Successful management and technical aspects of major liver resection in children: A retrospective cohort study

Optimal treatment of patients with various types of liver tumors or certain liver diseases frequently demands major liver resection, which remains a clinical challenge especially in children.Eighty seven consecutive pediatric liver resections including 51 (59%) major resections (resection of 3 or more hepatic segments) and 36 (41%) minor resections (resection of 1 or 2 segments) were analyzed. All patients were treated between January 2010 and March 2018. Perioperative outcomes were compared between major and minor hepatic resections.The male to female ratio was 1.72:1. The median age at operation was 20 months (range, 0.33–150 months). There was no significant difference in demographics including age, weight, ASA class, and underlying pathology. The surgical management included functional assessment of the future liver remnant, critical perioperative management, enhanced understanding of hepatic segmental anatomy, and bleeding control, as well as refined surgical techniques. The median estimated blood loss was 40 ml in the minor liver resection group, and 90 ml in major liver resection group (P < .001). Children undergoing major liver resection had a significantly longer median operative time (80 vs 140 minutes), anesthesia time (140 vs 205 minutes), as well as higher median intraoperative total fluid input (255 vs 450 ml) (P < .001 for all). Fourteen (16.1%) patients had postoperative complications. By Clavien-Dindo classification, there were 8 grade I, 4 grade II, and 2 grade III-a complications. There were no significant differences in complication rates between groups (P = .902). Time to clear liquid diet (P = .381) and general diet (P = .473) was not significantly different. There was no difference in hospital length of stay (7 vs 7 days, P = .450). There were no 90-day readmissions or mortalities.Major liver resection in children is not associated with an increased incidence of postoperative complications or prolonged postoperative hospital stay compared to minor liver resection. Techniques employed in this study offered good perioperative outcomes for children undergoing major liver resections.

Efficacy and Safety of Transjugular Intrahepatic Portosystemic Shunt Creation for Budd-Chiari Syndrome: A Systematic Review and Meta-Analysis

PurposeTo assess the critical role of transjugular intrahepatic portosystemic shunt (TIPS) in the management of Budd-Chiari syndrome (BCS), as the data with respect to the safety and outcome of TIPS in patients with BCS are scarce because of the rarity of the disease.Materials and MethodsA comprehensive search of literature of various databases from 2000 to October 2021 was conducted for studies evaluating the outcome of TIPS in patients with BCS. The primary outcomes of the analysis were technical and clinical success, adverse events and mortality associated with TIPS, dysfunction of TIPS, need for TIPS revision, need for liver transplantation (LT), and 1-year survival.ResultsA total of 33 studies (1,395 patients) were included in this meta-analysis. The pooled rates and 95% confidence intervals of various outcomes were 98.6% (97.6–99.7) for technical success, 90.3% (86.0–94.6) for clinical success, 10.0% (6.5–13.6) for major adverse events, 0.5% (0.2–1.0) for TIPS-related mortality, 11.6% (7.8–15.4) for post-TIPS hepatic encephalopathy (HE), 40.1% (32.5–47.7) for TIPS dysfunction, 8.6% (4.9–12.4) for the need for TIPS revision, 4.5% (2.8–6.2) for the need for LT, and 94.6% (93.1–96.1) for 1-year survival. Publication bias was seen with all outcomes except for post-TIPS HE, TIPS dysfunction, and the need for LT.ConclusionsThe existing literature supports the feasibility, safety, and efficacy of TIPS in the treatment of BCS. Deciding the optimal timing of TIPS in BCS needs further studies.     

Liver fibrosis scores and risk of liver-related mortality in young adults with chronic hepatitis B: A cohort study

The predictive role of noninvasive liver fibrosis scores on liver-related mortality in patients with chronic hepatitis B below 40 years of age remains unclarified. We examined the association of liver fibrosis scores with liver-related mortality in young (<40 years) and older adults with hepatitis B virus (HBV) infection. A cohort study was performed in 21,360 HBsAg-positive Korean adults without liver cirrhosis or liver cancer at baseline who were followed up for up to 18 years. The liver fibrosis scores were determined using the fibrosis-4 score (FIB-4) and aspartate transaminase to platelet ratio index (APRI). Patients’ vital status and cause of death were ascertained through the National Death Records. During a median follow-up of 10.2 years, 283 liver-related deaths were identified (liver-related mortality, 127.4/10⁵ person-years). The liver fibrosis scores were significantly associated with increased risks of liver-related mortality; this association did not differ by age group (<40 vs. ≥40 years). The multivariable-adjusted hazard ratios with 95% confidence intervals for liver-related mortality comparing intermediate and high to low FIB-4 scores were 4.23 (1.99–9.00), and 15.16 (5.18–44.38), respectively, among individuals under 40, and 4.46 (3.03–6.56) and 22.47 (15.11–33.41), respectively, among older individuals. These associations were similar in analyses using APRI. In this cohort of HBsAg-positive individuals, the liver fibrosis scores were associated with increased risks of liver-related mortality in young and older adults. The liver fibrosis scores have a role in predicting liver mortality, even in young adults with HBV.     

HBV-ACLF患者血清miR-122和 HMGB1水平及其与病情、预后的关系

[摘要]　目的　探究HBV相关慢加急性肝衰竭（HBV-related acute-on-chronic liver failure, HBV-ACLF）患者血清中微小核糖核酸（microRNA, miR）-122和高迁移率族蛋白1（high-mobility group box-B1, HMGB1）水平及其与病情、预后的关系。方法　回顾性分析2016年1月—2018年1月我院收治的120例HBV-ACLF患者的一般及临床资料。根据临床结局，将患者分为存活组（53例）和死亡组（67例）。比较2组患者的一般资料、实验室检查指标及血清miR-122、HMGB1水平。多因素Logistic回归分析影响患者预后的因素。Pearson检验分析miR-122、HMGB1水平分别与TBIL、PA、终末期肝病评分模型（the model of end-stage liver disease score, MELD）评分的相关性。ROC曲线分析miR-122和HMGB1水平对患者的死亡预测价值，获得最佳临界值。根据临界值将患者分为A组、B组和C组，用Kaplan-Meier法绘制生存曲线，比较3组患者在3年随访期间的生存率。结果　存活组和死亡组患者的年龄、身体质量指数、并发症、病情分期、MELD评分、ALB、球蛋白、TBIL、ALT、AST、LDH、PT、PTA、HBV DNA、miR-122、HMGB1相比，差异均具有统计学意义（P均＜0.05）。年龄、并发症、病情分期、MELD评分、TBIL、PT、PTA、miR-122、HMGB1均是影响患者预后的危险因素（P均＜0.05）。miR-122、HMGB1水平分别与TBIL、MELD评分呈显著正相关，与PTA呈显著负相关（P均＜0.05）。miR-122和HMGB1预测患者死亡的最佳临界值分别为31.42和14.56 μg/L。A组患者预后3年内生存率显著高于B组和C组（P均＜0.05）。结论　miR-122和HMGB1水平与HBV-ACLF患者的病情和死亡预后密切相关，可间接反映患者的病情严重程度，在HBV-ACLF的诊断及预后中具有重要价值。
