ABSTRACT
Objective To summarize the clinical experience in 58 cases of split liver transplantation (SLT).Methods A retrospective analysis was conducted on 58 cases of SLT during June 2006 to January 2011.There were 13 cases performed at the first phase (2006.6-2008.12),and 45 cases at the second phase (2009.1 2011.1). The survival rate of patients,recovery of liver function,re-transplantation rate,incidence of vascular complications and biliary complications were observed,and the causes of death were analyzed.Results The median follow-up time of all the patients was 11.4 months (0-48 months).The 1- and 2-year cumulative survival rate was 77.4％ and 68.3％ respectively,re-transplantation rate was 6.9％,the incidence of vessel complications was 13.8％,and biliary complication rate was 32.1％.Fifteen cases died,including 8 deaths which were related to surgical complications.Conclusion With the donor split technology improvements and refinements in partial liver transplantation, the survival rate of SLT recipients is significantly increased,but selection of recipients is still the key factor that impacts survival rate of recipients receiving SLT.SLT can expand the resource of liver donors,and adequate selection of recipients can obtain better results.
ABSTRACT
ObjectiveTo determine the incidence,risk factors and measures to prevent biliary complications after ex vivo split liver transplantation (SLT).Method33 ex vivo SLT were performed between June 2006 and September 2010.One patient was excluded from this analysis because of early postoperative death.There were 18 males and 14 females,with a mean age of 33.4 yr (range,6 mo to 65 yr).Biliary reconstruction was carried out by duct-to-duct anastomosis in 20 and Roux-en-Y hepaticojejunostomy in 12 patients.Biliary complication was defined as either bile leak or bile duct stricture which required surgery,interventional radiology or endoscopic treatment.These biliary complications were confirmed by percutaneous tranahepatic cholangiography,endoscopic retrograde cholangiopancreatography,or T-tube cholangiography.ResultThe median follow-up was 13.5 months (3 to 54 mo).Twelve (37.5 ％ ) biliary complications occurred in 11 patients:hepatic parenchymal leak from the transeeted liver surface in 9.3％ (3/32),anastomotic leaks in 12.5％ (4/32),anastomotic strictures in 3.1％ (1/32),stump leaks from the left bile duct in 3.1 ％ (1/32),and ischemic biliary strictures in 9.3％ (3/32).Two patients died of abdominal sepsis in the 8 patients who had biliary leaks.Univariate analysis showed that graft type and biliary reconstruction were not significant risk factors for biliary leaks.ConclusionCompared with whole liver transplantation and living donor liver transplantation,biliary complications of SLT are more common.Prevention and treatment of biliary complications are important factors to improve the result of SLT.
ABSTRACT
Hepatocellular carcinoma [HCC] is one of the most common malignancies worldwide. Annually, about 200,000 patients died of HCC in China. Liver transplantation [LT] holds great theoretical appeal in treating HCC. However, the high recurrence rate after transplantation is the most important limiting factor for long-term survival. To assess the value of alpha-fetoprotein [AFP] messenger RNA [mRNA], Glypican-3 [GPC3] mRNA-expressing cells in the peripheral blood [PB] for prediction of HCC recurrence following orthotopic liver transplantation [OLT]. 29 patients with HCC who underwent OLT with a minimum clinical follow-up of 12 months were included in this retrospective study. We detected APF mRNA, follow-up of 12 months were included in this retrospective study. We detected AFP mRNA, GPC3 mRNA-expressing cells in the PB by TaqMan real-time reverse transcriptase-polymerase chain reaction [RT-PCR], pre-, intra- and post-operatively. The early recurrence of patients was evaluated. 8 [285], 15 [52%], and 9 [31%] patients had AFP mRNA detected pre-, intra-, and post-operatively, respectively. With 12 months of follow-up, HCC recurred in 7 [24%] patients. Univariate analysis revealed that positive pre- and post-operative AFP mRNA, TNM stage as well as vascular invasion were significant predictors for the HCC recurrence. Multivariate analysis revealed that being positive for AFP mRNA pre-operatively remained a significant risk factor for HCC recurrence after OLT. GPC3 mRNA was expressed in all PB samples. There was no significant difference in the expression levels of GPC3 mRNA between the HCC and control groups. There were no significant differences in GPC3 mRNA expression values between those patients with and without tumor recurrence. The pre-operative detection of circulating AFP mRNA-expressing cells could be a useful predictor for HCC recurrence following OLT. GPC3 mRNA - expressing cells in PB seem to have no diagnostic value

Objective To determine the clinical value of MRCP for peroperative evaluation of donor biliary system in living donor liver transplantation (LDLT). Methods A total of 60 living donors for the LDLT were enrolled in this study. Of the 60 donors with a mean age of 32.2 (19-60), 50were male and 10 female. MRCP was performed before and cholangiography was done during the right lobectomy in these donors. The results of MRCP were compared with those of cholangiography to determine the value of MRCP for typing the biliary system in the donors. Results The preoperative MRCP showed that 40 donors were of type Ⅰ biliary tract, 12 of type Ⅱ , 5 of type Ⅲ and 3 of other types. The intraoperative cholangiography showed that the accordance rate of MRCP was 97.4%,91% and 89% for type Ⅰ , type Ⅱ and other types, respectively. The overall rate of accuracy of MRCP was 95% (57/60). Conlusion MRCP can show types of biliary tract in living donors for liver transplantation to provide evidence for plan of surgery.
ABSTRACT
Objective To summarize the experience of reconstruction of Ⅴ and Ⅷ hepatic veins in right lobe (without middle hepatic vein) living donor liver transplantation. Methods The clinical data of 55 cases of living donor liver transplantation of right lobe without middle hepatic vein were analyzed, and Ⅴ and Ⅷ hepatic veins were reconstructed. All donors underwent evaluation on the basis of vascular anatomy, GRWR and graft volume/ESLV. Fifty-one grafts underwent reconstruction of Ⅴ and Ⅷ hepatic veins with cold-storage cadaveric iliac veins. Great saphenous vein, varicose umbilical veins, recipient intrahepatic portal veins and recipient intrahepatic veins were used respectively in the remaining 4 cases. Results One recipient died of obstruction of out-flow on the postoperative day 43. One recipient was converted to cadaver donor liver transplantation at the 7th day after operation, because of acute liver function failure. The remaining 53 cases recovered successfully. Conclusion Reconstruction of Ⅴ and Ⅷ hepatic veins with proper materials in right lobe (without middle hepatic vein) living donor liver transplantation is feasible, and the effect is satisfactory.
