ABSTRACT

Alveolar echinococcosis proliferates in the form of chronic infiltration and has no obvious symptoms and signs in the early stage, and when attending the hospital, some patients already have one or more complications and invasion of important intrahepatic vessels and bile ducts. The research on peripheral vascular invasion of alveolar echinococcosis may help to determine the best individualized treatment and thus improve the cure rate and prognosis of patients. This article reviews the pathological mechanism, clinical manifestations, imaging, clinical classification, and treatment of alveolar echinococcosis.

ABSTRACT

ObjectiveTo investigate the correlation between systemic immune-inflammation index (SII) and prognosis in patients with hepatic alveolar echinococcosis. MethodsA retrospective analysis was performed for the clinical data of 242 patients who were admitted to Department of Hepatopancreatobiliary Surgery, Qinghai University Affiliated Hospital, from January 2015 to December 2018 and underwent surgery for hepatic alveolar echinococcosis, and SII was calculated. The chi-square test was used for comparison of categorical data between two groups, and a Spearman correlation analysis was performed. The receiver operating characteristic (ROC) curve was used to determine the optimal cut-off value of SII; the Kaplan-Meier method was used to plot survival curves and analyze overall survival time in the two groups, and the log-rank test was used for comparison of survival rates between the two groups; univariate and multivariate Cox regression analyses were used to identify the influencing factors for the prognosis of patients with hepatic alveolar echinococcosis. ResultsThe Spearman correlation analysis showed that SII was positively correlated with the postoperative fatality rate of patients with hepatic alveolar echinococcosis (r=0.267, P<0.001). The ROC curve showed that the optimal cut-off value of SII before surgery was 758.92, and based on this, 242 patients with hepatic alveolar echinococcosis were divided into low SII (SII ≤758.92) group with 126 patients and high SII (SII >758.92) group with 116 patients. The low SII group had 1-, 3-, and 5-year survival rates of 98.20%, 88.47%, and 6610%, respectively, and the high SII group had 1-, 3-, and 5-year survival rates of 90.80%, 53.05%, and 27.40%, respectively. The low SII group had a cumulative survival rate of >50% and a mean survival time of 55.584 months (95% confidence interval[CI]: 53550-57.617), while the high SII group had a cumulative survival rate of <50%, a mean survival time of 39.384 months (95% CI: 35.070-43.698), and a median survival time of 43 months (95% CI: 34.694-51.306). The low SII group had a significantly better survival rate than the high SII group, and there was a significant difference in overall survival rate between the two groups (χ2=46.979, P<005). The univariate analysis showed that SII >758.92 (hazard ratio [HR]=5.907, 95% CI: 3.386-10.306, P=0.001) was an influencing factor for the overall survival time of patients with hepatic alveolar echinococcosis, and the multivariate Cox regression analysis showed that preoperative peripheral blood SII (HR=3.507, 95% CI: 1.911-6.435, P=0.001) was an independent risk factor for the overall survival rate of patients with hepatic alveolar echinococcosis. ConclusionPreoperative SII level is clearly correlated with the prognosis of patients with hepatic alveolar echinococcosis and can thus be used as a clinical indicator to evaluate the prognosis of patients. The higher the peripheral blood SII before surgery, the worse the prognosis of patients.

ABSTRACT

Objective:To investigate the effect of hepatitis B virus (HBV) infection in patients with hepatic alveolar echinococcoisis after surgical resection and determine the differences of liver function between patients with different HBV-DNA levels.Methods:Patients were selected from January 2014 to July 2018 in the Affiliated Hospital of Qinghai University. Twenty-eight patients with hepatitis B and hepatic alveolar echinococcoisis were included in the experimental group, and 20 patients with hepatic alveolar echinococcoisis but without hepatitis B virus were included in the control group. Based on HBV-DNA level, the experimental group was divided into low-level group (HBV-DNA level<200 IU/ml, n=6), intermediate-level group (HBV-DNA level 200-20 000 IU/ml, n=15) and high level group (HBV-DNA level>20 000 IU/ml, n=7). Comparison of complications and liver function after liver resection in two groups.Univariate and multivariate logistic regression were used to analyze the influential factors of postoperative complications in patients.Comparison of postoperative liver function indexes in patients with different HBV-DNA levels. Results:In the control group, postoperative total bilirubin 10.6(8.3, 16.9) μmol/L, direct bilirubin 5.3(3.4, 10.0) μmol/L, prothrombin time 13.6(13.0, 15.8)s, and the incidence of complications 25.0%(5/20), were better than the experimental group 12.6(8.4, 46.9) μmol/L, 6.7(3.1, 26.4) μmol/L, 15.4(13.5, 18.1)s, 78.6% (22/28), the differences were statistically significant significance (all P<0.05). Multivariate logistic analysis showed that patients with HBV infection ( OR=4.593, 95% CI: 1.128-18.708) and intraoperative blood loss ≥1 000 ml ( OR=2.200, 95% CI: 1.106-4.378) were the hepatic alveolar echinococcoisis independent risk factors for postoperative complications. There were no significant differences in total bilirubin and albumin between the three groups of patients with different HBV-DNA levels ( P>0.05). Conclusion:Patients with HBV and hepatic alveolar echinococcoisis have worse liver function and are more prone to complications after surgical resection, but there is no significant difference in liver function among patients with different HBV-DNA levels.

ABSTRACT

Objective To preliminarily study the use of indocyanine green in hepatic alveolar echinococcosis surgery.Methods The data of 13 patients with hepatic alveolar ecbinococcosis treated at the Affiliated Hospital of Qinghai University from May 2017 to May 2018 with laparotomy and intraoperative indocyanine green injection were retrospectively studied.Images were collected by the fluorescence acquisition system.Results There were 7 females and 6 males,with an average age of (37.9±14.7) years.The mean weight was (57.4±11.3) kg.Except for one patient of Han nationality,the rest were Tibetans.The lesions were not visualized but normal liver tissues emitted green fluorescence.One patient had a slightly enhanced fluorescence circle around the lesion.The fluorescence intensity of some areas were between normal liver tissues and the lesion,which were suspected to be the marginal zone (which needed to be confirmed by pathology).Three patients (23.1%,3/13) had small lesions on the liver surface,2 were not found by imaging examination,and 1 showed strip calcification on CT.No residual lesions in the liver (except for the microwave ablated lesions) were found after resection.No postoperative complications occurred in all the patients.Seven patients were followed up and no recurrence was found.Conclusions Fluorescence imaging of indocyanine green has the advantages of detecting small and residual lesions in surgery carried out for hepatic alveolar echinococcosis.More studies are needed to confirm the findings.
