ObjectiveTo analyze the efficacy and safety of complete excision of the external capsule in the treatment of hepatic echinococcosis.MethodsThe clinical data of 90 patients with hepatic cystic echinococcosis admitted to our hospital from January 2016 to March 2018 were retrospectively analyzed. According to the different surgical methods, this patients were divided into two groups: the partial hepatectomy group and complete excision of the external capsule group, 45 cases in each group. The patient's general condition and the situation during hospitalization were analyzed, and the intraoperative conditions, postoperative complications, recurrence and mortality after one year in different surgical methods were compared.ResultsThe operative time and intraoperative blood loss in the partial hepatectomy group was significantly longer or more than that in the complete excision of the external capsule group (P<0.05), respectively. There was no significant difference between the two groups in hospitalization time (P>0.05). The incidence of postoperative complications was 11.11% in the partial hepatectomy group and 8.88% in the complete excision of the external capsule group. There was no significant difference between the two groups (P>0.05). After 1 year of followed-up, the recurrence rate of the partial hepatectomy group was 4.44%, and there was no recurrence in the complete excision of the external capsule group, and there was no significant difference between the two groups (P>0.05). There was no death in both groups.ConclusionsIn the surgical treatment of hepatic cystic echinococcosis, the most appropriate surgical method should be selected according to the specific conditions of the patient, and the complete excision of the external capsule has higher therapeutic effect and safety in the treatment of hepatic echinococcosis. It is worthy of clinical promotion.
