Laparoscopic sleeve gastrectomy operations performed for morbid obesity are among the most common methods in the world. Gastric or intestinal bypass surgery with or without sleeve gastrectomy is thought to be more effective in controlling both weight loss and metabolic diseases. For this purpose, Roux-en-y gastric bypass, transit bipartition, duodenal switch, jejunoileal bypass are performed. The aim of this study was to evaluate the effects of jejunoileal bypass surgery on weight loss and metabolic diseases in patients with sleeve gastrectomy.

Bariatric surgery results in more and more long-term weight loss than traditional treatment in moderate and severe obesity. Due to morbid obesity, jejunoileal bypass has been applied since 1970. Laparoscopic sleeve gastrectomy and jejunoileal anastomosis are among the rare techniques described in 2012. There are few studies on this technique.

Between 2015 and 2018, jejunoileal bypass operations with laparoscopic sleeve gastrectomy for morbid obesity will be evaluated in Inonu University gastroenterology surgery clinic. The patients' age, gender, body mass index, weight loss in follow-up periods, whether there is back weight gain, the effects on metabolic diseases, early and late complications will be evaluated.

Inclusion Criteria:All patients who underwent the sleeve gastrectomy with jejunoileal bypass between 2015-2018 for the treatment morbid obesity

Exclusion Criteria:other operations for morbid obesity except sleeve gastrectomy with jejunoileal bypass

Patients aged between 18 and 60 years with a body mass index greater than 40, no comorbidity or a body mass index of 35-40, with a comorbidity (diabetes mellitus, hypertension, obstructive sleep apnea)
