Clinical study of standard residual liver volume and transient elastography in predicting poor prognosis of patients after hemihepatectomy

BACKGROUND Liver cancer resection,especially in patients with hemihepatectomy or extended hemihepatectomy,often leads to poor prognosis,such as liver insufficiency and even liver failure and death,because the standard residual liver volume(SRLV)cannot be fully compensated after surgery.AIM To explore the risk factors of poor prognosis after hemihepatectomy for hepatocellular carcinoma and evaluate the application value of related prognostic approaches.METHODS The clinical data of 35 patients with primary liver cancer in Nantong Third People's Hospital from February 2016 to July 2020 were retrospectively analyzed.The receiver operating characteristic curve was created using medcac19.0.4 to compare the critical values of the SRLV in different stages of liver fibrosis after hemihepatectomy with those of liver dysfunction after hemihepatectomy.It was constructed by combining the Child-Pugh score to evaluate its application value in predicting liver function compensation.RESULTS The liver stiffness measure(LSM)value and SRLV were associated with liver dysfunction after hemihepatectomy.Logistic regression analysis showed that an LSM value≥25 kPa[odds ratio(OR)=6.254,P<0.05]and SRLV≤0.290 L/m^(2)(OR=5.686,P<0.05)were independent risk factors for postoperative liver dysfunction.The accuracy of the new liver reserve evaluation model for predicting postoperative liver function was higher than that of the Child-Pugh score(P<0.05).CONCLUSION SRLV and LSM values can be used to evaluate the safety of hemihepatectomy.The new liver reserve evaluation model has good application potential in the evaluation of liver reserve function after hemihepatectomy.

Predicting liver function after hemihepatectomy in patients with hepatocellular carcinoma using different modalities

In response to Dr.Yue et al's study on prognostic factors for post-hemihep-atectomy outcomes in hepatocellular carcinoma(HCC)patients,this critical review identifies methodological limitations and proposes enhancements for future research.While the study identifies liver stiffness measure and standard residual liver volume as potential predictors,concerns regarding small sample size,reliance on biochemical markers for safety assessment,and inadequate ad-justment for confounding variables are raised.Recommendations for rigorous methodology,including robust statistical analysis,consideration of confounding factors,and selection of outcome measures with clinical components,are proposed to strengthen prognostic assessments.Furthermore,validation of novel evaluation models is crucial for enhancing clinical applicability and advancing understanding of postoperative outcomes in patients with HCC undergoing hem-ihepatectomy.

Displacement of the Residual Liver Cavity in Laparoscopic Echinococcectomy

Aim: This article aimed to investigate the analysis of various methods for eliminating the residual liver cavity after laparoscopic echinococcectomy in patients. Methods: The authors used the following methods of eliminating the residual cavity: omentoplasty (36.8%), abdominalization (30%), drainage of the residual cavity (26.2%), and a combination of omentoplasty with drainage of the residual cavity (7%). Results: In the postoperative period, complications occurred in 2 (3.5%) cases in the form of bile leakage from the residual liver cavity. Conclusions: It is recommended to use abdominalization and omentoplasty when choosing a method for eliminating the residual liver cavity.
