retrospective analysis of echinococcosis in an endemic region of turkey, a review of 193 cases

background : the hydatidosis is endemic in our region. some of the recent studies revealed that hydatid cyst prevalence is decreasing gradually in turkey. the aim of this study was to investigate the actual preva­lence of hydatidosis in an endemic region of turkey, and to share our experiences in the medical and surgi­cal management of hydatidosis. methods : data were collected retrospectively from the records of 193 patients who had a diagnosis of hydatidosis, and admitted to diyarbakir education and research hospital. imaging techniques, histology and serology were used for diagnosis. results : from records of 772 cystic patients whose cysts were localized in the lung and liver, 193 (25%) of them were diagnosed with cyst hydatidosis. lung hydatidosis was found statistically significant among these cases (chi-square=24.88, p < 0.0001). postoperative recurrence was detected in seven (3.62%) pa­tients. all postoperative recurrences were observed in the consequent three years period. conclusion : the prevalence of hydatidosis is still high in southeast turkey and not only in children but also in adult cases in our region lung hydatidosis is frequent corresponding with other organ hydatidosis. we also found that the most risky period in recurrence rates is the consequent post-operative three years. according to our experiences, transthoracic approach in lung hydatidosis, external drainage, and cystec­tomy in liver hydatidosis is safe and effective choices in surgical treatment.
