Injection of absolute alcohol into cysts cavities, after cyst aspiration, for treating and reducing the rate of recurrence of benign breast cysts

摘要

The purpose of this study is to determine whether injection of absolute alcohol into cysts cavities, after cyst aspiration, is useful to treat benign breast cysts (BBCs) and to reduce its rate of recurrence. Fifteen women with recurrent BBC were enrolled in a 3.5?years follow-up study. Cyst aspiration and replacement by an equal volume of absolute alcohol (99%) within cysts cavities was performed under guidance of ultrasonography. BBC was defined as a breast cyst without cytologic changes for malignancy. Ultrasonographic breast images and breast biopsies were performed to verify cyst resolution and recurrence. Breast cysts completely disappeared in six (40%) women and significantly decreased its average size (67?±?38 to 5.2?±?6.8?mm, p =?0.002) in eight (53.3%) women. At the end of the follow-up (42.1?±?13.3?months) study, 14 women (93.3%; 14/15) were free of recurrence; one (6.7%) woman did not show variation (54?mm) in the size of BBC. Alcohol sclerotherapy can then be considered as a useful alternative option in the treatment of recurrent BBC.
