Intussusception of the defunctionalized intestinal segment following jejuno-ileal bypass for obesity has rarely been reported. Persistent crampy abdominal pain (often accompanied by nausea and vomiting) and normal radiologic evaluation are suggestive of this entity. The routine use of silver clips, although helpful in some instances, cannot exclude this diagnosis. A high index of suspicion and the use of sonography may prove that intussusception of the defunctionalized segment is more common than has been previously reported.
空肠回肠旁路术治疗肥胖后失功能肠段套叠鲜有报道。持续性痉挛性腹痛（常伴有恶心和呕吐）且放射学检查正常提示为此病。常规使用银夹，虽在某些情况下有帮助，但不能排除该诊断。高度怀疑并结合超声检查可能证实失功能肠段套叠比之前报道的更为常见。
