Distal pancreatectomy for body-tail pancreatic cancer: is there a role for celiac axis resection?

摘要

BACKGROUND/AIMS: Body-tail pancreatic cancer is an aggressive disease with a low resectability rate and a poor prognosis. Celiac axis invasion usually contraindicates resection. The aim of this study was to analyze the feasibility of distal pancreatectomy (DP) with celiac axis resection (DP-CAR) for locally advanced body-tail pancreatic cancer. METHODS: All DPs performed between January 1989 and December 2007 were considered. DP and DP-CAR were reviewed for pre-, intra- and postoperative data. An extensive, detailed literature review on DP and DP-CAR was also performed. Results: DP was performed in 49 of our patients, and 745 cases were retrieved from the literature. The overall morbidity and mortality rates were 32.0 and 3.0%, respectively. We performed DP-CAR in 5 patients with no mortality but 80% morbidity. A further 90 patients were retrieved from the literature. Arterial reconstruction was needed in 1/5 of our patients and in 13/90 of patients in the literature. Collaterals from superior mesenteric artery maintained adequate hepatic artery blood flow in the remaining 81 patients. The overall morbidity and mortality rates were 40.6 and 2.1%, respectively. The median survival ranged between 4.5 and 25 months after DP and was 13 months after DP-CAR. CONCLUSIONS: DP-CAR improves resectability without increasing the mortality rate. The complication rate after DP-CAR was higher than after DP, but still within the range of extended DP. DP-CAR should be considered for the inclusion among the 'extended' procedures for the treatment of body-tail pancreatic cancers invading the celiac axis. and IAP.
