[Study of hydatid cyst in hospitalized patients with operation in Chaharmahal va Bakhtiary province [1988-2007]]

ABSTRACT

Hydatid cyst disease is one of the most common zoonotic diseases which is mostly due to the inhabitance of Echinococus granulosus larva stage. Iran is one of the hyper-endemic areas for this disease and operation is still the best way for its treatment. It is very important to know the epidemiological aspects of this disease for control and prevention programs. The aim of this study was to evaluate hydatid cyst disease in hospitalized patients with operation in Chaharmahal va Bakhtiary province from 1988 to 2007. In this retrospective-descriptive study patients who were hospitalized due to hydatid cyst operation in Shahrekord Ayatollah Kashani, Brougen Hazrat Vali - Asr and Farsan Seyed- Alshohadah hospitals during 1988-2007 were recruited. Data were collected using questionnaire and were analyzed by chi-square test. Our data showed that from the total of 144 patients, 98 persons were female and 46 cases were male. While the youngest case was an 11 year old boy, the oldest patient was 92 years old. In addition, 93 cases of the patients were tribes or lived in rural areas and 51 cases lived in urban areas. The highest frequency of the disease [44 cases] was seen in 27-41 year old group. The lowest frequency was seen in patients over 72 years old. The highest frequency [87 cases] belonged to housewives and the lowest frequency belonged to government employees. Most of the cysts [97 cysts] were in the right lobe of liver. Left lobe of the liver, right and left sides of the lung were the other locations respectively. Eight cysts were elsewhere. As many people in Charmahal va Bahktiari province live in tribes' style and also human, sheep and dogs are in a very close contact, more education programs are needed for people who are living in rural areas, especially housewives. In addition, infected dogs should be controlled and be treated in case of infection with Echinococus granulosus
