ABSTRACT
<p><b>OBJECTIVE</b>To retrospectively analyze the surgical outcome of portal hypertension and explore the risk-factors of long-term survival after operation.</p><p><b>METHODS</b>The data of 149 patients (male 119, female 30, aged from 19 to 73 years old) with portal hypertension treated surgically from January 1996 to October 2007 was collected. Among these patients, there were 110 patients for Child A and 39 patients for Child B according to Child-Pugh classification. According to different surgical modality, all patients were divided into devascularization group (n = 85) and shunting group (n = 64).</p><p><b>RESULTS</b>The follow-up rate was 78.8% and the average follow-up time was (46.3 +/- 30.4) months. The overall survival rates of 1-, 3-, 5- and 10-years were 95.6%, 88.7%, 83.4% and 65.1% respectively. Meanwhile the survival rates of 1-, 3-, 5- and 10-years in devascularization group and in shunting group were 95.4%, 87.7%, 80.6%, 56.3% and 95.8%, 90.1%, 86.8%, 72.6% respectively. There was no significant difference in survival rate between these two groups (P > 0.05). Child-Pugh classification has been the most important risk-factor that could influence long-term survival after operation by analysis of COX regression and it showed that the long-term survival time in Child A was longer than in Child B. The re-hemorrhage rates of 1-, 3- and 5-years in shunting group would be much better than in devascularization group. The rate of postoperative encephalopathy in devascularization group and shunting group was 6.9% and 6.1% respectively and there was no significant difference (P > 0.05). The portal venous pressure and flow of portal vein decreased significantly after shunting operation (P < 0.05).</p><p><b>CONCLUSIONS</b>The mainly sole risk-factor of long-term survival for portal hypertension has been the classification of Child-Pugh, not surgical procedure. The individualized proximal splenorenal shunt is much better than devascularization in controlling variceal hemorrhage.</p>

Objective To summarize the clinical experience in liver retransplantation. Methods From June 2002 to December 2005,a total of 185 cases of liver transplantation were performed in our hospital,including 8 cases of retransplantation.Those clinical data were analyzed retrospectively. Results The rate of liver retransplantation was 4.32%.The average MELD scores before primary transplantation and retransplantation were 15.6 and 23.9,respectively.The average interval between primary transplantation and retransplantation was 316 days(78~725 days).Causes of retransplantation included 3 cases of biliary complications,2 cases of chronic rejection,1 case of hepatic artery thrombosis,1 case of acute rejection and 1 case of recurrence of hepatitis B.The former 3 cases died of severe infection combined with multiple organ failure 101,16 and 28 days after retransplantation.The latter 5 cases recovered smoothly,and have survived 27,12,8,4 and 3 months up to now. Conclusion Liver retransplantation is an effective way to save the patient with hepatic allograft failure.Good knowledge of the indications of retransplantation,careful selection of the operation time,excellent surgical skills and meticulous postoperative management will contribute to the success of liver retransplantation.
