Image-guided drainage management of tubo-ovarian abscess and the role of C-reactive protein measurements in monitoring treatment response: a single-center experience.

Image-guided drainage combined with antibiotherapy in the treatment of TOA has high success rates, lower recurrence rates, and lower surgical requirement, and the mean decrease in the CRP level on day 4 can be monitored at treatment follow-up. In patients receiving antibiotherapy alone, if the CRP level on day 4 decreases by < 37.1%, the treatment protocol should be changed.
