Combined transrectal sonographic and fluoroscopic guidance for deep pelvic abscess drainage

We attempted to determine the feasibility, safety, and success of transrectal catheter drainage of deep pelvic abscesses using a combination of transrectal sonography and fluoroscopic guidance. In this retrospective review of five cases, transrectal catheters were placed within abscess cavities over a 20 month period. Clinical improvement was prompt, catheters were removed within 7 days, and no complications were detected. No patient required further intervention (follow-up 2 to 20 months). Transrectal sonographically guided catheter drainage proved to be safe and effective in our series. This method is a promising alternative to the posterior (sciatic notch) approach when the anterior transabdominal approach is contraindicated.
