The Retrospective Annual Surgical Incidence of Cystic Echinococcosis in Sivas, Turkey

Cystic echinococcosis is an important public health problem in our region. The aim of this study was to assess the surgical incidence of cystic echinococcosis in Sivas, Turkey. A retrospective follow‐up study was carried out between 1997 and 2004. The mean age of 124 men (39.2%) and 192 women was 36.4 years. The liver was the primary site of cyst development (76.6%), followed by the lungs (19.9%), the spleen (5.4%), the kidneys (3.5%) and the peritoneal cavity (3.2%). Mean annual surgical incidence was 6.4 per 100 000 inhabitants for a 7‐year period. The most common site of recurrence was the liver. Hepatic cysts were more frequently infected than pulmonary cysts (P < 0.05). In those patients with an infected cyst, the mean circulating eosinophil level was significantly lower than in those without. Rupture and infection were more common in men (P < 0.01). In conclusion, serious structural, legislative, surveillance, prevention and control measures for echinooccus should be undertaken in our region.
