Abstract

To achieve complete resection of pancreatic cancer, portal vein resection has been performed with increasing frequency at the time of pancreaticoduodenal resection (pancreaticoduodenectomy or total pancreatectomy). In the meantime, visceral congestion and liver ischemia are of great concern during the procedure. We investigated safety of portal vein resection using a centrifugal pump-assisted bypass between the superior mesenteric vein and the umbilical vein. A retrospective comparison was performed in 49 consecutive patients who underwent pancreatoduodenal resection with or without portal vein resection using the bypass for pancreatic cancer. Twenty-two patients underwent portal vein resection using the bypass (group 1). The other 27 patients undergoing pancreatoduodenal resection without portal vein resection comprise the control group (group 2). Total operative time was 756 +/- 159 min and 526 +/- 109 min (p<0.001) and median blood loss was 2090 mL and 1200 mL in groups 1 and 2, respectively. However, the centrifugal pump-assisted bypass allowed stable bypass flow, and neither intestinal edema nor ischemic change of the liver was observed during portal vein resection and the subsequent reconstruction. Postoperatively, the pe...Continue Reading
