title: Hydatid Cyst Surgeries in Patients Referred to Hospitals in East Azerbaijan Province during 2009-2011.
abstract: BACKGROUND
  Hydatidosis, as the most important zoonotic parasitic disease in Iran, has posed many health and economic losses. This study was conducted to investigate the demographic characteristics of hydatid cyst surgeries in hospitals of East Azerbaijan Province, Northwest of Iran.
  
  
  METHODS
  Demographic characteristics of all patients with hydatid cyst surgery in hospitals of the province, during 2009-2011 were gathered including age, gender, occupation, number and location of the cyst, clinical symptoms, place of residence and history of contact with dog. They were extracted from reports of health center and were analyzed using STATA 11 software.
  
  
  RESULTS
  Out of 52 hydatid cyst surgeries, 27 cases were females. Mean age of patients was 38.3 yr. Liver was reported as the most involved organ. The most clinical symptoms were abdominal and liver pain. Housewives comprised the most victims of the disease. Forty seven percent of patients had one cyst and 59% had the history of contact with dog. The majority of the patients were living in rural areas.
  
  
  CONCLUSIONS
  Due to the high costs of diagnosis and treatment of hydatidosis, collecting data on the prevalence and transmission of the disease as well as on vulnerable groups seems to be essential as the first step in controlling and preventing the disease.
