Multiple vascular reconstructions during pancreatectomy: Surgical techniques and strategies

Abstract

Objectives Pancreatic body and tail tumors account for one-third of all pancreatic tumors and can be diagnosed later than pancreatic head tumors because they present symptoms much later. When analyzed, most of them are generally unresectable because they are invaded into adjacent organs and vascular structures. We aimed to present our cases of vascular resection and anastomosis, where isolated tumor resection cannot be performed due to invasion of adjacent vascular structures. Methods Between January 2019 and January 2021, the files of eight patients who had one or more vascular invasions due to the pancreatic body and tail tumor and therefore underwent vascular resection in addition to pancreatectomy were accessed. Results Portal vein and hepatic artery repair were performed in all eight patients. Superior mesenteric artery anastomosis was performed in four patients, inferior vena cava repair was performed in two patients, and renal vein anastomosis was performed in two patients. Primary end-to-end repair, Dacron graft, ring-enforced polytetrafluoroethylene graft, and saphenous vein graft techniques were used during vascular interventions. Conclusions We wanted to share our experience with the resection of vascular structures and anastomosis techniques. We believe that the indications of tumor surgery can be improved and redesigned by performing more routinely vascular resections and reconstructions in the future.
