  • Theory and practice of lesioned bile duct tree drainage resection in the diagnosis and treatment of benign biliary tract diseases

    The global incidence of benign biliary tract diseases is high. Not only its anatomical variations are complex and the disease heterogeneity is strong, but also its preoperative assessment methods, surgical techniques and diagnostic and treatment strategies need to be improved. Consequently, patients have many perioperative complications and a poor long-term prognosis. According to the anatomical characteristics of the biliary tract and the pathophysiological characteristics of benign biliary diseases, we propose the surgical treatment concept of benign biliary tract diseases with the removal of the diseased bile duct tree drainage as the core, which is different from the traditional biliary surgery that takes “patency and obstruction” as the focus of treatment, and “alleviates symptoms” as the treatment goal. Through a series of improvements such as preoperative evaluation, surgical planning, surgical operations, and postoperative management, we have designed a series of innovative diagnosis and treatment strategies and procedures with the goal of curing biliary diseases, with a view to changing the diagnosis and treatment status of biliary surgery. We hope that can change the current the diagnosis and treatment status of biliary surgery.

  • Macrophages, a new hope for the treatment of liver fibrosis

    Evidence from numerous animal models and clinical studies in recent years has demonstrated that macrophages play an important role in the regulation of liver fibrosis regression. The safety and efficacy of utilizing autologous macrophages for the treatment of liver fibrosis have been demonstrated in patients and shows promising application prospects, but the therapeutic effects need to be improved. Cirrhotic liver undergoes a process of marked extracellular matrix degradation after partial hepatectomy surgery, and single-cell sequencing identified multiple restorative macrophage subsets that express different matrix metalloproteinases (MMPs) at high levels. Future efforts to further characterize this population of macrophages and improve their enrichment in the liver may allow macrophage therapy to be a highly effective strategy to reverse liver fibrosis.

  • Ex vivo liver resection and autotransplantation for end-stage hepatic alveolar echinococcosis: Risk factors and prediction model for severe postoperative complications

    ObjectiveTo investigate the risk factors affecting severe postoperative complications (Clavien-Dindo classification Ⅲa or higher) in patients with end-stage hepatic alveolar echinococcosis (HAE) underwent ex vivo liver resection and autotransplantation (ELRA), and to develop a nomogram prediction model. MethodsThe clinical data of end-stage HAE patients who underwent ELRA at the West China Hospital of Sichuan University from January 2014 to June 2024 were retrospectively analyzed. The logistic regression was used to analyze the risk factors affecting severe postoperative complications. A nomogram prediction model was established basing on LASSO regression and its efficiency was evaluated using receiver operating characteristic (ROC) curve, calibration curve, and decision curve analysis. Simultaneously, a generalized linear model regression was used to explore the preoperative risk factors affecting the total surgery time. Test level was α=0.05. ResultsA total of 132 end-stage HAE patients who underwent ELRA were included. The severe postoperative complications occurred in 47 (35.6%) patients. The multivariate logistic analysis results showed that the patients with invasion of the main trunk of the portal vein or the first branch of the contralateral portal vein (type P2) had a higher risk of severe postoperative complications compared to those with invasion of the first branch of the ipsilateral portal vein (type P1) [odds ratio (OR) and 95% confidence interval (CI)=8.24 (1.53, 44.34), P=0.014], the patients with albumin bilirubin index (ALBI) grade 1 had a lower risk of severe postoperative complications compared to those with grade 2 or higher [OR(95%CI)=0.26(0.08, 0.83), P=0.023]. Additionally, an increased total surgery time or the autologous blood reinfusion was associated with an increased risk of severe postoperative complications [OR(95%CI)=1.01(1.00, 1.01), P=0.009; OR(95%CI)=1.00(1.00, 1.00), P=0.043]. The nomogram prediction model constructed with two risk factors, ALBI grade and total surgery time, selected by LASSO regression, showed a good discrimination for the occurrence of severe complications after ELRA [area under the ROC curve (95%CI) of 0.717 (0.625, 0.808)]. The generalized linear regression model analysis identified the invasion of the portal vein to extent type P2 and more distant contralateral second portal vein branch invasion (type P3), as well as the presence of distant metastasis, as risk factors affecting total surgery time [β (95%CI) for type P2/type P1=110.26 (52.94, 167.58), P<0.001; β (95%CI) for type P3/type P1=109.25 (50.99, 167.52), P<0.001; β (95%CI) for distant metastasis present/absent=61.22 (4.86, 117.58), P=0.035]. ConclusionsFrom the analysis results of this study, for the end-stage HAE patients with portal vein invasion degree type P2, ALBI grade 2 or above, longer total surgery time, and more autologous blood transfusion need to be closely monitored. Preoperative strict evaluation of the first hepatic portal invasion and distant metastasis is necessary to reduce the risk of severe complications after ELRA. The nomogram prediction model constructed based on ABLI grade and total surgery time in this study demonstrates a good predictive performance for severe postoperative complications, which can provide a reference for clinical intervention decision-making.

  • Effect of “in situ first” ex vivo liver resection and autologous liver transplantation for end stage hepatic alveolar echinococcosis

    Objective To explore the effect of “in situ first” ex vivo liver resection and autologous liver transplantation (ELRA) for end stage hepatic alveolar echinococcosis (HAE). Methods The clinicopathologic data of 85 end stage HAE cases were initially scheduled underwent ELRA from June 2019 to May 2022 in the Sichuan Provincial People’s Hospital were collected retrospectively. The included cases were operated under “in situ first” ERLA principle. The analyzed data included the final surgical style, operative time, time of anhepatic phase and intraoperative blood transfusion volume for ELRA cases. Results All the included 85 cases underwent radical HAE lesions resection and without perioperative death occurred. According to the principle of “in situ first”, 57 cases underwent HAE lesions resection combined vascular reconstruction without ex vivo liver resection (in situ resection group); 1 case underwent auxiliary partial autologous liver transplantation, and 27 cases underwent ERLA procedures (ELRA group). In the in situ resection group, the operative time was 210–750 min, (380±134)min, and the intraoperative blood transfusion was 0–3 250 mL with a median of 0 mL. In the ELRA group, the operative time was 450–1 445 min, (852±203) min, and the intraoperative blood transfusion was 0–6 800 mL with a median of 1 960 mL. The operative time and the amount of blood transfusion in the ELRA group were longer or more than those in the in situ resection group. The time of anhepatic phase for the ELRA group was 60–480 min, (231±83) min. On the 5th day after operation, except that the total bilirubin and direct bilirubin in the ELRA group were higher than those in the in situ resection group, the other indexes of liver function were similar between the two groups. The postoperative stay in ICU and the total postoperative hospital stay in the ELRA group were longer than those in the in situ resection group. Conclusions The advantage of “in situ first” ERLA principle for end stage HAE patients include resecting the HAE lesions radically without ex vivo liver resection and alleviating the hepatic ischemia and reperfusion injury. For the inevasible ELRA cases, “in situ first” principle could shorten the anhepatic phase and reduce intraoperative blood loss, and turn some cases to auxiliary partial autologous liver transplantation, which will reduce the risk of postoperative hepatic failure.

  • Comprehensive treatment strategy for hepatocellular carcinoma centered on surgical intervention

    Hepatocellular carcinoma (HCC) is one of the most prevalent malignant tumors worldwide. Although surgery remains the key approach for achieving long-term survival, the majority of patients are ineligible for surgery at the time of initial diagnosis, resulting in suboptimal overall treatment outcomes. This paper reviews the current treatment strategies for HCC, with a particular focus on comprehensive treatment plans centered around surgery. It explores the status and advancements in multidisciplinary treatment approaches, including preoperative conversion therapy, minimally invasive surgery, and postoperative adjuvant therapies. Through the adoption of rational comprehensive treatment strategies, it is anticipated that the therapeutic outcomes and quality of life for HCC patients can be improved.

    Objective To summarize the methods, safety, and efficacy of the ex vivo liver resection followed by autotransplantation in the treatment of advanced hepatic alveolar echinococcosis (HAE). Method A retrospective analysis of clinical data and follow-up data in 21 cases who received ex vivo liver resection followed by autotransplantation in the treatment of HAE from February 2014 to December 2016 in West China Hospital was performed. Results All the patients successfully underwent ex vivo liver resection followed by autotransplantation and no death happened during operation. The median weight of remnant liver was 701.4 g (360–1 300 g), the average operation time were 13.6 h (9.4–19.5 h), the anhepatic phase time were 180–455 min with median of 314 min. The average of intraoperative blood loss were 2 379 mL (1 200–6 000 mL). The average of patients entered red blood cell suspension were 10.6 u (0–39.5 u), the average of fresh frozen plasma were 1 377 mL (0–6 050 mL) , of which 7 patients received autologous blood transfusion, with average of 1 578 mL (500–3 700 mL). The average of postoperative hospital stay were 23.5 days (4–51 days). Postoperative complications occurred in 12 patients during hospitalization, and 4 cases of postoperative complications were in grade Clavien-Dindo Ⅲ or above, 2 cases of grade Ⅴ (died). During the follow-up period, 19 patients were followed for a median of 16.2 months (3–38 months), no HAE recurrence or metastasis was found, only 1 patient were lost follow-up after surgery for 12 months. Massive ascites and hyponatremia were found in 1 patient who was diagnosis as left hepatic vein stenosis at the end of the 3 months after operation. The patient was cured after interventional treatment of hepatic vein stent implantation and angioplasty. Conclusions The ex vivo liver resection followed by autotransplantation provides radical treatment for patients with advanced HAE, but the surgery is difficult and has high risk of postoperative complications. The detailed preoperative evaluation, intraoperative pipeline reconstruction reasonably, and fine postoperative management can improve the patient’s survival, and reduce the rate of complications.

  • Application of hepatic vein reconstruction with various vascular materials in treatment of end-stage hepatic alveolar echinococcosis by ex-vivo liver resection and autologous liver transplantation

    ObjectiveTo summarize the key operative points and efficacy of ex-vivo ex-vivo liver resection and autologous liver transplantation (ELRA) using various vascular materials for hepatic vein reconstruction in the treatment of end-stage hepatic alveolar echinococcosis (HAE). MethodThe clinicopathologic data of a patient with end-stage HAE who underwent ELRA combined with complex hepatic vein reconstruction were retrospectively analyzed. ResultsThe patient was a 60-year-old male who was admitted to the Sichuan Provincial People’s Hospital due to giant alveolar hydatid in the liver, with a body weight of 60 kg and a standard liver volume of 1 024.5 mL. The imaging showed that the hydatid invaded the first and second hepatic portals, middle hepatic vein, left hepatic vein, and retrohepatic inferior vena cava. The three-dimensional reconstruction of CT showed that the residual liver volume was 1 270.6 mL. The patient received supportive treatment after admission and underwent ELRA following strict evaluation. Intraoperatively, it was found that the multiple hepatic veins and retrohepatic inferior vena cava were widely invaded. The liver was split in vivo and the mass was excised ex vivo by “in vivo first” principle. The hepatic vein was repaired and reconstructed into a wide mouth outflow tract using allogeneic veins, autologous inferior mesenteric vein, and hepatic round ligaments, then performed the autotransplantation by wide mouth outflow-artificial inferior vena cava anastomosis (end to side). The operative time was 16 h, and the intraoperative blood loss was approximately 2 000 mL. FK506 was orally administered after operation, and low-molecular-weight heparin sodium was administered 24 h later for anticoagulation. The patient was returned to the general ward on the 6th day after the operation, and the enhanced CT scan showed that the hepatic outflow tract was unobstructed, without stenosis and thrombosis, and the patient was discharged on day 18 after the operation. The patient was pathologically diagnosed with alveolar echinococcosis. ConclusionsFrom the results of this case, combination of multiple vascular materials to reconstruct the hepatic outflow tract is an optional procedure for ELRA in treatment of end-stage HAE. Strict preoperative evaluation, skillful vascular anastomosis technique, and postoperative anticoagulation are important measures to maintain patency of postoperative reconstruction vessel.
