Mirror image transposition of abdominal and thoracic viscera is termed situs inversus. Duodenal obstruction in situs inversus is rare. A preduodenal portal vein, though not uncommon in situs inversus, rarely causes duodenal obstruction. Where obstruction by a preduodenal portal vein is diagnosed, a duodeno-duodenostomy is the recommended treatment. A duodenal diaphragm and other more common causes of duodenal obstruction should also be excluded in these patients.
腹部和胸部脏器的镜像转位称为内脏反位。内脏反位时十二指肠梗阻很少见。十二指肠前门静脉虽然在内脏反位时并不罕见，但很少引起十二指肠梗阻。如果诊断为十二指肠前门静脉引起的梗阻，推荐的治疗方法是十二指肠-十二指肠吻合术。这些患者还应排除十二指肠隔膜和其他更常见的十二指肠梗阻原因。
