We report an unusual case of a prepancreatic postduodenal portal vein (PPPV), incidentally discovered during total gastrectomy. If it had not been noticed, this portal vein might have been ligated and divided with disastrous consequences. This anomaly was not diagnosed preoperatively, but it could have been. Although embryological anomalies of the portal venous system, such as PPPV and preduodenal portal vein, are rarely encountered in abdominal surgery, surgeons must be aware of their possibility and be able to recognize them to avoid major intraoperative injury.
我们报告了一例在全胃切除术中偶然发现的胰前十二指肠后门静脉（PPPV）异常病例。如果未被发现，这条门静脉可能会被结扎切断，从而导致灾难性后果。这种异常术前未被诊断出来，但其实是可以诊断出来的。虽然门静脉系统的胚胎学异常，如PPPV和十二指肠前门静脉，在腹部手术中很少见，但外科医生必须意识到其可能性，并能够识别它们，以避免术中发生重大损伤。
