Abstract

In this study, it was aimed to investigate the general distribution and characteristics of hydatid cyst (HC) cases in society by a single-center comprehensive study. Three thousand ninety consecutive patients who were followed up and treated for HC in our hospital between January 2001 and December 2020 were analyzed retrospectively. It was determined that HC was seen more in males than females (54.84% and 45.16%, respectively) in childhood and more in females than males in adulthood (59.89% and 40.11%, respectively, P < 0.001). Regarding the living areas, 82.01% of the cases were living in the rural area and 17.99% in the city center (P < 0.001). It was observed that the cases increased significantly in the second ten years (72.36%) compared to the first 10 years (27.64%) (P < 0.001). At least one of the liver or lungs was involved in 95.08% of the cases. The liver was involved in 80.23% of the cases (66.87% in children, 84.94% in adults, P < 0.001) and the lung in 22.91% (38.59% in children, 17.38% in adults, P < 0.001). Other regions’ involvement percentages were as follows: spleen 2.36%, musculoskeletal system 1.59%, kidneys 1.13%, intracranial region 0.91% (2.61% in children, 0.31% in adults, P < 0.001), omentum 0.91%, mediastinum 0.61%, cardiac region 0.58%, pelvic cavity 0.58%, diaphragm 0.55%, pancreas 0.13%, retroperitoneal area 0.13%, ovarian region 0.13%, uterine wall 0.06%, thyroid glands 0.03%, and nasal cavity 0.03%. HC ratio has increased in recent years. Liver involvement is more common in adults than children. Lung and intracranial involvement are more common in children than in adults.
