The prognosis of hepatic artery complications after OLT is not only related to the type, extent, and timing but also closely associated with the selection and timing of the therapeutic methods. However, there is no consensus of opinion regarding the treatment of these complications. The aim of this study was to determine optimal treatment for hepatic artery complications after OLT. Methods The clinical data of 25 patients diagnosed with hepatic artery thrombosis （HAT） and hepatic artery stenosis （HAS） between October 2003 and March 2007 were retrospectively reviewed. Treatments included liver retransplantation and interventions which contain thrombolysis, percutaneous transluminal angioplasty and stent placement. Results Among five patients with HAT, 3 were treated with thrombolysis. One recovered, one died after thrombolysis and another one died of multi-organ failure after retransplantation because of recurrent HAT. The remaining 2 patients underwent successful retransplantation and have survived after that. Among 12 patients presented with HAS within 1 month postoperatively, 2 patients underwent retransplantation due to irreversible liver failure and another 10 patients were treated with interventions. The liver function failed to improve in 3 patients and retransplantations were performed in 4 patients after stent placement because of ischemic cholangitis. Among 6 patients undergoing liver retransplantations, two died of intracranial hemorrhage and infection respectively. Eight patients presented with HAS after 1 month postoperatively, 5 patients were treated with interventional management and recovered after stent placement. Among another 3 patients presented with HAS, 2 patients’ liver function was stable and one patient received late liver retransplantation due to isch展开更多

However, some patients might lose grafts due to a variety of reasons, including bile duct complications, vascular complications, primary non-function, graft rejection and disease recurrence etc. Liver retransplantation （re-LT） was the only available means for those patients whose initial grafts had failed, but the inferior outcomes of re-LT compared to primary liver transplantation （PLT） continue to be a major concern. This study aimed to analyze the indications for re-LT, optimal timing of re-LT, and strategies to improve the survival rate after re-LT.Methods From January 2001 to December 2006, we performed 738 liver transplants and 39 re-LT （5.3%） at our center. A retrospective analysis was performed to identify factors （indication for re-LT, preoperative score of model for end-stage liver disease （MELD）, interval to re-LT from primary liver transplantation, methods of vascular and biliary reconstruction and common causes of death） associated with survival.Results Mean follow-up period was 1.8 years （1 to 5 years）. Patients with MELD score less than 20 were better than those whose MELD score was 〉20 and MELD score〉30 （1-year survival, 80.0% versus 50.0% and 3/5）. The perioperative survival rate of patients who received re-LT at an interval of more than 30 days and less than 8 days after the initial transplantation was higher than those who received retransplantation between 8 to 30 days following the first operation （88.5% and 74.3% versus 50.0%）. The main causes of death were infection （60.0%）, multiple organ failure （20.0%）, vascular complications （10.0%） and biliary fistula （10.0%） in perioperative period. The overall patient survival rate of 1-month, 6-month and 1-year was 80.0%, 76.7% and 66.7%, respectively.Conclusions Our study suggested the favorable results after re-展开更多

Early and late graft failure gives way to two different clinical conditions that should be discussed separately. This study was designed to compare early and late re-OLT for patients with poor graft function after primary transplantation at our center and sum up our clinical experience in re-OLT. Methods The clinical data of 31 re-OLTs at our center from January 2004 to February 2007 were analyzed retrospectively, consisting of the first group with 14 cases of early re-OLT and the second group with 17 cases of late re-OLT.Results Biliary tract complications were the main indications for early re-OLT （57.1%） and late re-OLT （52.9%）. Other common indications were vascular complications in early re-OLT and recurrence of primary diseases in late re-OLT. No significant differences were found between the groups with regard to the volume of bleeding during operation, cold ischemia time, operative duration, and perioperative mortality; except for the model of end-stage liver disease （MELD） score. Outcome was fatal for 7 patients in early re-OLT and 9 patients in late re-OLT. Two deaths were due to multiple organ failure with 3 deaths due to severe sepsis-related disease in early re-OLT, and 4 deaths were due to severe sepsis-related disease with 3 deaths due to recurrence of hepatocellular carcinoma （HCC） in late re-OLT. One and 2-year actuarial survival rates after re-OLT were 55.2% and 36.9%, respectively, for patients in early re-OLT, and 65.1% and 52% respectively, for patients in late re-OLT. No significant differences were found regarding survival rates between the two groups. Conclusions Similar clinical results can be achieved in early and late re-OLT. Proper indications and optimal operation timing, adequate preoperative preparation, experienced surgical procedures, and effective perioperative anti-infection strategy contribute to the improvement of overall survival 展开更多

After liver transplantation, however, more than 10% pa- tients may lose the grafts caused by a variety of reasons. This review covers the most frequent indications for liver retransplantation as well as the results and specific problems with each indication. DATA RESOURCES: Searching MEDLINE (1997-2003) for articles on liver retransplantation. RESULTS: The most frequent indications of liver retrans- plantation are primary non-function, hepatic artery throm- bosis, graft rejection and recurrent diseases. The results af- ter liver retransplantation remain inferior to those after first transplantation. CONCLUSION: Liver retransplantation, which is the only means of prolonging survival in those patients whose initial graft has failed, makes an important contribution to overall survival.展开更多

However, retransplantation remains the only choice for patients with irreversible graft failure after primary transplantation. This article aimed to summarize our clinical experience in liver retransplantation. METHODS: From June 2002 to December 2005, a total of 185 cases of liver transplantation including 8 cases of retransplantation were performed in our hospital. The clinical data were analyzed retrospectively. RESULTS: The rate of liver retransplantation was 4.32%. Retransplantation was indicated for the following reasons: biliary complication (3 cases), chronic rejection (2), hepatic artery thrombosis (1), uncontrollable acute rejection (1) and hepatitis B recurrence (1). The mean model of end-stage liver disease (MELD) scores before primary transplantation and retransplantation were 15.6 and 23.9, respectively (P < 0.05). The MELD score reflected the severity of liver disease more precisely than the Child classification. The mean interval between the first and second transplantation was 316 days (78-725 days). The first three patients, with mean interval of 101 days, died of severe infection combined with multiple organ failure after retransplantation. The patients who underwent retransplantation more than six months after the first transplant had better outcomes. The one-year survival rate for retransplantation in our group was 62.5%. CONCLUSIONS: Liver retransplantation is the only means of saving the patient with hepatic allograft failure. Understanding of the indications for retransplantation, careful selection of operation timing, excellent surgical skills and meticulous postoperative management all contribute to the success of each case of retransplantation.展开更多

Retransplantation of the liver(Re LT) remains controversial because of inferior outcomes compared with the primary orthotopic LT(OLT).Meanwhile, if accompanied by vascular complications such as arterial and portal vein(PV) stenosis or thrombosis, it will increase difficulties of surgery. We hereby introduce our center’s experience in Re LT through a complicated case of ReLT.CASE SUMMARY We report a patient who suffered from hepatitis B-associated cirrhosis and underwent LT in December 2012. Early postoperative recovery was uneventful.Four months after LT, the patient’s bilirubin increased significantly and he was diagnosed with an ischemic-type biliary lesion caused by hepatic artery occlusion. The patient underwent percutaneous transhepatic cholangial drainage and repeatedly replaced intrahepatic biliary drainage tube regularly for 5 years.The patient developed progressive deterioration of liver function and underwent liver re-transplant in January 2019. The operation was performed in a classic OLT manner without venous bypass. Both the hepatic artery and PV were occluded and could not be used for anastomosis. The donor PV was anastomosed with the recipient’s left renal vein. The donor hepatic artery was connected to the recipient’s abdominal aorta. The bile duct reconstruction was performed in an end-to-end manner. The postoperative process was very uneventful and the patient was discharged 1 mo after retransplantation.CONCLUSION With the development of surgical techniques, portal thrombosis and arterial occlusion are no longer contraindications for ReLT.展开更多

METHODS: Using the UK National Registry, patients undergoing liver transplantation for HCV-related liver disease were identified. Data on patient and graft characteristics, as well as transplant and graft survival were collected to determine the outcome of HCV patients undergoing retransplantation and in order to identify factors associated with transplant survival. RESULTS: Between March 1994 and December 2007, 944 adult patients were transplanted for HCV-related liver disease. At the end of follow-up, 617 of these patients were alive. In total, 194 (21%) patients had first graft failure and of these, 80 underwent liver retransplantation, including 34 patients where the first graft failed due to recurrent disease. For those transplanted for HCV-related disease, the 5-year graft survival in those retransplanted for recurrent HCV was 45% [95% confidence interval (CI): 24%-64%] compared with 80% (95% CI: 62%-90%) for those retransplanted for other indications (P = 0.01, log-rank test); the 5-year transplant survival after retransplantation was 43% (95% CI: 23%-62%) and 46% (95% CI: 31%-60%), respectively (P = 0.8, log-rank test). In univariate analysis of all patients retransplanted, no factor analyzed was significantly associated with transplant survival. CONCLUSION: Outcomes for retransplantation in patients with HCV infection approach agreed criteria for minimum transplant benefit. These data support selective liver retransplantation in patients with HCV infection.展开更多

The topic of liver retransplantation is very controversial. Given the critical organ shortage, the question arises as to whether hepatic retransplantation should be offered liberally despite its greater cost, and inevitable denial of access to primary transplantation for the other patients on the waiting list. We suggest that careful selection of the retransplant candidates will improve outcomes and allow rational use of the limited organ supply. Analysis of the available literature allows us to identify the main predictors of morbidity and mortality for this patient population. It also enables development of a detailed plan for perioperative management. The role of transesophageal echocardiography (TEE) as a monitor in the complex liver transplant cases is also discussed. Our report is a significant contribution to the very limited data available on the subject of multiple liver retransplants.展开更多

It the malignancy should be decreased or the malignant cells reversed, theabove abnormal changes could be reduced or disappear. BALB/c mice bearing ascites liver cancer wereused, Chinese herbal prescription combined with copper and ferrum (CHPCCF) was given by gavage for 10days, and then some cell-biological parameters were measured; further , the ascites cancer cells (controland treatment) were removed and retransptanted to another mice and observed. The results showed that inCHPCCF treatment group, DNA content of the cancer cells was decreased, and the proliferation index wasreduced (control : 83 . 4 ± 2 . 6, CHPCCF group : 78. 8 ± 1 . 5 ; or control : 67. 2 ± 1 . 3 , CHPCCF group : 64. 2 ±l . 6, P < 0. 02) , the number of the cancer cells in Gl phase increased obviously, but, those of S + G2Mphases decreased ( P < 0. 05 ￣ 0. 01 ) ; on the DNA histogram, the diploid peak became higher and bigger,but aneuploid or multiploid peaks became smaller. Furthermore, retransplanted experiments showed that in2/10 animals, the tumors did not grow, and in other 8/10 animals , the tumors grew, but the tumors' sizewere smaller than that of the control ; the growth inhibition rate was 71 . 7% ￣ 88. 3% ; and tumors ' grewslowly ; the growth curve of the tumors in CHPCCF group was considerably lower than that of the control ; thesurvival period of retransplanted animals was prolonged significantly (from 26. 1 ± 11 . 8 to 38. 1 ± 9. 6, or to39 . 6 ± 7 . 2 days, P<0 . 01 ); the increase in life span was 46% and 52% respectively. The results suggestedthat CHPCCF could reduce the malignancy of mice liver cancer cells.展开更多

The results showed that inCHPCCF treatment group, DNA content of the cancer cells was decreased, and the proliferation index wasreduced (control : 83 . 4 ± 2 . 6, CHPCCF group : 78. 8 ± 1 . 5 ; or control : 67. 2 ± 1 . 3 , CHPCCF group : 64. 2 ±l . 6, P < 0. 02) , the number of the cancer cells in Gl phase increased obviously, but, those of S + G2Mphases decreased ( P < 0. 05 ￣ 0. 01 ) ; on the DNA histogram, the diploid peak became higher and bigger,but aneuploid or multiploid peaks became smaller. Furthermore, retransplanted experiments showed that in2/10 animals, the tumors did not grow, and in other 8/10 animals , the tumors grew, but the tumors' sizewere smaller than that of the control ; the growth inhibition rate was 71 . 7% ￣ 88. 3% ; and tumors ' grewslowly ; the growth curve of the tumors in CHPCCF group was considerably lower than that of the control ; thesurvival period of retransplanted animals was prolonged significantly (from 26. 1 ± 11 . 8 to 38. 1 ± 9. 6, or to39 . 6 ± 7 . 2 days, P<0 . 01 ); the increase in life span was 46% and 52% respectively. The results suggestedthat CHPCCF could reduce the malignancy of mice liver cancer cells.
