IntroductionGastric 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.MethodLiterature 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.ResultsThere were selected 35 studies that matched the headings. Late complications were considered as: anastomotic strictures, marginal ulceration and gastrogastric fistula.ConclusionKnowledge 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.

Since its appear in the year 1997, when Drs. Cadiere and Himpens did the first robotic cholecystectomy in Brussels, not long after the first cholecystectomy, they performed the first robotic bariatric procedure. It is believed that robotically-assisted surgery’s most notable contributions are reflected in its ability to extend the benefits of minimally invasive surgery to procedures not routinely performed using minimal access techniques. We describe the 3 most common bariatric procedures done by robot. The main advantages of the robotic system applied to the gastric bypass appear to be better control of stoma size, avoidance of stapler costs, elimination of the potential for oropharyngeal and esophageal trauma, and a potential decrease in wound infection. While in the sleeve gastrectomy and adjustable gastric banding its utility is more debatable, giving a bigger advantage during surgery on patients with a very large BMI or revisional cases.
