Abstract
Hydatid disease is caused by the tapeworm Echinococcus granulosus and it is an endemic parasitic disease of the Mediterranean countries. Although the liver is the most involved organ by this disease, hydatidosis can be found anywhere in the human body. Rare forms of location may pose diagnostic and therapeutic dilemmas. Herein we report our experience with unusual located hydatid disease diagnosed and treated at our center the last 33 years. A total of 233 patients were treated for echinococcosis (91 males: 39 % and 142 females: 61 %) between 1980 and 2013 at our center. 18 of them (7, 8 %) with uncommon located hydatid disease, were analyzed retrospectively. 18 patients (8 males and 10 females) were presented with unusual location of hydatid disease in our series. Two of them had only extrahepatic cysts (0, 9 %). A total of 64 hydatid cysts with unusual location were analyzed. The most prevalent extrahepatic sites were peritoneal cavity and spleen. Total cystectomy with or without tube drainage or omentopexy was performed for hydatid cysts of the peritoneal cavity in our series. Splenectomy was performed in all cases of splenic hydatidosis. The mean time of post operative stay was 16, 3 days (range 7–35 days), morbidity 11 % and mortality 5, 4 %. Although echinococcosis is found most often in the liver and lungs, it seems that any organ can be involved by this zoonotic disease. The operating surgeon must always consider the possibility of unusual location of echinococcal cyst when dealing with patients with cystic mass in endemic areas, because any misinterpretation may result in unfavorable outcomes.
