Clinical Significance of Portal-Superior Mesenteric Vein Resection in Pancreatoduodenectomy for Pancreatic Head Cancer

Abstract

Aggressive surgical resection should be attempted in cases with suspected PV-SMV invasion because 21.1% of patients had no true invasion and showed better survival than those with true invasion. However, invasion into the tunica intima may be a poor prognostic factor for survival even after margin-negative PD for pancreatic adenocarcinoma.
