Jejunoileal bypass carries a number of potential complications, one of which is intussusception of the excluded segment. The incidence of this complication is probably about one to two per cent. The usual symptoms consist of intermittent episodes of colicky abdominal pain. The roentgenographic diagnosis is difficult because the condition occurs at the blind end of the excluded segment and it is not possible to reflux contrast material to this area. If the intussusception is associated with severe gastrointestinal hemorrhage, selective angiography may provide the diagnosis.
空肠回肠旁路术有许多潜在并发症，其中之一是旷置肠段的肠套叠。这种并发症的发生率可能约为1%至2%。常见症状包括间歇性绞痛。X线诊断困难，因为这种情况发生在旷置肠段的盲端，无法将造影剂反流至该区域。如果肠套叠伴有严重胃肠道出血，选择性血管造影可能有助于诊断。
