Objective To investigate the impact of preoperative portal vein thrombosis (PPVT) on living donor liver transplantation (LDLT).Methods In this study,99 patients who underwent LDLT by the same surgical team of Tianjin First Centre Hospital from 2007 to 2011 were retrospectively analyzed.According to whether there was a PPVT,all the patients were divided into PPVT group (26 cases) and non-PPVT group (73 cases).The preoperative risk factors and the impact of PPVT on LDLT and outcomes were analyzed.Results Among 26 PPVT patients there were 23 cases in grade Ⅰ and 3 cases in grade Ⅱ.Splenectomy was found to be an independent risk factor for PPVT (x2 =10.211,P =0.001).PPVT prolonged the anhepatic phase (Z =-2.430,P =0.015),but the incidence of surical complications and mortality were no statistical differences between the PVT group and the non-PVT groups.Meanwhile,there was no statistical difference of 1-and 3-year survival rate between the two groups(x2 =0.505,P =0.477).Conclusions With proper intraoperative treatment and postoperative prevention,PPVT does not affect the outcomes of patients suffering from grade Ⅰ or Ⅱ PPVT.However,PPVT added to difficulties of operation,so the detailed preoperative evaluation and careful intraoperative operation is necessary.

Objective:To follow up the hepatitis B recurrence post liver transplantation using the combination of lamivu dine and high-dose intravenous/intramuscular hepatitis B immunoglobulin.Methods:Fifty-two consecutive patients who underwent liver transplantation were included in this analysis.All patients were administered lamivudine combined with hepatitis B immunoglobulin intravenous(V group)or intramuscular(M group)injection prophylaxis.Dosages of hepatitis B immunoglobulin were 4 000 U during anhepatic phase,2 000 U/d during the first six days after operation,2 000 U/week at 2-4 weeks after operation and 2 000 U/month at 2-6 months after operation.The dosages of hepatitis B immunoglobulin were decided by blood concentrations at 6 months after transplantation in both groups(HBsAb titer≥200 U/L during the 6-12 months after operation;100-200 U/L one year after operation).The negative-conversion rates of serum HBsAg,serum HBsAb levels and hepatitis B recurrence rate at the 6th month,1 year after transplantation and at the end of this study were investigated.Results:The daily average negative-conversion rate of serum HBsAg was significantly faster in V group than that of M group within the first 4 postoperative days(P ＜ 0.05).The 100% of serum HBsAg negative-conversion rate was obtained in two groups after one week of operation.No recurrence was found in two groups.And the ease of death was independent on HBV recurrent during the follow-up.Conclusion:Lamivudine combined with hepatitis B immunoglobulin intravenous/intramuscular injection prophylaxis was effective protocol for the hepatitis B recurrence after the liver transplantation.

Objective To evaluate intervention in combination with choledochoscopic in treatment of biliary obstruction after orthotopic liver transplantation.Methods A retrospective review was performed in the 36 patiants with biliary strictures and bilary cast after the liver tiamsplantalion.All the patients received changing catheters,T-tube sinus tract dilation,choledochoscopic treatment,keeping catheters drainage and supporting.Result 26 patiants got satisfactory results and 8 controlled.The left 3 patients underwent retransplantation.Conclusion Intervention in combination with choledochoscopic treatment is effective to deal with biliary obstruction after liver transplantation.

ObjectiveTo study the impact of allocation of organ arteries and their reconstruction for donor livers on arterial complications after liver transplantation from organ clusters obtained by combined liver,kidney,pancreas and duodenum harvesting.The aim is to guide future use of donor organs more safely and rationally with a decrease in postoperative complications.MethodWe studied 11 patients.ResultsThere was no hepatic artery anomaly.A Carrol artery patch was obtained at the bifurcation of the proper hepatic artery and the gastroduodenal artery in these donor livers.In one patient,an arterial graft was used because of inadequate arterial length,and arterial thrombosis developed which required re-transplantation.The hepatic arterial reconstruction was successful for the remaining 10 patients.One patient died of pulmonary infection 5 months post transplantation.ConclusionWhen combined liver,kidney,pancreas and duodenum harvesting was used,enough arterial length of the recipient must be preserved.There should be adequate and prompt communication between the teams carrying out the donor operation and the recipient operation.A Carrol arterial patch of the proper hepatic artery and the gastroduodenal artery for the donor liver,and the use of microsurgical vascular anastomosis in the operation are the keys to prevent hepatic arterial complications after liver transplantation.Multi-organ harvesting can be used for obtaining donor livers in liver transplantation.

ObjectiveTo investigate prophylaxis and treatment of bile leakage from hepatic duct anomalies after liver transplantation.MethodsWe retrospectively analyzed 3 patients with bile leakage from hepatic duct anomalies after liver transplantation in our institute.The graft procurements were combined liver-kidney harvesting.The reconstruction of the bile ducts was end-to-end anastomoses.ResultsIn the first patient with a right accessory duct joining the cystic duct,leakage of bile came from the stump of the cystic duct after anastomosis of the bile ducts.The original anastomosis was taken down,and reanastomosis was performed after plasty of the bile ducts.The patient recovered uneventfully.In the second patient with a Luschka bile duct,the biliary fistula closed spontaneously after percutaneous drainage.However,re-transplantation was performed for severe infection 7 month after the primary transplantation.In the third patient with an accessory hepatic duct from the right posterior sector joining the common bile duct,the bile duct stump which we missed leaked bile.Re-transplantation was performed because of severe complications.Conclusion Understanding the anatomy of intra- and extra-hepatic bile ducts and their common anomalies identifying the structures in the porta hepatis during preparation of the liver grafts,and looking for possible accessory hepatic ducts and aberrant bile ducts are important steps to prevent bile leakage in liver transplantation.

Objective To summarize and explore the clinical characteristics,treatment and outcome of measles in pediatric liver transplant recipients.Method A total of 56 recipients underwent pediatric liver transplantation from June 2013 to April 2014,and 4 recipients suffered from measles post-liver transplantation with the incidence being 7.1％.The data of 4 recipients were retrospectively analyzed.All of the 4 cases were subjected to liver transplantation at our center for biliary atresia and cholestasis liver cirrhosis.All the patients received the combined immunosuppressive regimen on the basis of tacrolimus.All the patients did not accept the immunization with measles vaccine because of the primary liver diseases.All the cases presented the clinical manifestations of cough,high fever (T ＞38.5℃C) and conjunctiva congestion before the rashes came out.Maculopapular rashes appeared about 4 days after the fever.The rashes first appeared from the skine post aurem,face,neck,and then spread to trunk and extremities.Koplik's spots on the buccal mucosa were observed in all the 4 cases.The serological test of IgM antibodies to measles was done.The treatment was adjusted as soon as the diagnosis of measles was clear.Immunosuppressants were decreased or stopped,intravenous immunoglobulin (IVIG) combined with anti-infection drugs was given.Result The clinical manifestation of measles in pediatric liver transplant recipients was serious.There were 3 cases complicated with pneumonia,and one case with laryngitis.Two cases presented severe measles pneumonia and developed into severe respiratory failure requiring mechanical ventilation.Three eases recovered from the therapy and 1 case died of respiratory failure.Conclusion Pediatric liver transplant recipients who suffered from measles are at high risk of severe pneumonia.Measles pneumonitis is frequently fatal in immunocompromised pediatric patients.The treatment shoule be given as soon as possible.

Objective To invastigate the effect of living donor liver transplantation(LDLT) with middle hepatic vein(MHV) and LDLT without MHV on the donor. Methods Between August 2007and August 2008, 62 LDLT were performed, 30 LDLT with MHV (group A), 32 LDLT without MHV (group B). Before operation, comprehensive assessment the graft size, remnant liver volume (RLV), fatty liver, MHV type, and the level of portal hypertension in recipient to determine whether harvested MHV. The graft was harvested depending on the port vein and hepatic artery ischemia-line,ultrasound was used to definite the branch of MHV. The donor operative time, intraoperative blood loss, postoperative hospital stay, bilirubin, INR, ALT, albumin, and complications were recorded in detail. Results Operative time, blood loss, hospital stay between group A and group B were not significant difference. But the bilirubin, INR, ALT in group A was higher than group B; Albumin recovered slower and with more ascites in group A. The early complications post-operation were similar in the two groups. There were 2 cases with wound infection in group A and 3 in group B. 3 cases complicated with cholestasis in group A and 1 case in group B, all of them gradually recovered to normal after 2 weeks. 2 cases occurred cross-section bile leakage in either group, the patients administrated with anti-infection, external drainage and recovered;4-7 days after operation, there were 6 cases in group A and 5 cases in group B occurred delayed gastric emptying, it was alleviated after adjust diet, encouraging activities and administrated with gastrointestinal motility drugs. Conclusion Right graft with the middle hepatic vein may lead donor recovery delayed, but with precise evaluation, especially MHV type, remnant liver volume (RLV%)＞30%, preserve the drainage of V4b and the artery segment Ⅳ,it's can ensure the donor's safety.

Objective To Establish an evaluation system of the quality of life for Chinese liver and kidney transplant recipients,and develop a specialized scale to measure the quality of life (QOL)for such recipients preliminarily.Methods By combining subjective and objective methods,this study determined the evaluation system and created items of QOL scale based on literature analysis,Delphi method (expert consultation),interviews,and experience of researchers.Then,a nationwide clinical survey was conducted on 5 Level Ⅲ Class A hospitals.454 valid questionnaires were collected,including 153 from liver recipients,and 301 from kidney recipients.Subjective statistical methods such as critical Ratio method,correlation coefficient method,dispersion tendency method,and exploratory factor analysis were used for selection of questionnaire items.Results The study established an evaluation system of QOL for liver and kidney transplant recipients,including 4 primary indexes and 12 secondary indexes,and developed QOL scales that were appropriate for liver and kidney transplant recipients respectively.Conclusions The structure of QOL scale for liver and kidney transplant recipients was basically consistent with theoretical assumption.The QOL scale for patients showed good reliability and validity,therefore,it can fully reflect the quality of their life.
