INTRODUCTION: Gastric bypass is today the most frequently performed bariatric procedure, but, despite of it, several complications can occur with varied morbimortality. Probably all bariatric surgeons know these complications, but, as bariatric surgery continues to spread, general surgeon must be familiarized to it and its management. Gastric bypass complications can be divided into two groups: early and late complications, taking into account the two weeks period after the surgery. This paper will focus the late ones. METHOD: Literature review was carried out using Medline/PubMed, Cochrane Library, SciELO, and additional information on institutional sites of interest crossing the headings: gastric bypass AND complications; follow-up studies AND complications; postoperative complications AND anastomosis, Roux-en-Y; obesity AND postoperative complications. Search language was English. RESULTS: There were selected 35 studies that matched the headings. Late complications were considered as: anastomotic strictures, marginal ulceration and gastrogastric fistula. CONCLUSION: Knowledge on strategies on how to reduce the risk and incidence of complications must be acquired, and every surgeon must be familiar with these complications in order to achieve an earlier recognition and perform the best intervention.

Search language was English. RESULTS: There were selected 26 studies that matched the headings. Early complications included: anastomotic or staple line leaks, gastrointestinal bleeding, intestinal obstruction and incorrect Roux limb reconstruction. CONCLUSION: Knowledge on strategies on how to reduce the risk and incidence of complications must be acquired, and every surgeon must be familiar with these complications in order to achieve an earlier recognition and perform the best intervention.

IntroductionOne anastomosis gastric bypass (OAGB) has become a widespread technique over the last few years in France, without any prior assessment and despite existing controversies among bariatric surgeons. An older bypass technique for treating obesity, the Roux-en-Y gastric bypass (RYGB), is available and reimbursed, having been assessed and approved for use in 2005. In 2019, the French Haute Autorité de Santé (HAS) assessed OAGB for the treatment of severe and massive obesity. This assessment, the first in the world, was undertaken for OAGBs carried out with a 200- or 150-centimeter biliopancreatic-limb (BP-limb) length.MethodsA systematic review (SR) of the literature and consultation of a working group consisting of both healthcare professionals (clinician and surgeons) and patients were carried out. The primary aim of our assessment was to determine whether the OAGB technique can replace RYGB. The efficacy and safety profile of OAGB was compared with RYGB in adult patients with massive, severe obesity. Complications and postoperative follow up specific to OAGB were identified.ResultsThe three selected randomized controlled trials (RCTs) could not confirm the superiority or the non-inferiority of OAGB, compared with RYGB, on the selected efficacy endpoints of weight loss, resolution of comorbidities, and quality of life. Adverse events reported for OAGB included severe nutritional complications and bile reflux that could potentially lead to lower esophageal cancer. In one RCT, the frequency of serious adverse events in the OAGB group was almost two times higher than in the RYGB group.ConclusionsHAS considered that OAGB carried out with a longer (200 centimeter) BP-limb is not a validated technique for the surgical treatment of massive, severe obesity. Thus, it cannot be considered an alternative to RYGB. There were insufficient data available on OAGB performed with a 150-centimeter BP-limb. Thus, HAS recommended undertaking a multicenter RCT to assess the efficacy and safety of OAGB. Patients who have already undergone OAGB should receive the same follow up as patients who have received RYGB, including close monitoring for nutritional complications and lower esophageal cancer and an endoscopic examination five years after surgery.

Abstract Introduction Obesity increases the risk of pelvic floor disorders in individuals with obesity, including faecal incontinence. Faecal incontinence (FI) is a condition with important clinical and psychosocial consequences. Though it is associated with obesity, the effect of bariatric surgery on the prevalence and severity of FI is not well reported. Objective To assess the effect of bariatric surgery on the prevalence and severity of FI in adult patients with obesity. Methods This systematic review was conducted in accordance with the PRISMA statement. Two independent reviewers performed a literature search in MEDLINE, PubMed, Cochrane and Embase from 1 January 1980 to 12 January 2019. We included published English-language randomized control trials and observational studies assessing pre- and post-bariatric surgery prevalence or severity of FI. Random-effects models with DerSimonian and Laird’s variance estimator were used for meta-analysis. Results Thirteen studies were included, eight assessing prevalence (678 patients) and 11 assessing severity of FI (992 patients). There was no significant difference in prevalence post-operatively overall, though it trended towards a reduction [pooled OR=0.55; =0.075]. There was a significant reduction of FI prevalence in women post-bariatric surgery [95% CI 0.22 to 0.94, p=0.034]. There was a statistically significant reduction in FI prevalence following Roux-en-Y gastric bypass and one anastomosis gastric bypass [0.46, 95% CI 0.26 to 0.81; p=0.007]. There was no significant reduction of incontinence episodes post-operatively [pooled mean difference =−0.17, 95% CI −0.90 to 0.56; p=0.65]. Quality of life (QOL) was not significantly improved post-bariatric surgery [mean differences for the following facets of QOL: behaviour −0.35, 95% CI −0.94 to 0.24; depression 0.04, 95% CI −0.12 to 0.2; lifestyle −0.33, 95% CI −0.98 to 0.33; p values of 0.25, 0.61 and 0.33, respectively]. Discussion There was a significant reduction in FI prevalence in women and those who underwent Roux-en-Y or one anastomosis gastric bypass. Our results for FI prevalence overall, FI severity and impact on quality of life were not statistically significant. Larger studies are needed in this under-researched area to determine the true effect of bariatric surgery on FI. Graphical abstract
