Four patients developed duodenal obstruction after 161 abdominal aortic reconstructions, an incidence (2.5%) rivaling that of graft infection and arterioenteric fistula. The diagnosis is easily confirmed by gastrointestinal contrast studies. Duodenal obstruction is usually caused by perigraft collagenous adhesions and is probably less likely to occur if the mobilized duodenum is not replaced directly over the aorta during resuture of the retroperitoneum. Undetected duodenal obstruction leads to rapid dehydration and electrolyte and caloric depletion.
在161例腹主动脉重建术后，有4例患者发生十二指肠梗阻，其发生率（2.5%）与移植物感染和动脉肠瘘相近。通过胃肠道造影检查很容易确诊。十二指肠梗阻通常由移植物周围的胶原粘连引起，如果在腹膜后重新缝合时，游离的十二指肠不直接放回主动脉上方，其发生的可能性可能较小。未被发现的十二指肠梗阻会导致迅速脱水以及电解质和热量消耗。
