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.
减重手术是治疗肥胖和肥胖相关并发症的有效方法。手术后体重反弹困扰着所有减重手术方法，包括迷你胃旁路手术。在胃袋周围使用“硅酮环”已被证明可以减少体重反弹。我们在此介绍一种硅酮环使用的非常罕见的并发症，即小肠环疝通过硅酮环并产生闭襻性小肠梗阻。患者通过紧急剖腹手术成功治疗，切除硅酮环并释放疝出的肠管。本病例强调了硅酮环存在疝的风险，并在使用前谨慎考虑。
