy-assisted low anterior resection and distal gastrectomy for synchronous carcinoma of rectum and stomach are rarely documented in literature. Endoscopic examination revealed a synchronous carcinoma of rectum and stomach in a 55-year-old male patient with rectal bleeding and epigastric discomfort. He underwent a simultaneous laparoscopy-assisted low anterior resection and distal gastrectomy with regional lymph nodes dissected. The operation time was 270 min and the estimated blood loss was 120 mL. The patient required parenteral analgesia for less than 24 h. Flatus was passed on postoperative day 3, and a solid diet was resumed on postoperative day 7. He was discharged on postoperative day 13. With the advances in laparoscopic technology and experience, simultaneous resection is an attractive alternative to a synchronous gastrointestinal cancer. PMID:18528944

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

Laparoscopic radical gastrectomy for gastric cancer has been widely applied in clinical practice, and its indications have been extended from early gastric cancer to advanced gastric cancer. It is acknowledged that laparoscopic radical gastrectomy is technically challenging because of the complexity of anatomy, rich blood supply, and extensive lymph node dissection. This paper primarily intends to share the experience of laparoscopic radical D2 gastrectomy for distal gastric cancer with details of choosing the location of Trocar, surgical approaches and the sequence of lymph node dissection. All the surgeries were performed at Department of General Surgery and Gastrointestinal Surgery, Guangdong General Hospital. The finding suggests that a correct laparoscopic Trocar placement is the foundation of adequate surgical field visualization. Under most circumstances, the observation hole should be around 2 cm below the umbilicus and the operating hole should be close to the bilateral clavicle midline. Furthermore, proper surgical approach and sequence of lymph node dissection are the prerequisites for successful laparoscopic radical D2 gastrectomy, as well as the reassurance of dissecting lymph node safely and comprehensively. The position of surgical team adopted in our center is that the surgeon stands to the left of the patient, with laparoscope operator stands in between patient's legs while the first assistant positions himself opposite the surgeon on the right side of the patient. This position correlates to the rules of sequential lymph node dissection, which is "from left to right", "from proximal to distal" and "from inferior to superior". Therefore, it is conductive to inferior and superior pylorus region dissection and it can effectively prevent subsidiary-injury. In our center, the procedure of lymph node dissection has been standardized: the initial step is to undergo station 4sb dissection and greater gastric curvature clearance; then change the patient

The optimal extent of gastrectomy for middle-third gastric cancer remains controversial. In our study, the short-term effects and longer-term survival outcomes of distal subtotal gastrectomy and total gastrectomy are analysed to determine the optimal extent of gastrectomy for middle-third gastric cancer. We retrospectively collect and analyse clinicopathologic data and follow-up outcomes from a prospectively collected database at the Peking University Cancer Hospital. Patients with middle-third gastric adenocarcinoma who underwent curative resection are enrolled in our study. We collect data of 339 patients between January 2005 and October 2011. A total of 144 patients underwent distal subtotal gastrectomy, and 195 patients underwent total gastrectomy. Patients in the total gastrectomy group have longer operative duration (P < 0.001) and postoperative hospital stay (P = 0.001) than those in the distal subtotal gastrectomy group. In the total gastrectomy group, more lymph nodes are harvested (P < 0.001). Meanwhile, the rate of postoperative complications is lower in the distal subtotal gastrectomy group than in the total gastrectomy group (8% vs 15%, P = 0.047). Further analysis demonstrates that the rate of anastomosis leakage is lower in the distal subtotal gastrectomy group than in the total gastrectomy group (0% vs 4%, P = 0.023). Kaplan-Meier (log rank test) analysis shows a significant difference in overall survival between the two groups. The 5-year overall survival rates in the distal subtotal gastrectomy and total gastrectomy groups are 65% and 47%, respectively (P < 0.001). Further stage-stratified analysis reveals that no statistical significance exists in 5-year survival rate between the distal subtotal gastrectomy and total gastrectomy groups at the same stage. Multivariate analysis shows that age (P = 0.046), operation duration (P < 0.001), complications (P = 0.037), usage of neoadjuvant chemotherapy (P < 0.001), tumor size (P = 0

Background and Objectives: Recent studies have supported minimally invasive techniques as a viable alternative to open surgery in the treatment of gastric cancer. The goal of this study is to review our institution's experience with totally laparoscopic gastrectomy for the treatment of both early- and advanced-stage gastric cancer. Methods: A retrospective study was conducted to examine the short-term outcomes of laparoscopic gastrectomy performed at Monmouth Medical Center between May 2003 and June 2012. We reviewed postoperative complications, surgical margins, number of resected lymph nodes, estimated blood loss, length of stay, narcotic use, and recurrence rate. Results: Forty patients were included in the study. There were 21 cases of adenocarcinoma, 15 cases of gastrointestinal stromal tumor, 2 cases of carcinoid, 1 case of small cell neuroendocrine tumor, and 1 case of squamous cell carcinoma. The mean operative time was 220 minutes (range, 67–450 minutes). The median length of stay was 6 days (range, 1–37 days). The mean number of harvested lymph nodes was 11. Early postoperative complications occurred in 7 patients and included anastomotic stricture, wound infection, intra-abdominal abscess, bowel obstruction, and esophageal pneumatosis. There were two deaths. The Kaplan-Meier 5-year overall and recurrence-free survival rate for all cases of adenocarcinoma was 63.2%. Conclusions: Totally laparoscopic gastrectomy is a reasonable option for the treatment of gastric malignancy, with early data showing acceptable survival rates and perioperative outcomes. Large-scale randomized trials are still needed to confirm oncologic equivalency to open gastrectomy in patients with advanced disease. PMID:24398204

Background Minimally invasive surgery, including laparoscopic and robotic gastrectomy, has become more popular in the treatment of gastric cancer. However, few studies have compared the learning curves between laparoscopic and robotic gastrectomy for gastric cancer. Methods Data were prospectively collected between July 2008 and Aug 2014. A total of 145 patients underwent minimally invasive gastrectomy for gastric cancer by a single surgeon, including 73 laparoscopic and 72 robotic gastrectomies. The clinicopathologic characteristics, operative outcomes and learning curves were compared between the two groups. Results Compared with the laparoscopic group, the robotic group was associated with less blood loss and longer operative time. After the surgeon learning curves were overcome for each technique, the operative outcomes became similar between the two groups except longer operative time in the robotic group. After accumulating more cases of robotic gastrectomy, the operative time in the laparoscopic group decreased dramatically. Conclusions After overcoming the learning curves, the operative outcomes became similar between laparoscopic and robotic gastrectomy. The experience of robotic gastrectomy could affect the learning process of laparoscopic gastrectomy. PMID:25360767

We performed this prospective randomized study to evaluate what is the best reconstruction method after distal gastrectomy for gastric cancer. One hundred fifty-nine patients who underwent laparoscopy-assisted or open gastrectomy for gastric cancer were analyzed from March 2006 to August 2007. Billroth I (B-I) anastomosis, Billroth II (B-II) with Braun anastomosis, and Roux-en-Y (R-Y) anastomosis were applied randomly. Additionally, the patients were divided into two groups based on treatment type: laparoscopic and open operation. Endoscopy and hepatobiliary scans were performed to investigate gastric stasis and enterogastric reflux. The Gastrointestinal Quality of Life Index (GIQLI) was used to evaluate postoperative quality of life, and the hematologic test was used to assess nutritional aspect. Endoscopy revealed that reflux after the R-Y anastomosis procedure was significantly less frequent than after the other anastomosis types at 12 months. Comparison of the GIQLI and the nutritional parameters between the reconstruction types revealed that there were no differences, but a significantly higher GIQLI score was observed in the laparoscopic group immediately following the procedure (P = 0.042). R-Y anastomosis is superior to B-I and B-II with Braun anastomosis in terms of frequency of bile reflux, despite the fact that there is no difference in the postoperative quality-of-life index and nutritional status between reconstructive procedures. The laparoscopic approach is the better option than open surgery in terms of QOL in the immediate postoperative period.

Laparoscopic total gastrectomy is not widely performed because of the difficulty of esophagojejunal reconstruction. This study analyzed complication rates of two different methods for reconstruction by a circular stapler after totally laparoscopic total gastrectomy (TLTG). Between 2010 and 2014, clinical data of 19 patients who underwent TLTG for gastric adenocarcinoma were collected retrospectively. There were two methods to fix the anvil of a circular stapler into the distal esophagus: In the single-stapling technique (SST) group, Endo-PSI(II) was used for purse-suturing on the distal esophagus for reconstruction, and in the hemi-double-stapling technique (hemi-DST) group, the esophagus was cut by linear stapler with the entry hole of the anvil shaft opened after inserting the anvil tail. In both groups, surgical procedures were the same, except for the reconstruction. All TLTGs were performed securely without mortality. Intracorporeal laparoscopic esophagojejunal anastomosis was performed successfully for all the patients. In the hemi-DST group, four patients experienced anastomotic stenosis, three of whom required endoscopic balloon dilation. In contrast, no stenosis was seen in the SST group (p = 0.033). Anastomosis with SST is preferred to that with hemi-DST to minimize postoperative complications.

Laparoscopic distal gastrectomy has recently become accepted as a surgical option for early gastric cancer in the distal stomach, but laparoscopic total gastrectomy (LTG) has not become widespread because of technical difficulties of esophagojejunal anastomosis and splenic hilar lymphadenectomy. Splenic hilar lymphadenectomy should be employed in the treatment of advanced proximal gastric cancer to complete D2 dissection, but laparoscopically it is technically difficult even for skilled surgeons. Based on the evidence that prophylactic combined resection of spleen in total gastrectomy increased the risk of postoperative morbidity with no survival impact, surgeons have preferred laparoscopic spleen-preserving splenic hilar lymphadenectomy (LSPL) for advanced tumors without metastasis to splenic hilar nodes or invasion to the greater curvature of the stomach, and reports with LSPL have been increasing rather than LTG with splenectomy. In this paper, recent reports with laparoscopic splenic hilar lymphadenectomy were reviewed.

Leak following laparoscopic sleeve gastrectomy (LSG) is one of the most serious and devastating complications. Endoscopic stents can treat most early LSG leaks, but is not as effective for chronic LSG leaks/fistulae. The surgical options to treat a chronic leak/fistula after LSG are laparoscopic Roux en Y esophago-jejunostomy (LRYEJ) or laparoscopic Roux en Y fistulo-jejunostomy. We reviewed our prospective database for all patients with leak after LSG treated with LRYEJ. We have described our algorithm for managing LSG previously. We prefer to optimize the nutritional status of patients with enteral rather than parenteral nutrition and drain all collections prior to LRYEJ. We have treated four patients utilizing our technique of LRYEJ. Initial endoscopic stent placement was attempted in all four patients (two failed to resolve (50 %) and two had distal stenosis at the incisura not amenable to endoscopic stenting). We utilized enteral feeding through either naso-jejunal (NJ) or jejunostomy tube feeding in 3/4 (75 %) of patients, and in one patient with stenosis, we could not introduce a NJ tube endoscopically due to tight stricture. This patient was placed on total parenteral nutrition (TPN) and went on to develop pulmonary embolism. None of the patient developed leak after LRYEJ. The only patient with stenosis (25 %) had antecolic LRYEJ. In contrast, all patients who had retrocolic LRYGB laparoscopically did not develop stenosis. Laparoscopic Roux en Y esophago-jejunostomy for chronic leak/fistula after is safe and effective. Preoperative enteral nutrition is important.

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

A delta-shaped anastomosis in totally laparoscopic Billroth I gastrectomy could be performed easily and sufficiently using only laparoscopic linear staplers. However, the restricted maneuverability and severe blurring of these staplers along with their limited hemostability induced strain. In this study, we determined the feasibility and safety of performing delta-shaped anastomosis using the Endo GIA™ Reloads with Tri-Staple™ Technology combined with Endo GIA™ Ultra Universal stapler (Tri-Staple) with a particular focus on short-term surgical outcomes. We performed a single-institutional prospective interventional study (UMIN 000008014). The Tri-Staple was prospectively used on 23 consecutive patients who underwent a curative totally laparoscopic Billroth I gastrectomy with delta-shaped anastomosis. These patients were matched with the 19 patients previously treated using the ENDOPATH(®) ETS Articulating Linear Cutters (ETS) on clinical and demographic characteristics. There were no differences between the groups in anastomosis-related local complications, morbidity, non-anastomosis-related local complications, total systemic complications, and short-term outcomes with the exception of significantly reduced blood loss in the Tri-Staple group (ETS vs. Tri-Staple: 37 [10-306] vs. 15 [5-210] mL, p = 0.02). Intraoperative bleeding from the staple line was significantly reduced in the Tri-Staple group. The postoperative drain indwelling period (ETS vs. Tri-Staple, 6 [4-10] vs. 4 [2-43] days, p = 0.032), fasting period (5 [3-7] vs. 3 [3-24] days, p = 0.022), and hospital stay (14 [10-47] vs. 11 [6-58] days, p = 0.025) were significantly shorter in the Tri-Staple group. There was no mortality in this series. Acceleration assessed as indices of blurring of stapler tip might have a significant adverse influence on staple-line bleeding at stapling sites. Totally laparoscopic Billroth I distal gastrectomy using Tri-Staple was feasible and safe with favorable

This study aims to determine the incidence, etiology, and management options for symptomatic gastric obstruction caused by axially twisted sleeve gastrectomy. In this retrospective study, we reviewed medical charts of all morbidly obese patients who underwent laparoscopic sleeve gastrectomy. Patients who developed gastric obstruction symptoms and were diagnosed with twisted sleeve gastrectomy were identified and included in this study. From October 2005 to December 2015, there are 3634 morbidly obese patients who underwent laparoscopic sleeve gastrectomy (LSG). Eighty-six (2.3%) patients developed symptoms of gastric obstruction. Forty-five (1.23%) patients were included in this study. The mean time of presentation was 59.8 days after surgery. Upper GI contrast study was done routinely, and it was positive for axial twist in 37 (82%) patients. Abdominal CT with oral and IV contrast was done in eight (18%) when swallow study was equivocal. Endoscopic treatment was successful in 43 patients (95.5%). Sixteen patients were successfully managed by endoscopic stenting, and 29 patients had balloon dilation. The average numbers of dilation sessions were 1.7. Out of these 29 patients, 18 responded well to a single session of dilatation and did not require any further dilatation sessions. Two patients who failed to respond to three subsequent sessions of balloon dilation underwent laparoscopic adhesiolysis and gastropexy. Endoscopic stenting is an effective tool in management of axial rotation of sleeved stomach. Balloon dilation can also be effective in selected cases. Few cases might require laparoscopic adhesiolysis and gastropexy.

The aim of this study is to present our preliminary experience with indocyanine green fluorescence (IGF) imaging in laparoscopic sleeve gastrectomy. After dissection of the greater curve sleeve, gastrectomy is performed using a linear articulated stapler. Once the stomach is resected, an indocyanine green solution is prepared and injected in a periferic vein. A laparoscopic system with a high-definition camera system connected to a laparoscope equipped with a specific filter for optimal detection of the near-infrared fluorescence was used at all times as previously reported in a paper of Boni et al. A methylene blue test is routinely performed after near-infrared fluorescence, and a routine gastrografin upper gastrointestinal study is performed on postoperative day 2. We retrospectively identified 15 patients undergoing laparoscopic sleeve gastrectomy between April and October 2014. IGF imaging was used for all patients. A regular and homogeneous perfusion was observed along the entire gastric sleeve including the esophago-gastric junction. On the contrary, the excised specimen appeared devascularized at IGF imaging as expected. Intraoperative methylene blue test was negative in all cases. The contrast swallow did not document any leak. Neither clinical leak nor other complications occurred postoperatively (minimum follow-up of 2 months). IGF is a recent development in minimally invasive surgery. In this preliminary experience, IGF results resemble to intraoperative methylene blue test and postoperative contrast swallow ones. IGF allows a real-time assessment and gives a direct image of tissue perfusion and vascularization. Moreover, IGF may be helpful to explain the exact pathogenesis of gastric leak.

An experience with laparoscopic sleeve gastrectomy using the natural orifice specimen extraction (NOSE) technique. Bariatric surgery is nowadays the only long term effective obesity treatment method. Twenty one consecutive patients underwent laparoscopic sleeve gastrectomy with the use of natural orifice specimen extraction (NOSE) in the Surgical Clinic of Faculty Hospital Ostrava between May 2012 and August 2012. Inclusion criteria were the body mass index (BMI) higher than 35 kg/m2 or higher than 32 kg/m2 accompanied with relevant comorbidities. Among 21 patients in this series, there were three men (14.3%) and 18 women (85.7%). Their mean age was 40.9±10.2 years. Their mean preoperative BMI was 40.4±4.6 kg/m2. No patient had previous bariatric surgery, one patient had laparoscopic fundoplication. All operations were completed laparoscopically with no conversions to an open procedure. In two cases, laparoscopic cholecystectomy was performed and the gallbladder was extracted along with the gastric specimen by transgastric approach. Laparoscopic sleeve gastrectomy is a safe and effective bariatric procedure with low morbidity and mortality. Based on our initial experiences it could be an indication for NOSE with transgastric approach. Obese patients would benefit from this approach due to the elimination of wound complications (Tab. 2, Fig. 3, Ref. 22).

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

Patients were followed-up for a period of 12 months, evaluating the development of complications, reduction of gastric volume, and the weight loss associated with the surgery, as well as their impact on the improvement of comorbidities present at beginning of the study. There was a statistically a significantly reduction between the preoperative body mass index (BMI) and the BMI at 12 months after laparoscopic sleeve gastrectomy (p < 0.001), despite there being an increase in the gastric volume during follow-up, measured at one month and 12 months after surgery (p < 0.001). Five patients (6.85%) had complications, with none of them serious and with no deaths in the whole series. Laparoscopic sleeve gastrectomy is a safe and effective technique for the treatment of morbid obesity. Its use is associated with a significant reduction in the presence of comorbidities associated with obesity. Multicentre studies with a longer period of monitoring are required to confirm the efficacy and safety of this surgical technique. Copyright © 2015 Academia Mexicana de Cirugía A.C.

Gastric cancer in remnant stomach is a rare tumor but with poor prognosis. Compared with conventional open surgery, laparoscopic gastrectomy has potential benefits for these patients due to advantages resulting from its minimally invasive approach. Herein, we report on three patients with gastric cancer in remnant stomach who underwent laparoscopic total gastrectomy with intracorporeal esophagojejunostomy successfully. The operative time was 280, 250 and 225 minutes, the estimated blood loss was 100, 80 and 50 ml and the length of postoperative hospital stay was seven, eight and nine days respectively. Our experience has suggested that laparoscopic total gastrectomy with intracorporeal esophagojejunostomy can be a safe, feasible and promising option for patients with gastric cancer in remnant stomach.

The objective of this study was to evaluate patients who underwent laparoscopic Roux-en-Y gastric bypass and laparoscopic sleeve gastrectomy in terms of weight loss, metabolic parameters, and postoperative complications. Data on patients who underwent laparoscopic Roux-en-Y gastric bypass and laparoscopic sleeve gastrectomy with a diagnosis of morbid obesity between January 2012 and June 2014 were retrospectively evaluated. Patients were compared in terms of age, sex, body mass index, duration of operation, American Society of Anesthesiologists score, perioperative complications, length of hospital stay, and long term follow-up results. During the study period, 91 patients (45 laparoscopic Roux-en-Y gastric bypass and 46 laparoscopic sleeve gastrectomy) underwent bariatric surgery. There was no difference between the two groups in terms of preoperative patient characteristics. Both groups showed statistically significant weight loss and improvement in co-morbidities when compared with the preoperative period. Weight loss and improvement in metabolic parameters were similar in both groups. The duration of operation and hospital stay was longer in the laparoscopic Roux-en-Y gastric bypass group. Furthermore, the rate of total complications was significantly lower in the laparoscopic sleeve gastrectomy group. Laparoscopic sleeve gastrectomy is a safe and effective method with a significantly lower complication rate and length of hospital stay than laparoscopic Roux-en-Y gastric bypass, with similar improvement rates in metabolic syndrome.

Old age is regarded as the risk factor of major abdominal surgery due to the lack of functional reserve and the increased presence of comorbidities. This study aimed to evaluate the impact of old age on the surgical outcomes of totally laparoscopic gastrectomy for gastric cancer. This study enrolled 389 gastric cancer patients who underwent totally laparoscopic gastrectomy at Hanyang University Guri Hospital and ASAN Medical Center. The patients were classified into two groups according to age as those older than 70 years and those younger than 70 years. Early surgical outcomes such as operation time, postoperative complications, time to first flatus, days until soft diet began, and hospital stay were evaluated. No patient was converted to open surgery. The two groups differed significantly in terms of overall postoperative complication rate, time to first flatus, days until soft diet began, and hospital stay. The patients who underwent Roux-en-Y gastrojejunostomy differed in incidence of postoperative ileus but not in severe postoperative complication rate. The results of this study demonstrated that old age can have an effect on the surgical outcomes of totally laparoscopic gastrectomy. This study especially showed that elderly patients are affected by the return of bowel movement after totally laparoscopic gastrectomy. On the other hand, however, it is presumed that old age has not had a serious impact on surgical outcomes in totally laparoscopic gastrectomy because no difference in the severe postoperative complication rate was observed.

Bariatric surgery has shown to produce the most predictable and tangible results for weight loss, with laparoscopic sleeve gastrectomy's being the most popular one of them. However, the occurrence of previously undiagnosed diseases can be encountered during bariatric operations. The work has been reported in line with the SCARE criteria. This is the case of a 54year old morbidly obese female, presenting to our hospital for a laparoscopic sleeve gastrectomy. During her procedure, it was discovered that she has an accessory spleen on the fundus of her stomach. The decision was made to resect it with the specimen of the stomach for histopathalogical examination. Incidental findings during routine bariatric surgery are a common occurance, and therefore prompt and effective intra-op management is key to the prognosis of the patient. Accessory spleens, although uncommon, tend to be asymptomatic. However, if undiagnosed, could present with dangerous consequences. Copyright © 2017. Published by Elsevier Ltd.

The reduction in the preferences for sweet and fat containing tastes in obese patients who underwent bariatric surgery was relatively well shown; however, there are only limited data on the changes in the sensitivity of other tastes like sour, salty, and bitter. We investigated the changes in gustatory sensitivity of 52 morbidly obese patients (M/F, 22/30; age range, 19-60 years; BMI range, 32.5-63.0 kg/m(2)) after laparoscopic sleeve gastrectomy. The surgery was performed by the same surgeon using 5 ports technique. Gustatory sensitivity was tested preoperatively and 1 and 3 months after the surgery using standardized Taste Strips test. There was a statistically significant improvement in the taste acuity to sweet, sour, salty, and bitter tastants in morbidly obese patients after the laparoscopic sleeve gastrectomy during the follow-up period of 3 months. Median whole test scores of the patients were increased from 11.5 preoperatively to 14 in the first and third months. In this study, we were able to show the significant improvement in gustatory sensitivity of morbidly obese patients after laparoscopic sleeve gastrectomy for the first time in literature. © The Author(s) 2016.

In Japan, distal gastrectomy is the most common operation performed to treat gastric cancer. However, this procedure often leads to postoperative problems such as weight loss. We assessed the changes of nutritional status early after operation and the associations of the postoperative body weight (as a percentage of the preoperative weight) and background factors in patients who underwent distal gastrectomy. We measured the changes of nutritional indices (mean body weight, TSF, AMC and Alb) and nutrition intake on the day before operation (before operation), before postoperative resumption of oral intake (before oral intake), and on the fifth day of a soft rice porridge diet (after soft rice). Background factors included gender, age, preoperative BMI and preoperative exercise. Mean body weight, TSF, and AMC significantly decreased from before operation, to the day before oral intake and to the day after soft rice. The postoperative body weight was not associated with the gender, age, or preoperative BMI. The frequency of regular preoperative exercise was associated with the postoperative body weight. The total daily calorie intake was 1,664 kcal (before operation), 398 kcal (before oral intake), and 949 kcal (after soft rice). To conclude, nutritional status changes significantly after distal gastrectomy. Early nutrition intervention may be needed in patients who undergo distal gastrectomy for gastric cancer.

Laparoscopy-assisted pylorus-preserving gastrectomy has been increasingly reported as a treatment for early gastric cancer located in the middle third of the stomach because of its low invasiveness and preservation of pyloric function. Advantages of a totally laparoscopic approach to distal gastrectomy, including small wound size, minimal invasiveness, and safe anastomosis, have been recently reported. Here, we introduce a new procedure for intracorporeal gastro-gastrostomy combined with totally laparoscopic pylorus-preserving gastrectomy (TLPPG). The stomach is transected after sufficient lymphadenectomy with preservation of infrapyloric vessels and vagal nerves. The proximal stomach is first transected near the Demel line, and the distal side is transected 4 to 5 cm from the pyloric ring. To create end-to-end gastro-gastrostomy, the posterior wall of the anastomosis is stapled with a linear stapler and the anterior wall is made by manual suturing intracorporeally. We retrospectively assessed the postoperative surgical outcomes via medical records. The primary endpoint in the present study is safety. Sixteen patients underwent TLPPG with intracorporeal reconstruction. All procedures were successfully performed without any intraoperative complications. The mean operative time was 275 min, with mean blood loss of 21 g. With the exception of one patient who had gastric stasis, 15 patients were discharged uneventfully between postoperative days 8 and 11. Our novel hybrid technique for totally intracorporeal end-to-end anastomosis was performed safely without mini-laparotomy. This technique requires prospective validation.

The indications for sleeve gastrectomy as a primary procedure for the surgical treatment of morbid obesity have increased worldwide. Pain is the most common complaint for patients on the first day after laparoscopic sleeve gastrectomy. There are various methods for decreasing pain after laparoscopic sleeve gastrectomy such as the use of intraperitoneal bupivacaine hydrochloride. This clinical trial was an attempt to discover the effects of intraperitoneal bupivacaine hydrochloride on alleviating postoperative pain after laparoscopic sleeve gastrectomy. In general, 120 patients meeting the inclusion criteria were enrolled. Patients were randomly allocated into two interventions and control groups using a balanced block randomization technique. One group received intraperitoneal bupivacaine hydrochloride (30 cm 3 ), and the other group served as the control one and did not receive bupivacaine hydrochloride. Diclofenac suppository and paracetamol injection were administered to both groups for postoperative pain management. The mean subjective postoperative pain score was significantly decreased in patients who received intraperitoneal bupivacaine hydrochloride within the first 24 h after the surgery; thus, the instillation of bupivacaine hydrochloride was beneficial in managing postoperative pain. The intraoperative peritoneal irrigation of bupivacaine hydrochloride (30 cm 3 , 0.25%) in sleeve gastrectomy patients was safe and effective in reducing postoperative pain, nausea, and vomiting (IRCT2016120329181N4).

[Laparoscopic Proximal Gastrectomy as a Surgical Treatment for Upper Third Early Gastric Cancer].

Recently, the incidence of upper third gastric cancer has increased, and with it the number of endoscopic submucosal dissection (ESD) procedures performed has been increasing. However, if ESD is not indicated or non-curable, surgical treatment may be necessary. In the case of lower third gastric cancer, it is possible to preserve the upper part of the stomach; however, in the case of upper third gastric cancer, total gastrectomy is still the standard treatment option, regardless of the stage. This is due to the complications associated with upper third gastric cancer, such as gastroesophageal reflux after proximal gastrectomy rather than oncologic problems. Recently, the introduction of the double tract reconstruction method after proximal gastrectomy has become one of the surgical treatment methods for upper third early gastric cancer. However, since there has not been a prospective comparative study evaluating its efficacy, the ongoing multicenter prospective randomized controlled trial (KLASS-05) comparing laparoscopic proximal gastrectomy with double tract reconstruction and laparoscopic total gastrectomy is expected to be important for determining the future of treatment of upper third early gastric cancer.

Olfactory abilities of the patients are known to be altered by eating and metabolic disorders, including obesity. There are only a number of studies investigating the effect of obesity on olfaction, and there is limited data on the changes in olfactory abilities of morbidly obese patients after surgical treatment. Here we investigated the changes in olfactory abilities of 54 morbidly obese patients (M/F, 22/32; age range 19-57 years; body mass index (BMI) range 30.5-63.0 kg/m(2)) after laparoscopic sleeve gastrectomy. A laparoscopic sleeve gastrectomy was performed by the same surgeon using five-port technique. Olfactory abilities were tested preoperatively and 1, 3, and 6 months after the surgery using a standardized Sniffin' Sticks Extended Test kit. Analyses of variance indicated statistically significant improvement in T, D, and I scores of morbidly obese patients within time factors (preoperative vs. 1, 3, and 6 months; 1 vs. 3 and 6 months; and 3 vs. 6 months; p < 0.001 for all). There was a statistically significant improvement in overall TDI scores with an increase from 25 to 41 during the 6 months follow-up period (p < 0.001 for all). Here, for the first time in literature, we were able to show the significant improvement in olfactory abilities of morbidly obese patients after laparoscopic sleeve gastrectomy.

Laparoscopic total gastrectomy (LTG) has been widely performed for gastric cancer in China, Korea, and Japan. The current status of this surgical approach needs to be investigated. During the 11th China-Korea-Japan Laparoscopic Gastrectomy Joint Seminar in Shanghai, China, on 5 March 2016, a questionnaire was completed by 65 experts in LTG. The survey included questions on surgical indication, operation team, laparoscopic instruments, and operative procedures. Of the 65 respondents, 35 (53.8%) were from China, 18 (27.7%) were from Korea, and 12 (18.5%) were from Japan. Surgeons have various indications for LTG. Among respondents, stage II gastric cancer (42.9%) was the most acceptable indication, but Japanese surgeons were more cautious on this issue (P = 0.005). Using a flexible scope was more popular with Japanese surgeons than with others (P = 0.003). A goose-neck curved grasper was used more often in China and Korea than in Japan (P = 0.006). Chinese surgeons preferred vertical subxiphoid mini-laparotomy rather than vertical transumbilical laparotomy. Intracorporeal reconstruction (73.0%) was most frequently adopted for LTG. Linear staplers (53.8%) and circular staplers (42.1%) were both popular for esophagojejunostomy. However, jejunojejunostomy was more often conducted extracorporeally (67.7%), in which case a linear stapler (86.4%) was usually selected. Significant differences were observed between the three countries with regard to reinforcement of the duodenal stump (P = 0.018) and closure of Peterson's space (P < 0.001). This survey on LTG involving surgeons from China, Korea, and Japan clearly informed the current practice of this surgical approach and will likely aid future research studies as well as clinical treatment for gastric cancer. © 2017 Japan Society for Endoscopic Surgery, Asia Endosurgery Task Force and John Wiley & Sons Australia, Ltd.

The volume-outcome relationship in laparoscopic surgery is controversial. This study was designed to identify differences in laparoscopic gastrectomy outcomes between a low-volume hospital and a high-volume center and to provide guidelines for overcoming the problems associated with a low-volume hospital. From April 2009 to November 2012, one surgeon performed 134 totally laparoscopic distal gastrectomies (TLDGs) at a high-volume center (HVC; ASAN Medical Center) and at a low-volume hospital (LVH; Hanyang University Guri Hospital). All laparoscopically assisted gastrectomies were excluded from this study. During the early period of laparoscopic gastrectomy at the low-volume hospital, TLDG with Roux-en-Y gastrojejunostomy (RYGJ) was performed according to the surgeon's choice. The reconstruction method was classified as gastroduodenostomy (GD) or RYGJ. Early surgical outcomes achieved at the LVH were investigated and compared with those obtained at the HVC. The early surgical outcomes differed significantly between the two hospitals. In particular, the postoperative complication rate for the patients who underwent TLDG RYGJ at the LVH was higher than at the HVC (LVH 15.4 % vs. HVC 0 %; p = 0.037). Furthermore, significant differences were observed in the mean operation time (TLDG GD: LVH 141.0 min vs. HVC 117.4 min, p = 0.001; TLDG RYGJ: LVH 186.3 min vs. HVC 134.6 min, p = 0.009) and length of hospital stay (TLDG GD: LVH 8.1 days vs. HVC 7.2 days, p = 0.044; TLDG RYGJ: LVH 11.5 day vs. HVC 6.8 day, p = 0.009). Although all the operations were performed by one experienced surgeon, the early surgical outcomes differed significantly between the low- and high-volume hospitals. Low-volume hospitals often lack well-trained surgical professionals such as first assistants and scrub nurses. Therefore, the authors recommend that a surgeon who works at an LVH should assess potential personnel shortages and find a solution before operating.

Laparoscopic sleeve gastrectomy (LSG) has gained significant popularity in the USA, and consequently resulted in patients experiencing new-onset gastroesophageal reflux disease (GERD) following this bariatric procedure. Patients with GERD refractory to medical therapy present a more challenging situation limiting the surgical options to further treat the de novo GERD symptoms since the gastric fundus to perform a fundoplication is no longer an option. The aim of this study is to determine if the LINX® magnetic sphincter augmentation system is a safe and effective option for patients with new gastroesophageal reflux disease following laparoscopic sleeve gastrectomy. This study was conducted at the University Medical Center. This is a retrospective review of seven consecutive patients who had a laparoscopic LINX® magnetic sphincter device placement for patients with refractory gastroesophageal reflux disease after laparoscopic sleeve gastrectomy between July 2014 and April 2015. All patients were noted to have self-reported greatly improved gastroesophageal reflux symptoms 2-4 weeks after their procedure. They were all noted to have statistically significant improved severity and frequency of their reflux, regurgitation, epigastric pain, sensation of fullness, dysphagia, and cough symptoms in their postoperative GERD symptoms compared with their preoperative evaluation. This is the first reported pilot case series, illustrating that the LINX® device is a safe and effective option in patients with de novo refractory gastroesophageal reflux disease after a laparoscopic sleeve gastrectomy despite appropriate weight loss.

The purpose of this prospective study was to investigate changes in lipid indices associated with whole body composition during 1 year of follow-up after laparoscopic gastrectomy. Thirty-seven patients with benign and malignant gastric neoplasm who underwent laparoscopic gastrectomy were prospectively enrolled. None of the patients were treated with adjuvant chemotherapy. Lipid indices and body composition were measured preoperatively and at six and 12 months after laparoscopic gastrectomy. Lipid indices included total cholesterol (TC), triglyceride (TG), low-density lipoprotein cholesterol (LDL-C) and high-density lipoprotein cholesterol (HDL-C). Body weight, fat and lean body mass (LBM) were measured by dual-energy X-ray absorptiometry and the change in fat and LBM in the trunk, arms and legs was compared. Body weight significantly decreased from 63.0 ± 11.1 kg preoperatively to 56.8 ± 10.6 kg 12 months after laparoscopic gastrectomy, with a mean of 7.1% (4.6 kg) weight loss. Fat and LBM loss contributed 68.4% (3.1 kg) and 30.1% (1.4 kg) of the total weight loss, respectively. In both the non-obese and obese groups, body weight, fat and LBM did not change significantly between 6 months and 12 months after gastrectomy. TC and LDL-C levels significantly decreased during the first six-month period and HDL-C significantly increased until 12 months after gastrectomy in the non-obese group. In the obese group, the degree of reduction in fat mass was significantly higher and the LBM/weight ratio significantly increased compared with the non-obese group. However, there was no significant change in lipid indices in the obese group. The TG level was significantly correlated with fat, especially with trunk fat. Gastrectomy resulted in improved lipid indices and a reduction in body weight, fat and LBM. The HDL-C significantly increased in the non-obese group for 1 year after gastrectomy and the reduction of TG level was positively correlated with fat

Bariatric surgery improves metabolic diseases and alters the intestinal microbiota in animals and humans, but different procedures reportedly have different impacts on the intestinal microbiota. We developed laparoscopic sleeve gastrectomy with duodenojejunal bypass (LSG-DJB) as an alternative to laparoscopic Roux-en-Y gastric bypass (LRYGB) in addition to laparoscopic sleeve gastrectomy (LSG) for Japanese patients with obesity. We investigated the precise change in the intestinal microbiota induced by these procedures in the present study. A prospective observational study of 44 Japanese patients with obesity was conducted [22 patients underwent LSG, 18 underwent LSG-DJB, and 4 underwent laparoscopic adjustable gastric banding (LAGB)]. The patients' clinical parameters and intestinal microbiota were investigated before and for 6 months after surgery. The microbiota was analyzed by a 16S rDNA method. LSG and LSG-DJB significantly improved the metabolic disorders in the patients with obesity. The proportion of the phylum Bacteroidetes and order Lactobacillales increased significantly in the LSG group, and that of the order Enterobacteriales increased significantly in the LSG-DJB group. LSG and LSG-DJB improved obesity and type 2 diabetes in Japanese patients with obesity, but the impact of LSG-DJB on the intestinal microbiota differed from that of LSG. This difference in the impact on the intestinal environment could explain the different efficacies of LSG and LSG-DJB in terms of their ability to resolve metabolic disorders in the clinical setting.

Laparoscopic sleeve gastrectomy for treatment of morbid obesity has increased substantially despite the lack of long-term results compared with laparoscopic Roux-en-Y gastric bypass. To determine whether laparoscopic sleeve gastrectomy and laparoscopic Roux-en-Y gastric bypass are equivalent for weight loss at 5 years in patients with morbid obesity. The Sleeve vs Bypass (SLEEVEPASS) multicenter, multisurgeon, open-label, randomized clinical equivalence trial was conducted from March 2008 until June 2010 in Finland. The trial enrolled 240 morbidly obese patients aged 18 to 60 years, who were randomly assigned to sleeve gastrectomy or gastric bypass with a 5-year follow-up period (last follow-up, October 14, 2015). Laparoscopic sleeve gastrectomy (n = 121) or laparoscopic Roux-en-Y gastric bypass (n = 119). The primary end point was weight loss evaluated by percentage excess weight loss. Prespecified equivalence margins for the clinical significance of weight loss differences between gastric bypass and sleeve gastrectomy were -9% to +9% excess weight loss. Secondary end points included resolution of comorbidities, improvement of quality of life (QOL), all adverse events (overall morbidity), and mortality. Among 240 patients randomized (mean age, 48 [SD, 9] years; mean baseline body mass index, 45.9, [SD, 6.0]; 69.6% women), 80.4% completed the 5-year follow-up. At baseline, 42.1% had type 2 diabetes, 34.6% dyslipidemia, and 70.8% hypertension. The estimated mean percentage excess weight loss at 5 years was 49% (95% CI, 45%-52%) after sleeve gastrectomy and 57% (95% CI, 53%-61%) after gastric bypass (difference, 8.2 percentage units [95% CI, 3.2%-13.2%], higher in the gastric bypass group) and did not meet criteria for equivalence. Complete or partial remission of type 2 diabetes was seen in 37% (n = 15/41) after sleeve gastrectomy and in 45% (n = 18/40) after gastric bypass (P > .99). Medication for dyslipidemia was discontinued in 47% (n�

Sleeve gastrectomy is increasingly used in the treatment of morbid obesity, but its long-term outcome vs the standard Roux-en-Y gastric bypass procedure is unknown. To determine whether there are differences between sleeve gastrectomy and Roux-en-Y gastric bypass in terms of weight loss, changes in comorbidities, increase in quality of life, and adverse events. The Swiss Multicenter Bypass or Sleeve Study (SM-BOSS), a 2-group randomized trial, was conducted from January 2007 until November 2011 (last follow-up in March 2017). Of 3971 morbidly obese patients evaluated for bariatric surgery at 4 Swiss bariatric centers, 217 patients were enrolled and randomly assigned to sleeve gastrectomy or Roux-en-Y gastric bypass with a 5-year follow-up period. Patients were randomly assigned to undergo laparoscopic sleeve gastrectomy (n = 107) or laparoscopic Roux-en-Y gastric bypass (n = 110). The primary end point was weight loss, expressed as percentage excess body mass index (BMI) loss. Exploratory end points were changes in comorbidities and adverse events. Among the 217 patients (mean age, 45.5 years; 72% women; mean BMI, 43.9) 205 (94.5%) completed the trial. Excess BMI loss was not significantly different at 5 years: for sleeve gastrectomy, 61.1%, vs Roux-en-Y gastric bypass, 68.3% (absolute difference, -7.18%; 95% CI, -14.30% to -0.06%; P = .22 after adjustment for multiple comparisons). Gastric reflux remission was observed more frequently after Roux-en-Y gastric bypass (60.4%) than after sleeve gastrectomy (25.0%). Gastric reflux worsened (more symptoms or increase in therapy) more often after sleeve gastrectomy (31.8%) than after Roux-en-Y gastric bypass (6.3%). The number of patients with reoperations or interventions was 16/101 (15.8%) after sleeve gastrectomy and 23/104 (22.1%) after Roux-en-Y gastric bypass. Among patients with morbid obesity, there was no significant difference in excess BMI loss between laparoscopic sleeve gastrectomy and laparoscopic Roux

Laparoscopic distal gastrectomy (LDG) with D1+ lymph node dissection (LND) for early gastric cancer has been widely accepted. However, LDG with D2 LND for advanced gastric cancer remains in limited use. The aim of this retrospective study was to clarify the safety of LDG with D2 LND for gastric cancer. From January 2010 to September 2014, 296 patients underwent LDG; those who received D1+ LND (n = 230) or D2 LND (n = 66) were included in this study. The clinicopathological characteristics and short-term outcomes of both groups were investigated and compared. There were no significant differences in the incidence of postoperative complications between the two groups. However, the frequency of infectious intra-abdominal complications was higher in the D2 LND group than in the D1+ LND group. Additionally, a lower risk of infectious intra-abdominal complications was seen with certified than with uncertified operators. The evaluation of short-term outcomes demonstrated that LDG with D2 LND is generally feasible. However, the risk of infectious intra-abdominal complications is higher with D2 LND than with D1+ LND. Also, D2 LND should be performed by trained operators. © 2016 Japan Society for Endoscopic Surgery, Asia Endosurgery Task Force and John Wiley & Sons Australia, Ltd.

Although laparoscopic total gastrectomy (LTG) is considered a technically demanding procedure with safety issues, it has been performed in several hospitals in Japan. Data from a nationwide web-based data entry system for surgical procedures (NCD) that started enrollment in 2011 are now available for analysis. A retrospective cohort study was conducted using data from 32,144 patients who underwent total gastrectomy and were registered in the NCD database between January 2012 and December 2013. Mortality and morbidities were compared between patients who received LTG and those who underwent open total gastrectomy (OTG) in the propensity score-matched Stage I cohort and Stage II-IV cohort. There was no significant difference in mortality rate between LTG and OTG in both cohorts. Operating time was significantly longer in LTG while the blood loss was smaller. In the Stage I cohort, LTG, performed in 33.6% of the patients, was associated with significantly shorter hospital stay but significantly higher incidence of readmission, reoperation, and anastomotic leakage (5.4% vs. 3.6%, p < 0.01). In the Stage II-IV cohort, LTG was performed in only 8.8% of the patients and was associated with significantly higher incidence of leakage (5.7% vs. 3.6%, p < 0.02) although the hospital stay was shorter (15 days vs. 17 days, p < 0.001). LTG was more discreetly introduced than distal gastrectomy, but remained a technically demanding procedure as of 2013. This procedure should be performed only among the well-trained and informed laparoscopic team.

Minimally invasive procedures for pancreatic pathologies are increasingly being used, including distal pancreatectomy. This study aimed to assess the indications for and outcomes of the da Vinci distal pancreatectomy procedure. We reviewed the medical records of patients who underwent pancreatic head resection from April 2009 to September 2013. Four patients (mean age, 52.7 years) underwent da Vinci distal pancreatectomy and 10 (mean age, 68.0 +/- 12.1 years) underwent laparoscopic distal pancreatectomy. The mean surgical duration was 292 +/- 153 min and 306 +/- 29 min, the mean blood loss was 153 +/- 71 mL and 61.7 +/- 72 mL, and the mean postoperative length of stay was 24 +/- 11 days and 14 +/- 3 days in the da Vinci distal pancreatectomy and laparoscopic distal pancreatectomy groups, respectively. One patient who underwent da Vinci distal pancreatectomy developed a pancreatic fistula, while 2 patients in the laparoscopic distal pancreatectomy group developed splenic ischemia and gastric torsion, respectively. Laparoscopic and robotic pancreatic resection were both safe and feasible in selected patients with distal pancreatic pathologies. Further studies are necessary to clarify the role of robotic surgery in the advanced laparoscopic era.

Billroth-I (BI) is a simple, physiological method of reconstruction following distal gastrectomy. In actuality, postoperative QOL is by no means favorable due to the high incidence of post-gastrectomy syndrome. The aim of this study is to assess the safety and efficacy of boomerang-shaped jejunal interposition (BJI) after distal gastrectomy. Sixty-six patients with early gastric cancer underwent the BI procedure (n = 33) or BJI (n = 33) after distal gastrectomy, following which they were compared for 5 years. Tumor characteristics, operative details, postoperative complications and complaints, number of meals, and body weight were analyzed. Patients were followed up by endoscopy every 12 months. There were no significant differences in the incidence of postoperative complications. The incidence of heartburn (30 vs. 0 %, P = 0.0009) and oral bitterness (33 vs. 6 %, P = 0.0112) were significantly lower in the BJI cases. Endoscopic findings revealed significantly lower incidences of reflux esophagitis (24 vs. 0 %, P = 0.0051) and remnant gastritis (70 vs. 3 %, P < 0.0001) in the BJI group. The incidence of food stasis was low in both groups (12 vs. 15 %). In the BJI group, 30 patients (90 %) were eating 3 meals/day within 12 months, whereas in the BI group, 16 patients (48 %) were still eating 5 meals/day at 12 months or later. BJI is as safe as BI, but is better in terms of improvement in bile reflux and food intake without stasis. This procedure, therefore, appears to be a useful method for reconstruction after distal gastrectomy.

The esophageal jejunum anastomosis of the digestive tract reconstruction techniques in laparoscopic total gastrectomy includes two categories: circular stapler anastomosis techniques and linear stapler anastomosis techniques. Circular stapler anastomosis techniques include manual anastomosis method, purse string instrument method, Hiki improved special anvil anastomosis technique, the transorally inserted anvil(OrVil(TM)) and reverse puncture device technique. Linear stapler anastomosis techniques include side to side anastomosis technique and Overlap side to side anastomosis technique. Esophageal jejunum anastomosis technique has a wide selection of different technologies with different strengths and the corresponding limitations. This article will introduce research progress of laparoscopic total gastrectomy esophagus jejunum anastomosis from both sides of the development of anastomosis technology and the selection of anastomosis technology.

Mechanical stapler is regarded as a good alternative to the hand sewing technique, when used in gastric reconstruction. The circular stapling method has been widely applied to gastrectomy (open orlaparoscopic), for gastric cancer. We illustrated and compared the hand-sutured method to the circular stapling method, for Billroth-II, in patients who underwent laparoscopy assisted distal gastrectomy for gastric cancer. Between April 2009 and May 2011, 60 patients who underwent laparoscopy assisted distal gastrectomy, with Billroth-II, were enrolled. Hand-sutured Billroth-II was performed in 40 patients (manual group) and circular stapler Billroth-II was performed in 20 patients (stapler group). Clinicopathological features and post-operative outcomes were evaluated and compared between the two groups. Nosignificant differences were observed in clinicopathologic parameters and post-operative outcomes, except in the operation times. Operation times and anastomosis times were significantly shorter in the stapler group (P=0.004 and P<0.001). Compared to the hand-sutured method, the circular stapling method can be applied safely and more efficiently, when performing Billroth-II anastomosis, after laparoscopy assisted distal gastrectomy in patients with gastric cancer.

Gastro-oesophageal reflux disease (GORD) is a common obesity-related co-morbidity that is assessed objectively by 24-h pH monitoring. Some concerns have been raised regarding the risk of de novo GORD or exacerbation of pre-existing GORD after laparoscopic sleeve gastrectomy. Here, 24-h pH monitoring was used to assess the influence of laparoscopic sleeve gastrectomy on postoperative GORD in obese patients with or without preoperative GORD. From July 2012 to September 2014, all patients scheduled for laparoscopic sleeve gastrectomy were invited to participate in a prospective follow-up. Patients who underwent preoperative 24-h pH monitoring were asked to repeat the examination 6 months after operation. GORD was defined as an oesophageal pH < 4 for at least 4·2 per cent of the total time recorded. Of 89 patients, 76 had preoperative pH monitoring for GORD evaluation and 50 had postoperative reassessment. Patients without (group 1, 29 patients) or with (group 2, 21 patients) preoperative GORD were similar regarding age, sex ratio and body mass index. In group 1, the median (i.q.r.) total time at pH < 4 was significantly higher after surgery than before: 5·6 (2·5-9·5) versus 1·6 (0·7-2·9) per cent (P < 0·001). Twenty of the 29 patients experienced de novo GORD as determined by 24-h pH monitoring (P < 0·001). In group 2, total time at pH < 4 after surgery was no different from the preoperative value: 5·9 (3·9-10·7) versus 7·7 (5·2-10·3) per cent (P = 0·296). Laparoscopic sleeve gastrectomy was associated with de novo GORD in over two-thirds of patients, but did not seem to exacerbate existing GORD. © 2016 BJS Society Ltd Published by John Wiley & Sons Ltd.

Laparoscopic Roux-en-Y gastric bypass (RYGBP) is a common procedure for morbid obesity. After RYGBP, the bypassed stomach is unavailable for follow-up. Biermer anemia is an autoimmune atrophic gastritis inducing vitamin B12 deficiency and it is a risk factor for gastric carcinoma. A 41-year-old woman with a long history of morbid obesity presented with a BMI of 56 kg/m2. She had anemia (Hb 9.9 g/dL), and atrophic gastritis was found endoscopically. We performed a laparoscopic RYGBP with subtotal gastrectomy, to avoid the risk of gastric carcinoma in the bypassed stomach. The patient was discharged 9 days after the operation without complication. At 18 months follow-up, her BMI was 39 kg/m2 (50% excess weight loss). Laparoscopic RYGBP with subtotal gastrectomy is a safe treatment for morbid obesity, which should be considered for patients with a risk factor for gastric carcinoma.

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

AIM To investigate the detrimental impact of loss of reservoir capacity by comparing total gastrectomy (TGRY) and distal gastrectomy with the same Roux-en-Y (DGRY) reconstruction. The study was conducted using an integrated questionnaire, the Postgastrectomy Syndrome Assessment Scale (PGSAS)-45, recently developed by the Japan Postgastrectomy Syndrome Working Party. METHODS The PGSAS-45 comprises 8 items from the Short Form-8, 15 from the Gastrointestinal Symptom Rating Scale, and 22 newly selected items. Uni- and multivariate analysis was performed on 868 questionnaires completed by patients who underwent either TGRY (n = 393) or DGRY (n = 475) for stage I gastric cancer (52 institutions). Multivariate analysis weighed of six explanatory variables, including the type of gastrectomy (TGRY/DGRY), interval after surgery, age, gender, surgical approach (laparoscopic/open), and whether the celiac branch of the vagus nerve was preserved/divided on the quality of life (QOL). RESULTS The patients who underwent TGRY experienced the poorer QOL compared to DGRY in the 15 of 19 main outcome measures of PGSAS-45. Moreover, multiple regression analysis indicated that the type of gastrectomy, TGRY, most strongly and broadly impaired the postoperative QOL among six explanatory variables. CONCLUSION The results of the present study suggested that TGRY had a certain detrimental impact on the postoperative QOL, and the loss of reservoir capacity could be a major cause. PMID:28373774

Staple line leak is a serious complication of sleeve gastrectomy. Intraoperative methylene blue and air leak tests are routinely used to evaluate for leak; however, the utility of these tests is controversial. We hypothesize that the practice of routine intraoperative leak testing is unnecessary during sleeve gastrectomy. A retrospective cohort study was designed using a prospectively collected database of seven bariatric surgeons from two institutions. All patients who underwent sleeve gastrectomy from March 2012 to November 2014 were included. The performance of intraoperative leak testing and the type of test (air or methylene blue) were based on surgeon preference. Data obtained included BMI, demographics, comorbidity, presence of intraoperative leak test, result of test, and type of test. The primary outcome was leak rate between the leak test (LT) and no leak test (NLT) groups. SAS version 9.4 was used for univariate and multivariate analyses. A total of 1550 sleeve gastrectomies were included; most were laparoscopic (99.8%), except for one converted and two open cases. Routine intraoperative leak tests were performed in 1329 (85.7%) cases, while 221 (14.3%) did not have LTs. Of the 1329 cases with LTs, there were no positive intraoperative results. Fifteen (1%) patients developed leaks, with no difference in leak rate between the LT and NLT groups (1 vs. 1%, p = 0.999). After adjusting for baseline differences between the groups with a propensity analysis, the observed lack of association between leak and intraoperative leak test remained. In this cohort, leaks presented at a mean of 17.3 days postoperatively (range 1-67 days). Two patients with staple line leaks underwent repeat intraoperative leak testing at leak presentation, and the tests remained negative. Intraoperative leak testing has no correlation with leak due to laparoscopic sleeve gastrectomy and is not predictive of the later development of staple line leak.

Remnant gastric cancer (RGC) and gastric stump cancer after distal gastrectomy (DG) are recognized as the same clinical entity. In this review, the current knowledges as well as the non-settled issues of RGC are presented. Duodenogastric reflux and denervation of the gastric mucosa are considered as the two main factors responsible for the development of RGC after benign disease. On the other hand, some precancerous circumstances which already have existed at the time of initial surgery, such as atrophic gastritis and intestinal metaplasia, are the main factors associated with RGC after gastric cancer. Although eradication of Helicobacter pylori (H. pylori) in remnant stomach is promising, it is still uncertain whether it can reduce the risk of carcinogenesis. Periodic endoscopic surveillance after DG was reported useful in detecting RGC at an early stage, which offers a chance to undergo minimally invasive endoscopic treatment or laparoscopic surgery and leads to an improved prognosis in RGC patients. Future challenges may be expected to elucidate the benefit of eradication of H. pylori in the remnant stomach if it could reduce the risk for RGC, to build an optimal endoscopic surveillance strategy after DG by stratifying the risk for development of RGC, and to develop a specific staging system for RGC for the standardization of the treatment by prospecting the prognosis.

Staple-line bleeding and leakage are the most common serious complications of laparoscopic sleeve gastrectomy. The relationship between multiple stapler firings and higher risk of postoperative complications is well defined in colorectal surgery but has not been addressed in bariatric procedures so far. Identification of new factors such as "the numbers of stapler firings used during laparoscopic sleeve gastrectomy (LSG)" as a predictor for complications can lead to optimization of the patient care at bariatric centers. To determine the association between perioperative morbidity and the number of stapler firings during laparoscopic sleeve gastrectomy. This observational study was based on retrospective analysis of prospectively collected data in patients operated on for morbid obesity in a teaching hospital/tertiary referral center for general surgery. The patients who underwent LSG were analyzed in terms of the number of stapler firings used as a new potential risk predictor for postoperative complications after surgery, adjusting for other patient- and treatment-related factors. The study included 333 patients (209 women, 124 men, mean age: 40 ±11). During the first 30 days after surgery, complications were observed in 18 (5.41%) patients. Multivariate analysis showed that prolonging operative time increased morbidity (every minute, OR = 1.01; 95% CI: 1.00-1.02) and the complication rate increased with the number of stapler firings (every firing, OR = 1.91; 95% CI: 1.09-3.33; p = 0.023). Additional stapler firings above the usual number and a prolonged operation should alert a surgeon and the whole team about increased risk of postoperative complications.

The incidence of incidental pathology found during laparoscopic bariatric surgery has been estimated to be around 2%, and gastric gastrointestinal stromal tumors (GISTs) have been found in 0.8% of patients, constituting a rather uncommon finding. Safe laparoscopic resection of gastric GISTs is an established procedure and has been described associated to gastric Roux-en-Y bypass for morbid obesity. We discuss one case of a gastric GIST incidentally discovered during laparoscopic sleeve gastrectomy for morbid obesity. The procedure was performed via laparoscopy, and the patient recovered without any complication. Currently, the patient has lost weight according to what was expected, is asymptomatic, and free of disease.

To summarize the surgical technique and perioperative management of laparoscopic sleeve gastrectomy (LSG). A total of 57 morbid obesity patients undergoing LSG surgery from May 2010 to December 2012 were enrolled in the study, whose clinical data in perioperative period were analyzed retrospectively. These patients had more than 1 year of follow-up. All the patients received preoperative preparation and postoperative management, and postoperative excess weight loss(EWL%) and improvement of preoperative complications was evaluated. All the cases completed the operation under laparoscopy, except 1 case because of the abdominal extensive adhesion. The average operation time was(102.0±15.2) min and the mean intraoperative blood loss (132.3±45.6) ml. Of 2 postoperative hemorrhage patients, 1 case received conservative treatment, and another one underwent laparoscopic exploration. The EWL% at 3 months, 6 months and 1 year after procedure was (54.9±13.8)%, (79.0±23.6)% and (106.9±25.1)% respectively. The preoperative complications were improved in some degree. There were no operative death, and anastomotic leak, anastomotic stenosis, or surgical site infection occurred. LSG is a safe and effective surgical technique, whose safety and efficacy may be increased by improving the perioperative management.

Intracorporeal esophagojejunostomy after laparoscopic total gastrectomy is technically difficult because this procedure should be performed in a narrow surgical field in the upper abdomen even when completely laparoscopic approaches are used. The placement of the anvil of a circular stapling device into the esophagus and connection the instrument to the anvil are extremely difficult steps in this surgery. Therefore, we developed a simple technique for intracorporeal esophagojejunostomy using hemi-double stapling technique; we named this technique the efficient purse-string stapling technique (EST). More recently, we have developed a modified EST (mEST) that utilizes a new stainless steel anvil rod instead of a plastic rod. Relative to the plastic rod, the steel rod is reusable and shorter; thus, it was easier to perform anvil placement into the esophagus with the steel rod. Anvil preparation for mEST: a stainless steel rod is attached to the shaft of the anvil, and the needle and thread are sutured to the tip of the rod. After complete insertion of the anvil into the esophageal cavity, the needle and thread are used to penetrate the anterior esophageal wall, and the esophagus is then clamped using a linear stapler just distal to the site penetrated by the thread. The linear stapler is fired, and anvil placement in the esophagus is simultaneously accomplished. After the rod is removed from the anvil, the instrument is intracorporeally connected to the anvil and then fired to complete the gastrojejunostomy. This technique is simple and facilitates intracorporeal reconstruction procedures in laparoscopic total gastrectomy. PMID:28815221

The authors aimed to compare the surgical performance and the short-term clinical outcomes of robotic assisted laparoscopic distal gastrectomy (RADG) with laparoscopy-assisted distal gastrectomy (LADG) in distal gastric cancer patients. From April 2009 to August 2010, 62 patients underwent LADG and 30 patients underwent RADG for preoperative stage I distal gastric cancer by one surgeon at the National Cancer Center, Korea. Surgical performance was measured using lymph node (LN) dissection time and number of retrieved LNs, which were viewed as surrogates of technical ease and oncologic quality. In clinicopathologic characteristics, mean age, depth of invasion and stage were significantly different between the LADG and RADG group. Mean dissection time at each LN station was greater in the RADG group, but no significant intergroup difference was found for numbers of retrieved LNs. Furthermore, proximal resection margins were smaller, and hospital costs were higher in the RADG group. In terms of the RADG learning curve, mean LN dissection time was smaller in the late RADG group (n = 15) than in the early RADG group (n = 15) for 4sb/4d, 5, 7-12a stations, but numbers of retrieved LNs per station were similar. With the exception of operating time and cost, the numbers of retrieved LNs and the short-term clinical outcomes of RADG were found to be comparable to those of LADG, despite the surgeon's familiarity with LADG and lack of RADG experience. Further studies are needed to evaluate objectively ergonomic comfort and to quantify the patient benefits conferred by robotic surgery. Copyright © 2011 Elsevier Ltd. All rights reserved.

This study was to examine the utility of a modified double-stapling end-to-end gastroduodenostomy method ('Tornado' anastomosis) compared to a method with an additional gastrotomy ('Anterior Incision' method) in laparoscopy-assisted distal gastrectomy. Forty-two patients with gastric cancer who underwent laparoscopy-assisted distal gastrectomy were analyzed retrospectively. Billroth-I using an additional gastrotomy was performed in 24 patients (AI group) and Billroth-I without an additional gastrotomy was performed in 18 (TOR group). Clinicopathological features, operative outcomes (lymph node dissection, operative time, operative blood loss) and postoperative outcomes (complications, postoperative hospital stay, and body weight loss at one year after surgery) were evaluated and compared between groups. Operative time was significantly shorter in the TOR group (251 min) than in the AI group (282 min) (p < 0.01). There were no statistically significant differences in operative blood loss, postoperative complications, and hospital stay between the 2 study groups. Body weight loss at one year after surgery was -5.8 kg in the TOR group and -6.5 kg in the AI group, without a statistically significant difference. Completion time for Billroth-I anastomosis was significantly shorter with Tornado anastomosis than with the Anterior Incision method, with safety equal between the two methods.

Here we report the method of anastomosis based on double stapling technique (hereinafter, DST) using a trans-oral anvil delivery system (EEATM OrVilTM) for reconstructing the esophagus and lifted jejunum following laparoscopic total gastrectomy or proximal gastric resection. As a basic technique, laparoscopic total gastrectomy employed Roux-en-Y reconstruction, laparoscopic proximal gastrectomy employed double tract reconstruction, and end-to-side anastomosis was used for the cut-off stump of the esophagus and lifted jejunum. We used EEATM OrVilTM as a device that permitted mechanical purse-string suture similarly to conventional EEA, and endo-Surgitie. After the gastric lymph node dissection, the esophagus was cut off using an automated stapler. EEATM OrVilTM was orally and slowly inserted from the valve tip, and a small hole was created at the tip of the obliquely cut-off stump with scissors to let the valve tip pass through. Yarn was cut to disconnect the anvil from a tube and the anvil head was retained in the esophagus. The end-Surgitie was inserted at the right subcostal margin, and after the looped-shaped thread was wrapped around the esophageal stump opening, assisting Maryland forceps inserted at the left subcostal and left abdomen were used to grasp the left and right esophageal stump. The surgeon inserted anvil grasping forceps into the right abdomen, and after grasping the esophagus with the forceps, tightened the end Surgitie, thereby completing the purse-string suture on the esophageal stump. The main unit of the automated stapler was inserted from the cut-off stump of the lifted jejunum, and a trocar was made to pass through. To prevent dropout of the small intestines from the automated stapler, the automated stapler and the lifted jejunum were fastened with silk thread, the abdomen was again inflated, and the lifted jejunum was led into the abdominal cavity. When it was confirmed that the automated stapler and center rod were made completely linear

Laparoscopic Sleeve Gastrectomy has become one of the most popular bariatric surgery types and helps treating not only obesity but also endocrinological diseases related to obesity. Therefore we aimed to evaluate the effects of laparoscopic sleeve gastrectomy on the treatment of type 2 diabetes. All patients, who underwent morbid obesity surgery during 2013-2014 and had a HbA1c >6 % were included in this prospective study. Demographical data, usage of oral antidiabetic drugs or insulin were recorded, and laboratory findings as HbA1c and fasting plasma glucose were evaluated preoperatively and postoperatively at the 6th and 12th months. Diabetes remission criteria were used to assess success of the surgical treatment. Totally 88 patients were included in this study. 55 patients were using oral antidiabetic drugs and 33 patients were using insulin. At the 6th month complete remission was observed in 80 (90.9 %), partial remission in 3 (3.4 %) and persistent diabetes in 5 (5.6 %) patients. At the 12th month complete remission was observed in 84 (95.4 %), partial remission in 1 (1.1 %) and persistent diabetes in 3 (3.4 %) patients. This study indicated that laparoscopic sleeve gastrectomy surgery achieved a complete remission of diabetes in 95.4 % patients having type 2 diabetes during a 1 year fallow up period. However, complete remission of type 2 diabetes has been reported as 80 % during long term fallow up in the literature. In our opinion this rate may change with longer follow up periods and studies involving more patients suffering type 2 diabetes.

To evaluate the safety and efficacy of totally laparoscopic total gastrectomy (TLTG) with esophagojejunostomy using a linear stapler compared with laparoscopic-assisted total gastrectomy (LATG) using a circular stapler in gastric cancer patients. We retrospectively reviewed 687 patients who underwent laparoscopic total gastrectomy for gastric cancer at a single institution from August 2008 to August 2014. The patients were divided into two groups according to the type of operation: 421 patients underwent TLTG and 266 underwent LATG. Clinicopathologic characteristics and surgical outcomes in the two groups were compared and analyzed. The TLTG group had higher mean ages at the time of operation (57.78 ± 11.20 years and 55.69 ± 11.96 years, P = 0.020) and more histories of abdominal surgery (20.2% and 12.4%, P = 0.008) compared with the LATG group. Surgical outcomes such as intraoperative and postoperative transfusions, combined operations, pain scores and administration of analgesics, and complications were similar between the two groups. However, compared with the LATG group, the TLTG group required a shorter operation time (149 min vs 170 min, P < 0.001), had lower postoperative hematocrit change (3.49% vs 4.04%, P = 0.002), less intraoperative events (3.1% vs 10.2%, P < 0.001), less intraoperative anastomosis events (2.4% vs 7.1%, P = 0.003), faster postoperative recovery such as median time to first flatus (3.30 d vs 3.60 d, P < 0.001), faster median commencement of soft diet (4.30 d vs 4.60 d, P < 0.001) and shorter length of postoperative hospital stay (6.75 d vs 7.02 d, P = 0.005). The intracorporeal method for reconstruction of esophagojejunostomy using a linear stapler may be considered a feasible procedure comparing with extracorporeal anastomosis using circular stapler because TLTG is simpler and more straightforward than LATG. Therefore, TLTG can be recommended as an appropriate procedure for gastric cancer.

Natural orifice specimen extraction - NOSE laparoscopy is a promising technique that avoids mini-laparotomy, possibly reducing postoperative pain, wound infections and hospital stay. Recent systematic reviews have shown that postoperative morbidity associated with laparoscopically assisted gastrectomies is similar to that after open gastrectomies. More specifically, there is no difference in wound infection rate. The study objective was to evaluate whether postoperative morbidity and hospital stay may be reduced by transoral specimen extraction after laparoscopically assisted gastrectomy for early gastric cancer (EGC). A prospective, nonrandomized study was carried out starting in August 2012. Data from all patients operated on during the first year, with minimum 18 months follow-up, were collected to assess feasibility, oncologic results, postoperative morbidity, hospital stay and functional results. Overall, 14 patients were included and followed-up. After gastric resection, a 3 cm opening was created on the gastric stump, and the specimen, divided into three segments stitched one to each other, was sutured to the gastric tube and retrieved through the mouth. Postoperative morbidity was 7.14% (1/14): one case of pneumonia. No wound infection occurred. The mean postoperative hospital stay was 4.7 ± 1.0 days. NOSE laparoscopic subtotal gastrectomy is feasible and safe, with similar oncologic results as LAG, but decreased morbidity and hospital stay.

Evaluate the efficacy of single-port sleeve gastrectomy (SPSG) and then compare it to a less-invasive sleeve approach (three-port) (3PSG) according to a propensity score (PS) matching analysis. We analyzed all patients who underwent SG through a three-port or a single-port laparoscopic approach. After 2 years, the follow-up was completed in 84% patients treated with 3PSG and 95% patients of the SPSG group. Excess weight loss (EWL) was comparable for the first year of follow-up within the two groups except for the controls at 3 months in which the SPSG group showed a higher EWL (p = 0.0243). We demonstrated the efficacy of SPSG in bariatric surgery even compared to another, less invasive, laparoscopic SG approach (three-port).

Obesity is one of the most rapidly increasing health problems in children. Laparoscopic sleeve gastrectomy (LSG) is one of the best treatment options and is feasible and safe in children. The aim of this study was to present the short-term results of a laparoscopic sleeve gastrectomy series in children. Children who underwent LSG in 2014-2017 were included in the study. Charts were investigated retrospectively and short-term weight loss was analyzed. Patients who had surgery in 2014-2017 were included in the study. There were six girls and two boys, and the median age was 15 years (range, 11-18 years). Mean weight was 159.25 ± 19.78 kg, and mean body mass index was 61.05 ± 8.5 kg/m 2 . Mean operation time was 70 min (range, 65-90 min), mean hospital stay was 5.1 days (range, 3-7 days), and mean follow up was 19.2 months (range, 1-43 months). Of these patients, five had hypertension and were under medication and two of these five also had hyperinsulinemia. One of the five children had Bardet-Biedl syndrome and one had bronchial asthma. After operation, medication was stopped in four of the eight children. At the time of writing, six patients were doing well without postoperative complications, or the need for reoperation. Even though the follow-up period was short and the number of patients was small, LSG was a feasible and promising surgical method for morbidly obese children. A multidisciplinary approach and lifelong behavior therapy are key steps for success. © 2018 Japan Pediatric Society.

Our objective was to assess the risk factors for surgical site infections (SSIs) in gastric surgery using the results of the Osaka Gastrointestinal Cancer Chemotherapy Study Group (OGSG) 0501 phase 3 trial. The OGSG 0501 trial was conducted to compare standard prophylactic antibiotic administration versus extended prophylactic antibiotic administration in 355 patients who underwent open distal gastrectomy for gastric cancer. Various risk factors associated with the incidence of SSI following gastrectomy were analyzed from the results of this multi-institutional randomized controlled trial. Among the 355 patients, there were 24 SSIs, for an overall SSI rate of 7 %. Multivariate analysis using eight baseline factors (administration of antibiotics, age, sex, body mass index [BMI], prognostic nutritional index, tumor stage, lymph node dissection, reconstructive method) identified that BMI ≥ 25 kg/m(2) was an independent risk factor for the occurrence of SSI (odds ratio 2.82; 95 % confidence interval [CI] 1.05-7.52; P = 0.049). BMI also showed significant relationships with the volume of blood loss and the operation time (P = 0.001 and P < 0.001, respectively). Compared with patients of normal weight, overweight patients had a significantly higher risk of SSI after distal gastrectomy for cancer.

Uncut Roux-en-Y gastrojejunostomy is a modification of the Billroth II procedure with Braun anastomosis, in which a jejunal occlusion is fashioned to avoid the Roux Stasis Syndrome. This review aimed to summarize the current knowledge about the uncut Roux-en-Y anastomosis operation, so that surgeons may be able to make informed decisions about its clinical application. Additionally, we hope that our findings will guide future research on this topic. Areas covered: The original uncut technique was associated with dehiscence or recanalization of the jejunal occlusion, and was therefore not widely applied. However, with recent improvements in the method of jejunal occlusion, the uncut Roux-en-Y reconstruction may be an appropriate alternative for digestive tract reconstruction after distal gastrectomy. This review summarizes the basic research on and clinical applications of uncut Roux-en-Y gastrojejunostomy from the following several aspects: origin of the uncut reconstruction technique, rationale for uncut reconstruction based on data from animal experiments, clinical results of the uncut reconstruction, recanalization and its countermeasures, and so on. Expert commentary: The uncut Roux-en-Y gastrojejunostomy is a controversial yet promising method of gastrointestinal reconstruction after distal gastrectomy. Prospective randomized controlled trials and long-term follow-up outcomes are required to support the modified technique in the future.

Robotic surgery is a new technique with the benefits of a 3-dimensional view, the ability to use multidegree-of-freedom forceps, the elimination of physiological tremors, and a stable camera view. The aim of this study was to evaluate the feasibility and short-term outcomes of robotic surgery for gastric cancer, compared with conventional laparoscopic surgery. A literature search was performed for comparative studies reporting perioperative outcomes of robotic gastrectomy (RG) and laparoscopic gastrectomy (LG). The methodological quality of the selected studies was assessed. The data were analyzed using Stata (Version 13.0) software. Eleven studies of 3503 patients totally were included for meta-analysis. Compared with LG, RG indicated potentially favorable outcomes in terms of blood loss [weighted mean difference (WMD)=-36.50; 95% confidence interval (CI), -61.39 to -11.61], and time to oral intake (WMD=-0.28; 95% CI, -0.46 to -0.09). But RG suggested longer operative time (WMD=53.48; 95% CI, 38.84-68.12). There were no differences in terms of postoperative flatus, length of hospital stay, postoperative complications, and lymph nodes harvested (P>0.05). RG for the treatment of gastric cancer is a feasible and safe procedure in the hand of experienced laparoscopic surgeons. But the long-term outcomes between the 2 techniques need to be further examined.

Total or proximal gastrectomy is usually performed for early proximal gastric carcinoma, but the optimal type of gastrectomy is still unknown. We evaluated short-term outcomes and nutritional status after laparoscopic subtotal gastrectomy (LsTG) in comparison with laparoscopic total gastrectomy (LTG) and laparoscopic proximal gastrectomy (LPG). We analyzed 113 patients who underwent LsTG (n = 38), LTG (n = 48), or LPG (n = 27) for cStage I gastric cancer located in the upper third of the stomach. Postoperative morbidities, nutritional status including body weight, serum albumin, hemoglobin, the prognostic nutritional index (PNI), and endoscopic findings at 1 year after surgery were compared between LsTG and both LTG and LPG. Operation time and intraoperative blood loss were similar among the three groups. The incidence of postoperative morbidities was lower in LsTG than in LTG. The degree of body weight loss was significantly smaller in LsTG than in LTG at 6 and 12 months. At 12 months, LsTG resulted in better serum albumin and PNI than LPG, and better hemoglobin than LTG. Endoscopic examination demonstrated that one LsTG patient and two LPG patients had reflux esophagitis. Remnant gastritis was observed more frequently in LPG than in LsTG. No LsTG patient had bile reflux, although it was observed in four LPG patients. LsTG with a very small remnant stomach had favorable short-term outcomes and nutritional status compared with LTG and LPG, so it may be a better treatment option for cStage I proximal gastric carcinoma.

To explore the feasibility of subserosal injection of carbon nanoparticle via venous infusion needle to label lymph node and its application value in laparoscopic radical gastrectomy. Forty patients with gastric cancer were randomly divided into two groups (carbon nanoparticle group and control group). Subserosal injection of carbon nanoparticle around the tumor was performed via venous infusion needle laparoscopically at the beginning of surgery in carbon nanoparticles group, while the patients routinely underwent laparoscopic radical gastrectomy in control group. Results of harvested lymph nodes were compared between the two groups. The perioperative complications and the side effect of carbon nanoparticle were also evaluated. The average number of harvested lymph node in carbon nanoparticle group (31.7±7.6) was significantly higher than that in control group (19.8±6.1, P<0.05). The proportion of harvested small node (< 5 mm) in carbon nanoparticles group(61.0%) was higher than that in control group(43.3%, P<0.01). The mean harvest time in carbon nanoparticle group [(23.5±4.8) min] was shorter than that in control group [(32.6±5.5) min, P<0.05]. The rate of black-dyed harvested lymph node was 61.9% and the metastasis rate of black-dyed lymph node was 23.0% in carbon nanoparticle group, which were significantly higher than those without black-dyed(6.2%, P<0.05) and those in control group (15.7%, P<0.05). The operative time and perioperative complications were not significantly different between the two groups, and no serious side effect caused by carbon nanoparticle was observed. Subserosal injection of carbon nanoparticle via venous infusion needle to label lymph nodes during laparoscopic radical gastrectomy is safe and feasible. It can increase the number of harvested lymph node, especially the small node.

The impact of operative technique on outcomes in laparoscopic sleeve gastrectomy has been explored previously; however, the relative importance of patient characteristics remains unknown. Our aim was to characterize national variability in operative technique for laparoscopic sleeve gastrectomy and determine whether patient-specific factors are more critical to predicting outcomes. We queried the database of the Metabolic and Bariatric Surgery Accreditation and Quality Improvement Program for laparoscopic sleeve gastrostomies performed in 2015 (n = 88,845). Logistic regression models were used to determine predictors of postoperative outcomes. In 2015, >460 variations of laparoscopic sleeve gastrectomy were performed based on combinations of bougie size, distance from the pylorus, use of staple line reinforcement, and oversewing of the staple line. Despite such substantial variability, technique variants were not predictive of outcomes, including perioperative morbidity, leak, or bleeding (all P ≥ .05). Instead, preoperative patient characteristics were found to be more predictive of these outcomes after laparoscopic sleeve gastrectomy. Only history of gastroesophageal disease (odds ratio 1.44, 95% confidence interval 1.08-1.91, P < .01) was associated with leak. Considerable variability exists in technique among surgeons nationally, but patient characteristics are more predictive of adverse outcomes after laparoscopic sleeve gastrectomy. Bundled payments and reimbursement policies should account for patient-specific factors in addition to current accreditation and volume thresholds when deciding risk-adjustment strategies.

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

The feasibility, safety, and improved quality of postoperative life following laparoscopy-assisted pylorus-preserving gastrectomy (LAPPG) with a hand-sewn anastomosis via a mini-laparotomy for early gastric cancer (EGC) have been previously established. Here we describe the surgical procedure of totally laparoscopic pylorus-preserving gastrectomy (TLPPG) using an intracorporeal delta-shaped anastomosis technique, and the short-term surgical outcomes of 60 patients with EGC in the middle stomach are reported. After lymphadenectomy and mobilization of the stomach, intraoperative gastroscopy was performed in order to verify the location of the tumor, and then the distal and proximal transecting lines were established, 5 cm from the pyloric ring and just proximal to Demel's line, respectively. Following transection of the stomach, a delta-shaped intracorporeal gastrogastrostomy was made with linear staplers. There were no intraoperative complications or conversions to open surgery. Mean operation time and blood loss were 259 min and 28 mL, respectively. Twelve patients (20.0%) experienced postoperative complications classified as grade II using the Clavien-Dindo classification, with the most frequent complication being gastric stasis (6 cases, 10.0 %). The incidence of severe complications classified as grade III or above was 1.7%; only one patient required reoperation and intensive care due to postoperative intraabdominal bleeding and subsequent multiple organ failure. TLPPG with an intracorporeal delta-shaped anastomosis was found to be a safe procedure, although it tended to require a longer operating time than the well-established LAPPG with a hand-sewn gastrogastrostomy.

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

Since its widespread acceptance for the treatment of early gastric cancer, laparoscopic gastrectomy has been gaining popularity as a treatment option for advanced gastric cancer. However, laparoscopic total gastrectomy (LTG) with splenectomy is seldom performed, because of its difficulty of removal of station 10 lymph nodes; splenectomy is technically essential for complete removal of these lymph nodes. The purpose of this study was to describe the details of the LTG procedure and to evaluate the short- and long-term outcomes of LTG with splenectomy. Of 725 consecutive patients with gastric cancer who underwent laparoscopic gastrectomy with lymph node dissection in our institution from January 1996 to December 2012, 18 consecutive patients who underwent LTG with splenectomy were enrolled in this study. No operative mortality occurred, and the pathological margins were free from cancer cells in all patients. The mean operation time was 388 min (range 324-566 min). The mean volume of blood loss was 45 ml (range 5-347 ml), and the mean number of dissected lymph nodes was 51 (range 40-105). Postoperative morbidity occurred in six patients (33.3%) (each with grade B postoperative pancreatic fistula, postoperative bleeding, chylous ascites, atelectasis, ileus, and intra-abdominal infection). Five patients (27.8%) developed recurrence (four in the peritoneum and one in the liver), and the overall 3- and 5-year survival rates were 83.0 and 72.6%, respectively. Considering the 0% mortality rate and low rates of postoperative morbidity and locoregional recurrence, LTG with splenectomy is technically and oncologically acceptable. This procedure can be expanded to include advanced gastric cancer, which generally requires splenectomy for lymph node dissection.

Patients' quality of life (QoL) deteriorates remarkably after gastrectomy. Billroth I reconstruction following distal gastrectomy has the physiological advantage of allowing food to pass through the duodenum. It was hypothesized that Billroth I reconstruction would be superior to Roux-en-Y reconstruction in terms of long-term QoL after distal gastrectomy. This study compared two reconstructions in a multicentre prospective randomized clinical trial to identify the optimal reconstruction procedure. Between January 2009 and September 2010, patients who underwent gastrectomy for gastric cancer were randomized during surgery to Billroth I or Roux-en-Y reconstruction. The primary endpoint was assessment of QoL using the Functional Assessment of Cancer Therapy - Gastric (FACT-Ga) questionnaire 36 months after surgery. A total of 122 patients were enrolled in the study, 60 to Billroth I and 62 to Roux-en-Y reconstruction. There were no differences between the two groups in terms of postoperative complications or mortality, and no significant differences in FACT-Ga total score (P = 0·496). Symptom scales such as epigastric fullness (heaviness), diarrhoea and fatigue were significantly better in the Billroth I group at 36 months after gastrectomy (heaviness, P = 0·040; diarrhoea, P = 0·046; fatigue, P = 0·029). The rate of weight loss in the third year was lower for patients in the Billroth I group (P = 0·046). The choice of anastomotic reconstruction after distal gastrectomy resulted in no difference in long-term QoL in patients with gastric cancer.

Esophagojejunal anastomosis fistula is the main complication after a total gastrectomy. To avoid a complex procedure on friable inflamed perianastomotic tissues, a coated self-expandable stent is mounted at the site of the anastomotic leak. A complication of stenting procedure is that it might lead to distal esophageal stenosis. However, another frequently encountered complication of stenting is stent migration, which is treated nonsurgically. When the migrated stent creates life threatening complications, surgical removal is indicated. We present a case of a 67-year-old male patient who was treated at our facility for a gastric adenocarcinoma which developed, postoperatively, an esophagojejunostomy fistula, a distal esophageal stenosis, and a metallic coated self-expandable stent migration. To our knowledge, this is the first reported case of an esophagojejunostomy fistula combined with a distal esophageal stenosis as well as with a metallic coated self-expandable stent migration.

Bariatric surgery is the most effective treatment for severe obesity, capable of producing more than 50% excess weight loss at 10-year follow-up (James Clin Dermatol 1; 22:276-80; O'Brien Br J Surg 2; 102:611-17; Buchwald et al. Metab Syndr 3; 347-56). The success of bariatric surgery extends far beyond weight loss, with up to 80-90% of patients having improvement or resolution of many of their weight-related co-morbidities including type II diabetes mellitus and hypertension (Puzziferri et al. JAMA 4; 312:934-42; Buchwald et al. Am J Med 5; 122:248-56). However, there is a paucity of data regarding conversional bariatric surgery. This study aims to explore the efficacy, safety and feasibility of conversional surgery. This study represents the largest Australasian series focusing on conversional bariatric surgery. The study was conducted in the Norwest Private Hospital and Hospital for Specialist Surgery (HSS), both private Hospitals in Sydney, Australia. Data was collected prospectively at regular intervals for more than 12 months from 1 January 2012 to 1st November 2015 for all patients requiring a laparoscopic sleeve gastrectomy (LSG) as secondary procedure after prior laparoscopic adjustable gastric band (LAGB). Excess weight loss (EWL), percentage total body weight loss (TWL) and excess BMI loss (EBMIL) as well as any complications were recorded. There were low rates of morbidity (1.1%) and no mortality at 12-month follow-up. Satisfactory EWL of 60% (95% CI: 56.6-63.4%), EBMIL of 60.1% (95% CI: 48.8-71.4%) and 16% TWL was achieved at 12-month follow-up. We therefore conclude that sleeve gastrectomy is a safe and valid option for conversional bariatric surgery following LAGB.

Intra-thoracic Sleeve Migration (ITSM): an Underreported Phenomenon After Laparoscopic Sleeve Gastrectomy.

Despite its technical simplicity, laparoscopic sleeve gastrectomy (LSG) complications are increasingly reported. Intra-thoracic sleeve migration (ITSM ) is a rare complication after LSG which has been inconsistently addressed in the literature. The purpose of this study was to emphasize ITSM occurrence after LSG and evaluate the perioperative factors associated with its development. Between January and July 2016, LSG patients diagnosed with ITSM at two bariatric surgery departments were identified. Perioperative factors were assessed for all the patients and compared between two groups, LSG alone and LSG with concomitant hiatal hernia (HH) repair (HHR). A total of 19 patients (6 males and 13 females) were included. Central obesity was present in 18 patients (94.7%). Nine patients (47.4%) had concomitant hiatal hernia repair during their original LSG. Post-LSG GERD (94.7%) (38.9% de novo and 61.1% recurrent) and post-LSG constipation (57.9%) were commonly associated with ITSM. Severe refractory GERD was the most common presentation for ITSM (94.7%), followed by epigastric pain (47.4%), persistent nausea/vomiting (36.8%), and dysphagia (21.1%). Time interval between primary LSG and ITSM diagnosis ranged from 1 day to 3 years. Patients with LSG and concomitant HHR presented with higher post-LSG BMI compared to the LSG patients (37 ± 6.4 kg/m 2 vs. 30.1 ± 6.3 kg/m 2 , p = 0.03). All the patients underwent successful reduction of ITSM and subsequent HHR. Central obesity, chronic constipation, post-LSG GERD, and concomitant HHR are commonly seen in post-laparoscopic sleeve gastrectomy intra-thoracic sleeve migration.

We compared laparoscopic and robotic gastrectomies with open gastrectomies and with each other that were held for gastric cancer in Europe. We searched for studies conducted in Europe and published up to 20 February 2015 in the PubMed database that compared laparoscopic or robotic with open gastrectomies for gastric cancer and with each other. We found 18 original studies (laparoscopic vs open: 13; robotic vs open: 3; laparoscopic vs robotic: 2). Of these, 17 were non-randomized trials and only 1 was a randomized controlled trial. Only four studies had more than 50 patients in each arm. No significant differences were detected between minimally invasive and open approaches regarding the number of retrieved lymph nodes, anastomotic leakage, duodenal stump leakage, anastomotic stenosis, postoperative bleeding, reoperation rates, and intraoperative/postoperative mortality. Nevertheless, laparoscopic procedures provided higher overall morbidity rates when compared with open ones, but robotic approaches did not differ from open ones. On the contrary, blood loss was less and hospital stay was shorter in minimally invasive than in open approaches. However, the results were controversial concerning the duration of operations when comparing minimally invasive with open gastrectomies. Additionally, laparoscopic and robotic procedures provided equivalent results regarding resection margins, duodenal stump leakage, postoperative bleeding, intraoperative/postoperative mortality, and length of hospital stay. On the contrary, robotic operations had less blood loss, but lasted longer than laparoscopic ones. Finally, there were relatively low conversion rates in laparoscopic (0%-6.7%) and robotic gastrectomies (0%-5.6%) in most studies. Laparoscopic and robotic gastrectomies may be considered alternative approaches to open gastrectomies for treating gastric cancer. Minimally invasive operations are characterized by less blood loss and shorter hospital stay than open ones. In

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

Subtotal gastrectomy for gastric cancer

Although a steady decline in the incidence and mortality rates of gastric carcinoma has been observed in the last century worldwide, the absolute number of new cases/year is increasing because of the aging of the population. So far, surgical resection with curative intent has been the only treatment providing hope for cure; therefore, gastric cancer surgery has become a specialized field in digestive surgery. Gastrectomy with lymph node (LN) dissection for cancer patients remains a challenging procedure which requires skilled, well-trained surgeons who are very familiar with the fast-evolving oncological principles of gastric cancer surgery. As a matter of fact, the extent of gastric resection and LN dissection depends on the size of the disease and gastric cancer surgery has become a patient and “disease-tailored” surgery, ranging from endoscopic resection to laparoscopic assisted gastrectomy and conventional extended multivisceral resections. LN metastases are the most important prognostic factor in patients that undergo curative resection. LN dissection remains the most challenging part of the operation due to the location of LN stations around major retroperitoneal vessels and adjacent organs, which are not routinely included in the resected specimen and need to be preserved in order to avoid dangerous intra- and postoperative complications. Hence, the surgeon is the most important non-TMN prognostic factor in gastric cancer. Subtotal gastrectomy is the treatment of choice for middle and distal-third gastric cancer as it provides similar survival rates and better functional outcome compared to total gastrectomy, especially in early-stage disease with favorable prognosis. Nonetheless, the resection range for middle-third gastric cancer cases and the extent of LN dissection at early stages remains controversial. Due to the necessity of a more extended procedure at advanced stages and the trend for more conservative treatments in early gastric cancer, the

Laparoscopic sleeve gastrectomy (LSG) is becoming an increasingly popular form of bariatric surgery, accounting for more than 50% of these procedures performed in the USA. Given this popularity, more is being understood about the complications associated with LSG, which, though uncommon, include the formation of strictures and stenosis. The purpose of this study is to establish a safe and effective protocol for the treatment of stenosis post-LSG using endoscopic balloon dilatation. This is a prospective review of 26 patients who had undergone LSG in Kuwait, followed by sleeve gastrectomy stenosis (SGS) and were then referred to Amiri Hospital for endoscopic balloon dilatation from October 2008 up to June 2016. A total of 26 patients (four males; 22 females) presented with symptoms of stenosis post-LSG during the study period. The mean age of the patients was 34.6 ± 10.8 years. The mean body mass index at the time of surgery was 43 ± 1.6 kg/m 2 . The median interval from the initial LSG surgery was 95 days. Nine patients had an early presentation (≤3 months from surgery), while 17 presented late (>3 months). The patients were followed for a mean duration of 156 ± 20 days from the last endoscopic balloon dilatation. A total of 23 (88.5%) patients had complete resolution of their symptoms. Adverse events were observed in one patients, who was removed from the study. Gastric stenosis is a rare but potentially serious complication of LSG. Serial dilatation of SGS employing endoscopic balloons is a safe method of treatment, with high efficacy rates. This new method may offer a less invasive alternative to surgical revision. However, if endoscopic treatment fails, surgery is necessary.

Though laparoscopic distal pancreatectomy for benign conditions was first described in the early 1990s, it has not become as popular as other laparoscopic surgeries. Published literature on this topic consists of several case reports and a handful of small series. We present our experience, which, to the best of our knowledge, is the largest series reported to date. Since 1998, 22 patients have undergone distal pancreatectomy at our institute. The technique of distal pancreatosplenectomy, as well as spleen-preserving distal pancreatectomy, is described. Four males and 18 females in the age range of 12-69 years underwent operation. Splenic preservation was possible in 7 patients. The tumor diameter ranged from 2.1 cm to 7.4 cm. The mean operating time was 215 min. The mean length of incision required for specimen retrieval was 3.4 cm. All patients were started on a liquid diet on the first postoperative day. The median hospital stay was 4 days. One patient developed a pancreatic fistula that was managed conservatively. At the end of an average follow-up of 4.6 years, no recurrence has been reported. Laparoscopic distal pancreatectomy is a safe procedure, with minimal morbidity, rapid recovery, and short hospital stay. In appropriate cases, splenic preservation is feasible.

Laparoscopic approach is the gold standard for surgical treatment of morbid obesity. The single-port (SP) approach has been demonstrated to be a safe and effective technique for the treatment of morbid obesity in several case control studies. Compare conventional multiport laparoscopy (LAP) with an SP approach for the treatment of morbid obesity using sleeve gastrectomy in terms of postoperative pain using a visual analog scale (VAS) 0-100, surgical outcome, weight loss, and aesthetical satisfaction at 6 months after surgery. University Hospital, Spain. Randomized, controlled pilot study. The trial enrolled patients suitable for bariatric surgery, with a body mass index lower than 50 kg/m 2 and xiphoumbilical distance lower than 25 cm. Patients were randomly assigned to receive LAP or SP sleeve gastrectomy. A total of 30 patients were enrolled; 15 were assigned to LAP group and 15 to SP group. No patients were lost during follow-up. Baseline characteristics were similar in both groups. A significantly higher level of pain during movement was noted for the patients in the LAP group on the first (mean VAS 49.3±12.2 versus 34.1±8.9, P = .046) and second days (mean VAS 35.9±10.2 versus 22.1±7.9, P = .044) but not the third day (mean VAS 20.1±5.2 versus 34.12.9 ±4.3, P = .620). No differences regarding pain at rest, operative time, complications, or weight loss at 6 months were observed. Higher aesthetical satisfaction was noticed in SP group. In selected patients, SP surgery presented less postoperative pain in sleeve gastrectomy compared with the conventional laparoscopic approach with similar surgical results.

Laparoscopic sleeve gastrectomy evolved as a primary bariatric procedure with little information on its nutritional effects. Our objective was to assess the longer term micronutrient and vitamin status after laparoscopic sleeve gastrectomy at a university hospital. Measurements of ferritin, iron, total iron binding capacity, hemoglobin, hematocrit, parathyroid hormone, albumin, calcium, magnesium, phosphorus, zinc, folate, and vitamins A, B1, B12, and D were obtained at baseline and 1, 3, and 5 years after surgery. Two-sample t tests with multiple adjusted comparisons and Fisher's exact test were used to determine deficiency. A total of 82 patients (67% women), with a mean age of 46.4 years and a baseline body mass index 55.7 kg/m2 were included in the present study (35 at 1, 27 at 3, and 30 at 5 years postoperatively). The percentage of excess body mass index loss was 58.5% at year 1 in 35 patients, 63.1% at year 3 in 27 patients, and 46.1% at year 5 in 30 patients. The parathyroid hormone level decreased from 75.0 to 49.6 ng/mL in year 1 to 40.7 ng/mL in year 3. The year 5 levels increased to 99.6 ng/mL. The mean vitamin D level increased from 23.6 ng/mL to 35.0, 32.1 and 34.8 at years 1, 3, and 5 (P = .05 for baseline to year 1). The vitamin D level was less than normal in 42% of the patients at year 5. After normalization from baseline, by year 5, parathyroid hormone had increased in 58.3% of patients. At year 5, vitamin B1 was less than normal in 30.8% of patients, and hemoglobin and hematocrit were less than normal in for 28.6% and 25% of patients, respectively. Finally, 28.9% of patients reported taking supplements in year 1, 42.9% in year 3, and 63.3% in year 5. The other variables were not significantly different. Laparoscopic sleeve gastrectomy resulted in health improvements through year 3. At year 5, the nutrient levels had reverted toward the baseline values. These observations provide focus for necessary clinical monitoring. Copyright © 2012 American

Laparoscopic sleeve gastrectomy (LSG) is a commonly performed bariatric procedure. Although bariatric surgery is becoming increasingly recognized as a treatment option for diabetes, there remain concerns about the operative risks faced by diabetic patients. This study's objective was to determine the safety of bariatric surgery in diabetic patients, specifically the type 2 diabetic (T2DM) population. Patients over 18 years of age with a body mass index (BMI) ≥ 35 kg/m 2 who underwent LSG in 2012 in the ACS-NSQIP database were identified. Emergency cases were excluded from analysis. Data included patient demographics, comorbidities, length of stay, and 30-day complications. The primary outcome was 30-day overall complication rate, and secondary outcomes included major complications and reoperation rates. There were 6399 LSG in the NSQIP database in 2012. Three hundred and twenty-two patients were excluded for BMI < 35, and 15 cases were deemed emergencies and excluded. Of the 6062 LSG who met the study criteria, 4726 (78 %) of patients were non-diabetic, 941 (15.5 %) had T2DM, and 395 (6.5 %) had T1DM. T2DM patients were more likely to be male (28.9 vs. 19.3 %, p < 0.001), were older (47.6 years vs. 42.5 years, p < 0.001), and had a higher BMI (46.4 vs. 45.7 kg/m 2 , p = 0.027) compared with non-diabetics. The overall 30-day complication rate did not differ between groups (6.5 % T2DM vs. 5.6 % non-diabetic, p = 0.292). After controlling for possible confounders, T2DM remained at no increased risk of 30-day complications (OR 1.16, 95 % CI 0.87-1.55, p = 0.301). In sub-analyses of specific complications, T2DM had a slightly higher rate of blood transfusions (1.8 vs. 1.0 %, p = 0.037). Other postoperative complications did not differ between groups. The 30-day complication rate for type 1 diabetics was greater than for T2DM (9.9 vs. 6.5 %, p = 0.031) and non-diabetics (9.9 vs. 5.6 %, p < 0.001). Laparoscopic sleeve gastrectomy is a

The adoption of laparoscopy for distal pancreatectomy has proven to substantially improve short-term outcomes. Stress response after major surgery can be further minimized within an enhanced recovery programme (ERP). However, data on the potential benefit of an ERP for laparoscopic distal pancreatectomy are still lacking. The aim was to assess the feasibility, safety and cost of ERP for patients undergoing laparoscopic distal pancreatectomy. This is a case-control study from a Tertiary University Hospital. Sixty-six consecutive patients who underwent laparoscopic distal pancreatectomy were analyzed. Twenty-two patients were enrolled for the ERP and compared with previous consecutive 44 patients managed traditionally (1:2 ratio). Operative details, post-operative outcome and cost analysis were compared in the two groups. Patients enrolled in the ERP had similar intraoperative blood loss (median 165 ml vs. 200 ml; p = 0.176), operation time (225 min vs. 210 min; p = 0.633), time to remove naso-gastric tube (1 vs. 1 day; p = 0.081) but significantly shorter time to mobilization (median 1 vs. 2 days; p = 0.0001), start solid diet (2 vs. 3 days; p = 0004), and pass stools (3 vs. 5 days; p = 0.002) compared to the control group. Median length of stay was significantly shorter in the ERP group (3 vs. 6 days; p < 0.0001). No significant difference in readmission or complication rate was observed. Cost analysis was significantly in favor of the ERP group (p = 0.0004). Implementation of ERP optimizes outcomes for laparoscopic distal pancreatectomy with significant earlier return to normal gut function, reduced length of stay and cost saving.

2016-04-01

In kidney transplantation, obesity is associated with poorer graft survival and patient survival. Bariatric surgery may provide benefit for these patients, not only by inducing weight loss, but also via reduction of diabetes. We report a case of morbid obesity, poorly controlled new-onset diabetes mellitus, and gout after kidney transplantation that was treated with laparoscopic sleeve gastrectomy 3 years after kidney transplantation. After 1 year of follow-up, 76% excessive body weight loss was attained. No complications were noted. The operation also provided total remission of diabetes and gout as well as good graft survival. Based on our experience, laparoscopic sleeve gastrectomy may be a feasible treatment for obese patients after renal transplantation to help resolve obesity and control new-onset diabetes. However, the timing of operation and the long-term potential for graft and patient survivals with this operation require further study. Copyright © 2016 Elsevier Inc. All rights reserved.

Spleen-preservation has recently been emphasized in benign and borderline malignant pancreatic diseases requiring distal pancreatectomy. Reports to suggest that laparoscopic distal pancreatectomy is feasible and safe have been increasingly published. Robotic surgical system has been introduced and is expected to provide unique advantages in laparoscopic surgery. However, robot-assisted pancreatic surgery has not yet been performed by many surgeons. A 45-year-old female patient with abdominal discomfort was found to have pancreatic cyst in the body of the pancreas. Mucinous cystic tumor of the pancreas was the most favourable preoperative diagnosis. She underwent spleen-preserving laparoscopic distal pancreatectomy by using da Vinci surgical robot system. Splenic artery and vein were so tightly adherent to the pancreatic cyst that segmental resection of splenic vessels was required. Postoperative course was uneventful. She was able to come home in 5 days after surgery. Postoperative follow up color doppler ultrasound scan, taken on 2 weeks after surgery, showed minimal fluid collection around surgical field and no evidence of splenic infarction with good preservation of splenic perfusion. Robot-assisted spleen preserving distal pancreatectomy is thought to be feasible and safe. Several unique advantages of robotic system are expected to enhance safer and more precise surgical performance in near future. More experiences are mandatory to confirm real benefit of robot surgery in pancreatic disease.

The effect of sleeve gastrectomy (SG) on the prevalence of gastroesophageal reflux disease (GERD) remains unclear. We aimed to outline the currently available literature. All relevant databases were searched for publications examining the effect of laparoscopic SG on GERD. Primary outcome measure was change in prevalence of GERD symptoms, antireflux medication use, and esophageal function tests. Secondary outcomes were prevalence of new-onset GERD and esophagitis. Thirty-three articles were included. Eleven studies used questionnaires to assess changes in the prevalence of GERD symptoms, with a risk difference in prevalence of 4.3%. Eight studies used esophageal function tests, with paradoxical results. Pooled incidence of new-onset GERD symptoms was 20%, with a strong suggestion of heterogeneity. New-onset esophagitis ranged from 6.3% to 63.3%. Because of high heterogeneity among available studies and paradoxical outcomes of objective esophageal function tests, the exact effect of laparoscopic SG on the prevalence of GERD remains unanswered. Surgeons should carefully evaluate preoperative GERD symptoms when choosing the proper bariatric technique. Copyright © 2016 Elsevier Inc. All rights reserved.

The conventional Billroth I anastomosis (cBIA) after laparoscopic distal gastrectomy (LDG) is performed through circular staple extracorporeally. Now, delta-shaped anastomosis (DA), which is performed using a linear stapler intracorporeally, becomes popular. We conducted a meta-analysis to compare the effectiveness and safety between the 2 techniques. A systematic literature search was performed using PubMed, Ovid, and the Cochrane Library Central. Participants of any age and sex, who underwent DA, or cBIA after LDG, were considered following inclusion criteria. A total of 11 articles, published between 2010 and 2017, fulfilled the selection criteria. The total sample size of these studies was 2729 cases, including DA group 1008 cases and cBIA group 1721 cases. Compared to cBIA group, patients in DA group had less blood loss (mean deviation [MD] = -0.68, 95% confidence interval [CI] = -0.15 to -0.31, P < .001), fewer administration of analgesics (MD = -0.82, 95% CI = -1.58 to -0.05, P = .04), lower NRS score on POD 1 (MD = -0.84, 95% CI = -1.34 to -0.33, P = .001), lower NRS score on POD 3 (MD = -0.38, 95% CI = -0.50 to -0.26, P < .001). Furthermore, compared to cBIA group, obese patients in DA group had fewer total number of complications (MD = 0.46, 95% CI = 0.22 to 0.95, P = .04), shorter postoperative hospital stays (MD = -0.73, 95% CI = -1.18 to -0.28, P = .001), earlier first flatus (MD = -0.30, 95% CI = -0.50 to -0.10, P = .004), fewer administration of analgesics (MD = -1.08, 95% CI = -1.61 to -0.55, P < .001), lower NRS score on POD 1 (MD = -0.68, 95% CI = -0.99 to -0.37, P < .001) and lower NRS score on POD 3 (MD = -0.63, 95% CI = -0.86 to -0.40, P < .001). Compared with cBIA, DA is a safe and feasible procedure, with similar surgical outcomes and postoperative complications. In terms of postoperative recovery, DA is less invasive with quicker resume than cBIA, especially for the obese patients.

Gastroesophageal reflux disease (GERD) and/or hiatus hernia (HH) are one of the most common disorders of the upper gastrointestinal tract. Despite the positive effect of sleeve gastrectomy (SG) regarding weight loss and improvement in obesity co-morbidities, there are concerns about the development of de novo gastroesophageal reflux disease or worsening the existing GERD after this bariatric operation. Furthermore, controversy exists on the consequences of SG in lower esophageal sphincter function and about the ideal procedure when a hiatus hernia is preoperatively diagnosed or discovered during the laparoscopic SG. This review systematically investigates the incidence, the pathophysiology of GERD and/or HH in morbidly obese individuals before and after SG, and the treatment options for concomitant HH repair during laparoscopic sleeve gastrectomy.

Bleeding and staple-line leak, are the most common complications of laparoscopic sleeve gastrectomy. To decrease the incidence of this complications, a variety of intraoperative reinforcement of staple line is used. Reinforced GIA™ is a new automatic suture device with pre-attached synthetic tissue reinforcement, but no study has evaluated its use in sleeve gastrectomy. The objective of this study is to evaluate the efficacy and safety of this new staple line reinforcement technique in laparoscopic sleeve gastrectomy. We conducted a retrospective review of 290 patients who underwent laparoscopic sleeve gastrectomy between January 2013 and January 2016 in which reinforced GIA™ or standard GIA™ was used. Patients preoperative characteristics, Operative time, staple line leaks, staple line bleeds, stenosis, and complications requiring reoperation were collected. A total of 187 laparoscopic sleeve gastrectomy were performed with standard GIA and 103 with reinforced GIA™. Patient characteristics were not significantly different between the groups. The average operating time in the standard GIA group is 57.41±16.44 min against 50.9±14.12 min in the reinforced GIA group (P=0.006). Two staple line leaks developed in the standard GIA group and reoperated against no patients in the reinforced GIA group, without significant difference between the both groups (P=0.66). Staple line bleeds are less in the reinforced GIA group, only 23 (22.3%) against 78 (41.7%) cases in the standard GIA group (P=0.001). No patients of both groups developed gastric sleeve stenosis. During laparoscopic sleeve gastrectomy, the use of a reinforced stapler significantly reduces the operative time and staple line bleeding. No significant difference is evidenced in terms of reduction of staple line leaks with this reinforced stapler.

Although stapler dissection and closure is commonly used for laparoscopic distal pancreatectomy (LDP), it is risky in patients with thick pancreatic parenchyma or titanium allergy. We performed laparoscopic pancreatic parenchymal dissection with cavitron ultrasonic surgical aspirator (CUSA) successfully in a patient with titanium allergy. Slinging the pancreas with nylon tape delineates the surgical plane. Pancreatic parenchyma was transected by CUSA in an almost bloodless field. Pancreatic duct branches and vessels were adequately exposed and dissected with a vessel sealing system. The main pancreatic duct was closed with Hem-O-lock. CUSA is an alternative to stapler dissection during LDP in select patients.

Gastric carcinoma is one of the most common and deadly malignancies nowadays, and carbohydrate antigen 19-9 (CA 19-9) in gastric juice has been rarely studied. To compare peri-distal gastrectomy (DG) gastric juice and serum CA 19-9 and reveal its significance, we selected 67 patients diagnosed with gastric carcinoma who underwent DG, and collected their perioperative gastric juice whose CA 19-9 was detected, with serum CA 19-9 monitored as a comparison. We found that: gastric juice CA 19-9 pre-gastrectomy was significantly correlated with tumor TNM classification, regarding tumor size, level of gastric wall invaded, differentiated grade and number of metastatic lymph nodes as influencing factors, while serum CA 19-9 revealed little information; gastric juice CA 19-9 was significantly correlated with radical degree, and regarded number of resected lymph nodes and classification of cutting edge as impact factors; thirteen patients whose gastric juice CA 19-9 rose post-DG showed features indicating poor prognosis; the difference of gastric juice CA 19-9 between pre- and post-gastrectomy was correlated with tumor TNM classification and radical degree, and regarded tumor size, number of resected metastatic and normal lymph nodes, sum of distances from tumor to cutting edges and classification of cutting edge as influential factors. We conclude that peri-DG gastric juice CA 19-9 reveals much information about tumor and radical gastrectomy, and may indicate prognosis; while serum CA 19-9 has limited significance. PMID:24482710

Laparoscopic proximal gastrectomy (LPG) has recently been applied for early gastric cancer (EGC) in the upper stomach as a minimally invasive and function-preserving surgery. This study aimed to clarify the feasibility and nutritional benefits of LPG over laparoscopic total gastrectomy (LTG). This was a retrospective study of 77 patients with clinical stage I gastric cancer in the upper stomach. Of these patients, 25 underwent LPG, while 52 underwent LTG. Surgical outcomes and postoperative nutritional status such as changes in body weight and blood chemistries were compared between LPG and LTG. Intraoperative blood loss and C-reactive protein levels at 3 and 7 days after surgery were significantly lower in LPG than in LTG (p = 0.018, 0.036, and 0.042, respectively). No significant differences were observed in postoperative early or late complication rates between LPG and LTG. The incidence of Los Angeles Grade B or more severe reflux esophagitis after LPG was 9.1 %, which was similar to that after LTG (9.3 %). Postoperative changes in body weight at 6 months and 1 and 2 years after surgery were consistently less in LPG than in LTG (p = 0.001, 0.022, and 0.001, respectively). Moreover, postoperative levels of hemoglobin and serum albumin and total lymphocyte count were also higher in LPG than in LTG. LPG may be a better choice for EGC in the upper stomach than LTG because it has distinct advantages in terms of surgical invasiveness and postoperative nutritional status.

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

Laparoscopic sleeve gastrectomy (LSG) has been increasingly adopted as a revisional surgery for failed gastric banding. However, little information is available regarding the outcome of revisional LSG for band erosion. A retrospective database analysis was performed to study LSG as revisional surgery for band erosion. For staged revision, we waited a minimum of 3 months after band removal, and for single-stage revision, the band was removed by gastrotomy, and sleeve gastrectomy was performed at the same time. Main outcome measures were success rates of therapeutic strategies, morbidity, and mortality rates, length of stay, and body mass index (BMI) (percentage excess weight loss [%EWL]) before and after revision. From March 2011 to February 2013, 9 female patients underwent revisional LSG. Average age was 34.7 years. Six patients underwent a staged procedure, and the other 3 underwent a single-stage revision. Among the 6 staged patients, eroded bands had been removed by laparoscopy in 4 and by endoscopy in 2 without complications. Their LSGs were performed at a median of 4.4 months after band removal. Another 2 patients underwent single-stage revision. In the last patient, band erosion was incidentally found during a revisional LSG for insufficient weight loss. No mortality occurred. There were one stenosis and two proximal leaks. Two patients with leak underwent total gastrectomy and fistulojejunostomy. After a mean follow-up of 19.1 months, all 9 patients exhibited weight loss. The mean (±standard deviation [SD]) pre- and post-LSG BMIs were 34.0±4.4 and 25.6±2.1 kg/m(2), respectively, and their mean (±SD) %EWL from prebanding was 86.8±10.1%. Revisional LSG resulted in a further median %EWL of 28.0% (range, 7.9%-68.9%) versus weight at time of band removal. Revisional LSG after band erosion was found to be feasible and effective. However, it is prone to severe complication. In selected cases of band erosion, LSG can be performed at the time of band removal

To compare the short-term safety and costs between laparoscopic assisted or totally laparoscopic uncut Roux-en-Y and Billroth II((BII() + Braun reconstruction after radical gastrectomy of distal gastric cancer. Clinical data from our prospective database of radical gastrectomy were systematically analyzed. The patients who underwent laparoscopic gastrectomy with uncut Roux-en-Y or BII(+ Braun reconstruction between March 1st, 2015 and June 30th, 2017 were screened out for further analysis. Both the reconstructions were completed by linear staplers. Uncut Roux-en-Y reconstruction was performed with a 45 mm no-knife linear stapler (ATS45NK) on the afferent loop below the gastrojejunostomy. Continuous variables were compared using independent samples t test or Mann-Whitney U. The frequencies of categorical variables were compared using Chi-squared or Fisher exact test. Eighty-one patients were in uncut Roux-en-Y group and 58 patients were in BII(+Braun group.

AIM: To assess the efficacy and safety of intracorporeal esophagojejunostomy in patients undergoing laparoscopic total gastrectomy (LTG) for gastric cancer. METHODS: A retrospective review of 81 consecutive patients who underwent LTG with the same surgical team between November 2007 and July 2014 was performed. Four types of intracorporeal esophagojejunostomy using staplers or hand-sewn suturing were performed after LTG. Data on clinicopatholgoical characteristics, occurrence of complications, postoperative recovery, anastomotic time, and operation time among the surgical groups were obtained through medical records. RESULTS: The average operation time was 288.7 min, the average anastomotic time was 54.3 min, and the average estimated blood loss was 82.7 mL. There were no cases of conversion to open surgery. The first flatus was observed around 3.7 d, while the liquid diet was started, on average, from 4.9 d. The average postoperative hospital stay was 10.1 d. Postoperative complications occurred in 14 patients, nearly 17.3%. However, there were no cases of postoperative death. CONCLUSION: LTG performed with intracorporeal esophagojejunostomy using laparoscopic staplers or hand-sewn suturing is feasible and safe. The surgical results were acceptable from the perspective of minimal invasiveness. PMID:27022225

Reconstruction of the digestive tract involving esophageal anastomosis after laparoscopic gastrectomy is a surgically difficult procedure. In this study, a newly developed transoral pretilted circular anvil, a "the oral to the abdomen" method, was proven to be effective. A total of 34 consecutive patients underwent esophageal anastomosis using the OrVil in our hospital from July 2009 to February 2011. The esophagus was transected and a small hole was then made in the esophageal stump through which the nasogastric tube of the OrVil was passed to insert the anvil into the abdominal cavity. After fixation with a stapler and a glove at the jejunal loop or the remnant stomach, the abdominal cavity was entered through the minilaparotomy. Pneumoperitoneum and airtightness were reestablished after the glove edge was turned over to seal off the protector. Eventually, intracorporeal esophagojejunostomy or esophagogastrostomy was accomplished under the guidance of laparoscopy. There were 34 patients in the study: 1 with Zollinger-Ellison syndrome, 7 with stromal tumors in cardia, 23 with adenocarcinoma in the stomach, and 3 with cardia adenocarcinoma involving the lower esophagus. The surgical margins for all tumor patients were negative for tumor cells. The mean operative time was 175.0 minutes (90 to 240 min) and the mean intraoperative blood loss was 195.6 mL (50 to 800 mL). The 34 patients underwent successful laparoscopic surgeries with no open conversions. For 32 patients, there were no technological complications in the transoral insertion of the anvil to the esophageal stump. There were no anastomotic leaks after the surgery. The use of the OrVil device, a "the oral to the abdomen" method, changes the direction of the anvil insertion and significantly decreases both difficulty and duration of the laparoscopic surgery. More importantly, if the mass is at a higher position, this approach can achieve a higher surgical margin compared with the hand-sewn purse

The minimally invasive surgery for gastric cancer in Brazil has begun about two years after the first laparoscopic gastrectomy (LG) performed by Kitano in Japan, in 1991. Although the report of first surgeries shows the year of 1993, there was no dissemination of the technique until the years 2010. At that time with the improvement of optical devices, laparoscopic instruments and with the publications coming from Asia, several Brazilian surgeons felt encouraged to go to Korea and Japan to learn the standardization of the LG. After that there was a significant increase in that type of surgery, especially after the IRCAD opened a branch in Brazil. The growing interest for the subject led some services to begin their own experience with the LG and, since the beginning, the results were similar with those found in the open surgery. Nevertheless, there were some differences with the papers published initially in Japan and Korea. In those countries, the surgeries were laparoscopic assisted, meaning that, in the majority of cases, the anastomoses were done through a mini-incision in the end of the procedure. In Brazil since the beginning it was performed completely through laparoscopic approach due to the skills acquired by Brazilian surgeons in bariatric surgeries. Another difference was the stage. While in the east the majority of cases were done in T1 patients, in Brazil, probably due to the lack of early cases, the surgeries were done also in advanced cases. The initial experience of Zilberstein et al. revealed low rates of morbidity without mortality. Comparing laparoscopic and open surgery, the group from Barretos/IRCAD showed shorter surgical time (216×255 minutes), earlier oral or enteral feeding and earlier hospital discharge, with a smaller number of harvested lymph nodes (28 in laparoscopic against 33 in open surgery). There was no significant difference regarding morbidity, mortality and reoperation rate. In the first efforts to publish a multicentric study

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

Strategic laparoscopic surgery for improved cosmesis (SLIC) is a less invasive surgical approach than conventional laparoscopic surgery. The aim of this study was to examine the feasibility and safety of SLIC for general and bariatric surgical operations. Additionally, we compared the outcomes of laparoscopic sleeve gastrectomy with those performed by the SLIC technique. In an academic medical center, from April 2008 to December 2010, 127 patients underwent SLIC procedures: 38 SLIC cholecystectomy, 56 SLIC gastric banding, 26 SLIC sleeve gastrectomy, 1 SLIC gastrojejunostomy, and 6 SLIC appendectomy. SLIC sleeve gastrectomy was initially performed through a single 4.0-cm supraumbilical incision with extraction of the gastric specimen through the same incision. The technique evolved to laparoscopic incisions that were all placed within the umbilicus and suprapubic region. There were no 30-day or in-hospital mortalities or 30-day re-admissions or re-operations. For SLIC cholecystectomy, gastric banding, appendectomy, and gastrojejunostomy, conversion to conventional laparoscopy occurred in 5.3%, 5.4%, 0%, and 0%, respectively; there were no major or minor postoperative complications. For SLIC sleeve gastrectomy, there were no significant differences in mean operative time and length of hospital stay compared with laparoscopic sleeve gastrectomy; 1 (3.8%) of 26 SLIC patients required conversion to five-port laparoscopy. There were no major complications. Minor complications occurred in 7.7% in the SLIC sleeve group versus 8.3% in the laparoscopic sleeve group. SLIC in general and bariatric operations is technically feasible, safe, and associated with a low rate of conversion to conventional laparoscopy. Compared with laparoscopic sleeve gastrectomy, SLIC sleeve gastrectomy can be performed without a prolonged operative time with comparable perioperative outcomes.

The present study was conducted to investigate the prognosis and survival of patients with locally advanced gastric cancer who underwent distal subtotal gastrectomy with modified D2 (D1+) and D2 lymphadenectomy, under 70 years of age. The five-year overall survival rates of 390 patients were compared between those receiving D1+ and D2 lymphadenectomy. Univariate and multivariate analyses were used to identify factors that correlated with prognosis and lymph node metastasis. Tumor size (P=0.039), pT stage (P=0.011), pN stage (P<0.001), and lymphadenectomy (P=0.004) were identified as independent prognostic factors. Furthermore, tumor size (P=0.022), pT stage (P=0.012), and lymphadenectomy (P=0.028) were proven as independent factors predicting lymph node metastasis. In conclusion, cancers of larger size, higher pT stage, and with D1+ lymphadenectomy had a higher risk of lymph node metastasis. Standard D2 lymphadenectomy removes sufficient lymph nodes to improve staging accuracy and survival. Therefore, D2 lymphanectomy is recommended in distal subtotal gastrectomy for locally advanced gastric cancer, especially for cancers of larger size and higher pT stage.

The aim of this study was to investigate the feasibility of sentinel node mapping using a fluorescent dye and visible light in patients with gastric cancer. Recently, fluorescent imaging technology offers improved visibility with the possibility of better sensitivity or accuracy in sentinel node mapping. Twenty patients with early gastric cancer, for whom laparoscopic distal gastrectomy with standard lymphadenectomy had been planned, were enrolled in this study. Before lymphadenectomy, the patients received a gastrofiberoscopic peritumoral injection of fluorescein solution. The sentinel basin was investigated via laparoscopic fluorescent imaging under blue light (wavelength of 440-490 nm) emitted from an LED curing light. The detection rate and lymph node status were analyzed in the enrolled patients. In addition, short-term clinical outcomes were also investigated. No hypersensitivity to the dye was identified in any enrolled patients. Sentinel nodes were detected in 19 of 20 enrolled patients (95.0%), and metastatic lymph nodes were found in 2 patients. The latter lymph nodes belonged to the sentinel basin of each patient. Meanwhile, 1 patient (5.0%) experienced a postoperative complication that was unrelated to sentinel node mapping. No mortality was recorded among enrolled cases. Sentinel node mapping with visible light fluorescence was a feasible method for visualizing sentinel nodes in patients with early gastric cancer. In addition, this method is advantageous in terms of visualizing the concrete relationship between the sentinel nodes and surrounding structures.

To compare the safety and effectiveness of circular stapler and linear stapler in Billroth II( anastomosis following distal gastrectomy for gastric cancer patients. Clinical data of gastric adenocarcinoma patients who received distal gastrectomy with Billroth II( anastomosis at Ward IIII( of Gastrointestinal Cancer Center of Peking University Cancer Hospital from January 2013 to April 2017 were collected retrospectively. (1) patients identified as stage IIII( gastric cancer by preoperative clinical and postoperative pathological staging. (2) patients undergoing emergency operation due to perforation, obstruction, or bleeding of digestive tract. (3) patients receiving chemotherapy before operation. (4) patients undergoing combined organ resection due to tumor involving other organs. (5) patients complicating with other malignancies. A total of 116 cases were enrolled and divided into circular stapler (CS, 61 cases) group and linear stapler (LS, 55 cases) group according to the application of mechanical stapler. Clinicopathological characteristics, operative conditions and postoperative recovery were compared between two groups. Differences in baseline data, such as tumor size, Lauren classification, differentiation grade, and pathologic stage, between two groups were not statistically significant (all P>0.05). The mean operative time (230 min vs. 234 min), median intra-operative blood loss (50.0 ml vs. 50.0 ml), median number of harvested lymph node (28.0 vs. 26.0) and median number of positive lymph node (1.0 vs. 2.0) between LS group and CS group were not significantly different (all P>0.05) As compared to CS group, LS group presented shorter median time to the first flatus (3.0 days vs. 4.0 days, P=0.038), shorter median time to the first liquid diet (7.0 days vs. 8.0 days, P=0.000), shorter median time to remove the first abdominal drainage tube (7.0 days vs. 9.0 days, P=0.000) and shorter median time of postoperative hospital stay (8.0 days vs. 10.0 days, P=0

Objective: To evaluate the application value of carbon lymph node tracing technique by preoperative endoscopic subserosal injection in laparoscopic radical gastrectomy. Methods: From June 2013 to February 2015, seventy eight patients with gastric cancer were enrolled and randomly divided into trial group and control group. Subserosal injection of carbon nanoparticles around the tumor was performed by preoperative endoscopic subserosal injection one day before the operation in trial group, while the patients routinely underwent laparoscopic gastrectomy in control group. Results of harvested lymph nodes, postoperative complications were compared between the two groups. Carbon nanoparticle-related side effect was also evaluated. Results: The average number of harvested lymph node in trial group was significantly higher than that in control group (35.5±8.5 vs 29.5±6.5, P <0.05). The rate of overall black-dyed harvested lymph node was 74.7% (1 035/1 386) in trial group, the black-dyed lymph node rate in D1 lymph node was 80.1%, which was significantly higher than that in D2 lymph node (69.8%, χ 2 =19.38, P <0.01). When comparing the lymph node with and without black-dyed in trial group, the rate of metastasis lymph node was significantly higher in lymph node with black-dyed (17.3% vs 4.0%, χ 2 =38.67, P <0.01). There was no significant difference in postoperative complications rate between two group (trial group 10.2%; control group 12.8%, χ 2 =0.00, P >0.05), and no carbon nanoparticle-related side effect was observed. Conclusion: Given a higher harvested lymph node number and a similar rate of complications, preoperative endoscopic subserosal injection of carbon nanoparticles was safe and feasible.

Improvement of dyslipidemia is an important benefit of bariatric surgery. The benefits of laparoscopic sleeve gastrectomy (LSG) among dyslipidemia are still a matter of debate. We conducted a retrospective descriptive study between 2010 and 2013. Obese patients undergoing LSG, with recorded dyslipidemia at admission and a follow-up for at least 1 year, were included for analysis. Demographic characteristics, medication in use, and a complete lipid profile were collected before surgery. After surgery, weight was controlled at 1, 3, 6, and 12 months. Lipid profile was re-evaluated 1 year after surgery. Patients were divided according to weight loss into two groups: (A) adequate weight loss and (B) inadequate weight loss. Lipid profile evolution was then compared between groups. One hundred seven patients met the inclusion criteria. Pre-op mean BMI was 45.13 ± 7.5 kg/m 2 . One year after LSG, mean BMI was 30.6 ± 7.1 kg/m 2 with a change in BMI of 11.5 ± 6.6 kg/m 2 , a %TWL of 26.9 ± 13.5%, and a %EWL of 60.3 ± 36.6%. Hypercholesterolemia and hypertriglyceridemia remission was achieved in 45 and 86% of the patients and improved in another 19 and 4% respectively. Seventy-four percent improved HDL levels. LDL levels improved in 39% and remitted in 37%. Medication was discontinued in 43.7%. HDL increase and LDL, TG, and non-HDL-C decrease were significantly greater in group A. LSG produces an improvement in lipid profile, with a significant increase in HDL and a decrease in LDL, triglycerides, and non-HDL-C.

Laparoscopic sleeve gastrectomy (LSG) has become one of the most commonly performed bariatric procedures, largely due to several advantages it carries over more complex bariatric procedures. LSG is generally considered a straightforward procedure, but one of the major concerns is a staple line leak. The objectives of this study are to evaluate the correlation between surgeon's experience and leak rate and to assess the different risk factors for developing a gastric leak after LSG. Private hospital, France. The analysis of a single surgeon's yearly leak rate since the introduction of LSG for possible risk factors was done. A total of 2012 LSGs were performed in between September, 2005 and December, 2014. Twenty cases (1 %) of gastric leak were recorded. Of these, 17 patients were women (94.4 %) with a mean age of 39.4 years (range 22-61) and mean body mass index (BMI) 41.2 kg/m(2) (range 34.8-57.1). On a yearly basis, the leak rate was 4.8 % (2006), 5.7 % (2007), 0 (2008), 2.6 % (2009), 2 % (2010), 0.8 % (2011), 0.6 % (2012), 0.2 % (2013), and 0 (2014). In the first 1000 cases (group A), there were 18 cases of gastric leak and in the last 1000 cases, there were 800 with GORE® SEAMGUARD® Bioabsorbable Staple Line Reinforcement (group B) 2 cases of gastric leak (p = 0.009). A revisional LSG, 395 patients after gastric banding and 61 patients re-sleeve gastrectomy, was performed in 456 cases (22.7 %). There were 3 cases of leak (0.65 %). There were two deaths. LSG can be performed with a low complication rate. This large series of a single surgeon's experience demonstrated that the leak rate after LSG could be significantly decreased over time with changes in techniques.

Laparoscopy-assisted distal gastrectomy (LADG) for gastric cancer may prevent the development of an impaired nutritional status due to reduced surgical stress compared with open distal gastrectomy (ODG). This study was performed as an exploratory analysis of a phase III trial comparing LADG and ODG for stage I gastric cancer during the period between May and December of 2011. All patients received the same perioperative care via fast-track surgery. The level of surgical stress was evaluated based on the white blood cell count and the interleukin-6 (IL-6) level. The nutritional status was measured according to the total body weight, amount of lean body mass, lymphocyte count, and prealbumin level. Twenty-six patients were randomized to receive ODG (13 patients) or LADG (13 patients). The baseline characteristics and surgical outcomes were similar between the two groups. The median IL-6 level increased from 0.8 to 36.3 pg/dl in the ODG group and from 1.5 to 53.3 pg/dl in the LADG group. The median amount of lean body mass decreased from 48.3 to 46.8 kg in the ODG group and from 46.6 to 46.0 kg in the LADG group. There are no significant differences between two groups. The level of surgical stress and the nutritional status were found to be similar between the ODG and LADG groups in a randomized comparison using the same perioperative care of fast-track surgery.

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

We report an option for delta-shaped gastroduodenostomy in totally laparoscopic distal gastrectomy (TLDG) for gastric cancer. We detail a single-layer suturing technique for the endoscopic linear stapler entry hole using knotless barbed sutures combined with the application of additional knotted sutures. From June 2013 to February 2017, we performed TLDG with delta-shaped gastroduodenostomy in 20 patients with gastric cancer. The linear stapler was closed and fired to attach the posterior walls of the remnant stomach and the duodenum together. After creating a good view of the greater curvature side of the entry hole for the stapler by retracting the knotted suture on the lesser curvature side toward the ventral side, we performed single-layer entire-thickness continuous suturing of this hole using a 15-cm-long barbed suture running from the greater curvature side to the lesser curvature side. We placed the second and third stitches between the seromuscular layer of the remnant stomach and the entire-thickness layer of the duodenum while suturing the duodenal mucosa as minutely as possible. In addition, we routinely added one or two entire-thickness knotted sutures at the site near the greater curvature side. We placed similar additional knotted sutures at the site with a broad pitch. TLDG with this reconstruction technique was successfully performed in all patients with no occurrences of anastomotic leakage or intraabdominal abscess around the anastomosis. It is suggested that this method can be one option for delta-shaped gastroduodenostomy in TLDG due to its cost-effectiveness and feasibility.

AIM: To evaluate the effectiveness of endoscopic submucosal dissection using an insulation-tipped diathermic knife (IT-ESD) for the treatment of patients with gastric remnant cancer. METHODS: Thirty-two patients with early gastric cancer in the remnant stomach, who underwent distal gastrectomy due to gastric carcinoma, were treated with endoscopic mucosal resection (EMR) or ESD at Sumitomo Besshi Hospital and Shikoku Cancer Center in the 10-year period from January 1998 to December 2007, including 17 patients treated with IT-ESD. Retrospectively, patient backgrounds, the one-piece resection rate, complete resection (CR) rate, operation time, bleeding rate, and perforation rate were compared between patients treated with conventional EMR and those treated with IT-ESD. RESULTS: The CR rate (40% in the EMR group vs 82% in the IT-ESD group) was significantly higher in the IT-ESD group than in the EMR group; however, the operation time was significantly longer for the IT-ESD group (57.6 ± 31.9 min vs 21.1 ± 12.2 min). No significant differences were found in the rate of underlying cardiopulmonary disease (IT-ESD group, 12% vs EMR group, 13%), one-piece resection rate (100% vs 73%), bleeding rate (18% vs 6.7%), and perforation rate (0% vs 0%) between the two groups. CONCLUSION: IT-ESD appears to be an effective treatment for gastric remnant cancer post distal gastrectomy because of its high CR rate. It is useful for histological confirmation of successful treatment. The long-term outcome needs to be evaluated in the future. PMID:18442204

Laparoscopic sleeve gastrectomy with duodenojejunal bypass (LSG-DJB), which has been positioned as a novel bariatric procedure, is the combination of vertical sleeve gastrectomy and proximal intestinal bypass and is theoretically expected to have strong anti-diabetic effect. Also, preserving the pylorus, a physiological valve, leads to less occurrence of dumping syndrome and anastomotic stenosis which are often problematic after laparoscopic Roux-en-Y gastric bypass (LRYGB), a gold standard. The purpose of this study was to investigate the clinical effects of LSG-DJB on obese patients with type 2 diabetes mellitus (T2DM). Consecutive 75 obese patients (female 44/male 31) associated with T2DM who underwent LSG-DJB and were followed up for at least 1 year were analyzed. The mean age was 45.5 ± 8.6 years, and the mean preoperative body weight (BW) and body mass index (BMI) were 108.4 ± 21.4 kg and 39.6 ± 7.3 kg/m(2), respectively. The mean hemoglobin A1c (HbA1c) at the first visit was 9.0 ± 1.9 %, and the duration of T2DM from diagnosis was 7.2 ± 6.2 years. Thirty-six out of the 75 patients (48 %) were treated with insulin preoperatively. All patients were evaluated and managed under a strict multidisciplinary team approach. The follow-up rate at 1 year was 89 %. At 1 year, the mean BW and BMI significantly dropped to 74.6 ± 16.9 kg and 27.5 ± 5.7 kg/m(2), respectively. The mean percent of excess weight loss (%EWL) and percent of total body weight loss (%TWL) were 99.4 ± 42.4 and 31.6 ± 8.8 %, respectively. Consequently, 68.7 % of the patients achieved HbA1c less than 6 %, and 82.1 % of them achieved HbA1c less than 6.5 % without diabetes medications. Glycemic control of HbA1c less than 7 % was achieved in 91.0 % of the patients. The percentage of patients who satisfied the American Diabetes Association (ADA)-defined composite endpoints for cardiovascular disease (CVD) risk factor control increased from 0

Pancreatic neuroendocrine tumors (PNETs) account for 1-2% of all pancreatic neoplasms. Nonfunctioning PNETs (NF-PNETs) account for 60-90% of all PNETs. Laparoscopic distal pancreatectomy (LDP) is becoming the treatment of choice for benign lesions in the body and tail of the pancreas. However, LDP has not yet been widely accepted as the gold standard for NF-PNETs. The purpose of this study is to evaluate the clinical and oncologic outcomes after laparoscopic versus open distal pancreatectomy (ODP) for NF-PNETs. Between April 1995 and September 2016, 94 patients with NF-PNETs underwent open or laparoscopic distal pancreatectomy at Samsung Medical Center. Patients were divided into two groups: those who underwent LDP and those who underwent ODP. Both groups were compared in terms of clinical and oncologic variables. LDP patients had a significantly shorter hospital stay compared with ODP patients, amounting to a mean difference of 2 days (p < 0.001). Overall complication rates did not differ significantly between the ODP and LDP groups (p = 0.379). The 3-year overall survival rates in the ODP and LDP groups were 93.7 and 100%, respectively (p = 0.069). In this study, LDP for NF-PNETs had similar oncologic outcomes compared with ODP. In addition, LDP was associated with a shorter hospital stay compared with ODP. Therefore, LDP is a safe and effective procedure for patients with NF-PNETs. A multicenter study and a randomized controlled trial are needed to better assess the clinical and oncologic outcomes.

To explore the analgesic effects and postoperative recovery of ropivacaine incision infiltration in elderly patients after total laparoscopic radical gastrectomy. The clinical data were obtained prospectively from 61 elderly patients ( ≥ 65y) undergoing traditional total laparoscopic radical gastrectomy under standard general anesthesia at our department during January 2012 and September 2013. After surgery, they were randomly double-blindly divided into 3 groups: local infiltration of ropivacaine group (0.5% ropivacaine incision infiltration, 40 ml, n = 22), local infiltration of sodium chloride group (0.9% sodium chloride injection incision infiltration, 40 ml, n = 20) and control group (no analgesic, n = 19). The intensity of postoperative pain was evaluated by numeric rating scale (NRS). And 10 mg of morphine was administered intramuscularly as rescue medication when NRS exceeded 4.NRS, cases on remedy analgesia and associated side effects were observed and recorded after 6 h postoperatively. A comparative study was made for postoperative first ambulation time, intestinal function recovery time, complication incidence, postoperative hospital stay and medical expenses among three groups. Significant postoperative difference existed in NRS at 6, 12, 24, 48 h among ropivacaine, sodium and control groups respectively (6 h: 2.65 ± 0.25 vs 5.47 ± 0.12 vs 5.63 ± 0.27, 12 h: 2.42 ± 0.34 vs 5.82 ± 0.63 vs 5.67 ± 0.49, 24 h: 2.27 ± 0.83 vs 3.95 ± 0.51 vs 3.84 ± 0.60, 48 h: 2.05 ± 0.90 vs 3.75 ± 0.72 vs 3.74 ± 0.56, P < 0.05) . The patients with ropivacaine local infiltration had a lower rate of remedy analgesia than those with sodium chloride injection incision infiltration or without analgesic (both P < 0.05). There was no obvious adverse effect of ropivacaine infiltration at 48 h postoperatively. Both postoperative first ambulation and peristalsis recovery time were shorter (P < 0.05) in ropivacaine group ((53 ± 9) and (80 ± 6) h) than sodium group ((91

The current standard of care is to perform a postoperative gastrografin study following laparoscopic sleeve gastrectomy (LSG) to detect leakage or obstruction. This study evaluated the usefulness of this routine procedure. A retrospective chart review was performed in December 2012. All patients had routine intraoperative methylene blue testing to check for possible leakage from the staple line, and any leaking points were oversewn. We also performed postoperative contrast study (gastrografin) routinely in the first 24-48 h for all patients. From June 2007 to December 2012, 712 cases underwent LSG during the study period. Patients included in this study were 556 women (78.1%) and 156 men (21.9%). The mean age was 35 years. The mean BMI was 48 kg/m2. The operative time was 107 ± 29 min, and there were no conversions to open surgery. Intraoperative methylene blue test detected leakage in 28 cases (3.93%). Postoperative contrast study (gastrografin) was negative for leakage in all cases. Computed tomography (CT) scan with oral contrast study detected leakage in 1.4% (ten cases); none of these cases were detected by regular contrast study. Our study showed that intraoperative methylene blue test for leakage is a very sensitive and effective method for detecting leakage during sleeve gastrectomy and should be done routinely in all cases. Routine postoperative contrast study is not needed to detect leakage unless clinically indicated in selected cases, and in such cases contrast-enhanced CT scans are the modality of choice.

The aim of this study was to evaluate the clinical advantages of Roux-en-Y (R-Y) and Billroth-I (B-I) reconstruction after distal gastrectomy for gastric cancer by examining the postoperative symptoms based on a patient questionnaire and patient nutrition. In addition, this study determined which of the R-Y or B-I procedures is preferable following distal gastrectomy. Fifty-one patients who had undergone R-Y reconstruction and 50 patients who had undergone B-I reconstruction were retrospectively enrolled in this study. The operative and postoperative findings such as operating time, blood loss, complications, and postoperative hospital stay were evaluated as short-term clinical outcomes. Postoperative serum nutrition parameters, transition of body weight, incidence of residual gastritis, and clinical symptoms were evaluated as mid-term clinical outcomes. An assessment of symptoms was based on a questionnaire concerning dumping symptoms, reflux symptoms, food intake, and satisfaction with the operation. No significant differences were observed in the operative and postoperative clinical parameters without stage grouping. The transition of serum nutrition parameters revealed no significant differences between the two groups for the preoperative and postoperative states. Dumping symptoms, reflux symptoms, and abdominal symptoms were less frequent in R-Y patients, but there were no significant differences between the two groups. Moreover, the differences in body weight recovery rates were not found to be statistically significant between two groups. However, the incidence of residual gastritis was significantly less in R-Y patients (21.2%) than in B-I patients (68.8%) (p < 0.05). The questionnaire results regarding food intake and surgery satisfaction were not significantly different between the two groups. Definite clinical advantages were not recognized in patients with R-Y reconstruction. B-I and R-Y reconstructive procedures should be selected according to the

Laparoscopic spleen-preserving distal pancreatectomy (LSPDP) is expected to be less invasive than laparoscopic distal pancreatectomy with splenectomy. However, there are few reports regarding the details of the procedure for LSPDP, and its safety remains unclear. This study aimed to evaluate the feasibility and safety of LSPDP. Six patients underwent LSPDP from March 2009 to February 2013 in our center, and their clinical data and outcomes were reviewed retrospectively. A total of six laparoscopic distal pancreatic resections were attempted in four female and two male patients. All of the operations were successful, with an average operative time of 290.7 min (range: 211-377 min) and an average blood loss of 43.5 g (range: 0-142 g). The mean hospital stay was 11.8 days (range: 9-17days). No obvious pancreatic fistulas occurred, although pseudocysts at the stump of the pancreas were recognized in three patients on CT scans performed at 7 days postoperatively. Postoperative pathological examinations revealed two cases of serous cystadenoma in the body and tail of the pancreas, one case of serous oligocystic adenoma, one case of mucinous cystadenoma, one case of neuroendocrine tumor, and one case of solid-pseudopapillary neoplasm. LSPDP is minimally invasive, safe, and feasible for the management of benign pancreatic tail tumors, with the advantages of earlier recovery and less morbidity from complications.

Laparoscopic sleeve gastrectomy (LSG) has gained popularity as a treatment of choice for morbid obesity and associated comorbidities. There has been a concern about new onset or worsening of gastroesophageal reflux (GERD) following LSG. The objective of the study was to evaluate the effect of surgically treating hiatal weakness on GERD symptoms in patients undergoing LSG. Single tertiary referral institution, Sydney, Australia. A prospective observational cohort study was conducted with consecutive patients undergoing LSG. Hiatal findings, patient demographics, medications and reflux score were recorded prospectively. Patients were followed up post-operatively for a minimum of 12 months and assessed using GERD-HRQL score to quantify reflux symptoms. Data from 100 patients with a minimum of 1-year follow-up were analysed. Mean follow-up was 18.9 months. Overall, GERD-HRQL improved from mean 4.5 ± 5.8 pre-operatively to 0.76 ± 1.5 after 18.9 months (p = 0.0001). For those with pre-operative reflux, GERD-HRQL improved from mean (SD) 8.43 ± 6.26 pre-operatively to 0.94 ± 1.55 (p = 0.0001). All the nine patients with troublesome daily reflux significantly improved. For those without pre-operative reflux, GERD-HRQL improved from 0.88 ± 1.37 to 0.47 ± 1.25 (p-ns) post-operatively. On multivariate analysis, higher pre-operative reflux and dysphagia/bloat scores, younger age and lower percentage excess weight loss after 18.9 months were associated with GERD-HRQL improvement. In the medium term, GERD-HRQL improves following sleeve gastrectomy with meticulous hiatal assessment and repair of hiatal laxity and herniation.

This systematic review and meta-analysis was performed to compare the influence of different calibrating bougie sizes on clinical outcomes in laparoscopic sleeve gastrectomy (LSG) for patients with obesity. A systematic review of the literature was performed using the key words: "laparoscopic sleeve gastrectomy", "bougie size", "calibration", "obesity", and "obese" for searches of electronic databases up to October 2017. Clinical characteristics such as, the percentage of excess weight loss (%EWL), overall complications, gastrointestinal leaks, gastroesophageal reflux disease (GERD) were pooled by meta-analysis. Stata 12.0 (Stata Corp, College Station, TX, USA) was used to perform the meta-analysis. Data were extracted from 11 original studies matching our inclusion criteria. In our review, the group of patients who had operations with thinner bougies had a greater %EWL (SMD 0.23, 95% CI 0.14-0.33, P < .001) than the group where larger diameters were used. Furthermore, no significant differences were found in the incidence of overall complications (OR 1.00, 95% CI 0.73-1.37, P = .978), postoperative gastrointestinal leaks (OR 0.91, 95% CI 0.67-1.24, P = .554), and GERD (OR 0.77, 95% CI 0.37-1.59, P = .476) between the two groups. A robust result could not be made about remission of comorbidities using differing diameter bougies due to insufficient data. Use of thinner diameter bougies in LSG was more effective in enabling weight loss and did not increase the risk of overall complications, gastrointestinal leaks or GERD compared with larger diameter bougies.

Two main causes for nutrient deficiencies following bariatric surgery (BS) are pre-operative deficiencies and favoring foods with high-energy density and poor micronutrient content. The aims of this study were to evaluate nutritional status and gender differences and the prevalence of nutritional deficiencies among candidates for laparoscopic sleeve gastrectomy (LSG) surgery. A cross-sectional analysis of pre-surgery data collected as part of a randomized clinical trial on 100 morbidly obese patients with non-alcoholic fatty liver disease (NAFLD) admitted to LSG surgery at Assuta Medical Center between February 2014 and January 2015. Anthropometrics, food intake, and fasting blood tests were evaluated during the baseline visit. One-hundred patients completed the pre-operative measurements (60 % female) with a mean age of 41.9 ± 9.8 years and a mean BMI of 42.3 ± 4.7 kg/m(2). Pre-operatively, deficiencies for iron, ferritin, folic acid, vitamin B1, vitamin B12, vitamin D, and hemoglobin were 6, 1, 1, 6, 0, 22, and 6 %, respectively. Pre-surgery, mean energy, protein, fat, and carbohydrate intake were 2710.7 ± 1275.7 kcal/day, 114.2 ± 48.5, 110.6 ± 54.5, and 321.6 ± 176.1 gr/day, respectively. The intakes for iron, calcium, folic acid, vitamin B12, and vitamin B1 were below the Dietary Reference Intake (DRI) recommendations for 46, 48, 58, 14, and 34 % of the study population, respectively. We found a low prevalence of nutritional deficiencies pre-operatively except for vitamin D. Most micronutrient intake did not reach the DRI recommendations, despite high-caloric and macronutrient intake indicating a poor dietary quality.

The impact of laparoscopic sleeve gastrectomy (LSG) on various co-morbidities including type II diabetes mellitus, hypertension, and sleep apnea is well established. However, its effect on hypothyroidism has not been given due attention evidenced by the scant literature on the subject. The purpose of this report is to assess the change in thyroxine (T4) requirement in morbidly obese patients with clinical hypothyroidism after LSG. We conducted a retrospective review of morbidly obese patients on T4 replacement therapy for clinical hypothyroidism who underwent LSG from August 2009 to July 2012 at our institution. Of the 200 patients who underwent LSG during this period, 21 (10.5 %) were on T4 replacement therapy preoperatively for clinical hypothyroidism. Two patients were lost to follow-up. The remaining 19 patients were categorized into two groups. Group 1 comprised 13 patients with decreased T4 requirements after LSG. Group 2 comprised six patients in whom the T4 dose remained unaltered. The mean change in T4 requirement in group 1 was 42.07 % (12-100 %). Group 1 patients had a significantly higher mean preoperative body mass index (48.7 vs. 43.0 kg/m(2); p = 0.03) than the group 2 patients. There was a significant correlation between the percentage excess weight loss and the percentage change in T4 requirement in group 1 (r = 0.607, p = 0.028). Sleeve gastrectomy has a favorable impact on hypothyroid status as seen by a reduction in T4 requirement in the majority of morbidly obese patients with overt hypothyroidism.

This randomized, controlled trial evaluated the clinical efficacy of Billroth I (BI) and Roux-en-Y (RY) reconstruction at 1 year after distal gastrectomy for gastric cancer. The primary end point was the amount of body weight lost at 1 postoperative year, and secondary end points included other items related to nutritional status such as serum albumin and lymphocyte count, as well as endoscopic examination findings of the remnant stomach and esophagus. Of the 332 patients enrolled, 163 were assigned to the BI group and 169 were randomized to the RY group. The loss in body weight 1 year after surgery did not differ significantly between the BI and RY groups (9.1 % and 9.7 %, respectively, p = 0.39). There were no significant differences in other aspects of nutritional status between the 2 groups. Endoscopic examination 1 year after gastrectomy showed reflux esophagitis in 26 patients (17 %) in the BI group versus 10 patients (6 %) in the RY group (p = 0.0037), while remnant gastritis was observed in 71 patients (46 %) in the BI group versus 44 patients (28 %) in the RY group (p = 0.0013); differences were significant for both conditions. Multivariable analysis showed that the only reconstruction was the independently associated factor with the incidence of reflux esophagitis. RY reconstruction was not superior to BI in terms of body weight change or other aspects of nutritional status at 1 year after surgery, although RY more effectively prevented reflux esophagitis and remnant gastritis after distal gastrectomy.

The mechanisms involved in the weight loss seen after vertical sleeve gastrectomy (VSG) are not clear. The rat stomach has two morphologically and functionally distinct proximal and distal parts. The rat model for VSG involves complete removal of the proximal part and 80% removal of the distal part along the greater curvature. The purpose of this study was to understand the potential independent contributions of removal of these distinct gastric sections to VSG outcomes. We prepared four surgical groups of male Long-Evans rats: VSG, sham surgery (control), selective proximal section removal (PR), and selective distal section removal (DR). Gastric emptying rate (GER) was highest after VSG compared with all other groups. However, PR, in turn, had significantly greater GER compared with both DR and sham groups. The surgery-induced weight loss followed the same pattern with VSG causing the greatest weight loss and PR having greater weight loss compared with DR and sham groups. The results were robust for rats fed regular chow or a high-fat diet. Body mass analysis revealed that the weight loss was due to the loss of fat mass, and there was no change in lean mass after the surgeries. In conclusion, removal of the proximal stomach contributes to most, but not all, of the physiological impact of VSG. PMID:27581811

Altered gastric anatomy following laparoscopic sleeve gastrectomy (LSG) is likely to induce upper gastrointestinal (GI) symptoms. Published studies, however, have focused mainly on gastroesophageal reflux disease (GERD). This study aims to evaluate LSG's impact on the prevalence of upper GI symptoms and to assess the effects of time from surgery, weight loss, and proton pump inhibitor (PPI) therapy. The validated Rome III Criteria symptom questionnaire for upper GI symptoms, including quality of life items, has been self-administered to 97 patients who underwent LSG. Symptoms were analyzed either separately or altogether to classify patients in GERD or dyspepsia, subdivided in epigastric pain (EPS) and post-prandial distress (PDS) syndromes. Before LSG, 52.7% of the patients were asymptomatic, 27.0% had GERD, and 8.1% had dyspepsia (2.7% EPS, 5.4% PDS). After a median follow-up of 13 months, 91.9% of the patients complained of upper GI symptoms, the most prevalent being PDS (59.4 %). GERD prevalence did not differ before and after LSG. The only symptom strongly related to LSG was dysphagia (OR 4.7, 95% CI 1.3-20.4, p = 0.015), which was present in 19.7% of the patients and mainly associated with PDS rather than GERD. GI symptoms, however, did not have a great impact on quality of life. Time from surgery, weight loss after surgery, as well as concomitant PPI, did not influence the symptoms. After a median follow-up of 13 months, PDS-like dyspepsia, rather than GERD, was the main complaint, both poorly responding to PPI therapy. A longer follow-up will be necessary to evaluate their future persistency.

Laparoscopic sleeve gastrectomy (LSG) has become popular due to its technical ease and excellent short-term results. Understanding the risk profile of LSG compared with the gold standard laparoscopic Roux-en-Y gastric bypass (LRYGB) is critical for patient selection. To use traditional regression techniques and random forest classification algorithms to compare LSG with LRYGB using the 2015 Metabolic and Bariatric Surgery Accreditation and Quality Improvement Data Registry. United States. Outcomes were leak, morbidity, and mortality within 30 days. Variable importance was assessed using random forest algorithms. Multivariate models were created in a training set and evaluated on the testing set with receiver operating characteristic curves. The adjusted odds of each outcome were compared. Of 134,142 patients, 93,062 (69%) underwent LSG and 41,080 (31%) underwent LRYGB. One hundred seventy-eight deaths occurred in 96 (.1%) of LSG patients compared with 82 (.2%) of LRYGB patients (P<.001). Morbidity occurred in 8% (5.8% in LSG versus 11.7% in LRYGB, P<.001). Leaks occurred in 1% (.8% in LSG versus 1.6% in LRYGB, P<.001). The most important predictors of all outcomes were body mass index, albumin, and age. In the adjusted multivariate models, LRYGB had higher odds of all complications (leak: odds ratio 2.10, P<.001; morbidity: odds ratio 2.02, P<.001; death: odds ratio 1.64, P<.01). In the Metabolic and Bariatric Surgery Accreditation and Quality Improvements data registry for 2015, LSG had half the risk-adjusted odds of death, serious morbidity, and leak in the first 30 days compared with LRYGB.

The mechanisms underlying peritoneal metastasis (PM) after curative gastrectomy for gastric cancer (GC) are not well elucidated. This study assessed whether viable cancer cells, including cancer stemlike cells (CSCs), were present in the remnant stomach immediately before gastrointestinal (GI) tract reconstruction because these could be a source of PM after gastrectomy. Saline fluid used for remnant stomach lumen irrigation before GI reconstruction was prospectively collected from 142 consecutive patients undergoing distal gastrectomy for GC and cytologically examined. Proliferative activity (Ki67 staining) and stemness (expression of the CSC surface markers CD44s or CD44v6) were evaluated in detected cancer cells. Viable cancer cells were detected in 33 (23.2 %) of the 142 remnant stomachs. These cells formed clusters and stained positively for Ki67, indicating proliferation. Cancer cells in remnant stomachs and surface cancer cells in primary GCs from 10 (30.3 %) of these 33 cases also stained positively for CD44s or CD44v6. In a multiple logistic regression analysis, advanced cancer (odds ratio [OR], 4.65; 95 % confidence interval [CI], 1.32-16.4; P = 0.017), tumor size of 40 mm or larger (OR, 3.78; 95 % CI, 1.12-12.8; P = 0.033), and histologic differentiation (OR, 3.10; 95 % CI, 1.30-7.40; P = 0.011) were associated independently with the presence of cancer cells in the remnant stomach. Viable, proliferative, and clustered cancer cells, including CSCs, were found in remnant gastric lumens immediately before GI reconstruction, indicating a possible cellular source of PM after curative gastrectomy for GC. Dissemination of gastric contents into the peritoneal cavity should be avoided during GI reconstruction.

To evaluate the self-esteem and quality of life in adolescents with extreme obesity before and one year after laparoscopic sleeve gastrectomy as obesity is a major challenging medical problem, not only in adults but also in children and adolescents in Saudi Arabia. In a prospective cohort study, 32 adolescents (aged 13-17 years) with extreme obesity (Group 1) presenting for laparoscopic sleeve gastrectomy (LSG) were compared with 32 matched, healthy, nonobese adolescents (aged 14-17 years) (Group 2) with regards to self-esteem and quality of life. Assessment was done using the Rosenberg Self-Esteem Scale and Pediatric Quality of Life Inventory version 4.0 (self- and parent report), respectively. Body mass index (BMI) Z scores were calculated for both groups. We found significantly poor self-esteem and impairment in all domains of quality of life (self- and parent report) in Group 1 compared with Group 2 (P<.001). Self esteem and quality of life (self- and parent reports) significantly improved 1 year after LSG (P<.001), and the weight loss induced by LSG, reflected by a decrease in BMI Z scores, was a significant predictor for the improvement in self-esteem (R2=0.28 and P=.003) and quality of life (R(2)=0.67 and P<.001). LSG was found to be a safe and effective operation in adolescents with extreme obesity: LSG leads to weight loss, with subsequent improvement in self-esteem and quality of life.

A serious complication of laparoscopic sleeve gastrectomy (LSG) is bleeding that is primarily located along the staples lines. Bleeding may be due to several causes, including hematomas, trocar sites, or visceral pseudo-aneurysms. We reported here a case of bleeding related to a pseudo-aneurysm of the gastro-omental artery. An LSG was performed on a 43-year-old woman (BMI = 46 kg/m2) without apparent surgical complications. Fifteen days later, she was admitted to the emergency department for hematemesis and symptoms of hemorrhagic shock. Abdominal computed tomography angiography revealed blood in the stomach, without a digestive leak, and active bleeding from a pseudo-aneurysm of the gastro-omental artery. An arterial embolisation was performed with the sandwich technique and angiographic guide wires and the placement of several detachable coils. The patient was discharged two days later. We demonstrated for the first time that post-LSG bleeding may involve a pseudo-aneurysm of the gastro-omental artery.

Our purpose was to explore the remission of insulin resistance after bariatric surgery to discover the mechanism of diabetes remission excluding dietary factors. A retrospective case control study was conducted on patients with type 2 diabetes, who underwent laparoscopic sleeve gastrectomy (LSG) or laparoscopic gastric bypass surgery (LGB) in Beijing Shijitan Hospital from April 1, 2012 to April 1, 2013. The laboratory and anthropometric data was analyzed pre-surgery and during a 2-year follow-up. HOMA-IR was calculated and evaluated. The two surgical procedures were compared. No significant difference in complete remission rate was observed between the two groups (LGB group: 62.1%, LSG group: 60.0%, p = 0.892). HOMA-IR was reduced to a stable level at the 3 rd month after surgery. The cut-off value of HOMA-IR was 2.38 (sensitivity: 0.938, specificity: 0.75) and 2.33 (sensitivity: 0.941, specificity: 0.778) respectively for complete remission after LSG or LGB surgery. Insulin resistance was improved while GLP-1 and Ghrelin was changed significantly in patients with type 2 diabetes prior to weight loss either in the LSG or LGB group. HOMA-IR decreased to less than the cut-off value at the 3 rd month and was closely related to complete remission. The mechanism of bariatric surgery was not due just to simply dietary factors or body weight loss but also the remission of insulin resistance.

Laparoscopic sleeve gastrectomy (LSG) is a highly successful approach to morbid obesity with low incidence of complications. The literature suggests a learning curve of 50-100 cases for attaining proficiency and reducing the complication rates for laparoscopic bariatric surgery. The aims of this paper were to review the literature of initial cases by bariatric surgeons worldwide and to report the experience of initial 50 cases of LSG by a novice bariatric team in a single center. The objective was to evaluate the outcomes for laparoscopic bariatric surgery in the first 50 patients by a novice team of bariatric surgeons in an already established bariatric surgery program with short-term follow-up. All surgeries were done by a new bariatric team who underwent laparoscopic fellowship training under a bariatric team with an experience of over 600 bariatric procedures. Fifty consecutive patients from March 2010 to January 2012 were offered LSG and followed up for a minimum of 6 months. Weight loss and comorbidity resolution were tabulated and assessed. Mean preoperative and postoperative BMIs were 46.6 and 35.7 kg/m2, respectively. There were no life threatening postoperative complications or mortality. The median percent excess weight loss was 50.3% at the end of 6 months. Comorbidity resolution values were 96% for obstructive sleep apnea, 89% for diabetes mellitus, and 87% for joint pains, among the most common comorbidities. LSG is effective in achieving weight loss and in improving comorbidities with minimal complications even at the hands of novice bariatric surgeons with good laparoscopic skills and adequate bariatric training.

Suprapancreatic lymph node (LN) dissection is critical for gastric cancer surgery. Until currently, a number of laparoscopic gastrectomy procedures have been performed in the same manner as open surgery procedures [3, 4, 6]. Using the characteristic of laparoscopic surgery, the authors developed a new technique of suprapancreatic LN dissection. After division of the duodenum, No. 8a LN is raised, and the surrounding tissue is dissected to identify the outmost layer of the nerves around the common hepatic artery. This layer can be dissected as the next step is headed for the root of the left gastric artery. Thin layers can be identified on the left and right sides of the artery. After this step, the LN dissection is performed toward both lateral sites, keeping the outmost layer of the nerves. At this stage, the surgeon should envision the "U" shape on the right side and the "V" shape on the left side for a superior performance. This technique was performed by the same surgeon for 20 consecutive patients with advanced gastric cancer. All the patients successfully underwent laparoscopic distal gastrectomy with D2 LN dissection. The mean number of regional LNs retrieved was 45.1 ± 13.5. The mean number of only LNs around the celiac artery (No. 7, 8a, 9, 11p, and 12a) was 17.8 ± 5.5. This was not less than reported previously [1, 2, 5]. The mean blood loss was 91.1 ml, and the mean operative time was 296.0 min. At this writing, all the patients are disease free after a mean follow-up period of 15.4 months. The nerves are thick and sturdy around the root of the left gastric artery. Additionally, the magnified and horizontal laparoscope view provides a straightforward approach and visibility to the layer. The authors believe that the "medial approach" is a straightforward method of suprapancreatic LN dissection in laparoscopic gastric cancer surgery.

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

The aim of this study was to analyze the oncological aspects of gastric cancer following laparoscopic gastrectomy with D2 lymphadenectomy (LG-D2). We retrospectively evaluated the long-term outcomes of 354 patients who underwent LG-D2 for primary gastric cancer. Recurrence patterns and predictors of peritoneal metastasis were analyzed. Median follow-up time was 43.8 months. Five-year overall survival rates for yp/pStages I, II, and III gastric cancer were 93.7, 78.5, and 42.2 %, respectively. Recurrence was observed in 86 patients. Peritoneal metastasis was the most frequent recurrence pattern (n = 51), followed by hepatic metastasis (n = 17). Lymphatic recurrence at distant sites was observed in 10 patients. No locoregional lymph node metastasis or local recurrence was seen. Nine of 51 cases of peritoneal recurrence were detected by probe laparoscopy. Peritoneal recurrence rates were significantly higher in yp/pT4 and yp/pN3 diseases compared with yp/pT ≤ 3 and yp/pN ≤ 2 diseases. Multivariate analyses demonstrated that yp/pT4, yp/pN3, tumor size ≥70 mm, vascular invasion, and undifferentiated tumors were predictors of peritoneal recurrence following LG-D2. Long-term outcomes of gastric cancer following LG-D2, including recurrence patterns and predictors of peritoneal metastasis, were comparable to those following open D2 gastrectomy. LG-D2 showed good local control. Probe laparoscopy after LG may be effective in detecting peritoneal recurrence, which is not determined with less invasive examinations, including a CT scan. Future large-scale prospective studies are desirable to evaluate not only surgical but also oncological benefits and safety of LG-D2 for advanced gastric cancer.

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

Microvascular dysfunction is a potential factor explaining the association of obesity, insulin resistance, and vascular damage in morbidly obese subjects. The purpose of the study was to evaluate possible determinants of microcirculatory improvement 1 year after laparoscopic sleeve gastrectomy (LSG) intervention. Thirty-seven morbidly obese subjects eligible for bariatric surgery were included in the study. Post-occlusive reactive hyperemia (PORH) of the forearm skin was measured as area of hyperemia (AH) by laser-Doppler flowmetry before LSG and after a 1-year follow-up. After intervention, we observed a significant reduction in BMI, HOMA index, HbA1c, and a significant increase of AH in all patients after surgery; this variation was significant only in those patients having insulin resistance or prediabetes/diabetes. Although significant correlation between the increase of AH and the reduction of both BMI, HOMA index, and HbA1c was observed, BMI was the only independent predictor of AH variation after LSG at the linear regression analysis. Our study shows that LSG intervention is correlated with a significant improvement in the microvascular function of morbidly obese subjects; this improvement seems to be related to the baseline degree of insulin-resistance and to the retrieval of insulin-sensitivity post-intervention.

Laparoscopic sleeve gastrectomy (LSG) is considered a primary bariatric surgery and is increasingly being performed worldwide; however, long-term data regarding the durability of this procedure are inadequate. Here, we report the long-term results of LSGs in comparison to those of gastric bypass surgeries. A prospectively collected bariatric database from Ming-Shen General Hospital was retrospectively studied. Five hundred nineteen morbidly obese patients (mean age 36.0 ± 9.1 years old (14-71), 74.6 % female, mean body mass index (BMI) 37.5 ± 6.1 kg/m(2)) underwent LSG as a primary bariatric procedure from 2006 to 2012 at our institute. The operative parameters, weight loss, laboratory data, and quality of life were followed. Another two matched groups of laparoscopic Roux-en-Y gastric bypass (RYGB) and laparoscopic single anastomosis (mini-) gastric bypass (SAGB) patients who were matched in terms of age, sex, and BMI were recruited for comparisons. The mean surgical time for LSG was 113.5 ± 31.3 min, and the mean blood loss was 49.1 + 100.9 ml. The rate of major complications was 1.6 %, and the average length of the postoperative stay was 3.0 ± 1.7 days. The operation times of the RYGB patients were longer than those of both the LSG and SAGB patients. The RYGB and SAGB patients experienced higher major complication rate than the LSG patients. The weight loss of the LSG patient at 5 years was 28.3 + 8.9 %, and the mean BMI was 27.1 + 4.3. The RYGB patients exhibited a 5-year weight loss similar to the LSG patients, and the SAGB patients exhibited greater weight loss than both of the other groups. Both the RYGB and SAGB patients exhibited significantly better glycemic control and lower blood lipids than the LSG patients, but the LSG patients exhibited a lesser micronutrient deficiency than the RYGB and SAGB groups. All three of the groups exhibited improved quality of life at 5 years after surgery, and there was no significant

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

Laparoscopic Roux-en-Y gastric bypass (LRYGB) and laparoscopic vertical sleeve gastrectomy (LVSG) have been proposed as cost-effective strategies to manage obesity-related chronic disease. The aim of this meta-analysis and systematic review was to compare the "early postoperative complication rate i.e. within 30-days" reported from randomized control trials (RCTs) comparing these two procedures. RCTs comparing the early complication rates following LVSG and LRYGB between 2000 and 2015 were selected from PubMed, Medline, Embase, Science Citation Index, Current Contents, and the Cochrane database. The outcome variables analyzed included 30-day mortality, major and minor complications and interventions required for their management, length of hospital stay, readmission rates, operating time, and conversions from laparoscopic to open procedures. Six RCTs involving a total of 695 patients (LVSG n = 347, LRYGB n = 348) reported on early major complications. A statistically significant reduction in relative odds of early major complications favoring the LVSG procedure was noted (p = 0.05). Five RCTs representing 633 patients (LVSG n = 317, LRYGB n = 316) reported early minor complications. A non-statically significant reduction in relative odds of 29 % favoring the LVSG procedure was observed for early minor complications (p = 0.4). However, other outcomes directly related to complications which included reoperation rates, readmission rate, and 30-day mortality rate showed comparable effect size for both surgical procedures. This meta-analysis and systematic review of RCTs suggests that fewer early major and minor complications are associated with LVSG compared with LRYGB procedure. However, this does not translate into higher readmission rate, reoperation rate, or 30-day mortality for either procedure.

Portomesenteric vein thrombosis (PMVT) is a rare but severe complication after laparoscopic bariatric surgery, with potentially serious consequences. We aimed to describe the incidence, clinical features, management, outcome, and midterm follow-up in patients with PMVT after laparoscopic sleeve gastrectomy (LSG). This retrospective and descriptive study included patients who underwent LSG between November 2009 and July 2015 and developed PMVT. The following data were analyzed: age, gender, body mass index (BMI), thrombosis risk factors, surgical technique, thromboembolic prophylaxis, primary surgery outcomes, clinical features, treatment, thrombophilia testing results, and follow-up findings, including imaging and endoscopic findings. A total of 1236 patients underwent LSG, and 5 (0.4 %) developed PMVT. The mean age was 34.4 years, and 3 patients were women. The mean BMI was 38.5 kg/m 2 . Two patients had received hormonal contraceptive treatment. Four patients had a history of smoking. All of the patients received anticoagulant treatment, and none required surgery. The mean hospitalization duration was 7.6 days. Two patients showed complete recanalization. One patient showed portal cavernomatosis on delayed images. Two patients had a positive thrombophilia test. No portal hypertension endoscopic findings were observed. PMVT is a rare complication, for which smoking was identified as a predominant risk factor. Early diagnosis and prompt anticoagulant therapy could lead to a dramatic decrease in the incidence of intestinal infarction, mortality, and extrahepatic portal hypertension in the near future. However, careful follow-up is necessary to evaluate the impact of PMVT on long-term patient outcomes.

Abdominoplasty is increasingly performed after weight loss surgery. However, performing a laparoscopic sleeve gastrectomy (LSG) after abdominoplasty poses technical challenges. The present study aimed to compare operative events and postoperative outcomes between LSG patients with and without a history of prior abdominoplasty. University hospital, Qatar. A case-control study was conducted on 2 groups of patients with (n = 33) and without (n = 69) prior abdominoplasty who underwent LSG. Patient demographics, baseline characteristics, as well as operative and postoperative events were compared between the 2 groups. A total of 102 patients with an average age of 39.6±7.7 years and body mass index (BMI) of 42.8±5.9 kg/m 2 were included. There were no significant differences between the 2 groups in terms of demographic characteristics, preoperative BMI, and co-morbidities. The number of ports required was significantly higher in the LSG patients with a history of prior abdominoplasty than in the nonabdominoplasty patients. The operation time was also significantly longer in the abdominoplasty patients than in the nonabdominoplasty patients (90.3±36.7 minutes versus 57.1±17.7 minutes; P<.0001). However, no significant differences were observed in terms of postoperative complications, length of hospital stay, and weight loss results. LSG after abdominoplasty is associated with longer operative times and the need for additional port placement to overcome the decreased working space. However, operative strategies should be considered to overcome the technical challenges during LSG in patients who underwent a prior abdominoplasty. Copyright © 2017. Published by Elsevier Inc.

Laparoscopic sleeve gastrectomy: More than a restrictive bariatric surgery procedure?

Sleeve gastrectomy (SG) is a restrictive bariatric surgery technique that was first used as part of restrictive horizontal gastrectomy in the original Scopinaro type biliopancreatic diversion. Its good results as a single technique have led to a rise in its use, and it is currently the second most performed technique worldwide. SG achieves clearly better results than other restrictive techniques and is comparable in some aspects to the Roux-en-Y gastric bypass, the current gold standard in bariatric surgery. These benefits have been associated with different pathophysiologic mechanisms unrelated to weight loss such as increased gastric emptying and intestinal transit, and activation of hormonal mechanisms such as increased GLP-1 hormone and decreased ghrelin. The aim of this review was to highlight the salient aspects of SG regarding its historical evolution, pathophysiologic mechanisms, main results, clinical applications and perioperative complications.

Dumping syndrome is a well-known adverse outcome after gastrectomy, but the precise clinical features have not been described. The aim of this study was to examine global aspects of dumping syndrome and to explore factors affecting the intensity of dumping syndrome in a large cohort using a newly developed integrated questionnaire, the Post-Gastrectomy Syndrome Assessment Scale (PGSAS)-45. Eligible questionnaires retrieved from 2,368 patients after 6 types of gastrectomy were analyzed. The incidence, intensity and number of symptoms of early general, early abdominal and late dumping syndrome were examined across various types of gastrectomy, and clinical factors affecting the intensity of each category of dumping syndrome were identified by multiple regression analysis. Dumping syndromes occurred most frequently and strongly in patients who underwent total gastrectomy with Roux-en-Y (TGRY), followed by proximal gastrectomy (PG), distal gastrectomy with Billroth-I, distal gastrectomy with Roux-en-Y, pylorus-preserving gastrectomy (PPG) and local resection (LR), in that order. Significant positive correlations among different categories of dumping syndromes were observed. TGRY, female sex, younger age, division of the celiac branch of the vagus nerve, PG and shorter postoperative period were independently related to worse dumping syndrome. Dumping syndromes were most common after TGRY and least common after PPG and LR among the various gastrectomy procedures. Type of gastrectomy and several clinical factors were related to the intensity of dumping syndrome. PGSAS-45 could offer a useful tool for evaluating dumping syndrome after gastrectomy. © 2015 S.

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

Despite the relatively slow start of laparoscopic pancreatectomy relative to other laparoscopic resections, an increasing number of these procedures are being performed around the world. Operations that were once considered impossible to perform laparoscopically, such as pancreaticoduodenectomy and central pancreatectomy are gaining momentum. Technology continues to improve, as does surgical experience and prowess. There are both enough experience and data (though retrospective) to confirm that LDP with or without spleen preservation appears to be a safe treatment for benign or noninvasive lesions of the pancreas. Based on the fact that LDP can be performed with similar or shorter operative times, blood loss, complication rates, and length of hospital stay than ODP, it can be recommended as the treatment of choice for benign and noninvasive lesions in experienced hands when clinically indicated. It is very difficult to make clear recommendations with regard to laparoscopic resection of malignant pancreatic tumors due to the lack of conclusive data. As long as margins are negative and lymph node clearance is within accepted standards, LDP appears to have no untoward oncologic effects on outcome. Certainly more data, preferably in the manner of a randomized clinical trial, are needed before additional recommendations can be made. Potential benefits of laparoscopic resection for cancer include the ability to inspect the abdomen and abort the procedure with minimal damage if occult metastases are identified. This does not delay the onset of palliative chemotherapy, which would be the primary treatment in that circumstance. In fact, there is evidence to suggest that there is a greater likelihood of receiving systemic therapy if a laparotomy is avoided in patients who have radiologically occult metastases. Patients may also undergo palliative laparoscopic gastric and biliary bypass if indicated. Faster wound healing may also translate into a shorter waiting time before

The aim of the study was to compare the clinical symptoms between Billroth II (B-II) and Roux-en-Y (R-Y) reconstruction after distal subtotal gastrectomy (DG) for gastric cancer. Surgery is the mainstay of curative treatment for gastric cancer. The technique for reconstruction after DG remains controversial. Both B-II and R-Y are popular methods. This is a prospective multicenter randomized controlled trial. From October 2008 to October 2014, 162 patients who underwent DG were randomly allocated to B-II (n = 81) and R-Y (n = 81) groups. The primary endpoint is Gastrointestinal (GI) Symptoms Score 1 year after surgery. We also compared the nutritional status, extent of gastritis on endoscopy, and quality of life after surgery between the 2 procedures at 1 year. Operative time was significantly shorter for B-II than for R-Y [mean difference 21.5 minutes, 95% confidence interval (95% CI) 3.8-39.3, P = 0.019]. The B-II and R-Y groups had a peri-operative morbidity of 28.4% and 33.8%, respectively (P = 0.500) and a 30-day mortality of 2.5% and 1.2%, respectively (P = 0.500). GI symptoms score did not differ between R-Y versus B-II reconstruction (mean difference -0.45, 95% CI -1.21 to 0.31, P = 0.232). R-Y resulted in a lower median endoscopic grade for gastritis versus B-II (mean difference -1.32, 95% CI -1.67 to -0.98, P < 0.001). We noted no difference in nutritional status (R-Y versus B-II mean difference -0.31, 95% CI -3.27 to 2.65, P = 0.837) and quality of life at 1 year between the 2 groups too. Although BII is associated with a higher incidence of heartburn symptom and higher median endoscopic grade for gastritis, BII and RY are similar in terms of overall GI symptom score and nutritional status at 1 year after distal gastrectomy.

Sleeve gastrectomy and the risk of leak: a systematic analysis of 4,888 patients.

2012-06-01

Sleeve gastrectomy has become a popular stand-alone bariatric procedure with comparable weight loss and resolution of comorbidities to that of laparoscopic gastric bypass. The simplicity of the procedure and the decreased long-term risk profile make this surgery more appealing. Nonetheless, the ever present risk of a staple-line leak is still of great concern and needs further investigation. An electronic literature search of MEDLINE database plus manual reference checks of articles published on laparoscopic sleeve gastrectomy for morbid obesity and its complications was completed. Keywords used in the search were "sleeve gastrectomy" OR "gastric sleeve" AND "leak." We analyzed 29 publications, including 4,888 patients. We analyzed the frequency of leak after sleeve gastrectomy and its associated risks of causation. The risk of leak after sleeve gastrectomy in all comers was 2.4%. This risk was 2.9% in the super-obese [body mass index (BMI) > 50 kg/m(2)] and 2.2% for BMI < 50 kg/m(2). Staple height and use of buttressing material did not affect leak rate. The use of a size 40-Fr or greater bougie was associated with a leak rate of 0.6% compared with those who used smaller sizes whose leak rate was 2.8%. Leaks were found at the proximal third of the stomach in 89% of cases. Most leaks were diagnosed after discharge. Endoscopic management is a viable option for leaks and was documented in 11% of cases as successful. Sleeve gastrectomy has become an important surgical option for the treatment of the ever growing morbidly obese population. The risk of leak is low at 2.4%. Attention to detail specifically at the esophagogastric junction cannot be stressed enough. Careful patient selection (BMI < 50 kg/m(2)) and adopting the use of a 40-Fr or larger bougie may decrease the risk of leak. Vigilant follow-up during the first 30 days is critical to avoid catastrophe, because most leaks will happen after patient discharge.

The purpose of this study was to evaluate the relationship between technical performance and patient outcomes in laparoscopic gastric cancer surgery. Laparoscopic gastrectomy for cancer is an advanced procedure with high rate of postoperative morbidity and mortality. Many variables including patient, disease, and perioperative management factors have been shown to impact postoperative outcomes; however, the role of surgical performance is insufficiently investigated. A retrospective review was performed for all patients who had undergone laparoscopic gastrectomy for cancer at 3 teaching institutions between 2009 and 2015. Patients with available, unedited video-recording of their procedure were included in the study. Video files were rated for technical performance, using Objective Structured Assessments of Technical Skills (OSATS) and Generic Error Rating Tool instruments. The main outcome variable was major short-term complications. The effect of technical performance on patient outcomes was assessed using logistic regression analysis with backward selection strategy. Sixty-one patients with available video recordings were included in the study. The overall complication rate was 29.5%. The mean Charlson comorbidity index, type of procedure, and the global OSATS score were included in the final predictive model. Lower performance score (OSATS ≤29) remained an independent predictor for major short-term outcomes (odds ratio 6.49), while adjusting for comorbidities and type of procedure. Intraoperative technical performance predicts major short-term outcomes in laparoscopic gastrectomy for cancer. Ongoing assessment and enhancement of surgical skills using modern, evidence-based strategies might improve short-term patient outcomes. Future work should focus on developing and studying the effectiveness of such interventions in laparoscopic gastric cancer surgery.

The optimal surgical procedure for distal gastrectomy with Roux-en-Y reconstruction (DGRY) remains to be determined. Recently, a self-report assessment instrument, the Postgastrectomy Syndrome Assessment Scale-45 (PGSAS-45), was compiled to evaluate symptoms, the living status and the quality of life of patients who have undergone gastrectomy. We used this scale to evaluate procedures used for DGRY. The subjects included 475 patients who underwent DGRY for stage IA/IB gastric cancer. We evaluated whether the size of the remnant stomach, length of the Roux limb, reconstruction route and anastomotic procedure affected the patients' symptoms, living status and quality of life assessed using the PGSAS-45. Patients with a residual stomach of more than half had significantly worse esophageal reflux scores than the patients with a smaller residual stomach (P = 0.0462); a residual stomach of one-third or one-fourth was favorable. A shorter length of the Roux limb was shown to be preferable to a longer Roux limb based on the results of the PGSAS-45. In addition, antecolic reconstruction and the anastomotic procedure using a linear stapler were found to be more favorable. The size of the remnant stomach and the length and route of the Roux limb significantly influence the patient-reported DGRY outcomes.

Surgery appears to be the best treatment option for a chronic fistula after laparoscopic sleeve gastrectomy (LSG). Conservative procedures (conversion into a Roux-en-Y gastric bypass, Roux-limb placement) have proven their feasibility and efficacy, but an open total gastrectomy (TG) is sometimes required in challenging situations. To assess outcomes from 12 consecutive patients who underwent surgery for a post-sleeve gastrectomy chronic fistula (PSGCF) between January 2004 and February 2012. University public hospital, France. Patients with a PSGCF who underwent surgery were included in this retrospective study. Mortality, morbidity (i.e., Clavien-Dindo score), weight loss, and nutritional status were assessed. Twelve of 57 patients (21%) with a post-LSG leak developed a PSGCF. There were 3 men (25%). Mean age was 39±9 years and mean preoperative body mass index was 35±5 kg/m 2 . All 12 patients underwent an open total gastrectomy with an esojejunostomy (TG). Conservative procedures were considered but not possible. The mean follow-up period was 38±11 months. The mean delay between LSG and TG was 12±6 months. Intraoperative discovery of multiple (>2) gastric fistulas was reported in 9 patients (75%). There were no deaths, but morbidity rate was 50%. Early postoperative fistula occurred in 3 patients (anastomosis n = 1, duodenal stump n = 2). None of these patients required further surgery. The median healing time of the fistula was 37 days (range 24-53). Promising results from weight loss and nutritional status were found at the end of the follow-up. A salvage open TG is a well-tolerated and reproducible salvage procedure for cases of a PSGCF, when conservative procedures are not possible. Copyright © 2016 American Society for Bariatric Surgery.

AIM: To evaluate the feasibility and safety of full robot-assisted gastrectomy with intracorporeal robot hand-sewn anastomosis in the treatment of gastric cancer. METHODS: From September 2011 to March 2013, 110 consecutive patients with gastric cancer at the authors’ institution were enrolled for robotic gastrectomies. According to tumor location, total gastrectomy, distal or proximal subtotal gastrectomy with D2 lymphadenectomy was fully performed by the da Vinci Robotic Surgical System. All construction, including Roux-en-Y jejunal limb, esophagojejunal, gastroduodenal and gastrojejunal anastomoses were fully carried out by the intracorporeal robot-sewn method. At the end of surgery, the specimen was removed through a 3-4 cm incision at the umbilicus trocar point. The details of the surgical technique are well illustrated. The benefits in terms of surgical and oncologic outcomes are well documented, as well as the failure rate and postoperative complications. RESULTS: From a total of 110 enrolled patients, radical gastrectomy could not be performed in 2 patients due to late stage disease; 1 patient was converted to laparotomy because of uncontrollable hemorrhage, and 1 obese patient was converted due to difficult exposure; 2 patients underwent extra-corporeal anastomosis by minilaparotomy to ensure adequate tumor margin. Robot-sewn anastomoses were successfully performed for 12 proximal, 38 distal and 54 total gastrectomies. The average surgical time was 272.52 ± 53.91 min and the average amount of bleeding was 80.78 ± 32.37 mL. The average number of harvested lymph nodes was 23.1 ± 5.3. All specimens showed adequate surgical margin. With regard to tumor staging, 26, 32 and 46 patients were staged as I, II and III, respectively. The average hospitalization time after surgery was 6.2 d. One patient experienced a duodenal stump anastomotic leak, which was mild and treated conservatively.

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

CT-Guided Percutaneous Drainage of Infected Collections Due to Gastric Leak After Sleeve Gastrectomy for Morbid Obesity: Initial Experience

DOE Office of Scientific and Technical Information (OSTI.GOV)

Kelogrigoris, M., E-mail: kelogre.mic@hotmail.com; Sotiropoulou, E.; Stathopoulos, K.

This study was designed to evaluate the efficacy and safety of computed tomography (CT)-guided drainage in treating infected collections due to gastric leak after laparoscopic sleeve gastrectomy for morbid obesity. From January 2007 to June 2009, 21 patients (9 men and 12 women; mean age, 39.2 (range, 26-52) years) with infected collections due to gastric leak after laparoscopic sleeve gastrectomy for morbid obesity underwent image-guided percutaneous drainage. All procedures were performed using CT guidance and 8- to 12-Fr pigtail drainage catheters. Immediate technical success was achieved in all 21 infected collections. In 18 of 21 collections, we obtained progressive shrinkagemore » of the collection with consequent clinical success (success rate 86%). In three cases, the abdominal fluid collection was not resolved, and the patients were reoperated. Among the 18 patients who avoided surgery, 2 needed replacement of the catheter due to obstruction. No major complications occurred during the procedure. The results of our study support that CT-guided percutaneous drainage is an effective and safe method to treat infected abdominal fluid collections due to gastric leak in patients who had previously underwent laparoscopic sleeve gastrectomy for morbid obesity. It may be considered both as a preparatory step for surgery and a valuable alternative to open surgery. Failure of the procedure does not, however, preclude a subsequent surgical operation.« less

Laparoscopic sleeve gastrectomy and gastroesophageal reflux

PubMed Central

Stenard, Fabien; Iannelli, Antonio

2015-01-01

Bariatric surgery is the only effective procedure that provides long-term sustained weight loss. Sleeve gastrectomy (SG) has emerged over the last few years to be an ideal bariatric procedure because it has several advantages compared to more complex bariatric procedures, including avoiding an intestinal bypass. However, several published follow-up studies report an increased rate of gastroesophageal reflux (GERD) after a SG. GERD is described as either de novo or as being caused by aggravation of preexisting symptoms. However, the literature on this topic is ambivalent despite the potentially increased rate of GERDs that may occur after this common bariatric procedure. This article reviews the mechanisms responsible for GERD in obese subjects as well as the results after a SG with respect to GERD. Future directions for clinical research are discussed along with the current surgical options for morbidly obese patients with GERD and undergoing bariatric surgery. PMID:26420961

Robotic technology is increasingly prevalent in bariatric surgery, yet there are national deficiencies in exposure of surgical residents to robotic techniques. The purpose of this study is to accurately characterize the perioperative outcomes of a resident teaching model using the robotic-assisted sleeve gastrectomy. University Hospital. We identified 411 consecutive patients who underwent robotic sleeve gastrectomy at our institution from a prospectively maintained administrative database. Perioperative morbidity, operative time, and supply cost of the procedure were analyzed. Mean operative time was 96.4±24.9 minutes; mean robot usage time was 63.9 minutes (range 30.0-122.0 min). Ninety-day morbidities included reoperation (0.72%), major bleeding complications (0.48%), staple line leak (0.24%), stricture (0.97%), need for blood transfusion (3.86%), surgical site infection (1.69%), deep vein thrombosis (0.48%), and pulmonary embolism (0.48%). Mortality was nil. The resident cohort achieved operative time plateaus after five consecutive cases. Subset analysis for fiscal year 2014 demonstrated significantly increased supply cost for robotic sleeve gastrectomy compared with its laparoscopic equivalent. Robotic-assisted sleeve gastrectomy can be instituted as a model for resident robotic education with rates of morbidity and operative times equivalent to historical laparoscopic controls. The robot's enhanced ergonomics and its opportunity for resident education must be weighed against its increased supply cost. Copyright © 2016 American Society for Bariatric Surgery.

Laparoscopic sleeve gastrectomy (LSG) is gaining acceptance as the preferred option for treating obesity. Risks of leak and subsequent fistula after sleeve gastrectomy still present significant concerns in clinical practice. This current series presents unusual fistulas post-LSG and their surgical management. The series presents chronic leaks that have progressed into fistulas. Three patients with fistulas are presented: gastrocolic, gastropleural, and gastrosplenic. Surgical intervention was warranted in all cases with en-bloc resection of the fistula with subtotal gastrectomy and Roux-en-Y esophagojejunostomy reconstruction. A subtotal colectomy with ileo-descending colon anastomosis was additionally necessary in the gastrocolic patient. The patients with the gastropleural and gastrosplenic fistulas were discharged home on postoperative Day 6 and Day 7, respectively. The patient with the gastrocolic fistula had an extended postoperative hospital course and was discharged home on postoperative Day 35. All cases were negative for staple line leaks. To date, the fistulas healed with no recurrence. En-bloc resection of the fistula with proximal gastrectomy and Roux-en-Y esophagojejunostomy (PGRYEJ) is a surgical option to treat chronic staple line leakage when non-operative therapy is rendered ineffective. Adequate preoperative planning with optimization of nutritional status and control of local and systemic sepsis is paramount for ultimate success. A symptomatic leak requires immediate operation regardless of the time interval between the primary sleeve operation and appearance of the leak.

Postoperative leak is a serious complication of bariatric surgery and often results in significant morbidity and mortality. Stent placement is a less invasive alternative to surgery for the treatment of bariatric surgical leak. We evaluated the efficacy and complications of covered self-expandable metal stents (SEMS) in the treatment of post-bariatric surgical leak. We retrospectively reviewed patients who underwent stent placement for leak after bariatric surgery. Leak was diagnosed by upper gastrointestinal series or was visualized during the endoscopy. We examined the timing of stent placement, size of the leak, stent migration and its complications, total stent treatment duration, and treatment outcome. Between January 2011 and April 2015, seven patients underwent covered SEMS placement for leak after bariatric surgery, including laparoscopic sleeve gastrectomy (LSG) (n = 5) and laparoscopic loop duodenojejunal bypass with sleeve gastrectomy (LDJB-SG) (n = 2). A stent was placed in one patient for infection control and bridging to revisional surgery. Among the other six patients, one patient who received stent placement one year after leak diagnosis failed to achieve leak closure, and five patients with early stent placement achieved leak closure. Three patients with small leak achieved leak closure more quickly. Stent migration was found in six patients, and associated ulcers occurred in five patients. We conclude that stenting is effective in the management of staple-line leaks following LSG and LDJB-SG. Stent migration and associated ulcers are common after stent placement. Early stent removal can be achieved in patients with small leaks. Copyright © 2017. Published by Elsevier Taiwan.

During surgery for choledochal cyst (CC), any intrapancreatic CC (IPCC) must also be excised to prevent postoperative pancreatitis and stone formation. We report our technique for laparoscopic total IPCC excision (n = 16; mean age 6.0 years). We insert a fine ureteroscope with a light source into the opened CC through an extra 3.9-mm trocar placed in the epigastrium through a minute incision to identify the pancreatic duct orifice. By pulling the end of the ureteroscope emerging from the trocar gently to withdraw the tip from the pancreatic duct to where distal dissection was ceased under laparoscopic view, the IPCC can be measured. If longer than 5 mm, the distal CC is dissected further caudally until it is less than 5 mm. For accuracy, the distal CC is elevated with a suture that is exteriorized and clamped to provide constant traction. The IPCC was able to be measured in 11/16 (68 %). Initial lengths measured were 3-10 mm (5.2 ± 2.7 mm). Final IPCC were all 5 mm or less. Surgery was uncomplicated without any pancreatic duct injury and postoperative recovery was unremarkable. Follow-up MRI at 32 months showed no IPCC in any case. Measuring the IPCC enables total CC excision, thus reducing the potential for postoperative complications.

Gastric carcinomas are common malignancies in southern India and distal stomach remains the commonest site in low socio economic groups. Surgery still remains an important modality of treatment to achieve local control and also relieve obstructive symptoms. In this study we investigated the feasibility of performing a gastrectomy and billroth-1 type of anastomosis in a rural cancer center setting, with parameters like adequacy of margins, ease of anastomosis and its functional results were analysed. Eight patients presenting to a rurally based cancer center underwent a distal gastrectomy and billroth-1 type of anastomosis for continuity restoration. All the patients had adequate proximal and distal marg. The surgical time varied between-hrs. The anastomosis was constructed without any tension on bowel ends in all patients. The average time to start oral feeds varied between- None of the patients showed symptoms of bile reflux nor dumping. The average hospital stay varied between. Billroth-1 anastomosis is a physiologically more natural way of restoring continuity following a gastrectomy and it is a procedure which would be technically more simpler and decrease per and post operative complications and allow speedier post operative recovery following surgery on distal gastric cancers.

Various reconstructions of the gastro-intestinal tract have been described in the past after distal gastrectomy. Among these, a Billroth II (BII) anastomosis can be performed with the addition of the Omega entero-enterostomy that may theoretically reduce the alkaline reflux. Given the significant complications associated with this procedure such as biliary reflux, marginal ulceration, and afferent loop syndrome, a revision into a Roux-en-Y anatomy is generally recommended. A 73-year-old healthy male was referred to our foregut surgery service for treatment of severe biliary gastritis. The patient previously underwent an open distal gastrectomy with a BII reconstruction followed by a Braun-type entero-enterostomy 6 months later. His main complaint was worsening daily biliary reflux with constant regurgitations, which were non-responsive to medical treatment. The preoperative endoscopy confirmed the diagnosis of severe biliary gastritis secondary to alkaline reflux. The distance between the gastro-jejunostomy and the Braun anastomosis was also measured with a pediatric colonoscope and the length of the efferent limb was estimated to be 80 cm. Identification of the afferent and efferent limb was complicated by the patient's incomplete intestinal malrotation with the angle of Treitz being present in the right hypochondrium. Intra-operative gastroscopy enabled visualization of the jejuno-jejunostomy and ensured correct interpretation of the anatomy. Subsequently, resection of the afferent limb completed the revision into a Roux-en-Y anatomy. The patient recovered well after the surgery and was discharged home on post-operative day 2. At 6 months follow-up, the patient's reflux symptoms have completely disappeared. BII reconstruction with or without Braun entero-enterostomy is a classic historical option following distal gastrectomy. Surgical revision of a BII into a Roux-en-Y anatomy is a good solution for severe biliary reflux and other long-term complications

Most risk adjustment approaches adjust for patient comorbidities and the primary procedure. However, procedures done at the same time as the index case may increase operative risk and merit inclusion in adjustment models for fair hospital comparisons. Our objectives were to evaluate the impact of surgical complexity on postoperative outcomes and hospital comparisons in gastric cancer surgery. Patients who underwent gastric resection for cancer were identified from a large clinical dataset. Procedure complexity was characterized using secondary procedure CPT codes and work relative value units (RVUs). Regression models were developed to evaluate the association between complexity variables and outcomes. The impact of complexity adjustment on model performance and hospital comparisons was examined. Among 3,467 patients who underwent gastrectomy for adenocarcinoma, 2,171 operations were distal and 1,296 total. A secondary procedure was reported for 33% of distal gastrectomies and 59% of total gastrectomies. Six of 10 secondary procedures were associated with adverse outcomes. For example, patients who underwent a synchronous bowel resection had a higher risk of mortality (odds ratio [OR], 2.14; 95% CI, 1.07-4.29) and reoperation (OR, 2.09; 95% CI, 1.26-3.47). Model performance was slightly better for nearly all outcomes with complexity adjustment (mortality c-statistics: standard model, 0.853; secondary procedure model, 0.858; RVU model, 0.855). Hospital ranking did not change substantially after complexity adjustment. Surgical complexity variables are associated with adverse outcomes in gastrectomy, but complexity adjustment does not affect hospital rankings appreciably. Copyright © 2015 Elsevier Inc.

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

Laparoscopic sleeve gastrectomy (LSG) is a popular stand-alone bariatric surgery, despite a paucity of long-term data. Hence, this study is to report the long-term outcome of LSG as primary bariatric procedure and the result of revisional surgery. With retrospective analysis of a prospective bariatric database, participants who defaulted clinic follow-up were interviewed by telephone. A total of 667 LSG was performed as primary bariatric procedure (2006-2012) with mean age of 34.5 ± 9.7 years old, female 74.7%, mean body mass index (BMI) 37.3 ± 8.1 kg/m(2). A 36-F bougie was used for all cases. There were 61 patients available with long-term data. The weight loss outcome at 1 year, 2 years, 3 years, 4 years, and 5 years showed a mean BMI 26.3, 25.2, 25.3, 27.1, and 26.2 with mean excess weight loss (EWL) 76.0%, 79.6%, 77.3%, 73.4%, and 72.6% respectively. However, 17% patients developed de novo gastro-esophageal reflux disease (GERD). Eighteen patients (2.2%) needed surgical revisions due to weight regain (n = 6), persistent type 2 diabetes mellitus (T2DM; n = 2), stricture (n = 2), and GERD (n = 8). The revision resulted in an additional mean excess weight loss of 23.8% with mean BMI 24.9 kg/m(2) at 6 months postoperatively. There was a 23.7% mean reduction of HbA1c with one patient who was in complete diabetic remission at 1 year. Our results showed LSG is a durable bariatric procedure with > 70% EWL at 5 years despite a high incidence of GERD. The need for revision of LSG is low and mainly for GERD. Copyright © 2015.

Introduction According to the Brazilian National Institute of Cancer, gastric cancer is the third leading cause of death among men and the fifth among women in Brazil. Surgical resection is the only potentially curative treatment. The most serious complications associated with surgery are fistulas and dehiscence of the jejunal-esophageal anastomosis. Hiatal hernia refers to herniation of elements of the abdominal cavity through the esophageal hiatus of the diaphragm, though this occurrence is rarely reported as a complication in gastrectomy. Case Report A 76-year-old man was diagnosed with intestinal-type gastric adenocarcinoma. He underwent a total laparoscopic-assisted gastrectomy and D2 lymphadenectomy on May 19, 2015. The pathology revealed a pT4pN3 gastric adenocarcinoma. The patient became clinically stable and was discharged 10 days after surgery. He was subsequently started on adjuvant FOLFOX chemotherapy; however, 9 days after the second cycle, he was brought to the emergency room with nausea and severe epigastric pain. A CT scan revealed a hiatal hernia with signs of strangulation. The patient underwent emergent repair of the hernia and suffered no postoperative complications. He was discharged from the hospital 9 days after surgery. Conclusion Hiatal hernia is not well documented, and its occurrence in the context of gastrectomy is an infrequent complication.

Obesity in young people is one of the most serious public health problems worldwide. Moreover, the mechanisms preventing obese adolescents from losing and maintaining weight loss have been elusive. Laparoscopic sleeve gastrectomy (LSG) is successful at achieving long-term weight loss in patients across all age groups, including children and adolescents. Anecdotal clinical observation as well as evidence in rodents suggests that LSG induces a shift in preference of sugary foods. However, it is not known whether this shift is due to a change in the threshold for gustatory detection of sucrose, or whether LSG induces behavioral change without affecting the gustatory threshold for sugar. The objective of this study was to determine whether adolescents who undergo LSG experience a change in their threshold for detecting sweet taste. We studied the sucrose detection threshold of 14 obese adolescents (age 15.3 ± 0.5 years, range 12-18) who underwent LSG 2 weeks before surgery and at 12 and 52 weeks after surgery. Matched non-surgical subjects were tested on two occasions 12 weeks apart to control for potential learning of the test that may have confounded the results. Seven sucrose concentrations were used and were tested in eight blocks with each block consisting of a random seven sucrose and seven water stimuli. The subjects were asked to report whether the sample contained water or not after they tasted 15 ml of the fluid for 10 s. The bodyweight of the LSG group decreased from 136.7 ± 5.4 to 109.6 ± 5.1 and 86.5 ± 4.0 kg after 12 and 52 weeks, respectively (p < 0.001). There was no significant difference after surgery in taste detection threshold of patients after LSG (p = 0.60), and no difference was observed comparing the taste detection threshold of the LSG group with the non-surgical controls (p = 0.38). LSG did not affect the taste detection threshold for sucrose, suggesting that the shift in preference for sugary foods may be due to

Purpose Although laparoscopic Heller myotomy and Dor fundoplication (LHD) is widely performed to address achalasia, little is known about the learning curve for this technique. We assessed the learning curve for performing LHD. Methods Of the 514 cases with LHD performed between August 1994 and March 2016, the surgical outcomes of 463 cases were evaluated after excluding 50 cases with reduced port surgery and one case with the simultaneous performance of laparoscopic distal partial gastrectomy. A receiver operating characteristic (ROC) curve analysis was used to identify the cut-off value for the number of surgical experiences necessary to become proficient with LHD, which was defined as the completion of the learning curve. Results We defined the completion of the learning curve when the following 3 conditions were satisfied. 1) The operation time was less than 165 minutes. 2) There was no blood loss. 3) There was no intraoperative complication. In order to establish the appropriate number of surgical experiences required to complete the learning curve, the cut-off value was evaluated by using a ROC curve (AUC 0.717, p < 0.001). Finally, we identified the cut-off value as 16 surgical cases (sensitivity 0.706, specificity 0.646). Conclusion Learning curve seems to complete after performing 16 cases. PMID:28686640

Laparoscopic sleeve gastrectomy (LSG) is gaining popularity worldwide. This retrospective cohort study evaluated the outcomes of a large cohort of patients with obesity who underwent LSG in a Bariatric Center of Excellence. All consecutive patients who underwent LSG between July 2013 and April 2016 were identified retrospectively. Preoperative and postoperative variables and comorbidities were recorded. The study consisted of 750 patients. Their mean age was 37.4 years; 72% were women, and the mean body mass index was 42.8 kg/m. The most common preoperative comorbidities were diabetes (23.3%), hyperlipidemia (21.9%), hypertension (21.1%), and obstructive sleep apnea (21.1%). The rates of comorbidity resolution during follow-up were 80.6%, 74.4%, 82.9%, and 94.3%, respectively. The percentage average excess weight loss 1, 3, and 6 months and 1 and 2 years after surgery was 29.4%±11.3%, 54.4%±17.7%, 76.9%±20.9%, 85.5%±23.6%, and 89.7%±27.6%, respectively. There was no mortality. LSG effectively and safely induced weight loss and comorbidity resolution.

AIM: To describe the application of complete robotic gastrectomy with transvaginal specimen extraction (TVSE) for gastric cancer patients. METHODS: Between July and November 2014, eight female patients who were diagnosed with gastric adenocarcinoma underwent a TVSE following a full robot-sewn gastrectomy. According to the tumor location, the patients were allocated to two different groups; two patients received robotic total gastrectomy with TVSE and the other six received robotic distal gastrectomy with TVSE. RESULTS: Surgical procedures were successfully performed in all eight cases without conversion. The mean age was 55.3 (range, 42-69) years, and the mean body mass index was 23.2 (range, 21.6-26.0) kg/m2. The mean total operative time and blood loss were 224 (range, 200-298) min and 62.5 (range, 50-150) mL, respectively. The mean postoperative hospital stay was 3.6 (range, 3-5) d. The mean number of lymph nodes resected was 23.6 (range, 17-27). None was readmitted within 30 d of postoperation. During the follow-up, no stricture developed nor was any anastomotic leakage detected. CONCLUSION: It is possible to perform a TVSE following a full robot-sewn gastrectomy with standard D2 lymph node resection for female gastric cancer patients. PMID:26715817

Laparoscopic sleeve gastrectomy (LSG) is one of the most frequently performed bariatric surgery interventions because of its safety and efficacy. Nevertheless, concerns have been raised on its detrimental effect on patient nutritional state that can ultimately lead to the loss of fat-free mass (FFM). There is interest in identifying predictors for the early identification of patients at risk of this highly unwanted adverse because they could benefit of nutritional preventive interventions. Therefore, we investigated whether anthropometric parameters, body composition or resting energy expenditure (REE) measured before surgery could predict FFM loss 1 year after LSG. Study design was retrospective observational. We retrieved data on body weight, BMI, body composition and REE before and 1 year after LSG from the medical files of 36 patients operated on by LSG at our institutions. Simple regression, the Oldham's method and multilevel analysis were used to identify predictors of FFM loss. Averaged percentage FFM loss 1 year after LSG was 17.0 ± 7.7% with significant differences between sexes (20.8 ± 6.6 in males and 12.2 ± 6.1% in females, p < 0.001). FFM loss was strongly predicted by pre-surgery FFM and this effect persisted also after correcting for the contribution of sex. High FFM values before surgery predict a more severe FFM loss after LSG. This factor could also account for the higher FFM loss in men than in women. Our finding could help in the early identification of patient requiring a nutritional support after LSG.

Totally laparoscopic gastrectomy (TLG) using intracorporeal anastomosis has gradually become mature thanks to the advancements of laparoscopic surgical instruments and the accumulation of operative experience. The goal of this study is to review our institution's experience with TLG for the treatment of gastric cancer. A retrospective study was conducted to examine the short-term outcomes of TLG using intracorporeally stapler or hand-sewn anastomosis performed at Sir Run Run Shaw Hospital between March 2007 and June 2015. The details of intracorporeal anastomosis were described, and the clinicopathological data, surgical outcomes, and postoperative complications were evaluated. Four hundred seventy-eight patients were included in the study. Generally speaking, the patients could be divided into stapler or hand-sewn groups according to whether intracorporeal anastomosis was performed by only hand-sewn technique (n = 97) or only stapling devices (n = 381). For overall patients, the mean operation time and anastomotic time were 225.7 and 30.0 min, respectively. Postoperative complications were observed in 65 patients. All of the patients recovered well without perioperative death by conservative or surgical management. TLG using intracorporeally stapler or hand-sewn anastomosis is a reasonable option for the treatment of gastric cancer, with early data showing acceptable perioperative outcomes.

The laparoscopic sleeve gastrectomy is now the most common bariatric operation in the United States and has become an established procedure in the armamentarium of the bariatric surgeon. However, this has happened without the strong support of long-term outcomes data, namely the rate of revision and durability of the weight loss. Newly published data from around the world are starting to show alarming trends in these 2 areas. This paper will examine the published and presented data with at least a 7-year follow-up. This is a meta-analysis on published data with at least 7 years of follow-up from the laparoscopic sleeve gastrectomy. Online published articles. We performed a meta-analysis of publications with at least 7 years of follow-up with the keywords "laparoscopic, bariatric, sleeve gastrectomy, sleeve, long-term, long, term, results, follow-up, follow up, conversion, 7 years, 8 years, 9 years, 10 years, 11 years." We queried the PubMed, MEDLINE, and ClinicalKey search engines, which included abstracts as well. The I 2 statistic was used to determine the heterogeneity across the studies. In presence of heterogeneity, a random effect model using the Dersimonian and Laird method was used to estimate the pooled estimates. The results were summarized using effect size along with a 95% confidence interval (CI). Meta-regression was also used to assess the effect of body mass index and follow-up years on the incidence of recidivism at ≥7 years. Nine cohort studies met the inclusion criteria, with a total of 2280 patients included initially. Only 652 patients had completed ≥7 years of follow-up. At ≥7 years, the long-term weight recidivism rate was estimated to be 27.8% (I 2 = .60%; 95% CI: 22.8%-32.7%) with a range of 14% to 37%. The overall revision rate was estimated to be 19.9% (I 2 = 93.8%; 95% CI: 11.3%-28.5%). This was broken down into 13.1% (I 2 = 93.8%; 95% CI: 5.6%-20.6%) due to weight regain (5 studies) and 2.9% (I 2 = 60.8%; 95% CI: 1%-4.9%) due to

After gastrectomy or esophagectomy, esophagogastrostomy and esophagojejunostomy are commonly used for reconstruction. Water-soluble contrast swallow is often used as a routine screening to exclude anastomotic leakage during the first postoperative week. In this retrospective study, the sensitivity and specificity of oral water-soluble contrast swallow for the detection of anastomotic leakage and its clinical symptoms were analysed. Records of 104 consecutive total gastrectomies and distal esophagectomies were analysed. In all cases, upper gastrointestinal contrast swallow with the use of a water-soluble contrast agent was performed on the 5 th postoperative day. Extravasation of the contrast agent was defined as anastomotic leakage. When anastomotic insufficiency was suspected but no extravasation was present, a computed tomography (CT) scan and upper endoscopy were performed. Oral contrast swallow detected 7 anastomotic leaks. Based on CT-scans and upper endoscopy, the true number of anastomotic leakage was 15. The findings of the oral contrast swallow were falsely positive in 4 and falsely negative in 12 patients, respectively. The sensitivity and specificity of the oral contrast swallow was 20% and 96%, respectively. Routine radiological contrast swallow following total gastrectomy or distal esophagectomy cannot be recommended. When symptoms of anastomotic leakage are present, a CT-scan and endoscopy are currently the methods of choice.

Ureter injuries are uncommon but dreaded complications in gynecologic surgery and a frequent cause of conversion to laparotomy. Recently, a few papers reported the repair of gynecologic ureteral injuries using laparoscopy with encouraging results. In these case reports, we aimed to present two laparoscopically repaired ureter injuries during total laparoscopic hysterectomies (TLH). In the first case, the ureter was transected during the dissection of the cardinal ligament, approximately 7 to 8 cm distal to the ureterovesical junction (UVJ), and in the second case, it was damaged approximately 10 cm distal to the UVJ. Both transections were identified during surgery. The injured ureter was repaired without converting to laparotomy or additional trocar insertion. Ureteroureterostomy was performed in both cases uneventfully. Although ureteric injury is a rare complication during TLH, it can be managed by the same surgeon laparoscopically during the same procedure. PMID:29085711

Laparoscopic Roux-en-Y gastric bypass (LRYGB) and laparoscopic vertical sleeve gastrectomy (LVSG) have been proposed as cost-effective strategies to manage morbid obesity. The aim of this meta-analysis was to compare the postoperative weight loss outcomes reported in randomized control trials (RCTs) for LVSG versus LRYGB procedures. RCTs comparing the weight loss outcomes following LVSG and LRYGB in adult population between January 2000 and November 2015 were selected from PubMed, Medline, Embase, Science Citation Index, Current Contents, and the Cochrane database. The review was prepared in accordance with Preferred Reporting of Systematic Reviews and Meta-Analyses (PRISMA). Nine unique RCTs described over 10 publications involving a total of 865 patients (LVSG, n=437; LRYGB, n=428) were analyzed. Postoperative follow-up ranged from 3 months to 5 years. Twelve-month excess weight loss (EWL) for LVSG ranged from 69.7% to 83%, and for LRYGB, ranged from 60.5% to 86.4%. A number of studies reported slow weight gain between the second and third years of postoperative follow-up ranging from 1.4% to 4.2%EWL. This trend was seen to continue to 5 years postoperatively (8% to 10%EWL) for both procedures. In conclusion, LRYGB and LVSG are comparable with regards to the weight loss outcomes in the short term, with LRYGB achieving slightly greater weight loss. Slow weight recidivism is observed after the first postoperative year following both procedures. Long-term reporting of outcomes obtained from well-designed studies using intention-to-treat analyses are identified as a major gap in the literature at present.

Leak or Fistula After Sleeve Gastrectomy: Treatment with Pigtail Drain by the Rendezvous Technique.

PubMed

Soufron, Jacques

2015-10-01

After a sleeve gastrectomy, a leak or fistula is a serious complication. Laparoscopic drainage, drainage under US or CT scan control, or endoscopic insertion of a stent can be used, but a major re-operation is sometimes unavoidable. Endoscopic drainage with a pigtail catheter could give more success and fewer complications, but the insertion of the drain is not always possible nor does it always provide a perfect drainage. If a laparoscopic second look appears necessary, it is possible to insert a pigtail drain laparoscopically, but under endoscopic control, ensuring a correct positioning of the drain both in the peritoneal cavity and in the gastric tube. This simultaneous "rendezvous" technique could combine in this situation the advantages of purely surgical techniques and of purely endoscopic or image-guided techniques.

Established systems for grading postoperative complications do not change the assigned grade when multiple interventions or readmissions are required to manage a complication. Studies using these systems may misrepresent outcomes for the surgical procedures being evaluated. We define a quality outcome for distal pancreatectomy (DP) and use this metric to compare laparoscopic distal pancreatectomy (LDP) to open distal pancreatectomy (ODP). Records for patients undergoing DP between January 2006 and December 2009 were reviewed. Clavien-Dindo grade IIIb, IV, and V complications were classified as severe adverse--poor quality--postoperative outcomes (SAPOs). II and IIIa complications requiring either significantly prolonged overall lengths of stay including readmissions within 90 days or more than one invasive intervention were also classified as SAPOs. By Clavien-Dindo system alone, 91 % of DP patients had either no complication or a low/moderate grade (I, II, IIIa) complication. Using our reclassification, however, 25 % had a SAPO. Patients undergoing LDP demonstrated a Clavien-Dindo complication profile identical to that for SDP but demonstrated significantly shorter overall lengths of stay, were less likely to require perioperative transfusion, and less likely to have a SAPO. Established systems undergrade the severity of some complications following DP. Using a procedure-specific metric for quality, we demonstrate that LDP affords a higher quality postoperative outcome than ODP.

Laparoscopic Roux-en-Y gastric bypass (LRYGB) and laparoscopic vertical sleeve gastrectomy (LVSG), have been proposed as cost-effective strategies to manage obesity-related chronic disease. The objectives of this meta-analysis and systematic review were to analyze the "late postoperative complication rate (>30 days)" for these 2 procedures. Randomized controlled trials (RCTs) published between 2000 and 2015 comparing the late complication rates, that is, >30 days following LVSG and LRYGB in adult population (ie, 16 y and above) were selected from PubMed, Medline, Embase, Science Citation Index, Current Contents, and the Cochrane database. The outcome variables analyzed included mortality rate, major and minor complications, and interventions required for their management and readmission rates. Random effects model was used to calculate the effect size of both binary and continuous data. Heterogeneity among the outcome variables of these trials was determined by the Cochran Q statistic and I index. The meta-analysis was prepared in accordance with the Preferred Reporting of Systematic Reviews and Meta-Analyses guidelines. Six RCTs involving a total of 685 patients (LVSG, n=345; LRYGB, n=340) reported late major complications. A nonstatistical reduction in relative odds favoring the LVSG procedure was observed [odds ratio (OR), 0.64; 95% confidence interval (CI), 0.21-1.97; P=0.4]. Four RCTs representing 408 patients (LVSG, n=208; LRYGB, n=200) reported late minor complications. A nonstatistically significant reduction of 36% in relative odds favoring the LVSG procedure was observed (OR, 0.64; 95% CI, 0.28-1.47; P=0.3). A 37% relative reduction in odds was observed in favor of the LVSG for the need for additional interventions to manage late postoperative complications that did not reach statistical significance (OR, 0.63; 95% CI, 0.19-2.05; P=0.4). No study specifically reported readmissions required for the management of late complication. This meta-analysis and

To evaluate the long-term outcomes of pylorus-vagus-preserving partial gastrectomy for early gastric cancer in middle third of stomach. Between January 2004 and June 2009, 46 patients with early gastric cancer in middle third of stomach underwent pylorus-vagus-preserving partial gastrectomy (PPG) while another 85 patients had conventional distal gastrectomy (DG). Clinicopathologic data and follow-up results of two groups were analyzed retrospectively, including the results of subjective nutritional assessments, laboratory blood biochemical data, endoscopic findings of remnant stomach and total 5-year survival rates. Postprandial dumping syndrome occurred in 7 patients (8.2%) in DG group while no syndrome occurred in PPG group. The incidence of gallbladder stones at 18 months after operation in DG group was higher than that in PPG group. Significant difference existed between two groups (P<0.05). Even though no significant difference existed in laboratory blood biochemical data and endoscopic findings, PPG group recovered better and regurgitation was frequently found in DG group. Food residue in gastric remnant was frequently observed in PPG (31.1%) than in DG (10.8%, P<0.05) by endoscopic findings. At 2 years post-operation, the postoperative 5-year recurrence rate was 6.5% (2/46) in PPG group versus 8.2% (7/85) in DG group. However no significant difference existed between 2 groups (P=0.724). No significant difference existed between PPG group (91.3%) and DG group (90.6%) in overall 5-year survival rate. For early gastric cancer in middle third of stomach, pylorus-vagus-preserving partial gastrectomy is effective in maintaining postoperative function. And it has the same postoperative survival rate as conventional distal gastrectomy.

Transvaginal natural orifice translumenal endoscopic surgery (NOTES) gastrectomy is technically challenging, because wide perigastric dissection under appropriate tissue triangulation is unfeasible with current endoscopic instruments alone. The aim of this study was to investigate the feasibility of transvaginal NOTES gastrectomy with the use of an extra endoscope as a retracting device of the stomach. This acute in vivo feasibility study was performed under the approval of the Institutional Animal Care and Use Committee (IACUC). Four female 40-kg pigs received general anesthesia and underwent transvaginal endoscopic partial gastrectomy. Under laparoscopic guidance, the uterus was fixed anteriorly and transvaginal access was established in a standard fashion. The perigastric ligaments were dissected with needle knife/insulation-tipped electrosurgical knife (IT) via transvaginally placed double-channel endoscope. This step was assisted with the second, CO(2)-insufflating endoscope advanced in the stomach (i.e., so-called endoscopic gastric control). A linear stapling device with a flexible shaft was then passed transvaginally, and the anterior gastric wall was partially resected. The specimen was isolated and retrieved through the vagina. Concluding endoscopy was carried out to confirm the absence of mucosal damage due to endoscopic gastric control. This was further confirmed at necropsy immediately after sacrifice. All animals underwent successful transvaginal NOTES gastrectomy. Endoscopic gastric control greatly facilitated perigastric dissection by providing appropriate tissue countertraction on the ligaments. Use of transabdominal (laparoscopic) graspers was thus minimized. There were no intraoperative complications directly related to use of the primary (transvaginal) endoscope or the additional (gastric) endoscope. Distention of downstream bowel after gastric insufflation was minimal with CO(2). No major injuries were noted on gastric mucosa at postmortem

Background Laparoscopic surgery has been increasingly applied to gastric cancer surgery. Gastrointestinal tract reconstruction totally done by laparoscopy also has been a challenge for those who developed this procedure. Aim To describe simplified reconstruction after total or subtotal gastrectomy for gastric cancer by laparoscopy and the results of its application in a series of cases. Methods In the last four years, 75 patients were operated with gastric cancer and two with GIST. Thirty-four were women and 43 men. The age ranged from 38 to 77 years with an average of 55 years. In two patients with GIST a total and a subtotal gastrectomy were performed. In the other 75 patients were done 21 total gastrectomies and 54 subtotal. In all cancers, gastrectomy with D2 lymphadenectomy was completed with at least 37 lymph nodes removed. Was used in these operations a modified laparoscopic technique proposed by the authors consisting in a latero lateral esophagojejunal anastomosis with linear stapler in TG as well in STG, and reconstruction of the digestive continuity also in the upper abdomen. Results The intraoperative and immediate postoperative course were uneventful, except for one case of bleeding due to an opening clip, necessitating re-intervention. The operative time was 300 minutes, with no difference between total or subtotal gastrectomy. The number of lymph nodes removed varied from 28 to 69, averaging 37. Postoperative staging showed one case in T4 N2 M0; 13 in T2 N0 MO; 27 in T2 N1 M0; 24 in T3 N1 M0 and 10 in T3 N2 M0. Complication in only one case was observed on the 10th postoperative day with a small anastomotic leakage in esophagojejunal anastomose with spontaneous closure. Conclusion The patient's evolution with no complications, no mortality and just one small anastomotic leakage with no systemic repercussions is a strong indication of the liability and feasibility of this innovative technical method.

Obesity is considered a public health problem and has led to advancements in bariatric surgery. Laparoscopic sleeve gastrectomy (LSG) had become the most performed procedure worldwide; however, its consequences on nutritional status in the short and long term are of concern. A retrospective analysis of medical records and bariatric database of patients who underwent LSG from October 2008-September 2015 at Al-Amiri Hospital, Kuwait, was performed. Data regarding nutritional status along with demographic data were collected over a 5-year follow-up period. One thousand seven hundred ninety-three patients comprising of 74% females and 26% males were included. The greatest % total body weight loss (%TBWL) was at 18 months post-LSG (33%), corresponding to a % excess weight loss (%EWL) of 73.8%. With regard to nutritional status, vitamin B1 showed a significant drop at 3-5 years post-op in comparison to pre-op value, but stayed within the normal range throughout the study. Red blood cells count, hemoglobin, and hematocrit also showed a significant drop starting from 6 months post-op until the fifth year of follow-up. On the other hand, vitamins B6 and B12 showed a significant increase at 6 months post-op and decreased afterwards, but did not reach pre-op values. Vitamin D also showed a significant increase throughout the study period from deficient value at the pre-op time, but remained insufficient. Albumin, transferrin, folate, ferritin, iron, and vitamin B2 showed no significant changes at 5 years post-LSG compared to pre-op values. Little is known about the nutritional status and optimal nutritional care plan post-LSG, especially in the longer term. Nutritional deficiencies were prevalent prior and post-LSG. Some of the nutritional parameters improved and even reached the abnormal high level post-LSG. These observations highlight the importance of pre- and post-operative nutritional assessment and tailored supplementation to ensure optimal nutritional status.

Bariatric surgery is the only treatment option that achieves sustained weight loss in obese patients and that also has positive effects on obesity-related comorbidities. Laparoscopic sleeve gastrectomy (LSG) seems to achieve equal weight loss as laparoscopic Roux-en-Y gastric bypass (LRYGB), but there is still much debate about the quality of life (QOL) after LSG, mainly concerning the association with gastroesophageal reflux. Our hypothesis is that QOL after LSG is comparable with QOL after LRYGB. Between February 2013 and February 2014, 150 patients were randomized to undergo either LSG or LRYGB in our clinic. Differences in QOL were compared between groups by using multiple QOL questionnaires at follow-up moments preoperatively and 2 and 12 months after surgery. After 12 months of follow-up, 128 patients had returned the questionnaires. Most QOL questionnaires showed significant improvement in scores between the preoperative moment and after 12 months of follow-up. The Gastroesophageal Reflux Disease Questionnaire (GerdQ) score deteriorated in the LSG group after 2 months, but recovered again after 12 months. After 2 months of follow-up, the mean GerdQ score was 6.95 ± 2.14 in the LSG group versus 5.50 ± 1.49 in the LRYGB group (p < 0.001). After 1 year, the mean GerdQ score was 6.63 ± 2.26 in the LSG group and 5.60 ± 1.07 in the LRYGB group (p = 0.001). This randomized controlled trial shows that patients who underwent LSG have significantly higher GerdQ scores at both 2 and 12 months postoperatively than patients who underwent LRYGB, whereas overall QOL did not differ significantly.

Laparoscopic Roux-en-Y gastric bypass (LRYGB) and laparoscopic vertical sleeve gastrectomy (LVSG) have been proposed as cost-effective strategies to manage obesity-related chronic disease. The aim of this systematic review was to study the peer review literature regarding postoperative nondiabetic comorbid disease resolution or improvement reported from randomized controlled trials (RCTs) comparing LVSG and LRYGB procedures. RCTs comparing postoperative comorbid disease resolution such as hypertension, dyslipidemia, obstructive sleep apnea, joint and musculoskeletal conditions, gastroesophageal reflux disease, and menstrual irregularities following LVSG and LRYGB were included for analysis. The studies were selected from PubMed, Medline, EMBASE, Science Citation Index, Current Contents, and the Cochrane database and reported on at least one comorbidity resolution or improvement. The present work was undertaken according to the Preferred Reporting Items of Systematic Reviews and Meta-Analyses (PRISMA). The Jadad method for assessment of methodological quality was applied to the included studies. Six RCTs performed between 2005 and 2015 involving a total of 695 patients (LVSG n = 347, LRYGB n = 348) reported on the resolution or improvement of comorbid disease following LVSG and LRYGB procedures. Both bariatric procedures provide effective and almost comparable results in improving or resolving these comorbidities. This systematic review of RCTs suggests that both LVSG and LRYGB are effective in resolving or improving preoperative nondiabetic comorbid diseases in obese patients. While results are not conclusive at this time, LRYGB may provide superior results compared to LVSG in mediating the remission and/or improvement in some conditions such as dyslipidemia and arthritis.

The study was carried out on type 2 diabetic obese patients who underwent laparoscopic sleeve gastrectomy (LSG). Patients underwent regular glycemic controls throughout 3 years and all patients were defined cured from diabetes according to conventional criteria defined as normalization of fasting glucose levels and glycated hemoglobin in absence of antidiabetic therapy. After 3 years of follow-up, Continuous Glucose Monitoring (CGM) was performed in each patient to better clarify the remission of diabetes. In this study, we found that the diabetes resolution after LSG occurred in 40% of patients; in the other 60%, even if they showed a normal fasting glycemia and A1c, patients spent a lot of time in hyperglycemia. During the oral glucose tolerance test (OGTT), we found that 2 h postload glucose determinations revealed overt diabetes only in a small group of patients and might be insufficient to exclude the diagnosis of diabetes in the other patients who spent a lot of time in hyperglycemia, even if they showed a normal glycemia (<140 mg/dL) at 120 minutes OGTT. These interesting data could help clinicians to better individualize patients in which diabetes is not resolved and who could need more attention in order to prevent chronic complications of diabetes.

Robotic gastrectomy has become increasingly popular in the treatment of gastric cancer, especially in Asian countries. The use of indocyanine green fluorescence has been reported in lymphatic mapping for gastric cancer in laparoscopic gastrectomy; however, there have been few reports regarding the use of indocyanine green in robotic gastrectomy. From January 2011 to March 2016, a total of 79 patients underwent robotic gastrectomy for gastric cancer. Among them, intraoperative subserosal injection (n = 9) or preoperative submucosal injection (n = 5) of indocyanine green with near-infrared imaging was performed in 14 patients, and the other 65 patients underwent robotic gastrectomy without the use of indocyanine green. There was no significant difference in the operative time, total number of retrieved lymph nodes, operative blood loss, and postoperative hospital stay between the patients who underwent robotic gastrectomy with or without indocyanine green fluorescence. For each lymph node station, there was significantly more number of retrieved lymph nodes in the indocyanine green group than in the no-indocyanine green group at the greater curvature side of the low body (#4d) to the infrapyloric region (#6) of the stomach. Five of the 14 patients who received an indocyanine green injection for lymphatic mapping had lymph node metastasis, and metastatic lymph nodes were located in the lymph node stations as detected by indocyanine green fluorescence during surgery. Indocyanine green fluorescence with near-infrared imaging is feasible and is a promising method of lymphatic mapping in robotic gastrectomy for gastric cancer. In future studies, larger patient numbers and long-term follow-up are required.

Abstract Laparoscopic sleeve gastrectomy (LSG) is a therapeutic option in severely obese patients. The aim of this study was to evaluate the presence of Helicobacter pylori (HP) gastritis and non-Helicobacter gastritis in the gastrectomy specimens, and its association to other variables. One hundred six sleeve gastrectomy specimens were examined histopathologically for the presence of gastritis and its relation to other factors like ethnicity, glycemic control, and postoperative complications. Twelve patients had HP gastritis, 39 had non-HP gastritis, and 55 had normal mucosa. There was a statistical difference between the Arab and Jewish Israeli patients in our study. Twenty-eight of the Arab patients had HP gastritis and 48% had non-HP gastritis. In the Jewish population 6% had HP gastritis and 34% had non-HP gastritis. The preoperative glycemic control was worse in the gastritis group with a mean HbA1c of 8.344% while in the normal mucosa group the mean HbA1c was 6.55. After operation the glycemic control reverted to normal in most the diabetic patients. There were few postoperative complications however, they were not related to HP. There is a high incidence of gastritis in obese patients. The incidence of gastritis in the Arab population in our study was higher than that in the Jewish population. The glycemic control before surgery was worse in patients with gastritis than in the normal mucosa group. HP bares no risk for postoperative complications after LSG and does not affect weight loss. However a larger cohort of patients must be studied to arrive at conclusive results. PMID:28422853

Thermal injury and unexpected bleeding caused by ultrasonic scalpels can lead to fatal complications in laparoscopic gastrectomy (LG), such as postoperative pancreatic fistulas (POPF). In this study, we developed the "Hit and Away" protocol for optimal usage of the ultrasonic scalpel, which in essence involves dividing tissues and vessels in batches using the tip of the scalpel to control tissue temperature. To assess the effectiveness of the technique, the surface temperature of the mesocolon of female swine after ultrasonic scalpel activations was measured, and tissue samples were collected to evaluate microscopic thermal injury to the pancreas. In parallel, we retrospectively surveyed 216 patients who had undergone LG before or after the introduction of this technique and assessed the ability of this technique to reduce POPF. The tissue temperature of the swine mesocolon reached 43 °C, a temperature at which adipose tissue melted but fibrous tissue, including vessels, remained intact. The temperature returned to baseline within 3 s of turning off the ultrasonic scalpel, demonstrating the advantage of using ultrasonic scalpel in a pulsatile manner. Tissue samples from the pancreas demonstrated that the extent of thermal injury post-procedure was limited to the capsule of the pancreas. Moreover, with respect to the clinical outcomes before and after the introduction of this technique, POPF incidence decreased significantly from 7.8 to 1.0% (p = 0.021). The "Hit and Away" technique can reduce blood loss and thermal injury to the pancreas and help to ensure the safety of lymph node dissection in LG.

This was a retrospective analysis of the prospectively collected data of patients with morbid obesity who underwent LSG. Patients were subdivided into two groups: Group I, which did not receive prophylactic treatment with UCDA after LSG; and Group II, which received UCDA therapy for 6 months after LSG. Patients' characteristics, operation duration, weight loss data, and incidence of CL at 6 and 12 months postoperatively were collected. A total of 406 patients (124 males, 282 females) with a mean age of 32.1 ± 9.4 years were included. The mean baseline body mass index (BMI) was 50.1 ± 8.3 kg/m 2 . Group I comprised 159 patients, and Group II comprised 247 patients. The two groups showed comparable demographics, % excess weight loss (EWL), and decrease in BMI at 6 and 12 months after LSG. Eight patients (5%) developed CL in Group I, whereas no patients in Group II did (P = 0.0005). Preoperative dyslipidemia and rapid loss of excess weight within the first 3 months after LSG were the risk factors that significantly predicted CL postoperatively. The use of UCDA effectively reduced the incidence of CL after LSG in patients with morbid obesity. Dyslipidemia and rapid EWL in the first 3 months after LSG significantly predisposed patients to postoperative CL.

AIM: To describe the clinical characteristics, technical procedures, and outcomes of patients undergoing laparoscopic spleen-preserving distal pancreatectomy (LSPDP) for benign and malignant pancreatic neoplasms. METHODS: The clinical data of 38 patients who underwent LSPDP in the Sir Run Run Shaw Hospital between January 2003 and August 2013 were analyzed retrospectively. Surgical techniques for LSPDP included preservation of the splenic artery and vein (Kimura’s technique) and ligation of the splenic pedicle with preservation of the short gastric vessels (Warshaw’s technique). RESULTS: There were no conversions to open surgery in the 38 patients. Splenic vessels were conserved during spleen-preserving pancreatectomy, except in two patients who underwent resection of the splenic vessels and preservation only of the short gastric vessels. The mean operation time was 123.2 ± 52.4 min, the mean intraoperative blood loss was 78.2 ± 39.5 mL, and the mean postoperative hospital stay was 7.6 ± 2.9 d. The overall rate of postoperative complications was 18.4% (7/38), and the rate of clinical pancreatic fistula was 13.2% (5/38). All postoperative complications were treated conservatively. The postoperative pathological diagnoses were 22 cases of benign pancreatic disease and 16 cases of borderline or low-grade malignant lesions. During a median follow-up of 38 mo (range: 5-133 mo), no recurrence was observed. CONCLUSION: LSPDP is a safe, feasible and effective procedure for the treatment of benign and low-grade malignant tumors of the distal pancreas. PMID:25320534

In this paper, we describe operative technique details and our results with a modified technique for jejunal pouch formation and interposition after total gastrectomy, with an overall aim to achieve results superior to jejunal pouch and Roux-en-Y reconstruction, as reported in the literature. Following total gastrectomy, the jejunum was divided approximately 20 cm distal to the ligament of Treitz. Marginal vessels were not divided in order to preserve the nerves in the 50 cm of distal jejunum which would be used for pouch construction. The pouch was constructed using a linear stapler (Endo GiA, United States Surgical Corp., Norwalk, Conn). A total of 15 gastric cancer patients underwent construction of a nerve-preserving jejunal pouch and interposition following total gastrectomy. None of the patients experienced postoperative complications due to pouch construction. Additionally, discomforts such as dumping or stagnation were not observed. Mild reflux esophagitis occurred in five of the 15 patients and was resolved by oral administration of camostat mesilate. Six months after surgery, the average patient's diet volume and body weight had gradually increased to 79% and 86%, respectively, of the presurgical levels. A dual phase, dual isotope radionucleid pouch emptying study was also performed six months after surgery. The intra-pouch RI retention rate was 47% for liquid food and 53% for solid food 120 minutes after intake. The emptying rate was slower for both solid and liquid food, as compared with healthy individuals. The pouch-emptying test demonstrated a satisfactory retention capacity and an acceptable emptying time as a gastric substitute. The patients who underwent gastric reconstruction with a nerve-preserving jejunal pouch with interposition have experienced a reasonably good quality of life.

Staple-line leak is the most frightening complication of laparoscopic sleeve gastrectomy and several predisposing factors such as using improper staple sizes regardless of gastric wall thickness, narrower bougie diameter and ischemia of the staple line are asserted. To evaluate the effects of different bougie diameters on tissue oxygen partial pressure at the esophagogastric junction after sleeve gastrectomy. A randomized and controlled animal experiment with 1:1:1:1 allocation ratio. Thirty-two male Wistar Albino rats were randomly divided into 4 groups of 8 each. While 12-Fr bougies were used in groups 1 and 3, 8-Fr bougies were used in groups 2 and 4. Fibrin sealant application was also carried out around the gastrectomy line after sleeve gastrectomy in groups 3 and 4. Burst pressure of gastrectomy line, tissue oxygen partial pressure and hydroxyproline levels at the esophagogastric junction were measured and compared among groups. Mortality was detected in 2 out of 32 rats (6.25%) and one of them was in group 2 and the cause of this mortality was gastric leak. Gastric leak was detected in 2 out of 32 rats (6.25%). There was no significant difference in terms of burst pressures, tissue oxygen partial pressure and tissue hydroxyproline levels among the 4 groups. The use of narrower bougie along with fibrin sealant has not had a negative effect on tissue perfusion and wound healing.

Stomach traction done to expose the pancreas is still a problem in laparoscopic left pancreatic resections. We developed a simple hanging maneuver to retract the stomach rapidly and effectively. After dividing the gastrocolic ligament, the stomach was encircled with a tape, turned along its horizontal axis and pulled with an epigastric trocar, which was later removed. This technique was used in all patients who underwent laparoscopic left pancreatic resections including 165 distal pancreatectomies (DP), 35 central pancreatectomies (CP) and 18 enucleations (En). Demographics, surgical and postoperative outcome data were recorded. There were no mortalities. The mean operative time for DP, CP and En were 174, 191 and 104 min, respectively. The transfusion (0-4%) and conversion (0-3%) rates were low for all procedures. Morbidity was mainly represented by pancreatic fistula and grades (B + C) for DP, CP and En were observed in 26, 22 and 17%, respectively. No complication related to hanging of the stomach, like gastric perforation, was observed. Re-intervention and the mean hospital stay for DP, CP and En were observed in 5, 11 and 0% and were 16, 22 and 12, respectively. The readmission rate was low (0-9%). Hanging maneuver of the stomach is a simple procedure to rapidly, safely and effectively retract the stomach during left laparoscopic pancreatic resections. © 2016 S. Karger AG, Basel.

Laparoscopic pancreatectomy: Indications and outcomes

The application of minimally invasive approaches to pancreatic resection for benign and malignant diseases has been growing in the last two decades. Studies have demonstrated that laparoscopic distal pancreatectomy (LDP) is feasible and safe, and many of them show that compared to open distal pancreatectomy, LDP has decreased blood loss and length of hospital stay, and equivalent post-operative complication rates and short-term oncologic outcomes. LDP is becoming the procedure of choice for benign or small low-grade malignant lesions in the distal pancreas. Minimally invasive pancreaticoduodenectomy (MIPD) has not yet been widely adopted. There is no clear evidence in favor of MIPD over open pancreaticoduodenectomy in operative time, blood loss, length of stay or rate of complications. Robotic surgery has recently been applied to pancreatectomy, and many of the advantages of laparoscopy over open surgery have been observed in robotic surgery. Laparoscopic enucleation is considered safe for patients with small, benign or low-grade malignant lesions of the pancreas that is amenable to parenchyma-preserving procedure. As surgeons’ experience with advanced laparoscopic and robotic skills has been growing around the world, new innovations and breakthrough in minimally invasive pancreatic procedures will evolve.

Laparoscopic sleeve gastrectomy (LSG) is widely adopted but exposes serious complications. A retrospective database analysis was done to study LSG staple line complications in a tertiary referral university center with surgical ICU experienced in treatment of morbid obesity and complications. Twenty-two consecutive patients were referred between January 2004 and February 2012 with postoperative gastric leak or stenosis after LSG. Interventions consisted in the control of intra-abdominal and general sepsis; restoration of staple line continuity or revision of LSG; nutritional support; treatment of associated complications. Main outcome measures concerned success rates of therapeutic strategies, morbidity and mortality rates, LOS, and time to cure. Thirteen patients (59 %) were referred after failure of reoperation (seven fistula repairs were attempted). Three patients received emergency surgery in our center with transorificial intubation and jejunostomy formation. An endoscopic stent was tried in nine patients but failed in 84.6 % of cases within 20 days (1-161). Seven patients (32 %) necessitated total gastrectomy within 217 days (0-1,915 days) for conservative treatment failure. Procedures under general anesthesia were required in 41 % of cases, organ failure was found in 55 % of cases, and central venous device infection in 40 %. Mortality rate was 4.5 % (n = 1). Patients with unfavorable evolution of LSG complications (death or additional gastrectomy) had more previous bariatric procedure (82 % vs. 18 %, p = 0.003). Median time to cure was 310 days (9-546 days). LSG exposes severe complications occurring in patients with benign condition. Endoscopic stents entail high failure rate. Total gastrectomy is required in one third of the cases.

Bariatric surgery makes up an increasing percentage of general surgery training. The safety of resident involvement in these complex cases has been questioned. We evaluated patient outcomes in resident performed laparoscopic bariatric procedures. Retrospective review of patients undergoing a laparoscopic bariatric procedure over seven years at a tertiary care single center. Procedures were primarily performed by a general surgery resident and proctored by an attending surgeon. Primary outcomes included operative volume, operative time and leak rate with perioperative outcomes evaluated as secondary outcomes. A total of 1649 bariatric procedures were evaluated. Operations included laparoscopic bypass (690) and laparoscopic sleeve gastrectomy (959). Average operating time was 136 min. Eighteen leaks (0.67%) were identified. Graduating residents performed an average of 89 laparoscopic bariatric cases during their training. There were no significant differences between resident levels with concern to operative time or leak rate (p 0.97 and p = 0.54). General surgery residents can safely perform laparoscopic bariatric surgery. When proctored by a staff surgeon, a resident's level of training does not significantly impact leak rate.

Morbid obesity is a barrier to kidney transplantation due to inferior outcomes, including higher rates of new-onset diabetes after transplantation (NODAT), delayed graft function (DGF), and graft failure. Laparoscopic sleeve gastrectomy (LSG) increases transplant eligibility by reducing BMI in kidney transplant candidates, but the effect of surgical weight loss on posttransplantation outcomes is unknown. Reviewing single-center medical records, we identified all patients who underwent LSG before kidney transplantation from 2011-2016 (n = 20). Post-LSG kidney recipients were compared with similar-BMI recipients who did not undergo LSG, using 2:1 direct matching for patient factors. McNemar's test and signed-rank test were used to compare groups. Among post-LSG patients, mean BMI ± standard deviation (SD) was 41.5 ± 4.4 kg/m 2 at initial encounter, which decreased to 32.3 ± 2.9 kg/m 2 prior to transplantation (P < .01). No complications, readmissions, or mortality occurred following LSG. After transplantation, one patient (5%) experienced DGF, and no patients experienced NODAT. Allograft and patient survival at 1-year posttransplantation was 100%. Compared with non-LSG patients, post-LSG recipients had lower rates of DGF (5% vs 20%) and renal dysfunction-related readmissions (10% vs 27.5%) (P < .05 each). Perioperative complications, allograft survival, and patient survival were similar between groups. These data suggest that morbidly obese patients with end-stage renal disease who undergo LSG to improve transplant candidacy, achieve excellent posttransplantation outcomes. © 2017 The American Society of Transplantation and the American Society of Transplant Surgeons.

Reinforcement of the staple line in laparoscopic sleeve gastrectomy (LSG) is a practice that leads to less morbidity, but equivocal results have been reported in the literature. This is a prospective randomized study comparing two groups of patients who underwent LSG. In one group LSG was performed with a running absorbable suture placement at the staple line. In the other group the running suture was not placed. General data of the patients, as well as intraoperative and postoperative data, were gathered and statistically analyzed. Overall, 146 patients were subjected to LSG. In 84 patients a running suture was placed, and in 62 patients no suture was placed. No significant differences were found between the two groups in demographic data. No significant differences were found also in the intraoperative data, such as number of trocars, number and type of cartridges, drain placement, and operative time (45±21 versus 40±20 minutes, respectively; P<.05). Intraoperative complications were significantly more in the group with the suture placement (33.3% versus 16.1%, respectively; P<.05). Hematomas developed intraoperatively in more patients after the placement of the running suture (9.5% versus 0.0%, respectively; P<.05). Postoperatively, there was no significant difference in morbidity between the two groups (8.3% versus 9.7%, respectively; P>.05). After this randomized study, final conclusions about the efficacy of this running suture to the staple line cannot be made. To the contrary, problems seem to exist after such reinforcement of the staple line, such as hematomas. Dealing with possible leaks and hemorrhage of the staple line is also problematic after placement of the running suture.

Laparoscopic sleeve gastrectomy (SG) has become the most frequently performed bariatric procedure worldwide. De novo reflux might impact patients' quality of life, requiring lifelong proton pump inhibitor medication. It also increases the risk of esophagitis and formation of Barrett's metaplasia. Besides weight regain, gastroesophageal reflux disease (GERD) is the most common reason for conversion to Roux-en-Y gastric bypass. We performed 24-h pH metries, manometries, gastroscopies, and questionnaires focusing on reflux (GIQLI, RSI) in SG patients with a follow-up of more than 10 years who did not suffer from symptomatic reflux or hiatal hernia preoperatively. From a total of 53 patients, ten patients after adjustable gastric banding were excluded. From the remaining 43, six patients (14.0%) were converted to RYGB due to intractable reflux over a period of 130 months. Ten out of the remaining non-converted patients (n = 26) also suffered from symptomatic reflux. Gastroscopies revealed de novo hiatal hernias in 45% of the patients and Barrett's metaplasia in 15%. SG patients suffering from symptomatic reflux scored significantly higher in the RSI (p = 0.04) and significantly lower in the GIQLI (p = 0.02) questionnaire. This study shows a high incidence of Barrett's esophagus and hiatal hernias at more than 10 years after SG. Its results therefore suggest maintaining pre-existing large hiatal hernia, GERD, and Barrett's esophagus as relative contraindications to SG. The limitations of this study-its small sample size as well as the fact that it was based on early experience with SG-make drawing any general conclusions about this procedure difficult.

We describe a novel endoscopic approach and provide a literature review for the "en bloc" dissection of the distal ureter and bladder cuff during laparoscopic radical nephroureterectomy using a transvesical single port approach under pneumovesicum. The procedure was performed in an 80-year old male with a history of gross hematuria due to left renal pelvic TCC and no history of prior bladder TCC. Laparoscopic radical nephroureterectomy was performed and the ureter was dissected down to the bladder and clipped. A single-port device was inserted transvesically and pneumovesicum established. A full thickness incision of the bladder around the ureter was performed with progressive intravesical mobilization of the distal ureter. Subsequently, a water-tight closure of the bladder defect was achieved. The distal ureter, together with the bladder cuff, was then delivered en bloc laparoscopically with the specimen. The operating time (LESS radical nephroureterectomy, RPLND, and bladder cuff excision) was 6hours and 15minutes. The bladder cuff time was 45minutes. There were no intra or postoperative complications and the catheter was removed after 6 days. Histopathological analysis showed kidney-invasive papillary urothelial cancer, pT3 pN0 (0/7) G3. The distal ureter and bladder cuff techniques have not yet been standardized. Management of the bladder cuff with a single port is feasible. Additional studies are needed to identify the best approach for management of the distal ureter at the time of laparoscopic nephroureterectomy. Copyright © 2010 AEU. Published by Elsevier Espana.

The effectiveness of the concomitant repair of hiatal hernia (HHR) during laparoscopic sleeve gastrectomy (LSG) in reducing gastroesophageal reflux disease (GERD) symptoms is still unclear. The aim of this study is to assess the effect of concomitant HHR on postoperative GERD symptoms in our patient population. A retrospective review of patients who underwent LSG with or without HHR between 2011and 2014 was performed. Pre- and postoperative GERD symptoms were assessed at different time intervals until a maximum of 2 years after the surgery. The study included 165 patients; 76 (46%) underwent LSG with concomitant HHR (group A) while the rest underwent only LSG (group B). Baseline GERD complaints were more prevalent in group A (61.8 vs 41.6%, p = 0.04), in which 44 patients (57.9%) had evidence of hiatal hernia on preoperative EGD. In the remaining 32 patients, it was diagnosed intraoperatively. GERD symptoms did not significantly differ between the two groups after years 1 and 2. GERD remission was observed in 21.3% of the 76 patients who underwent concomitant HHR (group A) and in 29.7% of those who did not (group B) while new-onset GERD symptoms were reported in 12 patients (41.4%) in group A and in 24 patients (46.2%) in group B. Routine HHR at the time of LSG does not show an improvement in GERD symptoms. More prospective studies are needed to clarify the role of the routine dissection, identification, and repair of concomitant hiatal hernia during LSG.

Laparoscopic sleeve gastrectomy (LSG) is one of the most prefered treatment option for morbid obesity. However, the effects of LSG on gastroesophageal reflux disease (GERD) are controversial. Asymptomatic GERD and hiatal hernia (HH) is common in obese patients. Therefore, it is important to identify the high risk patients prior to surgery. This study aims to evaluate efficacy of cruroplasty for HH during LSG in morbidly obese patients using ambulatory pH monitoring (APM) results, and to investigate the patients' selection criteria for this procedure. This retrospective study includes outcomes of 59 patients who underwent LSG and HH repair according to our patient selection algorithm. Outcomes included preoperative GERD Health-Related Quality of Life (GERD-HRQL) questionnaire, APM results, percentage of postoperative excess weight loss, and total weight loss. For a total of 402 patients, APM was applied in 70 patients who had a positive score of GERD-HRQL, and 59 patients underwent LSG and concomitant HH repair who had a DeMeester score of 14.7% or above. There was no statistically significant difference in weight loss at 6 and 12-month follow-up. Two patients (3.3%) had symptoms of GERD at 12 months postoperatively, and only one (1.6%) patient required treatment of proton pump inhibitor for reflux. In the total cohort, 11 (2.7%) patients also evolved de novo GERD symptoms. This study confirm that careful attention to patient selection and surgical technique can reduce the symptoms of GERD at short-term. Routine bilateral crus exploration could be a major risk factor of postoperative GERD.

Adeno-carcinomas of pancreatic body are usually asymptomatic and progress to advanced stage with involvement of major arteries. Resection of advanced cancer along with en bloc resection of a common hepatic artery and celiac trunk enables a "curative" resections and only possible treatment. However, the celiac axis resection always has a risk of compromising blood supply to liver, resulting in the hepatic insufficiency. We evaluated practicability of a two-stage procedure for the advanced pancreases body cancer, laparoscopic clamping of a common hepatic artery followed by open distal pancreatectomy with en bloc celiac arterial resection to prevent the hepatic insufficiency. Seventy-five-year-old woman diagnosed with a 50-mm pancreatic body mass, invading splenic artery, common hepatic artery, splenic vein, and portal vein at the confluence. STAGE-1: At laparoscopy, after confirming absence of the peritoneal, superficial liver metastases and negative peritoneal cytology; we approached the common hepatic artery through the lesser sac and ligated. STAGE-2: Her liver function tests were normal after 2 weeks, and CT angiography showed complete blockage of the common hepatic artery with sufficient collateral circulation to the liver through inferior pancreatico-duodenal artery and gastro-duodenal artery. We performed an open distal pancreatectomy with en bloc resection of celiac artery. Histopathology examination confirmed R0 resection. The celiac axis resection with distal pancreatectomy improves the chance of R0 resection and potentially, survival of the patient. Preoperative laparoscopic ligation of the common hepatic artery is a safe, effective, and in-expensive technique to prevent postoperative hepatic insufficiency and improves the safety of en bloc celiac artery resection with a distal pancreatectomy. Also these patients have high risk of peritoneal dissemination. Diagnostic laparoscopy is useful to detect occult metastasis, which are missed by per-operative CT

Background The anatomical and physiological changes with Roux-en-Y gastric bypass (RYGB) may lead to uncommon but occasionally difficult to treat complications such as hyperinsulinemic hypoglycemia with neuroglycopenia and recalcitrant hypocalcemia associated to hypoparathyroidism. Medical management of these complications is challenging. Laparoscopic reversal of RYGB anatomy with restoration of pyloric function and duodenal continuity is a potential treatment. Objective To present the indications, surgical technique and clinical outcomes of laparoscopic reversal of RYGB. Setting Tertiary Academic Medical Center, United States. Methods Prospective study of consecutive patients offered laparoscopic reversal of RYGB. Results Five patients with remote laparoscopic RYGB underwent laparoscopic reversal of RYGB to normal anatomy (n=2) or modified sleeve gastrectomy (n=3). Indications were medically refractory hyperinsulinemic hypoglycemia with neuroglycopenia (n=3), recalcitrant hypocalcemia with hypoparathyroidism (n=1) and both conditions simultaneously (n=1). Prior to reversal all patients had a gastrostomy tube placed in the excluded stomach to document improvement of symptoms. Laparoscopic reversal was accomplished successfully in all patients. Three post-operative complications occurred; bleeding that required transfusion, gallstone pancreatitis and a superficial trocar site infection. Average length of stay was 3 days. At a mean follow-up of 12 months (range 3 to 22), no additional episodes of neuroglycopenia occurred, average number of hypoglycemic episodes per week decreased from 18.5±12.4 to 1.5±1.9 (p=0.05) and hypocalcemia became responsive to oral replacement therapy in both patients. Conclusions Laparoscopic reversal of RYGB to normal anatomy or modified sleeve gastrectomy is feasible and may be a therapeutic option for selected patients with medically refractory hyperinsulinemic hypoglycemia and/or recalcitrant hypocalcemia associated to

The aim of this study was to analyse the impact of hiatal hernia repair (HHR) on gastro-oesophageal reflux disease (GERD) in morbidly obese patients with hiatus hernia undergoing laparoscopic sleeve gastrectomy (LSG). It is a retrospective study involving ten morbidly obese patients with large hiatus hernia diagnosed on pre-operative endoscopy who underwent LSG and simultaneous HHR. The patients were assessed for symptoms of GERD using a Severity symptom score (SS) questionnaire and anti-reflux medications. Of the ten patients, five patients had GERD preoperatively. At the mean follow-up of 11.70 ± 6.07 months after surgery, four patients (80%) showed complete resolution while one patient complained of persistence of symptoms. Endoscopy in this patient revealed resolution of esophagitis indicating that the persistent symptoms were not attributable to reflux. The other five patients without GERD remained free of any symptom attributable to GERD. Thus, in all ten patients, repair of hiatal hernia (HH) during LSG led to either resolution of GERD or prevented any new onset symptom related to GER. In morbidly obese patients with HH with or without GERD undergoing LSG, repair of the hiatus hernia helps in amelioration of GERD and prevents any new onset GER. Thus, the presence of HH should not be considered as a contraindication for LSG.

The preoperative diagnosis of T stage is important in selecting limited treatments, such as laparoscopic proximal gastrectomy (LPG), which lacks the ability to palpate the tumor. Therefore, the present study examined the accuracy of preoperative diagnosis of the depth of tumor invasion in early gastric cancer from the view point of the indication for LPG. A total of 193 patients with cT1 gastric cancer underwent LPG with gastrointestinal endoscopic examinations and a series of upper gastrointestinal radiographs. The patients with pT1 were classified into the correctly diagnosed group (163 patients, 84.5%), and those with pT2 or deeper were classified into the underestimated group (30 patients, 15.5%). Factors that were associated with underestimation of tumor depth were analyzed. Tumor size in the underestimated group was significantly larger; the lesions were more frequently located in the upper third of the stomach and were more histologically diffuse, scirrhous, with infiltrative growth, and more frequent lymphatic and venous invasion. For upper third lesions, in univariate analysis, histology (diffuse type) was associated with underestimation of tumor depth. Multivariate analysis found that tumor size (≥20 mm) and histology (diffuse type) were independently associated with underestimation of tumor depth. gastric cancer in the upper third of the stomach with diffuse type histology and >20 mm needs particular attention when considering the application of LPG.

Tumor size in the underestimated group was significantly larger; the lesions were more frequently located in the upper third of the stomach and were more histologically diffuse, scirrhous, with infiltrative growth, and more frequent lymphatic and venous invasion. For upper third lesions, in univariate analysis, histology (diffuse type) was associated with underestimation of tumor depth. Multivariate analysis found that tumor size (≥20 mm) and histology (diffuse type) were independently associated with underestimation of tumor depth. gastric cancer in the upper third of the stomach with diffuse type histology and >20 mm needs particular attention when considering the application of LPG.

Bariatric procedures are technically complex and skill demanding. In order to standardize the procedures for research and training, a Delphi analysis was performed to reach consensus on the practice of the laparoscopic gastric bypass and sleeve gastrectomy in the Netherlands. After a pre-round identifying all possible steps from literature and expert opinion within our study group, questionnaires were send to 68 registered Dutch bariatric surgeons, with 73 steps for bypass surgery and 51 steps for sleeve gastrectomy. Statistical analysis was performed to identify steps with and without consensus. This process was repeated to reach consensus of all necessary steps. Thirty-eight participants (56%) responded in the first round and 32 participants (47%) in the second round. After the first Delphi round, 19 steps for gastric bypass (26%) and 14 for sleeve gastrectomy (27%) gained full consensus. After the second round, an additional amount of 10 and 12 sub-steps was confirmed as key steps, respectively. Thirteen steps in the gastric bypass and seven in the gastric sleeve were deemed advisable. Our expert panel showed a high level of consensus expressed in a Cronbach's alpha of 0.82 for the gastric bypass and 0.87 for the sleeve gastrectomy. The Delphi consensus defined 29 steps for gastric bypass and 26 for sleeve gastrectomy as being crucial for correct performance of these procedures to the standards of our expert panel. These results offer a clear framework for the technical execution of these procedures.

Background Although laparoscopic sleeve gastrectomy (LSG) has been shown to be a safe and effective treatment for severe obesity (body mass index ≥ 35), staple line leaks remain a major complication and account for a substantial portion of the procedure’s morbidity and mortality. Many centres performing LSG routinely obtain contrast studies on postoperative day 1 for early detection of staple line leaks. We examined the usefulness of Gastrografin swallow as an early detection test for staple line leaks on postoperative day 1 after LSG as well as the associated costs. Methods We conducted a retrospective review of a prospectively collected database that included 200 patients who underwent LSG for severe obesity between 2011 and 2014. Primary outcome measures were the incidence of staple line leaks and the results of Gastrografin swallow tests. We obtained imaging costs from appropriate hospital departments. Results Gastrografin swallow was obtained on postoperative day 1 for all 200 patients who underwent LSG. Three patients (1.5%) were found to have staple line leaks. Gastrograffin swallows yielded 1 true positive result and 2 false negatives. The false negatives were subsequently diagnosed on computed tomography (CT) scan. The sensitivity of Gastrografin swallow in this study was 33%. For 200 patients, the total direct cost of the Gastrografin swallows was $35 000. Conclusion The use of routine upper gastrointestinal contrast studies for early detection of staple line leaks has low sensitivity and is costly. We recommend selective use of CT instead.

Laparoscopic sleeve gastrectomy (LSG) has become an attractive bariatric procedure with promising treatment effects yet amount of data regarding institutional learning process is limited. Retrospective study included patients submitted to LSG at academic teaching hospital. Patients were divided into groups every 100 consecutive patients. LSG introduction was structured along with Enhanced Recovery after Surgery (ERAS) treatment protocol. Primary endpoint was determining the LSG learning curve's stabilization point, using operative time, intraoperative difficulties, intraoperative adverse events (IAE), and number of stapler firings. Secondary endpoints: influence on perioperative complications and reoperations. Five hundred patients were included (330 females, median age of 40 (33-49) years). Operative time in G1-G2 differed significantly from G3-G5. Stabilization point was the 200th procedure using operative time. Intraoperative difficulties of G1 differed significantly from G2-G5, with stabilization after the 100th procedure. IAE and number of stapler firings could not be used as predictor. Based on perioperative morbidity, the learning curve was stabilized at the 100th procedure. The morbidity rates in the groups were G1, 13%; G2, 4%; G3, 5%; G4, 5%; and G5, 2%. The reoperation rate in G1 was 3%; G2, 2%; G3, 2%; G4, 1%; and G5, 0%. The institutional learning process stabilization point for LSG in a newly established bariatric center is between the 100th and 200th operation. Initially, the morbidity rate is high, which should concern surgeons who are willing to perform bariatric surgery.

The effect of laparoscopic sleeve gastrectomy (SG) on gastroesophageal reflux disease (GERD) has been a controversial issue. There have been limited studies on this aspect and most of the published studies are retrospective. Therefore, a prospective study was designed to objectively assess the problem. The objective of this study was to assess the impact of SG on symptoms of gastroesophageal reflux using questionnaire, endoscopy, and radionuclide scintigraphy. Thirty-two patients undergoing laparoscopic sleeve gastrectomy were assessed for gastroesophageal reflux using Carlsson Dent Questionnaire and GERD questionnaire before and after surgery at three monthly intervals. They were also subjected to upper GI endoscopy (UGIE) and radionuclide scintigraphy both pre- and postoperatively. Mean preoperative weight and body mass index were 126.5 kg and 47.8 kg/m2, respectively. Mean percent excess weight loss at 12 months was 64.3 ± 18.4. Both the Carlsson Dent Score (CDS) and Severity Score (SS) exhibited a decline from 2.88 to 1.63 (p<0.05) and 2.28 to 1.06 (p<0.05), respectively after 12 months. Radionuclide scintigraphy revealed a significant rise of GERD from 6.25% to 78.1% in the postoperative period (p<0.001). UGIE showed a rise in incidence of esophagitis from 18.8% to 25%; however, there was improvement in all patients except one in terms of reduction of severity of esophagitis. Presence of GERD may not be considered as a contra-indication for sleeve gastrectomy. There is improvement of GERD as assessed by symptom questionnaires, as well as improvement in grade of esophagitis. The new onset GERD detected on scintigraphy may not be pathologic as there is a decrease in total acid production postsurgery; however, it still remains an important issue and needs long-term follow-up.

Portal vein thrombosis (PVT) is a serious problem with a high morbidity and mortality, often exceeding 40% of affected patients. Recently, PVT has been reported in patients after laparoscopic sleeve gastrectomy (LSG). The frequency is surprisingly high compared with other abdominal operations. We present a series of 5 patients with PVT after LSG. The treatment was not restricted simply to anticoagulation alone, but was determined by the extent of disease. A distinction is made among nonocclusive, high-grade nonocclusive, and occlusive PVT. We present evidence that systemic anticoagulation is insufficient in occlusive thrombosis and may also be insufficient in high-grade nonocclusive disease. Single private institution, United States. We present a retrospective analysis of 646 patients who underwent LSG between 2012 and 2015. In all patients, the diagnosis was established with an abdominal computed tomography (CT) scan as well as duplex ultrasound of the portal venous system. All patients received systemic anticoagulation. Depending on the extent of disease, thrombolytic therapy and portal vein thrombectomy were utilized. All patients received long-term anticoagulation. Four patients with PVT were identified. A fifth patient with PVT after LSG was referred from another center. The mean age of all patients was 49 years. One patient had a history of deep vein thrombosis (DVT). No complications were identified intraoperatively or during the hospital stay, and all patients were discharged by postoperative day 2. The patients presented with PVT at an average of 20 days (range: 10-35) post-LSG. The CT scan was positive for PVT in all patients. In stable noncirrhotic patients with nonocclusive disease, we administered therapeutic anticoagulation. One patient with high-grade, nonocclusive PVT received anticoagulation alone. Patients with occlusive disease were treated with operative thrombectomy including intraoperative and postoperative thrombolysis (tissue plasminogen

Objective Sleeve gastrectomy is the fastest growing surgical procedure to treat obesity in the world but it may cause or worsen gastroesophageal reflux disease. This article originally aimed to describe the addition of anti-reflux procedures (removal of periesophageal fats pads, hiatoplasty, a small plication and fixation of the gastric remnant in position) to the usual sleeve gastrectomy and to report early and late results. Methods Eighty-eight obese patients that also presented symptoms of gastroesophageal reflux disease were submitted to sleeve gastrectomy with anti-reflux procedures. Fifty of them were also submitted to a transit bipartition. The weight loss of these patients was compared to consecutive 360 patients previously submitted to the usual sleeve gastrectomy and to 1,140 submitted to sleeve gastrectomy + transit bipartition. Gastroesophageal reflux disease symptoms were specifically inquired in all anti-reflux sleeve gastrectomy patients and compared to the results of the same questionnaire applied to 50 sleeve gastrectomy patients and 60 sleeve gastrectomy + transit bipartition patients that also presented preoperative symptoms of gastroesophageal reflux disease. Results In terms of weight loss, excess of body mass index loss percentage after anti-reflux sleeve gastrectomy is not inferior to the usual sleeve gastrectomy and anti-reflux sleeve gastrectomy + transit bipartition is not inferior to sleeve gastrectomy + transit bipartition. Anti-reflux sleeve gastrectomy did not add morbidity but significantly diminished gastroesophageal reflux disease symptoms and the use of proton pump inhibitors to treat this condition. Conclusion The addition of anti-reflux procedures, such as hiatoplasty and cardioplication, to the usual sleeve gastrectomy did not add morbidity neither worsened the weight loss but significantly reduced the occurrence of gastroesophageal reflux disease symptoms as well as the use of proton pump inhibitors.

Abstract Laparoscopy-assisted distal gastrectomy (LADG) is widely used for gastric cancer (GC) patients nowadays. This study aimed to investigate the time trend of outcomes so as to describe the learning curve for GC patients with LADG at a single medical institution in western China over a 6-year period. A total of 246 consecutive GC patients with LADG were divided into 5 groups (group A: 46 patients from 2006 to 2007; group B: 47 patients in 2008; group C: 49 patients in 2009; group D: 73 patients in 2010; and group E: 31 patients in 2011). All surgeries were conducted by the same surgeon. Comparative analyses were successively performed by Mann–Whitney U test or Student t test among the 5 different groups for the clinical data, including clinicopathologic characteristics, surgical parameters, postoperative course, and survival outcomes, through which the learning curve was described. There were no differences in the baseline information among the 5 groups (P > 0.05), and the proportion of advanced GC patients with LADG slightly increased from 58.7% to 77.4% during the 6 years. Besides, the proportion of D2/D2+ lymphadenectomy and the number of retrieved lymph nodes gradually grew from 60.9% to 80.6% and from 20.0 to 28.8, respectively. In addition, the operation time decreased from 299.2 to 267.8 minutes, while the estimated blood loss dropped from 175.2 to 146.8 mL. Furthermore, some surgical parameters (surgical duration and blood loss) and postoperative course (such as postoperative complications, the time to ambulation, to first flatus, and to first liquid intake as well as the length of hospital stay) were all observed to be significantly different between group A and other groups (P < 0.05), illustrating a similar downward trend and remaining stable to form a plateau after 46 cases in group A. However, no difference on overall survival was found among these 5 groups, and multivariate analysis indicated that factors, such as age, tumor

Esophagojejunal fistula is a serious complication after total gastrectomy in gastric cancer patients. This study describes the successful conservative management in 3 gastric cancer patients with esophagojejunal fistula after total gastrectomy using total enteral nutrition. Between January 2004 to December 2008, 588 consecutive patients with a proven diagnosis of gastric cancer were taken to the operation room to try a curative treatment. Of these, 173 underwent total gastrectomy, 9 of them had esophagojejunal fistula (5.2%). In three selected patients a trans-anastomotic naso-enteral feeding tube was placed under fluoroscopic vision when the fistula was clinically detected and a complete polymeric enteral formula was used. The complete closing of the esophagojejunal fistula was obtained in day 8, 14 and 25 respectively. In some selected cases it is possible to make a successful enteral nutrition using a feeding tube distal to the leak area inserted with the help of fluoroscopic vision. The specialized management of a gastric surgery unit and nutritional therapy unit are highlighted.

Acanthosis nigricans (AN) has a close relationship with obesity. It is believed that obesity and AN have the common pathophysiological basis such as hyperinsulinism. This study is aimed to observe the effect of laparoscopic sleeve gastrectomy (LSG) on body composition and insulin resistance in Chinese obese patients with acanthosis nigricans. A total of 37 obese patients who underwent LSG in our hospital were selected for analysis. They were divided into simple obesity (OB n = 14) and obesity with acanthosis nigricans (AN n = 23) group respectively. Body composition was measured by dual-energy X-ray absorptiometry (DEXA). Anthropometric measurements and glucolipid metabolism before and 3 months post LSG were collected for analysis. Patients with AN got noticeable improvement in skin condition and their AN score was significantly decreased (3.52 ± 0.79 vs. 1.48 ± 0.73, P < 0.001).Alleviated insulin resistance and more trunk fat loss than limbs' were observed in both groups (P value < 0.01). In AN group, preoperative android fat mass (FM) was positively correlated with fasting insulin and natural logarithm of HOMA-IR (LNIR) (r = 0.622, 0.608, respectively; all P < 0.01). Besides, changes in android FM and visceral adipose tissue (VAT) also showed significantly positive correlation with changes in LNIR (r = 0.588, r = 0.598, respectively; all P < 0.01). LSG had a positive impact on body composition and skin condition in Chinese obese patients with AN. Loss of android FM and VAT might result in the alleviation of insulin resistance in AN patients. Android fat distribution seems to be a potential indicator of postoperative metabolic benefits for obese patients with AN.

Laparoscopic sleeve gastrectomy (LSG) has become a popular one-stage bariatric procedure with a proven efficacy on weight loss. However, the relationship between LSG and gastroesophageal reflux disease (GERD) remains a subject of debate. The objective is to determine the long-term effect of LSG on weight loss and reflux disease. A retrospective analysis of 100 consecutive patients who underwent an LSG between January 2005 and March 2009 was performed. The effect of LSG on weight evolution and the relationship between preoperative and postoperative GERD symptoms and PPI dependency was analyzed. A mean follow-up of 8.48 years (range 6.1-10.3) was achieved. We observed a long-term % excess weight loss (%EWL) of 60%. A significant increase in reflux symptoms and use of PPIs was seen. Seventeen percent suffered from reflux disease preoperatively versus 50% at the end of the postoperative follow-up (RR = 2.5882, 95% CI [1.6161-4.1452], p value = 0.0001). The chance of developing de novo reflux after LSG was 47.8% (32/67). Reflux disease was present in 7 of the 26 patients who underwent a secondary Roux-en-Y gastric bypass (RYGB). In four of these seven patients, reflux disease disappeared completely after the secondary RYGB (57.1%). A satisfactory long-term effect on weight loss was achieved. However, a significant increase in GERD and PPI dependency after LSG was noted. New onset GERD was seen in more than 40% of the study population. Conversion to RYGB is a good option in patients with refractory reflux disease after LSG.

The South Pacific has a high prevalence of obesity and super-obesity. We reviewed our experience with laparoscopic sleeve gastrectomy (LSG) to evaluate its efficacy and safety. A retrospective review of a prospectively collected database of LSGs carried out by one surgeon in one center. The percentage of excess weight loss and the rate of resolution or improvement of comorbidities reflected efficacy, and major complications or mortalities reflected safety. From January 2008 to February 2013, we performed 510 surgeries and included 494 consecutive patients (367 females) (45.5 ± 11.2 years) in our study. LSG was the primary procedure in 384 patients, 6 patients had redo bariatric surgery after failure of initial LSG, 57 patients had a history of gastric banding with insufficient weight loss or band-related complications, and 46 super-obese patients had an intragastric balloon placed before LSG. Average starting body mass index was 47.8 kg m(-2). Mean percent excess weight loss was 64.3% at 1 year; 67.3% at 2 years and 66.4% at 3 years. The percentages of resolved comorbidities were as follows: hypertension: 48.3%, type 2 diabetes mellitus: 72.5%, dyslipidemia: 61.0%, and obstructive sleep apnea: 77.8%. The mortality rate was 1/494. The postoperative morbidity included gastric fistula in 3.0%, hemorrhaging in 2.4%, and postoperative gastroesophageal reflux in 9.4%. In the South Pacific, LSG is a safe and effective means of treating morbid obesity with sustained weight loss and resolution of comorbid medical conditions. Copyright © 2016 IJS Publishing Group Ltd.

Obesity is frequently encountered in patients with orthotopic liver transplant (OLT). The role of bariatric surgery is still unclear for this specific population. The aim of this study was to review our experience with laparoscopic sleeve gastrectomy (LSG) after OLT. We performed a retrospective case-control study of patients undergoing LSG after OLT from 2010 to 2016. OLT-LSG patients were matched by age, sex, body mass index (BMI), and year to non-OLT patients undergoing LSG. Demographics, operative variables, postoperative events, and long-term weight loss with comorbidity resolution were collected and compared between cases and controls. Of 303 patients undergoing LSG, 12 (4%) had previous OLT. They were matched to 36 non-OLT patients. No difference was found between groups in the American Society of Anesthesiologists class, mean operative time, or postoperative morbidity. The non-OLT group, however, had a significantly shorter mean hospital stay than the OLT group (1.7 vs 3.1 days; P < .001). There were no conversions to open procedures. For patients with long-term follow-up, change in BMI after LSG was similar between the groups, but the non-OLT patients had significantly more excess body weight loss at 2 years (53.7 vs 45.2%; P < .001). Similar resolution of comorbid conditions was noted in both groups. LSG caused no changes in dosage of immunosuppressive medications, and no liver complications occurred. LSG after OLT in appropriately selected patients appears to have similar outcomes to LSG in non-OLT patients.

Introduction Increasing incidence of obesity in Indian population has led to an exponential rise in the number of bariatric operations performed annually. Laparoscopic Sleeve Gastrectomy (LSG) has been proposed to cause rapid remission of Type 2 Diabetes Melitus (T2DM) and metabolic syndrome in a weight loss independent manner. Aim To evaluate the effects of LSG on metabolic syndrome and central obesity in morbidly and severely obese Indian adults. Material and Methods: Study was conducted on 91 morbidly obese [Body Mass Index (BMI)>40 kg/m2] and severely obese (BMI>35 kg/m2) individuals who were suffering from diabetes, hypertension or dyslipidemia. The patients were followed up for six months and the trends of glycaemic control, mean blood pressure, lipid profile, weight loss parameters and changes in parameters of central obesity were studied. Results Weight loss was significant at three months postsurgery and was sustained through six months. There was significant improvement in glycaemic control leading to reduction in need for oral hypoglycaemic agents or insulin in majority of them and even discontinuation of these medications in few patients. Hypertension and dyslipidemia also showed an improving trend through six months postsurgery. There was a significant impact on reduction of central obesity in these patients as marked by significant reduction in waist to hip ratio. Conclusion LSG produces sustainable weight loss with significant improvement in glycaemic status and control of metabolic syndrome in severe to morbidly obese patients. LSG is also efficacious in reducing central obesity in Indian population which is a major depressive ailment amongst obese individuals. PMID:28273998

The purpose of this paper was to search for predictive factors for proximal leakage after laparoscopic sleeve gastrectomy (LSG) in a large cohort from a single referral center. One thousand seven hundred and thirty-eight patients, collected in a prospectively held database from 2008 to 2016, were retrospectively analyzed. The correlation between postoperative leakage and both preoperative (age, gender, height, weight, BMI, and obesity-related morbidities) and operative variables (the distance from pylorus at which the gastric section was started, operative time, experience of surgeons who performed the LSG, and the surgical materials used) was analyzed. The experience of the surgeons was calculated in the number of LSGs performed. The surgical materials considered were stapler, cartridges, and reinforcement of the suture. Proximal leakage was observed in 45 patients out of 1738 (2.6%). No correlation was found between leakage and the preoperative variables analyzed. The operative variables that were found to be associated with lower incidence of leakage at the multivariate analysis (p < 0.05) were the reinforcement of the staple line (or overriding suture or buttressing materials) and the experience of the surgeons. A distance of less than 2 cm from the pylorus resulted to be significantly related to a higher incidence of fistula at the univariate analysis. In this large consecutive cohort study of LSG, proximal staple line reinforcement (buttress material or suture) reduced the risk of a leak. The risk of a proximal leak was much higher in the surgeons first 100 cases, which has implications for training and supervision during this "learning curve" period.

Laparoscopic sleeve gastrectomy (LSG) is gaining popularity in treating morbid obesity. Prior studies showed a 3.5% risk of gastric sleeve stenosis (GSS). There is no consensus on how to treat these patients, and the role of endoscopic therapy has been addressed in only a few studies. We aim to assess the efficacy and safety of endoscopic stenting in the management of GSS following LSG. Retrospective data were reviewed from July 2009 to November 2013. Patients were referred for endoscopic therapy for symptoms or imaging findings suggestive of gastric leak or narrowing following LSG. Endoscopic therapy included the use of fully covered self-expanding esophageal metal stents (FCSEMS) in addition to over-the-scope clip system (OTSC) when necessary. All 27 patients were females with mean age of 40 years; six patients were excluded from the study. Major symptom was nausea and vomiting in 57% of the patients. Five of 21 patients had concomitant leaks. All 21 patients underwent FCSEMS placement, and four out of five patients (80%) with concomitant leak had OTSC. The success rate in both groups for resolution of stricture and leak was 100%, and no surgical intervention was required. There were no immediate or delayed complications of endoscopic therapy. Median follow-up of 6 months was available for 20/21 patients. Among patients with gastric leak, 80% had resolution of their symptoms compared with 93% of patients with GSS. Endoscopic therapy for LSG-related GSS or leaks with FCSEMS is highly effective and safe.

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

To compare the impact of laparoscopic Roux-en-Y gastric bypass (LRYGB) and laparoscopic sleeve gastrectomy (LSG) on weight loss and obesity related comorbidities over two year follow-up via case control study design. Forty patients undergoing LRYGB, who completed their two year follow-up were matched with 40 patients undergoing LSG for age, gender, body mass index and presence of type 2 diabetes mellitus (T2DM). Data of these patients was retrospectively reviewed to compare the outcome in terms of weight loss and improvement in comorbidities, i.e ., T2DM, hypertension (HTN), obstructive sleep apnea syndrome (OSAS), hypothyroidism and gastroesophageal reflux disease (GERD). Percentage excess weight loss (EWL%) was similar in LRYGB and LSG groups at one year follow-up (70.5% vs 66.5%, P = 0.36) while it was significantly greater for LRYGB group after two years as compared to LSG group (76.5% vs 67.9%, P = 0.04). The complication rate after LRYGB and LSG was similar (10% vs 7.5%, P = 0.99). The median duration of T2DM and mean number of oral hypoglycemic agents were higher in LRYGB group than LSG group (7 years vs 5 years and 2.2 vs 1.8 respectively, P < 0.05). Both LRYGB and LSG had significant but similar improvement in T2DM, HTN, OSAS and hypothyroidism. However, GERD resolved in all patients undergoing LRYGB while it resolved in only 50% cases with LSG. Eight point three percent patients developed new-onset GERD after LSG. LRYGB has better outcomes in terms of weight loss two years after surgery as compared to LSG. The impact of LRYGB and LSG on T2DM, HTN, OSAS and hypothyroidism is similar. However, LRYGB has significant resolution of GERD as compared to LSG.

AIM: To evaluate the safety and feasibility of laparoscopic spleen-preserving distal pancreatectomy (LSPDP) with autologous islet transplantation (AIT) for benign tumors of the pancreatic body-neck. METHODS: Three non-diabetic, female patients (age 37, 44 and 35 years, respectively) were declared candidates for surgery, between May and September 2011, because of pancreatic body/neck cystic lesions. The planned operation was an LSPDP associated with AIT from the normal pancreas distal to the neoplasm. Islets isolation was performed on the residual pancreatic parenchyma after frozen section examination of the margin. Purified autologous islets were infused into the portal vein by a percutaneous transhepatic approach the day after surgery. RESULTS: The procedure was performed successfully in all the three cases, and the spleen was preserved along with its vessels. Mean operation time was 283 ± 52 min and average blood loss was 133 ± 57 mL. Residual pancreas weights were 33, 22 and 30 g, and 105.200, 40.390 and 94.790 islet equivalents were isolated, respectively. Surgical complications occurred in one patient (grade A pancreatic fistula). Postoperative stays were 6, 6 and 7 d, respectively. Histopathological evaluation revealed mucinous cystic neoplasm in cases 1 and 3, and serous cystic neoplasm in patient 2. No postoperative insulin administration was required. One patient developed a transient partial portal thrombosis 2 mo after islet infusion. Patients are insulin independent at a mean follow up of 8 ± 2 mo. CONCLUSION: Combination of LSPDP and AIT is feasible and could be effective to minimize the surgical impact for benign neoplasm of pancreatic body-neck. PMID:24744593

To perform technically the laparoscopic sleeve gastrectomy (LSG) using a unique Intragastric Single Port (IGSG) in animal swine model, evidencing an effective and safe procedure, optimizing the conventional technique. IGSG was performed in 4 minipigs, using a percutaneous intragastric single port located in the pre-pyloric region. The gastric stapling of the greater curvature started from the pre-pyloric region towards the angle of His by Endo GIA™ system and the specimen was removed through the single port. In the postoperative day 30, the animals were sacrificed and submitted to autopsy. All procedures were performed without conversion, and all survived 30 days. The mean operative time was 42 min. During the perioperative period no complications were observed during invagination and stapling. No postoperative complications occurred. Post-mortem examination showed no leaks or infectious complications. Intragastric Single Port is a feasible procedure that may be a suitable alternative technique of sleeve gastrectomy for the treatment of morbid obesity.

To evaluate the ignition and burn risk associated with contemporary fiberoptic and distal sensor endoscopic technologies. We used new and used SCB Xenon 300 light sources to illuminate a 4.8 mm fiberoptic cable, 10 mm laparoscope, 5 mm laparoscope, rigid cystoscope, semirigid ureteroscope, flexible cystoscope, flexible fiberoptic ureteroscope, distal sensor cystoscope, and a distal sensor ureteroscope (Karl Storz, Inc., Tuttlingen, Germany). We measured peak temperatures at the distal end of each device. We then evaluated each device on a flat and folded surgical drape to establish ignition risk. Finally, we evaluated the effects of all devices on human cadaver skin covered by surgical drape. Peak temperatures recorded for each device ranged from 26.9°C (flexible fiberoptic ureteroscope) to 194.5°C (fiberoptic cable). Drape ignition was noted when the fiberoptic cable was placed against a fold of drape. Contact with the fiberoptic cable, 10 mm laparoscope, 5 mm laparoscope, and distal sensor cystoscope resulted in cadaver skin damage. Cadaver skin damage occurred despite little or no visible change to the surgical drape. Rigid and flexible fiberoptic cystoscopes and flexible fiberoptic ureteroscopes had no effect on surgical drapes or cadaver skin. Fiberoptic light cables and some endoscopic devices have the potential to cause thermal injury and drape ignition. Thermal injury may occur without visible damage to drapes. Surgeons should remain vigilant regarding the risks associated with these devices and take necessary safety precautions to prevent patient injury.

The European guidelines for bariatric surgery clearly define criteria for operating children with morbid obesity. However the appropriate technique for this age-group has not been identified yet. So far gastric banding and Roux-Y bypass represent the standards, but they demand life-long tolerance of either an artificial device or significant malabsorption. Although laparoscopic sleeve gastrectomy (LSG) demands neither, it has not been advocated for this age-group as a stand-alone technique. We report the outcome and the rationale for this approach in a 16-year-old girl with morbid obesity. The patient had been in an intensive weight loss programme for several years, but within the last 12 months her body weight had increased again dramatically. At referral she presented with a body mass index (BMI) of 43.1 kg/m(2) (height 169 cm, preoperative weight 121 kg) and suffered from co-morbidities as features of a developing metabolic-vascular syndrome such as dyslipidemia and arterial hypertension. Our obesity team and her parents opted for surgery at that time. The patient underwent LSG with a 5-trocar technique. With a gastroscope protecting the lesser curvature, the stomach was resected from the antrum to the fundus using an EndoGIA stapler. The operative time was 95 minutes, there were no perioperative complications and the patient was extubated immediately. An upper GI contrast study on postoperative day 4 showed a tubular gastric remnant with a volume of about 200 ml. The patient's diet was advanced as tolerated to full oral intake, and she was followed-up regularly in our special obesity outpatient clinic. After 12 months she had lost 36 kg (BMI 29 kg/m(2)) and enjoyed sports and activities with friends again. Laboratory studies ruled out malnutrition or vitamin deficiency. LSG is a safe and effective option for bariatric surgery in obese adolescents. It can be offered as a stand-alone restrictive operation and could be extended to a malabsorptive procedure at any

Laparoscopic sleeve gastrectomy (LSG) is becoming a primary bariatric surgery for obesity and related diseases. This study presents the outcome of LSG with regard to the remission of type 2 diabetes mellitus (T2 DM) and the usefulness of a grading system to categorize and predict outcome of T2 DM remission. A total of 157 patients with T2 DM (82 women and 75 men) with morbid obesity (mean body mass index 39.0±7.4 kg/m(2)) who underwent LSG from 2006 to 2013 were selected for the present study. The ABCD score is composed of the patient's age, body mass index, C-peptide level, and duration of T2 DM (yr). The remission of T2 DM after LSG was evaluated using the ABCD score. At 12 months after surgery, 85 of the patients had complete follow-up data. The weight loss was 26.5% and the mean HbA1c decreased from 8.1% to 6.1%. A significant number of patients had improvement in their glycemic control, including 45 (52.9%) patients who had complete remission (HbA1c<6.0%), another 18 (21.2%) who had partial remission (HbA1c<6.5%), and 9 (10.6%) who improved (HbA1c<7%). Patients who had T2 DM remission after surgery had a higher ABCD score than those who did not (7.3±1.7 versus 5.2±2.1, P<.05). Patients with a higher ABCD score were also at a higher rate of success in T2 DM remission (from 0% in score 0 to 100% in score 10). LSG is an effective and well-tolerated procedure for achieving weight loss and T2 DM remission. The ABCD score, a simple multidimensional grading system, can predict the success of T2 DM treatment by LSG. Copyright © 2015 American Society for Bariatric Surgery. Published by Elsevier Inc.

2015-12-01

Because vagally mediated reflex bradycardia occurs frequently during gastrectomy and is potentially harmful, we compared the incidence of clinically significant reflex bradycardia between patients undergoing laparoscopic gastrectomy (LG) and open gastrectomy (OG) and examined whether the type of surgery (OG vs. LG) was an independent risk factor for clinically significant reflex bradycardia. This prospective observational study evaluated 358 adult patients (age 18-70 years) who were undergoing elective OG or LG for gastric cancer resection. Symptomatic reflex bradycardia was defined as a sudden decrease in heart rate to <50 beats per minute (bpm), or to 50-59 bpm with a systolic blood pressure <70 mmHg, associated with a specific surgical maneuver. If bradycardia or hypotension developed, atropine or ephedrine was administered, in accordance with a predefined treatment protocol. The overall incidence of symptomatic reflex bradycardia was 24.6% (88/358). Univariate analysis revealed the incidence of symptomatic reflex bradycardia in the LG group was significantly lower than that in the OG group [13.0% (13/100) vs. 29.1% (75/258), p = 0.002]. Multivariate logistic regression analysis revealed that the type of surgery (OG vs. LG), advanced age, preoperative bradycardia, type of muscle relaxant (vecuronium vs. rocuronium), no use of intravenous remifentanil, and low core temperature, were independent risk factors for symptomatic reflex bradycardia (odds ratio 3.184; 95% confidence interval 1.490-6.800; p = 0.003). The LG approach was associated with a reduced risk of clinically significant reflex bradycardia compared with the OG approach.

The aim of this systematic review and meta-analysis is to evaluate the safety and relative benefits of delta-shape anastomosis (DA) by comparing to conventional laparoscopy-assisted distal gastrectomy with Billroth I gastroduodenostomy (LADG BI). Studies and relevant literature regarding DA versus LADG BI were searched in the electronic databases. Operation time, postoperative complications, estimated blood loss, number of retrieved lymph nodes, time to first flatus, time to oral intake, length of postoperative hospitalization in DA and LADG BI were pooled and compared using meta-analysis. Weighted mean differences (WMDs) and odds ratios (ORs) were calculated with 95% confidence intervals (CIs) to evaluate the effect of DA. Eight studies of 1739 patients were included in the meta-analysis. Compared with LADG BI, DA had shorter postoperative hospitalization (WMD = -0.47, 95%CI: -0.69 to -0.25, P<0.01), less blood loss (WMD = - 25.90, 95%CI: -43.11 to -8.70, P<0.01), shorter time to oral intake (WMD = -0.25, 95%CI: -0.49 to -0.01, P = 0.04), and more retrieved lymph nodes (WMD = 1.36, 95%CI: 0.30 to 2.43, P = 0.01). Operation time (WMD = -0.07, 95%CI -15.58 to 15.43, P = 0.99), overall postoperative complication rate (OR = 1.05, 95%CI: 0.74 to 1.49, P = 0.63), surgical complication rate (OR = 1.02, 95%CI: 0.70 to 1.49, P = 0.90), nonsurgical complication rate (OR = 1.21, 95%CI: 0.54 to 2.72, P = 0.64), leakage rate (OR = 2.54, 95%CI: 0.92 to 7.01, P = 0.07), stricture rate (OR = 0.36, 95%CI: 0.09 to 1.44, P = 0.15), wound complication rate (OR = 0.71, 95%CI: 0.33 to 1.55, P = 0.39), time to first flatus (WMD = -0.10, 95%CI: -0.27 to 0.07, P = 0.26), and proximal surgical margin (WMD = -0.25, 95%CI: -1.14 to 0.65, P = 0.59) was not statistically different. Compared with LADG BI, DA is a safe and feasible procedure, with significantly reduced blood loss, time to oral intake, and postoperative hospitalization.

Anastomotic leakage, bleeding, and stricture are major complications after gastrectomy. Of these complications, postoperative anastomotic bleeding is relatively rare, but lethal if not treated immediately. Of 2031 patients with gastric cancer who underwent radical gastrectomy (R0 resection) between January 2002 and December 2010, postoperative anastomotic bleeding was observed in 7 patients. The clinicopathological features, postoperative outcomes such as surgical procedures, bleeding sites and, methods used to achieve hemostasis, and the risk factors of anastomotic bleeding of these 7 patients were analyzed. Of the 2031 patients, 1613 and 418 underwent distal and total gastrectomy, respectively. The bleeding sites were as follows: Billroth-I anastomosis using a circular stapler (n = 1), Billroth-II anastomosis by manual suture (n = 5), and esophagojejunostomy using a circular stapler (n = 1). All patients were treated with endoscopic clipping or epinephrine injection. There was no further endoscopic intervention or reoperation for anastomotic bleeding. Postoperative anastomotic bleeding is an infrequent but potentially life-threatening complication. Scrupulous surgical procedures are essential for the prevention of postoperative bleeding, and endoscopy was useful for both the confirmation of bleeding and therapeutic intervention.

Rainville, Harvey; Ikedilo, Ojinika; Vemulapali, Pratibha

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

This paper presents a method for generating branching pattern reports of abdominal blood vessels for laparoscopic gastrectomy. In gastrectomy, it is very important to understand branching structure of abdominal arteries and veins, which feed and drain specific abdominal organs including the stomach, the liver and the pancreas. In the real clinical stage, a surgeon creates a diagnostic report of the patient anatomy. This report summarizes the branching patterns of the blood vessels related to the stomach. The surgeon decides actual operative procedure. This paper shows an automated method to generate a branching pattern report for abdominal blood vessels based on automated anatomical labeling. The report contains 3D rendering showing important blood vessels and descriptions of branching patterns of each vessel. We have applied this method for fifty cases of 3D abdominal CT scans and confirmed the proposed method can automatically generate branching pattern reports of abdominal arteries.

To evaluate methodological quality and the extent of concordance among meta-analysis and/or systematic reviews on surgical interventions for gastric cancer (GC). A comprehensive search of PubMed, Medline, EMBASE, the Cochrane library and the DARE database was conducted to identify the reviews comparing different surgical interventions for GC prior to April 2014. After applying included criteria, available data were summarized and appraised by the Oxman and Guyatt scale. Fifty six reviews were included. Forty five reviews (80.4%) were well conducted, with scores of adapted Oxman and Guyatt scale ≥ 14. The reviews differed in criteria for avoiding bias and assessing the validity of the primary studies. Many primary studies displayed major methodological flaws, such as randomization, allocation concealment, and dropouts and withdrawals. According to the concordance assessment, laparoscopy-assisted gastrectomy (LAG) was superior to open gastrectomy, and laparoscopy-assisted distal gastrectomy was superior to open distal gastrectomy in short-term outcomes. However, the concordance regarding other surgical interventions, such as D1 vs. D2 lymphadenectomy, and robotic gastrectomy vs. LAG were absent. Systematic reviews on surgical interventions for GC displayed relatively high methodological quality. The improvement of methodological quality and reporting was necessary for primary studies. The superiority of laparoscopic over open surgery was demonstrated. But concordance on other surgical interventions was rare, which needed more well-designed RCTs and systematic reviews.

Of this study is the introduction and the results evaluation of laparoscopic ultrasonography performed. 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.

Pylorus preserving loop duodeno-enterostomy with sleeve gastrectomy - preliminary results

PubMed Central

2014-01-01

Background Bariatric operations mostly combine a restrictive gastric component with a rerouting of the intestinal passage. The pylorus can thereby be alternatively preserved or excluded. With the aim of performing a “pylorus-preserving gastric bypass”, we present early results of a proximal postpyloric loop duodeno-jejunostomy associated with a sleeve gastrectomy (LSG) compared to results of a parallel, but distal LSG with a loop duodeno-ileostomy as a two-step procedure. Methods 16 patients underwent either a two-step LSG with a distal loop duodeno-ileostomy (DIOS) as revisional bariatric surgery or a combined single step operation with a proximal duodeno-jejunostomy (DJOS). Total small intestinal length was determined to account for inter-individual differences. Results Mean operative time for the second-step of the DIOS operation was 121 min and 147 min for the combined DJOS operation. The overall intestinal length was 750.8 cm (range 600-900 cm) with a bypassed limb length of 235.7 cm in DJOS patients. The mean length of the common channel in DIOS patients measured 245.6 cm. Overall excess weight loss (%EWL) of the two-step DIOS procedure came to 38.31% and 49.60%, DJOS patients experienced an %EWL of 19.75% and 46.53% at 1 and 6 months, resp. No complication related to the duodeno-enterostomy occurred. Conclusions Loop duodeno-enterosomies with sleeve gastrectomy can be safely performed and may open new alternatives in bariatric surgery with the possibility for inter-individual adaptation.

2017-02-01

This study aimed to compare midterm and long-term weight loss and resolution of co-morbidity with laparoscopic Roux-en-Y gastric bypass (LRYGB) and laparoscopic sleeve gastrectomy (LSG). LRYGB and LSG are the most common procedures performed in bariatric surgery. However, their weight loss efficacy in the midterm and long-term has not been well compared. A meta-analysis was performed by systematically identifying comparative studies conducted until the end of June 2016 that investigated weight loss outcome and resolution of co-morbidities (type 2 diabetes mellitus, hypertension, hyperlipidemia, hypertriglyceridemia, and obstructive sleep apnea) with LRYGB and LSG in the midterm (3-5 years) and long term (≥5 years). The primary endpoint was weight loss after LRYGB versus LSG. The secondary endpoint was resolution of co-morbidities after these procedures. Fourteen studies comprising 5264 patients were eligible. Follow-up ranged from 36 months to 75.8±8.4 months. The pooled result for weight loss outcomes did not show any significant difference in midterm weight loss (standardized mean difference = -0.03; 95% confidence interval (CI), -0.38-.33; P = .88) but a significant difference in the long-term weight loss outcome favoring LRYGB (standardized mean difference = .17; 95% CI, .05-.28; P= .005). The pooled results demonstrated no significant difference for resolution of type 2 diabetes mellitus, hypertension, hyperlipidemia, and hypertriglyceridemia. Despite the insignificant difference between LRYGB and LSG in midterm weight loss, LRYGB produced better weight loss in the long-term. There was no significant difference between the 2 procedures for co-morbidity resolution. Copyright © 2017 American Society for Bariatric Surgery. Published by Elsevier Inc. All rights reserved.

Single-Incision Laparoscopic Anterior Resection Using a Curved Stapler.

2016-11-01

Single-incision laparoscopic colectomy is technically limited because of such factors as instrument crowding, in-line viewing, and insufficient countertraction. In particular, it is technically difficult to cut the distal rectum from the umbilicus using an articulating linear stapler in single-incision laparoscopic anterior resection. After treating the mesorectum, the 5-mm trocar is replaced with a 12-mm trocar. The cartridge of the curved stapler is mounted while the shaft of the stapler is inserted into the 12-mm port extracorporeally. The curved stapler is inserted through the umbilical incision with the cartridge. A multichannel port is then mounted, and the abdominal cavity is reinsufflated. The curved stapler can then be operated intracorporeally. This procedure facilitates the vertical dissection of the rectum from the umbilicus. A total of 27 consecutive patients were analyzed in this study. All the procedures were safely performed without any complications. The median distance from the peritoneal reflection to the transection point of the distal bowel in single-incision laparoscopic anterior resection was 5.0 cm (range, -2.0 to 15.0). One stapler firing was required to achieve distal bowel division in 26 patients (96.3 %), whereas 2 firings were required in 1 patient (3.7 %). The median distal margin was 7.0 cm (range, 3.0-13.0). The time from the insertion of the stapler to transection was 180 seconds (range, 100-420). There were no cases of anastomotic leakage. In single-incision laparoscopic anterior resection, it is feasible to perform rectal transection from the umbilicus by using a curved stapler. This technique may allow for the omission of 1 trocar from the operation.

Ventriculoperitoneal shunts (VPS) are the primary treatment for hydrocephalus and are associated with a high risk of complications, specifically in patients who are obese or have abdominal adhesions or shunt revisions. The present study describes the use of a novel type of peritoneal catheter peritoneocentesis trocar insertion with the assistance of a one-port laparoscope. A total of 36 patients with hydrocephalus underwent this novel type of peritoneocentesis trocar-assisted VPS. The distal shunt catheter was placed into the right subdiaphragmatic space and the catheter was traversed through a single hole drilled through the liver falciform ligament. The duration of the laparoscopic surgery ranged from 6–18 min (mean 10.4±1.6 min). No shunt-related infections or catheter malfunctions or injuries to the intra-abdominal organs occurred. The total abdominal incision length was 1.0 cm (0.5+0.5 cm). No laparoscopy-related complications were observed during follow-up assessments. The novel approach used in the current study is very easy to perform, and this method may significantly reduce the risk of malfunction complications. The presented method also has the advantages of reduced trauma and a simpler surgery. The current study indicated that this simple, minimally invasive procedure was beneficial for patients with hydrocephalus, specifically in cases of patients with obesity, peritoneal adhesions or shunt revisions.

Among the most common early complications after bariatric surgery are anastomosis leak and bleeding. In order to react quickly and perform accurate treatment before the clinical signs appear, early predictors should be found. In the study C-reactive protein (CRP) and procalcitonin (PCT) levels were investigated. Characterized by a relatively short half-life, they can predict surgical complications. To develop and implement certain standards for early detection of complications. The study involved 319 adults who underwent laparoscopic sleeve gastrectomy (LSG) as a surgical intervention for morbid obesity at the Department of General Surgery of Ceynowa Hospital in Wejherowo. Every patient had CRP and PCT levels measured before the surgery and on the 1 st and 2 nd postoperative day (POD). Early postoperative complications occurred in 19 (5.96%) patients. Septic and non-septic complications occurred in 3 and 16 patients respectively. Among the patients with septic postoperative complications CRP level increased significantly on the 2 nd POD compared to the remainder (p = 0.0221). Among the patients with non-septic postoperative complications CRP level increased significantly on the 1 st and 2 nd POD compared to the remainder. Among the patients with septic and non-septic postoperative complications PCT level increased significantly on the 2 nd POD compared to the remainder. The CRP and PCT level are supposed to be relevant diagnostic markers to predict non-septic and septic complications after LSG.

Laparoscopic sleeve gastrectomy (LSG) has become a popular stand-alone treatment for morbid obesity. However, removal of the gastric specimen could be a challenging step due to its large size relative to the width of the trocar site. We aimed to compare a simplified retrieval technique for extraction of the gastric specimen without an endobag with conventionally performed specimen retrieval using an endobag. A case-control study was conducted recruiting patients undergoing LSG. Patient's demographics, preoperative characteristics, intra-operative, and postoperative variables were compared between the two groups according to the technique of gastric specimen removal. A total of 193 patients (60.6% female) were enrolled into case (n = 100) and control groups (n = 93). Mean ± SD age and BMI of patients were 35.64 ± 11.84 years and 47.28 ± 8.22 Kg/m 2 , respectively with no significant difference between groups. Median (25th, 75th inter-quartile), extraction time was significantly reduced in the non-endobag group compared to the endobag group (3.5 [2.5-4.5] min vs. 6.5 [3.4-8.2] min, p = 0.03).Patients of both groups had similar intra-operative and trocar site complications (hernia and wound infection) (3% for endobag group and 3.3 % for non-endobag group). The median (25-75% [IQR]) LOS was also comparable between endobag and non-endobag patients (3[2-3] vs. 3[2-4] days, p = 0.84). No difference was observed between the two groups for weight loss and comorbidity resolution. Non-endobag technique for gastric specimen retrieval is safe and feasible with substantial saving in operative time and comparable intra-operative and postoperative outcomes to the conventional retrieval technique.

The ideal reconstruction method for pancreaticoduodenectomy following a gastrectomy with Billroth II or Roux-en-Y reconstruction is unclear. We reviewed a series of seven pancreaticoduodenectomies performed after gastrectomy with the Billroth II or Roux-en-Y method. While preserving the existing gastrojejunostomy or esophagojejunostomy, pancreaticojejunostomy and hepaticojejunostomy were performed by the Roux-en-Y method using a new Roux limb in all cases. Four patients experienced postoperative complications, although the specific complications varied. A review of the literature revealed 13 cases of pancreaticoduodenectomy following gastrectomy with Billroth II or Roux-en-Y reconstruction. Three patients out of six (50%) in whom the past afferent limb was used for the reconstruction of the pancreaticojejunostomy and hepaticojejunostomy experienced afferent loop syndrome, while 14 previous and current patients in whom a new jejeunal limb was used did not experience this complication. The Roux-en-Y method, using the distal intestine of previous gastrojejunostomy or jejunojejunostomy as a new jejunal limb for pancreaticojejunostomy and hepaticojejunostomy, may be a better reconstruction method to avoid the complication of afferent loop syndrome after previous gastrectomy with Billroth II or Roux-en-Y reconstruction if the afferent limb is less than 40cm.

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

Transection of gastric tissue during laparoscopic sleeve gastrectomy (LSG) can be challenging. Reinforcing the staple line may decrease the incidence of issues requiring intervention. The objective of this study was to compare the number of intraoperative surgical interventions for a surgical stapler and reload system with Gripping Surface Technology (GST) to standard reloads in patients who underwent LSG. Patients who underwent elective LSG were enrolled. The study was conducted in two stages. For Stage 1, procedures were performed using a powered stapler and standard reloads. For Stage 2, a reload system with GST was used. The primary endpoint was surgical interventions for bleeding and/or staple line issues during transection of the greater curvature of the stomach. Propensity score matching was applied to create two groups similar in baseline characteristics and risk factors. A total of 111 subjects were enrolled across four centers. Propensity-matched procedures were completed with the standard (n = 38) or GST reloads (n = 38). The mean number of interventions in the standard group was 1.9 (1.29) versus 1.1 (1.45) in the GST group. Nonparametric comparisons were statistically significant, indicating a reduction in the distribution of interventions for GST subjects (P = .0036 for matched pair data). Tissue slippage during transection was low for both groups. Intraoperative leak testing was negative in all procedures, and no procedures were converted to open. Use of the GST stapling system reduces the need for staple line interventions in LSG. Both stapling systems had an acceptable safety profile.

Controversy persists regarding the technical feasibility of laparoscopic total gastrectomy (LTG), and to our knowledge, no prospective study with a sample size sufficient to investigate its safety has been reported. We aimed to compare the postoperative morbidity and mortality rates in patients undergoing LTG and open total gastrectomy (OTG) for gastric cancer in prospectively enrolled cohort using nationwide web-based registry. From August 2014 to July 2015, consecutive patients undergoing LTG or OTG (925 and 1569 patients, respectively) at the participating institutions were enrolled prospectively into the National Clinical Database registration system. We constructed propensity score (PS) models separately in four facility yearly case-volume groups, and evaluated the postoperative morbidity and mortality in PS-matched 1024 patients undergoing LTG or OTG. The incidence of overall morbidity were 84 (16.4%) in the OTG and 54 (10.3%) in the LTG groups (p = 0.01).The incidence of anastomotic leakage and pancreatic fistula grade B or above were not significantly different between the two groups (LTG 5.3% vs. OTG 6.1%, p = 0.59, LTG 2.7% vs. OTG 3.7%, p = 0.38, respectively). There were also no significant differences in the 30-day and in-hospital mortality rates between the two groups (LTG 0.2% vs. OTG 0.4%, p = 0.56; LTG 0.4% vs. OTG 0.4%, p = 1.00, respectively). The results from our nationally representative data analysis showed that LTG could be a safe procedure to treat gastric cancer compared to OTG. The indication for LTG should be considered carefully in a clinical setting.

The aim of this study was to assess intraoperative, postoperative, and oncologic outcome in patients undergoing laparoscopic distal pancreatectomy (LDP) versus open distal pancreatectomy (ODP) for benign and malignant lesions of the pancreas. Data from patients undergoing distal pancreatic resection were extracted from the StuDoQ|Pancreas registry of the German Society for General and Visceral Surgery. After propensity score case matching, groups of LDP and ODP were compared regarding demography, comorbidities, operative details, histopathology, and perioperative outcome. At the time of data extraction, the StuDoQ|Pancreas registry included over 3000 pancreatic resections from over 50 surgical departments in Germany. Data from 353 patients undergoing ODP (n = 254) or LDP (n = 99) from September 2013 to February 2016 at 29 institutions were included in the analysis. Baseline data showed a strong selection bias in LDP patients, which disappeared after 1:1 propensity score matching. A comparison of the matched groups disclosed a significantly longer operation time, higher rate of spleen preservation, more grade A pancreatic fistula, shorter hospital stay, and increased readmissions for LDP. In the small group of patients operated for pancreatic cancer, a lower lymph node yield with a lower lymph node ratio was apparent in LDP. LDP needed more time but potential advantages include increased spleen preservation and shorter hospital stay, as well as a trend for less transfusion, ventilation, and mortality. LDP for pancreatic cancer was performed rarely and will need critical evaluation in the future. Data from a prospective randomized registry trial is needed to confirm these results.

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

Billroth I gastroduodenostomy using a circular stapler is the most preferred reconstruction method after laparoscopy-assisted distal gastrectomy (LADG). The optimal stapler size for this procedure has not yet been proposed. Sixty-five patients who underwent LADG and stapled anastomosis with a 25-mm stapler (25-mm group) and a 29-mm stapler (29-mm group) were enrolled in this study. Clinical data and gastroscopic findings at 6 and 12 months after surgery were retrospectively reviewed. Postoperative complications and postprandial symptoms were similar in both groups. Gastroscopically, food materials remained more frequently in the remnant stomach in the 25-mm group than in the 29-mm group at 6 months after surgery (P=.041). Gastritis and bile reflux were observed more frequently in the 29-mm group than in the 25-mm group (P=.012 and P=.015, respectively). All these differences in the gastroscopic findings between the two groups decreased at 12 months after surgery except for reflux esophagitis, which was observed more frequently in the 29-mm group (P=.002). The length of the incision was smaller in the 25-mm group than in the 29-mm group (4.39 cm versus 4.95 cm, P=.009). A small-diameter stapler is a risk factor for gastric stasis in the early postoperative period, whereas a large-diameter stapler is a risk factor for gastritis and bile reflux in the early postoperative period and for esophagitis in the late postoperative period. Thus, a small-diameter circular stapler has more advantages over a large-diameter circular stapler. It also enables a reliable anastomosis through a smaller incision and easy handling of the stapler during anastomosis.

Rhabdomyolysis (RML) is a clinical and biochemical syndrome caused by destruction of skeletal muscles and constitutes a complication of bariatric surgery, with an incidence near to 22%. It is accompanied by increase in serum of intracellular enzymes. Laboratory data as predictive of prognosis have been evaluated by some authors. We report a case of RML after a sleeve gastrectomy, with good prognosis despite a very extensive muscle damage and very high seric and urinary peaks of intracellular enzymes. We describe a 34-years-old super-obese male (body mass index, 54.3 kg/m2) who underwent to laparoscopic sleeve gastrectomy. After 24 h, patient complained of pain in gluteal region, oliguria, and high levels of creatine phosphokinase that reached to 58,395 IU/l. Acute renal failure related to RML was diagnosed. Dialysis was not necessary. Ambulatorial control of renal function after dimission did not reveal a permanent damage. RML is a biochemical syndrome recently associated with bariatric surgery. Early diagnosis is ever necessary. Laboratory data represent markers for diagnosis and prognostic indicator of renal failure. There is no clear relation between seric levels of intracellular enzymes and irreversible renal damage and RML-related mortality.

Bariatric surgery has shown to be safe for patients over 60 years with good results especially considering resolving of comorbidities. Sleeve gastrectomy is considered to be safer than gastric bypass (GBP) and more effective than gastric banding with less adverse symptoms. Weight loss may be more modest than after GBP, but the effect on vitamins may also be milder. Since 2007, we collected prospectively 12-month follow-up data from 55 sleeve gastrectomy patients of whom 12 were over 59 years of age. Vitamin and calcium supplements were used postoperatively. The recovery from the operation was recorded during hospital stay, at 1- and 12-month follow-up visits using a standard protocol including laboratory tests. The results between patients over and under 59 years were compared. The preoperative weight and weight loss were comparable between the groups. Operation time was shorter and hospital stay was longer for older patients, p = ns. There was no operative mortality. Early major complications were seen more often in the older age group, 42% vs 9% (p = 0.02), but late complications were more common in younger patients, 17% vs 44%, p = ns. Early complications were mostly bleedings, which did not lengthen the hospital stay, neither were re-operations nor endoscopic procedures needed. Excess weight loss and resolving of comorbidities after 12 months was comparable between the groups. However, vitamin deficiencies and hypoalbuminemia were more common in the older age group, 42% and 23% for vitamins and 44% and 29% for proteins, p = ns. The older patients had more adverse effects related to surgery, 25% vs 9%, and younger had more adverse psychiatric effects, p = ns. Sleeve gastrectomy is effective and safe for older bariatric patients. Weight loss is comparable to younger patients and enough to resolve the comorbidities in most of the patients. With standardized nutritional supplementation, the older patients had more often vitamin deficiencies and

Obesity as a chronic disease has spread worldwide. Conservative treatment, especially with severe obesity, often fails. Obesity surgery has been shown to be an effective treatment. Laparoscopic sleeve gastrectomy (LSG), as a restrictive procedure, has low risks and results in good weight loss outcomes. However, to date, no studies have investigated the changes in psychological dimensions-especially concerning eating behavior and cognitive restraint-after LSG. The present study investigated, for the first time, eating behavior (cognitive restraint, disinhibition, hunger), depression, and perceived stress before and 1 year after LSG. The setting was a university hospital, comprehensive obesity center. Of 59 patients who had undergone LSG from 2008 to 2010, 40 patients were evaluated using questionnaires on eating behavior, depression, and stress, with measurements made before and 1 year after surgery. The body mass index had decreased, on average, by 15.5 kg/m(2) 1 year after LSG (62.7% excess weight loss). The eating behaviors had changed, with patients experiencing less hunger, fewer food cravings, and decreased disinhibition. Depressive symptoms and perceived stress improved. However, the results showed high levels in the dimension of cognitive restraint of eating 1 year after LSG. Most psychological dimensions improved as expected. The patients were less distracted by food, experienced less hunger, and were less disturbed by emotional distress. However, we found persistent cognitive restraint, reflecting an ongoing need for central eating control. Additional investigations are needed to describe the communication between the gut and brain after surgery. Copyright © 2013 American Society for Metabolic and Bariatric Surgery.

Laparoscopic sleeve gastrectomy (LSG) is a therapeutic option in severely obese patients. The aim of this study was to evaluate the presence of Helicobacter pylori (HP) gastritis and non-Helicobacter gastritis in the gastrectomy specimens, and its association to other variables.One hundred six sleeve gastrectomy specimens were examined histopathologically for the presence of gastritis and its relation to other factors like ethnicity, glycemic control, and postoperative complications.Twelve patients had HP gastritis, 39 had non-HP gastritis, and 55 had normal mucosa. There was a statistical difference between the Arab and Jewish Israeli patients in our study. Twenty-eight of the Arab patients had HP gastritis and 48% had non-HP gastritis. In the Jewish population 6% had HP gastritis and 34% had non-HP gastritis. The preoperative glycemic control was worse in the gastritis group with a mean HbA1c of 8.344% while in the normal mucosa group the mean HbA1c was 6.55. After operation the glycemic control reverted to normal in most the diabetic patients. There were few postoperative complications however, they were not related to HP.There is a high incidence of gastritis in obese patients. The incidence of gastritis in the Arab population in our study was higher than that in the Jewish population. The glycemic control before surgery was worse in patients with gastritis than in the normal mucosa group. HP bares no risk for postoperative complications after LSG and does not affect weight loss. However a larger cohort of patients must be studied to arrive at conclusive results.

To investigate the necessity and correctness of acid suppression pre- and post-gastrectomy among gastric carcinoma (GC) patients. From June 2011 to April 2013, 99 patients who were diagnosed with GC or adenocarcinoma of the gastroesophageal junction (type II or III) and needed surgical management were enrolled. They all underwent gastrectomy by the same operators [35 undergoing total gastrectomy (TG) plus Roux-en-Y reconstruction, 34 distal gastrectomy (DG) plus Billroth I reconstruction, and 30 proximal gastrectomy (PG) plus gastroesophagostomy]. We collected and analyzed their gastrointestinal juice and tissues from the pre-operational day to the 5(th) day post-operation, and 6 mo post-surgery. Gastric pH was detected with a precise acidity meter. Gastric juice contents including potassium, sodium and bicarbonate ions, urea nitrogen, direct and indirect bilirubin, and bile acid were detected using Automatic Biochemical Analyzer. Data regarding tumor size, histological type, tumor penetration and tumor-node-metastasis (TNM) stage were obtained from the pathological records. Reflux symptoms pre- and 6 mo post-gastrectomy were evaluated by reflux disease questionnaire (RDQ) and gastroesophageal reflux disease questionnaire (GERD-Q). SPSS 16.0 was applied to analyze the data. Before surgery, gastric pH was higher than the threshold of hypoacidity (4.25 ± 1.45 vs 3.5, P = 0.000), and significantly affected by age, tumor size and differentiation grade, and potassium and bicarbonate ions; advanced malignancies were accompanied with higher pH compared with early ones (4.49 ± 1.31 vs 3.66 ± 1.61, P = 0.008). After operation, gastric pH in all groups was of weak-acidity and significantly higher than that pre-gastrectomy; on days 3-5, comparisons of gastric pH were similar between the 3 groups. Six months later, gastric pH was comparable to that on days 3-5; older patients were accompanied with higher total bilirubin level, indicating more serious reflux (r = 0.238, P

AIM To investigate the role of minimally invasive surgery for gastric cancer and determine surgical, clinical, and oncological outcomes. METHODS This is a propensity score-matched case-control study, comparing three treatment arms: robotic gastrectomy (RG), laparoscopic gastrectomy (LG), open gastrectomy (OG). Data collection started after sharing a specific study protocol. Data were recorded through a tailored and protected web-based system. Primary outcomes: harvested lymph nodes, estimated blood loss, hospital stay, complications rate. Among the secondary outcomes, there are: operative time, R0 resections, POD of mobilization, POD of starting liquid diet and soft solid diet. The analysis includes the evaluation of type and grade of postoperative complications. Detailed information of anastomotic leakages is also provided. RESULTS The present analysis was carried out of 1026 gastrectomies. To guarantee homogenous distribution of cases, patients in the RG, LG and OG groups were 1:1:2 matched using a propensity score analysis with a caliper = 0.2. The successful matching resulted in a total sample of 604 patients (RG = 151; LG = 151; OG = 302). The three groups showed no differences in all baseline patients characteristics, type of surgery (P = 0.42) and stage of the disease (P = 0.16). Intraoperative blood loss was significantly lower in the LG (95.93 ± 119.22) and RG (117.91 ± 68.11) groups compared to the OG (127.26 ± 79.50, P = 0.002). The mean number of retrieved lymph nodes was similar between the RG (27.78 ± 11.45), LG (24.58 ± 13.56) and OG (25.82 ± 12.07) approach. A benefit in favor of the minimally invasive approaches was found in the length of hospital stay (P < 0.0001). A similar complications rate was found (P = 0.13). The leakage rate was not different (P = 0.78) between groups. CONCLUSION Laparoscopic and robotic surgery can be safely performed and proposed as possible alternative to open surgery. The main highlighted benefit is a faster

To investigate the clinical advantage of the application of modified Roux-en-Y reconstruction after totally laparoscopic total gastrectomy. Clinical data of 36 patients who underwent totally laparoscopic total gastrectomy with Roux-en-Y reconstruction by one medical team for gastric adenocarcinoma between January 2014 and December 2014 in the Second Hospital of Jilin University were retrospectively analyzed. Patients were divided into classic Roux-en-Y group (CRY, 16 cases) and modified Roux-en-Y group (MRY, 20 cases) according to reconstructive methods. The data concerning the intraoperative and postoperative situation in two groups were compared. Operation was successfully completed in all the cases without conversion to laparotomy. Compared to CRY group, MRY group had shorter mean operative time [(260.9 ± 21.2) min vs. (287.9 ± 19.0) min, P=0.000], shorter mean reconstruction duration [(32.4 ± 9.2] min vs. (45.4 ± 13.2) min, P=0.001] and less intraoperative bleeding [(50.9 ± 23.5) ml vs. (67.0 ± 20.5) ml, P=0.000]. Jejunum mesentery dissection and jejunum resection were not necessary in MRY group. However, there were no significant differences in lymph nodes harvested, time to flatus, hospital stay and postoperative complications between two groups. As compared to classic Roux-en-Y reconstruction, the modified Roux-en-Y reconstruction can simplify the surgical procedures and achieve similar efficacy. It is feasible and safe, and worth further promotion in clinical practice.

The incidence of gallstones and gallbladder sludge is known to be higher in patients after gastrectomy than in general population. This higher incidence is probably related to surgical dissection of the vagus nerve branches and the anatomical gastrointestinal reconstruction. Therefore, some surgeons perform routine concomitant cholecystectomy during standard surgery for gastric malignancies. However, not all the patients who are diagnosed to have cholelithiasis after gastric cancer surgery will develop symptoms or require additional surgical treatments and a standard laparoscopic cholecystectomy is feasible even in those patients who underwent previous gastric surgery. At the present, no randomized study has been published and the decision of gallbladder management is left to each surgeon preference. The study is a randomized controlled investigation. The study will be performed in the General and Oncologic Surgery, Department of Oncology-Azienda Ospedaliero-Universitaria Careggi-Florence-Italy, a large teaching institution, with the participation of all surgeons who accept to be involved in, together with other Italian Surgical Centers, on behalf of the GIRCG (Italian Research Group for Gastric Cancer).The patients will be randomized into two groups: in the first group the patient will be submitted to prophylactic cholecystectomy during standard surgery for curable gastric cancer (subtotal or total gastrectomy), while in the second group he/she will be submitted to standard gastric surgery only.

The aim of this study is to investigate the effects of sleeve gastrectomy on hormone replacement therapy and on hypothalamic obesity in patients affected by craniopharyngioma with post-surgical pan-hypopituitarism. A retrospective review of three patients, treated for hypothalamic obesity with laparoscopic sleeve gastrectomy, who have previously undergone surgery for craniopharyngioma in their childhood, was done. Patients' mean age and BMI were 22.3 years (range 21-24) and 49.2 kg/m 2 (range 41.6-58.1), respectively. The mean time of delay between neurosurgery and bariatric surgery was 12.3 years (range 6-16). There were no major complications or deaths. At 24 months follow-up, the mean BMI was 35.3 kg/m 2 (range 31.2-40.6). No hydrocortisone and sex steroids dose changes were observed, while levothyroxine was decreased in two patients. Growth hormone replacement therapy was increased in two patients, whereas it was started in one patient. Desmopressin was significantly decreased in all of them. Patients with surgically induced pan-hypopituitarism after craniopharyngioma who become obese, can expect good results from sleeve gastrectomy: this procedure does not have significant negative effects on hormone substitution and leads to a good stabilization of body weight in a mid-term follow-up.

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

Laparoscopic sleeve gastrectomy (LSG) is a widely accepted, stand-alone bariatric operation. Data on elderly patients undergoing LSG are scarce. The aim of this study was to demonstrate that LSG is safe and effective for patients>65 years old with severe obesity. Department of Minimally Invasive Digestive Surgery, Antoine-Beclere Hospital, AP-HP, Paris-Saclay University, France. Prospectively collected data from consecutive patients undergoing LSG were retrospectively analyzed. Patients with>1-year follow-up were included in the analysis for weight loss and co-morbidities evaluation. Quality of life was evaluated using the Short-Form 36 questionnaire. Fifty-four patients>65 years old (range, 65-75 yr) underwent LSG. Median weight was 119 kg, and median body mass index was 43 kg/m 2 . Median duration of surgery was 86.5 minutes. Two patients (3.7%) suffered a gastric staple-line leak, 1 treated by pure endoscopic internal drainage and 1 by relaparoscopy with subsequent endoscopic internal drainage. Mortality was null. Median length of hospital stay was 5 days. Six, 12, and 24 months after LSG, median body mass index decreased significantly to 35, 32.9, and 30.7 kg/m 2 , respectively (P<.0001), with mean excess weight loss of 76.3% at 2 years. Type 2 diabetes, hypertension, dyslipidemia, obstructive sleep apnea syndrome, and arthralgia showed statistically significant remission at 1- and 2-year follow-up, while 6 of 8 SF-36 scale scores of quality of life assessment improved significantly. This study suggests that LSG is effective for patients>65 years old, resulting in significant weight loss, co-morbidities remission, and quality of life improvement. Careful patient selection after adequate risk versus benefit evaluation by an expert multidisciplinary team is essential for patient safety and optimal results.

Obesity is an epidemic in the USA that continues to grow, becoming a leading cause of premature avoidable death. Bariatric surgery has become an effective solution for obesity and its comorbidities, and one of the most commonly utilized procedures, the sleeve gastrectomy, can lead to an increase in gastroesophageal reflux following the operation. While these data are controversial, sometimes operative intervention can be necessary to provide durable relief for this problem. We performed an extensive literature review examining the different methods of anti-reflux procedures that are available both before and after a sleeve gastrectomy. We reviewed several different types of anti-reflux procedures, including those that supplement the lower esophageal sphincter anatomy, such as magnetic sphincter augmentation and radiofrequency ablation procedures. Re-operation was also discussed as a possible treatment of reflux in sleeve gastrectomy, especially if the original sleeve becomes dilated or if a conversion to a Roux-en-Y gastric bypass or biliopancreatic diversion is deemed necessary. Sleeve gastrectomy with concomitant anti-reflux procedure was also reviewed, including the anti-reflux gastroplasty, hiatal hernia repair, and limited fundoplication. A number of techniques can be used to mitigate the severity of reflux, either by maintaining the normal anatomic structures that limit reflux or by supplementing these structures with a plication or gastroplasty. Individuals with existing severe reflux should not be considered for a sleeve gastrectomy. New techniques that incorporate plication at the time of the index sleeve gastrectomy show some improvement, but these are in small series that will need to be further evaluated. The only proven method of treating intractable reflux after sleeve gastrectomy is conversion to a Roux-en-Y gastric bypass.

In some studies, gum-chewing was demonstrated to have a beneficial effect on resumption of bowel function; however, other contradictory findings in other studies refute the effects of gum-chewing on peristaltic movements and digestive system stimulation. In addition, most previous studies were after colorectal or gynecology surgery, whereas few reports focused on the effect of gum-chewing after gastrectomy. The aim of this randomized controlled trial was to assess the effectiveness of gum-chewing on postoperative bowel function in patients who had undergone laparoscopic gastrectomy. From March 2014 to March 2016, 75 patients with gastric cancer received elective laparoscopic surgery in Shanghai Tongji hospital and were postoperatively randomly divided into 2 groups: 38 in a gum-chewing (Gum) group and 37 in a control (No gum) group. The patients in the Gum group chewed sugarless gum 3 times daily, each time for at least 15 minutes, until the day of postoperative exhaust defecation. The mean time to first flatus (83.4 ± 35.6 vs. 79.2 ± 24.2 hours; P = 0.554) and the mean time to first defecation (125.7 ± 41.2 vs. 115.4 ± 34.2 hours; P = 0.192) were no different between the no gum and Gum groups. There was also no significant difference in the incidence of postoperative ileus (P = 0.896) and postoperative hospital stay (P = 0.109) between the 2 groups. The postoperative pain score at 48 hours (P = 0.032) in the Gum group was significantly higher than in the no gum group. There was no significant difference between the 2 groups in regards to patient demographics, comorbidities, duration of surgery, complications, and nausea/vomiting score. Gum-chewing after laparoscopic gastrectomy did not hasten the return of gastrointestinal function. In addition, gum-chewing may increase patient pain on the second postoperative day.

Endoscopic submucosal dissection (ESD) for early gastric cancer (EGC) after surgical gastrectomy is a technically difficult procedure because of the limited working space in the remnant stomach as well as the presence of severe gastric fibrosis and staples under the suture line. We evaluated clinical results including long-term outcomes to determine the feasibility and effectiveness of ESD for EGC in the remnant stomach of patients after gastrectomy. Retrospective study. National Cancer Center Hospital, Tokyo, Japan. We investigated patients undergoing ESD for EGC in the remnant stomach from 1997 to 2011. We examined the patient characteristics, endoscopic findings, technical results, adverse events, and histopathologic results including curability and evaluations of Helicobacter pylori gastritis in addition to the rates of local recurrence, metachronous gastric cancer, overall survival, and cause-specific survival. A total of 128 consecutive patients with 139 lesions had previously undergone 87 distal (68%), 25 proximal (19.5%) and 16 pylorus-preserving gastrectomies (12.5%). The median period from the original gastrectomy to the subsequent ESD for EGC in the remnant stomach was 5.7 years (range 0.6-51 years), the median tumor size was 13 mm (range 1-60 mm), and the median procedure time was 60 minutes (range 15-310 minutes). There were 131 en bloc resections (94%), with curative resections achieved for 109 lesions (78%); 22 lesions (16%) resulted in non-curative resections, and 8 lesions (6%) had only a horizontal margin positive or had inconclusive results. A total of 118 patients (92%) were assessed as H pylori gastritis-positive, with 7 patients (5%) negative. Adverse events included 2 cases of delayed bleeding (1.4%) and 2 perforations (1.4%), with 1 patient requiring emergency surgery. The 5-year overall and cause-specific survival rates were 87.3% and 100%, respectively, during a median follow-up period of 4.5 years (range 0-13.7 years), with no deaths from

The improvement of quality of life is of great importance in managing patients with far-advanced gastric cancer. We report a new cure and less invasive method of creating a stomach-partitioning gastrojejunostomy in reduced-port laparoscopic surgery for unresectable gastric cancers with gastric outlet obstruction. A 2.5-cm vertical intraumbilical incision was made, and EZ Access (Hakko Co., Ltd., Tokyo, Japan) was placed. After pneumoperitoneum was created, an additional 5-mm trocar was inserted in the right upper abdomen. A gastrojejunostomy was performed in the form of an antiperistaltic side-to-side anastomosis, in which the jejunal loop was elevated in the antecolic route and anastomosed to the greater curvature of the stomach using an endoscopic linear stapler. The jejunal loop together with the stomach was dissected with additional linear staplers just proximal to the common entry hole so that a functional end-to-end gastrojejunostomy was completed. At the same time, the stomach was partitioned using a linear stapler to leave a 2-cm-wide lumen in the lesser curvature. Subsequently, jejunojejunostomy was performed 30 cm distal to the gastrojejunostomy, and the stomach-partitioning gastrojejunostomy resembling Roux-en Y anastomosis was completed. All patients resumed oral intake on the day of operation. Neither anastomotic leakage nor anastomotic stricture was observed. Our less invasive palliative operation offers the utmost priority to improve quality of life for patients with unresectable gastric cancer.

Gallstone ileus is an uncommon cause of small bowel obstruction. When the gallstone lodges inside the duodenum and causes gastric outlet obstruction, it is termed Bouveret's syndrome. However, it is rather unusual to seen the evolution of a migrating gallstone (from duodenum to distal small bowel) in a patient during the same hospital admission. We report a case of gallstone ileus from the initial presentation of gastric outlet obstruction to the development of distal small bowel obstruction within the same hospital admission, and its total laparoscopic treatment.

The aim of this study is the evaluation of laparoscopic treatment in abdominal complications following ventriculoperitoneal (VP) shunt. Methods: We report a retrospective study including 17 patients with abdominal complications secondary to VP shunt for hydrocephalus, laparoscopically treated in our department, between 2000 and 2007. Results: Patients' age ranged from 1 to 72 years old (mean age 25.8 years old). Male: female ratio was 1.4. Abdominal complications encountered were: shunt disconnection with intraperitoneal distal catheter migration 47.05% (8/17), infections 23.52% (4/17) such as abscesses and peritonitis, pseudocysts 11.76% (2/17), CSF ascites 5.88% (1/17), inguinal hernia 5.88% (1/17), and shunt malfunction due to excessive length of intraperitoneal tube 5.88% (1/17). Free–disease interval varies from 1 day to 21 years, depending on the type of complication, short in peritoneal irritation syndrome and abscesses (days) and long in ascites, pseudocysts(months– years). Laparoscopic treatment was: extraction of the foreign body in shunt disconnection with intraperitoneal distal catheter migration, evacuation, debridement, lavage and drainage for pseudocysts, abscess and peritonitis, shortening of the tube in shunt malfunction due to excessive length of intraperitoneal tube a nd hernioraphy. One diagnostic laparoscopy was performed in a peritoneal irritation syndrome, which found only CSF ascites. There were no conversions to open surgery. The overall mortality was of 5.88% and postoperative morbidity was of 11.76%. In 7 patients operated for abscesses, peritonitis, pseudocysts, and CSF ascites the shunting system was converted in to a ventriculocardiac shunt. Conclusions: Abdominal complication following VP shunt can be successfully performed laparoscopically. Abdominal surgery required, in selected cases, the repositioning of the distal catheter, frequently as a ventriculocardiac shunt. There are abdominal complications with no indication of

Laparoscopic sleeve gastrectomy (LSG) reduces obesity-related co-morbidities, such as diabetes, hypertension, and hyperlipidemia. Endocrinological abnormalities may occur as undesired side effects. Most centers routinely prescribe folic acid, cyanocobalamin (vitB12), and protein replacement in the postoperative period, but 25-OH-vitamin-D3 (vitD) and intact parathyroid hormone (iPTH) levels are not routinely followed up. The aim of this study was to identify the effects of LSG on iPTH, vitD, calcium (Ca), phosphorus (P), alkaline phosphatase (ALP), and albumin levels. Data of morbidly obese patients who underwent LSG between January and December 2014 were studied in this prospectively designed study. Serum levels of iPTH, vitD, Ca, P, folic acid, vitB12, ALP, and albumin were measured preoperatively and postoperatively at the 3rd, 6th, and 12th months. In total, 119 patients were analyzed. All patients had normal iPTH, vitD, Ca, P, folic acid, vitB12, ALP, and albumin values preoperatively, and 31.6% had received vitD supplementation during their nutritionist observation time before surgery. At the 3rd, 6th, and 12th postoperative months, 21 (17.6%), 17 (17.3%), and 1 (0.8%) patients, respectively, had increased iPTH and ALP and decreased vitD levels. A total of 39 (32.7%) patients needed high-dose vitD treatment during a 1 year follow-up. Approximately 37.5% of the patients who received vitD supplementation preoperatively needed vitD supplementation postoperatively. Hospital records of 101 of 119 patients who underwent LSG could be screened to determine their vitD supplementation requirements previously ordered by their nutritionist for a 1-year period before LSG. Thirty-two (31.6%) of the 101 patients had received vitD supplementation during the 1-year period preoperatively. Although serum levels of iPTH, vitD, Ca, P, vitB12, ALP, and albumin may be normal preoperatively, severe vitD insufficiency requiring high-dose vitD replacement may develop in morbidly

Studies comparing Billroth-I (B-I) with Roux-en-Y (R-Y) anastomosis are still lacking and inconsistent. The aim of this trial was to compare the quality of life (QoL) of B-I with R-Y reconstruction after curative distal gastrectomy for gastric cancer. A total of 140 patients were randomly assigned to the B-I group (N = 70) and R-Y group (N = 70) with the comparable baseline characteristics. The overall postoperative morbidity rates were 18.6% and 25.7% in the B-I group and R-Y group without significant difference. More estimated blood loss and longer surgical duration were found in the R-Y group. At the postoperative 1 year time point, the B-I group had a higher score in pain, but lower score in global health. However, the R-Y anastomosis was associated with lower incidence of reflux symptoms at postoperative 6 months (P = 0.002) and postoperative 9 months (P = 0.007). The multivariable analyses of variance did not show any interactions between the time trend and grouping. For the results of endoscopic examination, the degree and extent of remnant gastritis were milder significantly in the R-Y group. The stronger anti-reflux capability of R-Y anastomosis contributes to the higher QoL by reducing the reflux related gastritis and pain symptoms, and promotes a better global health.

Distal pancreatectomy (DP) is the removal of the pancreatic tissue at the left side of the superior mesenteric vein and it is traditionally approached by an open or laparoscopic exposure. Preservation of the spleen is optional but appears to have a better immunological outcome. We present the case of a 53-year old patient with a 2.4/2.2 tumor located in the tail of the pancreas, with high tumour marker values for whom we decided to perform a robotic spleen-preserving distal pancreatectomy (RSPDP). The postoperative outcome was satisfactory. In conclusion, we recommend this type of approach for small pancreatic tail lesions.

Pancreatic mucinous cystic neoplasms (MCNs) are rare tumors typically of the distal pancreas that harbor malignant potential. Although resection is recommended, data are limited on optimal operative approaches to distal pancreatectomy for MCN. MCN resections (2000-2014; eight institutions) were included. Outcomes of minimally invasive and open MCN resections were compared. A total of 289 patients underwent distal pancreatectomy for MCN: 136(47%) minimally invasive and 153(53%) open. Minimally invasive procedures were associated with smaller MCN size (3.9 vs 6.8 cm; P = 0.001), lower operative blood loss (192 vs 392 mL; P = 0.001), and shorter hospital stay(5 vs 7 days; P = 0.001) compared with open. Despite higher American Society of Anesthesiologists class, hand-assisted (n = 46) had similar advantages as laparoscopic/robotic (n = 76). When comparing hand-assisted to open, although MCN size was slightly smaller (4.1 vs 6.8 cm; P = 0.001), specimen length, operative time, and nodal yield were identical. Similar to laparoscopic/robotic, hand-assisted had lower operative blood loss (161 vs 392 mL; P = 0.001) and shorter hospital stay (5 vs 7 days; P = 0.03) compared with open, without increased complications. Hand-assisted laparoscopic technique is a useful approach for MCN resection because specimen length, lymph node yield, operative time, and complication profiles are similar to open procedures, but it still offers the advantages of a minimally invasive approach. Hand-assisted laparoscopy should be considered as an alternative to open technique or as a successive step before converting from total laparoscopic to open distal pancreatectomy for MCN.

Laparoscopic sleeve gastrectomy has become a popular bariatric surgery in recent years. However, it has been linked to worsening or newly developed gastroesophageal reflux disease (GERD) in the postoperative period. The purpose of this study is to determine the safety and effectiveness of anterior fundoplication sleeve gastrectomy in patients with reflux. Academic hospital, United States. We prospectively collected data on 31 sleeve gastrectomy patients who concurrently underwent anterior fundoplication between July 2014 and March 2016. Patients were selected when they reported severe reflux before the procedure. Each patient was interviewed using the GERD score questionnaire (scaled severity and frequency of heartburn, regurgitation, epigastric pain, epigastric fullness, dysphagia, and cough) before and 4 months after the procedure. Our patients comprised 27 females and 4 males with a mean age of 49.9±9.6 years (range, 29-63 yr). They had a mean preoperative body mass index of 42.8±5.6 kg/m 2 (range, 33.3-58.4 kg/m 2 ), and 67.7% (n = 21) of these patients underwent hiatal hernia repair as well. Preoperatively, patients had a mean heartburn score of 7.4±3.6 (range, 1-12), regurgitation score of 5.4±4.1 (range, 0-12), epigastric pain score of 2.1±3.2 (range, 0-12), epigastric fullness score of 2.7±3.9 (range, 0-12), dysphagia score of 1.3±2.2 (range, 0-9), and cough score of .9±1.8 (range, 0-6). Mean preoperative GERD score was 18.9±9.8 (range, 6-36) in these patients. Patients were interviewed with the same questionnaire approximately 4 months postoperative. Patients had a mean heartburn score of 1.5±3.2 (range, 0-12), regurgitation score of .9±1.7 (range, 0-8), epigastric pain score of .4±1.1 (range, 0-4), epigastric fullness score of 1.1±2.4 (range, 0-8), dysphagia score of .3±1.1 (range, 0-6), and cough score of 0. Mean postoperative GERD score dropped down to 4.1±5.8 (range, 0-28), and the difference was statistically significant (P<.01). One

Hepatitis B virus (HBV) transmission is known to occur through direct contact with infected blood. There has been some suspicion that the virus can also be detected in aerosol form. However, this has never been directly shown. The purpose of this study was to sample and analyse surgical smoke from laparoscopic surgeries on patients with hepatitis B to determine whether HBV is present. A total of 11 patients who underwent laparoscopic or robotic abdominal surgeries between October 2014 and February 2015 at Korea University Anam Hospital were included in this study. A high efficiency collector was used to obtain surgical smoke in the form of hydrosol. The smoke was analysed by using nested PCR. Robotic or laparoscopic colorectal resections were performed in 5 cases, laparoscopic gastrectomies in 3 cases and laparoscopic hepatic wedge resections in another 3 cases. Preoperatively, all of the patients had positive hepatitis B surface antigen (HBsAg). 2 patients had detectable HBsAb, and 2 were positive for hepatitis B e antigen. 3 patients were taking antihepatitis B viral medications at the time of the study. The viral load measured in the patients' blood was undetectable to 1.7×10 8  IU/mL. HBV was detected in surgical smoke in 10 of the 11 cases. HBV is detectable in surgical smoke. This study provides preliminary data in the investigation of airborne HBV infection. Published by the BMJ Publishing Group Limited.

This multicenter, randomized controlled study evaluates the safety of early oral feeding following gastrectomy, and its effect on the length of postoperative hospital stay. The subjects of this study were patients who underwent distal gastrectomy (DG) or total gastrectomy (TG) for gastric cancer between January 2014 and December 2015. Patients were randomly assigned to the early oral feeding group (intervention group) or the conventional postoperative management group (control group) for each procedure. We evaluated the length of postoperative hospital stay and the incidence of postoperative complications in each group. No significant differences in length of postoperative stay were found between the intervention and control groups of the patients who underwent DG. The incidence of postoperative complications was significantly greater in the DG intervention group. In contrast, the length of postoperative stay was significantly shorter in the TG intervention group, although the TG group did not attain the established target sample size. Early oral feeding did not shorten the postoperative hospital stay after DG. The higher incidence of postoperative complications precluded the unselected adoption of early oral feeding for DG patients. Further confirmative studies are required to definitively establish the potential benefits of early oral feeding for TG patients.

Although Roux-en-Y (R-Y) reconstruction after distal gastrectomy has several advantages, such as prevention of bile reflux into the remnant stomach, it is rarely used because of the technical difficulty. This prospective randomized clinical trial aimed to show the efficacy of a novel method of R-Y reconstruction involving the use of 2 circular staplers by comparing this novel method to Billroth-I (B-I) reconstruction. A total of 118 patients were randomly allocated into the R-Y (59 patients) and B-I reconstruction (59 patients) groups. R-Y anastomosis was performed using two circular staplers and no hand sewing. The primary end-point of this clinical trial was the reflux of bile into the remnant stomach evaluated using endoscopic and histological findings at 6 months after surgery. No significant differences in clinicopathological findings were observed between the 2 groups. Although anastomosis time was significantly longer for the patients of the R-Y group (P<0.001), no difference was detected between the 2 groups in terms of the total surgery duration (P=0.112). Endoscopic findings showed a significant reduction of bile reflux in the remnant stomach in the R-Y group (P<0.001), and the histological findings showed that reflux gastritis was more significant in the B-I group than in the R-Y group (P=0.026). The results of this randomized controlled clinical trial showed that compared with B-I reconstruction, R-Y reconstruction using circular staplers is a safe and feasible procedure. This clinical trial study was registered at www.ClinicalTrials.gov (registration No. NCT01142271).

In adults undergoing gastric bypass surgery, it is routine practice to perform pre-operative testing for Helicobacter pylori infection. Evidence suggests that infection impairs anastomotic healing and contributes to complications. There currently are no data for adolescents undergoing bariatric procedures. Despite few patients with pre-operative symptoms, we noted occasional patients with H. pylori detected after sleeve gastrectomy. We reviewed our experience with our adolescent sleeve gastrectomy cohort to determine the prevalence of H. pylori infection, its predictive factors, and association with outcomes. We hypothesized that H. pylori infection would be associated with pre-operative symptoms, but not surgical outcomes. All patients undergoing sleeve gastrectomy at our hospital were included. We conducted a chart review to determine pre- or post-operative symptoms of gastroesophageal reflux disease GERD or gastritis, operative complications, and long-term anti-reflux therapy after surgery. Pathology reports were reviewed for evidence of gastritis and H. pylori infection. 78 adolescents had laparoscopic sleeve gastrectomy from January 2010 through July 2014. The prevalence of chronic gastritis was 44.9% (35/78) and 11.4% of those patients had H. pylori (4/35). Only one patient with H. pylori had pre-operative symptoms, and only 25.7% (9/35) of patients with pathology-proven gastritis had symptoms. One staple line leak occurred but this patient did not have H. pylori or gastritis. Mean patient follow-up was 10 (3-26) mos. There is a moderate prevalence of gastritis among adolescents undergoing sleeve gastrectomy, but only a small number of these patients had H. pylori infection. Neither the presence of chronic gastritis nor H. pylori infection correlated with symptoms or outcomes. Thus, in the absence of predictive symptomology or adverse outcome in those who are infected, we advocate for continued routine pathologic evaluation without the required need for pre

Radical resection by multivisceral resection of colorectal T4 tumours is important to reduce local recurrence and improve survival. Oncological safety of laparoscopic resection of T4 tumours is controversial. However, robot-assisted resections might have advantages, such as 3D view and greater range of motion of instruments. The aim of this study is to evaluate the initial results of robot-assisted resection of T4 rectal and distal sigmoid tumours. This is a cohort study of a prospectively kept database of all robot-assisted rectal and sigmoid resections between 2012 and 2017. Patients who underwent a multivisceral resection for tumours appearing as T4 cancer during surgery were included. Rectal and sigmoid resections are routinely performed with the DaVinci robot, unless an indication for intra-operative radiotherapy exists. 28 patients with suspected T4 rectal or sigmoid cancer were included. Most patients (78%) were treated with neoadjuvant chemoradiotherapy (n = 19), short course radiotherapy with long waiting interval (n = 2) or chemotherapy (n = 1). En bloc resection was performed with the complete or part of the invaded organ (prostate, vesicles, bladder, abdominal wall, presacral fascia, vagina, uterus, adnex). In 3 patients (11%), the procedure was converted to laparotomy. Twenty-four R0-resections were performed (86%) and four R1-resections (14%). Median length of surgery was 274 min (IQR 222-354). Median length of stay was 6 days (IQR 5-11). Twelve patients (43%) had postoperative complications: eight (29%) minor complications and four (14%) major complications. There was no postoperative mortality. Robot-assisted laparoscopy seems to be a feasible option for the resection of clinical T4 cancer of the distal sigmoid and rectum in selected cases. Radical resections can be achieved in the majority of cases. Therefore, T4 tumours should not be regarded as a strict contraindication for robot-assisted surgery.

To compare proximal gastrectomy (PG) with total gastrectomy (TG) for proximal gastric carcinoma, through the 5-year survival rate, recurrence rate, postoperative complications, and long-term life quality. The meta-analysis was carried out in the General Surgery Department of the Second Affiliated Hospital of Soochow University, Suzhou, Jiangsu Province, China. We searched Medline, EMBASE, and the Cochrane Library from June to November 2012. The literature searches were carried out using medical subject headings and free-text word: `proximal gastrectomy` `total gastrectomy` `partial gastrectomy` `stomach neoplasms` and `gastric cancer`. Two different reviewers carried out the search and evaluated studies independently. Two randomized controlled trials and 9 retrospective studies were included. A total of 1364 patients were included in our study. Our analysis showed that there is no statistically significant difference in 5-year survival rate between PG and TG (60.9% versus 64.4%). But, the recurrence is higher in the PG group than the TG (38.7% versus 24.4%). The anastomotic stenosis rate is also higher in the PG than the TG (27.4% versus 7.4%). Proximal gastrectomy is an option for upper third gastric cancer in terms of safety. However, it is associated with high risk of reflux symptoms and anastomotic stenosis. Therefore, TG should be the first choice for proximal gastric cancer to prevent reflux symptoms.

One of the most effective surgeries for sustainable weight loss in morbidly obese patients is laparoscopic sleeve gastrectomy (LSG). The present study aimed to assess the adherence of LSG patients with respect to following post-operative dietary requirements and micronutrient supplementation, as well as to investigate their perceived barriers in achieving optimal adherence. Retrospective data analysis was performed (3, 6, 9 and 12 months after LSG) using the medical records of 96 morbidly obese patients who had undergone LSG at our institution during 2011-2013. Data collected from patient records were: adherence to prescribed diet; adherence to prescribed consumption of fruit, vegetables, legumes and cereals; use of prescribed micronutrient supplements; and barriers to diet and micronutrient therapy adherence. Data were analysed using spss, version 14.0 (SPSS Inc., Chicago, IL, USA). At 3, 6, 9 and 12 months post-LSG, the rates of patient non-adherence to a prescribed diet were 39%, 45%, 51% and 74%, respectively. In particular, there was a low consumption of fruit, vegetables, legumes and cereals compared to the post-surgery prescription. In addition, the rates of patient non-adherence to prescribed micronutrient supplements at 3, 6, 9 and 12 months post-LSG were 43%, 51%, 59% and 67%, respectively. The main reasons for patient non-adherence to diet were poor self-discipline (72%) and poor family support (11%) whereas difficulty swallowing pills or capsules (61%) and cost (20%) were reported as the main barriers to post-LSG adherence. Morbidly obese patients who have undergone LSG do not follow exactly the post-operative dietary guidelines, including micronutrient therapy. © 2016 The British Dietetic Association Ltd.

With promising short-term results, laparoscopic sleeve gastrectomy (SG) has become the second most frequently performed bariatric procedure worldwide. Aside from a growing number of reports covering up to 10 years of follow-up, only limited data have been published so far on long-term results. The aim of the study was to present a 10-year follow-up for SG. University hospital setting, Austria. We present the first complete 10-year follow-up of 53 consecutive patients who underwent SG before 2006. In this multicenter study, weight loss success, weight regain, and revisional surgery were analyzed beside Bariatric Analysis and Reporting Outcome System (BAROS) scores. A mean maximum percent excess weight loss of 71±25% (percent total weight loss: 28±15%) was reached at a median of 12 (range 12-120) months after SG. At 10 years, a mean percent excess weight loss of 53±25% was achieved by 32 patients, corresponding to a percent total weight loss of 26.3±13.4%. Nineteen of the 53 patients (36%) were converted to Roux-en-Y gastric bypass (n = 18) or duodenal switch (n = 1) due to significant weight regain (n = 11), reflux (n = 6), or acute revision (n = 2) at a median of 36 months. Two patients died at 3 and 101 months postoperatively, unrelated to SG. A total of 31 patients (59%) suffered from weight regain of 10 kg or more, among them 24 patients (45%) with 15 kg or more, 16 patients (30%) with 20 kg or more, and 7 patients (13%) with 25 kg or more weight regain from nadir. Mean BAROS score was 2.4±2.2 at 10 years follow-up, classifying SG as "fairly efficient." Within a long-term follow-up of 10 years or more after SG, a high incidence of both significant weight regain and intractable reflux was observed, leading to conversion, most commonly to Roux-en-Y gastric bypass.

Esophagojejunostomy after laparoscopic total gastrectomy (LTG) is the most technically difficult type of anastomosis; thus, anastomotic complications such as leakage and stenosis sometimes occur. Identification of the safest anastomotic procedure is important for successful LTG. We have performed LTG since 2004 either with a circular stapler using an OrVil ™ anvil or via the overlap Orringer method with a linear stapler. This retrospective study aimed to determine which method results in a lower incidence of anastomotic complications in patients undergoing LTG. Data on 188 consecutive patients who underwent LTG between April 2004 and August 2016 were retrospectively reviewed. Patients were divided into those who underwent esophagojejunostomy performed via a circular stapler using an OrVil ™ anvil (group C, n = 49) or via the overlap method (group L, n = 139). Anastomotic complications occurred in five of 188 esophagojejunostomies (2.7%). They comprised three cases of leakage (1.6%), and two of stenosis (1.1%). There was no significant difference in patient characteristics or hematological variables between groups C and L. There was no significant difference between groups in operation time, blood loss, lymph node dissection, and intraoperative anastomotic problems. The rate of anastomotic complications was significantly lower in group L (0.7%, 1/139) than in group C (8.2%, 4/49; p = 0.005). In particular, anastomotic leakage in group L tended to be lower (0.7% 1/139) than in group C (4.1% 2/49), although this difference was not significant. The rate of anastomotic stenosis in group L was significantly lower (0%, 0/139) than in group C (4.1%, 2/49; p = 0.017). Furthermore multivariate analysis showed anastomotic procedure was an independent factor for anastomotic complication. There were fewer anastomotic complications after overlap esophagojejunostomy than after esophagojejunostomy via the OrVil ™ procedure, especially regarding anastomotic stenosis

Laparoscopic sleeve gastrectomy (LSG) is associated with serious complications, such as staple line (SL) leaks and bleeding. In order to prevent the occurrence of these complications, surgeons have advocated the need to strengthen the staple line. The aim of this randomized controlled study was to compare the efficacy of three different ways of strengthening of the SL in LSG in preventing surgical post-operative complications. Between April 2012 and December 2014, 600 patients (pts) scheduled for LSG were prospectively randomized into groups without SL reinforcement (group A) or with SL reinforcement including fibrin glue coverage (group B), or oversewn SL with imbricating absorbable (Monocryl™; group C) or barbed (V lock®) running suture (group D). Primary endpoints were post-operative leaks, bleeding, and stenosis, while secondary outcomes consisted of the time to perform the staple line reinforcement (SLR) and total operative time. Mean SLR operative time was lower for group B (3.4 ± 1.3 min) compared with that for groups C (26.8 ± 8.5 min) and D (21.1 ± 8.4 min) (p < 0.0001). Mean total operative time was 100.7 ± 16.4 min (group A), 104.4 ± 22.1 min (group B), 126.2 ± 18.9 min (group C), and 124.6 ± 22.8 (group D) (p < 0.0001). Post-operative leaks, bleeding, and stenosis were recorded in 14 pts (2.3 %), 5 pts (0.8 %), and 7 pts (1.1 %), respectively, without statistical difference between the groups. Our study suggests that SLR during LSG, with an imbricating or non-imbricating running suture or with fibrin glue, is an unrewarding surgical act with the sole effect of prolonging the operative time.

Placement of a bougie for sleeve sizing during laparoscopic sleeve gastrectomy (LSG) is recommended. We compared this standard with a suction calibration system (SCS) that performs all functions with one insertion, and measured each step's duration. Primary LSG was performed using a bougie and SCS in alternating order. Number of tube movements to achieve optimal placement, durations of decompression, leak testing, and overall operative time, and remnant linear measurements were obtained. LSG was performed in 26 patients (15 women, 11 men; mean age 36.8 years; mean BMI 45.3 kg/m(2)). The mean number of tube movements was significantly greater for the bougie than for the SCS (8.13 vs. 3.58; p < 0.0001). Percent reductions achieved using the SCS were: time to full decompression of the stomach, 62% (21 vs. 8 s; p < 0.138); tube placement, 51% (101 vs. 49 s; p < 0.0001); leak testing, 78% (119 vs. 26 s; p < 0.0003); and mean operative duration (from tube insertion to end of stapling), 21% (875 vs. 697 s; p < 0.019). Variance of the staple-line distance, measured from the greater curvature to the staple line, was 1.64 and 0.92 for the bougie and SCS, respectively, indicating a reduction in corkscrewing, for a 43.9% straighter sleeve. SCS maintained the gastric wall in place, thereby preventing corkscrewing, and reducing total operating time. Reducing the number of tube insertions may prevent esophageal damage and accidental tube stapling.

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.

ABSTRACT Background: Breast cancer is the most common malignant neoplasm in the female population. However, stomach is a rare site for metastasis, and can show up many years after initial diagnosis and treatment of the primary tumor. Aim: Analyze a case series of this tumor and propose measures that can diagnose it with more precocity. Methods: Were analyzed 12 patients with secondary gastric tumors. Immunohistochemistry has demonstrated that primary tumor was breast cancer. We retrieved information of age, histological type, interval between diagnosis of the primary breast cancer and its metastases, immunohistochemistry results, treatment and survival. Results: The mean age was 71.3 years (ranging 40-86). Ten cases had already been underwent mastectomy in the moment of the diagnosis of gastric metastasis. Two patients had diagnosis of both primary and secondary tumors concomitantly. At average, diagnosis of gastric metastasis was seven years after diagnosis of primary breast cancer (ranging 0-13). Besides, nine cases had also metastases in other organs, being bones the most affected ones. Immunohistochemistry of the metastases has shown positivity for CK7 antibody in 83.34%, estrogen receptor in 91.67%, progesterone receptor in 66.67% and AE1AE3 antibody in 75%, considering all 12 cases. Moreover, CK20 was absent significantly (66.67%). The positivity of BRST2 marker did not present statistical significance (41.67%). Eight cases were treated with chemotherapy associated or not with hormonal blockade. Surgical treatment of gastric metastasis was performed in four cases: three of them with total gastrectomy and one with distal gastrectomy. Follow-up has shown a mean survival of 14.58 months after diagnosis of metastasis, with only two patients still alive. Conclusion: Patients with a history of breast cancer presenting endoscopic diagnosis of gastric cancer it is necessary to consider the possibility of gastric metastasis of breast cancer. The confirmation is by

The indication and safety of concomitant cholecystectomy (CC) during bariatric surgical procedures are topics of controversy. Studies on the outcomes of CC with laparoscopic sleeve gastrectomy (LSG) are scarce. To assess the safety and 30-day surgical outcomes of CC with LSG. A retrospective analysis of the American College of Surgeons National Surgical Quality Improvement Program database 2010 to 2013. Univariate and multivariate analyses were used. Between 2010 and 2013, 21,137 patients underwent LSG; of those 422 (2.0%) underwent CC (LSG+CC), and the majority (20,715 [98%]) underwent LSG alone. Patients in both groups were similar in age, sex distribution, baseline weight, and body mass index. The average surgical time was significantly higher, by 33 minutes, in the LSG+CC cohort. No differences were noted between the groups with regard to overall 30-day mortality and length of hospital stay. CC increased the odds of any adverse event (5.7% versus 4.0%), but the difference did not reach statistical significance (odds ratio 1.49, P = .07). Two complications were noted to be significantly higher with LSG+CC, namely bleeding (P = .04) and pneumonia (P = .02). CC during LSG appears to be a safe procedure with slightly increased risk of bleeding and pneumonia compared with LSG alone. When factoring the potential risk and cost of further hospitalization for deferred cholecystectomy, these data support CC for established gallbladder disease.

Nutrition is a crucial factor in gastric resection surgery and the most suitable alimentary canal reconstruction method must be considered in order to reduce the risk of malnutrition. The cause of postgastrectomy malnutrition has not been clearly determined, but the mechanisms behind malnutrition are evidently multifactorial. To evaluate the nutritional status of patients who underwent different reconstructive procedures after total or subtotal gastrectomy. Fifty patients who have undergone gastrectomy for 0.5-39 years were assessed. The surgical procedures used were Billroth I in 7, Billroth II in 26, Henley in 3 and Roux-en-Y in 14 of the patients. Twenty one of them have followed gastrectomy for cancer. The nutritional status was evaluated by subjective global assessment, dietary recall and anthropometry. According to subjective global assessment, 6 of 50 patients were mild malnourished. The mean body mass index was 22 4.75 kg/m2, the average daily calorie intake was 1624 477 Kcal. Of the patients operated for cancer, those who underwent subtotal gastrectomy followed by Roux-en-Y presented higher body mass index. No relationship between the period of time since surgery with body mass index or with calorie intake was found. Among patients operated for cancer, subtotal gastrectomy with Roux-en-Y reconstruction is associated with better nutritional status. Factors other than low calorie intake are the cause of weight loss in patients with gastrectomy.

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

Epiphrenic diverticula (ED) are a rare clinical entity characterized by out-pouchings of the esophageal mucosa originating in the distal third of the esophagus, close to the diaphragm. The proportion of diverticula reported symptomatic enough to warrant surgery is extremely variable, ranging from 0% to 40%. The natural history of ED is still almost unknown and the most intriguing question concerns whether or not they all need surgical treatment. From 1993 to 2010 35 patients underwent surgery at our institution. Eleven patients were treated via a thoracotomic approach alone and were excluded from present study. The remaining 24 patients formed our study population. Seventeen patients (48.6%) underwent surgery via a purely laparoscopic approach, and received a diverticulectomy + myotomy + antireflux procedure. Seven patients (23%), with ED positioned well above inferior pulmonary vein, were treated via a combined laparoscopic-thoracotomic approach: they all underwent diverticulectomy + myotomy + an antireflux procedure. Mortality was nil. The overall morbidity rate was 25%. A suture leakage occurred in 4 patients (16.6%) and they were all conservatively treated. Patients' symptom scores decreased from a median of 15 to 0 (P = 0.0005). Laparoscopic surgery for ED is effective, but given the not negligible incidence of complications such suture-line leakage, should be considered only in symptomatic patients or in event of huge diverticula. A tailored combined laparoscopic-thoracotomic approach may be useful in case of ED located high in mediastinum or with large neck. Copyright © 2012 Elsevier Inc. All rights reserved.

"Reflux" gastritis after gastrectomy is associated with various symptoms that are often detrimental to the patients' quality of life. However, prevention of the reflux does not always bring relief from the symptoms of gastritis. Helicobacter pylori (H. pylori) is now considered one of the most important pathogenetic factors in gastritis. The association between H. pylori infection and reflux gastritis after gastrectomy was investigated in the present study. In total, 115 patients who had undergone gastrectomy were entered in this study. Five biopsy specimens from the gastric remnant were taken during upper GI endoscopy. One specimen was examined pathohistologically, and the remaining four were examined for H. pylori infection. The histological degree of gastritis was determined according to the score system of Rauws et al. Forty-six patients (40%) demonstrated H. pylori infection in their stomachs. The prevalence of the infection was significantly higher in patients with conventional gastrectomy than in those with subtotal gastrectomy. The prevalence of H. pylori infection was significantly lower in patients who had undergone gastrectomy more than 4 yr ago. The histological gastritis score in patients with H. pylori infection was significantly higher than in those without H. pylori infection. Furthermore, the eradication of H. pylori in patients with both serious gastritis symptoms and no bile reflux improved the symptoms and significantly decreased the histological gastritis score. The results suggest that H. pylori is a factor in the pathogenesis of reflux gastritis after gastrectomy.

Intra-corporeal esophagojejunostomy (EJ) using a linear stapler creates a stapler entry hole that requires secure closure during the totally laparoscopic total gastrectomy (TLTG) procedure for gastric cancer. Since a standard method has not been established yet, the feasibility of using V-loc 180 (Covidien, Mansfield, MA, USA) suture material was evaluated in this study. During January 2012 to March 2015, 25 patients who underwent linear stapling EJ and V-loc 180 closure of remaining enterotomy were included in this study. Basic clinico-pathological characteristics, surgical outcomes, and short-term complications were analyzed. The mean patient age was 60.4 ± 8.5 years. Nineteen males and six females were included in this study. The mean body mass index was 25.3 ± 2.3 kg/m 2 . There were 22 stage-I, 2 stage-II, and 1 stage-III gastric cancer patients. The mean operation time was 240.5 ± 44.6 min, and the time for anastomosis was 38.8 ± 11.2 min. The procedures were successfully performed in all cases without any intra-operative complications. There was one case of EJ leakage that occurred at the corner of EJ staple line and not at the enterotomy closure site. The closure of the remaining enterotomy site using V-loc 180 suture following linear stapler EJ is technically feasible and safe during the TLTG procedure. However, further experience and results from other surgeons are necessary to generalize this procedure.

Changes in fat-soluble vitamin levels after gastrectomy for gastric cancer.

Several authors have reported the relationship between gastric cancer risk and vitamins. However, there are few reports on fat-soluble vitamins after gastrectomy for gastric cancer. Fat malabsorption and suppression of food intake after gastrectomy for gastric cancer have been previously documented. Because of fat malabsorption and suppression of food intake, a potential deficiency in fat-soluble vitamins, such as vitamins A, D, E, and K, has been readily suggested. In about 20 % of patients, the serum vitamin E levels were decreased. Indeed, vitamin E deficiency is a common complication after gastrectomy. Continuous vitamin E deficiency could develop from neurological symptoms, i.e., peripheral neuropathy, limb or truncal ataxia. The total cholesterol level is associated with the vitamin E levels. However, the serum vitamin A levels were decreased in only 1.8 % of patients. In total gastrectomy cases, the serum vitamin A level may readily decrease. In contrast, 1,25(OH) 2 vitamin D deficiency, which is the most active vitamin D metabolite, is rare. Additionally, vitamin K deficiency after gastrectomy has not been reported thus far. Evidence that serum fat-soluble vitamin levels may decrease after gastrectomy for gastric cancer has not been established yet. Future research must explore fat-soluble vitamin deficiency after gastrectomy.

Weight loss is the sum of fat and lean mass loss. The aim of this study was to examine whether there are differences between 2 surgical procedures, laparoscopic sleeve gastrectomy (LSG) and laparoscopic Roux-en-Y gastric bypass (LRYGB), in terms of their effect on body composition and energy metabolism. In addition, the predictive value of preoperative body composition and energy metabolism on postoperative outcome was evaluated. All procedures were performed by the same surgeon (RP) at the St. Claraspital Basel in Switzerland. Calorimetry and DEXA were carried out at the same institution (Interdisciplinary Center of Nutritional and Metabolic Diseases, St. Claraspital Basel). Forty-two morbidly obese, mainly female (85%), nondiabetic and diabetic (50%) patients (body mass index [BMI]: 43.9 kg/m(2)±1.3) before and 17±5.6 months after LSG (n = 23) and LRYGB (n = 19) were examined. Body composition was analyzed by dual-energy X-ray absorptiometry (DEXA) and resting energy expenditure (REE); fat and carbohydrate oxidation was determined by indirect calorimetry. Follow-up was 100%. Excessive BMI loss (EBMIL) was 64.4% in the LSG group and 76.4% in the LRYGB group (P<.046). In both groups total fat and muscle mass decreased significantly compared with baseline (P<.001) and the percentage of muscle mass per kilogram of weight increased postoperatively (results not significant). REE decreased (P<.001) and REE per kilogram of weight increased significantly (P<.003) compared with baseline. Carbohydrate oxidation remained stable in both groups, and fat oxidation decreased significantly (P<.001) compared with baseline. In diabetic patients compared with nondiabetic patients there were no statistically significant differences in REE, substrate oxidation, or reduction in truncal fat. Postoperatively, lean mass was higher in diabetic patients (P = .037). Preoperative indirect calorimetry and DEXA results were of no predictive value for outcome. Changes in REE and body

Gastric leak is the most feared surgical postoperative complication after sleeve gastrectomy. An endoscopic procedure is usually required to treat the leak. No data are available on the cost-effectiveness of different stent types in this procedure. Between April 2005 and July 2016, patients with a confirmed gastric leak undergoing endoscopic treatment using a covered stent (CS) or double-pigtail stent (DPS) were included. The primary objective of the study was to assess overall costs of the stent types after primary sleeve gastrectomy. Secondary objectives were the cost-effectiveness of each stent type expressed as an incremental cost-effectiveness ratio (ICER); the incremental net benefit; the probability of efficiency, defined as the probability of being cost-effective at a threshold of €30 000, and identification of the key drivers of ICER derived from a multivariable analysis. One hundred and twelve patients were enrolled. The overall mean costs of gastric leak were €22 470; the mean(s.d.) cost was €24 916(12 212) in the CS arm and €20 024(3352) in the DPS arm (P = 0·018). DPS was more cost-effective than CS (ICER €4743 per endoscopic procedure avoided), with an incremental net benefit of €25 257 and a 27 per cent probability of efficiency. Key drivers of the ICER were the inpatient ward after diagnosis of gastric leak (surgery versus internal medicine), type of institution (private versus public) and duration of hospital stay per endoscopic procedure. DPS for the treatment of gastric leak is more cost-effective than CS and should be proposed as the standard regimen whenever possible. © 2018 BJS Society Ltd Published by John Wiley & Sons Ltd.

The present case study reported of amelanotic malignant melanoma of the esophagus. A 68-year-old man underwent laparoscopic distal gastrectomy for early gastric cancer diagnosis. After gastrectomy, endoscopic examination revealed a protruded lesion lying adjacent to the melanosis area of the esophagus. Histology of the biopsy specimen suggested malignancy, but the diagnosis could not be made. The patient underwent trans-thoraco-abdominal curative subtotal esophagectomy. Immunohistochemical examination of the resected specimen was negative for HBM-45 and Melan-A. However, immunohistochemical examinations of SOX10 (Sry-related HMg-Box gene 10) and KBA.62, which are not associated with melanosome, were strongly positive, and tyrosinase was notably positive. A diagnosis primary of amelanotic malignant melanoma of the esophagus that consisted of only premelanosomes was made. The present findings suggest that, in the diagnosis of malignant melanoma, SOX10 and KBA.62 may be useful, particularly in diagnosing amelanotic malignant melanoma.

To explore the feasibility, safety, and preliminary technical experience of single incision plus one port laparoscopic total gastrectomy combined with π-shaped esophagojejunal anastomosis (SILT-π) in the surgical treatment of gastric cancer. Clinical data of 5 gastric cancer patients undergoing SILT-π operation at the Department of General Surgery, The Second Affiliated Hospital of the Army Medical University from August to October 2017 were retrospectively analyzed. A 2.5-3.0 cm incision around the umbilicus was made for placing the gloveport as the passage for the lens, and the instruments of the surgeon and the assistant. Another operative port was placed in the left upper quadrant with a 12-mm Trocar for the passage of the energy device, the endoscopic cutting closure, as well as the postoperative drainage tube. A D2 lymph node (LNs) dissection was regularly conducted. After the abdominal esophagus was routinely mobilized, a side-to-side esophagus-jejunum anastomosis was made through a gastric pre-pulling esophagojejunal π-shaped anastomosis. The transection was then performed with a ligation on the cardia (or esophagus above the upper margin of the tumor) using a sterilized hemp rope in order to better expose the abdominal esophagus. Throughout the course of reconstruction, the ligature rope was held by the assistant to hold down the esophagus to allow easier esophagojejunal anastomosis. A hole was then made on the posterior wall of the esophagus, between 2 cm and 3 cm above the ligature rope, and another hole was made at the anti-mesenteric border of the jejunum 40 cm distal to the Treitz ligament. A side-to-side esophagojejunal π-shaped anastomosis was performed through two holes. An entry hole was formed after the anastomosis. After checking the anastomosis, this entry hole was closed through an intestinal mesenteric hole pre-made on its opposite side. The resected esophagus and stomach, together with the afferent loop jejunum, were simultaneously

Single port instrument delivery extended reach (SPIDER(®)) surgical system is a revolutionary surgical platform that allows triangulation of the surgical instruments while eliminating the crossing of instruments, the problematic characteristic of single access laparoscopic surgery. The purpose of this study was to analyze our initial experience with SPIDER(®) sleeve gastrectomy and to present the technical details of this new minimally invasive approach, performed in ten patients at the La Casamance Private Hospital between November 2012 and April 2013. All patients were reviewed at scheduled post-operative consultations at 1, 3 and 6 months. In addition to clinical examination, the post-operative consultation at one month also included a satisfaction survey using the Moorehead-Ardelt questionnaire. An initial series of ten sleeve gastrectomies were performed in female patients with a mean age of 41.5 years (range: 2-52). The mean BMI was 40.11 (range: 37.25-44.3). The intervention was performed through a single trocar in all patients with no "conversion" to classic laparoscopy or open surgery. The mean operative time was 61 ± 15.22 minutes (SD=standard deviation) (range: 43-96 min). The mean BMI at one month was 35.5 (SD:± 3.58, SEM: ± 1.13) (SEM=standard error of mean) with an average percentage of excess weight loss (%EWL) of 32.9% (SD:± 8.56%, SEM:± 2.71%). The mean BMI at three months was 32.4 (SD: ± 2.78, SEM: ± 0.88) with an average %EWL of 52.7% (SD: ± 8.64%, SEM: ± 2.73%). The mean BMI at six months was 29.9 (SD:± 2.60, SEM: ± 0.98) with a mean %EWL of 68.8% (SD: ± 8.38%, SEM:± 3.17%). Complete remission of co-morbid conditions was observed in four patients, improvement in three others, and no change in a single patient. The mean duration of hospitalization was 3.1 days. The mean follow-up period was 161 days (SD:± 57.4 days, range: 90-243 days). There was no mortality and no intra-operative and post-operative complications were noted. The

Laparoscopic myotomy: technique and efficacy in treating achalasia.

PubMed

Ali, A; Pellegrini, C A

2001-04-01

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

The life-time drinking profiles of Japanese alcoholics have shown that gastrectomy increases susceptibility to alcoholism. We investigated the trends in gastrectomy and alcohol dehydrogenase-1B (ADH1B) and aldehyde dehydrogenase-2 (ALDH2) genotypes and their interactions in alcoholics. This survey was conducted on 4879 Japanese alcoholic men 40 years of age or older who underwent routine gastrointestinal endoscopic screening during the period 1996-2010. ADH1B/ALDH2 genotyping was performed in 3702 patients. A history of gastrectomy was found in 508 (10.4%) patients. The reason for the gastrectomy was peptic ulcer in 317 patients and gastric cancer in 187 patients. The frequency of gastrectomy had gradually decreased from 13.3% in 1996-2000 to 10.5% in 2001-2005 and to 7.8% in 2006-2010 (P < 0.0001). ADH1B*1/*1 was less frequent in the gastrectomy group than in the non-gastrectomy group (age-adjusted prevalence: 20.4 vs. 27.6%, P = 0.006). ALDH2 genotype distribution did not differ between the two groups. The frequency of inactive ALDH2*1/*2 heterozygotes increased slightly from 13.0% in 1996-2000 to 14.0% in 2001-2005 and to 15.4% in 2006-2010 (P < 0.08). Two alcoholism-susceptibility genotypes, ADH1B*1/*1 and ALDH2*1/*1, modestly but significantly tended not to occur in the same individual (P = 0.026). The frequency of ADH1B*1/*1 decreased with ascending age groups. The high frequency of history of gastrectomy suggested that gastrectomy is still a risk factor for alcoholism, although the percentage decreased during the period. The alcoholism-susceptibility genotype ADH1B*1/*1 was less frequent in the gastrectomy group, suggesting a competitive gene-gastrectomy interaction for alcoholism. A gene-gene interaction and gene-age interactions regarding the ADH1B genotype were observed.

Endoscopic management of leaks/fistulas after laparoscopic sleeve gastrectomy (LSG) is gaining popularity in the bariatric surgery. This study aimed to review the efficacy and safety of over-the-scope-clip (OTSC) system in endoscopic closure of post-LSG leak/fistula. PubMed/Medline and major journals of the field were systematically reviewed for studies on endoscopic closure of post-LSG leaks/fistula by means of the OTSC system. A total of ten eligible studies including 195 patients with post-LSG leaks/fistula were identified. The time between LSG and leak/fistula ranged from 1 day to 803 days. Most of the leaks/fistula were located at the proximal staple line, and they sized from 3 to 20 mm. Time between leak diagnosis and OTSC clipping ranged from 0 to 271 days. Thirty-three out of 53 patients (63.5%) required one clip for closure of the lesion. Regarding the OTSC-related complications, a leak occurred in five patients (9.3%) and OTSC migration, stenosis, and tear each in one patient (1.8%). Of the 73 patients with post-LSG leak treated with OTSC, 63 patients had an overall successful closure (86.3%). OTSC system is a promising endoscopic approach for management of post-LSG leaks in appropriately selected patients. Unfortunately, most studies are series with a small sample size, short-term follow-up, and mixed data of concomitant procedures with OTSC. Further studies should distinguish the net efficacy of the OTSC system from other concomitant procedures in treatment of post-LSG leak.

To study weight loss and growth after laparoscopic sleeve gastrectomy (LSG) in pediatric patients with PWS compared with those without the syndrome. Academic center with a standardized care pathway for pediatric bariatric surgery as a part of a prospective clinical outcome study on children and adolescents undergoing weight loss surgery. Clinical data of all PWS patients who underwent LSG were abstracted from our prospective database, which included all pediatric patients who underwent bariatric surgery. These data were then compared with a 1:3 non-PWS group matched for age, gender, and body mass index (BMI). Data for up to 5 years follow-up were analyzed. The 24 PWS patients (mean age 10.7; 6<8 yr old, range 4.9-18) had a preoperative BMI of 46.2 ± 12.2 kg/m(2). All PWS patients had obstructive sleep apnea (OSA), 62% had dyslipidemia, 43% had hypertension, and 29% had diabetes mellitus. BMI change at the first, second, third, fourth, and fifth annual visits was -14.7 (n = 22 patients), -15.0 (n = 18), 12.2 (n = 13), -12.7 (n = 11), and -10.7 (n = 7), respectively, in the PWS group, whereas the non-PWS group had a BMI change of -15.9 (n = 67), -18.0 (n = 50), -18.4 (n = 47), -18.9 (n = 26), and -19.0 (n = 20), respectively. No significant difference was observed in postoperative BMI change (P = .2-.7) or growth (postoperative height z-score P value at each annual visit = .2-.8); 95% of co-morbidities in both groups were in remission or improved, with no significant difference in the rate of co-morbidity resolution after surgery (P = .73). One PWS patient was readmitted 5 years after surgery with recurrence of OSA and heart failure. No other readmissions occurred, and there were no reoperations, postoperative leaks, or other complications. No mortality or major morbidity was observed during the 5 years of follow-up.

Robotic-assisted general and bariatric surgery is gaining popularity among surgeons. The aim of this study was to analyze the utilization and outcome of laparoscopic versus robotic-assisted laparoscopic techniques for common elective general and bariatric surgical procedures performed at Academic Medical Centers. We analyzed data from University HealthSystem Consortium clinical database from October 2010 to February 2014 for all patients who underwent laparoscopic versus robotic techniques for eight common elective general and bariatric surgical procedures: gastric bypass, sleeve gastrectomy, gastric band, antireflux surgery, Heller myotomy (HM), cholecystectomy (LC), colectomy, rectal resection (RR). Utilization and outcome measures including demographics, in-hospital mortality, major complications, 30-day readmission, length of stay (LOS), and costs were compared between techniques. 96,694 laparoscopic and robotic procedures were analyzed. Utilization of the robotic approach was the highest for RR (21.4%), followed by HM (9.1%). There was no significant difference in in-hospital mortality or major complications between laparoscopic versus robotic techniques for all procedures. Only two procedures had improved outcome associated with the robotic approach: robotic HM and robotic LC had a shorter LOS compared to the laparoscopic approach (2.8 ± 3.6 vs. 2.3 ± 2.1; respectively, p < 0.05 for HM and 2.9 ± 2.4 vs. 2.3 ± 1.7; respectively, p < 0.05 for LC). Costs were significantly higher (21%) in the robotic group for all procedures. A subset analysis of patients with minor/moderate severity of illness showed similar results. This national analysis of academic centers showed a low utilization of robotic-assisted laparoscopic elective general and bariatric surgical procedures with the highest utilization for rectal resection. Compared to conventional laparoscopy, there were no observed clinical benefits associated with the robotic approach, but there was a

Aim of the study was to evaluate nutritional status in patients after gastrectomy due to gastric cancer. In 55 (26 males and 29 females) gastric cancer patients after gastrectomy body composition (bioimpedansometry method); resting energy expenditures and home actual nutrition (frequency analysis method) were evaluated. Blood levels of major nutrients and metabolites were assessed. Both men and women suffered from weight loss after gastrectomy (mean BMI was 19,8+/-4,7 kg/m2 in men and 20,5+/-1,9 in women). Higher BMI was positively correlated with age in women (R=0,45; p<0,03), but not in men, however there was no difference in mean age and mean time after gastrectomy between men and women. Mean body fat mass significantly decreased in men (7,4+/-5,0 kg) and in women (12,0+/-7,1 kg) in compare to normal values (18,2 and 22,5 correspondingly) (p<0,001). Resting energy expenditure variably decreased (for 13-53%) in half of the patients, mainly due to decrease in lipid oxidation rate. Mean daily energy intake was lower than normal in short-term (1359 kcal in period of 12 months) and long-term (1814 kcal in 1-5 years period) after gastrectomy, due to decrease consumption of proteins, carbohydrates and fat. Mean blood total protein, hemoglobin and hematocrit levels were lower than normal values in 40% of patients. In gastric cancer patients low BMI, low fat mass and energy consumption are observed even long period of time after gastrectomy. Dietary counseling and support are badly needed in patients short-term as well as long-term period after gastrectomy in men and younger women.

Sleeve gastrectomy and gastro-oesophageal reflux disease: a complex relationship.

2013-07-01

Sleeve gastrectomy is rapidly becoming popular as a standalone bariatric operation. At the same time, there are valid concerns regarding its long-term durability and postoperative gastro-oesophageal reflux disease. Though gastric bypass remains the gold standard bariatric operation, it is not suitable for all patients. Sleeve gastrectomy is sometimes the only viable option. Patients with inflammatory bowel disease, liver cirrhosis, significant intra-abdominal adhesions involving small bowel and those reluctant to undergo gastric bypass could fall in this category. It is widely recognised that some patients report worsening of their gastro-oesophageal reflux disease after sleeve gastrectomy. Still, others develop de novo reflux. This review examines if it is possible to identify these patients prior to surgery and thus prevent postoperative gastro-oesophageal reflux disease after sleeve gastrectomy.

The effect of laparoscopic sleeve gastrectomy (LSG) on gastroesophageal reflux disease (GERD) is controversial. Although concomitant hiatal hernia repair (HHR) at the time of LSG is common and advocated by many, there are few data on the outcomes of GERD symptoms in these patients. The aim of this study was to evaluate the effect of concomitant HHR on GERD symptoms in morbidly obese patients undergoing LSG. A single institution, multi-surgeon, prospectively maintained database was examined to identify patients who underwent LSG and concomitant HHR from December 2010 to October 2013. Patient characteristics, operative details, and postoperative outcomes were analyzed. Standardized patient questionnaires administered both pre- and postoperatively were utilized. Primary endpoints included subjective reflux symptoms and the need for antisecretory therapy. Weight loss was considered a secondary endpoint. Fifty-eight patients were identified meeting inclusion criteria (LSG + HHR), with a mean follow-up of 97.5 weeks (range 44-172 weeks). The mean age of the cohort was 49.5 ± 11.2 years, with 74.1 % being female. Mean preoperative BMI was 44.2 ± 6.6 kg/m(2). Preoperative upper gastrointestinal contrast series was performed in all patients and demonstrated a hiatal hernia in 34.5 % of patients and reflux in 15.5 % of patients. Preoperatively, 44.8 % (n = 26) of patients reported subjective symptoms of reflux and/or required daily antisecretory therapy [Corrected]. After LSG + HHR, 34.6 % of symptomatic patients had resolution of their symptoms off therapy while the rest remained symptomatic and required daily antisecretory therapy; 84.4 % of patients that were asymptomatic preoperatively remained asymptomatic after surgery. New onset reflux symptoms requiring daily antisecretory therapy was seen in 15.6 % of patients who were previously asymptomatic. Post surgical weight loss did not correlate with the presence or resolution of reflux symptoms. Based

Preserving gastric function and improving quality of life (QOL) is the tendency of surgery for early gastric cancer. Function preserving gastrectomy (FPG) is applied to modify the extent of surgery and to achieve better quality of life at the premise of radical resection. Pylorus-preserving gastrectomy is the most favorable approach of FPG with oncological safety, which can improve nutritional status and QOL via preserving pylorus and vagal nerve. Proximal gastrectomy is widely accepted as FPG for early upper 1/3 gastric cancer. However, the most optimal way of anastomosis is not yet solved. Sentinel node navigation is currently the most accurate approach for intraoperative diagnosis of lymph node metastasis, which stimulates the development of many kinds of FPG procedures for individual treatment. Nevertheless, more efforts should be made to reduce false negative rate of sentinel node biopsy. Herein we discuss the valuation and prospect of FPG.

Surgical treatment of distal rectal cancer has long been based only on abdominoperineal excision, resulting in a permanent stoma and not always offering a definitive local control. Sphincter saving surgery has emerged in the last 20 years and can be offered also to patients with low lying tumours, provided that the external sphincter is not involved by the disease. An intersphincteric resection (ISR) is based on the resection of the rectum with a distal dissection proceeding into the space between the internal and the external anal sphincter. Originally described as an open procedure, it has also been developed with the laparoscopic approach, and also this technically demanding procedure is inscribed among those offered to the patient by a minimally invasive surgery. Indications have to be strict and patient selection is crucial to obtain both oncological and functional optimal results. The level of distal dissection and the extent of internal sphincter resected are chosen according to the distal margin of the tumour and is based on MRI findings: accurate imaging is therefore mandatory to better define the surgical approach. We here present our actual indications for ISR, results in terms of operative time, median hospital stay for ISR in our experience and review the updated literature.

Type 2 diabetes mellitus (T2DM) and obesity are often associated in the same metabolic pathology and represent a significant public health problem. Although laparoscopic sleeve gastrectomy (LSG) is a relatively recent technique of bariatric surgery, it has shown to be efficient and safe and has obtained much support from physicians and patients. Several studies have highlighted the effects in terms of resolution and improvement of diabetes. From January 2009 to November 2012, 15 patients in Obesity Class II (body mass index [BMI], 37.9 ± 1.5 kg/m(2); baseline weight, 102.7 ± 11.6 kg) with uncontrolled T2DM despite taking a glucose-lowering drug therapy (glycated hemoglobin [HbA1c], 8.1 ± 0.6%) underwent LSG and advanced practice medical management in accordance with the American Diabetes Association guidelines. All patients were subjected to follow-up controls with anthropometric and metabolic indices at 5, 15, 30, and 60 days, and at 6 and 12 months after surgery, remission of diabetes was also evaluated. At 1 year after surgery, the mean excess weight loss percentage (EWL%) was 58.4%, and the mean BMI had decreased from the preoperative value of 37.9 kg/m(2) to 30.4 kg/m(2). The average reduction in HbA1c was 2.5 (30.9%). The mean homeostatic model assessment of insulin resistance decreased from 13.3 to 4.9. Overall, during the period of observation, four patients (26.7%) had started drug therapy again, six patients had complete remission (40%), and five patients had partial remission (33.3%). LSG not only makes it possible to attain a significant EWL% in obese patients, but also a remission or improvement of diabetes. Further studies are required to determine the duration of the effect and the role of different factors involved.

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

Perioperative complications can affect outcomes after gastrectomy for cancer, with high mortality and morbidity rates ranging between 10 and 40%. The absence of a standardized system for recording complications generates wide variation in evaluating their impacts on outcomes and hinders proposals of quality-improvement projects. The aim of this study was to provide a list of defined gastrectomy complications approved through international consensus. The Gastrectomy Complications Consensus Group consists of 34 European gastric cancer experts who are members of the International Gastric Cancer Association. A group meeting established the work plan for study implementation through Delphi surveys. A consensus was reached regarding a set of standardized methods to define gastrectomy complications. A standardized list of 27 defined complications (grouped into 3 intraoperative, 14 postoperative general, and 10 postoperative surgical complications) was created to provide a simple but accurate template for recording individual gastrectomy complications. A consensus was reached for both the list of complications that should be considered major adverse events after gastrectomy for cancer and their specific definitions. The study group also agreed that an assessment of each surgical case should be completed at patient discharge and 90 days postoperatively using a Complication Recording Sheet. The list of defined complications (soon to be validated in an international multicenter study) and the ongoing development of an electronic datasheet app to record them provide the basic infrastructure to reach the ultimate goals of standardized international data collection, establishment of benchmark results, and fostering of quality-improvement projects.

To investigate the effects and mechanism of postoperative insulin resistance in gastrectomy patients with preoperative oral carbohydrate. From April to October 2011, 60 consecutive gastric cancer patients met inclusion criteria were divided into oral carbohydrate group and placebo group by randomized double-blind principles. Resting energy expenditure (REE), fasting blood glucose, insulin and triglyceride level were detected in 4 hours preoperatively. The 500 ml carbohydrate or placebo were administrated orally 2-3 hours before anaesthesia. Two group patients underwent radical distal subtotal gastrectomy under epidural compounded intravenous anesthesia. After laparotomy and before the abdomen was closed, a piece of rectus abdominis was taken and fixed in 3% glutaraldehyde. REE, fasting blood glucose, insulin and triglyceride level were detected immediately after surgery. The changes of insulin resistance index, blood triglycerides level, REE and respiratory quotient were compared pre- and post-operatively. The changes of rectus abdominis mitochondrial ultrastructure were observed by transmission electron microscopy respectively. There were 48 patients (34 males and 14 females) completed the trial. The 24 and 24 patients in oral placebo and carbohydrate groups respectively. In oral placebo group, post-operative insulin resistance index, REE, respiratory quotient, serum triglyceride level and the rectus abdominis mitochondrial damage index were 12.68 ± 3.13, (1458 ± 169) kcal/d, 0.73 ± 0.42, (0.53 ± 0.24) g/L and 1.14 ± 0.33, respectively. And the above items were 5.67 ± 1.40, (1341 ± 110) kcal/d, 0.79 ± 0.22, (1.04 ± 0.97) g/L and 0.92 ± 0.19 in oral carbohydrate groups respectively. All difference was statistically significant (t = 6.646, 2.851, 6.546, 2.542 and 2.730, all P < 0.05).

Laparoscopic treatment of lesions of the distal pancreas has gained favour worldwide in the last decade. The objective of this study was to analyze 3 cases of insulinoma successfully treated with the laparoscopic approach. From 2000 to 2007 in our institution 3 patients with insulinoma of the left pancreas were treated with a laparoscopic approach. The insulinoma was diagnosed by helical CT scan, Two cases were treated by left pancreatectomy and one by enucleation. The resections were achieved by laparoscopy with no conversion to laparotomy. There were no intraoperative complications. Average blood loss was 180 mi (range: 150-350). Mean operative time was 232 minutes (range: 225-240). Morbidity consisted in one mild pancreatic fistula after left pancreatectomy that was healed by conservative treatment after 24 days. The mean hospital stay was 13 days (range: 10-20). During the follow-up insulinoma symptoms have disappeared in all patients. This study confirms the feasibility of laparoscopic resection for insulinoma. Operative times were quite acceptable and the conversion rate was nil. Times to oral intake and walking were shorter than after open surgery, as was the mean postoperative hospital stay.

The most popular scale to stratify the postoperative risk is the Obesity Surgery Mortality Risk Score (OS-MRS). The design and ease of interpretation make the scale a potential tool for clinical use. To evaluate the usefulness of the OS-MRS scale in the enrollment of patients for laparoscopic bariatric procedures, including laparoscopic sleeve gastrectomy (LSG) and laparoscopic Roux-en-Y gastric bypass (LRYGB). The medical records of patients who underwent LSG or LRYGB due to obesity between January 2010 and December 2010 were reviewed retrospectively. The decision of choosing the surgical procedure was made on the basis of OS-MRS risk category. The primary endpoint of this study was the 90-day mortality, and the secondary endpoint was the presence of major complications. There were 107 patients including 66 women and 41 men. The OS-MRS classes were A (48%), B (47%) and C (5%). The LSG was applied to patients with higher body mass index and to patients of class C. The secondary endpoints occurred in 6 patients, distributed in 10% of class A, 2% of class B and 0% of class C patients (p < 0.05). In 5 of 6 cases the endpoint was observed after LRYGB. Fatal cases were not observed. The OS-MRS can be a useful clinical tool for choosing the appropriate laparoscopic bariatric procedure, depending on the risk of postoperative complications. Low risk of postoperative complications should not lower the watchfulness of the surgeon.

Distal advanced gastric cancer (AGC) occasionally causes gastric outlet obstruction (GOO). We developed a laparoscopic stomach-partitioning gastrojejunostomy (LSPGJ) to restore the ability of food intake. This was a retrospective study performed at a single institution. Of consecutive 78 patients with GOO caused by AGC between 2006 and 2012, 43 patients who underwent LSPGJ were enrolled. The procedure was performed in an antiperistaltic Billroth II fashion, and the afferent loop was elevated and fixed along the staple line of the proximal partitioned stomach. Then, patients for whom R0 resection was planned received chemotherapy prior to laparoscopic gastrectomy. The primary end point was food intake at the time of discharge, which was evaluated using the GOO scoring system (GOOSS). Short- and long-term outcomes were assessed as secondary end points. Overall survival was estimated and compared between the groups who received neoadjuvant chemotherapy followed by surgery (NAC group), definitive chemotherapy followed by curative resection (Conversion group), and best supportive care (BSC group). The median operative time was 92 min, blood loss did not exceed 30 g in any patient, and postoperative complications (Clavien-Dindo grade ≥2) were only seen in four patients (9.3 %). The median time to food intake was 3 days, and GOOSS scores were significantly improved in 41 patients (95.3 %). Chemotherapy was administered to 38 patients (88.4 %), of whom 11 later underwent radical resection, and 4 of 11 patients underwent conversion surgery following definitive chemotherapy. Median survival times were significantly superior in the NAC (n = 7; 46.8 months) and Conversion (n = 4; 35.9 months) groups than in the BSC group (n = 26; 12.2 months); however, the difference was not significant between the Conversion and NAC groups. LSPGJ is a feasible and safe minimally invasive induction surgery for patients with GOO from surgical and oncological perspectives.

Laparoscopic repair of indirect inguinal hernia in children: does partial resection of the sac make any impact on outcome?

To test the hypothesis that during laparoscopic hernia repair, partial resection of the distal sac along with suture ligation of the neck is better than simple transection and ligation. The following two techniques of laparoscopic hernia repair were compared: Group I, circumferential incision of peritoneum at the deep ring and partial resection of the distal sac and suture ligation at the neck; versus Group II, circumferential incision of the peritoneum at the deep ring and suture ligation at the neck. Twenty-five cases of inguinal hernia were randomly selected in each group between the age group of 6 months to 12 years. The outcome measures were recurrence, intra- or postoperative complications, and time taken for surgery. There were no recurrences in either group. Other parameters for comparison were also not statistically different between the two groups. There was no conversion. Although partial resection of the sac has been an essential step in open hernia repair over five decades, its value has been questioned by our study, because omitting this step during laparoscopic repair has not adversely affected the outcomes. Partial resection of the sac is not a necessary component of hernia repair. It is a technical necessity of the open approach. Therefore, omitting this step in laparoscopic repair does not adversely affect the outcome.

In recent years, increasingly sophisticated tools have allowed for more complex robotic surgery. Robotic gastrectomy, however, is adopted in only a few selected centers. The goals of this study were to examine the adoption of robotic gastrectomy and to compare outcomes between open and robotic gastric resections. This is a case-matched analysis of patients who underwent robotic and open gastric resection performed at Sanchinarro University Hospital, Madrid from November 2011 to February 2017. Patient data were obtained retrospectively. Clinicopathologic characteristics and perioperative and postoperative outcomes were recorded and analyzed. Two groups of demographically similar patients were analyzed: the robotic group (n = 20) and the open surgery group (n = 19). The patient characteristics of the two groups have been compared. Robotic resection resulted in less blood loss, shorter postoperative hospital stay, and a longer operating time. The two groups had similar complication rates. Pathological data were similar for both procedures. Robotic gastrectomy for locally advanced gastric carcinoma is safe, and long-term outcomes are comparable to those patients who underwent open resection. Robotic gastrectomy resulted in a shorter hospital stay, less blood loss and morbidity comparable with the outcomes of open gastrectomy.

Gastrectomy for gastric cancer is a significant cause of secondary exocrine pancreatic insufficiency. Pancreatic enzyme replacement therapy may influence nutritional status and quality of life after gastrectomy, but the pertinent clinical research to date remains controversial. A randomized controlled trial to test this hypothesis was carried out. After gastrectomy, 43 patients with gastric cancer were randomly assigned to a normal diet (Normal-d; n = 21) or to a pancreatic enzyme supplementation diet (PES-d; n = 22) and were followed up during a 12-month period, assessing nutritional status and quality of life through body mass index (BMI), instant nutritional assessment (INA) class status, serum pre-albumin (SPA) values, and GastroiIntestinal Quality of Life Index (GIQLI). BMI was not significantly influenced by the type of diet; INA class status was significantly improved in the PES-d arm, particularly during the first 3 months after gastrectomy; SPA levels increased in both arms at 6 months after gastrectomy, reaching significantly higher values in the PES-d arm at 12 months. GIQLI was not significantly influenced by the type of diet throughout the follow-up period; however, this index significantly improved in the PES-d arm between the first and third month after gastrectomy. PES-d improves nutritional status and quality of life after gastrectomy for gastric cancer, particularly within 3 months from the operation. A larger, multicenter trial is necessary to address the potential influence of several confounding variables such as disease stage and adjuvant treatments.

Experience with laparoscopic resection of pancreatic neoplasms remains limited. The purpose of this study is to critically analyze the indications for and outcomes after laparoscopic resection of pancreatic neoplasms. The medical records of all patients undergoing laparoscopic resection of pancreatic neoplasms from July 2000 to February 2006 were reviewed. Data are expressed as mean +/- standard deviation. Laparoscopic pancreatic resection was performed in 22 patients (M:F, 8:14) with a mean age of 56.3 +/- 15.1 years and mean body mass index (BMI) of 26.3 +/- 4.5 kg/m2. Nine patients had undergone previous intra-abdominal surgery. Indications for pancreatic resection were cyst (1), glucagonoma (1), gastrinoma (2), insulinoma (3), metastatic tumor (2), IPMT (4), nonfunctioning neuroendocrine tumor (3), and mucinous/serous cystadenoma (6). Mean tumor size was 2.4 +/- 1.6 cm. Laparoscopic distal pancreatectomy was attempted in 18 patients and completed in 17, and enucleation was performed in 4 patients. Laparoscopic ultrasound (n = 10) and a hand-assisted technique (n = 4) were utilized selectively. Mean operative time was 236 +/- 60 min and mean blood loss was 244 +/- 516 ml. There was one conversion to an open procedure because of bleeding from the splenic vein. The mean postoperative LOS was 4.5 +/- 2.0 days. Seven patients experienced a total of ten postoperative complications, including a urinary tract infection (UTI) (1), lower-extremity deep venous thrombosis (DVT) and pulmonary embolus (1), infected peripancreatic fluid collection (1), pancreatic pseudocyst (1), and pancreatic fistula (6). Five pancreatic fistulas were managed by percutaneous drainage. The reoperation rate was 4.5% and the overall pancreatic-related complication rate was 36.4%. One patient developed pancreatitis and a pseudocyst 5 months postoperatively, which was managed successfully with a pancreatic duct stent. There was no 30-day mortality. Laparoscopic pancreatic resection is safe and

Double-J stent insertion has been generally performed during laparoscopic upper urinary tract (UUT) surgical procedures to prevent transient urinary tract obstruction and postoperative flank pain from ureteral edema and blood clots. Several restrictive conditions that make this procedure difficult and time consuming, however, include the coiled distal ends of the flexible Double-J stent and the limited bending angle of the laparoscopic instruments. To overcome these limitations, we devised a Double-J stent insertion method using the new J-tube technique. Between July 2011 and May 2013, Double-J stents were inserted using the J-tube technique in 33 patients who underwent a laparoscopic UUT surgical procedure by a single surgeon. The mean stent placement time was 4.8±2.7 minutes, and there were no intraoperative complications. In conclusion, the J-tube technique is a safe and time-saving method for Double-J stent insertion during laparoscopic surgical procedures.

To identify which technique is better for avoiding biliary reflux and gastritis between uncut Roux-en-Y and Billroth II reconstruction. A total of 158 patients who underwent laparoscopy-assisted distal gastrectomy for gastric cancer at the First Hospital of Jilin University (Changchun, China) between February 2015 and February 2016 were randomized into two groups: uncut Roux-en-Y (group U) and Billroth II group (group B). Postoperative complications and relevant clinical data were compared between the two groups. According to the randomization table, each group included 79 patients. There was no significant difference in postoperative complications between groups U and B (7.6% vs 10.1%, P = 0.576). During the postoperative period, group U stomach pH values were lower than 7 and group B pH values were higher than 7. After 1 year of follow-up, group B presented a higher incidence of biliary reflux and alkaline gastritis. However, histopathology did not show a significant difference in gastritis diagnosis ( P = 0.278), and the amount of residual food and gain of weight between the groups were also not significantly different. At 3 mo there was no evidence of partial recanalization of uncut staple line, but at 1 year the incidence was 13%. Compared with Billroth II reconstruction, uncut Roux-en-Y reconstruction is secure and feasible, and can effectively reduce the incidence of alkaline reflux, residual gastritis, and heartburn. Despite the incidence of recanalization, uncut Roux-en-Y should be widely applied.

Iatrogenic injury of the intrathoracic oesophagus with bougie during sleeve gastrectomy

One of the most popular procedures amongst obesity surgery is the sleeve gastrectomy. There is international consensus regarding the usage of bougie for sleeve gastrectomy calibration. Nevertheless, there is a dissociation between the number of oesophageal perforations reported for any other oesophageal/gastric operation that requires bougie (e.g., anti-reflux surgery, incidence 1.2%) and bariatric surgery, where this complication seems to be almost a myth. Interestingly enough, the number of bariatric procedures is much higher than any other oesophageal/gastric surgery. This suggests that oesophageal perforations in obesity surgery are underreported. We report a case of injury of the intrathoracic oesophagus with bougie that occurred during a sleeve gastrectomy. In the infrequent case that the perforation is diagnosed during surgery, primary repair during the same intervention is highly recommended. Videothoracoscopy might be an effective option in case of necessity. We were able to complete the sleeve gastrectomy without increasing morbidity. PMID:28695879

Little has been known about the contractile characteristics of diabetic stomach. We investigated spontaneous contractions and responses to acetylcholine in the gastric muscle in diabetic patients and non-diabetic control subjects according to the region of stomach. Gastric specimens were obtained from 26 diabetics and 55 controls who underwent gastrectomy at Samsung Medical Center between February 2008 and November 2011. Isometric force measurements were performed using circular muscle strips from the different regions of stomach under basal condition and in response to acetylcholine. Basal tone of control was higher in the proximal stomach than in the distal (0.63 g vs 0.46 g, p = 0.027). However, in diabetics, basal tone was not significantly different between the proximal and distal stomach (0.75 g vs 0.62 g, p = 0.32). The distal stomach of diabetics had higher basal tone and lower frequency than that of control (0.62 g vs 0.46 g, p = 0.049 and 4.0/min vs 4.9/min, p = 0.049, respectively). After exposure to acetylcholine, dose-dependent increases of basal tone, peak, and area under the curve (AUC) were noticed in both proximal and distal stomach of the two groups. In the proximal stomach, however, the dose-dependent increase of basal tone and AUC was less prominent in diabetics than in control. On the contrary to control, the proximal to distal tonic gradient was not observed in diabetic stomach. Diabetic stomach also had lower frequency of spontaneous contraction in the distal stomach and less acetylcholine-induced positive inotropic effect in the proximal stomach than control. © 2013 John Wiley & Sons Ltd.

To illustrate how decision modeling may identify relevant uncertainty and can preclude or identify areas of future research in surgery. To optimize use of research resources, a tool is needed that assists in identifying relevant uncertainties and the added value of reducing these uncertainties. The clinical pathway for laparoscopic distal pancreatectomy (LDP) versus open (ODP) for nonmalignant lesions was modeled in a decision tree. Cost-effectiveness based on complications, hospital stay, costs, quality of life, and survival was analyzed. The effect of existing uncertainty on the cost-effectiveness was addressed, as well as the expected value of eliminating uncertainties. Based on 29 nonrandomized studies (3.701 patients) the model shows that LDP is more cost-effective compared with ODP. Scenarios in which LDP does not outperform ODP for cost-effectiveness seem unrealistic, e.g., a 30-day mortality rate of 1.79 times higher after LDP as compared with ODP, conversion in 62.2%, surgically repair of incisional hernias in 21% after LDP, or an average 2.3 days longer hospital stay after LDP than after ODP. Taking all uncertainty into account, LDP remained more cost-effective. Minimizing these uncertainties did not change the outcome. The results show how decision analytical modeling can help to identify relevant uncertainty and guide decisions for future research in surgery. Based on the current available evidence, a randomized clinical trial on complications, hospital stay, costs, quality of life, and survival is highly unlikely to change the conclusion that LDP is more cost-effective than ODP.

Needlescopic sleeve gastrectomy: pushing the boundaries of the standard technique.

Laparoscopic sleeve gastrectomy (LSG) is the most common bariatric surgery performed worldwide. Improvements in LSG have been suggested to achieve better weight loss or to lessen the complications rates. We propose a change in the standard technique to privilege the use of thinner instruments, the needlescopic sleeve gastrectomy (NSG). A 40-year-old female, BMI 40, with no previous abdominal surgery was selected for a NSG. She was placed in a semi-sitting position with the surgeon standing between the legs. Pneumoperitoneum was created through open laparoscopy; 5 trocars were inserted in standard position for laparoscopic gastric surgery. We have used one 12 mm trocar in the navel for a 5 mm scope and for stapling the stomach; one 5 mm trocar for impedance coagulator and also for the scope during the stapling process, and three 3 mm trocars for liver retraction, left hand manipulation, and greater curve exposition. Surgical techniques are basically the same as for a standard LSG until the moment of stapling the stomach, when the 5 mm scope is changed to the right hand trocar. Stapling can be done trough the umbilical port, parallel to the lesser curvature, in contact with the calibration tube. After stapling, hemostasis was achieved by bipolar coagulation, application of titanium clips, and absorbable suture. The 12 mm umbilical orifice is closed after extraction of the resected stomach. Operative time was 76 min. There was no per-operative complication. Recovery was uneventful and patient was discharged at post operative day 2. Pain was considered minor by the patient. One month after surgery, cosmetic results were very convincing. There are several proposed technical modifications in LSG. They can influence complication rates or weight loss like the length of antrum resection, the size of Fouchet tube, or the reinforcement of staple line [1-4]. Besides that other concepts regarding reduction of size or number of trocars have also been applied. LSG has been

To compare postoperative outcomes of minimally invasive gastrectomy (MIG) to open gastrectomy (OG) for cancer during the introduction of MIG in the Netherlands. Between 2011 and 2015, the use of MIG increased from 4% to 53% in the Netherlands. This population-based cohort study included all patients with curable gastric adenocarcinoma that underwent gastrectomy between 2011 and 2015, registered in the Dutch Upper GI Cancer Audit. Patients with missing preoperative data, and patients in whom no lymphadenectomy or reconstruction was performed were excluded. Propensity score matching was applied to create comparable groups between patients receiving MIG or OG, using year of surgery and other potential confounders. Morbidity, mortality, and hospital stay were evaluated. Of the 1697 eligible patients, 813 were discarded after propensity score matching; 442 and 442 patients who underwent MIG and OG, respectively, remained. Conversions occurred in 10% of the patients during MIG. Although the overall postoperative morbidity (37% vs 40%, P = 0.489) and mortality rates (6% vs 4%, P = 0.214) were comparable between the 2 groups, patients who underwent MIG experienced less wound complications (2% vs 5%, P = 0.006). Anastomotic leakage occurred in 8% of the patients after MIG, and in 7% after OG (P = 0.525). The median hospital stay declined over the years for both procedures (11 to 8 days, P < 0.001). Overall, hospital stay was shorter after MIG compared with OG (8 vs 10 days, P < 0.001). MIG was safely introduced in the Netherlands, with overall morbidity and mortality comparable with OG, less wound complications and shorter hospitalization.

Robotic surgery was developed in response to the limitations and drawbacks of laparoscopic surgery. Since 1997 when the first robotic procedure was performed various papers pointed the advantages of robotic-assisted laparoscopic surgery, this technique is now a reality and it will probably become the surgery of the future. The aim of this paper is to present our preliminary experience with the three-arms "da Vinci S surgical system", to assess the feasibility of this technique in various abdominal and thoracic procedures and to point out the advantages of the robotic approach for each type of procedure. Between 18 January 2008 and 18 January 2009 153 patients (66 men and 87 women; mean age 48,02 years, range 6 to 84 years) underwent robotic-assisted surgical procedures in our institution; we performed 129 abdominal and 24 thoracic procedures, as follows: one cholecystectomy, 14 myotomies with Dor fundoplication, one gastroenteroanastomosis for unresectable antral gastric cancer, one transthoracic esophagectomy, 14 gastrectomies, one polypectomy through gastrotomy, 22 splenectomies,7 partial spleen resections, 22 thymectomy, 6 Nissen fundoplications, one Toupet fundoplication, one choledocho-duodeno-anastomosis, one drainage for pancreatic abscess, one distal pancreatectomy, one hepatic cyst fenestration, 7 hepatic resections, 29 colonic and rectal resections, 5 adrenalectomies, 12 total radical hysterectomies and pelvic lymphadenectomy, 3 hysterectomies with bilateral adnexectomy for uterine fibroma, one unilateral adnexectomy, and 2 cases of cervico-mediastinal goitre resection. 147 procedures were robotics completed , whereas 6 procedures were converted to open surgery due to the extent of the lesion. Average operating room time was 171 minutes (range 60 to 600 minutes, Median length of stay was 8,6 days (range 2 to 48 days). One system malfunctions was registered. Post-operatory complications occurred in 14 cases. There were no deaths. Our preliminary experience

In this study, we aimed to evaluate the rarely reported long-term nutritional results of patients with gastric cancer after curative gastrectomy. We retrospectively reviewed the prospectively collected medical records of 658 patients who underwent radical gastrectomy with curative intent for gastric cancer from January 2008 to December 2009 and had no recurrences. All patients were followed for 5 years. Nutritional statuses were assessed using measurements of body weight, serum hemoglobin, total lymphocyte count (TLC), protein, albumin, cholesterol, and nutritional risk index (NRI). Patients who underwent total gastrectomy had lower body weights, hemoglobin, protein, albumin, and cholesterol levels. TLC and NRI valued after the first postoperative year (P<0.05), and lower hemoglobin and NRI valued during the fifth postoperative year than patients who underwent distal gastrectomy (P<0.05). Patients who received adjuvant chemotherapy after gastrectomy had lower hemoglobin, protein, albumin, and cholesterol levels. TLC and NRI valued during the first postoperative year, than those who underwent gastrectomy only (P<0.05). Regarding post-distal gastrectomy reconstruction, those who underwent Roux-en-Y had lower cholesterol levels than did those who underwent Billroth-I and Billroth-II reconstruction at the first and fifth years after gastrectomy, respectively (P<0.05). Patients undergoing total or distal gastrectomy with Roux-en-Y anastomosis or adjuvant chemotherapy after surgery should be monitored carefully for malnutrition during the first postoperative year, and patients undergoing total gastrectomy should be monitored for malnutrition and anemia for 5 years.

Laparoscopic sleeve gastrectomy (LSG) is gaining acceptance as a stand-alone bariatric procedure with proven efficacy on weight loss and obesity-related comorbidities. A specific and potentially severe complication of LSG is the staple line leak (SLL). Our aim was to report the SLL rate and its management in a prospective cohort of 378 LSGs. A total of 378 patients underwent LSG from July 2005 to July 2011. The gastric transection was performed by an initial 60 mm firing of 4.5 mm staples at the antrum and successive 60 mm firings of 3.5 mm staples at the gastric body and fundus toward the left diaphragmatic crus. A 36 Fr bougie was used to calibrate the gastric tube. The staple line was systematically reinforced with a partial-thickness running suture. The overall complications and SLL rate were 20/378 (5.29%) and 9/378 (2.38%), respectively. SLLs were managed by laparoscopic (n=2) or open (n=1) exploration, drainage and endoscopic self-expandable covered stent, computed tomography-guided percutaneous drainage (n=2), or a self-expandable covered stent alone (n=4). Medical support including total parenteral nutrition and adapted antibiotics was started in all patients. The combined treatment modalities were successful in all cases. SLL was the most common complication of LSG accounting for half of the overall complications. Percutaneous drainage and self-covered stents combined with antibiotics and parenteral nutrition are effective for SLL and should be proposed as first-line treatment in stable patients.

Post-gastrectomy anastomosis site obstruction is a relatively rare complication after a subtotal gastrectomy. We present a case of a 75-year-old man who underwent a truncal vagotomy, omental patch, gastrojejunostomy, and Braun anastomosis for duodenal ulcer perforation and a gastric outlet obstruction. Following the 10(th) postoperative day, the patient complained of abdominal discomfort and vomiting. We diagnosed post-gastrectomy anastomosis site obstruction by an upper gastrointestinal series and an upper endoscopic examination. We inserted a self-expandable metallic stent (SEMS) at the anastomosis site. The stent was fully expanded after deployment. On the day following the stent insertion, the patient began to eat, and his abdominal discomfort was resolved. This paper describes the successful management of post-gastrectomy anastomosis site obstruction with temporary placement of a SEMS.

Peritoneal dialysis (PD) is a commonly accepted method of treating end-stage renal disease (ESRD). Various laparoscopic techniques for the placement of PD catheter have been described. In this study, we developed a novel modified laparoscopic technique for PD catheter placement and evaluated the early results. A straight Tenckhoff PD catheter was placed employing the modified technique in 39 consecutive patients with ESRD from May 2013 to April 2016. The technique is laparoscopically guided intra-abdominal fixation of the PD catheter tip at one point by using suture passer hernia forceps. Individual information including sex, age, primary disease etiology, complications, surgical duration, morbidity, mortality and catheter survival was collected and analyzed. The modified laparoscopic procedure was effectively performed in all patients with a mean operative time of 45 ± 7 min. No conversions from laparoscopy to open surgery of catheter placement occurred. There was one case showing early pericatheter leakage. There were no serious complications, such as bleeding, abdominal wall hernias, distal catheter cuff extrusion and infections of the exit site or tunnel during surgery or the postoperative duration. No mortality was observed in this group of patients. The 6-month follow-up study showed 100% catheter-related complication-free survival. Our modified laparoscopic intra-abdominal fixation technique using suture passer hernia forceps is a simple and safe method for PD catheter placement and is effective in minimizing the risk of catheter migration.

Surgeons constantly struggle with the formation of condensation on the lens of a laparoscope, which prolongs procedures and reduces visibility of the abdominal cavity. The goal of this project was to build a device that would direct a flow of carbon dioxide (CO2) into an open chamber surrounding the lens of a laparoscope, acting to keep moisture away from the lens and eliminate condensation. The device isolates the lens of the laparoscope from the humid environment of the intraperitoneal cavity by creating a microenvironment of dry CO2. This was accomplished by building a communicating sleeve that created an open chamber around the distal 2 to 3 cm of the scope. Into this cavity, dry cool CO2 was pumped in from an insufflator so that the path of the gas would surround the lens of the scope and escape through a single outlet location through which the scope views the intraperitoneal cavity. This chamber is proposed to isolate the lens with a high percentage of dry CO2 and low humidity. The device was tested in 7 different adverse conditions that were meant to challenge the ability of the device to maintain the viewing field with no perceptible obstruction. In all of the conditions tested, 25 trials total, the device successfully prevented and/or eliminated laparoscopic lens fogging. The device designed for this project points to the potential of a simple and effective mechanical method for eliminating laparoscopic lens fogging.

Laparoscopic resection for transverse colon cancer remains controversial. The aim of this study is to investigate the short- and long-term outcomes of laparoscopic surgery for transverse colon cancer. A total of 278 patients with transverse colon cancer from a single institution were included. All patients underwent curative surgery, 156 patients underwent laparoscopic resection (LR), and 122 patients underwent open resection (OR). The short- and long-term results were compared between two groups. Baseline demographic and clinical characteristics were comparable between two groups. Conversions were required in eight (5.1 %) patients. LR group was associated with significantly longer median operating time (180 vs. 140 min; P < 0.001). Median estimated blood loss was significantly less in LR group (90 vs. 100 ml; P = 0.001). Time to first flatus and oral intake was significantly earlier in LR group. Perioperative mortality and morbidity rate were not significantly different between two groups. Tumor size, number of lymph nodes harvested, length of proximal, and distal resection margin were comparable between two groups. Postoperative hospital stay was significantly shorter in LR group (9 vs. 10d; P < 0.001). Five-year disease-free survival and overall survival rate were similar between two groups. Laparoscopic resection for transverse colon cancer is associated with better short-term outcomes and equivalent long-term oncologic outcomes.

The performance of most bariatric procedures within an Enhanced Recovery After Surgery (ERAS) programs has resulted in considerable advantages, including a reduction in the length of hospital stay to 2 to 3 days. However, some postoperative complications can appear after the patient has been discharged. The aim of this study was to investigate the efficacy of various acute-phase parameters determined 24 and 48 hours after laparoscopic sleeve gastrectomy (LSG) as bariatric procedure, for predicting septic complications, such a surgical site infection (SSI), in the postoperative course. A prospective study of 115 morbidly obese patients who underwent LSG within an ERAS program between 2012 and 2015 was conducted. Blood analysis was performed 24 and 48 hours after surgery. Acute-phase parameters (C-reactive protein [CRP], procalcitonin, and fibrinogen) and WBC count were investigated. Septic complications were observed in 13 patients (11.3%). Using receiver operating characteristic analysis at 24 hours postoperatively, a cutoff level of CRP at 70 mg/L achieved 85% sensitivity and 90% specificity for predicting SSI, and a cutoff level of procalcitonin at 0.2 ng/mL achieved 70% sensitivity and 90% specificity. At 48 hours postoperatively, a cutoff level of CRP at 150 mg/L and procalcitonin at 0.95 ng/mL achieved 100% sensitivity and 100% specificity for predicting SSI. The use of CRP and procalcitonin in the first day and especially in the second day postoperative can predict septic complications after LSG. This is most useful for patients within an ERAS program who will be discharged early. Copyright © 2016 American College of Surgeons. Published by Elsevier Inc. All rights reserved.

This study investigated long-term trends in hematological and nutritional parameters after gastrectomy for gastric cancer and evaluated the influence of the reconstruction type on these trends. The medical records of 558 patients who underwent curative gastrectomy with standard lymph node dissection for stage I gastric cancer between January 2006 and December 2013 were reviewed. The hematological and nutritional parameters evaluated included hemoglobin, ferritin, vitamin B 12 , total protein, albumin, total cholesterol, triglyceride, and calcium. The patients were followed up for 6 months postoperatively and then annually until death, cancer recurrence, or follow-up loss. In the long term, ferritin and triglyceride gradually decreased after gastrectomy, while the other parameters decreased slightly or were stable. In the comparisons according to reconstruction type, the Roux-en-Y group had the lowest levels of hemoglobin, ferritin, vitamin B12, total protein, albumin, and total cholesterol beginning 6 months postoperatively compared with the Billroth I and II groups. However, only ferritin and vitamin B 12 had significant differences in the 5-year cumulative incidences of deficiency/reduction according to the reconstruction type, whereas albumin, triglyceride, total cholesterol, and calcium did not. Although malabsorption and malnutrition are common in patients after a gastrectomy, most nutritional parameters were stable or decreased slightly in the long-term and were not markedly influenced by the reconstruction type or extent of gastrectomy. Therefore, for more accurate nutritional assessment after gastrectomy, multidirectional monitoring should be considered rather than simply measuring biochemical parameters.

Omentin is a novel adipokine with insulin-sensitizing effects expressed predominantly in visceral fat. We investigated serum omentin levels and its mRNA expression in subcutaneous adipose tissue (SCAT) of 11 women with type 2 diabetes mellitus (T2DM), 37 obese non-diabetic women (OB) and 26 healthy lean women (C) before and after various weight loss interventions: 2-week very-low-calorie diet (VLCD), 3-month regular exercise and laparoscopic sleeve gastrectomy (LSG). At baseline, both T2DM and OB groups had decreased serum omentin concentrations compared with C group while omentin mRNA expression in SCAT did not significantly differ among the groups. Neither VLCD nor exercise significantly affected serum omentin concentrations and its mRNA expression in SCAT of OB or T2DM group. LSG significantly increased serum omentin levels in OB group. In contrast, omentin mRNA expression in SCAT was significantly reduced after LSG. Baseline fasting serum omentin levels in a combined group of the studied subjects (C, OB, T2DM) negatively correlated with BMI, CRP, insulin, LDL-cholesterol, triglycerides and leptin and were positively related to HDL-cholesterol. Reduced circulating omentin levels could play a role in the etiopathogenesis of obesity and T2DM. The increase in circulating omentin levels and the decrease in omentin mRNA expression in SCAT of obese women after LSG might contribute to surgery-induced metabolic improvements and sustained reduction of body weight.

Abstract Enhanced recovery after surgery (ERAS) is increasingly used in several abdominal surgeries to accelerate postoperative recovery and reduce the length of stay. The aim of this study was to investigate the pattern of functional recovery after gastrectomy in patients undergoing ERAS and to analyze factors that affect postoperative recovery. In all, 168 gastric cancer patients enrolled in a clinical trial evaluating ERAS compliance after gastrectomy were prospectively assessed with respect to postoperative functional recovery using discharge criteria, evaluating 4 major functional outcomes: adequate pain control, ability to mobilize and self-care, tolerance of oral intake, and no abnormal physical findings or laboratory test. The mean completion time of overall discharge criteria was 5.1 ± 3.2 days. The mean completion time for each dimension were 4.4 ± 0.9 days for adequate pain control, 4.1 ± 0.8 days for ability to mobilize and self-care, 4.3 ± 1.1 days for no abnormal physical signs or laboratory test, and 4.6 ± 1.2 days for tolerance of oral intake. The mean length of stay was 7.2 ± 3.2 days, and readmission rate was 2.4% (n = 4). There was 9.5% (n = 16) of morbidity and no hospital mortality. Female sex (P < 0.001) and age (≥65 years; P = 0.049) were significantly associated with a slower recovery in tolerance of oral intake, and total gastrectomy was significantly associated with delayed completion of adequate pain control (P = 0.003). Functional recovery after gastrectomy can be achieved after about 5 days in patients undergoing ERAS. Female sex, old age, and total gastrectomy are factors that delay normal functional recovery after gastrectomy. PMID:27057836

To study and assess clinical outcomes of various modes of treatment for perforated giant gastric ulcer in an emergency setting. From May 2010 to February 2013, 20 cases of perforated giant gastric ulcer (> 2 cm) were operated on in an emergency setting. All the patients presented with features of peritonitis and were resuscitated aggressively before taking for surgery. In the first 4 cases, primary closure was done after taking a biopsy and among these, the 3(rd) case also underwent partial distal gastrectomy and gastrojejunostomy and the 4(th) case underwent a radical subtotal gastrectomy with D2 lymphadenectomy and gastrojejunostomy for malignancy. All the remaining 16 cases underwent partial distal gastrectomy and gastrojejunostomy. Among the first 4 cases, 2 had an uneventful recovery and were discharged on the 6(th) postoperative day. The 3(rd) and 4(th) patients developed gastric fistula, leading to prolonged hospitalization. For the 3(rd) patient, conservative management was tried for 1 wk, followed by partial distal gastrectomy and gastrojejunostomy, and he was discharged on the 20(th) day after admission, while the 4(th) patient underwent a radical subtotal gastrectomy with D2 lymphadenectomy and gastrojejunostomy. Postoperatively, he developed adult respiratory distress syndrome, multiorgan dysfunction syndrome and expired on the 3(rd) postoperative day of the second surgery. All the remaining 16 patients underwent partial distal gastrectomy and gastrojejunostomy and recovered well. Among these, 4 of them were malignant and the remaining were benign ulcers. All had an uneventful recovery. The percentage of malignancy in our series was 30% (6 out of 20 cases). In our study, 86% had an uneventful recovery, complications were seen in about 10%, and mortality was about 5%. In giant gastric ulcer, the chances of malignancy and leak after primary closure are high. So, we feel that partial distal gastrectomy and gastrojejunostomy is better.

Laparoscopic sleeve gastrectomy (LSG) has proven to be successful in weight reduction but with potential loss of bone mass. Previous studies indicated that bone morphogenetic protein 4 (BMP4) plays an important role in both bone formation and glucose-lipid metabolism. This study aimed to investigate the changes in bone mineral density (BMD), bone metabolic parameters, and serum BMP4 levels in obese Chinese subjects after LSG. Seventy-one obese patients (34 males, age 31.70 ± 9.61 years and 37 females, age 32.80 ± 11.45 years) were enrolled. BMD (at the right hip, femoral neck, and lumbar spine 1-4 (L1-L4)) was measured by dual-energy X-ray absorptiometry, bone metabolic markers, and routine anthropometric/laboratory biochemical parameters at baseline, 3, 6, and 12 months after LSG (abbreviated as 3, 6, and 12 M post-LSG, respectively) were recorded. Serum BMP4 levels were measured by enzyme-linked immunosorbent assay. LSG led to dramatic weight loss with improved glucose-lipid metabolism in all patients. In females, BMD was significantly decreased at the right hip at all time points studied and at the femoral neck at 6 and 12 M post-LSG (P < 0.05 or P < 0.01). In males, BMD was not significantly changed (all P > 0.05). Intriguingly, serum BMP4 levels were reduced slightly at 3 M post-LSG (P = 0.463) and were significantly at 6 M post-LSG (from 75.51 ± 16.54 to 65.40 ± 10.51 pg/mL, P = 0.048) in females, but unchanged in males (all P > 0.05). Vitamin D and 25-hydroxy vitamin D were increased in males at 12 M post-LSG (all P < 0.05). Osteocalcin was increased in males at all time points studied and in females at 3 and 6 M post-LSG (all P < 0.05). Type I collagen was increased in males at 3 and 6 M post-LSG and in females at all the time points studied (all P < 0.05). The effect of LSG on BMD differs between genders, decreasing significantly in females while remaining unchanged in males. Moreover

Bochdalek hernia (BH) is generally congenital, presenting with respiratory distress. However, this pathology is rarely detected in adults. Some adult cases of BH present with symptoms attributed to the hernia, but incidental detection of BH is increasing among asymptomatic adults due to advances in imaging modalities. This report presents the management of incidental BH patients detected in the preoperative period of gastric cancer. An asymptomatic 76-year-old woman was diagnosed with advanced gastric cancer during follow-up after radiotherapy for uterine cervical cancer. Computed tomography (CT) was performed to exclude metastatic gastric cancer, incidentally detecting right-sided BH. We planned distal gastrectomy with lymph node dissection for gastric cancer and simultaneous repair of BH using a laparoscopic approach. We performed laparoscopic gastrectomy for gastric cancer and investigated the right-sided BH to assess whether repair during surgery was warranted. Herniation of the liver into the right hemithorax was observed, but was followed-up without surgical repair because the right hepatic lobe was adherent to the remnant right anterior hemidiaphragm and covered the huge defect in the right hemidiaphragm. No intra- or postoperative pneumothorax was observed during pneumoperitoneum. Regardless of symptoms, repair of adult BH is generally recommended to prevent visceral incarceration. However, BH in asymptomatic adults appears to be more common than previously reported in the literature. Surgeons need to consider the management of incidental BH encountered during thoracic or abdominal surgery.

Background Post-operative loss-of-control (LOC) eating is related to poorer weight loss outcomes following bariatric surgery, but little is known about LOC eating following sleeve gastrectomy surgery. Objectives To examine LOC eating severity and weight loss following sleeve gastrectomy. Setting University School of Medicine, U.S. Methods Participants were 71 individuals (84.5% female; n=60) who underwent sleeve gastrectomy surgery within the previous 4–9 months and reported LOC eating at least once weekly during the previous 28 days. LOC eating was assessed using the Eating Disorder Examination (EDE) Bariatric Surgery Version. Current mean age and body mass index were 47.3 (SD=10.1) years and 37.9 (SD=8.2) kg/m2. Two groups, bariatric binge-eating disorder (Bar-BED) and loss-of-control eating only (LOC-Only) were created based on modified binge-eating disorder (BED) criteria, which excluded the “unusually large quantity of food” criterion due to limited gastric capacity post-surgery. Bar-BED criteria mirrored BED criteria and consisted of the following: at least 12 LOC eating episodes over the prior three months (once weekly), 3 of 5 associated symptoms, marked distress over LOC eating, and lack of regular compensatory behaviors. Results Based on these revised criteria, 49.3% (n=35) were classified as the Bar-BED group and 50.7% (n=36) as the LOC-Only group. Compared to the LOC-Only group, the Bar-BED group had significantly greater EDE global and subscale scores and lower percent weight loss by six months post-surgery. Conclusions Findings suggest LOC eating that parallels BED post-surgery is associated with poorer outcomes following sleeve gastrectomy including poorer weight loss and greater severity of eating-disorder psychopathology.

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

Sleeve gastrectomy (SG) is currently the most common bariatric procedure in France. It achieves both adequate excess weight loss and significant reduction of comorbidities. However, leak is still the most common complication after SG. Nevertheless, its risk of occurrence is <3% in specialized centers. Its management is difficult, long, and challenging. Although the procedure is commonly endoscopic and nonoperative, the management of post-SG fistulas could sometimes be surgical, including peritoneal lavage, abscess drainage, disrupted staple line suturing, resleeve, gastric bypass, or total gastrectomy. Roux-en-Y fistulojejunostomy (RYFJ) has been described as a salvage option. In this study, we report the early results of RYFJ for post-SG fistula, emphasizing indications, operative technique, and short-term outcome. Between January 2007 and December 2012, we treated 62 patients with post-SG fistula. Before surgery, intra-abdominal or thoracic abscesses or collections were either excluded or treated by computed tomographic scan-guided drainage or even surgery. Endoscopic stenting was then attempted. After optimization of the nutritional status in case of failure of endoscopic measures, some of the patients underwent RYFJ. Between January 2007 and December 2012, a total of 21 patients (16 women and 5 men) had RYFJ for post-SG fistula. Mean age was 47 years (range, 22-59 years). Procedures were performed laparoscopically in all but 3 cases. The rate of secondary conversion to laparotomy was 11.1%. The was no mortality. The postoperative morbidity rate was less than 5%. The rate of fistula control was eventually 100%. RYFJ is a safe and feasible salvage procedure for the treatment of patients with post-SG fistula. Longer outcome analysis is, however, needed especially regarding the physiological and metabolic behavior of the procedure.

Function-preserving surgery for gastric cancer: current status and future perspectives

The number of early gastric cancer (EGC) cases has been increasing because of improved diagnostic procedures including endoscopy and screening systems. Therefore, function-preserving gastrectomy (FPG) for EGC with the expectation of better quality of life (QOL) after surgery may be increasingly utilized, due to its association with low rate of lymph node metastasis and excellent survival and the possibility of employing less invasive procedures such as laparoscopic gastrectomy in combination. Pylorus-preserving gastrectomy (PPG) with curative intent lymph node dissection is a representative FPG that has been used in EGC, and its superiorities, indications, limitations, and survival benefits have already been reported in several retrospective studies. Laparoscopic proximal gastrectomy (LAPG) has also been employed in EGC of the upper third of the stomach; however, LAPG was found to be associated with major issues in achieving a balance between swallowing and reflux prevention. In patients with EGC in the upper third of the stomach, laparoscopy-assisted subtotal gastrectomy with a preserved, albeit very small, stomach may provide a better QOL and fewer postoperative complications. FPG is recommended as a surgical treatment for EGC if the indication is accurately diagnosed and strictly confirmed; however, these techniques in laparoscopic surgery present technical difficulties to surgeons without a certain degree of skills. Although many retrospective studies revealed the functional benefits or oncological safety with FPG, further prospective studies using large case series are necessary to reveal the value of FPG compared with the conventional procedures.

Although proximal gastrectomy has become a procedure of choice for patients' early cancer in the upper third of stomach, no clinical guide for optimal gastric resection in order to avoid postoperative jejunal ulcer is available. The aim of this study was to investigate whether determining the distribution of parietal and chief cells of the stomach using Congo red test is clinically relevant. The F-line was defined as a boundary line between fundic and intermediate area of the stomach according to the pathological findings in 29 patients who underwent total gastrectomy for early gastric cancer, whereas the f-line was regarded as a boundary line between intermediate and pyloric area. In the additional 6 patients undergoing vagus-preserving proximal gastrectomy with jejunal pouch interposition, endoscopic Congo red test was preoperatively performed to determine the F-f-line. The distances from the pyloric ring to f-line on the lesser and greater curvatures were variable. Long-term outcomes of proximal gastrectomy guided by preoperative endoscopic Congo red test were favorable. It is suggested that preoperative endoscopic Congo red test is useful to determine the appropriate cutting line in order to avoid postoperative jejunal ulcer after proximal gastrectomy.

Presently, there is no scientific evidence supporting a definite role for follow-up after gastrectomy for cancer, and clinical practices are quite different around the globe. The aim of this consensus conference was to present an ideal prototype of follow-up after gastrectomy for cancer, based on shared experiences and taking into account the need to rationalize the diagnostic course without losing the possibility of detecting local recurrence at a potentially curable stage. On June 19-22, 2013 in Verona (Italy), during the 10th International Gastric Cancer Congress (IGCC) of the International Gastric Cancer Association, a consensus meeting was held, concluding a 6-month, Web-based, consensus conference entitled "Rationale of oncological follow-up after gastrectomy for cancer." Forty-eight experts, with a geographical distribution reflecting different health cultures worldwide, participated in the consensus conference, and 39 attended the consensus meeting. Six statements were finally approved, displayed in a plenary session and signed by the vast majority of the 10th IGCC participants. These statements are attached as an annex to the Charter Scaligero on Gastric Cancer. After gastrectomy for cancer, oncological follow-up should be offered to patients; it should be tailored to the stage of the disease, mainly based on cross-sectional imaging, and should be discontinued after 5 years.

A 76-year-old man was admitted to our hospital for treatment of gastric tube cancer(cT2N0M0, cStage II A)detected by a screening upper gastrointestinal endoscopy. Seven years previously, he had undergone subtotal esophagectomy for esophageal cancer with gastric pull-up via the retrosternal route. At that time, he experienced cardiopulmonary arrest due to ventric- ular tachycardia. He was in a state of poor nutrition(BMI 15 kg/m2). Therefore, reducing operative stress as much as possible, minimizing complications after surgery, and aiming for a satisfactory postoperative course are all important goals. Based on his past history, we performed distal gastrectomy(resection of the distal part of the gastric tube)without excision of the right gastroepiploic artery. The postoperative course was uneventful. He was discharged 40 days after surgery. By considering the risks of surgery due to cardiac dysfunction and malnutrition, we were able to provide effective and safe therapy for the patient.

Laparoscopy-assisted distal gastrectomy (LADG) is widely used for gastric cancer (GC) patients nowadays. This study aimed to investigate the time trend of outcomes so as to describe the learning curve for GC patients with LADG at a single medical institution in western China over a 6-year period.A total of 246 consecutive GC patients with LADG were divided into 5 groups (group A: 46 patients from 2006 to 2007; group B: 47 patients in 2008; group C: 49 patients in 2009; group D: 73 patients in 2010; and group E: 31 patients in 2011). All surgeries were conducted by the same surgeon. Comparative analyses were successively performed by Mann-Whitney U test or Student t test among the 5 different groups for the clinical data, including clinicopathologic characteristics, surgical parameters, postoperative course, and survival outcomes, through which the learning curve was described.There were no differences in the baseline information among the 5 groups (P > 0.05), and the proportion of advanced GC patients with LADG slightly increased from 58.7% to 77.4% during the 6 years. Besides, the proportion of D2/D2+ lymphadenectomy and the number of retrieved lymph nodes gradually grew from 60.9% to 80.6% and from 20.0 to 28.8, respectively. In addition, the operation time decreased from 299.2 to 267.8 minutes, while the estimated blood loss dropped from 175.2 to 146.8 mL. Furthermore, some surgical parameters (surgical duration and blood loss) and postoperative course (such as postoperative complications, the time to ambulation, to first flatus, and to first liquid intake as well as the length of hospital stay) were all observed to be significantly different between group A and other groups (P < 0.05), illustrating a similar downward trend and remaining stable to form a plateau after 46 cases in group A. However, no difference on overall survival was found among these 5 groups, and multivariate analysis indicated that factors, such as age, tumor differentiation, tumor

AIM: To study the risk factors for morbidity and mortality following total gastrectomy. METHODS: We retrospectively reviewed the records of 125 consecutive patients who underwent total gastrectomy for gastric cancer at the Second Affiliated Hospital of Zhejiang University School of Medicine between January 2003 and March 2008. RESULTS: The overall morbidity rate was 20.8% (27 patients) and the mortality rate was 3.2% (4 patients). Morbidity rates were higher in patients aged over 60 [odds ratio (OR) 4.23 (95% confidence interval (CI) 1.09 to 12.05)], with preoperative comorbidity [with vs without, OR 1.25 (95% CI 1.13 to 8.12)], when the combined resection was performed [combined resection vs total gastrectomy only, OR 2.67 (95% CI 1.58 to 5.06)]. CONCLUSION: Age, preoperative comorbidity and combined resection were independently associated with the rate of morbidity after total gastrectomy for gastric cancer. PMID:19030212

Although conventional laparoscopic and hand-assisted laparoscopic surgery for colorectal cancer is widely used today, there remain many technical challenges especially for right colon cancer in obese patients. Herein, we develop a novel hand-assisted laparoscopic surgery (HALS) with complete mesocolic excision (CME), D3 lymphadenectomy, and a total "no-touch" isolation technique (HALS-CME) in right hemicolectomy to overcome these issues. According to previous clinic practice, this novel procedure is not only feasible and safe but has several technical merits. However, the feasibility, short-term minimally invasive virtues, long-term oncological superiority, and potential total "no-touch" isolation technique benefits of HALS-CME should be confirmed by a prospective randomized controlled trial. This is a single-center, open-label, noninferiority, randomized controlled trial. Eligible participants will be randomly assigned to the HALS-CME group or to the laparoscopic surgery with CME, D3 lymphadenectomy, and total "no-touch" isolation technique (LAP-CME) group, or to conventional laparoscopic surgery with CME and D3 lymphadenectomy (cLAP) group at a 1:1:1 ratio using a centralized randomization list. Primary endpoints include safety, efficacy, and being oncologically clear, and 3-year disease-free, progression-free, and overall survival. Second endpoints include operative outcomes (operation time, blood loss, and incision length), pathologic evaluation (grading the plane of surgery, length of proximal and distal resection margins, distance between the tumor and the central arterial high tie, distance between the nearest bowel wall and the same high tie, area of mesentery resected, width of the chain of lymph-adipose tissue, length of the central lymph-adipose chain, number of harvested lymph nodes), and postoperative outcomes (pain intensity, postoperative inflammatory and immune responses, postoperative recovery). This trial will provide valuable clinical evidence

Approximately 20% of patients develop some complications after gastrectomy. These complications should be treated appropriately to achieve a positive outcome. The records of 6 patients with postoperative intra-abdominal abscesses treated with interventional radiology (IVR) were analyzed. The cause of abscess was anastomotic leakage in 4 patients and contaminated surgery after gastric perforation in 2 patients. Intra-abdominal abscesses were detected on postoperative day 12 (median), and an IVR-guided drainage tube was inserted with a median interval of 1 day. The drainage tube was kept in place for 26 days (median), and patients were discharged 6.5 days (median) after drainage tube removal. No patients were converted to open surgery. Early IVR-guided drainage was essential and effective for intra-abdominal abscess treatment after gastrectomy.

Delta-shaped anastomosis is usually applied for an intracorporeal gastrogastrostomy in totally laparoscopic pylorus-preserving gastrectomy (TLPPG). However, the remnant stomach is slightly twisted around the anastomosis because it connects in side-to-side fashion. To realize an intracorporeal end-to-end gastrogastrostomy using an endoscopic linear stapler, we invented a novel method including a unique anastomotic technique. In this new approach, we first made small gastrotomies at the greater and lesser curvatures of the transected antrum and then pierced it using an endoscopic linear stapler. After the pierced antrum and the proximal remnant stomach were mechanically connected, the gastrotomies and stapling lines were transected using an endoscopic linear stapler, creating an intracorporeal end-to-end gastrogastrostomy. We have named this technique the "piercing method" because piercing the stomach is essential to its implementation. Between October 2015 and June 2017, 26 patients who had clinically early gastric cancer at the middle third of the stomach without clinical evidence of lymph node metastasis underwent TLPPG involving the novel method. The 26 patients successfully underwent an intracorporeal mechanical end-to-end gastrogastrostomy by the piercing method. The median operation time of the 26 patients was 272 min (range 209-357 min). With the exception of one gastric stasis, no problems associated with the piercing method were encountered during and after surgery. The piercing method can safely create an intracorporeal mechanical end-to-end gastrogastrostomy in TLPPG. Piercing the stomach using an endoscopic linear stapler is a new technique for gastrointestinal anastomosis. This method should be considered if the surgical aim is creation of an intracorporeal end-to-end gastrogastrostomy in TLPPG.

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

Minimally invasive techniques for gastric cancer surgery have recently been introduced in the Netherlands, based on a proctoring program. The aim of this population-based cohort study was to evaluate the short-term oncological outcomes of minimally invasive gastrectomy (MIG) during its introduction in the Netherlands. The Netherlands Cancer Registry identified all patients with gastric adenocarcinoma who underwent gastrectomy with curative intent between 2010 and 2014. Multivariable analysis was performed to compare MIG and open gastrectomy (OG) on lymph node yield (≥15), R0 resection rate, and 1-year overall survival. The pooled learning curve per center of MIG was evaluated by groups of five subsequent procedures. Between 2010 and 2014, a total of 277 (14%) patients underwent MIG and 1633 (86%) patients underwent OG. During this period, the use of MIG and neoadjuvant chemotherapy increased from 4% to 39% (p < 0.001) and from 47% to 62% (p < 0.001), respectively. The median lymph node yield increased from 12 to 20 (p < 0.001), and the R0 resection rate remained stable, from 86% to 91% (p = 0.080). MIG and OG had a comparable lymph node yield (OR, 1.01; 95% CI, 0.75-1.36), R0 resection rate (OR, 0.86; 95% CI, 0.54-1.37), and 1-year overall survival (HR, 0.99; 95% CI, 0.75-1.32). A pooled learning curve of ten procedures was demonstrated for MIG, after which the conversion rate (13%-2%; p = 0.001) and lymph node yield were at a desired level (18-21; p = 0.045). With a proctoring program, the introduction of minimally invasive gastrectomy in Western countries is feasible and can be performed safely.

Are there risk factors that increase the rate of staple line leakage in patients undergoing primary sleeve gastrectomy for morbid obesity?

Laparoscopic sleeve gastrectomy (LSG) is currently being performed with increasing frequency worldwide. It offers an excellent weight loss and resolution of comorbidities in the short term with a very low incidence of complications. However, the ever present risk of a staple line leak is still a major concern. Since 2005, data from obese patients that undergo bariatric procedures in Germany are prospectively registered in an online database and analyzed at the Institute of Quality Assurance in Surgical Medicine. For the current analysis, all patients that had undergone primary sleeve gastrectomy for morbid obesity within a 7-year period were considered. Using the GBSR, data from 5.400 LSGs were considered for analysis. Staple line leak rate decreased during the study period from 6.5 to 1.4 %. Male gender, higher BMI, concomitant sleep apnea, conversion to laparotomy, longer operation time, use of both buttresses and oversewing, and the occurrence of intraoperative complications were associated with a significantly higher leakage rate. On multivariate analysis, operation time and year of procedure only had a significant impact on staple line leak rate. The results of the current study demonstrated that there are factors that increase the risk of a leakage which would enable surgeons to define risk groups, to more carefully select patients, and to offer a closer follow-up during the postoperative course with early recognition and adequate treatment. All future efforts should be focused on a further reduction of serious complications to make the LSG a widely accepted and safer procedure.

We previously reported the use of an inverted T-shaped method to obtain a suitable view for hand sewing to close the common entry hole when the linear stapler was fired for esophagojejunostomy after laparoscopic total gastrectomy (LTG). This conventional method involved insertion of the fixed cartridge fork to the Roux limb and the fine movable anvil fork to the esophagus to avoid perforation of the jejunum. However, insertion of the movable anvil fork to the esophagus during this procedure often requires us to strongly push down the main body of the stapler with the fixed cartridge fork to bring the direction of the anvil fork in line with the direction of the long axis of the esophagus while controlling the opening of the movable anvil fork. We therefore modified this complicated inverted T-shaped method using a linear stapler with a movable cartridge fork. This modified method involved insertion of the movable cartridge fork into the Roux limb followed by natural, easy insertion of the fixed anvil fork into the esophagus without controlling the opening of the movable cartridge fork. We performed LTG in a total of 155 consecutive patients with gastric cancer from November 2007 to December 2015 in Kyushu University Hospital. After LTG, we performed the conventional inverted T-shaped method using a linear stapler with a fixed cartridge fork in 61 patients from November 2007 to July 2011 (fixed cartridge group). From August 2011, we used a linear stapler with a movable cartridge fork and performed the modified inverted T-shaped method in 94 patients (movable cartridge group).

Endoscopic stenting is a relatively new technique for the treatment of post sleeve gastrectomy complications. Partially covered stents are used in this method to minimise the risk of migration but they are associated with difficulties with removal. Patients requiring emergency stenting following sleeve gastrectomy underwent insertion of a partially covered metallic stent. One month later, if the stent was not easily removable, a fully covered overlapping stent was inserted and the patient was readmitted 2 weeks later for removal of both stents. Four patients required stenting following sleeve gastrectomy leaks, and one patient required stenting for a stricture. In these cases, a 'stent in a stent' technique was used for removal. This technique allows the safe removal of partially covered stents inserted following sleeve gastrectomy complications.

INTRODUCTION Gallstones are a common condition in bariatric patients after a laparoscopic Roux-en-Y gastric bypass (LRYGB). The management of ductal stones is challenging due to the altered gastrointestinal anatomy. Various techniques have been reported to manage bile duct stones. PRESENTATION OF CASE We present the successful percutaneous trans hepatic management of common bile duct stones after LRYGB. One year after a LRYGB for morbid obesity, a 59-year-old female presented with acute cholecystitis. One month after laparoscopic cholecystectomy a 1 cm calculus was found within the distal CBD and patient underwent a percutaneous trans hepatic cholangiography under local anesthetic. This involved a right sided anterior segmental duct puncture. With the sphincter dilated to 10 mm, a balloon catheter was used to push the stone into the duodenum leaving an internal- external drain. Patient recovered completely at follow up. DISCUSSION Patients with morbid obesity have a higher incidence of gallstones. After LRYGB, the altered anatomy does not allow the conventional endoscopic retrograde cholangiopancreatography (ERCP) for choledocholithiasis. Various techniques have been reported as means of managing bile duct stones in LRYGB patients. These include a double balloon enteroscope-assisted ERCP, laparoscopic transgastric ERCP, laparoscopic or open biliary surgery and interventional radiology. We report a non-surgical approach using percutaneous transhepatic technique under local anesthetic that resulted effective and could be applied more extensively. CONCLUSION Due to the increase of global obesity, bariatric centers need to strategically plan resources such as interventional radiology in order to manage post LRYGB choledocholithiasis safely, efficiently and in a cost effective manner.

Recently, a single-stapled technique (SST) was performed instead of the conventional double-stapled technique (DST) in laparoscopic low anterior resection for anastomosis, by placement of intracorporeal purse-string sutures on the distal rectum with transanal specimen extraction. This study aimed to compare the short-term outcomes between the two anastomotic techniques. Between July 2007 and April 2010, 60 patients underwent SST by laparoscopic or robotic procedure. These patients were matched 1:2 by age, gender, date of surgery, and tumor stage with 120 patients who underwent conventional DST in laparoscopic low anterior resection. The robotic-assisted operative approach was used more frequently in the SST group than in the DST group (61.7 % vs. 3.3 %, p < 0.001). The mean operative time was 203.9 (range, 120-400) min for the SST group and 167.6 (range, 90-300) min for the DST group (p < 0.001). For specimen removal, the transanal approach was used in the SST group, while the transabdominal approach was used for the DST group. The pain score (visual analogue scale) of the SST group was lower (4.5 vs. 5.6, p < 0.001), although postoperative recovery was similar. Pathological examination revealed that the distal resection margin was significantly longer in the SST group (3.1 vs. 2.5 cm, p = 0.018). Postoperative morbidity including anastomotic leakage was similar in both groups. SST yielded equivalent short-term outcomes when compared to conventional DST and provided the advantages of minimal access and a longer distal resection margin. Therefore, SST in lower anterior resection may be a useful alternative to conventional DST.

The relation between hunger, satiation, and integrated gastrointestinal motility and hormonal responses in morbidly obese patients after sleeve gastrectomy has not been determined. The objective was to assess the effects of sleeve gastrectomy on hunger, satiation, gastric and gallbladder motility, and gastrointestinal hormone response after a liquid meal test. Three groups were studied: morbidly obese patients (n = 16), morbidly obese patients who had had sleeve gastrectomy (n = 8), and nonobese patients (n = 16). The participants fasted for 10 h and then consumed a 200-mL liquid meal (400 kcal + 1.5 g paracetamol). Fasting and postprandial hunger, satiation, hormone concentrations, and gastric and gallbladder emptying were measured several times over 4 h. No differences were observed in hunger and satiation curves between morbidly obese and nonobese groups; however, sleeve gastrectomy patients were less hungry and more satiated than the other groups. Antrum area during fasting in morbidly obese patients was statistically significant larger than in the nonobese and sleeve gastrectomy groups. Gastric emptying was accelerated in the sleeve gastrectomy group compared with the other 2 groups (which had very similar results). Gallbladder emptying was similar in the 3 groups. Sleeve gastrectomy patients showed the lowest ghrelin concentrations and higher early postprandial cholecystokinin and glucagon-like peptide 1 peaks than did the other participants. This group also showed an improved insulin resistance pattern compared with morbidly obese patients. Sleeve gastrectomy seems to be associated with profound changes in gastrointestinal physiology that contribute to reducing hunger and increasing sensations of satiation. These changes include accelerated gastric emptying, enhanced postprandial cholecystokinin and glucagon-like peptide 1 concentrations, and reduced ghrelin release, which together may help patients lose weight and improve their glucose metabolism after

• To report our experience with retroperitoneal laparoscopic dismembered pyeloplasty for pelvi-ureteric junction (PUJ) obstruction in children. • Between March 2007 and December 2009, 38 children with PUJ obstruction (mean age 8.3 years, range 3-14) underwent retroperitoneal laparoscopic dismembered pyeloplasty. • A ureteric catheter was inserted into the mid-ureter cystoscopically. During pyeloplasty, the proximal end of the ureteric catheter was extracorporeally sutured to the distal end of the JJ stent with silk. • The ureteric catheter was then pulled down and the stent was pulled antegrade into the ureter and bladder. • The approach was retroperitoneal in all patients except one who required open conversion. The overall mean operative time was 162 min (range 145-210 min) and this appeared to decrease with experience. Mean hospital stay was 4 days (range 3-7 days). • Mean follow-up was 20.2 months (range 6-32 months). Satisfactory drainage with decreased hydronephrosis was documented in all patients on ultrasonography and intravenous urography. • Our study shows that retroperitoneal laparoscopic dismembered pyeloplasty is a feasible and effective alternative to open pyeloplasty with a relatively minimal complication rate in children 3 years of age and older, but it should be undertaken by experienced laparoscopic surgeons. © 2011 THE AUTHORS.

[Technical points of laparoscopic splenic hilar lymph node dissection--The original intention of CLASS-04 research design].

PubMed

Huang, Changming; Lin, Mi

2018-02-25

According to Japanese gastric cancer treatment guidelines, the standard operation for locally advanced upper third gastric cancer is the total gastrectomy with D2 lymphadenectomy, which includes the dissection of the splenic hilar lymph nodes. With the development of minimally invasive ideas and surgical techniques, laparoscopic spleen-preserving splenic hilar lymph node dissection is gradually accepted. It needs high technical requirements and should be carried out by surgeons with rich experience of open operation and skilled laparoscopic techniques. Based on being familiar with the anatomy of splenic hilum, we should choose a reasonable surgical approach and standardized operating procedure. A favorable left-sided approach is used to perform the laparoscopic spleen-preserving splenic hilar lymph node dissection in Department of Gastric Surgery, Fujian Medical University Union Hospital. This means that the membrane of the pancreas is separated at the superior border of the pancreatic tail in order to reach the posterior pancreatic space, revealing the end of the splenic vessels' trunk. The short gastric vessels are severed at their roots. This enables complete removal of the splenic hilar lymph nodes and stomach. At the same time, based on the rich clinical practice of laparoscopic gastric cancer surgery, we have summarized an effective operating procedure called Huang's three-step maneuver. The first step is the dissection of the lymph nodes in the inferior pole region of the spleen. The second step is the dissection of the lymph nodes in the trunk of splenic artery region. The third step is the dissection of the lymph nodes in the superior pole region of the spleen. It simplifies the procedure, reduces the difficulty of the operation, improves the efficiency of the operation, and ensures the safety of the operation.

We report a case of an epidermoid cyst within an intrapancreatic accessory spleen that was treated by laparoscopic excision. A 39-year-old man with no abdominal symptoms was incidentally found to have a cystic pancreatic lesion on computed tomography scan undertaken for suspected deep vein thrombosis. Further computed tomography and magnetic resonance imaging confirmed similar findings and the laparoscopic resection of the distal pancreas and spleen was undertaken as malignancy could not be excluded. Microscopic analysis revealed a well-circumscribed epidermoid cyst within a thin splenic rim in the tail of the pancreas. Such histologic diagnoses are extremely rare, and this is the 26th case report to our knowledge in English language journals. These lesions should be treated surgically to exclude malignancy. This is the first case reported in the United Kingdom and the first to be excised by pure laparoscopic means, which we believe provides effective and successful surgical management.

Whether adjuvant chemoradiotherapy may contribute to improve survival outcomes after D2-gastrectomy remains controversial. To explore the clinical utility of N-Ratio in selecting gastric cancer patients for adjuvant chemoradiotherapy after D2-gastrectomy. A retrospective cohort study was carried out on gastric cancer patients who underwent D2-gastrectomy alone or D2-gastrectomy plus adjuvant chemoradiotherapy (INT-0116 protocol) at the Hospital A. C. Camargo from September 1998 to December 2008. Statistical analysis were performed using multiple conventional methods, such as c-statistic, adjusted Cox's regression and stratified survival analysis. Our analysis involved 128 patients. According to c-statistic, the N-Ratio (i.e., as a continuous variable) presented "area under ROC curve" (AUC) of 0.713, while the number of metastatic nodes presented AUC of 0.705. After categorization, the cut-offs provide by Marchet et al. displayed the highest discriminating power - AUC value of 0.702. This N-Ratio categorization was confirmed as an independent predictor of survival using multivariate analyses. There also was a trend of better survival by adding of adjuvant chemoradiotherapy only for patients with milder degrees of lymphatic spread - 5-year survival of 23.1% vs 66.9%, respectively (HR = 0.426, 95% CI 0.150-1.202; P = 0.092). This study confirms the N-Ratio as a tool to improve the lymph node metastasis staging in gastric cancer and suggests the cut-offs provided by Marchet et al. as the best way for its categorization after a D2-gastrectomy. In these settings, the N-Ratio appears a useful tool to select patients for adjuvant chemoradiotherapy, and the benefit of adding this type of adjuvancy to D2-gastrectomy is suggested to be limited to patients with milder degrees of lymphatic spread (i.e., NR2, 10%-25%).

The aim of this study was to describe postoperative outcomes of total gastrectomy at our institution for patients with hereditary diffuse gastric cancer (HDGC). HDGC, which is mainly caused by germline mutations in the E-cadherin gene (CDH1), renders a lifetime risk of gastric cancer of up to 70%, prompting a recommendation for prophylactic total gastrectomy. A prospective gastric cancer database identified 41 patients with CDH1 mutation who underwent total gastrectomy during 2005 to 2015. Perioperative, histopathologic, and long-term data were collected. Of the 41 patients undergoing total gastrectomy, median age was 47 years (range 20 to 71). There were 14 men and 27 women, with 25 open operations and 16 minimally invasive operations. Median length of stay was 7 days (range 4 to 50). In total, 11 patients (27%) experienced a complication requiring intervention, and there was 1 peri-operative mortality (2.5%). Thirty-five patients (85%) demonstrated 1 or more foci of intramucosal signet ring cell gastric cancer in the examined specimen. At 16 months median follow-up, the median weight loss was 4.7 kg (15% of preoperative weight). By 6 to 12 months postoperatively, weight patterns stabilized. Overall outcome was reported to be "as expected" by 40% of patients and "better than expected" by 45%. Patient-reported outcomes were similar to those of other patients undergoing total gastrectomy. Total gastrectomy should be considered for all CDH1 mutation carriers because of the high risk of invasive diffuse-type gastric cancer and lack of reliable surveillance options. Although most patients have durable weight loss after total gastrectomy, weights stabilize at about 6 to 12 months postoperatively, and patients report outcomes as being good to better than their preoperative expectations. No patients have developed gastric cancer recurrence after resections.

[Closure of pancreas stump after distal and segmental resection : Suture, stapler, coverage or anastomosis?

Postoperative pancreatic fistulas represent the most frequent complication after distal and segmental pancreatectomy and occur with a frequency of up to 50 %. There are many technical variations of pancreatic stump treatment for reduction of fistula rates after distal resection. Most of these techniques have only been analyzed in retrospective studies and the evidence for or against a specific technique is low. Several retrospective trials have been conducted with good results to compare suturing with stapled closure of the remnant and to assess the effect of a vascularized falciform ligament patch in reducing postoperative pancreatic fistula; however, in a recently published randomized trial, which analyzed closure of the remnant with a pancreaticojejunostomy compared to standard closure, these results could not be confirmed. Because stapler resection and closure is the most commonly used technique in laparoscopic distal pancreatectomy, there are a large number of studies which assessed various novel methods of improving stapling. Extended stapler compression time and mesh augmentation of the stapler line can be valid methods to reduce fistula rates. Central pancreatectomy is a relatively rarely used procedure where the right-sided pancreatic remnant is closed in the same fashion as during distal pancreatectomy and the left-sided remnant is connected to the intestines with a pancreaticojejunostomy or pancreaticogastrostomy. In conclusion, postoperative pancreatic fistula rates are still a relevant clinical problem after distal pancreatectomy and further studies on potentially improved novel techniques are required.

The present study examined the effects of laparoscopic sleeve gastrectomy (LSG) on self-reported eating-related psychopathology and health-related quality of life (HRQoL). Outcomes of the LSG group were compared with a group of conservatively treated (CT) patients, who underwent a 1-year multimodal weight reduction group program that included dietary advice, physical exercise, psychoeducation, cognitive-behavioral therapy, training in Jacobson's progressive muscle relaxation, and social group support. The setting was a multidisciplinary obesity center. A sample of 103 patients with obesity were investigated using the Eating Disorder Inventory and the Short Form Health Survey before and, on average, 19 (±5) months after weight loss intervention. Thereof, 63 patients (age 45.6±10.9years, 71.4% females) underwent LSG, and 40 patients (age 50.6±11.3years, 77.5% females) underwent the CT program. Patients were assigned to either the surgical or the nonsurgical intervention group following clinical guidelines and patient preference. In the LSG group, excess weight loss (%EWL) was 53.0±24.0%, and body mass index (BMI) decreased from 51.5±8.1 to 38.0±7.7kg/m 2 . In the CT group, %EWL was 13.9±27.1%, and BMI decreased from 40.3±6.7 to 38.0±7.2kg/m 2 . Significant improvements in eating-related psychopathology were observed in both groups. Although both groups had a similar BMI after the respective interventions, LSG patients reported significantly greater body satisfaction and substantial improvement in perceived physical health from a lower baseline level than CT patients. In the second follow-up year, LSG was associated with greater weight loss from a higher baseline weight, and greater improvements in self-reported eating-related psychopathology and physical HRQoL compared with conservative treatment.

Exogenous glutamine supplement is known to improve morbidity and mortality of critically-ill patients. This study was conducted to elucidate the role of glutamine in minimally invasive surgery. We retrospectively reviewed subtotal gastrectomy patients in National Taiwan University Hospital from Dec 2005 to Dec 2008. The patients were divided into three groups. Group 1 underwent subtotal gastrectomy by laparotomy without glutamine supplement, group 2 underwent subtotal gastrectomy by laparotomy with glutamine supplement and group 3 underwent gasless laparoscopy-assisted subtotal gastrectomy with parenteral glutamine supplement. There were 155 patients in total; 85 patients in group 1, 17 in group 2 and 53 in group 3. The mean flatus days after operation are 3.6, 3.1 and 2.8 for groups 1, 2 and 3, respectively (p=0.001). Oral intake after operation was commenced after 6.7, 5.0 and 4.7 days (p=0.006). The body temperature had borderline differences between groups 3 and 1. There were significant differences in postoperative systemic responses including heart rates (p<0.001) and tenderness (p=0.011) 5 days after operation for group 3 vs. group 1. Minimally invasive surgery was a negative factor for postoperative body temperature change. Glutamine was a significant factor for postoperative heart rate change and reduction of tenderness. Glutamine supplement may have synergic effects of rapid recovery in minimal invasive surgery for subtotal gastrectomy patients by minimizing the postoperative systemic response and accelerating recovery.

IMPORTANCE Evidence about the efficacy of laparoscopic resection of rectal cancer is incomplete, particularly for patients with more advanced-stage disease. OBJECTIVE To determine whether laparoscopic resection is noninferior to open resection, as determined by gross pathologic and histologic evaluation of the resected proctectomy specimen. DESIGN, SETTING, AND PARTICIPANTS A multicenter, balanced, noninferiority, randomized trial enrolled patients between October 2008 and September 2013. The trial was conducted by credentialed surgeons from 35 institutions in the United States and Canada. A total of 486 patients with clinical stage II or III rectal cancer within 12 cm of the anal verge were randomized after completion of neoadjuvant therapy to laparoscopic or open resection. INTERVENTIONS Standard laparoscopic and open approaches were performed by the credentialed surgeons. MAIN OUTCOMES AND MEASURES The primary outcome assessing efficacy was a composite of circumferential radial margin greater than 1 mm, distal margin without tumor, and completeness of total mesorectal excision. A 6%noninferiority margin was chosen according to clinical relevance estimation. RESULTS Two hundred forty patients with laparoscopic resection and 222 with open resection were evaluable for analysis of the 486 enrolled. Successful resection occurred in 81.7%of laparoscopic resection cases (95%CI, 76.8%–86.6%) and 86.9%of open resection cases (95%CI, 82.5%–91.4%) and did not support noninferiority (difference, −5.3%; 1-sided 95%CI, −10.8%to ∞; P for noninferiority = .41). Patients underwent low anterior resection (76.7%) or abdominoperineal resection (23.3%). Conversion to open resection occurred in 11.3%of patients. Operative time was significantly longer for laparoscopic resection (mean, 266.2 vs 220.6 minutes; mean difference, 45.5 minutes; 95%CI, 27.7–63.4; P < .001). Length of stay (7.3 vs 7.0 days; mean difference, 0.3 days; 95%CI, −0.6 to 1.1), readmission within 30

The laparoscopic surgery has gained presence in the operating room in cases where it is feasible to spare patient trauma and minimize the hospital stay. One unique challenge in laparoscopic/endoscopic surgery is operating and removing tissue volume through keyhole - trocar. The removal of tissues by fragmentation is generally termed morcellation. We proposed a new method for soft tissue morcellation using laparoscopy. A unique ultrasonic laparoscopic surgical device, termed Laparosound{trade mark, serif}, utilizing laparoscopic high amplitude ultrasonic waveguides, operating in edge mode, has been developed that uses the principle of ultrasonic cavitation phenomenon for excision and morcellation of a variety of tissue types. The local ultrasonic acoustic intensity at the distal waveguide tip is sufficiently high that the liquefaction of moist tissue occurs. The mechanism of tissue morcellation is deemed to be cavitation based, therefore is dependant on water content in tissue, and thus its effectiveness depends on tissue type. This results in ultrasound being efficient in moist tissue and sparing dry, collagen rich blood vessels and thus minimizes bleeding. The applications of such device in particular, commonly encountered, could lay in general and ob/gyn laparoscopic surgery, whereas other applications could emerge. The design of power ultrasonic instruments for mass clinical applications poses however unique challenges, such as ability to design and build ultrasonic resonators that last in conditions of ultrasonic fatigue. These highly non-linear devices, whose behavior is hard to predict, have become the challenge of the author of the present paper. The object of work is to design and build an operating device capable of ultrasonic soft tissue morcellation in laparoscopic surgery. This includes heavy computational ultrasonics verified by testing and manufacturing feasibility using titanium biomedical alloys. The prototype Laparosound{trade mark, serif} device

Gallstones are a common condition in bariatric patients after a laparoscopic Roux-en-Y gastric bypass (LRYGB). The management of ductal stones is challenging due to the altered gastrointestinal anatomy. Various techniques have been reported to manage bile duct stones. We present the successful percutaneous trans hepatic management of common bile duct stones after LRYGB. One year after a LRYGB for morbid obesity, a 59-year-old female presented with acute cholecystitis. One month after laparoscopic cholecystectomy a 1cm calculus was found within the distal CBD and patient underwent a percutaneous trans hepatic cholangiography under local anesthetic. This involved a right sided anterior segmental duct puncture. With the sphincter dilated to 10mm, a balloon catheter was used to push the stone into the duodenum leaving an internal- external drain. Patient recovered completely at follow up. Patients with morbid obesity have a higher incidence of gallstones. After LRYGB, the altered anatomy does not allow the conventional endoscopic retrograde cholangiopancreatography (ERCP) for choledocholithiasis. Various techniques have been reported as means of managing bile duct stones in LRYGB patients. These include a double balloon enteroscope-assisted ERCP, laparoscopic transgastric ERCP, laparoscopic or open biliary surgery and interventional radiology. We report a non-surgical approach using percutaneous transhepatic technique under local anesthetic that resulted effective and could be applied more extensively. Due to the increase of global obesity, bariatric centers need to strategically plan resources such as interventional radiology in order to manage post LRYGB choledocholithiasis safely, efficiently and in a cost effective manner.

A good operative field is important for safe operations, but it is sometimes difficult to obtain a satisfactory operative field in laparoscopic upper abdominal surgery. We developed a novel and safe technique for the retraction of the liver and falciform ligament during laparoscopic surgery, and evaluated its technical feasibility and safety. Forty-three patients with gastric cancer were divided into two groups: disk suspension group (DS group; snake retractor and elastic band fixation with a silicon disk), and fixed retractor group (FR group; snake retractor and nonelastic band fixation without a silicon disk). To evaluate liver damage during retraction, we measured the aspartate aminotransferase (AST) and alanine aminotransferase (ALT) levels preoperatively and on postoperative day (POD) 1. In the DS group, all liver lobes were adequately retracted and the hepatoduodenal and gastrohepatic ligaments were fully exposed. This procedure took less than 3 min. On the other hand, 5 of 18 patients of the FR group had insufficient surgical fields for laparoscopic gastrectomy because of soft and/or large livers. Although the preoperative AST and ALT levels were not different between the two groups, the DS group did not display increases in both AST and ALT levels, whereas the FR group showed increases in both on POD 1 (AST: 50.2 ± 8.4 IU/l vs. 124.2 ± 37.7 IU/l, P = 0.07; and ALT: 35.6 ± 6.4 IU/l vs. 106.1 ± 36.2 IU/l, P = 0.07). No complications related to the liver retraction were observed in the DS group. However, liver congestion was evident in six patients and minor liver injury in two patients of the FR group during the esophagojejunostomy. The DS method is a simple and safe and provides a better surgical field during laparoscopic surgery of the upper abdomen without damaging the liver.

The use of robotic platforms in bariatric surgery has recently gained relevance. With an increased use of this technology come concerns regarding learning curve effects during the initial implementation phase. The sleeve gastrectomy though may represent an ideal training procedure for introducing the robot into bariatric surgical practice. The present review of the first 10 consecutive robotic sleeve gastrectomy procedures performed in an Australian bariatric programme by a single surgeon describes the evolution of the technique, learning curve and initial patient outcomes. Between 2014 and 2015, robotic sleeve gastrectomies were performed as primary and revisional procedures by a consistent surgeon-assistant team. Technique evolution and theatre set-up were documented. Patient demographics, operative time (robot docking and total operation time), additional operative procedures performed, operative and post-operative complications at 1, 3 and 6 months post-procedure and weight loss achieved at 6 months were retrospectively reviewed from a prospectively maintained database. Ten robotic sleeve gastrectomies were performed without significant operative complications. One patient was treated as an outpatient with oral antibiotics for a superficial wound infection. The median total operative time was 123 min (interquartile range (IQR) 108.8-142.5), with a median incision to docking time of 19 min (IQR 15.0-31.8). Length of stay in hospital was 2-3 days. Median excess weight loss achieved at 6 months was 50% (IQR 33.9-66.5). This study describes a method of safely introducing the da Vinci robot into bariatric surgical practice. © 2016 Royal Australasian College of Surgeons.

Toxic nitrite and N-nitroso compounds due to gastric bacterial growth are often detected in the stomach of patients with atrophic gastritis and partial gastrectomy. The aim of this study is to investigate whether breath N2O, a major metabolite of denitrification, detected after ingestion of nitrate is associated with atrophic gastritis and partial gastrectomy. Nine young, 16 normal older, nine atrophic gastritis and six partial gastrectomy subjects ingested 100 g lettuce, equal to 130 mg nitrate, and breath N2O was measured at 15-min intervals for 5 h. N2O was analyzed using an infrared-photoacoustic analyzer, and atrophic gastritis was diagnosed by pepsinogen test. The mean breath N2O concentrations were higher in the following order at all times: partial gastrectomy>atrophic gastritis>normal>young. The maximum N2O concentrations in the patients with partial gastrectomy and atrophic gastritis were 1655 +/- 296 and 1350 +/- 200 (mean +/- S.E.) ppb, respectively, which were higher than that of the normal subjects, 827 +/- 91 ppb (P < 0.05). The maximum N2O concentration in young people was 527 +/- 86 ppb, which was lower than that of the normal older people (P < 0.051). These higher N2O concentrations in gastric patients reflect bacterial growth in the stomach due to the reduction of gastric acid. Copyright 2004 Elsevier B.V.

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

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

Aims To investigate the feasibility and safety of endoscopic submucosal dissection (ESD) of gastric epithelial neoplasms in the remnant stomach (GEN-RS) after various types of partial gastrectomy. Methods This study included 29 patients (31 lesions) who underwent ESD for GEN-RS between March 2006 and August 2016. Clinicopathologic data were retrieved retrospectively to assess the therapeutic ESD outcomes, including en bloc and complete resection rates and procedure-related adverse events. Results The en bloc, complete, and curative resection rates were 90%, 77%, and 71%, respectively. The types of previous gastrectomy, tumor size, macroscopic type, and tumor histology were not associated with incomplete resection. Only tumors involving the suture lines from the prior partial gastrectomy were significantly associated with incomplete resection. The procedure-related bleeding and perforation rates were 6% and 3%, respectively; none of the adverse events required surgical intervention. During a median follow-up period of 25 months (range, 6–58 months), there was no recurrence in any case. Conclusions ESD is a safe and feasible treatment for GEN-RS regardless of the previous gastrectomy type. However, the complete resection rate decreases for lesions involving the suture lines.

The esophago-gastric junction may be challenging during total gastrectomy due to gastric cancer. This situation may compromise the security of both the dissection and anastomosis. The purpose of this study was to investigate the usefulness of xiphoidectomy to overcome this issue. The files of patients who underwent total gastrectomy + D2 lymph node dissection due to proximal gastric cancer or cardia cancer between April 2002-December 2013 were retrospectively evaluated. We assessed the outcome in patients with xiphoidectomy in addition to the midline incision in terms of xiphoidectomy technique, xiphoidectomy time, and operative and postoperative complications. Thirty cases were identified to undergo xiphoidectomy. Nineteen patients were male and 11 were female, with a mean age of 51 (21-80) years. The time required for xiphoidectomy was 7-15 minutes (mean 8.7 minutes). The mean additional time required for the closure of the incision in cases with xiphoidectomy was 2 minutes. There was minimal arterial bleeding from the diaphragmatic surface in one patient, which was controlled by electrocautery. Only two patients developed wound infection. Performing xiphoidectomy is quite easy, after a certain learning phase. The operative time was 7-15 minutes longer due to excision of xiphoid and closure of the related defect. Minor hemorrhage was a problem during surgery. There were no early or late post-operative complications. We suggest that the procedure is beneficial in selected cases with requirement of a wider operative field or better exposure of the esophago-gastric junction during total gastrectomy for gastric cancer, and recommend removal of the xiphoid bone.

Gastric cancer is one of the most frequent causes of death secondary to cancer in the world. Surgery is the only potentially curative treatment but its clinical consequences are significant. The objective of this study is to evaluate the nutritional state of patients with a total gastrectomy secondary to gastric adenocarcinoma. We designed a descriptive study with a transversal cut in our institution. We included 22 patients which had a minimum evolution time of six months after total gastrectomy secondary to gastric cancer surgery was performed. Neither of them had metastasis. The nutritional analysis included only biochemical data. Descriptive statistics were used for statistical analysis. Eight females and 14 males were included in the study. Median age was 57 years (34 - 69 years). The 74% of the patients were underweight and none of them was overweight. The average body mass index (BMI) was 16.88 kg/m 2 . Eleven patients suffered from mild anemia (10.5 - 12 g/dl) and 5 from moderate anemia (9 - 10.5 g/dl). Only two patients presented severe anemia (less than 9 g/dl). The 58% presented hypoproteinaemia and hypoalbuminaemia. The main post-surgery complication was nausea (46%). Seventy-eight percent of the patients had loss of appetite. Twenty-one patients were able to walk without help and leave their homes. The incidence of anemia in these patients was very high. In most of the patients, albumin and proteins levels were affected too. So malnutrition was a relevant consequence of a total gastrectomy.

Although long-term results of sleeve gastrectomy (LSG) remain scarce in the literature, its popularity as a stand-alone procedure has accounted for a global increase in LSG performance. In this retrospective study, the authors present 5 to 8-year follow-up results in terms of weight loss, failure/revision rate, and comorbidity resolution from a single center. A prospectively maintained database was reviewed for patients who underwent LSG between 2007 and 2010. Data analysis on weight loss, comorbid conditions, revision surgery, and mortality was conducted. Median percentage excess BMI loss (%EBMIL) was 59.0, and 53.9 %, and median percentage total weight loss (%TWL) was 25.1, and 22.9 % at 5 and 8 years, respectively. Revision to gastric bypass due to insufficient weight loss or gastroesophageal reflux disease (GERD) was performed in 42 patients (15.2 %). Resolution of comorbid condition was achieved in 91 % of patients with obstructive sleep apnea syndrome (OSAS), 68 % of patients with type 2 diabetes (T2DM), 53 % of patients with hypertension, and 25 % of patients with dyslipedemia. Loss to follow-up rate was 45 % at 5 years, 28 % at 6 years, 23 % at 7 years, and 13 % at 8 years. This study adds to the currently available data confirming the LSG to be a safe and effective procedure at long term. Data from high-volume studies are needed to establish the definite role of the LSG in the spectrum of bariatric procedures.

Laparoscopic Heller myotomy for achalasia: changing trend toward "true" day-case procedure.

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

To assess the extent of gastric intestinal metaplasia (IM) in gastrectomy specimens in populations of the Pacific basin having different incidence of gastric carcinoma. One thousand three hundred and nine-two gastrectomies were investigated: 1088 had a gastric carcinoma and 304 miscellaneous gastric diseases. Twenty-one thousand three hundred and fourteen histological sections were reviewed under low-power (4X). IM was either spotty (SIM) or extended (EIM= encompassing one or more entire low-power fields/section). Widespread IM (WIM) was regarded as EIM if present in > or =5 histological sections. The percent of gastrectomies harboring a carcinoma increased significantly with increasing age more notably in those with diffuse carcinomas (DC) than in those with intestinal carcinomas (IC). The percent of gastrectomies with EIM was significantly higher in specimens with IC than with DC, particularly among elderly patients, and in specimens from countries with a high cancer incidence. The percent of gastrectomies with WIM was higher in specimens having IC than in those having DC. Migration per se did not influence the frequency of specimens with EIM in elderly Japanese patients: Japanese migrants to Hawaii had a similarly high frequency of EIM as those dwelling in Japan. Japanese patients with a gastric carcinoma showed atypical mitoses in areas with EIM far from the tumor, suggesting that cellular mutation(s) play a role in the evolution of EIM towards gastric dysplasia and carcinoma in that ethnic group. The drawback of gastric biopsies in assessing the extent of gastric intestinal metaplasia and, thereby, estimating possible cancer risk in long-term studies has been stressed.

Of this study was to evaluate the treatment of common bile duct stones (CBDS) by laparoscopic choledochoscopy. Between 1997-2002, 9 patients (with age between 42-75 years) were treated laparoscopic for CBDS: 8 cases with choledocholithiasis; 1 case with pancreatic neoplasm. Laparoscopic choledochoscopy was performed in 7 cases (84.4%). We used the choledochoscope Pentax of 5 mm diameter and with work canal. We performed the CBD exploration with: transcystic approach-1 case; choledochotomy-6 cases. The CBD diameter was between 1.2-1.5 cm. The bile duct stones diameter were between 0.5-1.5 cm. We performed with successfully the laparoscopic choledochoscopy exploration and extraction of CBD stones to all patients. External biliary drainage (transcystic duct and with Kehr-tube) were done systematically. The major complication (choleperitoneum) occurred in 2 cases (28.5%). The occurrence of residual ductal stones was 0. The laparoscopic treatment of choledocholithiasis is feasible, safe and efficient.

To assess the clinical significance of pouch size in total gastrectomy for gastric malignancies. We manually searched the English-language literature in PubMed, Cochrane Library, Web of Science and BIOSIS Previews up to October 31, 2013. Only randomized control trials comparing small pouch with large pouch in gastric reconstruction after total gastrectomy were eligible for inclusion. Two reviewers independently carried out the literature search, study selection, data extraction and quality assessment of included publications. Standard mean difference (SMD) or relative risk (RR) and corresponding 95%CI were calculated as summary measures of effects. Five RCTs published between 1996 and 2011 comparing small pouch formation with large pouch formation after total gastrectomy were included. Eating capacity per meal in patients with a small pouch was significantly higher than that in patients with a large pouch (SMD = 0.85, 95%CI: 0.25-1.44, I(2) = 0, P = 0.792), and the operative time spent in the small pouch group was significantly longer than that in the large pouch group [SMD = -3.87, 95%CI: -7.68-(-0.09), I (2) = 95.6%, P = 0]. There were no significant differences in body weight at 3 mo (SMD = 1.45, 95%CI: -4.24-7.15, I(2) = 97.7%, P = 0) or 12 mo (SMD = -1.34, 95%CI: -3.67-0.99, I(2) = 94.2%, P = 0) after gastrectomy, and no significant improvement of post-gastrectomy symptoms (heartburn, RR = 0.39, 95%CI: 0.12-1.29, I(2) = 0, P = 0.386; dysphagia, RR = 0.86, 95%CI: 0.58-1.27, I(2) = 0, P = 0.435; and vomiting, RR = 0.5, 95%CI: 0.15-1.62, I(2) = 0, P = 0.981) between the two groups. Small pouch can significantly improve the eating capacity per meal after surgery, and may improve the post-gastrectomy symptoms, including heartburn, dysphagia and vomiting.

Although the extent of resection frequently dictates the method of reconstruction following distal subtotal gastrectomy, it is unclear whether Roux-en-Y gastrojejunostomy compared with Billroth II gastrojejunostomy is associated with superior perioperative outcomes. Patients who underwent resection for gastric cancer with Roux-en-Y or Billroth II reconstruction between 2000 and 2012 in seven academic institutions (US Gastric Cancer Collaborative) were identified. Patients who underwent total gastrectomy, gastric wedge, or palliative resections (metastatic disease or R2 resections) were excluded. Of a total of 965 patients, 447 met the inclusion criteria. A comparison between the Roux-en-Y (n = 257) and Billroth II (n = 190) groups demonstrated no differences in patient and tumor characteristics, except for Billroth II patients having a higher proportion of antral tumors (71 % vs. 50 %, p < 0.001). Roux-en-Y operations were slightly longer (244 min vs. 212 min, p < 0.001) and associated with somewhat higher blood loss (243 ml vs. 205 ml, p = 0.033). However, there were no significant differences in the length of hospital stay (8 days vs. 7 days), readmission rate (17 % vs. 18 %), 90-day mortality (5.1 % vs. 4.7 %), incidence (39 % vs. 41 %) and severity of complications, dependency on jejunostomy tube feeding at discharge (13 % vs. 12 %), same-patient decrease in serum albumin level from the preoperative to the postoperative value at 30, 60, and 90 days, receipt of adjuvant therapy (50 % vs. 53 %), or 5-year survival (44 % vs. 41 %). Although long-term quality-of-life parameters were not compared, this study did not show an advantage of Roux-en-Y gastrojejunostomy over Billroth II gastrojejunostomy in short-term perioperative outcomes. Both techniques should be regarded as equally acceptable reconstructive options following partial gastrectomy for gastric cancer.

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

Simulation System for Training in Laparoscopic Surgery

A computer-based simulation system creates a visual and haptic virtual environment for training a medical practitioner in laparoscopic surgery. Heretofore, it has been common practice to perform training in partial laparoscopic surgical procedures by use of a laparoscopic training box that encloses a pair of laparoscopic tools, objects to be manipulated by the tools, and an endoscopic video camera. However, the surgical procedures simulated by use of a training box are usually poor imitations of the actual ones. The present computer-based system improves training by presenting a more realistic simulated environment to the trainee. The system includes a computer monitor that displays a real-time image of the affected interior region of the patient, showing laparoscopic instruments interacting with organs and tissues, as would be viewed by use of an endoscopic video camera and displayed to a surgeon during a laparoscopic operation. The system also includes laparoscopic tools that the trainee manipulates while observing the image on the computer monitor (see figure). The instrumentation on the tools consists of (1) position and orientation sensors that provide input data for the simulation and (2) actuators that provide force feedback to simulate the contact forces between the tools and tissues. The simulation software includes components that model the geometries of surgical tools, components that model the geometries and physical behaviors of soft tissues, and components that detect collisions between them. Using the measured positions and orientations of the tools, the software detects whether they are in contact with tissues. In the event of contact, the deformations of the tissues and contact forces are computed by use of the geometric and physical models. The image on the computer screen shows tissues deformed accordingly, while the actuators apply the corresponding forces to the distal ends of the tools. For the purpose of demonstration, the system has been set

Gastrogastric Fistula: an Unusual Cause for Severe Bile Reflux Following Conversion of Sleeve Gastrectomy to One Anastomosis Gastric Bypass.

Haddad, Ashraf; Bashir, Ahmad; Nimeri, Abdelrahman

2018-05-04

One anastomosis gastric bypass/mini-gastric bypass (OAGB/MGB) was first described in 2001 as a safe and effective procedure. It has been gaining popularity worldwide. Multiple authors have reported the need to re-operate on patients for bile reflux. We report a patient with severe bile reflux after laparoscopic conversion of sleeve gastrectomy (LSG) to OAGB/MGB. A 33-year-old patient underwent a LSG in 2014. Postoperatively, she developed severe gastroesophageal acid reflux. In 2016, she underwent conversion of LSG to OAGB/MGB at the original institution for the treatment of her reflux symptoms. In 2017, she presented to us with epigastric pain, worsening reflux symptoms, steatorrhea, hypoproteinemia (6 g/dl), and body mass index of 25 kg/m 2 . Preoperative endoscopy revealed bile reflux, suture bezoar, and ulceration at the anastomosis. Laparoscopic exploration started by identifying the anatomy and measuring the lengths of the biliopancreatic limb (350 cm) and the common channel (450 cm). Upon dissecting the pouch, a gastrogastric fistula extending from the antrum to the pouch was encountered. This was confirmed with intraoperative endoscopy with bile refluxing to the pouch. The fistula, antrum, and part of the pouch were resected. The patient was converted to Roux-en-Y gastric bypass. She had an uneventful postoperative recovery. At 3 months of follow-up, her weight was stable and her steatorrhea resolved. Patients with bile reflux after OAGB/MGB need a high index of suspicion to detect unusual causes. Gastrogastric fistula is an unusual etiology of bile reflux that was never reported in the literature previously.

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

Results: Thirty cases were identified to undergo xiphoidectomy. Nineteen patients were male and 11 were female, with a mean age of 51 (21–80) years. The time required for xiphoidectomy was 7–15 minutes (mean 8.7 minutes). The mean additional time required for the closure of the incision in cases with xiphoidectomy was 2 minutes. There was minimal arterial bleeding from the diaphragmatic surface in one patient, which was controlled by electrocautery. Only two patients developed wound infection. Conclusion: Performing xiphoidectomy is quite easy, after a certain learning phase. The operative time was 7–15 minutes longer due to excision of xiphoid and closure of the related defect. Minor hemorrhage was a problem during surgery. There were no early or late post-operative complications. We suggest that the procedure is beneficial in selected cases with requirement of a wider operative field or better exposure of the esophago-gastric junction during total gastrectomy for gastric cancer, and recommend removal of the xiphoid bone PMID:26985158

The purpose of the review was to evaluate the feasibility and outcome of laparoscopic pancreatic cystogastrostomy for operative drainage of symptomatic pancreatic pseudocysts. A retrospective review of all patients who underwent laparoscopic pancreatic cystogastrostomy between June 1997 and July 2001 was performed. Data regarding etiology of pancreatitis, size of pseudocyst, operative time, complications, and pseudocyst recurrence were collected and reported as median values with ranges. Laparoscopic pancreatic cystogastrostomy was attempted in 6 patients. Pseudocyst etiology included gallstone pancreatitis (3), alcohol-induced pancreatitis (2), and post-ERCP pancreatitis (1). The cystogastrostomy was successfully performed laparoscopically in 5 of 6 patients. However, the procedure was converted to open after creation of the cystgastrostomy in 1 of these patients. There were no complications in the cases completed laparoscopically and no deaths in the entire group. No pseudocyst recurrences were observed with a median followup of 44 months (range 4-59 months). Laparoscopic pancreatic cystgastrostomy is a feasible surgical treatment of pancreatic pseudocysts with a resultant low pseudocyst recurrence rate, length of stay, and low morbidity and mortality.

Esophageal reflux symptom has been reported as common in patients with subtotal gastrectomy. Management of postoperative esophageal reflux symptom is not satisfactory. The aim of this study is to investigate prevalence of esophageal reflux symptom after subtotal gastrectomy and assess factors affecting esophageal reflux symptom in subtotal gastrectomy patients. We prospectively enrolled 100 consecutive patients with subtotal gastrectomy who were regularly followed up by endoscopic examination. Acid secretory capacity was assessed by measuring messenger RNA (mRNA) expression of H + /K + -adenosine triphosphatase (ATPase) via real-time polymerase chain reaction (PCR) in biopsy specimens. In total, 47 % of patients had typical esophageal reflux symptom, where heartburn or regurgitation was experienced at least weekly. Age, sex, body mass index, and type of reconstruction did not differ between esophageal reflux and non-esophageal-reflux groups. The esophageal reflux group had longer duration from time of operation until study (median 5.0 versus 3.6 years; P = 0.017). Hill grade for gastroesophageal (GE) flap valve was higher in the esophageal reflux group than in the non-esophageal-reflux group (P = 0.027). H + /K + -ATPase mRNA expression was higher in the esophageal reflux group than in the non-esophageal-reflux group [3967.6 (± 7583.7) versus 896.2 (± 1456.0); P = 0.006]. Multivariate analysis revealed that postoperative duration, H + /K + -ATPase mRNA expression level, and GE flap valve disruption were significantly associated with esophageal reflux symptom development. Esophageal reflux symptom is common in patients after subtotal gastrectomy, possibly because of anti-reflux-barrier impairment and preservation of acid secretory capacity following surgery. Optimal acid suppression may be helpful in managing postoperative esophageal reflux symptom.

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

Postoperative complications are associated with increased hospital costs following major surgery, but the mechanism by which they increase cost and the categories of care that drive this increase are poorly described. To describe the association of postoperative complications with hospital costs following total gastrectomy for gastric adenocarcinoma. This retrospective analysis of a prospectively collected gastric cancer surgery database at a single National Cancer Institute-designated comprehensive cancer center included all patients undergoing curative-intent total gastrectomy for gastric adenocarcinoma between January 2009 and December 2012 and was conducted in 2015 and 2016. Ninety-day normalized postoperative costs. Hospital accounting system costs were normalized to reflect Medicare reimbursement levels using the ratio of hospital costs to Medicare reimbursement and categorized into major cost categories. Differences between costs in Medicare proportional dollars (MP $) can be interpreted as the amount that would be reimbursed to an average hospital by Medicare if it paid differentially based on types and extent of postoperative complications. In total, 120 patients underwent curative-intent total gastrectomy for stage I through III gastric adenocarcinoma between 2009 and 2012. Of these, 79 patients (65.8%) were men, and the median (interquartile range) age was 64 (52-70) years. The 51 patients (42.5%) who underwent an uncomplicated total gastrectomy had a mean (SD) normalized cost of MP $12 330 (MP $2500), predominantly owing to the cost of surgical care (mean [SD] cost, MP $6830 [MP $1600]). The 34 patients (28.3%) who had a major complication had a mean (SD) normalized cost of MP $37 700 (MP $28 090). Surgical care was more expensive in these patients (mean [SD] cost, MP $8970 [MP $2750]) but was a smaller contributor to total cost (24%) owing to increased costs from room and board (mean [SD] cost, MP $11 940 [MP $8820]), consultations (mean [SD

Functional jejunal interposition (FJI) has been applied as a reconstruction procedure to maintain the jejunal continuity and duodenal food passage after total gastrectomy in patients with gastric cancer. The purpose of this study was to evaluate clinical efficacy of the FJI procedure by comparing the functional outcomes of FJI to Roux-en-Y after total gastrectomy in gastric cancer patients, and investigate physiologic mechanisms by which FJI exerts beneficial outcomes in beagles. Patients with stage I-IV gastric cancer without metastasis and recurrence one year after surgery were enrolled in this retrospective study. Seventy one patients received FJI and seventy nine patients received Roux-en-Y after total gastrectomy. We evaluated the nutritional status at three and twelve months and incidence of complications up to twelve months after surgery. Beagles receiving sham operation, FJI, or Roux-en-Y after total gastrectomy were sacrificed forty eight hours postoperatively. Beagles were gavaged with active carbon for evaluating the intestinal transit rate. Intestinal tissues from the duodenojejunal anastomosis were collected for examining interstitial cells of Cajal (ICC), inflammation, and apoptosis. Compared to the bodyweight before surgery, the bodyweight loss at three and twelve months after surgery in patients receiving FJI was significant less than that in patients with Roux-en-Y. Patients with the FJI procedure showed significant increase of blood hemoglobin and total protein, compared to those at one month after surgery, and the prognostic nutrition index scores at three and twelve months after surgery. The incidence rates of post-operative complications, including reflux esophagitis, dumping syndrome, and Roux-en-Y syndrome were decreased in patients with FJI. Compared to beagles receiving Roux-en-Y, more ICC in the intestinal submuocsa, less intestinal epithelial cell apoptosis, and decreased inflammation in serosal side of the intestine were found in the FJI

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

Aim. To investigate and compare the efficiency of two appliances for molar distalization: the bone-anchored distal screw (DS) and the traditional tooth-supported distal jet (DJ) for molar distalization and anchorage loss. Methods. Tests (18 subjects) were treated with a DS and controls (18 subjects) were treated with a DJ. Lateral cephalograms were obtained before and at the end of molar distalization and were analysed. Shapiro Wilk test, unpaired t-test, and Wilcoxon rank-sum test were applied according to values distribution. The α level was fixed at 0.05. Results. Maxillary first molars were successfully distalized into a Class I relationship in all patients. The mean molar distalization and treatment time were similar in both groups. The DS group exhibited a spontaneous distalization (2.1 ± 0.9 mm) of the first premolar with control of anchorage loss, distal tipping, extrusion, and skeletal changes. Conclusions. The DS is an adequate compliance-free distalizing appliance that can be used safely for the correction of Class II malocclusions. In comparison to the traditional DJ, the DS enables not only a good rate of molar distalization, but also a spontaneous distalization of the first premolars. PMID:25018770

Summary It is still controversial whether patients with a history of gastrectomy have high risk of esophageal carcinogenesis. On the other hand, the treatment strategy for esophageal cancer patients after gastrectomy is complicated. The association between histories of gastrectomy and esophageal carcinogenesis was retrospectively analyzed, and the treatment of esophageal cancer patients after gastrectomy was evaluated based on questionnaire data collected from multiple centers in Kyushu, Japan. The initial subject population comprised 205 esophageal cancer patients after gastrectomy. Among them, 108 patients underwent curative surgical treatment, and 70 patients underwent chemoradiation therapy (CRT). The time between gastrectomy and esophageal cancer development was longer in peptic ulcer patients (28.3 years) than in gastric cancer patients (9.6 years). There were no differences in the location of esophageal cancer according to the gastrectomy reconstruction method. There were no significant differences in the clinical background characteristics between patients with and without a history of gastrectomy. Among the 108 patients in the surgery group, the 5‐year overall survival rates for stages I (n = 30), II (n = 18), and III (n = 60) were 68.2%, 62.9%, and 32.1%, respectively. In the CRT group, the 5‐year overall survival rate of stage I (n = 29) was 82.6%, but there were no 5‐year survivors in other stages. The 5‐year overall survival rate of patients with CR (n = 33) or salvage surgery (n = 10) was 61.2% or 36%, respectively. For the treatment of gastrectomized esophageal cancer patients, surgery or CRT is recommended for stage I, and surgery with or without adjuvant therapy is the main central treatment in advanced stages, with surgery for stage II, neoadjuvant therapy + surgery for stage III, and CRT + salvage surgery for any stage, if the patient's condition permits.

When performing a laparoscopic assisted gastrectomy, a function-preserving gastrectomy is performed depending on the location of the primary gastric cancer. This study examined the incidence of lymph node metastasis by the lymph node station number by tumor location to determine the optimal extent of the lymph node dissection. The subjects consisted of 1,510 patients diagnosed with gastric cancer who underwent a gastrectomy between 1996 and 2005. The patients were divided into three groups: upper, middle and lower third, depending on the location of the primary tumor. The lymph node metastasis patterns were analyzed in the total and early gastric cancer patients. In all patients, lymph node station numbers 1, 2, 3, 7, 10 and 11 metastases were dominant in the cancer originating in the upper third, whereas station numbers 4, 5, 6 and 8 were dominant in the lower third. In early gastric cancer patients, the station number of lymph nodes with a metastasis did not show a significant difference in stage pT1a disease. On the other hand, a metastasis in lymph node station number 6 was dominant in stage pT1b disease that originated in the lower third of the stomach. When performing a laparoscopic-assisted gastrectomy for early gastric cancer, a limited lymphadenectomy is considered adequate during a function-preserving gastrectomy in mucosal (T1a) cancer. On the other hand, for submucosal (T1b) cancer, a number 6 node dissection should be performed when performing a pylorus preserving gastrectomy.

The Centers for Medicare & Medicaid Services (CMS) recently released the Overall Hospital Quality Star Rating to help patients compare hospitals based on a 5-star scale. The star rating was designed to assess overall quality of the institution; thus, its validity toward specifically assessing surgical quality is unknown. To examine whether CMS high-star hospitals (HSHs) have improved patient outcomes and resource use in advanced laparoscopic abdominal surgery compared with low-star hospitals (LSHs). Using the University HealthSystem Consortium database (which includes academic centers and their affiliate hospitals) from January 1, 2013, through December 31, 2015, this administrative database observational study compared outcomes of 72 662 advanced laparoscopic abdominal operations between HSHs (4-5 stars) and LSHs (1-2 stars). The star rating includes 57 measures across 7 areas of quality. Patients who underwent advanced laparoscopic abdominal surgery, including bariatric surgery (sleeve gastrectomy, Roux-en-Y gastric bypass), colorectal surgery (colectomy, proctectomy), or hiatal hernia surgery (paraesophageal hernia repair, Nissen fundoplication), were included. Risk adjustment included exclusion of patients with major and extreme severity of illness. Main outcome measures included serious morbidity, in-hospital mortality, intensive care unit admissions, and cost. A total of 72 662 advanced laparoscopic abdominal operations were performed in patients at 66 HSHs (n = 38 299; mean [SD] age, 51.26 [15.25] years; 12 096 [31.5%] male and 26 203 [68.4%] female; 28 971 [75.6%] white and 9328 [24.4%] nonwhite) and 78 LSHs (n = 34 363; mean [SD] age, 49.77 [14.77] years; 9902 [28.8%] male and 24 461 [71.2%] female; 21 876 [67.6%] white and 12 487 [32.4%] nonwhite). The HSHs were observed to have fewer intensive care unit admissions (1007 [2.6%] vs 1711 [5.0%], P < .001) and lower mean cost ($7866 vs $8708, P < .001). No significant difference was

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

To explore the value of nutrition management in obese patients with type 2 diabetes mellitus(T2DM) after laparoscopic sleeve gastrectomy(LSG). Clinical data of 22 obese T2DM patients undergoing LSG from March 2013 to July 2015 in Fudan University Pudong Medical Center were collected. All the patients strictly followed the specialized instruction by nutritionists: diabetic and low calorie diet 3347.2 to 5020.8 kJ (800 to 1200 kcal) per day before the operation; low calorie liquid diet 2510.4 kJ(600 kcal) per day before operation for promoting gastric emptying; fasting diet before postoperative ventilation; clear liquid diet 1673.6 to 2510.4 kJ (400 to 600 kcal) per day after postoperative ventilation (liquid intake >2000 ml); low fat liquid diet 2928.8 to 3765.6 kJ (700 to 900 kcal) per day (protein 60 g per day at least, 2000 ml liquid) 2 weeks after the operation; semi-liquid diet 1 month after operation and gradually normal diet. All the 22 patients were followed up at 1 week, 1, 3, 6 months after operation on time. Changes of body weight, waist circumference, hip circumference, body mass index(BMI), blood glucose indexes induding fasting blood glucose(FBG), 2-hour postparandial blood glucose(PBG), fasting C-peptide, 2-hour postprandial C-peptide, fasting serum inculin(FINS), 2-hour postprandial inculin(INS), HbAlc, blood pressure and blood lipid indexes were observed and analyzed before and 1 week, 1, 3, 6 months after operation. The average age of 22 patients (10 men and 12 women) was 38.6 years (18 to 66 years). The duration of diabetes varied from 1 month to 15 years. Comorbidity included 12 patients of high blood pressure, 14 of fatty liver, 1 of coronary heart disease, 1 of gout, 1 of chronic thyroiditis and 1 of menstrual disorder. LSG was performed successfully in all the patients and no severe complications and transference to laparotomy occurred. As compared to pre-operation, at 6 months after operation, the average body weight decreased from (103.9±20

The arterial ligation during elective laparoscopic sigmoidectomy for diverticular disease can affect genito-urinary function injuring the superior hypogastric plexus, and can weaken the distal colonic stump arterial perfusion. Ligation of the inferior mesenteric artery distal to the left colic artery or the complete preservation of the inferior mesenteric artery can therefore be compared in terms of preservation of the descending sympathetic fibres running along the aorta to the rectum resulting in a different post operative genito urinary function. From January 2015 to March 2016, 66 patients underwent elective laparoscopic sigmoidectomy for diverticular disease among two enrolling hospitals. In one centre 35 patients underwent laparoscopic sigmoidectomy with the ligation of the inferior mesenteric artery distal to the left colic artery (low ligation). In the other centre 31 patient were operated on the same procedure with complete inferior mesenteric artery preservation (IMA preservation). There was no difference in terms of major complication occurred, first passage of stool and length of hospital stay between the two groups. Time of surgery was significantly shorter in LL group compared to IMA preserving group and intra operative blood loss was significantly lower in the LL group. There were no differences in the genito urinary function between the two group pre operatively, at 1 and 9 months post operatively. Genito urinary function did not significantly change across surgery in each groups. The low ligation and the IMA preserving vascular approach are safe end feasible techniques in elective laparoscopic sigmoidectomy for diverticular disease. They both prevent from genito-urinary post-operative disfunction and allow good post operative quality of life. The low ligation approach is related to shorter operative time and slower intra operative blood loss. Celsius.

Intraoperative identification of early gastric cancer is difficult to conduct during laparoscopic procedures. In this study, we investigated the feasibility and accuracy of a newly developed marking system using endoclips with radio frequency identification (RFID) tags in a canine model. RFID is a wireless near field communication technology. Among the open frequency bands available for medical use, 13.56 MHz is suitable for a surgical marking system because of the similar and linear signal decay both in air and in biological tissues. The proposed system consists of four parts: (a) endoclips with RFID tags, (b) endo-clip applier equipment, (c) laparoscopic locating probe, and (d) signal processing units with audio interface. In the experimental setting using canine models, RFID-tagged endoclips were applied to the mucosa of each dog's stomach. During the subsequent operation, the clips with RFID tags placed in five dogs were located by the detection of the RFID signal from the tag (RFID group), and the conventional clips in the other six dogs were located by finger palpation (FP group). The detected sites were marked by ablation on the serosal surface. Distance between the clips and the metal pin needles indicating ablated sites were measured with X-ray radiographs of the resected specimen. All clips were successfully detected by the marking system in the RFID group (10/10) and by finger palpation in the FP group (17/17). The medians of detection times were 31.5 and 25.0 s, respectively; the distances were 5.63 and 7.62 mm, respectively. The differences were not statistically significant. No adverse event related to the procedures was observed. Endoclips with RFID tags were located by our novel marking system in an experimental laparoscopic setting using canine stomachs with substantial accuracy comparable to conventional endoclips located by finger palpation through an open approach.

The First Laparoscopic Cholecystectomy

Prof Dr Med Erich Mühe of Böblingen, Germany, performed the first laparoscopic cholecystectomy on September 12, 1985. The German Surgical Society rejected Mühe in 1986 after he reported that he had performed the first laparoscopic cholecystectomy, yet in 1992 he received their highest award, the German Surgical Society Anniversary Award. In 1990 in Atlanta, at the Society of American Gastrointestinal Surgeons (SAGES) Convention, Perissat, Berci, Cuschieri, Dubois, and Mouret were recognized by SAGES for performing early laparoscopic cholecystectomies, but Mühe was not. However, in 1999 he was recognized by SAGES for having performed the first laparoscopic cholecystectomy–sAGES invited Mühe to present the Storz Lecture. In Mühe's presentation, titled “The First Laparoscopic Cholecystectomy,” which he gave in March 1999 in San Antonio, Texas, he described the first procedure. Finally, Mühe had received the worldwide acclaim that he deserved for his pioneering work. One purpose of this article is to trace the development of the basic instruments used in laparoscopic cholecystectomy. The other purpose is to give Mühe the recognition he deserves for being the developer of the laparoscopic cholecystectomy procedure. PMID:11304004
