Objective. For treatment of suspected pelvic abscesses, the use of the trocar technique avoids many of the technical challenges of the Seldinger method. The purpose of this study was to evaluate the effectiveness and safety of sonographically guided transvaginal aspiration or drainage with the trocar technique in suspected pelvic abscesses that were refractory to antibiotic treatment. Methods. We retrospectively reviewed 22 patients with suspected pelvic abscesses refractory to antibiotic therapy who underwent single-step transvaginal pelvic aspiration or drainage between 1995 and 2000. Results. Transvaginal aspiration or drainage was successful in 19 (86%) of the 22 patients. Of the 3 patients in whom aspiration or drainage failed, all ultimately went on to have surgery despite undergoing repeated drainage procedures. Drainage catheters were placed in 15 (68%) of the 22 patients and left in place an average of 3.7 days. Aspiration alone resulted in a 100% success rate, whereas drainage with catheter placement resulted in an 80% success rate. No complications, including bleeding, bowel perforation, and death, were reported in any of the procedures. Conclusions. Transvaginal ultrasonographically guided aspiration or catheter placement with the trocar technique is a safe and effective treatment for suspected pelvic abscesses refractory to antibiotic therapy.
