Abstract
Bariatric surgery has been shown to have a variety of metabolically beneficial effects for patients with type 2 diabetes (T2D), and is now also called metabolic surgery. At the 2nd Diabetes Surgery Summit held in 2015 in London, the indication for bariatric and metabolic surgery was included in the “algorithm for patients with type T2D”. With this background, the Japanese Society for Treatment of Obesity (JSTO), the Japan Diabetes Society (JDS) and the Japan Society for the Study of Obesity (JASSO) have formed a joint committee to develop a consensus statement regarding bariatric and metabolic surgery for the treatment of Japanese patients with T2D. Eventually, the consensus statement was announced at the joint meeting of the 38th Annual Meeting of JSTO and the 41st Annual Meeting of JASSO convened in Toyama on March 21, 2021. In preparing the consensus statement, we used Japanese data as much as possible as scientific evidence to consider the indication criteria, and set two types of recommendation grades, “recommendation” and “consideration”, for items for which recommendations are possible. We hope that this statement will be helpful in providing evidence-based high-quality care through bariatric and metabolic surgery for the treatment of obese Japanese patients with T2D.

Laryngopharyngeal Reflux Among Patients Undergoing Bariatric Surgery. Obes Surg 2021; 31:3749-3757. [PMID: 34046825 DOI: 10.1007/s11695-021-05492-w] [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: 07/21/2020] [Revised: 05/14/2021] [Accepted: 05/20/2021] [Indexed: 10/21/2022]
Abstract
PURPOSE The effect of altered subsphincteric gastric volume and pressure after bariatric surgery on laryngopharyngeal reflux (LPR) remains largely unknown. This was a cross-sectional pilot study conducted between January 2018 and January 2019 to identify changes in LPR symptoms and signs in bariatric surgery patients presurgery and postsurgery. MATERIALS AND METHODS Thirty-four patients listed for bariatric surgery in a single tertiary referral center were recruited, where 31 (77.4% female, mean age 46.3 ± 8.9 years) fulfilled the eligibility criteria. Of the eligible patients, 54.8% and 45.2% underwent sleeve gastrectomy (SG) and gastric bypass (GB), respectively. LPR symptoms were assessed using the self-reported reflux symptom index (RSI). Video-recorded endolaryngeal signs were scored using the reflux finding score (RFS) by two blinded otolaryngologists. Patients' presurgical and 3-month postsurgical body mass index (BMI), RSI, and RFS were determined. Patients were deemed as having LPR when RSI > 13 or RFS > 7. RESULTS There was a significant correlation between the postsurgical RSI and RFS changes (Pearson's r = 0.474, p = 0.007). Of the 31 patients, 12.9% (RSI) and 6.4% (RFS) recovered from preexisting LPR, whereas 22.6% (RSI) and 3.2% (RFS) developed new de novo LPR postsurgery. The postsurgical mean RFS change improved significantly in the GB group compared with that of the SG group (p < 0.05). CONCLUSION LPR is best assessed clinically using a multimodal approach (RSI and RFS). Bariatric surgery may worsen or lead to de novo LPR. Recognizing the LPR outcomes in these patients is paramount for optimal voice, speech, and swallowing functions.

Abstract
INTRODUCTION There is significant variation in practices concerning Roux-en-Y gastric bypass (RYGB) among bariatric surgeons, but there is currently a lack of robust data on the nature and extent of these variations. The purpose of this study was to understand global variations in practices concerning RYGB. METHODS A questionnaire-based survey on Survey Monkey® was created, and the link was shared freely on various social media platforms. The link was also distributed through a personnel email network of authors. RESULTS A total of 657 surgeons from 65 countries completed the survey. Crohn's disease and liver cirrhosis were considered absolute contraindications for RYGB by 427 surgeons (64.98%) and 347 surgeons (53.30%), respectively. More than 68.5% of surgeons performed routine upper GI endoscopy while 64.17% performed routine ultrasound of abdomen preoperatively. The majority of surgeons (77.70%) used the perigastric technique for Gastric pouch creation. Approximately, 79.5% used orogastric bougie. More than 70% of the respondents did not use any staple line reinforcement routinely. Only 17.67% of surgeons measured the whole small bowel length, and the majority of surgeons (86.5%) used constant length of BP limb. Approximately, 89% used constant length of alimentary limb. Approximately, 95% of surgeons preferred antecolic bypass, and more than 86% routinely closed the Petersen defect. Marginal ulcer prophylaxis was used by the majority (91.17%). Almost 95% of surgeons recommended lifelong vitamin and mineral supplements. CONCLUSION This survey identifies global variations in practices concerning RYGB. It identifies several areas for future research and consensus building.

Abstract
BACKGROUND The most commonly performed bariatric procedures are laparoscopic Roux-en-Y gastric bypass (RYGB) and sleeve gastrectomy (LSG). Impact of learning curves on operative outcome has been well shown, but the necessary learning curves have not been clearly defined. This study provides a systematic review of the literature and proposes a standardization of phases of learning curves for RYGB and LSG. METHODS A systematic literature search was performed using PubMed, Web of Science, and CENTRAL databases. All studies specifying a number or range of approaches to characterize the learning curve for RYGB and LSG were selected. RESULTS A total of 28 publications related to learning curves for 27,770 performed bariatric surgeries were included. Parameters used to determine the learning curve were operative time, complications, conversions, length of stay, and blood loss. Learning curve range was 30-500 (RYGB) and 30-200 operations (LSG) according to different definitions and respective phases of learning curves. Learning phases described the number of procedures necessary to achieve predefined skill levels, such as competency, proficiency, and mastery. CONCLUSIONS Definitions of learning curves for bariatric surgery are heterogeneous. Introduction of the three skill phases competency, proficiency, and mastery is proposed to provide a standardized definition using multiple outcome variables to enable better comparison in the future. These levels are reached after 30-70, 70-150, and up to 500 RYGB, and after 30-50, 60-100, and 100-200 LSG. Training curricula, previous laparoscopic experience, and high procedure volume are hallmarks for successful outcomes during the learning curve.

Abstract
Background The aim of this study was to assess the learning curve of one anastomosis gastric bypass (OAGB-MGB) at the start of a low volume bariatric unit and analyze its impact as a preceding procedure to Roux-en Y gastric bypass (RYGB). Methods From January 2014 to December 2017, all patients who underwent bariatric surgeries in our teaching hospital that were performed by the same surgeon were enrolled. The first 47 patients who underwent OAGB-MGB were assigned to group A. RYGB has been offered as a treatment option since July 2016; thereafter, 26 patients who underwent OAGB-MGB and 32 patients who underwent RYGB at the same time interval were assigned to group B and group C, respectively. Baseline characteristics, perioperative outcomes and percentage of total weight loss (%TWL) up to 12 months postoperatively were collected and analyzed between groups. Results Compared to the patients in group C, those in groups A and B were older (39.4 yrs. and 42.2 yrs., respectively, vs. 34.2 yrs.; p = 0.021) and predominantly male (48.9 and 73.1%, respectively vs. 40.6%; p = 0.04), and they had a higher body mass index (41.8 kg/m2 and 43.3 kg/m2, respectively vs. 37.7 kg/m2; p = 0.002) and a higher incidence of hypertension (44.7 and 61.5%, respectively vs. 21.9%; p = 0.008). In addition, the operation time was significantly reduced (118.2 min and 115.8 min, respectively vs. 153.1 min; p < 0.001), and the length of stay was shortened (3.0 days and 2.9 days, respectively vs. 3.4 days; p = 0.002) in groups B and C compared to group A. No mortality, conversion or leakage was reported throughout the study period. The 30-day complication rate was decreased in group C compared to groups A and B (0% vs. 6.4 and 7.7%, respectively; p = 0.307). The %TWL at the 12-month follow-up was 36.3, 30.9 and 28.3% for groups A, B and C, respectively (p < 0.001). Conclusion Our study verified the early emergence of a learning curve effect for OAGB-MGB, and the proficiency acquired can be transferred to subsequent practice for RYGB in terms of acceptable operation time and length of stay without an increase in complications.

Abstract
Background: Laparoscopic Roux-en-Y gastric bypass (RYGB) is one of the most common procedures to treat morbid obesity. Abdominal drains are often placed during the operation to detect complications earlier. The aim of this study was to assess the benefit of routine drain placement during laparoscopic RYGB. Materials and Methods: A consecutive series of patients undergoing laparoscopic RYGB between 2017 and 2018 was analyzed. The sample was randomized before the procedure into two groups: with abdominal drain (G1) and without abdominal drain placement (G2). Patients with intraoperative complications were excluded from the randomization. Postoperative complications and pain (visual analogue scale) were compared between groups. Results: A total of 84 patients were included; 45 belonged to G1 and 39 to G2. Mean age (G1 44 years versus G2 48 years) and body mass index (G1 43 kg/m2 versus G2 44 kg/m2) were similar in both groups. There were no significant differences between groups in preoperative comorbidities. Mean operative time was 92 minutes in both groups. Mean pain score at postoperative day 0 was similar in both groups (G1 3.2 versus G2 3.5, P = .58), but was higher in G1 at postoperative day 1 (G1 3.1, G2 1.1, P = .02). Postoperative Clavien-Dindo I-II complications were similar in both groups (G1 9% versus G2 1%, P = .37). No major complications, reoperations, or 30-day mortality occurred in the entire cohort. Conclusions: Drain placement in laparoscopic RYGB was associated with greater postoperative pain and did not show benefits in early detection of postoperative complications. Routine placement of abdominal drain in laparoscopic RYGB might not be recommended.

Abstract
Fistula development is a serious complication after bariatric surgery. We performed a systematic review and meta-analysis to assess the efficacy of fistula closure and complications associated with endoscopic stent treatment of fistulas, developed after bariatric surgeries, particularly Roux-en-Y gastric bypass (RYGB) and gastric sleeve (GS). Studies involving patients with fistula after RYGB or GS and those who received stent treatment only were selected. The analyzed outcomes were overall success rate of fistula closure, mean number of stents per patient, mean stent dwelling time, and procedure-associated complications. Current evidence from identified studies demonstrates that, in selected patients, endoscopic stent treatment of fistulas after GS or RYGB can be safe and effective.

Abstract
BACKGROUND Gastrointestinal leak remains one of the most dreaded complications in bariatric surgery. We aimed to evaluate risk factors and the impact of common perioperative interventions on the development of leak in patients who underwent laparoscopic bariatric surgery. STUDY DESIGN Using the 2015 database of accredited centers, data were analyzed for patients who underwent laparoscopic sleeve gastrectomy or Roux-en-Y gastric bypass (LRYGB). Emergent, revisional, and converted cases were excluded. Multivariate logistic regression was used to analyze risk factors for leak, including provocative testing of anastomosis, surgical drain placement, and use of postoperative swallow study. RESULTS Data from 133,478 patients who underwent laparoscopic sleeve gastrectomy (n = 92,495 [69.3%]) and LRYGB (n = 40,983 [30.7%]) were analyzed. Overall leak rate was 0.7% (938 of 133,478). Factors associated with increased risk for leak were oxygen dependency (adjusted odds ratio [AOR] 1.97), hypoalbuminemia (AOR 1.66), sleep apnea (AOR 1.52), hypertension (AOR 1.36), and diabetes (AOR 1.18). Compared with LRYGB, laparoscopic sleeve gastrectomy was associated with a lower risk of leak (AOR 0.52; 95% CI 0.44 to 0.61; p < 0.01). Intraoperative provocative test was performed in 81.9% of cases and the leak rate was higher in patients with vs without a provocative test (0.8% vs 0.4%, respectively; p < 0.01). A surgical drain was placed in 24.5% of cases and the leak rate was higher in patients with vs without a surgical drain placed (1.6% vs 0.4%, respectively; p < 0.01). A swallow study was performed in 41% of cases and the leak rate was similar between patients with vs without swallow study (0.7% vs 0.7%; p = 0.50). CONCLUSIONS The overall rate of gastrointestinal leak in bariatric surgery is low. Certain preoperative factors, procedural type (LRYGB), and interventions (intraoperative provocative test and surgical drain placement) were associated with a higher risk for leaks.

BACKGROUND This study aims to evaluate the 12-24-month impact of bariatric surgery on the foremost modifiable traditional risk factors of cardiovascular disease. METHODS A systematic review and meta-analysis of prospective interventional studies reporting the most commonly performed laparoscopic surgical procedures, i.e., Roux-en-Y gastric bypass (RYGB), adjustable gastric banding (AGB), and cardiovascular risk reduction after surgery. RESULTS The bibliographic research conducted independently by two authors yielded 18 records. When looking at RYGB and AGB separately, we observed a relevant heterogeneity (I (2) index ≥87 %) when BMI reduction was considered as the main outcome. When hypertension, type II diabetes, and hyperlipidemia risk reduction was estimated, a highly significant beneficial effect was found. The risk reduction was 0.33 [0.26; 0.42] for type II diabetes, 0.52 [0.42; 0.64] for hypertension, and 0.39[0.27; 0.56] for hyperlipidemia (P < 0.0001 for all outcomes considered). When looking at surgical technique separately, a higher but not statistically significant risk reduction for all outcomes considered was found. Results from the meta-regression approach showed an inverse relation between cardiovascular risks and BMI reduction. CONCLUSIONS The present study showed an overall reduction of cardiovascular risk after bariatric surgery. According to our analysis a BMI reduction of 5 after surgery corresponds to a type II diabetes reduction of 33 % (as reported by Peluso and Vanek (Nutr Clin Pract 22(1):22-28, 2007); SAS Institute Inc., (2000-2004)), a hypertension reduction of 27 % (as reported by Buchwald and Oien (Obes Surg 23(4):427-436, 2013); Valera-Mora et al. (Am J Clin Nutr 81(6):1292-1297, 2005)), and a hyperlipidemia reduction of 20 %(as reported by Adams et al. (JAMA 308(11):1122-31, 2012)); Alexandrides et al. (Obes Surg 17(2):176-184, 2007). In summary, our study showed that laparoscopic bariatric surgery is an effective therapeutic option to reduce the cardiovascular risk in severe obese patients.

Abstract
Purpose: Obesity is a growing epidemic leading to worldwide public health concerns. Bariatric surgery is an option for patients with a body mass index (BMI) >40 kg/m2 or BMI of >35 kg/m2 with serious comorbid conditions. This meta-analysis examines the effect of bariatric surgery on the improvement or resolution of hypertension. Methods: Two independent investigators conducted a literature search of PubMed (1990-2013) and Cochrane databases using the terms bariatric surgery and hypertension to identify appropriate human adult studies published in English. Studies were included if they reported the number of patients with hypertension prior to undergoing any bariatric surgery procedure and whether the hypertension improved or resolved postsurgery. The number of patients with hypertension and their response rates were extracted and analyzed using RevMan 5.2.5. Results: In all, 31 prospective and 26 retrospective studies met all criteria. The types of bariatric surgery performed included Roux-en-Y, gastric banding, laparoscopic adjustable gastric banding, vertical gastric banding, sleeve gastrectomy, duodenal switch, and biliopancreatic diversion. The time to first follow-up after surgery varied from 1 week to 7 years. Of the 57 studies, 32 reported improvement of hypertension in 32 628 of 51 241 patients (odds ratio [OR] = 13.24; 95% CI = 7.73, 22.68; P < 0.00001); 46 studies reported the resolution of hypertension in 24 902 of 49 844 patients (OR = 1.70; 95% CI = 1.13, 2.58; P = 0.01). A random-effects model was used because the heterogeneity between the studies was high ( I2 = 97%). Conclusion: The results of this meta-analysis indicate that patients who undergo bariatric surgery experience improvement and resolution of their hypertension.

Abstract
There is a strong relationship between obesity and the development of obstructive sleep apnea (OSA). Respectively, bariatric surgery is often touted as the most effective option for treating obesity and its comorbidities, including OSA. Nevertheless, there remains paucity of data in the literature of the comparison of all the specific types of bariatric surgery themselves. In an effort to answer this question, a systematic review was performed, to determine, of the available bariatric procedures [Roux-en-Y gastric bypass, laparoscopic sleeve gastrectomy, or biliopancreatic diversion (BPD)], which procedures were the most efficacious in the treatment of OSA. A total of 69 studies with 13,900 patients were included. All the procedures achieved profound effects on OSA, as over 75 % of patients saw at least an improvement in their sleep apnea. BPD was the most successful procedure in improving or resolving OSA, with laparoscopic adjustable gastric banding being the least. In conclusion, bariatric surgery is a definitive treatment for obstructive sleep apnea, regardless of the specific type.

Abstract
BACKGROUND Laparoscopic Roux-en-Y gastric bypass (LRYGB) is a potentially complicated surgery with significant hospitalisation, especially during the learning curve. There are inadequate data on fast-track LRYGB in relation to learning curve. This study highlights the outcomes of a fast-track LRYGB service. METHODS This observational study examined the perioperative outcome data of 406 consecutive LRYGB patients over a 4-year period. Perioperative outcome data were analysed and compared between severe obesity, morbid obesity and super obesity groups. RESULTS Mean BMI was 48.6 ± 8.3, mean age was 42 years and male to female ratio was 1:4. About 4% of patients had concurrent ventral hernia repair. Median duration of combined LRYGB and ventral hernia repair was 115 min, compared to 95 min for LRYGB alone (p = 0.09). Intraoperative complication rate was 0.5%. Postoperative complications occurred in 3.4% of patients with 60% within 24 h. The complication rate per obesity group was <7% and similar between groups (p = 0.4). There was no perioperative mortality. More super obese patients received postoperative intensive care compared to others (p = 0.001). Mean length of hospital stay was similar between obesity groups and decreased from 2 to 1 day over 2 years. There was a learning curve of 109 cases over 2 years. CONCLUSION LRYGB is a safe technique of bariatric surgery with low risk of perioperative complications. Establishing a fast-track LRYGB service requires a learning curve of 100 cases, and a good indicator is length of hospital stay, which decreases as the service matures. Most LRYGB patients can be safely discharged by 24 h.

Abstract
BACKGROUND AND AIMS Unsatisfactory patient compliance and unfavorable results of weight loss let centers prefer the Roux-en-Y gastric bypass (RYGB) as a combined restrictive and malabsorptive procedure. The aim of this study was to evaluate results of laparoscopic adjustable gastric banding (LAGB) versus laparoscopic RYGB. SETTING The study was conducted at Centre Hospitalier Emil Mayrisch Clinic for specialized care (n = 618 beds) in Luxembourg (South). MATERIALS AND METHODS Of 620 procedures, 204 patients had LAGB and 416 LRYGB. Short-term (t(1), 6 months to 2 years), middle-term (t(2), 2 to 5 years), and long-term follow-up (t(3), >5 years) were performed, including weight loss evolution, Bariatric Analysis, and Reporting Outcome System (BAROS). RESULTS Percent EBWL mean values for LAGB vs. LRYGB were at t(1) 64.3 vs. 79.5, p = 0.01; at t(2) 49.4 vs. 91, p < 0.0001; and at t(3) 52.6 vs. 79.9, p < 0.0001. The BAROS mean values were at t(1) 3.81 vs. 4.00, p = 0.183; at t(2) 3.57 vs. 4.12, p < 0.001; and at t(3) 3.71 vs. 4.04, p = 0.02. Major complication rate (<30 days) was similar (p = 0.601). Long-term (>30 days) complications were more common after LAGB (14.3 versus 3.6%, p < 0.001). Fifty patients (25%) required a second and 36 patients (18%) a third operation (LRYGB). CONCLUSION The significant difference in %EBWL and BAROS and late adverse events with high re-operation rates in LAGB made the LRYGB more attractive.

Abstract
Obesity is associated with increased risk for cardiovascular (CV) disease (CVD) and CV mortality. Bariatric surgery has been shown to resolve or improve CVD risk factors, to varying degrees. The objective of this systematic review was to determine the impact of bariatric surgery on CV risk factors and mortality. A systematic review of the published research was performed to evaluate evidence regarding CV outcomes in morbidly obese bariatric patients. Two major databases (PubMed and the Cochrane Library) were searched. The review included all original reports reporting outcomes after bariatric surgery, published in English, from January 1950 to July 2010. In total, 637 studies were identified from the initial screen. After applying inclusion and exclusion criteria, 52 studies involving 16,867 patients were included (mean age 42 years, 78% women). The baseline prevalence of hypertension, diabetes, and dyslipidemia was 49%, 28%, and 46%, respectively. Mean follow-up was 34 months (range 3 to 155), and the average excess weight loss was 52% (range 16% to 87%). Most studies reported significant decreases postoperatively in the prevalence of CV risk factors, including hypertension, diabetes, and dyslipidemia. Mean systolic pressure reduced from to 139 to 124 mm Hg and diastolic pressure from 87 to 77 mm Hg. C-reactive protein decreased, endothelial function improved, and a 40% relative risk reduction for 10-year coronary heart disease risk was observed, as determined by the Framingham risk score. In conclusion, this review highlights the benefits of bariatric surgery in reducing or eliminating risk factors for CVD. It provides further evidence to support surgical treatment of obesity to achieve CVD risk reduction.

Abstract
BACKGROUND Bleeding after gastric bypass can be a life-threatening event and challenging to manage. With an increase in the number of bariatric procedures performed in recent years, it is important to be cognizant of the frequency, presentation, and management of this complication. The purpose of the present study was to evaluate the incidence and management of bleeding complications after gastric bypass surgery. METHODS A review of prospectively maintained bariatric surgery databases was conducted at 2 tertiary bariatric units. All patients who presented with gastrointestinal and intra-abdominal bleeding after gastric bypass during a 10-year period were identified, and their charts were reviewed. RESULTS A total of 4466 patients who underwent gastric bypass during the 10-year period had reliable morbidity data available and were included in the present study. Of the 4466 patients, 42 (.94%) experienced a bleeding complication postoperatively. Of these patients, 20 (47.6%) had undergone previous abdominal surgery. Bleeding occurred in the early postoperative period (<30 d) in 30 (71%); the etiology of which included bleeding from the staple lines, iatrogenic visceral injury, or mesenteric vessel bleeding. Early postoperative bleeding required operative intervention to achieve hemostasis in 43%. Late postoperative bleeding (n = 12) were usually secondary to marginal ulceration and warranted surgical intervention in 33.3%. Previously undiagnosed bleeding diatheses were identified in 14.3%. CONCLUSION Gastrointestinal bleeding after gastric bypass, although infrequent, is a difficult clinical scenario. Nonoperative management is feasible for hemodynamically stable patients. Surgical intervention is merited for patients with hemodynamic compromise, those who do not respond to transfusion, and those in whom the bleeding source cannot be adequately identified nonoperatively.

Abstract
Obesity is now a common problem among HIV-infected patients receiving antiretroviral therapy (ART). Gastric bypass surgery may be an option for some patients who have failed diet and therapeutic lifestyle changes, changes in ART or other treatment modalities for HIV/ART-related lipohypertrophy and obesity. However, few data are available regarding HIV-related outcomes after such surgery and its impact on ART tolerability. We present here a case series of seven subjects with HIV infection who underwent bariatric surgery. Viral suppression was maintained in five of the six subjects who were receiving ART prior to surgery, including three subjects who experienced surgical complications. The median (range) decrease in body mass index (BMI) postoperatively was 10 kg/m(2) (6-28 kg/m(2)). Improvements were also seen in serum lipid fractions with median (range) changes in total cholesterol of -19 mg/dL (-61 to +3 mg/dL) and triglycerides of -185 mg/dL (-739 to +35 mg/dL). Four of the subjects had a reduction in their metabolic medication prescriptions postoperatively. Three of the subjects experienced postsurgical complications. Based on our experience, bariatric surgery may provide an effective treatment modality for obesity and its related comorbidities in the HIV-infected population while not sacrificing virologic suppression. Larger studies are needed to verify these results, especially in regards to surgical complications.

Abstract
The prevalence of obesity and type 2 diabetes has increased over recent decades. Bariatric surgery has been widely used in clinical practice. There are three categories of bariatric surgery: restrictive surgery, malabsorptive surgery, and combined restrictive and malabsorptive surgery. Bariatric surgery causes not only weight loss but also a remarkable and durable remission of type 2 diabetes mellitus. However, the mechanism of diabetes resolution remains unclear. In addition to weight loss and food intake restriction, incretins also seem to contribute to the resolution of type 2 diabetes following bariatric surgery. In this article, we will review the efficacy and safety of various bariatric procedures and the mechanism of diabetes resolution resulting from bariatric surgery.

Abstract
The purpose of this study was to compare the outcomes of patients with different types of gastroesophageal reflux disease (upright, supine, or bipositional) after laparoscopic Nissen fundoplication and determine if patients with upright reflux have worse outcomes. Two hundred and twenty-five patients with reflux confirmed by 24-h pH monitoring were divided into three groups based on the type of reflux present. Patients were questioned pre- and post-fundoplication regarding the presence and duration of symptoms (heartburn, regurgitation, dysphagia, cough and chest pain). Symptoms were scored using a 5-point scale, ranging from 0 (no symptom) to 4 (disabling symptom). Esophageal manometry and pH results were also compared. There was no statistically significant difference in lower esophageal sphincter length, pressure or function between the three groups. There was no significant difference in any of the postoperative symptom categories between the three groups. The type of reflux identified preoperatively does not have an adverse effect on postoperative outcomes after Nissen fundoplication and should not discourage physicians from offering antireflux surgery to patients with upright reflux.

Abstract
OBJECTIVE Stricture formation at the gastrojejunal anastomosis is a relatively common complication after laparoscopic Roux-en-Y gastric bypass (LRYGB). The objective of this study was to report the incidence of stomal strictures after LRYGB in our institution and report our experience with their management by endoscopic balloon dilatation. METHODS This is a retrospective study of 1012 patients who underwent LRYGB from January 2001 to May 2004. Patients with nausea and vomiting after the surgery, suspected of having gastrojejunal (GJ) anastomotic stricture, had upper endoscopy. Stomas less than 10 mm in diameter, or those not allowing passage of the scope were considered significant strictures and were treated with balloon dilations. Dilations were performed with a through-the-scope (TTS) balloon, with sizes ranging from 6 to 18 mm. The following data were collected from these patients: age, sex, body mass index (BMI), comorbidities, size of balloon catheter, time from surgery until symptoms onset, number of endoscopies needed to relief symptoms, and complications of the procedure. RESULTS Sixty-one patients (46 females and 15 males) were found to have anastomotic strictures, corresponding to an incidence of 6%. In total, 134 upper endoscopies were performed, with 128 dilatations. The average age was 41.7 years (range: 19-68 years); mean preoperative BMI was 45 kg/m(2) (range: 42-61 kg/m(2)). Mean time from surgery to symptoms onset was 2 months (range: 1-6 months). The number of dilations per patient was as follows: a single dilation in 28% of patients, two dilations in 33%, three dilations in 26%, four dilations in 11.5%, and five dilations in 1.5% of patients. All the patients responded to dilation without need for formal surgical revision. However, after balloon dilatation three patients (4.9%), all females, had bowel perforation by radiological criteria (free air on X-ray), which corresponded to 2.2% of all dilatations. The maximum balloon size used in this group was 13.5 mm. All three patients had exploratory laparoscopy without finding of perforation site. They were treated with bowel rest, intravenous antibiotics for 7 days, and drain placement. No factors were identified to predict a risk of perforation. CONCLUSION This is the largest study to evaluate the outcome of endoscopic dilatations of GJ strictures after RYGB. Endoscopic balloon dilation is a safe and effective treatment for anastomotic strictures. However, it carries a small risk of perforation. Further case studies are needed to determine risk factors for perforation and if the patients can be managed conservatively in this setting.

Abstract
BACKGROUND Early upper GI hemorrhage (UGH) is a potential complication after laparoscopic Roux-en-Y gastric bypass (RYGBP), and early reoperative intervention is the most accepted treatment. Experience with endoscopic treatment is limited. OBJECTIVE Our purpose was to describe the role of endoscopy and injection therapy in the management of early UGH after laparoscopic RYGBP. DESIGN Case series study. SETTING Endoscopy Unit, Hospital Clínic, University of Barcelona, Barcelona, Spain. PATIENTS We describe the endoscopic treatment of 6 patients with early UGH within 24 hours after a RYGBP. INSTRUMENTATION Upper endoscopy was performed in all 6 cases. The origin of the bleeding was identified at the staple line in all cases, and epinephrine alone or combined with polidocanol was successfully injected in 5 of 6 patients. RESULTS Endoscopic therapy arrested active bleeding without any complications in all cases without the need for further surgery or endoscopic treatments. LIMITATION Our experience is limited to 6 cases. CONCLUSION Early postoperative UGH after RYGBP may be adequately controlled with endoscopic treatment and may obviate the need for surgery. Further data are necessary to evaluate the safety and the efficacy of this approach.

Abstract
BACKGROUND AND AIMS Upper gastrointestinal hemorrhage (UGIH) is an infrequent complication (1-3.8%) following laparoscopic Roux-en-Y gastric bypass (LRYGB). The safety and efficacy of endoscopic management of immediate postoperative bleeding is unknown. We sought to determine how frequently UGIH complicates LRYGB and whether endoscopic management is successful in controlling hemorrhage. METHODS Retrospective chart review of all patients who developed UGIH following LRYGB from November 2001 to July 2005 at a large suburban teaching hospital. RESULTS Of 933 patients who underwent LRYGB, 30 (3.2%) developed postoperative UGIH. An endoscopic esophagogastroduodenoscopy (EGD) was performed in 27/30 patients (90%). All were found to have bleeding emanating from the gastrojejunostomy (GJ) staple line. Endoscopic intervention was performed in 24/30 (80%) with epinephrine injection and heater probe cautery being used most commonly. Endoscopic therapy was ultimately successful in controlling all hemorrhage, with 5 patients (17%) requiring a second EGD for rebleeding. No patient required surgery to control hemorrhage. One patient aspirated during the endoscopic procedure with subsequent anoxic encephalopathy and died 5 days postoperatively. Twenty-one patients (70%) developed UGIH in the intraoperative or immediate postoperative period (<4 h postoperative). The mean length of stay was significantly longer in these patients (2.84 vs 4.1, P= 0.001). CONCLUSIONS (a) UGIH complicates LRYGB in a small but significant number of patients. (b) Bleeding usually occurs at the GJ site. (c) EGD is safe and effective in controlling hemorrhage with standard endoscopic techniques. (d) UGIH occurs most commonly in the immediate postoperative period and may be best managed in the operating room with the patient intubated to prevent aspiration.

Abstract
BACKGROUND Previous studies have reported a high prevalence of Helicobacter pylori infection in patients undergoing Roux-en-Y gastric bypass (RYGB) and a greater incidence of anastomotic ulcer in patients positive for H. pylori, leading to recommendations for routine preoperative screening. Our hypotheses were that the prevalence of H. pylori in patients undergoing RYGB is similar to that of the general population and that preoperative H. pylori testing and treatment does not decrease the incidence of anastomotic ulcer or pouch gastritis. METHODS A retrospective analysis of H. pylori serology, preoperative and postoperative endoscopy findings, and the development of anastomotic ulcer or erosive pouch gastritis was performed. All patients positive for H. pylori received treatment. Univariate parametric and nonparametric statistical tests, as well as multiple logistic regression analyses, were performed. RESULTS A total of 422 LRYGB patients were included in the study. Of these patients, 259 (61.4%) were tested for H. pylori and 163 (38.6%) were not. Of the 259 patients, 58 (22.4%) tested positive for H. pylori, 197 (76.1%) tested negative, and 4 (1.5%) had an equivocal result. Postoperatively, 53 patients (12.6%) underwent upper endoscopy. Of these 53 patients, 19 (4.5%) had positive endoscopy findings for anastomotic ulcer (n = 16) or erosive pouch gastritis (n = 3). Five patients underwent biopsy at endoscopy; all biopsies were negative for H. pylori. No difference was found in the rate of positive endoscopy between patients tested preoperatively for H. pylori (5%) and patients not tested (3.7%). CONCLUSION The results of our study have shown that the prevalence of H. pylori infection in patients undergoing RYGB is similar to that of the general population. Our study has shown that H. pylori testing does not lower the risk of anastomotic ulcer or pouch gastritis.

Abstract
BACKGROUND Morbid obesity is a growing epidemic among adolescents. Bariatric surgery has proven to be the only long-term effective method in treating morbidly obese adults for over a decade. The laparoscopic approach has become a popular option. This study tested the hypothesis that laparoscopic Roux-en-Y gastric bypass is a feasible option in teenaged patients with good results through an adult bariatric program. METHODS All patients under the age of 20 at the time of surgery were included in this study. Each patient had undergone a laparoscopic Roux-en-Y gastric bypass. Charts were reviewed for preoperative evaluation, operative time, complications, and length of hospital stay. Percentage of excess body weight lost (%EBWL) was calculated at the follow-up. RESULTS Of the 202 patients who underwent a laparoscopic gastric bypass procedure at our institution, 5 (2%) were teenagers. The mean age was 18 years (range, 17-19). The mean height was 69 inches (range, 61-75). Average weight was 323 lbs (range, 227-394). The mean preoperative body mass index was 48 kg/m2 (range, 44-56). All patients had medical and psychological clearance prior to surgery. Mean operative time was 150 minutes (range, 130-172). There were no complications in this subset of patients. All 5 patients were discharged on postoperative day 2. Follow-up ranged from 17.8 to 44.8 months. The mean %EBWL was 77% (range, 58%-88%). CONCLUSIONS The laparoscopic gastric bypass procedure is technically feasible in teenaged patients, with excellent results even when performed in an adult bariatric program. Long-term data will be needed to determine its role in the treatment of morbidly obese adolescents.

Abstract
BACKGROUND Laparoscopic Roux-en-Y gastric bypass (LRYGBP) can be technically challenging. It is imperative that patient morbidity and mortality are minimized while teams are on the learning curve for this procedure. METHODS This retrospective study evaluated the peri-operative risk of LRYGBP utilizing a two-consultant surgeon approach in a newly established bariatric service. 100 consecutive patients undergoing LRYGBP were included. Two consultants participated in each procedure. RESULTS Median operative duration was 113 minutes (range 80-240) and fell with increasing experience [127 minutes (range 90-240) in cases 1-50 and 105 minutes (range 80-210) in cases 51-100; P=0.009]. Multivariate analysis found operation time correlated only with number of procedures performed (P<0.001). There were no conversions to laparotomy. Intra-operatively, 2 patients had hand-assisted completion of the jejuno-jejunostomy, and 2 underwent laparoscopic revision of the reconstruction. Postoperative complications were observed in 8 patients on the operative admission. Median stay was 4 days (range 3-7). 4 patients required readmission. There was no mortality. Percentage of excess BMI loss was 47%, 53% and 70% at 3, 6 and 12 months respectively. CONCLUSION A learning curve for LRYGBP is evidenced in this series by reduction in operative time with increasing experience. Complication rates in line with large published series can be achieved by adopting a two-surgeon approach, which we propose as a safe method to adopt in the development of new bariatric services.

Abstract
Known complications of Roux-en-Y gastric bypass causing abdominal pain and obstructive symptoms include biliary colic, anastomotic ulcer, anastomotic stenosis, or internal hernia. This case report describes a new complication in a patient 15 months post-bypass: a bezoar at the gastrojejunal anastomosis, the nidus of which was a length of permanent suture material which had eroded through the gastric wall. We include endoscopic images of the bezoar, a review of the related gastric bypass literature, and describe the changes made in our practice as a result of this complication.

Abstract
BACKGROUND Obesity is associated with multiple comorbidities, including hypertension, hypercholesterolemia, hypertriglyceridemia, diabetes mellitus, obstructive sleep apnea, osteoarthritis, back/extremity pain, gastroesophageal reflux disease (GERD), asthma, and depression. Surgical weight loss can markedly improve if not resolve many of these comorbidities. METHODS This was a retrospective study of 400 consecutive gastric bypass patients, analyzing postoperative resolution or improvement of obesity-related comorbidities. RESULTS Mean follow-up period for these patients was 12.8 months, with a range of 0.3-30.6 months. Comorbidities were present in 21%-65% of the patients. Hypertension, hyperlipidemia, diabetes mellitus, obstructive sleep apnea, GERD, and asthma either resolved or improved in 80%-100% of the patients. Arthritis, back or extremity pain, and depression also improved but to a lesser extent, in 52%-73% of patients. Our patients' quality of life greatly improved even at 6 weeks postoperatively in 35% of the patients, and this increased to >80% after 18 months. CONCLUSIONS Gastric bypass surgery for the treatment of morbidly obese patients has a profound positive impact on obesity-related comorbidities. Also, patients' quality of life is dramatically improved in the majority of patients when compared with their preoperative status.

Abstract
BACKGROUND The reported learning curve for laparoscopic Roux-en-Y gastric bypass (LRYGB) is 20-100 cases. Our aim was to investigate whether advanced laparoscopic skills could decrease the learning curve for LRYGB with regard to major morbidity. METHODS The senior author performed all operations in this series. His training included a laparoscopic fellowship without bariatric surgery, six years in surgical practice focusing on upper abdominal laparoscopic surgery, two courses on bariatric surgery at national meetings, one week of observing a bariatric program, and two mentored LRGBY cases. A comprehensive obesity program was put in place before the program began. Data were collected prospectively and reviewed at the series' end. Results are presented as mean +/- standard deviation and standard statistical analysis was applied. RESULTS Between December 2003 and February 2005, 107 LRYGB operations were performed. Mean operative time decreased significantly with experience (p < 0.0001) and was 154 +/- 29, 132 +/- 40, 127 +/- 29, and 114 +/- 30 min by quartile. Mean length of stay was 2.9 +/- 1.6 days. Mean excess weight loss was 45.3% (n = 41) at six months. There were no conversions to an open procedure, no anastomotic leaks, no pulmonary embolisms, and no bowel obstructions. The five major complications (3 in the first 50 and 2 in the last 57 cases, p = NS) were two cases of biliopancreatic limb obstruction, two cases of significant gastrointestinal bleeding from anastomotic ulcer, and one case of gastric volvulus of the remnant stomach. CONCLUSIONS A bariatric fellowship and/or extended mentoring are not required to safely initiate a bariatric program for surgeons with advanced laparoscopic skills. Operative time decreases significantly with experience, but morbidity and mortality remain low even early in the learning curve. A comprehensive obesity program seems necessary for success.

Abstract
BACKGROUND The claim that the "mini"-gastric bypass (MGB) procedure with its loop gastrojejunostomy is safer and equally effective to the Roux-en-Y gastric bypass (RYGB) procedure has been promoted before validation. Rumors of unreported complications and the accuracy of follow-up are additional concerns. This study was undertaken to identify MGB patients who require or required revisional surgery at 5 hospitals within the region of the United States where the MGB procedure originated to assess the claim that revision to RYGB is rarely needed. METHODS The databases of 5 medical centers were retrospectively searched to identify patients undergoing surgical revision after a MGB procedure, all of which had been done elsewhere. RESULTS A total of 32 patients were identified who presented with complications after undergoing an MGB procedure and required or require revisional surgery. The complications included gastrojejunostomy leak in 3, bile reflux in 20, intractable marginal ulcer in 5, malabsorption/malnutrition in 8, and weight gain in 2. Of the 32 patients, 21 required conversion to RYGB and an additional 5 have planned revisions in the future. Also, 2 patients were treated with Braun enteroenterostomies and 4 required 1 or more abdominal explorations. CONCLUSIONS The results of this preliminary review have confirmed that MGB does require revision in some patients and that conversion to RYGB is a common form of revision. A national registry to record the complications and number of revisions is proposed to gain insight into the need for revision after MGB and other nontraditional bariatric procedures.

Abstract
BACKGROUND Most laparoscopic bariatric programs are situated in a community- or university-based hospital. The authors have recently initiated a program at a safety net hospital. This investigation hypothesizes that a laparoscopic bariatric program can be established at a safety net hospital with good clinical and financial results. METHODS A laparoscopic bariatric program was initiated December 2002 at a safety net hospital. The program included a dedicated operative suite, an operative team, a bariatric unit, and a clinical pathway. The data for all the patients who underwent laparoscopic gastric bypasses up to June 2003 were analyzed. The patients were analyzed by type of insurance: government-sponsored insurance (G) or commercial insurance (C). RESULTS There were 104 patients during this period. Their mean age was 40 years (range, 18-63 years), and their mean body mass index was 48 (range, 38-62). The median length of hospital stay was 2 days (mean, 3.9 days). Hypertension and diabetes were resolved for more than 80% of the patients. The average percentage of excess body weight loss was 73% after 1 year. There were no significant clinical differences between payor groups. The payor mix was 31% G and 69% C. The mean collection rates for hospital charges were 10% for G versus 53% for C (p < 0.0001). CONCLUSIONS A laparoscopic bariatric program can be established in a safety net hospital with good clinical results. Findings showed that 1-year weight loss and comorbidity improvement/resolution compares favorably with those of other programs. Despite the overall poor payor mix of many safety net hospitals, a bariatric program can be established and can attract a high rate of commercially insured patients.

Abstract
BACKGROUND The benefits of laparoscopic gastric bypass (LGB) include decreased pain, quicker recovery, and shorter hospital stay. Our hypothesis was that a clinical pathway for 48-hour discharge after LGB can be implemented safely. METHODS Charts of patients undergoing LGB were retrospectively reviewed to assess our prospectively placed clinical pathway. Patients were discharged within 48 hours if they met the criteria of the pathway. RESULTS There were 104 patients who underwent LGB with no intraoperative conversions. Complications included 5 leaks, 5 reoperations, and no mortality. In our series, 76% (n=79) of patients were discharged within 48 hours. Gender and body mass index (BMI) did not differ between those who were discharged in 48 hours and those who were not (P=not significant). No patient who was discharged in 48 hours required return before their scheduled appointment. CONCLUSIONS A majority of patients after LGB can be discharged safely in 48 hours. A formal clinical pathway helps decrease hospital stay without adverse patient outcome.

Abstract
BACKGROUND A decreased length of stay (LOS) is one of the many advantages of laparoscopic over open Roux-en-Y gastric bypass for the treatment of morbid obesity. However, the mean LOS after laparoscopic gastric bypass (LGB) ranges from 1.8 to 4.5 days. In addition, the LOS has tended to improve as bariatric programs have matured. With the use of a standardized perioperative care plan, we studied the effects of LOS on readmission rates in patients undergoing LGB in a new minimally invasive bariatric surgery program. METHODS All patients undergoing LGB between September 20, 2001 and April 5, 2004 were entered into a standardized perioperative care plan. All patient outcomes were entered into a prospective database. The discharge criteria included adequate oral intake and adequate pain control on oral medication. The reasons for patients staying >2 days were analyzed and documented. RESULTS A total 250 patients underwent LGB. Of these, 212 patients (84.8%) were discharged on postoperative day 2. The most common reason for a LOS >2 days was bleeding (42.1%), followed by nausea (26.3%), inadequate pain control on oral medication (15.8%), and various other reasons (15.8%). The mean LOS did not change with time (P = .19). Readmission within 30 days was significantly less in patients discharged by day 2 (1.9% versus 13.1%, P = .005). CONCLUSIONS The LOS remained constant as our program matured. The vast majority of patients undergoing LGB who have an uncomplicated postoperative course were safely discharged home on postoperative day 2. Patients staying >2 days were more likely to be readmitted within 30 days of discharge.

Abstract
Obesity has emerged as one of the most complex and debilitating diseases affecting the world's population. It is estimated that more than two thirds of Americans are overweight and more than 20% are obese. This disease is associated with many morbid conditions, including hypertension, coronary artery disease, hypoventilation, sleep apnea syndrome, diabetes mellitus, and an increased incidence of certain malignancies. Medical interventions for achieving and maintaining significant weight loss have generally failed, leaving surgery as the only effective treatment for durable weight loss. A number of surgical options are available today and can be grouped into two categories based on the mechanism of how the weight loss is achieved. Restrictive procedures include vertical banded gastroplasty (VBG), adjustable gastric banding (AGB), and Roux-en-Y gastric bypass (RYGB), although the latter does have some altered absorption as well. Largely malabsorptive procedures include biliopancreatic diversion (BPD) and biliopancreatic diversion with duodenal switch (BPD-DS). Whereas VBG has largely fallen out of favor due to inadequate long-term weight loss, the other procedures have proven successful in achieving and maintaining adequate weight loss. In addition, each has proven successful in reversing or ameliorating many of the comorbidities associated with obesity. RYGB is the most common procedure performed in the United States and is considered the gold standard. It has the best short- and long-term results for safety, efficacy, and durability, and it has been proven to be superior in results to those for AGB. In experienced hands, this technically challenging procedure can now be performed laparoscopically. This method has the same weight loss and health benefits as the open procedure while achieving all the added benefits of a minimally invasive approach. Long-term data seem to support the malabsorptive procedures as most effective in the superobese. All the procedures require compliance and long-term nutritional follow-up.

Abstract
BACKGROUND In surgical treatment of morbid obesity, maintaining a restrictive anastomosis is key to long-range success. However, laparoscopic Roux-en-Y gastric bypass (LRYGB) may result in gastrojejunal (GJ) stricture, requiring treatment in up to 27% of patients. METHODS This is a retrospective review of the outcome of 223 consecutive LRYGB patients. Patients developing stricture received standard endoscopic balloon dilation by the same surgeon. Stricture and nonstricture groups were compared for excess body weight loss (EBWL) at 1, 3, 6, and 12 months. RESULTS GJ stricture requiring dilation occurred in 38 patients (17%). After dilation all patients were relieved of stricture symptoms and none required revision. By 12 months, patients with stricture had an EBWL of 86% compared with nonstrictured patients at 75%. CONCLUSION Endoscopic balloon dilation is a safe and effective treatment option for GJ stricture. Improved weight loss occurred for patients with stricture requiring dilation.

Abstract
Morbid obesity has reached epidemic proportions in the United States. Laparoscopic gastric bypass is rapidly becoming the procedure of choice for treatment of morbid obesity. Results demonstrate that the surgery is technically safe. Outcomes are similar to open gastric bypass,but with markedly lower incidences of wound-related and cardiopulmonary complications. Patients also have shorter hospital stay, decreased pain and faster recovery.

Abstract
BACKGROUND Laparoscopic Roux-en-Y gastric bypass (LRYGB) is a challenging operation for the treatment of morbid obesity with well-demonstrated effectiveness in weight lost. There are several variations to the technique. METHODS From September 2000 to July 2004, 600 consecutive patients underwent surgery for morbid obesity at our institution. The surgical technique employed was LRYGB with totally hand-sewn gastrojejunal anastomosis (GJA). All patients were considered candidates for laparoscopic approach regardless of age, gender, body mass index (BMI), or previous bariatric or digestive surgery. RESULTS Mean BMI was 44.4 +/- 7.6 kg/m2. Thirty-two patients had undergone previous failed bariatric procedures. Conversion to an open procedure was necessary in three patients. Seventy-two patients (12%) developed early complications, including 23 (3.8%) leaks at the GJA (eight in the first 18 patients). Mortality rate was 1.1% (one death was related to GJA leakage). Early and late reoperation rates were 5.3 and 1.8%, respectively. Rate plateau of morbidity and mortality was reached after the first 18 patients when the surgical technique was fully standardized. CONCLUSIONS LRYGB is a technically demanding procedure for the surgical treatment of morbid obesity with significant morbidity during the learning curve. The learning curve can be soon overcome, reaching a rate plateau of complications after adequate training. Morbidly obese patients should be operated on in expert bariatric surgical laparoscopic units to obtain the best results.

Abstract
BACKGROUND Anastomotic leak after laparoscopic gastric bypass (GBP) can result in significant morbidity, mortality, and consumption of healthcare resources. Fibrin sealant has been used clinically in the prevention of leak; however, its efficacy has not been clearly demonstrated. The aims of this study were to (1) develop an iatrogenic leak model in swine, (2) examine the efficacy of fibrin sealant in sealing iatrogenic anastomotic leak, and (3) review our experience with the use of fibrin sealant in 66 patients who underwent laparoscopic GBP. METHODS This study was performed in three phases. In phase 1, laparoscopic gastrojejunostomy was performed in adult swine with iatrogenic disruption of the anastomotic staple line. The size of disruption was sequentially increased (6- to 12-F opening) until a leak model was developed. In phase 2, 16 animals underwent laparoscopic gastrojejunostomy with a 12-F disruption of the anastomosis; 10 animals (study group) had fibrin sealant (Tisseel VH) applied on the disrupted anastomosis and 6 animals (control group) did not receive fibrin sealant. Animals were sacrificed on postoperative day 5 or earlier if peritonitis developed and were examined for sealing of the anastomotic disruption and the presence of intraabdominal abscess. In phase 3, the outcome of 66 consecutive patients who underwent laparoscopic GBP with fibrin sealant applied at the gastrojejunostomy was reviewed. RESULTS In phase 1, an anastomotic leak model was developed with a 12-F disruption of the staple line. In phase 2, two control animals required early sacrifice for bile peritonitis; three control animals had intraabdominal abscess discovered at sacrifice and one animal did not have any evidence of intraabdominal abscess or leak. Of the 10 animals in the study group, all survived until sacrifice and none of these animals had evidence of intraabdominal abscess or persistent leak. Therefore, 83% of animals in the control group developed either leak or abscess compared to 0% in the study group (P < 0.01, Fisher's exact test). Clinically, no leak or intraabdominal abscess developed in 66 patients who underwent laparoscopic GBP with the use of fibrin sealant. CONCLUSIONS An anastomotic leak model was developed in swine with disruption of the stapled gastrojejunostomy to a 12-F opening. The use of fibrin sealant significantly reduces leak and abscess complication. Our results support the tissue sealing property of fibrin sealant and its use on high-risk gastrointestinal anastomosis.
