Background: In this clinical retrospective study, we aimed to investigate our experinces and whether capitonnage is an effective therapy method for a pulmonary hydatid cyst or not. Material and methods: A total of 412 patients with hydatid cyst operated in our hospitals were evaluated retrospectively between January 2003 and January 2011. In order to create a study group to compare the hydatid cyst operations with and without capitonnage in our department, 60 uncomplicated patients with the diagnosis of hydatid cyst who had undergone operations in the previous two years, were divided into two groups; while no capitonnage was performed and bronchial leaks were closed in one group, standard cystotomy plus the capitonnage operation was performed in the second group. All patients underwent surgery. Results: In many patients, one or more symptoms were present on admission (339 cases, 82%). Perforated cysts/nonperfore cysts rate was statistically significant (p = 0.001). There was no statistical difference between patients with or without capitonnage in terms of morbidity rates between patients with or without capitonnage (p = 0.041). However, morbidity rates were higher in the group without capitonnage. There were found statistically significant between capitonnage and non capitonnage groups in terms of length of hospital stay (p = 0.001). Conclusions: In the surgical treatment, resection should be avoided as much as possible. An average time of 3-5 minutes should be allocated and capitonnage should be performed. Capitonnage should always be performed in the surgical treatment of hydatid cyst. We believe that povidone iodine per se provides sufficient disinfection.
