Objective:To evaluate the effects of pegylated interferon (Peg-IFN) alfa-2b combined with nucleotide analogues (NAs) on the recurrence of hepatitis B-related liver cancer after resection, and to explore the changes of HBsAg and HBV DNA in patients with chronic hepatitis B liver cancer during postoperative treatment.Methods:The prospective study was conducted. Clinical data of 43 patients with hepatitis B-related liver cancer who underwent radical resection treated in 900th Hospital of People′s Liberation Army were prospectively analyzed from January 2020 to December 2021. Among 43 patients, there were 39 males and 4 females, the age was 30-76 years. According to different treatment methods they were divided into two groups, the patients treated by Peg-IFN alfa-2b combined with NAs were devided into the IFN group( n=10), and those treated by NAs alone into the NAs group( n=33). Two-pair semi-quantitative were collected every 3 months after operation. The recurrence-free survival rate, recurrence time after 2 years in the two groups, the clearance rate and the negative rate of HBsAg and HBV DNA in the two groups. Peg-IFN alfa-2b was evaluated in improving the prognosis of hepatitis B-related liver cancer. The measurement data of normal distribution were expressed by mean±standard deviation ( ± s), and t-test was used for comparison between the two groups. Chi-square test was used for comparison between the two groups of count data. Repeated analysis of measurement variance was used for analysis HBsAg and HBV DNA changes of the interferon group overall survival time and recurrence-free surrival time of patients was estimated using Kaplan-Meier method and the difference between groups was assessed using Log-rank test. Results:HBsAg and HBV DNA: The HBsAg clearance rate at 24 weeks and that at 48 weeks in the IFN group were 24.6% and 59.0% respectively. The HBsAg negative rate at 48 weeks was 16.7%. The HBV DNA clearance rate at 24 weeks and that at 48 weeks were 33.9% and 53.8% respectively. The HBV DNA negative rate was 0 at 48 weeks. The levels of HBsAg and HBV DNA in the IFN group decreased gradually with time. There were statistically differences between the levels of HBsAg and HBV DNA at 0 weeks, 24 weeks and 48 weeks( P<0.05). The 2-year overall survival rates of IFN group and NAs group were 100% and 90.9% respectively. The 2-year recurrence-free survival rates were 90.0% and 63.6% respectively. There were no significant statistical differences in the overall survival rate and recurrence-free survival rate between the groups ( P>0.05). The postoperative recurrence time of the IFN group and the NAs group were (15.00±7.07) months and (5.78±3.39) months respectively. The difference between the two groups was statistically significant ( t=3.160, P<0.01). Conclusion:Long-term antiviral therapy of Peg-IFN alfa-2b combined with NAs can prolong the recurrence time of liver cancer, reduce the levels of HBsAg and HBV DNA in serum, and potentially improve the survival rate of the patients compared with therapy of NAs alone.

Objective:To investigate the effect of different spray-coagulation time of argon plasma coagulation (APC) injury on the Glisson system primary branche(G1) in the hepatic portal of pigs.Methods:Fifty clean healthy domestic pigs (27 females and 23 males, aged 7 to 14 months) were selected, with the body weighted (100.0±9.5) kg. They were randomly divided into five groups (A, B, C, D, and E), with 10 pigs in each group. G1 models were made and sprayed by APC for 1, 2, 3, 4, and 5 seconds. The damage, maximum damage area, maximum damage depth, and damage of the three branches of the Glisson system (the first branches of the portal vein, intrahepatic bile duct, and hepatic artery) were compared among the groups. The pigs were divided into two groups based on whether the three branches were damaged or not: the three-branch damage group ( n=23) and the control group ( n=27). The maximum damage area and maximum damage depth were compared between the two groups. Results:After the APC spraying, circular or elliptical damage appeared on the surface of the G1, with changes such as yellow-brown color, brown color, charred appearance, and defects. Under the microscope, G1 capsule was found to be deficient, the fibrous tissue beneath the capsule was ruptured, and the structures of small blood vessels and small bile ducts were incomplete. " Burn marks" and damage to the three branches of the Glisson system in G1 were also observed, and the damage was more severe at the center of the spray-coagulation. As the spray-coagulation time increased, the maximum damage area of the G1 model also increased, and the two were positively correlated ( r=0.90, P<0.001). The maximum damage depth was also positively correlated with spray-coagulation time ( r=0.97, P<0.001). The numbers of pigs with damage to the three branches of the Glisson system in Groups A-E were 0, 2, 5, 6, and 10, respectively, and the number of pigs with damage increased with the spray-coagulation time. In the three-branch damage group, the spray-coagulation time, maximum damage area, and maximum damage depth were all higher than those in the control group (without three-branch damage), and the differences were statistically significant (all P<0.05). Conclusion:The degree of damage to G1 caused by APC is positively correlated with the spray-coagulation time, and damage to the three branches of the Glisson system in G1 is related to the maximum damage area, maximum damage depth, and APC spray-coagulation time.

Résumé
Hilar cholangiocarcinoma(HCCA) is a hotpot and a difficult point in the field of hepatobiliary surgery. HCCA is the most common type of cholangiocarcinoma and is characterized by atypical early clinical manifestations, rapid progression and poor prognosis. There is no specific marker for HCCA and its preoperative diagnosis and evaluation mainly relies on imaging examination. Surgical treatment is still the main treatment, but most patients have lost the opportunity of surgical resection by the time of treatment. In recent years, a large number of studies have been conducted on the diagnosis and treatment of HCCA at home and abroad, and the efficacy of HCCA has been improved. Perioperative management, including the selection of preoperative drainage and perioperative chemoradiotherapy and others, improved postoperative survival. Among them, the application of preoperative radiotherapy and chemotherapy in the field of liver transplantation has achieved quite good results. Targeted therapy and immunotherapy have provided new treatment methods for HCCA. This paper reviews the diagnosis and multimodal treatment of HCCA.

Objective:To explore the clinical efficacy of liver transplantation for Wilson's disease(WD).Methods:From January 1999 to November 2021, clinical data were retrospectively reviewed for 16 recipients with WD undergoing liver transplantation.There were 9 males and 7 females with an age range of 29.5(14~54)years.They were followed up by telephone, outpatient services and hospitalization.The starting point of follow-up was operation date.And recipient death was an endpoint.Postoperative survival, improvement of neuropsychiatric symptom, changes of corneal K-F ring, altered levels of liver function and serum copper-protein at Month 1 post-operation were observed.The follow-up deadline was November 24, 2021.Results:15 recipients underwent classical orthotopic liver transplantation and the other one recipient underwent living-related liver transplantation.No perioperative deaths occurred.All 16 recipients were followed up for 122(6~260)months.The 1-, 5-, and 10-year survival rates were 93.8%、85.2%and 75.8%, respectively.Among 10 recipients with corneal K-F ring positive with varying degrees after operation and was disappeared in 2 recipients at 7 and 11 months.Among 5 recipients with neuropsychiatric manifestation, 4 recipients showed ameliorative neuropsychic symptoms with varying degrees after operation and 1 recipient died.All the levels of liver function and serum copper-protien of all recipients recovered obviously in 1 month and the 1-, 5-, and 10-year post-operation.Conclusions:Classical orthotopic liver transplantation and living-related liver transplantation not only effectively improves copper metabolism of patient with WD and relieves their severe neurological manifestation, but also improves their life and prolongs survival, which is worthy of clinical promotion.
Résumé
Three patients received surgical treatment in Department of Hepatobiliary Surgery of Mengchao Hepatobiliary Hospital from December 2020 to February 2022. Ceftriaxone sodium was given prophylactically before and after operation,and gallbladder silt stones were found by imaging examination on the 3rd, 3rd and 2nd after surgery in 3 patients, respectively. No special treatment was given,after the withdrawal of ceftriaxone sodium for 28, 38 and 48 d,radiographic examination showed that calculi disappeared spontaneously. It is suggested that the pseudolithiasis may be related to administration of ceftriaxone sodium.

Objective:To investigate the application value of three-dimensional (3D) visualization combined with indocyanine green (ICG) fluorescence imaging in anatomical hepatectomy for hepatocellular carcinoma (HCC).Methods:Clinical data of 45 patients with HCC who underwent anatomical hepatectomy in the Department of Hepatobiliary Surgery, the 900th Hospital of Joint Logistic Support Force of People′s Liberation Army from September 2019 to December 2020 were retrospectively analyzed. Among them, 27 patients were males and 18 were females, aged from 28 to 73 years, aged (57.76±10.95) years on average. According to the different surgical methods, all patients were randomly divided into ICG group ( n=24) and control group ( n=21). In ICG group, 15 patients were males and 9 females, aged (58.21±11.81) years on average. Anatomical hepatectomy was performed using 3D visualization combined with ICG fluorescence imaging. In control group, 12 patients were male and 9 female, aged (57.24±11.35) years on average. Conventional anatomical hepatectomy was performed. The operation duration, bleeding volume, the numbers of cases underwent blood transfusion, occlusion durations, days of hospitalization, highest postoperative serum ALT and TBiL, duration of recovery of postoperative serum ALT and TBiL, and incidence of complications were observed. Measurement data with approximately normal distribution were represented by ( Mean± SD) and groups were compared using t test. Measurement data with skewed or uneven distribution were represented by M (rang) and groups were compared using Man-Whitney U test. Count date were compared using Fisher exact test. Results:All the patients underwent successful operations, without perioperative death. In ICG group, the operation duration was 110.50 (44.00-145.00) min and the occlusion durations was (15.17±2.14) min respectively, shorter than 122.00(80.00-255.00) min and (17.29±4.35) min in control group, the difference between the two groups were statistically significant ( Z=-2.002, -2.115; P<0.05). In ICG group, the numbers of cases underwent blood transfusion was 2 cases, less than 8 cases in control group, the difference between the two groups was statistically significant ( χ2=4.147, P<0.05). The bleeding volume, days of hospitalization, highest postoperative serum ALT and TBiL, duration of recovery of postoperative serum ALT and TBiL, postoperative complications between the two groups were not statistically different ( P>0.05). Conclusions:3D visualization combined with indocyanine green fluorescence imaging technique is a feasible surgical method for anatomical hepatectomy. It is helpful for liver surgeons to visualize and recognize the boundary between hepatic segments and improve the safety of anatomic hepatectomy.

Objective To investigate the feasibility of liver transplantation in the treatment of inoperable hilar cholangiocarcinoma. Methods The clinical data for 3 patients with unresectable hilar cholangiocarcinoma who underwent liver transplantation in the Department of Hepatobiliary Surgery of Fuzhou General Hospital of People's Liberation Army from January 2006 to December 2012 were retrospectively analyzed. The patients were followed up by phone, outpatient service, and hospitalization. The starting point of the follow-up was the operation date. The patients death was the end point. The clinical and pathological features, postoperative survival, tumor recurrence, and prognostic factors were observed. The follow-up deadline was December 2017. Results All 3 patients underwent classical orthotopic liver transplantation using retrograde perfusion through inferior vena cava and no perioperative deaths occurred. All 3 patients were followed up for 10 to 132 months. During the follow-up period, of 1 patient who died of tumor recurrence, the pathological TNM stage was T4a N1 M0, and both had Union for International Cancer Control stage Ⅳa, and the tumor-free survival time was 3 months, and the survival time was12 months. Of 1 patient who died of other causes, the pathological TNM stage was T3N1 M0, and both had Union for International Cancer Control stage Ⅲ, and the tumor-free survival time was 12 months, and the survival time was12 months. One case as of the end of follow-up, the patient has survived for 132 months, the pathological TNM staging was T2a NOM0, and both had Union for International Cancer Control stage Ⅱ. Conclusions Lymph node positive and high pathological TNM stage were poor prognosis factor for hilar cholangiocarcinoma who underwent liver transplantation. Patients with early hilar cholangiocarcinoma who don't have lymph node metastasis are expected to benefit from liver transplantation.

Objective To investigate the methods for reconstructing portal vein in liver transplantation patients with grade Ⅳ portal vein thrombosis.Methods Clinical data of 6 patients with grade Ⅳ portal vein thrombosis who underwent liver transplantations were analyzed retrospectively.Different portal vein reconstructing approaches were applied: 4 patients underwent portal vein anastomosis with internal organ varicosis vein (group A),and 2 patients underwent portal vein arterialization (group B). Portal venous flow was monitored by intraoperative ultrasound and postoperative liver function was tested periodically during follow-up.Results In group A,one patient died of celiac infection 2 months post-transplantation.The remaining three patients were followed up for 14-17 months,and their portal veins remained smooth without thrombosis and with mitigated esophageal varicosity.In group B,one patient,with recurrent upper gastrointestinal bleeding,died of celiac infection 47 days after liver transplantation.The patient was followed up for 33 months with satisfactory liver and kidney functions although stomach esophagus varicosity was aggravated.Portal vein blood flow in groups A and B was 1258 ± 345 and 2275 ± 247 ml/min respectively after anastomosis by intraoperative color Dopplar ultrasound monitoring. Aspertate aminotransferase (AST) in group B was significantly lower on the fourth day after liver transplantation,and alanine aminotransferase (ALT) in group B was significantly lower on the 3rd,4th,5th and 6th day after liver transplantation than in group A (all P<0.05).Serum total bilirubin (TBIL) had no statistically significant difference during the 10 days post-operation (P>0.05).Conclusion Patients with grade Ⅳ portal vein thrombosis may achieve a satisfactory clinical effect by reconstructing portal vein through anastomosis of donor portal vein with internal organ? varicosis vein.PVA may be associated with early recovery of graft function and may be an effective remedial measure for patients with grade Ⅳ portal vein thrombosis who undergo liver transplantation.
