Silecchia, GianfrancoIossa, AngeloWith over 600 million people being obese, and given the scientific demonstration of the advantages of surgical treatment, bariatric surgery is on the rise. The promising long-term results in terms of weight loss, and particularly in relation to comorbidities and the control/cure rate, mean that the number of procedures performed in all countries remains high. However, the risk of potentially complex or fatal complications, though small, is present and is related to the procedures per se. This review is a guide for bariatric and/or general surgeons, offering a complete overview of the pathogenesis of anastomosis and staple line following the most common laparoscopic bariatric procedures: sleeve gastrectomy, gastric bypass, and mini-gastric bypass. The review is divided according to the procedure and the complications (leak, bleeding and stenosis), and evaluates all the factors that can potentially improve or worsen the complication rate, representing a "unicum" in the present literature on bariatric surgery.Keywords Bariatric surgery, complications, laparoscopic, staple line, prevention, leaks, stenosis, bleedingAnn Gastroenterol 2018; 31 (1): 56-64text/htmlapplication/pdfhttp://www.annalsgastro.gr/index.php/annalsgastro/article/view/3462engHellenic Society of Gastroenterology1792-74631108-7471Annals of Gastroenterology; Volume 31, No 1 (2018); 56Complications of staple line and anastomoses following laparoscopic bariatric surgeryinfo:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersion2017-12-30Δημοσίευση σε περιοδικόPublication in journalΓαστροεντερολογίαGastroenterologyisi -Gastroenterology & Hepatology covers resources on the anatomy, physiology, biochemistry, and pathology of the digestive system.
