Sonographically guided aspiration: an alternative therapy for tubo-ovarian abscess.

Our objective was to evaluate the role of single-step ultrasound-guided aspiration in conjunction with intracavitary antibiotic instillation for the treatment of tubo-ovarian abscess. Ten women with the clinical and sonographic diagnosis of tubo-ovarian abscess, who failed to respond to systemic antibiotic therapy, were treated by ultrasound-guided aspiration of the abscess followed by intracavitary instillation of a combination of antibiotics. All ten women improved clinically and none required surgery. The mean time from aspiration to hospital discharge was 3.1 days with mean duration of hospitalization 7.8 days. No major complications were observed. The average time interval between aspiration of the lesion and resolution on sonographic follow-up was 9.5 weeks. In three cases, pelvic inflammatory disease recurred, but none needed surgical intervention. The average follow-up period of the patients was 12 months. One-step sonographically guided aspiration of tubo-ovarian abscess followed by intracavitary antibiotic instillation may serve as an easy and safe alternative therapy in patients in whom treatment with systemic antibiotics has failed.
