Portomesenteric Reconstruction during Whipple Procedure Using Autologous Left Renal Vein Patch Graft in a Patient with a Gastric Cancer Recurrence.

The case of vascular reconstruction of the superior mesenteric and portal vein confluence using a left renal vein (LRV) graft has been researched in this paper. The patient was a 66-year-old female who presented with features of biliary obstruction. A contrast-enhanced computed tomography scan revealed bile duct dilatation and a common bile duct tumor mass. Four years ago, she underwent stomach resection with subsequent Billroth II gastrojejunostomy due to gastric cancer. After surgical resection, on histopathological and immunohistochemistry examination, a recurrence of previously resected poorly cohesive gastric cancer was found.
