摘要

Echinococcosis infestations are caused by the larval tapeworm of genus Echinococcus. The disease is distributed globally. There are two main types of these parasitic infestations in clinical practice: cystic echinococcosis (CE) and alveolar echinococcosis (AE) caused by Echinococcus granulosus and Echinococcus multilocularis, respectively. Regular long-term use of oral benzimidazoles is a feasible treatment for hepatic echinococcosis. However, owing to the potential serious side effects and heavy economic burdens caused by lifelong drug administration, most people prefer to choose more radical surgical approaches. The treatment of hepatic hydatid cyst may be medical therapy, percutaneous drainage, or surgical intervention which can be via a conventional or laparoscopic approach. Surgical treatment is considered the best therapeutic choice for uncomplicated hydatid disease of the liver. One of the major advantages of surgical treatment is that it results in complete parasitic eradication, it allows for treatment or prevention of complications and it minimizes the risk of relapse. Surgical treatment of hepatic hydatid cyst can be considered as radical surgery or conservative surgery. Radical surgical techniques include pericystectomy and hepatic resection, whereas conservative surgical techniques are based on the drainage of the cyst contents, sterilization of the residual cavity, and partial cyst resection. Most reports in the literature suggested that recurrence and complication rates tend to be higher with conservative surgery as compared to those with radical surgery. The high recurrences attributed to conservative surgery are usually caused by failure of complete removal of the endocysts and/or their dissemination during operative intervention.
