[A comparison of efficacies between transjugular intrahepatic portosystemic shunt versus portoazygos devascularization in the treatment of portal hypertension with variceal bleeding].

ABSTRACT

OBJECTIVE: To compare the efficacies between transjugular intrahepatic portosystemic shunt (TIPS) and portoazygos devascularization (PAD) in the treatment of portal hypertension with variceal bleeding. METHODS: From December 1993 to December 2010, 309 patients with portal hypertension and variceal bleeding were admitted. According to their general conditions and Child-Pugh grades, they were assigned to undergo TIPS (group A, n = 235) or PAD (group B, n = 74). Before operation, compared with the PAD group, the TIPS group possessed worse liver functions, more severe ascites and a greater frequency of bleeding. After operation, the therapeutic efficacies and changes of portal hemodynamics, recurrent variceal bleeding, post-operative encephalopathy and long-term survival were evaluated between two groups. RESULTS: The postoperative portal pressure in the TIPS group ((42.6 ± 7.0) vs (26.3 ± 4.1) cm H2O) decreased much more than that in the PAD group ((38.7 ± 5.2) vs (33.5 ± 5.8) cm H2O, P < 0.01). The rebleeding rates during early postoperation were 0.85% (2/235) and 6.76% (5/74) in TIPS and PAD groups respectively, the occurring rates of hepatic encephalopathy 4.68% (11/235) and 4.05% (3/74) and the rates of operative mortality 1.70% (4/235) and 6.76% (5/74) respectively. Survival rates of 1, 3, 5 and 10 years were 98.30% (231/235) vs 92.24% (69/74), 92.41% (146/158) vs 88.06% (59/67), 80.77% (84/104) vs 79.25% (42/53), 51.43% (36/79) vs 51.85% (14/27) in TIPS and PAD groups respectively. CONCLUSIONS: As compared with PAD, TIPS offers the such advantages as less trauma, wider indication, faster hemostasis and satisfactory therapeutic efficacies. Especially for the emergency treatment of a patient with massive variceal bleeding and Child-Pugh C grade liver function, TIPS is a better option than PAD.
