Objective:To investigate the risk factors for short-term mortality and long-term survival after liver transplantation in patients with hepatitis B related acute-on-chronic liver failure.Methods:Forty patients with hepatitis B related acute-on-chronic liver failure performing liver transplantation were prospectively collected from August 2018 to July 2021 in Beijing YouAn Hospital of Capital Medical University. The mean age was (44.5±8.79) years, there were 36 males and 4 females. The basic data, including liver and kidney function, blood routine, coagulation function, lactic acid, infection indexes as well as MELD score, MELD-Na score, CLIF-C ACLFs score, CLIF OFs score, CLIF grade within 48 hours before liver transplantation were counted. The post-LT mortality within 90 days and long-term survival were observed for these patients who were divided into survival group ( n=34) and death group ( n=6) according to the survival in 3 months after liver transplantation. The measurement data conforming to the normal distribution were expressed by mean ± standard deviation ( ± s), and the comparison was performed by t-test between groups; The skewness data were expressed by M ( Q1, Q3), and the rank sum test was used for inter-group comparison. The counting data were tested by Chi square test or Fisher exact probability method. The risk factors of short-term mortality and long-term survival were analyzed through univariate and multivariate analysis as well as survival analysis. The sensitivity, specificity and cut off value were calculated by ROC curve. The patients were divided into ≥ 48.5 scores group ( n=10) and < 48.5 scores group ( n=30) by CLIF-C ACLFs score 48.5 as cut-off value. Kaplan Meier was used for survival analysis and comparison. Results:The total bilirubin (TBIL), creatinine (CR), platelet count, international normalized ratio (INR), lactic acid and neutrophil/lymphocyte ratio (NLR) within 48 hours before liver transplantation were 24.30 (13.45, 33.95) mg/dL, 0.68 (0.53, 1.11) mg/dL and 56 (39, 82)×10 9/L, 3.12(2.33, 4.46), 2.14(1.59, 4.14) mmol/L, 4.06(2.12, 9.13) for all forty patients, respectively. The mean MELD, MELD Na, CLIF OFs, CLIF-C ACLFs and AARC scores within 48 hours before transplantation were (32.1±6.3), (33.2±5.3), (11.2±2.6), (43.8±8.8) and (10.6±2.4) scores, respectively. 65% of patients were complicated with hepatic encephalopathy, 17 patients with controllable systemic infection, 10 patients with renal function injury, 2 patients with variceal bleeding and 6 patients underwent ventilator-assisted ventilation (endotracheal intubation). All 40 patients underwent emergency orthotopic liver transplantation. The incidence of postoperative complications was 47.5%, the most common was post-LT infection (27.5%), followed by renal insufficiency (17.5%). There were significant differences in neutrophil lymphocyte ratio (NLR), lactic acid, MELD score, MELD Na score, CLIF-C ACLFs score, CLIF OFs score, CLIF grades, hepatic encephalopathy, infection and renal injury between survival group and death group ( P<0.05). Univariate logistic regression analysis showed that NLR, MELD Na score, CLIF-C ACLFs score and CLIF OFs score were the risk factors for short-term mortality after liver transplantation ( P<0.05). Multivariate logistic regression analysis showed that CLIF-C ACLFs score was an independent risk factor for 3-month mortality after liver transplantation. ROC curve showed that the area under the curve of CLIF-C ACLFs score was 0.895 (95% CI: 0.779-1.000, P=0.002), and the diagnostic sensitivity and specificity were the highest, 83.3% and 85.3% respectively when cut off value was 48.5. Meanwhile, there was significant difference in long-term survival between the patients with CLIF-C ACLFs score ≥ 48.5 and < 48.5 ( P=0.001). Conclusions:NLR, MELD Na score, CLIF-C ACLFs score and CLIF OFs score within 48 hours before liver transplantation are the risk factors for short-term mortality after liver transplantation, however CLIF-C ACLFs score is an independent risk factor for three-months mortality and long-term survival in patients with hepatitis B related acute-on-chronic liver failure after liver transplantation.

Objective:To investigate the safety and efficacy of combining programmed death-1 (PD-1) with tyrosine kinase inhibitors (TKIs) in patients with advanced hepatocellular carcinoma (HCC) before liver transplantation(LT).Methods:The data of six males with a mean ± s. d. age of (57.5±4.3) years who were treated with PD-1 inhibitors combined with TKIs for advanced HCC before LT at Beijing You'an Hospital, Capital Medical University and the First Medical Center of Chinese PLA General Hospital were retrospectively analysed. The tumor stagings, the use of PD-1 inhibitors and TKIs with their discontinuation in pre-LT/post-LT liver function recovery durations, incidences of complication. The tumor recurrence and disease-free survival rates were determined on follow-up of these patients at outpatients clinics.Results:For the 6 patients included in this study, four patients were classified by the Barcelona Clinic Liver Cancer Staging (BCLC) as C and the China Liver Cancer Staging (CNLC) as Ⅲa, and two patients were classified by the BCLC staging as B and the CNLC asⅡb. The mean cycle of PD-1 inhibitor used was 5.5 (1-20), and the mean duration of PD-1 inhibitor discontinuation was 19.5 (12-45) days pre-LT. All patients who were treated with PD-1 inhibitors combined with TKIs reached the liver transplantation standard, and all successfully underwent orthotopic liver transplantation. The liver function recovered well without any serious complications post-LT. All the patients survived without developing any acute rejection or other complications. The follow-up time ranged from 8.2 to 27.3 months, with a median of 11.9 months. No patients had died, and 2 patients developed tumor recurrence. The median (range) tumor-free survival time was 10.9 (2.9-27.3) months.Conclusion:Patients with advanced HCC could benefit from combined PD-1 inhibitors with TKIs therapy pre-LT. There were no increased incidences of acute rejection and other complications post-LT.

Objective:To investigate the application value of Laennec approach in laparoscopic anatomical right hemihepatectomy (LARH).Methods:The retrospective and descriptive study was conducted. The clinicopathological data of 2 female patients who underwent LARH via Laennec approach in the First Affiliated Hospital of Kangda College of Nanjing Medical University from May to July 2020 were collected. The two patients were 51 and 57 years old, respectively. Observation indicators: (1) surgical situations; (2) postoperative situations and follow-up. Follow-up using outpatient examination and telephone interview was conducted to detect post-operative survival and tumor recurrence of patients up to December 2020. Count data were repre-sented as absolute numbers.Results:(1) Surgical situations: 2 patients successfully underwent LARH via Laennec approach, without conversion to open surgery. The operation time was 180 minutes and 185 minutes, and the volume of intraoperative blood loss was 200 mL and 400 mL, respectively. No blood transfusion or gastrointestinal decompression was performed in either patient. (2) Postoperative situations and follow-up: 2 patients began to take liquid diet on the first day and out-of-bed activities on the postoperative second to third day. There was no postoperative bile fistula or bleeding, but different degrees of peritoneal and pleural effusion occurred to the 2 patients after operation. One case was improved after right-sided thoracentesis and chest tube drainage due to dyspnea, and the other case was cured after conservative therapy. There was no perioperative death. The duration of postoperative hospital stay of 2 patients was 13 days and 11 days, respectively. Results of pathological examination showed 1 case of hepatic hemangioma and 1 case of primary liver cancer, respectively. The Laennec capsule was observed on the hepatic vein branches of segment Ⅴ, Ⅵ, Ⅶ, Ⅷ, and the gap existed between the Laennec capsule and the hepatic vein. Two patients were followed up for 7 months and 5 months，respectively. They survived during the follow-up，without tumor recurrence.Conclusion:It is safe and feasible to perform LARH by Laennec approach.
