The number of obese individuals worldwide continues to increase every year, thus, the number of bariatric/metabolic operations performed is on a constant rise as well. Beside exclusively restrictive procedures, most of the bariatric operations have a more or less malabsorptive component. Several different bypass procedures exist alongside each other today and each type of bypass is performed using a distinct technique. Furthermore, the length of the bypassed intestine may differ as well. One might add that the operations are performed differently in different parts of the world and have been changing and evolving over time. This review evaluates the most frequently performed bariatric bypass procedures (and their variations) worldwide: Roux-en-Y Gastric Bypass, One-Anastomosis Gastric Bypass, Single-Anastomosis Duodeno-Ileal Bypass + Sleeve Gastrectomy, Biliopancreatic Diversion + Duodenal Switch and operations due to weight regain. The evaluation of the procedures and different limb lengths focusses on weight loss, remission of comorbidities and the risk of malnutrition and deficiencies. This narrative review does not aim at synthesizing quantitative data. Rather, it provides a summary of carefully selected, high-quality studies to serve as examples and to draw tentative conclusions on the effects of the bypass procedures mentioned above. In conclusion, it is important to carefully choose the procedure and small bowel length excluded from the food passage suited best to each individual patient. A balance has to be achieved between sufficient weight loss and remission of comorbidities, as well as a low risk of deficiencies and malnutrition. In any case, at least 300 cm of small bowel should always remain in the food stream to prevent the development of deficiencies and malnutrition.

IntroductionDespite the non-negligible weight loss failure rate at midterm, Roux-en-Y gastric bypass (RYGB) remains the reference procedure in the treatment of morbid obesity with metabolic comorbidities. A recently emerged procedure, the single anastomosis duodeno–ileal bypass with sleeve gastrectomy (SADI-S), could be more effective on weight loss with similar morbidity and lower weight loss failure rate than RYGB. We propose the first randomised, open, multicentre superiority trial comparing the SADI-S to RYGB (SADISLEEVE).Methods and analysisThe main objective is to demonstrate the superiority at 2 years after surgery of the SADI-S compared with RYGB in term of excess weight loss percentage. The secondary objectives are the evaluation of nutritional status, metabolic outcomes, overall complication rates and quality of life, within 2 years after surgery. Key inclusion criteria are obese patients with body mass index (BMI) ≥40 kg/m2 or ≥35 kg/m2 with at least one comorbid condition and candidate to a first bariatric procedure or after failure of sleeve gastrectomy. Patients randomised by minimisation in two arms, based on centre, surgery as a revisional procedure, presence of type 2 diabetes and BMI >50 kg/m2 will be included over 2 years.A sample size of 166 patients in each group will have a power of 90% to detect a probability of 0.603 that excess weight loss in the RYGB arm is less than excess weight loss in the SADI-S arm with a 5% two-sided significance level. With a drop-out rate of 10%, it will be necessary to include 183 patients per group.Ethics and disseminationThe study was approved by Institutional Review Board of Centre Hospitalier Universitaire Morvan (CPP1089-HPS1). Study was also approved by the French national agency for drug safety (2018061500148). Results will be reported in peer-reviewed scientific journals.Trial registration numberNCT03610256.

Abstract Background The need for revisional procedures after sleeve gastrectomy (SG) for insufficient weight loss or weight regain, gastroesophageal reflux, or other complications is reported to be 18–36% in studies with 10-year follow-up. Single-anastomosis duodeno-ileal bypass (SADI) may be performed as a revisional procedure after SG. This study aims to evaluate the short- and mid-term outcomes of SADI after SG in a referral center for bariatric surgery. Materials and Methods Data of patients who underwent SADI between March 2015 and March 2020 were collected prospectively and analyzed retrospectively. Follow-up comprised clinical and biochemical assessment at 1, 3, 6, 12, 18, and 24 months postoperatively, and once a year thereafter. Results Overall, 106 patients underwent SADI after a previous SG. The timeframe between SG and SADI was 50 ± 31.3 months. Postoperative mortality was observed in two cases (1.8%) and morbidity in 15.1% of patients. At 24 months, %total weight loss was 37.6 ± 12.3 and %excess weight loss 76.9 ± 25.2 (64 patients). Three patients were treated for malnutrition during follow-up, two with medical treatment and one with SADI reversal. Conclusion SADI after SG provides effective weight loss results in the short-term, even if in the present series the postoperative complication rate was non-negligible. Further trials are needed to establish the more advantageous revisional bariatric procedure after failed SG.

Abstract Background Although the sleeve gastrectomy (SG) has good short-term results, it comes with a significant number of patients requiring revisional surgery because of insufficient weight loss or functional complications. Objective To investigate the effectiveness of the single anastomosis duodenoileal bypass (SADI-S) versus the Roux-en-Y gastric bypass (RYGB) on health outcomes in (morbidly) obese patients who had previously undergone SG, with up to 5 years of follow-up. Methods Data from patients who underwent revisional SADI-S or RYGB after SG were retrospectively compared on indication of surgery, weight loss, quality of life, micronutrient deficiencies, and complications. Results From 2007 to 2017, 141 patients received revisional laparoscopic surgery after SG in three specialized Dutch bariatric hospitals (SADI-S n=63, RYGB n=78). Percentage total weight loss following revisional surgery at 1, 2, 3, 4, and 5 years was 22%, 24%, 22%, 18%, and 15% for SADI-S and 10%, 9%, 7%, 8%, and 2% for RYGB (P<.05 for 1–4 years). Patients who underwent RYGB surgery for functional complications experienced no persistent symptoms of GERD or dysphagia in 88% of cases. No statistical difference was found in longitudinal analysis of change in quality of life scores or cross-sectional analysis of complication rates and micronutrient deficiencies. Conclusion Conversion of SG to SADI-S leads to significantly more total weight loss compared to RYGB surgery with no difference in quality of life scores, complication rates, or micronutrient deficiencies. When GERD in sleeve patients has to be resolved, RYGB provides adequate outcomes. Graphical abstract

Abstract Background It is already known that Laparoscopic sleeve gastrectomy (LSG) has gained popularity as a stand-alone procedure with good short-term results for weight loss. However, in the long-term, weight regain is considered as a complication. Demand for secondary surgery is rising, partly for this reason, but through that study we try to discover the efficacy of conversion of failed sleeve gastrectomy to one anastomosis gastric bypass (OAGB) regarding weight loss and metabolic outcomes. Objective To asses the efficacy and safety of one anastomosis gastric bypass (OAGB) as a conversion surgery post Sleeve Gastrectomy failure as regard weight loss and metabolic outcomes. Patients and Methods This study is a retrospective cohort study which included 20 patients underwent one anastomosis gastric bypass at Ain-Shams University El-Demerdash Hospital, Cairo, Egypt and specialized bariatric center, Cairo, Egypt From February 2019 to July 2019 with 6 months of postoperative follow up till January 2019. Results In this study, we reviewed and analyzed the outcomes from the revision of the SG due to either inadequate weight loss or weight regain to one anastomosis gastric bypass (OAGB) with %EBWL of 6.65% at 1 month, 13.61 % at 3 months and 20.86% at 6 months. Conclusion OAGB appears to be an effective and safe therapeutic technique as a revisional surgery for failed primary SG with good short-term results for treating morbid obesity and its associated comorbidities with a significantly low rate of complications. However the EBWL was less than what is reported after primary OAGB weight. Multicenter studies with larger series of patients and longer term follow up after SG revisions to OAGB are warranted.

The field of endoscopic bariatric and metabolic therapy has rapidly evolved from offering endoscopic treatment of weight regain following bariatric surgery to providing primary weight loss options as alternatives to pharmacologic and surgical interventions. Gastric devices and remodeling procedures were initially designed to work through a mechanism of volume restriction, leading to earlier satiety and reduced caloric intake. As the field continues to grow, small bowel interventions are evolving that may have some effect on weight loss but focus on the treatment of obesity-related comorbidities. Future implementation of combination therapy that utilizes both gastric and small bowel interventions offers an exciting option to further augment weight loss and alleviate metabolic disease. This review considers gastric devices and techniques including space-occupying intragastric balloons, aspiration therapy, endoscopic tissue suturing, and plication interventions, followed by a review of small bowel interventions including endoluminal bypass liners, duodenal mucosal resurfacing, and endoscopically delivered devices to create incisionless anastomoses. Expected final online publication date for the Annual Review of Medicine, Volume 73 is January 2022. Please see http://www.annualreviews.org/page/journal/pubdates for revised estimates.
