Sleeve gastrectomy is an established therapeutic option for morbidly obese patients without preexisting gastroesophageal reflux disease. The novel single anastomosis sleeve ileal bypass (SASI) procedure is already introduced in Norway at a private high-volume bariatric hospital. The purpose of this study is to evaluate the effects of SASI in comparison to an established bariatric procedure, i.e. sleeve gastrectomy. The primary end point is 2-year changes in BMI after sleeve gastrectomy and SASI.
This study will compare two bariatric surgical interventions in terms of weight loss, gastroesophageal reflux, and effects on obesity-related comorbid conditions in morbidly obese patients.
