The causes of postgastrectomy syndrome are multiple and differ in their relative frequency. Among the more unusual is intussusception of the small bowel into the stomach or into the jejunojejunostomy. We describe a patient with acute retrograde intussusception of the efferent loop into the jejunojejunostomy occurring 14 months after partial gastrectomy with Billroth II anastomosis. Several theories regarding etiology are mentioned, among them functional causes, mechanical causes and derangements in stomal function. In our case, the circulatory derangement might possibly be a causal factor. The diagnostic problems are discussed, and the importance of early diagnosis is pointed out. A chronic form of intussusception is mentioned by several authors. Often the differential diagnosis is difficult, but epigastric pain, vomiting--ultimately of blood--and a palpable mass, constitute a classic triad. X-ray and endoscopy are supplementary aids to the diagnosis. Several types of operative treatment have been used, but no operative procedure seems to be fully effective as a safeguard against recurrence.
胃切除术后综合征的病因多种多样，其相对发生率也各不相同。其中较为罕见的是小肠套叠入胃或空肠空肠吻合口。我们描述了一名患者，在毕Ⅱ式吻合术的部分胃切除术后14个月，发生了输出袢急性逆行套叠入空肠空肠吻合口的情况。文中提到了几种关于病因的理论，包括功能原因、机械原因和吻合口功能紊乱。在我们的病例中，循环紊乱可能是一个致病因素。讨论了诊断问题，并指出了早期诊断的重要性。几位作者提到了慢性套叠形式。通常鉴别诊断很困难，但上腹部疼痛、呕吐（最终呕血）和可触及肿块构成了典型的三联征。X线和内镜检查是诊断的辅助手段。已经采用了几种手术治疗方式，但似乎没有一种手术方法能完全有效地防止复发。
