METHODS： From January 2002 to July 2006, 50 cases of A-A LDLT were performed at West China Hospital, Sichuan University, consisting of 47 cases using right lobe graft without middle hepatic vein （HHV）, and 3 cases using dual grafts （one case using two left lobe, 2 using one right lobe and one left lobe）. The most common diagnoses were hepatitis B liver cirrosis, 30 （60%） cases; and hepatocellular carcinoma, 15 （30%） cases in adult recipients. Among them, 10 cases had the model of end-stage liver disease （HELD） with a score of more than 25. Donor screening consisted of reconstruction of the hepatic blood vessels and biliary system with 3-dimension computed tomography and volumetry of whole liver and right liver volume. Various improved surgical techniques were adopted in the procedures for both donors and recipients. RESULTS： Forty-nine right lobes and 3 left lobes （2 left lobe grafts for 1 recipient, 1 left lobe graft for 1 recipient who had received right lobe graft donated by relative living donor） were obtained from 52 living donors. The 49 right lobe grafts, without HHV, weighed 400 g-850 g （media 550 g）, and the ratio of graft volume to recipient standard liver volume （GV/SLV） ranged from 31.74% to 71.68% （mean 45.35%）. All donors＇ remnant liver volume was over 35% of the whole liver volume. There was no donor mortality. With a follow- up of 2-52 mo （media 9 too）, among 50 adult recipients, complications occurred in 13 （26%） cases and 4 （8%） died postoperatively within 3 mo. Their 1-year actual survival rate was 92%.CONCLUSION： When preoperative CT volumetry shows volume of remnant liver is more than 350, the ratio of right lobe graft to recipients standard liver volume exceeding 40%, A-A LDLT using right lobe graft without MHV should be a very safe procedure for both donors and recipients, otherwise dual grafts liver transplantation should be considered.展开更多

METHODS： Between January 1995 and March 2006, 50 patients with end-stage liver disease received LDLT in our department. Donors （at the age of 27-58 years） were healthy and antibody （ABO）-compatible. The protocol of evaluation and selection of donors, choice of surgical methods and strategy applied in the safety evaluation of donors were analyzed. RESULTS： A total of 115 candidate donors were evaluated for LDLT at our center. Of these, 50 underwent successful hepatectomy for living donation. The elimination rate for donors was 43.5%. Positive hepatitis serology and ABO incompatibility were the main factors for excluding candidates. All donors recovered uneventfully. The follow-up time ranged from 3 to 135 too. The incidence of major and minor medical complications was 12.0% and 28.0%, respectively. CONCLUSION： LDLT provides an excellent approach to the problem of donor shortage in China. With a thorough and complete preoperative workup and meticulous intra-and postoperative management, LDLT can be performed with minimal donor morbidity.展开更多

METHODS: We investigated retrospectively 52 living donor liver resections performed from October 2003 to July 2006. All patients were evaluated by blood tests and abdominal CT. The mean donor age was 28.2 ± 7.4 years. Residual liver volume was 42.1% ± 4.7%. Mean operative time was 420 ± 76.2 min; mean ICU stay, less than 36 h; mean hospital stay, 16.4 ± 8.6 d; and mean follow-up period, 6 mo. RESULTS: There was no mortality. The overall complication rate was 40% (21 donors). Major complications included biliary leak in two, and pneumonia in 2 donors. Minor complications included mild pleural effusion in 12 donors, transient ascites in 6, mild depression in 4, intra-abdominal collections in 2, and wound infections in 1 donor. Residual liver volume did not affect the complication rate. None required re- operation. Return to pre-donation activity occurred within 5-8 wk. CONCLUSION: Right hemi-hepatectomy can be performed safely with minimal risk in cases of careful donor selection. Major complications occurred in only 7.7% of our series.展开更多
