  • Preliminary study of reasonable and feasible safe distance for radical resection of hepatic alveolar echinococcosis

    ObjectiveTo explore the reasonable and feasible safe distance for radical resection of hepatic alveolar echinococcosis (HAE). MethodsLiver samples were collected prospectively from 20 HAE patients (from Jan. 2019 to Jun. 2019) undergoing liver resection in West China Hospital of Sichuan University. A total of three samples containing lesion and adjacent liver tissue were collected from each patient, which were divided into lesion group, 0 to0.5 cm liver tissue group (contained 0.5 cm), 0.5 to 1.0 cm liver tissue group (contained 1.0 cm), 1.0 to 1.5 cm liver tissue group (contained 1.5 cm), and 1.5 to 2.0 cm liver tissue group (contained 2.0 cm). Comparisons of the Cox1 expressionand the liver fibrosis area between HAE lesion and adjacent liver tissues were performed. ResultsBoth expression of Cox1 and fibrosis area in HAE lesion were significantly higher than those in the adjacent liver tissues (P<0.000 1). However, there was no significant difference among the four kinds of adjacent liver tissues (P>0.05). There was a significant positive correlation between the expression of Cox1 and the fibrosis area both in HAE lesion and adjacent liver tissues (P<0.05). ConclusionsBoth the expression of Cox1 and degree of the liver fibrosis are significant higher in HAE lesion comparing to adjacent liver tissues, however, no significant difference is found among adjacent liver tissues. Consequently, a safe distance of 0.5 cm may be reasonable and feasible on the basis of the criteria for sample collection in the study.
