INTRODUCTION: Portomesenteric vein resections are a well-established part of pancreatectomies for advanced tumors that invade the portomesenteric axis. There are two main types of portomesenteric resections: partial resections, where only part of the venous wall is removed and segmental resection, where the full circumference of the wall is removed. The aim of this study is to compare short-term and long-term outcomes between these two techniques. METHODS: This is a single-centre retrospective study of the patients with pancreatic cancer who underwent pancreatectomy with portomesenteric vein resections between November 2009 and May 2021. RESULTS: From a total of 773 pancreatic cancer procedures, 43 (6%) patients underwent pancreatectomy with portomesenteric resections: 17 partial and 26 segmental. The overall median survival was 11 mo. For the partial portomesenteric resections, the median survival was 29 mo, and for the segmental portomesenteric resections, it was 10 mo (P = 0.019). The primary patency of the reconstructed veins after partial resection was 100% and after segmental resection was 92% (P = 0.220). Negative resection margins were achieved in 13 patients (76%) who underwent partial portomesenteric vein resection and 23 patients (88%) who underwent segmental portomesenteric vein resection. CONCLUSIONS: |Although this study is associated with worse survival, segmental resection is often the only way to safely remove pancreatic tumors with negative resection margins.
