Multicenter StudyPostoperative morbidity and long-term survival after pancreaticoduodenectomy with superior mesenterico-portal vein resection.
The role of superior mesenteric-portal vein resection (SM-PVR) for vein invasion or tumor adherence during pancreatoduodenectomy (PD) is still under debate. We investigated morbidity, mortality, and long-term survival in patients who underwent PD with or without SM-PVR. Between July 1994 and December 2004, 222 PD (78% pylorus preserving, 19% Whipple, and 3% total pancreatectomy) were performed for malignant disease. ⋯ In multivariate analysis, the resection margin (P = 0.02, RR: 5.1, 95% CI: 1.1-2.8) and a histologically undifferentiated tumor (P = 0.05, RR: 3.8, 95% CI: 1.0-2.5) significantly influenced survival. After PD, perioperative morbidity and long-term survival in patients with SM-PVR were similar to those of patients without vein resection. In case of tumor adherence or infiltration, combined resection of the pancreatic head and the vein should always be considered in the absence of other contraindications for resection.
