In order to prevent gastric congestion after both of the splenic and coronary veins were taken as part of extensive portal vein resection in pylorus preserving (PP) pancreatoduodenectomy (PD), we made a splenic-inferior mesenteric venous (SpIMV) anastomosis.


Four patients underwent PP subtotal PD with such extensive portal vein resection under the diagnosis of pancreas head cancer. The portal vein was reconstructed by end-to-end anastomosis, and the coronary vein was ligated. Since the stump of the splenic vein could not be approximated to the portal or superior mesenteric vein, shunting the splenic venous flow to the inferior mesenteric vein was attempted by making a SpIMV anastomosis in 3 patients and by preserving the SpIMV confluence in a patient. Postoperative celiac angiography showed that venous outflow from the stomach, spleen and remnant pancreas collected into the splenic vein and passed through the SpIMV anastomosis or confluence, and finally drained into the portal vein by inferior mesenteric to superior mesenteric collateral.


No remarkable congestion of the stomach was observed.


In conclusion making a SpIMV anastomosis or preserving the SKpIMV confluence is beneficial for preventing gastric congestion following PP PD with extensive portal vein resection for cancer of the head of the pancreas.
