Objective: To evaluate the perioperative clinical outcome and predictive factors for perioperative complication morbidity and mortality., Methods: From August 2003 to August 2008, the data of 338 cases of hepatectomy performed in the liver transplant center of the First Affiliated Hospital of Nanjing Medical University was collected in a prospective manner. The patients' perioperative clinical risk factors and results were analyzed., Results: In the 338 hepatectomy cases, 255 patients (75.4%) underwent precise anatomical hepatectomy. The overall perioperative complication morbidity was 18.1%, while the perioperative mortality was 0.6%. In a total of 211 (62.4%) cases, the operation was carried out without blood transfusion. Univariate analysis revealed that cirrhotic liver, thrombocytopenia, blood loss in operation > 1000 ml, blood transfusion in operation and several other factors were closely related with the incidence rate of complication. Multivariate logistic regression analysis indicated that thrombocytopenia and perioperative blood transfusion were important independently predictive factors for the occurrence of perioperative complications in hepatectomy., Conclusions: Precise hepatectomy enables patients to obtain better clinical outcome with low complication morbidity and perioperative mortality. Reducing hemorrhage is an important factor that lead to good clinical results.

Objective: To evaluate the outcome of emergency adult right lobe living donor liver transplantation for fulminant hepatitis., Methods: Nine cases of adult right lobe living donor liver transplantation were performed from September 2002 to August 2005, the clinical and follow-up data was analyzed., Results: According to Child Pugh Turcotte (CPT) classification, 9 patients were classified as grade C before transplant. The Model for End-Stage Liver Disease (MELD) scores of these patients were 26.7 +/- 8.8. The principal pre-transplant complications included hepatic encephalopathy (5 cases), electrolyte disturbance (3 cases), renal failure (2 cases), gastrointestinal bleeding (1 case). The operations in donors and recipients were all successful. The post-transplant complications induced pulmonary infection in 2 patients, acute renal failure in 3 and transplantation related encephalopathy in 1. There were no primary graft non-function and no blood vessel and bile tract complications occurred. One-year survival rate was 55.6%. No serious complication or death found in donors., Conclusions: Emergency adult to adult living donor liver transplantation is an effective treatment for fulminant hepatitis but the safety of the donors should be assessed strictly preoperation.

Objective: To summarize the clinical experience and some principal surgical techniques of adult to adult living donor liver transplantation (ALDLT)., Methods: The clinical data of 9 patients receiving ALDLT from September 2000 to September 2004 in liver transplantation center in the First Affiliated Hospital of Nanjing Medical University were analyzed retrospectively. The left lobe (segments II, III, IV, including the middle hepatic veins) was transplanted in 3 patients, and the right lobe (segments V, VI, VII, VIII, not including the middle hepatic veins) was transplanted in 6 patients., Results: There was no operative death in donors. The median operative time was (6.2+/-1.4) hours. The blood loss ranged from 300 to 1,200 ml. Postoperative complications included biliary fistula (1 donor) and wound fat liquefaction (1 donor). They were followed up for 6-12 months, and no long term complications were found. In recipients, the operating time ranged from 5 to 11 hours. The blood loss ranged from 800 to 7,000 ml. Modified outflow reconstruction method, microvascular reconstruction of the hepatic artery and duct to duct biliary reconstruction were performed in recipients. The median cold ischemic time of the grafts was (1.9+/-0.5) hours. The mean non hepatic stage of recipients was (98+/-26) minutes. Graft/recipient weight ratio (GRWR) was (1.20+/-0.26)%. One recipient presented postoperative complication of biliary fistula. One recipient died of serious infection 1 month postoperatively. The other 8 recipients enjoyed longterm survival., Conclusion: The procedure of ALDLT is an effective method in the treatment of decompensated end stage liver disease, and it is relatively safe for the donor. Reconstruction of vessels is the key surgical technique in the operative procedure.

Objective: To summarize our clinical experience in adult-to-adult living donor liver transplantation (ALDLT)., Methods: Clinical data of 12 patients with ALDLT performed in our center from September 2000 to June 2005 were analyzed, retrospectively., Results: Left lobe (segments II, III, IV, including the middle hepatic veins) transplantation was performed in 3 patients and right lobe (segments V, VI, VII, VIII, with or without the middle hepatic veins) transplantation was performed in 9 patients. Donors: There were no operative deaths. The median operative time was 6.20+/-1.40 hours and their blood loss ranged from 300 ml to 1200 ml. Postoperative complications included biliary fistula (1 donor) and wound fat liquefaction (1 donor). During a 6-12 months follow-up, no long-term complications were found. Recipients: The operating time ranged from 5 to 11 hours and their blood loss ranged from 800 to 7000 ml. Modified outflow reconstruction, microvascular reconstruction of the hepatic artery and duct-to-duct biliary reconstruction were done during the recipient operations. The median cold ischemia time was 1.90+/-0.50 hours. The median anhepatic phase of recipients was 1.63+/-0.43 hours. Graft/recipient weight ratio (GRWR) was (1.20+/-0.26)%. One recipient presented a postoperative complication of biliary fistula and another recipient died 1 month after the operation from serious infection. The other 11 recipients had long-term survivals., Conclusion: ALDLT is an effective treatment for decompensated end-stage liver disease patients and is relatively safe for the donors.

Objectives: To explore the relationship between the expression of IL-10 and liver regeneration following reduced-size orthotopic liver transplantation in rats., Methods: Rats models with reduced-size orthotopic liver transplantation were established. The rats were divided in three groups: partial liver resection (I), orthotopic liver transplantations (II), and reduced-size orthotopic liver transplantation (III). The expression of IL-10 and regenerative response of liver in rats were evaluated by immunohistochemistry and flow cytometry on the 1st, 2nd, 4th and 7th days after the operations, respectively., Results: The liver grafts were capable of regeneration, the proliferation activity peaked on the fourth day with 26.3+/-0.9, 35.8+/-2.2, and 32.4+/-1.8 in I, II, and III groups, respectively. The expression of IL-10 was negative correlation to liver regeneration (r=-0.58, P<0.01)., Conclusions: Whole and reduced-size transplanted livers show the same regenerative activity. The maximal regenerative response delayes slightly, compared with that after partial hepatectomy. IL-10 plays an important immunomodulatory role in liver regeneration,and the effect is affected by general immune system and other cytokines.
