Abstract

BACKGROUND: When pancreatic neoplasms occlude or encase the superior mesenteric-portal-splenic vein confluence with abutment of the posterior lateral wall of the superior mesenteric artery, a mesocaval shunt with or without a distal splenorenal shunt allows for safe dissection of the porta hepatis and separation of the pancreatic tumor from the superior mesenteric artery. Herein we report long-term results of the largest known series of portosystemic shunts performed at the time of pancreatectomy.

METHODS: All patients who underwent pancreatic resection with a mesocaval shunt or distal splenorenal shunt were identified from our prospective database. Demographics, perioperative treatment, and outcomes were reviewed.

RESULTS: A total of 34 patients underwent mesocaval shunt or distal splenorenal shunt, including 25 at the time of pancreatoduodenectomy, 6 during total pancreatectomy, and 3 after prior pancreatectomy. There were 15 mesocaval shunts, 16 distal splenorenal shunts, 2 combined mesocaval/distal splenorenal shunts, and 1 distal splenoadrenal vein shunt. The mesocaval group included 11 temporary and 6 permanent (3 delayed) shunts. Median operative time was 9 hours (range 6.5-13), median estimated blood loss was 950 mL (range 200-5,000), and median duration of hospital stay was 11 days (range 7-35). Four patients experienced complications that required intervention (Clavien-Dindo grade ≥III), but there were no 90-day mortalities. For patients with adenocarcinoma, median overall survival was 31 months at a median follow-up of 19 months. All but 1 shunt (distal splenorenal) were patent at last follow-up.

CONCLUSION: Mesenteric venous shunting facilitates a safe and complete tumor resection in patients who require a complex pancreatectomy, many of whom would otherwise be deemed inoperable.
