Gastric Cancer in One-Anastomosis Mini-gastric Bypass: Case Report and Systematic Review.

In the last years, one-anastomosis gastric bypass (OAGB) has been proposed more frequently as obesity surgery technique. Several trials have demonstrated that the easier technical feasibility does not affect the long-term surgical result. However, concern about increased risk of gastric and esophageal cancers has been expressed by several bariatric surgeons. The present study reports the 2nd case of cancer of the gastrointestinal-jejunal anastomosis in a OAGB patient focusing the attention on some technical issues correlated and offering a systematic review of the literature.
