Abstract
OBJECTIVE This study aimed to evaluate the technical variations of one-anastomosis gastric bypass (OAGB) among IFSO-APC and MENAC experts. BACKGROUND The multitude of technical variations and patient selection challenges among metabolic and bariatric surgeons worldwide necessitates a heightened awareness of these issues. Understanding different perspectives and viewpoints can empower surgeons performing OAGB to adapt their techniques, leading to improved outcomes and reduced complications. METHODS The scientific team of IFSO-APC, consisting of skilled bariatric and metabolic surgeons specializing in OAGB, conducted a confidential online survey. The survey aimed to assess technical variations and considerations related to OAGB within the IFSO-APC and IFSO-MENAC chapters. A total of 85 OAGB experts participated in the survey, providing their responses through a 35-question online format. The survey took place from January 1, 2024, to February 15, 2024. RESULTS Most experts do not perform OAGB for children and adolescents younger than 18 years. Most experts create the gastric pouch over a 36-40-F bougie and prefer to create a gastrojejunostomy, at the posterior wall of the gastric pouch. An anti-reflux suture during OAGB is performed in all patients by 51.8% of experts. Most experts set a common limb length of > 4 m in revisional and conversional OAGBs to prevent nutritional complications. CONCLUSION The ongoing debate among metabolic and bariatric surgeons regarding the technical variations and patient selection in OAGB remains a significant point of discussion. This survey demonstrated the variations in technical aspects and patient selection for OAGB among MBS surgeons in the IFSO-APC and IFSO-MENAC chapters. Standardizing the OAGB technique is crucial to ensure optimal safety and efficacy in this procedure.

Abstract
PURPOSE This study presents the short- (less than 6 months) and medium-term (6 months to 2 years) outcomes for weight loss and type 2 diabetes mellitus (T2DM) for all patients undergoing one anastomosis gastric bypass (OAGB) across multiple institutions between 2015 and 2021. MATERIALS AND METHODS A retrospective analysis of prospectively collected databases was performed including 1022 participants who underwent OAGB at multiple institutions by multiple surgeons between 2015 and 2021. Primary outcome was percentage total weight loss (TWL) and secondary outcomes were achieving resolution of T2DM; OAGB specific short- and medium-term complications including bile reflux, marginal ulceration and internal herniation. RESULTS One thousand and twenty-two patients underwent OAGB (81% primary surgery). A percentage of 34.1% (n = 349) had a preoperative diagnosis of type 2 diabetes mellitus (T2DM). Mean TWL was 33.6 ± 9% with a T2DM remission rate of 74% at 1-year post-op. Rates of bile reflux and marginal ulceration was 1.1% (n = 11) and 1.1% (n = 11). There were no cases of internal herniation during the follow-up period. CONCLUSION OAGB results has echoed previously published work as being efficacious and safe in a short-medium term. The prevalence of complications, especially bile reflux is overall low in our population and no current evidence exists to support an increased risk of metaplasia or malignancy related to bile within the stomach.

Abstract
OBJECTIVE One-anastomosis gastric bypass (OAGB) is considered an effective technique in weight reduction and remission of comorbidities. However, in common with many bariatric and metabolic/bariatric procedures, gastrointestinal side effects are frequently reported, but clinical experience varies. The objective of this study was to analyze the bowel function of patients who undergo OAGB looking at 5-year postoperative outcomes. METHOD This study is cross-sectional, descriptive and analytical, developed with individuals undergoing OAGB (n = 208) in yhe period between 2015 and 2020. The time periods evaluated were 1 to 6 months (T1), 6 to 12 months (T2), and 1 to 5 years (T3). Data analysis was performed using SPSS v.28.0, considering a significance level p ≤ 0.05. RESULTS 114 participants (54.8%), 79.8% women, mean age 47.0 ± 12.6 years, and BMI 40.1 ± 5.6 kg/m2, 51.9% dyslipidemia, 43.6% arterial hypertension, and 19.1% diabetes mellitus. The T1 group had more severe symptoms/nausea than the T2 group. The T2 group had a significantly lower defecation frequency than the T1 and T3 groups. As for the occurrence of diarrhea, associations were not found in the considered groups. The T3 group had a greater severity of constipation associated with greater difficulty in consuming red meat, white meat, rice, vegetables, and salads. CONCLUSIONS Gastrointestinal symptoms are prevalent in the first postoperative months. However, diarrhea was not common. The patient selection policy and surgical technique were decisive in this result. Constipation was prevalent in patients between 1 and 5 postoperative years. It was also prevalent in those who had food intolerance, which from a nutritional point of view is an adverse factor for optimal bowel function.

Abstract
Severe malnutrition following one-anastomosis gastric bypass (OAGB) remains a concern. Fifty studies involving 49,991 patients were included in this review. In-hospital treatment for severe malnutrition was needed for 0.9% (n = 446) of patients. Biliopancreatic limb (BPL) length was 150 cm in five (1.1%) patients, > 150 cm in 151 (33.9%), and not reported in 290 (65%) patients. OAGB was revised to normal anatomy in 126 (28.2%), sleeve gastrectomy in 46 (10.3%), Roux-en-Y gastric bypass in 41 (9.2%), and shortening of BPL length in 17 (3.8%) patients. One hundred fifty-one (33.8%) patients responded to treatment; ten (2.2%) did not respond and was not reported in 285 (63.9%) patients. Eight (0.02%) deaths were reported. Standardisation of the OAGB technique along with robust prospective data collection is required to understand this serious problem.

Abstract
This systematic review and meta-analysis aimed to investigate the incidence of new-onset gastroesophageal reflux, reflux change, esophagitis, Barrett's esophagus, and revision due to reflux, gastritis, and marginal ulcer after one-anastomosis gastric bypass (OAGB). We performed subgroup analyses based on primary and revisional OAGB and time of follow-up. Meta-analysis of 87 studies with 27,775 patients showed a 6% rate of new-onset reflux after OAGB. Preoperative reflux status did not change significantly after OAGB. The rate of esophagitis and Barrett's esophagus was 15% and 1%, respectively. The new-onset reflux rate after OAGB was significantly higher than gastric bypass but not different with sleeve gastrectomy. The current study showed a relatively low rate of reflux and its complications after OAGB, but it was significantly higher than Roux-en-Y gastric bypass.

Abstract
Gastro-oesophageal reflux disease (GORD) after one anastomosis gastric bypass (OAGB) remains a concern. We reviewed the current literature on revisional surgery after OAGB for GORD. MEDLINE, EMBASE, and PubMed databases were searched. We identified 21 studies, appraising 13,658 OAGB patients. A total of 230 (1.6%) patients underwent revisional surgery for GORD. Revision to Roux-en-Y configuration was performed in 211 (91.7%) patients. Six (2.6%) patients had a Braun entero-enterostomy added to the OAGB. Thirteen (5.6%) patients underwent excluded stomach fundoplication (ESF). Reflux symptoms resolved in 112 (48.6%) patients, persisted in 13 (5.6%) patients, and were not reported in 105 (45.6%) patients. Revisional surgery after OAGB for GORD appears to be rare, and when required, conversion to Roux-en-Y configuration is the commonest choice.

Abstract
BACKGROUND It has been suggested that shortening the length of the biliopancreatic limb (BPL) to 150 cm in one anastomosis gastric bypass (OAGB) would reduce nutritional complication rates without impairing weight loss outcomes. The aim of this study is to compare patients who underwent OAGB with a 200-cm BPL (OAGB-200) to patients with OAGB with a 150-cm BPL (OAGB-150) in terms of weight loss and late morbidity. METHODS This is a monocentric retrospective matched cohort study including patients with a body mass index between 35 and 50 kg/m2 who underwent an OAGB-150 or an OAGB-200. Patients were matched 1:1 based on age, sex, and body mass index, prior to bariatric surgery. RESULTS In total, 784 patients who underwent OAGB were included (OAGB-150 n = 392 and OAGB-200 (n = 392). There was no significant difference in terms of early morbidity. Regarding late morbidity in patients with an OAGB-150, significantly lower rates for marginal ulcer (OR = 0.4, CI 95% [0.2; 0.8], p = 0.006), incisional hernia (OR = 0.5, CI 95% [0.3; 1], p = 0.041), and bowel obstruction (OR = 0.3, CI 95% [0.1; 0.9], p = 0.039) were reported. Likewise, regarding late nutritional deficiencies, post-OAGB-150, a significantly lower number of patients with hypoalbuminemia (OR = 0.3, CI 95% [0.2; 0.7], p = 0.006), low vitamin B9 (OR = 0.5, CI 95% [0.2; 1], p = 0.044), and low ferritin (OR = 0.5, CI 95% [0.3; 0.8], p = 0.005) were observed. There was no significant difference in the percentage of excess BMI loss at 1, 2, 3, 4, and 5 years. CONCLUSION Compared to OAGB-200 in patients with BMI ≤ 50 kg/m2, OAGB-150 results in fewer nutritional deficiency rates long term, without impairing weight loss.

Abstract
BACKGROUND Efficacy and safety of OAGB/MGB (one anastomosis/mini gastric bypass) have been well documented both as primary and as revisional procedures. However, even after OAGB/MGB, revisional surgery is unavoidable in patients with surgical complications or insufficient weight loss. METHODS A questionnaire asking for the total number and demographics of primary and revisional OAGB/MGBs performed between January 2006 and July 2020 was e-mailed to all S.I.C. OB centres of excellence (annual caseload > 100; 5-year follow-up > 50%). Each bariatric centre was asked to provide gender, age, preoperative body mass index (BMI) and obesity-related comorbidities, previous history of abdominal or bariatric surgery, indication for surgical revision of OAGB/MGB, type of revisional procedure, pre- and post-revisional BMI, peri- and post-operative complications, last follow-up (FU). RESULTS Twenty-three bariatric centres (54.8%) responded to our survey reporting a total number of 8676 primary OAGB/MGBS and a follow-up of 62.42 ± 52.22 months. A total of 181 (2.08%) patients underwent revisional surgery: 82 (0.94%) were suffering from intractable DGER (duodeno-gastric-esophageal reflux), 42 (0.48%) were reoperated for weight regain, 16 (0.18%) had excessive weight loss and malnutrition, 12 (0.13%) had a marginal ulcer perforation, 10 (0.11%) had a gastro-gastric fistula, 20 (0.23%) had other causes of revision. Roux-en-Y gastric bypass (RYGB) was the most performed revisional procedure (109; 54%), followed by bilio-pancreatic limb elongation (19; 9.4%) and normal anatomy restoration (19; 9.4%). CONCLUSIONS Our findings demonstrate that there is acceptable revisional rate after OAGB/MGB and conversion to RYGB represents the most frequent choice.

Abstract
One anastomosis gastric bypass is now an accepted bariatric procedure in many countries. A rare but serious complication of OAGB is perforation of marginal ulcer with 0.5-1% incidence that needs urgent diagnosis and intervention. In cases of complicated or refractory ulcers, conversion to RYGB could be a definitive therapy.

Abstract
Introduction One anastomosis gastric bypass (OAGB) is an effective and safe treatment for morbidly obese patients. Longer biliopancreatic (BP) limb length is suggested to result in better weight loss outcomes, but to date, no data are available for the OAGB to substantiate this. We hypothesized that applying a longer BP-limb length in the higher BMI classes would result in more weight reduction so that the attained BMI would be comparable to patients with a lower BMI, thereby compensating for differences in baseline BMI. Method A retrospective cohort study in patients who underwent a primary OAGB at a teaching hospital in the Netherlands between January 2015 and December 2016. BP-limb length was tailored based on preoperative BMI. Patients were divided into three different groups depending on the length of the BP-limb: 150, 180, and 200 cm. Weight loss outcomes after 1 and 3 years and resolution of comorbidities were compared between these groups. Results Of the 632 included patients, a BP-limb length of 150 cm was used in 172 (27.2%), 180 cm in 388 (61.4%), and 200 cm in 72 (11.4%) patients. Despite more BMI loss, %EWL was lower and attained BMI remained higher in the groups with longer BP-limb lengths. After adjustment for the confounder preoperative BMI, longer BP-limb lengths were not associated with higher BMI loss. There was no difference in remission rates of comorbidities. Conclusion Attained BMI remained higher in spite of tailoring BP-limb length according to baseline BMI with no differences in remission rates of comorbidities. Graphical Abstract ![]()

Abstract
This review evaluates the indications and outcomes of one-anastomosis/mini gastric bypass (OAGB/MGB) reversal to normal anatomy. A systematic literature search and meta-analysis was performed in PubMed, Web of Science, and Scopus for articles published by October 1, 2020, including the keywords "one anastomosis gastric bypass," "OAGB," "mini gastric bypass," "MGB," "reversal," "reverse," "malnutrition," and "reversal bariatric surgery". After examining 182 papers involving 11,578 patients, 14 studies were included. A reversal was performed in 119 patients on average 23.6 months after the primary OAGB/MGB surgery. The mean body mass index (BMI) was 22.92 ± 3.47 kg/m2 and the mean albumin level was 25.17 ± 4.21 g/L at reversal. The mean length of the common channel (CC) was 383.57 ± 159.35 cm, with a mean biliopancreatic limb (BPL) length of 214.21 ± 48.45 cm. Pooled estimation of the meta-analysis of prevalence studies reported a prevalence of 1% for reversal. The major signs and symptoms of protein-energy malnutrition were the leading causes of the reversal of OAGB/MGB. Bleeding, leakage, and death due to severe liver failure were the most reported complications after reversal, with an overall incidence of 10.9%. In conclusion, OAGB/MGB reversal has a prevalence of 1% and has a complication rate of 10.9%. Protein-energy malnutrition with hypoalbuminemia was the most common etiology. The mean lengths of BPL and CC were reported as 215 cm and 380 cm, respectively, in the cases. Therefore, special attention should be paid to malnutrition in all OAGB/MGB patients during follow-up to prevent severe malnutrition and subsequent increase in reversal procedures.

Abstract
BACKGROUND It has been suggested that shortening the biliopancreatic limb (BPL) length with one anastomosis gastric bypass (OAGB) to 150 cm would reduce the revision rates for malnutrition. But, it remains unclear if this would not compromise the efficacy of this procedure. METHODS We examined our prospectively maintained database to compare the outcomes of patients who had their OAGB performed with a 150-cm BPL with those performed with a 200-cm BPL. RESULTS Medium-term weight loss data at 18-24 months was available for 343/398 (86.1% follow-up) patients. Of these, 225 had undergone OAGB-200 and 118 had undergone OAGB-150. The mean preoperative weight and body mass index were 141.6 ± 32.8 kg and 49.76 ± 8.6 kg/m2, respectively, in the OAGB-200 group compared with 133.7 ± 24.5 kg and 47.83 ± 7.2 kg/m2, respectively, in the OAGB-150 group. There was no significant difference in albumin and haemoglobin levels in the two groups at 18-month follow-up. The mean excess weight loss was 75.0% ± 20.1 in the OAGB-200 group and 74.0% ± 22.0 in the OAGB-150 group (p = 0.6714). A total of 89.7% (n = 202) patients achieved an excess weight loss (EWL) of ≥ 50.0% in the OAGB-200 group compared with 85.5% (n = 103) in the OAGB-150 group (p value = 0.4754). The mean total weight loss was 36.1% ± 9.2 in the OAGB-200 group compared with 34.0% ± 9.8 in the OAGB-150 group (p value = 0.0598). CONCLUSIONS OAGB performed with a BPL of 150 cm delivers weight loss outcomes similar to that seen with a BPL of 200 cm.

Abstract
BACKGROUND One-anastomosis gastric bypass/mini-gastric bypass (OAGB/MGB) remains controversial because it may cause chronic biliary reflux (BR). The risk of developing esogastric cancer due to BR after OAGB/MGB is based on the results of experimental rat studies using esojejunostomy (EJ). The aim of this study was to analyze the potential long-term consequences of BR on the esogastric mucosae in OAGB/MGB-operated rats and to compare these results to those from the use of EJ. METHODS Wistar rats received OAGB/MGB (n = 16), EJ (n = 16), and sham (n = 8) operations. Mortality and weight changes were evaluated throughout the experiment. BR was measured using magnetic resonance imaging (MRI). Rats received follow-ups for 30 weeks. A double-blinded histological analysis was performed in the esogastric segments. RESULTS BR was diagnosed in OAGB/MGB and EJ rats using the MRI technique; no BR occurred in the sham group. After a 30-week follow-up, no incidences of dysplasia or cancer were observed in the three groups. Additionally, esophageal intestinal metaplasia and mucosal ulcerations were observed in 41.7% and 50% of EJ rats, respectively, and no incidences of these conditions were observed in OAGB/MGB and sham rats. The incidence of esophagitis was significantly higher and more severe in the EJ group compared to those in the OAGB/MGB and sham groups (EJ = 100%, OAGB/MGB = 16.7%, sham = 8.3%; p < 0.001). CONCLUSIONS After a 30-week follow-up period, OAGB/MGB rats did not develop any precancerous or cancerous lesions when more than 40% of EJ rats had intestinal metaplasia.

Abstract
BACKGROUND One anastomosis/mini gastric bypass (OAGB-MGB) is now an established bariatric procedure for patients suffering from obesity. The purpose of this review is to evaluate the role of this operation in patients with body mass index (BMI) ≤ 35 kg/m2. METHODS A literature review was performed as per preferred reporting items for systematic reviews and meta-analyses (PRISMA) guidelines. RESULTS This review reports cumulative results of 376 OAGB-MGB procedures with a mean age of 44.28 years and mean BMI of 29.16 kg/m2 (range 22-35). Females represented 67.67% of the patients. The leak rate was 0.27%. The mean follow-up was 32.6 months (6-84 months). The mean operative time was 89.45 min. The median limb length was 120 cm (range 100-200 cm). The mean fasting plasma glucose (FPG) decreased from 196.97 to 103.28 mg/dL. The mean HbA1c came down from 9.13% preoperatively to 6.14% postoperatively. The total cholesterol levels came down from a mean of 197.8 mg/dL preoperatively to 120.6 mg/dL postoperatively. The low-density lipoprotein (LDL) and triglyceride levels came down from 127.7 and 209.3 mg/dL to 81 and 94.8 mg/dL, respectively. Mortality was 0%. Marginal ulceration rate of 6.3% and an anaemia rate of 4.7% were reported. Low albumin was reported in 1 (0.2%) patient. The mean BMI came down to 23.76 kg/m2 at 12 months. CONCLUSIONS We conclude that there is now satisfactory evidence to consider OAGB-MGB as a safe and effective metabolic procedure for diabetic patients with BMI ≤ 35 kg/m2. Randomised studies comparing different bariatric procedures with longer term follow-up are needed.

Abstract
PURPOSE One-anastomosis gastric bypass (OAGB) is an established bariatric procedure performed worldwide. We developed a modification of OAGB leaving a bridge at the cranial 2 cm of the fundus as a gastro-gastric fistula to allow for endoscopic access to the bypassed stomach. We present the preliminary results of 44 patients who underwent this technique in our hospital. METHODS We analyzed, retrospectively, data collected prospectively on 44 patients who underwent our bridged one-anastomosis gastric bypass (BOAGB) procedure between September, 2018 and November, 2020. RESULTS The mean age of the patients was 45.2 ± 9.3 years (range 20-66 years). The mean preoperative body mass index (BMI), weight, and HbA1c values were 41.5 ± 6.4 kg/m2 (range 35-59), 116 ± 22.7 kg, and 8.2 ± 2.1%, respectively. After a median follow-up period of 18 months (11-26 months), the mean postoperative BMI was 28.4 ± 3.2 kg/m2 (range 21-38), the mean total weight loss was 35.8 ± 13.5 kg (range 20-80 kg), and the mean percentage of excess weight loss (%EWL) and the percentage of total weight loss (%TWL) were 79.8 ± 16.1% (range 47-109) and 30.6 ± 6.9% (range 19-48), respectively. The mean postoperative HbA1c level was 6.3 ± 0.9%. There were two early complications (stenosis and bleeding) and one late complication (marginal ulcer). CONCLUSION Patients who underwent BOAGB lost weight similarly to those who underwent OABG as reported in the literature, without an apparent increase in complications related to the technique. Randomized studies with longer term follow-up are needed.

Abstract
INTRODUCTION There is little data on the effect of one anastomosis gastric bypass (OAGB) on haematinics, vitamin D and parathyroid hormone levels. It is further unclear if an OAGB with a bilio-pancreatic limb (BPL) of 150 cm (OAGB-150) would deliver better outcomes than that with a BPL of 200 cm (OAGB-200). MATERIALS AND METHODS We investigated our records to obtain information on patients who underwent an OAGB-200 or OAGB-150 until 31st July 2018 in our unit. RESULTS A total of 405 patients underwent either an OAGB-200 (n = 234) or OAGB-150 (n = 171). The mean age was 46 ± 10.98 years and 276 (68.1%) were females. The mean preoperative weight and the body mass index (BMI) were 139 ± 29.96 kg and 49 ± 8.14 kg/m2 respectively. With OAGB-200, there was a significant increase in anaemia rates at 1 and 2 years compared to preoperative levels with a significant fall in haemoglobin levels. After OAGB-150, there was a significant fall in haemoglobin levels at 1 and 2 years but the increase in anaemia rate was only significant at 2 years. There was a significant increase in PTH levels and the number of abnormal values at 1 and 2 years with OAGB-200. With OAGB-150, PTH changes were significant at 2 years only. CONCLUSION We found that both OAGB-200 and OAGB-150 are associated with a significant increase in anaemia and secondary hyperparathyroidism. Our findings should prompt the evaluation of supplementation protocols with higher dosages than we recommend for iron, folate and calcium. Consideration should also be given to evaluating shorter BPL lengths than 150 cm with OAGB.

Abstract
PURPOSE One anastomosis/mini gastric bypass (OAGB/MGB) is now an established bariatric and metabolic surgical procedure with good outcomes. Despite two recent consensus statements around OAGB/MGB, there are some issues which are not accepted as consensus and need more long-term data and research. MATERIAL AND METHODS After identifying the topic of non-consensus from the two recent OAGB/MGB consensuses, PubMed, Scopus, and Cochrane were searched for articles published by November 2020. RESULTS In this study, we evaluated these non-consensus topics around OAGB/MGB and all related articles on these topics were assessed by authors to have an argument on these items. CONCLUSION There is enough evidence to include OAGB/MGB as an accepted standard bariatric and metabolic surgical procedure. However, long-term data and more research are needed to have a consensus in all aspects including these non-consensus topics.

Abstract
INTRODUCTION One anastomosis gastric bypass (OAGB) has become one of the most commonly performed gastric bypass procedures in some countries. OBJECTIVES To assess how surgeons viewed the OAGB, perceptions, indications, techniques, and outcomes, as well as the incidence of short- and long-term complications and how they were managed worldwide. METHODS A questionnaire was sent to all IFSO members in all 5 chapters to study the pattern of practice and outcomes of OAGB. RESULTS Seven hundred and forty-two surgeons responded. The most commonly performed procedures were sleeve gastrectomy (SG), Roux-en-Y gastric bypass (RYGB), and OAGB. Preoperatively, 70% of the surgeons performed endoscopy routinely. In regards to weight loss, 83% (570 surgeons) responded that OAGB produces better weight loss than SG, and 49% (342 surgeons) responded that OAGB produces better weight loss than RYGB. The most common length of the biliopancreatic limb (BPL) utilized was 200 cm. Sixty-seven percent of surgeons did not measure the total length of the small bowel. In patients with reflux disease and history of smoking, 53% and 22% of surgeons respectively still offered OAGB as a treatment option. Postoperatively, leak was documented in 963 patients, and it was the leading cause for mortality. Leak management was conservative in 35%. Conversion to RYGB was performed in 31%. In 16% the anastomosis was reinforced, 6% of the patients were reversed, and other procedures were performed in 12%. Revision of OAGB for malnutrition/steatorrhea or severe bile reflux was reported at least once by 37% and 45% of surgeons, respectively (200 cm was the most commonly encountered biliopancreatic limb BPL in those revised for malnutrition). Most common strategy for revision was conversion to RYGB (43%), reversal to normal anatomy (32%), shortening of the BPL (20%), and conversion to SG (5%). Nevertheless, 5 out of 98 mortalities (5%) were due to liver failure/malnutrition. CONCLUSION There are infrequent but potentially severe specific complications including malnutrition, liver failure, and bile reflux that may require surgical correction after OAGB.

Abstract
INTRODUCTION The one anastomosis gastric bypass (OAGB) is an effective treatment to induce sustained weight loss in morbidly obese patients. Concerns remain regarding the development of reflux. The aim of this study was to investigate the effect of an "anti-reflux suture" as anti-reflux modification to prevent reflux. METHOD This is a single-center retrospective cohort study of patients who underwent a primary OAGB at the Center Obesity North-Netherlands (CON) between January 2015 and December 2016. Reflux was defined as symptoms of acid/bilious regurgitation or pyrosis. This was consequently asked and reported at each follow-up visit. Outcomes of patients with an anti-reflux suture were compared to those without. RESULTS In 414 (59%) of the 703 included patients, an anti-reflux suture was applied. Follow-up at 3 years was 74%. The incidence of reflux did not differ between patients with or without an anti-reflux suture (57 versus 56%, respectively; P = 0.9). The presence of an anti-reflux suture was significantly associated with a lower incidence of conversion to Roux-en-Y gastric bypass (RYGB) for reflux (OR 0.56, 95%CI 0.34-0.91). Patients preoperatively diagnosed with gastroesophageal reflux disease (GERD) were 5.2 times more likely to need a conversion to RYGB for reflux (95%CI 2.7-10.1). CONCLUSION The presence of preoperative GERD should be weighted heavily in the decision to perform an OAGB as this is a major risk factor for conversion surgery due to reflux. The anti-reflux suture might be a valuable addition to the procedure of the OAGB because it results in fewer conversion surgeries for reflux.

Abstract
BACKGROUND Reoperation is often required after bariatric procedures. Single-anastomosis gastric bypass (SAGB) is increasingly utilized as a primary bariatric procedure. Few series document SAGB as a revisional bariatric procedure. OBJECTIVES To describe our short-term experience with revisional SAGB, focusing on weight loss and reflux symptom outcomes. SETTING Three hospitals in Australia with both private and public (government funded) patients. METHODS We reviewed all revisional SAGB cases from 2012 to 2019 at. Complications were considered significant if they were Clavien-Dindo grade 3a or higher. A phone survey was conducted to assess weight loss outcomes, patient satisfaction, reflux symptoms, and other complications. RESULTS We identified 254 patients who had a revisional bariatric procedure to SAGB (21 previous sleeve gastrectomies and 233 previous adjustable bands), with a mean follow-up of 22 ± 15.6 months (range, 1-55 mo). The mean percentage of excess weight loss was 77% (183 patients, 72%), and the number of patients with follow-ups at 1 and 4 years was 184 (73%) and 35 patients (14%). Within 30 days, there were 29 patients (11%) who required reinterventions (21 endoscopies, 1 interventional radiology procedure, and 7 reoperations) with no deaths. Beyond 30 days, 27 patients (11%) required rerevision to Roux-en-Y gastric bypass for reflux symptoms and 10 (4%) required a laparotomy or laparoscopy for another reason (e.g., bowel obstruction). At a median follow-up of 36.6 months, 87 patients (34%) completed a phone survey, 45 (52%) of whom were taking proton pump inhibitors and 66 patients (76%) of whom were satisfied with their experience. CONCLUSION In our series, revision to SAGB was safe, with low short-term morbidity and favorable weight loss outcomes. However, beyond 1 year, a large proportion of patients experienced severe reflux symptoms and required rerevision.

Abstract
BACKGROUND The one anastomosis gastric bypass (OAGB) was first described in 2001 as a safe and effective procedure that meets the criteria for the "ideal" weight loss operation. However, revisions for malnutrition and liver failure were reported. CASE REPORT We report a patient who was transferred to our institution with protein calorie malnutrition and liver failure after undergoing OAGB. METHODS A 42-year-old morbidly obese female patient underwent a laparoscopic sleeve gastrectomy (LSG) in 2012 followed by conversion to OAGB in 2018 for weight regain at another institution. Nine months after conversion, she was transferred to our institution with dehydration, vomiting, dysphagia, generalized edema, and steatorrhea (7 times/day). She had become wheelchair bound. On examination, there was gross edema, protein-calorie malnutrition, dermatitis, and muscle wasting. She had anemia (8 g/dl) reference range (11.5-15.5 g/dl), bilirubin (1.8 mg/dl) (0.2-1.2 mg/dl), hypoalbuminemia (1.4 g/dl) (3.5-5 g/dl), and elevated international normalized ratio (INR). The patient was admitted to the hospital and was started on total parenteral nutrition (TPN), with thiamine, vitamins, iron injections, and trace mineral replacement. Her course was complicated by multiple episodes of line sepsis and bacteremia. After 6 weeks, we succeeded in raising her albumin to 2.9 g/dl and proceeded with surgery. TECHNIQUE Laparoscopic exploration started with identifying the anatomy and measuring the biliopancreatic limb (BPL = 430 cm) and the common channel (CC = 380 cm). First, we restored the continuity of the small bowel. Then the long gastric pouch was trimmed. Finally, the patient was converted to a Roux-en-Y gastric bypass (RYGB) with a 30 cm BP limb and 70 cm Roux limb. The patient had an uneventful recovery and was discharged home on the fourth postoperative day. At 3 months of follow-up, her symptoms resolved, her laboratory work up normalized, and she regained mobility. CONCLUSION Malnutrition and liver failure after OAGB are not uncommon. It is encountered with configurations of longer BP limb. BPL length of 150 to 200 cm seems to reduce such complications. Preoperative nutritional optimization is key. Conversion to a proximal RYGB is a safe and feasible approach.

Abstract
INTRODUCTION One anastomosis gastric bypass (OAGB) offers favourable weight loss outcomes and is associated with reduced morbidity and mortality when compared to other mainstream bariatric procedures. However, a randomised trial reported a conversion rate to roux-en-Y configuration (RYC) of 3.1%, and some surgeons consider the procedure unsuitable for patients with a preoperative hiatus hernia (HH) or symptoms of gastrooesophageal reflux disease (GORD). METHODS We carried out a retrospective review of patients undergoing OAGB in our institution. Included were all patients on PPI for symptoms of GORD preoperatively, as well as patients with HH or oesophagitis on preoperative endoscopy. We recorded GORD outcomes as well as rates of conversion to RYC in patients. RESULTS Medium term follow up data at 23-28 months was available for 89 patients. Of these, 63 had HH, 34 had preoperative GORD requiring PPI and 9 had confirmed oesophagitis. The conversion rate to RYC was nil (0/63) in patients with HH. At the same time, 14.7% (5/34) of patients with preop GORD on PPI required conversion to RYC at a median time interval of 16 months. In patients already on PPI preoperatively, 16/34 (47.1%) needed to continue on PPI long term. In patients with HH, 20.6% (13/63) suffered de novo GORD symptoms. CONCLUSION OAGB can be offered to patients with HH with acceptable GORD outcomes but caution is advised in patients with preoperative GORD symptoms. Larger prospective and randomised studies are required to further assess this subgroup.

Abstract
PURPOSE OF REVIEW This review was conducted to gain insight into the history, present and future of bariatric and/or metabolic surgery and endoscopic treatments of obesity. The challenges that have been overcome, the challenges we still face and our recommendations for the future are discussed. RECENT FINDINGS Over the last few decades, a number of treatment strategies have emerged for the treatment of obesity. Both endoscopic and surgical options are available and they lead to significant weight loss and comorbidity reduction. However, to remain a credible treatment alternative to the obesity pandemic, we need to perform these procedures in much larger numbers than we currently do. Even though significant gains have been made in reducing the morbidity and mortality of surgical interventions, there is further room for improvement, especially when it comes to long-term issues. Due to its impact on almost every single organ system in the human body, bariatric surgery has attracted the attention of academics from a variety of medical disciplines. This has led to a rapidly enlarging body of high-quality scientific literature, supporting its wider use and cost-effectiveness. CONCLUSION Despite the advances made in bariatric surgery, the criteria determining suitability of patients for bariatric surgery in most parts of the world are still based on a consensus agreed upon in the USA in 1991. There is a need to formulate some new consensus and guidelines that would allow for a significant expansion of the pool of patients that can be offered these procedures.

Abstract
Among the advantages of the One Anastomosis Gastric Bypass (OAGB) are the lack of jejuno-jejunal anastomosis and a supposed lower incidence of internal hernia (IH), with only a few cases reported until now. However, the incidence of IH after OAGB is not null. We present a video of the laparoscopic management of an IH that occurred after an OAGB. The patient was a 49-year-old female who had undergone a laparoscopic revisional OAGB 2 years previously after a failed laparoscopic adjustable gastric banding. She was referred to our Unit for recurrent postprandial colicky pain. She lost a total of 50 kg and her body mass index (BMI) dropped from 38 to 19 kg/m2. A CT scan with intravenous contrast showed a swirl of the mesentery around the superior mesenteric artery, without small bowel obstruction. A laparoscopic exploration was performed, confirming the suspicion of IH at the Petersen's space. An anticlockwise derotation of the whole common limb was performed, and the Petersen's space was eventually closed with a running non-absorbable suture.

Abstract
BACKGROUND One-anastomosis gastric bypass with band-separated gastric pouch (OAGB-BSGP) is a novel "staplerless" version of OAGB. This randomized controlled trial (RCT) compared 2-year outcomes for OAGB-BSGP and standard OAGB. METHODS The parallel-group RCT randomly allocated patients to group A, staplerless OAGB-BSGP, or group B, stapled OAGB. RESULTS Respective mean values for groups A and B (n = 40 each): baseline body mass index (BMI, kg/m2), 40.6 ± 5.6 vs 41.2 ± 6.4 (p = 0.64); abdominal bleeding (mL), 5.9 ± 8.0 vs 31.1 ± 30.5 (p < 0.0001). Two-year outcomes: BMI, 26.3 ± 3.2 vs 29.0 ± 4.7; %TWL, 34.1 ± 9.0 vs 29.3 ± 10.6, p < 0.03; %EBMIL, 94.3 ± 23.6 vs 77.9 ± 29.3, p < 0.007; bile reflux, n = 1 (2.5%) vs n = 7 (17.5%) (p = 0.05); revisions, n = 0 vs n = 4 (10.0%), p = 0.12. CONCLUSIONS At 2-year RCT follow-up, staplerless OAGB-BSGP patients had fewer complications, no revisions, and greater weight loss than stapled OAGB patients.

Abstract
Heterotopic pancreas, is presence of pancreatic tissue outside its normal location without anatomic continuity with the main body of the pancreas. The Heterotopic pancreas can be in the stomach, duodenum, jejunum, or a Meckel diverticulum. This is the first reported case of gastric heterotopic pancreas found during a bariatric surgery procedure.
Introduction Heterotopic pancreas, also known as ectopic pancreas, is defined as the presence of pancreatic tissue outside its normal location and without anatomic and vascular continuity with the main body of the pancreas. The incidence of heterotopic pancreas has been reported as 0.5 % during laparotomies and at autopsy ranging from 0.6–14 %. Presentation of case A 28 years old obese male, medically free electively admitted for laparoscopic sleeve gastrectomy. Intraoperatively after dissecting the greater omentum from the stomach and inserting the 36 Fr gastric bougie, small oval shape mass about 1 cm close to the lesser curvature on the anterior surface of the gastric antrum. Macroscopically benign looking and a thorough laparoscopic exploration showed no signs of other organs involvement. Antrectomy and mini gastric bypass done. The postoperative course was uneventful. The histopathological examination of the antrectomy specimen showed heterotopic pancreas in the subserosa of gastric antrum. Discussion The Heterotopic pancreatic tissue can be discovered in the stomach (particularly antrum), duodenum, jejunum, or a Meckel diverticulum. Surgical resection is the mainstay treatment if the heterotopic pancreas is symptomatic or when the lesion is found incidentally during surgery in order to prevent complications. Conclusion Heterotopic pancreas should always be considered in the differential diagnosis of incidentally found gastric lesions and can be safely resected. This is the first case report of gastric heterotopic pancreas which is found incidentally during a bariatric surgery procedure.

Abstract
Gastrobronchial fistula is uncommon with an ambiguous presentation. It should be suspected among patients who underwent bariatric surgery. Optimal management is yet to be determined.
Introduction With the high rates of obesity worldwide, laparoscopic sleeve gastrectomy (LSG) has become a very popular procedure. Due to its simple technique, rare complications might be overseen. Gastric leaks and fistula are fairly uncommon complications. In comparison to other types of fistulas, gastrobronchial fistulas are rarer with serious complications. Definitive management is yet to be determined. We intend to explore the literature on the management approach of such patients. Presentation of case A 46-year-old male, presented with on/off abdominal pain, productive cough, and vomiting. The patient had left sided rhonchi on examination. In addition to a history of laparoscopic sleeve gastrectomy (LSG) 4 years ago. Imaging confirmed the presence of a gastrobronchial fistula. Conservative and endoscopic treatment failed. Consecutively, surgery was indicated. A laparoscopic mini gastric bypass with refashioning of gastric fistula edges and closure with graham patch was done. Conclusion Given the increasing number of such surgeries performed the recognition of acute and chronic complications, and their optimal management is of great importance. Although performing a Roux-en-Y fistulojejunostomy was recommended in the literature, conservative and endoscopic treatment should be considered before.

Abstract
BACKGROUND Mini-One Anastomosis Gastric Bypass is a new operation that provides comparable outcomes to the common bariatric procedures. Revisional surgery is still needed after a number of MGB-OAGB procedures. The aim of this study is to report the causes and management of these revisions. METHODS From 2010 to 2018, 925 MGB-OAGB operations were performed at 7 bariatric units across the United Kingdom and included in this retrospective cohort study. The data was retrospectively collected and analysed. The primary end point was the identification of the causes and management of revisions. Follow up ranged from 6 months to 3 years. RESULTS Twenty-two patients [2.3%] required revisional surgery after MGB-OAGB. Five patients [0.5%] developed severe diarrhoea managed by shortening the bilio-pancreatic limb to 150 cm. Four patients [0.4%] developed afferent loop syndrome and bile reflux was reported in another 3 [0.3%] cases; all were managed by either conversion to Roux en Y Gastric Bypass or a Braun anastomosis. Postoperative bleeding was controlled laparoscopically in 3 patients [0.3%]. Liver decompensation that was reported in 2 patients [0.2%] was treated by shortening the BPL in one patient and a reversal to normal anatomy in another. The liver failure resolved in both patients. Other indications for revision included two gastro-jejunal stenosis [0.2%], one perforated ulcer [0.1%], one patient [0.1%] with excessive weight loss and one case [0.1%] of protein malnutrition. None of the 22 patients undergoing revisional surgery after MGB-OAGB died. Lost to follow up rate was 0.2%. CONCLUSION Complications requiring revisional surgery after MGB-OAGB are uncommon [2.3%] and the majority can be managed by bilio-pancreatic limb shortening, the addition of a Braun side-to-side anastomosis or conversion to RYGB. Bilio-pancreatic limb length of 200 cm or more resulted in serious complications of liver failure, protein malnutrition, excessive weight loss and diarrhoea.

Abstract
Cecal volvulus is one of the differential diagnosis of post Mini-gastric bypass acute intestinal obstruction. and pain. Urgent intervention in acute presentation post gastric bypass is the key to saving the patient life and lower morbidity. Conversion of Mini-gastric bypass to Roux-en-Y gastric bypass in any complication surgery is recommended when feasible.
Introduction: With the rising worldwide obesity epidemic, bariatric surgeries are gaining popularity as the most effective modality for achieving long term results in weight loss and reducing its metabolic sequels. Case presentation: A 36-year-old female presented with a sudden onset of severe abdominal pain for 6 h. The patient underwent Mini gastric bypass (MGB) 2 years prior to presentation. Computed tomography (CT) scan revealed a 14-cm dilatation of the cecum occupying the left upper quadrant of the abdomen with the swirling appearance of the mesentery. These findings were confirmed through emergency exploratory laparotomy to be cecal volvulus. a right hemicolectomy and conversion of MGB to a conventional Roux-en-Y gastric bypass. Discussion: a modification of the classical gastric bypass surgery the MGB considered by its advocates to be a safer, simpler, and more effective option. However, serious complications can take place especially in the early learning curve of the procedure. Conclusions We present a unexpected acute in top of chronic cecal volvulus in patient two years post MGB. The uncommon serious complication should be considered one of the differential diagnosis of acute surgical abdomen in those patients.

Abstract
BACKGROUND An increasing number of surgeons worldwide are now performing one anastomosis/mini gastric bypass (OAGB/MGB). Lack of a published consensus amongst experts may be hindering progress and affecting outcomes. This paper reports results from the first modified Delphi consensus building exercise on this procedure. METHODS A committee of 16 recognised opinion-makers in bariatric surgery with special interest in OAGB/MGB was constituted. The committee invited 101 OAGB/MGB experts from 39 countries to vote on 55 statements in areas of controversy or variation associated with this procedure. An agreement amongst ≥ 70.0% of the experts was considered to indicate a consensus. RESULTS A consensus was achieved for 48 of the 55 proposed statements after two rounds of voting. There was no consensus for seven statements. Remarkably, 100.0% of the experts felt that OAGB/MGB was an "acceptable mainstream surgical option" and 96.0% felt that it could no longer be regarded as a new or experimental procedure. Approximately 96.0 and 91.0% of the experts felt that OAGB/MGB did not increase the risk of gastric and oesophageal cancers, respectively. Approximately 94.0% of the experts felt that the construction of the gastric pouch should start in the horizontal portion of the lesser curvature. There was a consensus of 82, 84, and 85% for routinely supplementing iron, vitamin B12, and vitamin D, respectively. CONCLUSION OAGB/MGB experts achieved consensus on a number of aspects concerning this procedure but several areas of disagreements persist emphasising the need for more studies in the future.

Abstract
BACKGROUND In recent years, several articles have reported considerable results with the Mini/One Anastomosis Gastric Bypass (MGB/OAGB) in terms of both weight loss and resolution of comorbidities. Despite those positive reports, some controversies still limit the widespread acceptance of this procedure. Therefore, a multicenter retrospective study, with the aim to investigate complications following this procedure, has been designed. PATIENTS AND METHODS To report the complications rate following the MGB/OAGB and their management, and to assess the role of this approach in determining eventual complications related especially to the loop reconstruction, in the early and late postoperative periods, the clinical records of 2678 patients who underwent MGB/OAGB between 2006 and 2015 have been studied. RESULTS Intraoperative and early complications rates were 0.5 and 3.1%, respectively. Follow-up at 5 years was 62.6%. Late complications rate was 10.1%. A statistical correlation was found for perioperative bleeding both with operative time (p < 0.001) or a learning curve of less than 50 cases (p < 0.001). A statistical correlation was found for postoperative duodenal-gastro-esophageal reflux (DGER) with a preexisting gastro-esophageal-reflux disease (GERD) or with a gastric pouch shorter than 9 cm, (p < 0.001 and p = 0.001), respectively. An excessive weight loss correlated with a biliopancreatic limb longer than 250 cm (p < 0.001). CONCLUSIONS Our results confirm MGB/OAGB to be a reliable bariatric procedure. According to other large and long-term published series, MGB/OAGB seems to compare very favorably, in terms of complication rate, with two mainstream procedures as standard Roux-en-Y gastric bypass (RYGBP) and laparoscopic sleeve gastrectomy (LSG).

Abstract
BACKGROUND Mini gastric bypass (MGB) is a promising and attractive alternative bariatric procedure. In 2011, we introduced MGB in our high-volume bariatric unit. Subsequently, we evaluated short- and midterm results of this procedure. METHODS A prospective cohort of patients who underwent MGB between 2012 and 2013 was retrospectively evaluated. RESULTS From 2012 to 2013, primary MGB was performed in 287 patients with a mean BMI of 42 kg/m2 (range 32-76 kg/m2). The mean operation time was 50 min (range 25-120 min). The mortality rate was 0%. Serious complications, such as leakage, pulmonary embolism, or bleeding, occurred in 3.1% of patients; anastomotic leaks occurred in 1.4% of patients. Conversion to Roux-en-Y gastric bypass for biliary reflux or other indications occurred in six patients (2%). During our initial learning phase, biliary reflux rates were higher due to an overly short pouch. Surgical revision for malnutrition was performed in one patient. Percent excess weight loss and percent total body weight loss were 85 and 35%, respectively, after 1 year; 88 and 36.6%, respectively, after 2 years; and 83 and 34.3%, respectively, after 3 years. Follow-up rates after 1, 2, and 3 years were 96% (277/287), 72% (208/287), and 66% (190/287), respectively. CONCLUSIONS As a primary bariatric procedure, MGB is associated with good early and midterm results. MGB has the potential to become a significant alternative bariatric procedure. Correct technique is of extreme importance when performing MGB; therefore, the appointment of an experienced MGB surgeon as a guide when beginning to utilize this technique is advised.

Abstract
BACKGROUND Omega loop gastric bypass (OLGB) has been viewed with skepticism after the failure of the "old Mason loop." During the past 15 years, a growing number of authors worldwide approved that OLGB is a safe and effective procedure, which appears clearly from the operative outcome and long-term follow-up of consecutive cohort studies of patients who underwent OLGB. The aim of this study is to evaluate the outcomes of OLGB at the bariatric center of our university hospital between 2009 and 2015. METHODS The data of 1520 patients who underwent OLGB from November 2009 to December 2015 at our center were reviewed. Mean age was 37.15 years, mean preoperative BMI was 46.8 ± 6.6 kg/m2, mean preoperative weight was 127.4 ± 25.3 kg, and 62.7% were women. Diabetes mellitus (DM) affected 683 (44.9%) of the 1520 patients, whereas 773 of the 1520 patients (50.9%) presented with hypertension. The mean operative time was 35 min. RESULTS The 1-year postoperative BMI mean decreased to 29.6 ± 3.1 kg/m2, and at the 3-year follow-up, it was 27.5 ± 3.4 kg/m2. The mean of weight decreased to 81.3 ± 16.7 kg and to 78.9 ± 16.9 kg at the 1-year and the 3-year follow-up, respectively. Mortality rate was 0.1%. Overall complications were 9.3%; 0.8% required reoperations. Early complications were encountered in 50 patients (3.3%), and the late complications rate was (6.1%). CONCLUSIONS In this study, greater excess weight loss was observed with OLGB which appeared to be a short, simple, low-risk, effective, and durable bariatric procedure.

Abstract
INTRODUCTION One anastomosis gastric bypass (OAGB) demonstrated results similar to traditional Roux-en-Y procedures [1-3], in terms of weight loss and resolution of obesity-related comorbidities. The main controversy regarding OAGB is the concern for an association between biliary alkaline gastritis and esophageal or gastric cancer raised by some studies [4]. METHODS We present the case of a 51-year-old woman with a BMI of 41 kg/m2 who underwent a laparoscopic OAGB in 2014. One year later, she consulted for recurrent heartburns. An upper GI endoscopy showed pouchitis and bile reflux in the esophagus. Medical treatment of gastroesophageal reflux disease was ineffective. We decided to convert the OAGB to a Roux-en-Y gastric bypass (RYGB). RESULTS In this video, we show how to revise an OAGB to treat chronic bile reflux, by converting the procedure to a standard RYGB. The intervention starts by restoring the normal anatomy of the small bowel, with the resection of the gastrojejunal anastomosis, which was located at 250-cm du Treitz's ligament. Then, the gastric pouch is created. A standard Roux-en-Y gastric bypass is performed. CONCLUSIONS The resection of the gastrojejunal anastomosis allows fashioning the Roux-en-Y limb with the classical measures. This technique allows a conversion to a standard RYGB and is effective in treating the biliary reflux.

Abstract
Management of super-super obese patients poses a particular challenge for bariatric surgeons. Many staged algorithms exist for these patients. Essentially all of these involve a lower-risk procedure like sleeve gastrectomy first before a definitive second-stage procedure like gastric bypass or duodenal switch. This study compares our results with 19 mini (one anastomosis) gastric bypass and 56 sleeve gastrectomy in super-super obese patients. Sleeve gastrectomy patients were significantly older. There was no mortality or major complication in either group. There was no minor complication in mini (one anastomosis) gastric bypass group compared to two in the sleeve gastrectomy group. Mini (one anastomsosis) gastric bypass patients experienced significantly higher weight loss compared to sleeve gastrectomy patients at 6 months, 1 year, and 2 years after surgery.

Abstract
BACKGROUND Diabetes and other obesity-related diseases are a worldwide pandemic that transcends geographic borders as well as socioeconomic levels. Currently, it is well known that medical treatment alone is insufficient to ensure adequate and sustainable weight loss and co-morbidity resolution. It has been well proven that bariatric surgery can produce almost immediate resolution of diabetes and other co-morbidities as well as long-term weight loss. OBJECTIVES Here, we present our experience with the one anastomosis gastric bypass (OAGB) in terms of weight loss and diabetes resolution with 1 year of follow-up. SETTING Large, metropolitan, tertiary, university hospital. METHODS A retrospective analysis of all patients who underwent OAGB between March 2015 and March 2016 was performed. Patient demographic characteristics, co-morbidities, operative and postoperative data, as well as first year outcomes were collected and analyzed. RESULTS There were 407 patients who underwent OAGB (254 females, average age 41.8 ± 12.05 yr, body mass index = 41.7 ± 5.77 kg/m2). Of patients, 102 (25.1%) had diabetes with average glycosylated hemoglobin of 8.64 ± 1.94 g%, 93 (22.8%) had hypertension, 123 (28.8%) had hyperlipidemia, and 35 patients (8.6%) had obstructive sleep apnea. The average length of hospital stay was 2.2 ± .84 days (range, 2-10 d). The average excess weight loss 1 year after surgery was 88.9 ± 27.3. After 1 year, follow-up data were available for more than 85% of the study's general population. Of 102 diabetic patients, only 8 (7.8%) were still considered diabetic and taking antidiabetic medication, with an average glycosylated hemoglobin of 5.4 ± 0.6. CONCLUSIONS OAGB may be performed safely and with promising efficacy as both a primary and a revisional bariatric surgery, and it offers excellent resolution of diabetes.

Abstract
BACKGROUND Evaluation of the prevalance of cholelithiasis, choledocholithiasis and there management after sleeve gastrectomy, gastric bypass and mini gastric bypass in Indian bariatric patients. METHODS We did a retrospective analysis of our bariatric patient from January 2007 to December 2013 (n = 1397), for prevalence of cholelithiasis and choledocholithiasis. We did synchronous cholecystectomy in all patients planned for bariatric surgery found to have cholelithiasis on USG. Post-operatively, we followed all the patients with gallbladder in situ for minimum of 18-88 months (mean -32.4) and reviewed data for subsequent development of cholelithiasis/choledocholithiasis. Only those patients who were symptomatic underwent intervention. RESULTS Prevalence of cholelithiasis and choledocholithiasis in our study was 21.76 and 9.63 %, respectively. The incidence of post-bariatric surgery development of cholelithiasis was 10.53 %; individually, it was 8.42 % in LSG group, 13.4 % in LRYGB group and 12.7 % in MGB patients. The incidence of symptomatic cholelithiasis requiring surgery was 1.94 % after LSG, 4.54 % after LRYGB and 4.25 % after MGB. Post-surgery, six patients developed choledocholithiasis. In our post-bariatric group, the 33 patients who developed symptomatic stones had percentage total weight loss of 30.99 + 4.1 (P < 0.001). The average time period for readmission of symptomatic patient was 11.26 + 2.67 months. CONCLUSIONS We recommend routine synchronous cholecystectomy with bariatric procedure. In spite of synchronous cholecystectomy, incidence of cholelithiasis in our post-bariatric patient is 10.53 % of which up to one third were symptomatic and required surgery, and incidence of choledocholithiasis is comparable to that of general population.

Abstract
INTRODUCTION There is reluctance amongst many healthcare professionals to offer bariatric surgery to septuagenarians. There is only one study in the scientific literature specifically describing any experience with this group of patients and none that compares the outcomes in this group with younger patients. METHODS We retrospectively examined our prospective database to identify all those who were >70 years old at the time of bariatric surgery. This group was then compared with a matched (for sex, body mass index, surgical procedure, and time of surgery) cohort of younger (<60 year old) patients. Information was obtained from our database, case notes, hospital electronic records, by interviewing team members, and from general practitioners. RESULTS A total of 10 septuagenarians were compared with 10 younger patients (mean age 41 years). There were one early complication and 1 late complication in the over 70 group as opposed to no early complication and 2 late complications in the younger group. There was no mortality or early reoperation in either group. Excess weight loss of 50.4, 67.4, and 74.0% in the >70 age group at 6, 12, and 24 months, respectively, was no different to 51.3, 70.8, and 73.9% in <60 year olds. The effect on the co-morbidity resolution was similar in the two groups. CONCLUSION In carefully selected septuagenarians, bariatric surgery can be performed with safety and efficacy comparable to those <60 years old.

Abstract
Background Laparoscopic Roux-en-Y gastric bypass (LRYGB) is considered the gold standard in bariatric surgery, achieving durable long-term weight loss with improvement of obesity-related comorbidities. Lately, the laparoscopic mini gastric bypass (LMGB) has gained worldwide popularity with similar results to LRYGB in terms of weight loss and comorbidity resolution. However, there is a lack of randomized controlled trials (RCT) comparing LMGB and LRYGB. This article describes the design and protocol of a randomized controlled trial comparing the outcomes of these two bariatric procedures. Methods/Design The trial is designed as a single center, randomized, patient and observer blinded trial. The relevant ethics committee has approved the trial protocol. To demonstrate that LMGB is not inferior to LRYGB in terms of excess weight loss (EWL) the study is conducted as a non-inferiority trial with the sample-size calculations performed accordingly. EWL 12 months after surgery is the primary endpoint, whereas 3-year EWL, morbidity, mortality, remission of obesity related comorbidities, quality of life (QOL) and hormonal and lipid profile changes are secondary endpoints. Eighty patients, 18 years or older and with a body mass index (BMI) between 35 and 50 kg/m2 who meet the Swiss guidelines for the surgical treatment of morbid obesity will be randomized. The endpoints and baseline measurements will be assessed pre-surgery, peri-surgery and post-surgery (fixed follow up measurements are at discharge and at the time points 6 weeks and 12 and 36 months postoperatively). Discussion With its 3-year follow up time, this RCT will provide important data on the impact of LMGB and LRYGB on EWL, remission of comorbidities, QOL and hormonal and lipid profile changes. Trial registration ClinicalTrials.gov, NCT02601092. Registered on 28 September 2015.

Abstract
Our aim is to present the laparoscopic technique of an emergency revisional procedure performed to convert a mini/one anastomosis gastric bypass (MGB/OAGB) to a modified Roux-en-Y-gastric-bypass (RYGB) due to recurrent bleeding from a marginal ulcer. A 43 year old woman presented unstable conditions due to acute bleeding from a marginal ulcer after a MGB/OAGB performed 3 years before. After three failed endoscopic haemostasis attempts, she underwent a laparoscopic conversion to a modified RYGB in emergency setting. The patient had an uneventful recovery. She maintained heamodynamical stability after the procedure. She was eventually discharged in the seventh postoperative day after restarting oral feeding on chronic proton pump inhibitors. To our knowledge, there are few descriptions of emergency surgical conversion from a MGB/OAGB to a modified laparoscopic RYGB due to a recurrent marginal ulcer bleeding not responsive to endoscopic treatment. A regular post-operative follow-up is mandatory after bariatric surgery. We advocate performing revisional surgery in an experienced Bariatric Center.

Abstract
Obesity has been a problem since medieval times, but only in the latter 20 years it has been recognized as a worldwide epidemic. Treating obesity is challenging and difficult, but surgery has led to an increased success and novel insights on the pathophysiology of obesity. Several surgical techniques have been developed during the last 50 years and the advent of laparoscopic surgery has increased its safety, efficacy and demand from the population. Nowadays, the ever increasing and successful use of novel techniques have been responsible for several changes in the established treatment paradigms.

Abstract
PURPOSE Sleeve gastrectomy (LSG) and mini gastric bypass (LMGB) was considered as emerging procedures but are now considered for many authors as an alternative of the Roux-Y gastric bypass because of similar percentages of weight loss and better postoperative morbidity profiles. However, studies comparing LSG and LMGB are scarce. MATERIALS AND METHODS From January 2010 to July 2014, 262 and 161 patients underwent LSG or LMGB in two centre of bariatric surgery, respectively. At one year, rate of follow-up was 88.4%. Main outcome was % of Total Weight Loss (%TWL) at one year. Propensity score matching and multivariable analyses were used to compensate for differences in some baseline characteristics. RESULTS After matching LSG (N = 136) and LMGB (N = 136) groups did not differ for initial BMI (kg/m(2)) (43.4 ± 6.5 vs. 42.8 ± 5.0; P = 0.34), % of female patients (91.9% vs. 93.4%; P = 0.64), age (years) (41.2 ± 12.3 vs. 41.2 ± 11.3; P = 0.99) and diabetes (15.4% vs. 19.9%; P = 0.34). At one year, %TWL, change in BMI and rate of stenosis were higher for LMGB group, respectively: 38.2 ± 8.4 vs. 34.3 ± 8.4 (P < 0.0001); -16.5 ± 4.6 vs. -14.9 ± 4.4 (P = 0.005) and 16.9% vs. 0% (P < 0.0001). In multivariate analyses (β coefficient), LMGB was a positive independent factor of %TWL (2.8; P = 0.008). CONCLUSION LMGB seems to have better weight loss at one year compared to LSG with higher gastric complications. Further long term studies are needed.

Abstract
OBJECTIVES Despite the initial effectiveness of sleeve gastrectomy (SG), some patients who undergo this purely restrictive technique have inadequate weight loss or renewed weight gain and persistent obesity-related co-morbidities with their potentially lethal complications. In such patients, the conversion of SG by the addition of a malabsorptive technique may then be necessary. PATIENTS AND METHODS Conversion of SG to a mini gastric bypass (MGBP) was evaluated for failure of weight loss. An ante-colic end-to-side stapled gastro-jejunal anastomosis was performed laparoscopically, connecting the long narrow gastric tube to the jejunum at a point 200cm downstream from the ligament of Treitz. RESULTS Between October 2006 and February 2012, 651 laparoscopic MGBP were performed for morbid obesity. Twenty-three of these patients (3.5%) had previously undergone SG. The conversion from SG to MGPB was performed laparoscopically in 19 of the 23 patients (81%) at a mean interval of 26.3months (8.2-63.7). The 30-day postoperative mortality rate was zero and the morbidity rate was 9.5%. The mean BMI before MGBP was 44±7.7kg (35.8-55.4). Conversion of SG to MGBP resulted in additional weight loss, achieving a mean BMI of 39.9 with a 26.8% loss of excess BMI (EBL) at 3months, mean BMI of 36.5 with 37.2% EBL at 12months, mean BMI of 36.2 with 48.6% EBL at 18months, and mean BMI of 35.7 with EBL of 51.6% at 24months. The overall mean EBL was 57.3±19.5% (range: 25-82%) at 42.3months (range 16.7-60.8months). CONCLUSION Conversion of SG to MGBP is feasible, safe and effective, and results in significant additional weight loss. Definitive results at 2 and 5years are awaited for the long-term procedure validation.
