Abstract
Pancreatectomy with arterial resection for locally advanced pancreatic duct adenocarcinoma (PDA) is associated with high morbidity and is thus considered as a contraindication. The aim of our study was to report our experience of pancreatectomy with planned arterial resection for locally advanced PDA based on specific selection criteria. MATERIAL AND METHODS: All patients receiving pancreatectomy for PDA between October 2008 and July 2014 were reviewed. The patients were classified into group 1, pancreatectomy without vascular resection (66 patients); group 2, pancreatectomy with isolated venous resection (31 patients), and group 3, pancreatectomy with arterial resection for locally advanced PDA (14 patients). The primary selection criteria for arterial resection was the possibility of achieving a complete resection based on the extent of axial encasement, the absence of tumor invasion at the origin of celiac trunk (CT) and superior mesenteric artery (SMA), and a free distal arterial segment allowing reconstruction. Patient outcomes and survival were analyzed. RESULTS: Six SMA, two CT, four common hepatic artery, and two replaced right hepatic artery resections were undertaken. The preferred arterial reconstruction was splenic artery transposition. Group 3 had a higher preoperative weight loss, a longer operative time, and a higher incidence of intraoperative blood transfusion. Ninety-day mortality occurred in three patients in groups 1 and 2. There were no statistically significant differences in the incidence, grade, and type of complications in the three groups. Postoperative pancreatic fistula and postpancreatectomy hemorrhage were also comparable. In group 3, none had arterial wall invasion and nine patients had recurrence (seven metastatic and two loco-regional). Survival and disease-free survival were comparable between groups. CONCLUSION: Planned arterial resection for PDA can be performed safely with a good outcome in highly selected patients. Key elements for defining the resectability is based on the extent of the axial arterial encasement with two criteria: the origin of the CT and SMA are free from tumor invasion and the possibility of distal reconstruction.
