Bariatric surgery is an effective treatment for obesity and obesity-related complications. Weight regain after surgery plagues all methods of bariatric procedures including the minigastric bypass. The use of a ‘silastic ring’ around the gastric pouch has been shown to reduce weight regain. We present here a very rare complication of silastic ring use, in which a loop of small bowel had herniated through the ring and produced a closed loop small bowel obstruction. The patient was successfully treated with an emergency laparotomy to resect the silastic ring and release the herniated bowel. This case highlights the hernia risk that silastic rings pose and cautions careful consideration before their use.
