Clinical effect of surgery in treatment of calcified hepatic cystic echinococcosis

Objective To investigate the clinical effect of surgery in the treatment of calcified hepatic cystic echinococcosis. Methods A retrospective analysis was performed for the clinical data of 16 patients with 20 calcified hepatic hydatid cysts who underwent surgical treatment( total pericystectomy,subtotal pericystectomy,and endocystectomy) in The First Affiliated Hospital of Shihezi University School of Medicine from November 2015 to February 2019. Results Of all 16 patients,1 underwent total pericystectomy,5 underwent endocystectomy,and 10 underwent subtotal pericystectomy. One patient experienced bile leakage after surgery since the cyst ruptured and entered the bile duct and there was a biliary fistula in the outer wall of the cyst before surgery,and the other patients had no residual cavity complications including residual cavity effusion and infection,bile leakage,or jaundice. There was no death and recurrence after operation. Conclusion Surgical treatment is necessary for non-stationary calcified hepatic cystic echinococcosis. Total pericystectomy is not suitable,while subtotal pericystectomy may be the preferred surgical method,especially when the calcified hepatic hydatid cyst is located near the porta hepatis or the intrahepatic and extrahepatic vessels and there is no obvious lacunae between the adventitia and the outer cyst. Endocystectomy can be selected when hepatic hydatid cyst ruptures.
