  • Title: Modified distal splenorenal shunt with expanded polytetrafluoroethylene interposition.
    Author: Nagasue N, Ogawa Y, Yukaya H, Hirose S.
    Journal: Surgery; 1985 Nov; 98(5):870-8. PubMed ID: 4060065.
    Abstract:
    Two types of modified distal splenorenal shunt with expanded polytetrafluoroethylene (Gore-Tex; WL Gore & Associates Inc., Elkton, Md.) interposition were performed in 18 consecutive patients with esophageal or esophagogastric varices. There were 12 men and six women ranging in age from 32 to 76 years. The causes of portal hypertension were cirrhosis of the liver in 15 patients, chronic hepatitis in two, and idiopathic portal hypertension in one. In five patients the left gastric vein branched off from the splenic vein; bilateral gastric venous decompression was achieved by preserving the splenic vein. Porta-azygos disconnection was routinely performed by confirming repeated intraoperative direct splenoportography. The operations were elective in seven and were emergencies in five patients. Six patients underwent a prophylactic shunt; all patients had "red color signs" endoscopically, and three of them had concomitant hepatocellular carcinoma. Postoperative morbidity was minimal and there was no mortality. Shunt patency was confirmed angiographically in all patients 14 to 56 days after surgery. The varices disappeared or significantly improved in all patients. No patients had variceal bleeding postoperatively. Hepatic encephalopathy was transiently seen in one (the oldest) patient.
