Small bowel diverticulitis of the Roux loop after gastric bypass

The epidemic of obesity and the introduction of laparoscopic techniques have greatly increased the popularity of bariatric operations such as Roux-en-Y gastric bypass (RYGBP). Acquired diverticular disease of the small bowel is a rare condition that becomes symptomatic in about 10% of the cases. We report a 48-year-old morbidly obese woman who presented 2 months after laparoscopic RYGBP with a perforated diverticulum of the Roux loop. The diagnostic and therapeutic implications are discussed.
