Interruption of hepatic arterial blood flow after resection of pancreaticobiliary carcinoma.

Le résumé fourni par la source

BACKGROUND/AIMS: We reviewed 17 cases of patients with interrupted hepatic arterial blood flow to determine the effect of such an interruption. MATERIALS AND METHODS: In 17 patients undergoing radical resection of pancreaticobiliary carcinoma with simultaneous hepatic artery excision (n=15) or intraoperative hepatic artery obstruction (n=2), morbidity and mortality were reviewed. Nine hepatic artery anastomoses were performed in 7 of these patients, and postoperative patency was obtained for 5 anastomoses. The patients were classified into the following groups: group I was 6 patients with complete interruption of hepatic arterial flow to the whole liver or the remnant liver, group II was 6 patients with interruption of hepatic arterial flow to a lobe of the liver, and group III was 5 patients with preservation of hepatic arterial flow. RESULTS: Disruption of the bilioenteric anastomosis occurred in all 6 patients from group I versus none of those in groups II and III (p<0.05). Liver abscess and liver failure developed in 1 patient each from group I, but the mortality rate in this group was not high. CONCLUSIONS: Hepatic artery reconstruction in patients with complete interruption of hepatic arterial blood flow appears to be necessary to avoid ischemic breakdown of the bilioenteric anastomosis.
