Staple Line Reinforcement during Sleeve Gastrectomy with SeamGuard: Single-Center Retrospective Case-Control Study over a 5-Year Period. J Clin Med 2024; 13:3410. [PMID: 38929935 PMCID: PMC11203928 DOI: 10.3390/jcm13123410] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/16/2024] [Revised: 05/31/2024] [Accepted: 06/09/2024] [Indexed: 06/28/2024] Open
Abstract
Introduction: Various techniques and reinforcements have been proposed over the years in order to prevent leaks and bleeding after sleeve gastrectomy (LSG). The aim of this study was to retrospectively compare the staple line complication (SLC) rate in patients who underwent LSG with the use of bioabsorbable membrane (GORE® SEAMGUARD®, GoR) for staple line versus those who received no reinforcement. Methods: Data on all consecutive patients undergoing LSG between 1 January 2014 and 31 December 2018 were retrospectively reviewed. Patients were divided into two groups: the GoR+ group if the SeamGuard (GoR) was used and the GoR- group if no reinforcement was applied on the staple line. Preoperative demographics and rate of SLC were compared between groups. All cases of SLC coming from other centers were also reviewed. Results: A total number of 626 LSGs were performed at our institution during the study period. GoR was applied in 450 (71.9%) cases (GoR+ group), while NR was used in 176 (28.1%) patients (GoR- group). Two (1.13%) cases of leaking and two (1.13%) cases of bleeding occurred in the GoR- group, while no SLC was recorded in patients who received GoR (p < 0.05). Thirteen cases of SLC coming from other institutions were treated at our hospital; all these cases were performed without any SLR. Conclusion: In our case series, the use of GoR reduced the rate of SLC after LSG. In all cases of SLC coming from other institutions, no reinforcement had been applied on the staple line during LSG.

Abstract
Introduction: The staple line (SL) leak remains one of the most serious complications after laparoscopic sleeve gastrectomy (LSG). The present study aims to determine whether reinforcing the SL with sutures is effective in maintaining tissue integrity. Materials and Methods: LSG Specimens of 60 patients were ex vivo studied. The specimens were divided into three groups: In group 1, the entire SL was reinforced, while the upper half part of the SL was reinforced from fundus to antrum in group 2. The SL was not reinforced in group 3. Then, the pressure inside the sample was increased, and the bursting pressure location and pressure value during the bursting were recorded. Results: The bursting pressure was significantly higher in entire and half oversewed SL groups than the none reinforced group (group 1: 115 mmHg [95-170]; group 2: 95 mmHg [80-120]; group 3: 40 mmHg [22-60], respectively, [P < .001]). The most common site of bursting was in the middle ⅓ of SL (35, 53.8%), followed by the proximal ⅓ part of SL (18, 27.7%), and the distal ⅓ part of SL (12, 18.5%), respectively. The bursting site was significantly more frequent in the corpus than the other parts of the SL (P = .013). Conclusion: Reinforcing the SL with sutures preserves tissue integrity. Although bursting was most frequently observed in the corpus region ex vivo, the fact that almost all real-life leaks develop in the area close to the Angle of His. This situation suggests that strengthening the suture line with reinforcement alone will not be protective enough against leaks in the fundus line, and factors such as tissue ischemia may be considered.

Abstract
INTRODUCTION Indocyanine green fluorescence angiography (ICG-FA) is commonly used in general surgery, but its use in bariatric surgery is still marginal. Moreover, post-operative leaks remain a dramatic complication after this surgery and the leak tests available have poor performance preventing them. The aim of the present paper is to assess the use and utility of a new innovative technology based on quantitative measures of fluorescence signal intensity. MATERIAL AND METHODS From January 2022 to June 2022, 40 consecutive patients with a median age of 51 years and a preoperative median body mass index of 45.2 kg/m2 underwent bariatric surgery with quantitative ICG fluorescence angiography in our center. Two different types of surgery, based on the multidisciplinary evaluation, were performed: laparoscopic sleeve gastrectomy (LSG) and one anastomosis gastric bypass (OAGB). For ICG visualization, quantitative laparoscopic ICG platform was used to identify the vascular supply. RESULTS Thirteen patients underwent LSG and 27 patients underwent OAGB. ICG was performed in all patients with no adverse events. An adequate and satisfactory blood supply was assessed in each case. No case of post-operative leak was detected. CONCLUSIONS The quantitative ICG-FA seems to be a useful and promising tool for the prevention of complications in bariatric surgery but further studies are mandatory.

The Impact of Blood Pressure Switching (from Controlled Hypotension to Late Elevated Blood Pressure) During Laparoscopic Sleeve Gastrectomy: Controlled Clinical Trial. Obes Surg 2023; 33:2602-2607. [PMID: 37351766 DOI: 10.1007/s11695-023-06699-9] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/25/2023] [Revised: 06/10/2023] [Accepted: 06/16/2023] [Indexed: 06/24/2023]
Abstract
PURPOSE Laparoscopic sleeve gastrectomy (LSG) is the most done bariatric procedure. Bleeding and leak are the most common associated complications. Elevation of systolic blood pressure (SBP) leads to discovering the bleeding sites but results in a bloody field and increases the operative time. Controlled hypotension shortens the operative time, reduces tissue edema, and improves field vision. We aimed to test controlled hypotension during LSG. MATERIAL AND METHODS This was a randomized controlled trial that included 200 patients who were operated by LSG, randomly assigned to 2 equal groups: group 1, operated with controlled hypotensive anesthesia, and group 2, operated with elevated SBP to 140 mmHg. RESULTS Of the patients, 162 (81%) were females, and 38 (19%) were male. The mean BMI was 45.7 kg/m2. The mean age was 41.7 years. The operative time was 36.43 ± 6.73 min in group 1 vs. 44.71 ± 5.47 min in group 2. The mean of total number of used gauzes and clips was 2.70 ± 3.49 in group 1 vs. 8.83 ± 3.15 in group 2. The mean amount of drain output was 37.65 ± 21.90 ml in group 1 vs. 74.00 ± 16.54 ml in group 2. The mean drop in the postoperative hematocrit was 0.08 in group 1 vs. 0.22 in group 2. The incidence of postoperative bleeding was 0% in group 1 vs. 1% in group 2. CONCLUSIONS Controlled hypotensive anesthesia in LSG reduces the operative time, reduces the intraoperative bleeding, and improves the operative field.

Abstract
Bleeding and leaks are the most ominous postoperative complications after laparoscopic sleeve gastrectomy (LSG). Various staple line reinforcement (SLR) techniques have been innovated such as oversewing/suturing (OS/S), omentopexy/gastropexy, buttressing, and gluing. Currently, no high-quality evidence supports the use of one method over the others or even supports the use of SLR over no SLR. This study aimed to compare postoperative outcomes between LSG with OS/S versus LSG without any SLR.

Abstract
Staplers are widely used in clinics; however, complications such as bleeding and leakage remain a challenge for surgeons. To tackle this issue, buttress materials are recommended to reinforce the staple line. This Review provides a systematic summary of the characteristics and applications of the buttress materials. First, the physical and chemical properties of synthetic polymer materials and extracellular matrix used for the buttress materials are introduced, as well as their pros and cons in clinical applications. Second, we review the clinical effects of reinforcement mesh in pneumonectomy, sleeve gastrectomy, pancreatectomy, and colorectal resection. Based on the analysis of numerous research data, we believe that buttress materials play a crucial role in increasing staple line strength and reducing the probability of complications, such as bleeding and leakage. However, considering the requirements of bioactivity, degradability, and biosafety, non-crosslinked small intestinal submucosa (SIS) matrix material is the preferred candidate. It has high research and application value, but further studies are required to confirm this. The aim of this Review is to provide comprehensive guidance on the selection of materials for staple line reinforcement.

Abstract
Purpose Staple line reinforcement (SLR) during laparoscopic sleeve gastrectomy (LSG) is controversial. The purpose of this study was to perform a comprehensive evaluation of the most commonly utilized techniques for SLR. Materials and Methods Network meta-analysis of randomized controlled trials (RCTs) to compare no reinforcement (NR), suture oversewing (SR), glue reinforcement (GR), bioabsorbable staple line reinforcement (Gore® Seamguard®) (GoR), and clips reinforcement (CR). Risk Ratio (RR), weighted mean difference (WMD), and 95% credible intervals (CrI) were used as pooled effect size measures. Results Overall, 3994 patients (17 RCTs) were included. Of those, 1641 (41.1%) underwent NR, 1507 (37.7%) SR, 689 (17.2%) GR, 107 (2.7%) GoR, and 50 (1.3%) CR. SR was associated with a significantly reduced risk of bleeding (RR=0.51; 95% CrI 0.31–0.88), staple line leak (RR=0.56; 95% CrI 0.32–0.99), and overall complications (RR=0.50; 95% CrI 0.30–0.88) compared to NR while no differences were found vs. GR, GoR, and CR. Operative time was significantly longer for SR (WMD=16.2; 95% CrI 10.8–21.7), GR (WMD=15.0; 95% CrI 7.7–22.4), and GoR (WMD=15.5; 95% CrI 5.6–25.4) compared to NR. Among treatments, there were no significant differences for surgical site infection (SSI), sleeve stenosis, reoperation, hospital length of stay, and 30-day mortality. Conclusions SR seems associated with a reduced risk of bleeding, leak, and overall complications compared to NR while no differences were found vs. GR, GoR, and CR. Data regarding GoR and CR are limited while further trials reporting outcomes for these techniques are warranted. Graphical abstract ![]()

Abstract
Background:
Although considered a safe procedure, sleeve gastrectomy (SG) has a non-negligible risk of major postoperative complications related to it, with special attention to gastric leaks.
Aim:
Evaluate the clinical value of the methylene blue test (MBT) in predicting the occurrence of post-SG leaks.
Methods: Retrospective study that included 1136 patients who underwent SG with intraoperative MBT between 2012 and 2016. Sensitivity, specificity, positive predictive value (PPV) and negative predicted value (NPV) were calculated to determine the clinical correlation between the MBT and the occurrence of postoperative leaks. Staple line oversewing was performed in all patients who presented positive MBT.
Results:
Laparoscopic SG was performed in 97.0% of cases; open in 2.3%, and robotic in 0.7%. MBT was positive in 19 cases (1.67%). One positive MBT occurred during an open SG and the other 18 at laparoscopy. Moreover, there were nine cases (0.8%) of postoperative leaks, among which, only two presented positive MBT. MBT diagnostic value was evaluated through the calculation of sensitivity (22.0%), specificity (98.0%), PPV (11.0%) and NPV (99.0%). There were no cases of allergic reaction or any other side effect with the use of the methylene blue solution.
Conclusion:
MBT showed high specificity and negative predictive value, thus presenting an important value to rule out the occurrence of postoperative leaks.

Abstract
BACKGROUND Gastric obstructions, leaks and staple line bleeding are reported after laparoscopic sleeve gastrectomy (LSG). There is no ideal method or technique to avoid these mishaps. We added modified omentopexy (OP) to LSG to determine if there is any effect on gastric leaks and some other complications. METHODS This single institution case control study included two groups of morbidly obese patients undergoing LSG. They were grouped as omentopexy (OP) or no omentopexy (NP). Patient characteristics such as age, sex, ASA (American Society of Anesthesiologists) risk, body mass index (BMI), nutritional status and comorbidities were comparable. Postoperative follow-up was scheduled at 1 week, 1 month, 3 months, 6 months and 12 months. All received standard postoperative clinical, nutritional evaluation and PPI therapy for at least 3 months. RESULTS Total 737 patients underwent LSG from January 2012 to December 2017. Out of these, 370 that had OP and 367 that had NP were analyzed. NP group was subdivided into Lemberted Staple line (LS) and bioabsorbable staple line reinforcement (BSLR) groups. Gastric leaks and perforations were clubbed together as gastric disruptions (GD). Patients with at least 15 months of postoperative follow-up were included. Those who failed to follow up were excluded. GD was reported in 7 out of 367 NP patients (1.9%), while no GD was seen in 370 OP patients (P = 0.01). Bleeding was seen in 1 OP versus 2 NP patients (P = 0.6). Venous thromboembolism was reported in 2 OP versus 1 NP patients (P = 1). Wound infection was seen in 1 OP versus 2 NP patients (P = 0.6). Readmissions were noted in 2 OP versus 6 NP patients (P = 0.1). Pneumonia was seen in 2 OP and 2 NP patients (P = 1). Postoperative dehydration was seen in zero OP versus 1 NP patients (P = 0.4). Gastric obstruction was not seen in any of the patients. Postoperative gastric reflux was present in 49/370(13.2%) OP versus 57/367(15.4%) NP patients (P = 0.4). Within NP group, LS (Lemberting of Staple line) patients (286/367) had 4 GD (1.39%) versus no GD in OP (P = 0.03). BSLR (Bioabsorbable Staple line re-enforcement) patients (81/367) had 3 GD (3.7%) versus no GD in OP (P = 0.005). None of the groups had any mortality. CONCLUSIONS GD (gastric disruptions) were statistically significant, but the following bleeding, venous thromboembolism and gastroesophageal reflux did not reach statistical significance, which indicates that OP, if performed correctly with LSG, has favorable effects on gastric leaks.

Abstract
BACKGROUND Staple line reinforcement (SLR) is widely used to reduce major complications such as bleeding and leak after sleeve gastrectomy (SG). The present study aims to compare the running suture of SLR with a hybrid method by purse string suture of His angle, continuous inverted suture of proximal staple line and oversewing of distal staple line with omental coverage. METHODS This single center retrospective study included 914 patients underwent SG. Their surgical videos were reviewed. The patients were divided into two groups according to the SLR methods, including hybrid suture and running suture. The postoperative major complications, including bleeding, leak and obstruction, were evaluated. RESULTS Among 914 patients, 384 had hybrid suture while 530 had running suture of SLR. The overall incidence of staple line bleeding and disruption was 39.2% and 4.9% after stomach transection. Hybrid suture exhibited slightly shorter SLR suture time, and required less extra suture for the hemostasis of suture site bleeding after staple line reinforcement compared to running suture. The incidence of postoperative bleeding was significantly lower after hybrid suture than after running suture (0 vs 1.3%, P = 0.02). Two patients in running suture group were complicated with postoperative leak. There was no postoperative obstruction within all patients. 1-year excessive weight loss was similar between two groups. CONCLUSION Despite surgical complexity, hybrid suture seemed to be able to decrease the incidence of postoperative bleeding compared to running suture. However, its role on leak and obstruction requires further clinical validation.

Abstract
Backgrounds. One of the major complications after laparoscopic sleeve gastrectomy (LSG) is represented by leaks along the staple line. Several reinforcement techniques have been proposed, but scarce data about the real strengthening offered are present. Thus, we aimed to evaluate if different reinforcements produced different bursting pressures after LSG, and then to verify if the clinical application of the stronger reinforcement produced a reduction in leakage rate. Methods. We prospectively enrolled all consecutive obese patients that underwent LSG. We tested 3 different types of staple lines, as follows: group 1, no reinforcement; group 2, bioabsorbable buttress reinforcement; group 3, invaginating overrunning barbed suture. A burst pressure test was applied to the gastric specimen by means of high-resolution manometric catheter. After burst pressure tests, a subsequent consecutive series of patients were treated with the most effective reinforcement, and rate of leaks was recorded. Results. We enrolled in total 110 obese patients; 20 patients for each group of staple line reinforcement and then other 50 consecutive patients underwent LSG with the higher burst pressure staple line reinforcement. Median burst pressures were similar in group 1 and group 2; group 3 showed a statistically significant pressure increase (P < .0001) than group 1 and group 2, with a 5.2-fold value. Other consecutive 50 obese patients underwent LSG with overrunning reinforcement. In none of them a leak was detected. Conclusions. Reinforcement of the SG staple line, with overrunning suture, seems to drastically increase bursting pressures in an ex vivo model and it is promising when reproduced in vivo.

Abstract
BACKGROUND Nowadays, laparoscopic sleeve gastrectomy (LSG) is one of the most widely performed bariatric procedures. Different techniques have been described to reduce the rate of complications associated with the staple line, but no consensus has been reached. The aim of this study was to determine the incidence of surgical complications after LSG with three different approaches to the staple line. PATIENTS AND METHODS A retrospective matched analysis was performed, comparing three groups of 100 patients each: partial oversewing of the staple line (PO group), complete oversewing of the staple line (CO group), and reinforcement with buttress material (BM group). Operative time, early surgical complications (superficial surgical site infection, leakage and hemorrhage), length of stay, weight evolution, and revisional surgery rates were analyzed. RESULTS All three groups were comparable at baseline. All surgeries were performed laparoscopically. Operative time was significantly longer in the CO group (PO: 84.2 ± 22; CO: 104.7 ± 17; BM: 82.3 ± 22; PO vs CO, p = 0.021; BM vs CO, p = 0.011). There were no differences in length of stay, early surgical complications, and weight outcomes at 36 months between the groups. The need for a revisional surgery was significantly higher in the CO group compared to the PO group (PO: 3%; CO: 14%; BM: 9%; PO vs CO, p = 0.005). CONCLUSION The CO group required a longer operative time. There were no differences in early surgical complications between the groups. The CO group had a higher need for revisional surgery than the PO group.

Abstract
Background Staple-line leaks following laparoscopic sleeve gastrectomy (LSG) remain a concerning complication. Staple-line buttressing is largely adopted as an acceptable reinforcement but data regarding leaks have been equivocal. This study compared staple-line leaks in five reinforcement options during LSG: no reinforcement (NO-SLR), oversewing (suture), nonabsorbable bovine pericardial strips (BPS), tissue sealant or fibrin glue (Seal), or absorbable polymer membrane (APM). Methods This systematic review study of articles published between 2012 and 2016 regarding LSG leak rates aligned with the Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. Variables of interest included leak rates, bleeding, and complications in addition to surgical and population parameters. An independent Fisher’s exact test was used to compare the number of patients with and without leaks for the different reinforcement options. Results Of the 1633 articles identified, 148 met inclusion criteria and represented 40,653 patients. Differences in age (older in APM; p = 0.001), starting body mass index (lower in Suture; p = 0.008), and distance from pylorus (closer in BPS; p = 0.04) were observed between groups, but mean bougie size was equivalent. The overall leak rate of 1.5% (607 leaks) ranged from 0.7% for APM (significantly lower than all groups; p ≤ 0.007 for next lowest leak rate) to 2.7% (BPS). Conclusions This systematic review of staple-line leaks following LSG demonstrated a significantly lower rate using APM staple-line reinforcement as compared to oversewing, use of sealants, BPS reinforcement, or no reinforcement. Variation in surgical technique may also contribute to leak rates.

Abstract
Background Laparoscopic sleeve gastrectomy (LSG) with staple line reinforcement (SLR) is a popular and safe treatment option for morbid obesity. We have developed, devised, and described our own method of stapleless laparoscopic sleeve gastrectomy, which in our limited study appeared safe, efficacious, and potentially cost-effective. Methods We analyzed the outcome of our modified LSG in a case series of three middle-aged women (median age 42 years old). Our main modification was sutured closure of the stomach rather than the commonly utilized technique of stapled closure. Our primary measure of success was the occurrence of post-operative leak. Secondary measures were (a) length of operation, (b) duration of inpatient stay, and (c) percentage of weight loss at 6 and 12 months post operation. Results Median operative time = 132 min (120–195 min), and median inpatient stays were 2 days. No post-operative leaks were recorded. The median excess weight loss at 6 months was 39% of initial weight loss and 57.7% at 12 months. Conclusions Stapleless LSG has the potential to be an affordable alternative to the traditional LSG. High-powered studies and a formal cost analysis are required.

The impact of stapling technique and surgeon specialism on anastomotic failure after right-sided colorectal resection: an international multicentre, prospective audit. Colorectal Dis 2018; 20:1028-1040.

Abstract
AIM There is little evidence to support choice of technique and configuration for stapled anastomoses after right hemicolectomy and ileocaecal resection. This study aimed to determine the relationship between stapling technique and anastomotic failure. METHOD Any unit performing gastrointestinal surgery was invited to contribute data on consecutive adult patients undergoing right hemicolectomy or ileocolic resection to this prospective, observational, international, multicentre study. Patients undergoing stapled, side-to-side ileocolic anastomoses were identified and multilevel, multivariable logistic regression analyses were performed to explore factors associated with anastomotic leak. RESULTS One thousand three hundred and forty-seven patients were included from 200 centres in 32 countries. The overall anastomotic leak rate was 8.3%. Upon multivariate analysis there was no difference in leak rate with use of a cutting stapler for apical closure compared with a noncutting stapler (8.4% vs 8.0%, OR 0.91, 95% CI 0.54-1.53, P = 0.72). Oversewing of the apical staple line, whether in the cutting group (7.9% vs 9.7%, OR 0.87, 95% CI 0.52-1.46, P = 0.60) or noncutting group (8.9% vs 5.7%, OR 1.40, 95% CI 0.46-4.23, P = 0.55) also conferred no benefit in terms of reducing leak rates. Surgeons reporting to be general surgeons had a significantly higher leak rate than those reporting to be colorectal surgeons (12.1% vs 7.3%, OR 1.65, 95% CI 1.04-2.64, P = 0.04). CONCLUSION This study did not identify any difference in anastomotic leak rates according to the type of stapling device used to close the apical aspect. In addition, oversewing of the anastomotic staple lines appears to confer no benefit in terms of reducing leak rates. Although general surgeons operated on patients with more high-risk characteristics than colorectal surgeons, a higher leak rate for general surgeons which remained after risk adjustment needs further exploration.

Abstract
Morbid obesity surgery has increased by 450 per cent in the past decade. Preferred surgical techniques have also changed, and since 2014, the most common surgical procedure worldwide has been laparoscopic sleeve gastrectomy (LSG). The most serious complication of this surgery is staple-line leaks, which leads to significant increases in cost and a considerable rate of mortality. This study aimed to investigate the effects of staples used in LSG on the development of staple-line leaks. The sample of the study comprised 70 patients that consecutively underwent surgery at Dokuz Eylül University Hospital between March 2014 and June 2015. The patients were divided into two equal groups. For the first group, resection was performed using blue-green EndoGIA™ cartridges (BGC) (Medtronic, Norwalk, CT). In the other group, purple Tri-Staple™ cartridges (TSC) (Medtronic) were used. To examine the effect of the cartridge type, the point and pressure of leak was determined from fresh specimens following saline infusion. No statistically significant difference was found between the two groups in terms of mean age, body mass index, gender distribution or comorbidity. The median number of cartridges used was five in both groups. The resistance of the staple line to intragastric pressure was found to be significantly higher in the TSC group compared with the BGC group [51.94 (618.34) mmHg and 39.77 (617.09) mmHg, respectively, P = 0.005]. Most applications undertaken to reduce the risk of leak development in LSG aim to reinforce the staple line. There are very few studies that investigated the quality of staple line, and none examined the effect of staple cartridges on the development of leaks. Therefore, we conducted this study to fill this gap in the literature. The results revealed that tissue thickness cartridge compatibility had a role in the development of leaks during the resection of gastric tissue in which the thickness is reduced from the distal to the proximal portion. We conclude that during vertical sleeve gastrectomy, using TSC that are compatible with a wider range of tissue thickness results in more durable staple lines than EndoGIA™ cartridges.

Abstract
Objective To assess the outcome and safety of staple line over-sewing for patients undergoing laparoscopic sleeve gastrectomy (LSG). Study design and location Retrospective descriptive analysis conducted at Shifa International Hospital Islamabad. Materials and methods Consecutive patients undergoing LSG as a treatment for morbid obesity from October 2013 to December 2016 were included in the study after approval from the ethical review board. Patients were divided into two groups: group A who underwent reinforcement using Vicryl 2.0 and group B where no reinforcement was done. Results A total of 225 patients underwent LSG between October 2013 and December 2016, including 147 females (65.4%) and 78 males (34.6%). Both groups were comparable in terms of age, body mass index (BMI) and gender distribution (p-value more than 0.05). There was one leak in group A (1.36%), none in group B. The bleeding rate was 4.3% in group A and 2.7% in group B. Conclusion This was a retrospective analysis of all the patients who underwent LSG, and it was observed that there was no added benefit of sewing the staple line in terms of rate of bleeding and leak.

Abstract
BACKGROUND AND OBJECTIVES A new technology involving indocyanine green (ICG) fluorescence angiography has been introduced to assess tissue perfusion and perform vascular mapping during laparoscopic surgery. The purpose of this study was to describe the use of this technology to identify the variable blood supply patterns to the stomach and gastroesophageal (GE) junction during laparoscopic sleeve gastrectomy (LSG), which may help in preserving the blood supply and preventing ischemia-related leaks. METHODS Eighty-six patients underwent LSG and were examined intraoperatively with fluorescence angiography at an academic bariatric center from January 2016 to September 2017. Before the construction of the SG, 1 mL ICG was injected intravenously, and near infrared fluorescence imaging technology was used to identify the blood supply of the stomach. Afterward, the LSG was created with attention to preserving the identified blood supply to the GE junction and gastric tube. Finally, 3 mL ICG was injected to ensure that all the pertinent blood vessels were preserved. RESULTS Eighty-six patients successfully underwent the laparoscopic procedure with no complications. The following patterns of blood supply to the GE junction were found: (1) a right-side-dominant pattern (20%), arising from the left gastric artery; (2) a right-side-accessory pattern (36%), running in the gastrohepatic ligament and comprising either an accessory hepatic artery or an accessory gastric artery; and (3) a left-side accessory pattern arising from tributaries from the left inferior phrenic artery significantly contributing to the right-side blood supply. In addition, in 10% of the cases both right and left accessory patterns were present simultaneously. CONCLUSION ICG fluorescence angiography allows determination of the major blood supply to the proximal stomach before any dissection during sleeve gastrectomy, so that an effort can be made to avoid unnecessary injury to these vessels during the procedure.

Abstract
INTRODUCTION Laparoscopic sleeve gastrectomy (LSG) is one of the most frequently performed bariatric procedures performed worldwide. However, staple line-related complications have become a major challenge for bariatric surgeons. The aim of this study was to evaluate the morbidity in a cohort of patients who underwent LSG with imbricated oversewing of the staple line at a single high-volume center. MATERIALS AND METHODS We retrospectively reviewed prospectively collected data for all patients who underwent LSG to treat obesity at our institution from January 2010 to September 2016. All practitioners had undergone training with a single senior bariatric surgeon using oversewing as staple line reinforcement (SLR). RESULTS In total, 1023 LSGs were performed (female, 67.3%; mean age, 40.6 ± 10.8 years; median preoperative body mass index, 37 ± 4.5 kg/m2). The mean operative time was 67.6 ± 23.4 min (range, 30-150 min). The rate of conversion to open surgery was 0.3%. Early complications were noted in 18 patients (1.8%), including 5 cases of bleeding (0.5%). No leaks, stenosis, or mortality occurred. CONCLUSIONS LSG is a safe technique, but staple line-associated complications can be life-threatening. In this series, no leaks occurred from the very beginning of the surgeons' experience in LSG. Imbricated oversewing of the staple line, proper mentoring, and performance of surgery in appropriate settings are good approaches to decreasing complications.

Abstract
Purpose Duodenal stump fistula (DSF) is a serious complication after gastrectomy for gastric cancer. Although risk evaluation and management of DSF were presented by some investigators, there was no technical attempt has been made to prevent DSF during laparoscopic gastrectomy until now. Methods Consecutive 99 patients were enrolled from April 2014 to February 2016 in 2 institutes. All patients were performed laparoscopic gastrectomy for gastric cancer. After cutting of duodenal stump, laparoscopic reinforcement suture (LARS) commenced with continuous invagination method or interrupted method by barbed suture. Clinicopathologic features and postoperative outcomes were analyzed. Results Fifty-six patients had comorbidity including 5 patients with duodenal ulcer. Most patients were performed distal gastrectomy with B-II, and 10 patients total gastrectomy with Roux en Y esophagojejunostomy. Although there were 2 esophagojejunostomy leakage and 1 artificial lesser curvature leakage, DSF did not occurred at all in this study. Mean operation time was 3 hours and mean LARS procedure time was 8 minutes. Conclusion LARS of duodenal stump can be considered as one of prevention methods of DSF during laparoscopic gastrectomy for gastric cancer. So this new technique will be necessary to appropriately evaluate by prospective randomized controlled trial in the future.

Abstract
INTRODUCTION Laparoscopic sleeve gastrectomy (LSG) is one of the most popular bariatric procedures. The procedure is associated with serious staple-line complications such as bleeding, leaks, and stenosis. AIM To determine whether oversewing the staple line, compared with clipping, in LSG reduces the incidence of postoperative bleeding. MATERIAL AND METHODS We conducted a parallel-group, prospective, randomized controlled trial (RCT) of 100 patients who underwent LSG for obesity at a single institution between May 2014 and August 2015. Patients were assigned to one of two groups for reinforcement of the staple line: the oversewing group (staple line oversewn) or the clipping group (staple line clipped). The primary outcome was reoperation for hemodynamic instability caused by staple-line bleeding within 72 h postoperatively. The secondary outcomes were operative duration, length of hospital stay, postoperative leaks, and postoperative stenosis. RESULTS Mean operative duration was longer in the oversewing group (78.2 ±20.5 min) than in the clipping group (64.1 ±16.5 min, p < 0.001). Mean length of hospital stay was comparable in both groups. Postoperatively, there was no significant between-group difference in bleeding (oversewing, n = 0 vs. clipping, n = 2 (4.6%); p = 0.21) or in stenosis and leakage (both outcomes: oversewing, n = 0, vs. clipping, n = 1 (2.3%); p = 0.46). CONCLUSIONS Oversewing the staple line prolongs operative duration. No conclusions can be drawn regarding the effects of oversewing on staple-line bleeding, postoperative leakage and stenosis, or length of hospital stay.

Abstract
BACKGROUND Leak is the second most common cause of death after bariatric surgery. The leak rate after laparoscopic sleeve gastrectomy (LSG) ranges between 1.1 and 5.3 %. The aim of the paper is to provide an overview of the current pathogenic and promoting factors of leakage after LSG on the basis of recent literature review and to report the evidence based preventive measures. METHODS Risk factors and pathogenesis of leakage after LSG were examined based on an extensive review of literature and evidence based analysis of the most recent published studies using Oxford centre for evidence-based medicine, 2011, levels of evidence. RESULTS Pathogenesis of leakage after LSG can be attributed to mechanical or ischemic causes. Many factors can predispose to leakage after LSG which are either technically related or patient related. Awareness of these predisposing factors and technical tips may decrease the incidence of leakage. CONCLUSIONS This review reports factors promoting leak and gives technical recommendations to avoid leak after LSG based on the available evidence and expert consensus which encompasses: (1) use a bougie size ≥40 Fr, EL:1, (2) begin the gastric transection 5-6 cm from the pylorus, EL:2-3, (3) use appropriate cartridge colors from antrum to fundus, EL:1, (4) reinforce the staple line with buttress material, EL:1, (5) follow a proper staple line, (6) remove the crotch staples, EL:4, (7) maintain proper traction on the stomach before firing, (8) stay away from the angle of His at least 1 cm, EL:1, (9) check the bleeding from the staple line, (10) perform an intraoperative methylene blue test, EL:4.
