PERCUTANEOUS DRAINAGE OF TUBOOVARIAN ABSCESSES

The authors performed percutaneous drainage of 27 tubo-ovarian abscesses (TOAs) in 16 patients in whom medical therapy with triple antibiotics prior to catheter drainage had not been successful. Percutaneous drainage was successful in 15 of 16 patients (94%). One patient underwent total abdominal hysterectomy and bilateral salpingo-oophorectomy 3 days after catheter placement because of persistent symptoms and lack of drainage from the catheter; at laparotomy, a large infected phlegmon was found. Two patients had recurrent disease at 3 and 4 months after catheter placement. Bilateral salpingectomy was performed in one patient and total abdominal hysterectomy and bilateral salpingo-oophorectomy in the other. One of these patients had cervical carcinoma, and the other had a long history of recurrent pelvic inflammatory disease and TOAs. The long-term avoidance of surgery was 81.2%. Access routes for catheter drainage were through the anterior abdominal wall for 10 abscesses, through the posterior transgluteal route for 11, and through the transvaginal route for six. Duration of drainage was 1-20 days (mean, 6 days). Complications consisted of transient sciatic pain in two patients and mild bacteremia in one. The results indicate that percutaneous drainage of TOAs is effective in patients in whom medical therapy is not successful.
