“Mini” Gastric Bypass: Systematic Review of a Controversial Procedure

Abstract

Mini gastric bypass is being explored by many bariatric surgeons as a standalone bariatric procedure. Several surgeons from different parts of the world have now published their extensive experience with this procedure. It appears to be an effective bariatric procedure with acceptable weight loss, co-morbidity resolution, and complication rates in the short and medium term. Its proponents claim that it is safer and easier than the gold standard Roux-en-Y gastric bypass. However, concerns with regard to symptomatic gastric or oesophageal biliary reflux requiring revisional surgery and long-term risk of gastric and oesophageal cancers persist. This paper reviews the published experience to date with this procedure and examines the surrounding controversy.
