Abstract
The role of interventional radiology in treatment of pelvic abscesses and collections is increasing recently, helping to reduce morbidity and mortality of surgery and may eliminate the need for surgery in the near future.
Although many imaging modalities are used for guidance, the increasing value of ultrasound has been realized for those collections and abscesses at difficult locations.
Aspiration guided by ultrasound is minimally invasive, well tolerated and also applicable in patients who are at risk for anesthesia or operation.
Transabdominal as well as transvaginal routes have been reported to be reliable and effective minimally invasive treatment options.
Our study included 30 female patients divided on clinical and radiological basis into 4 groups; simple cysts, complicated cysts, tubo-ovarian abscess and post-operative collection. Preliminary diagnosis was done by pelvic ultrasound to be confirmed by CT and/or MRI.
Regarding patients with ovarian cysts, we excluded all cases with suspected malignancy or endometriosis. Only the cysts with benign criteria were included.
All patients with simple cysts were treated by simple ultrasound guided aspiration through long Chiba needle with no need for pig tail catheter insertion. The technique was successful in 66.6 % of patients with simple cysts in one cession. In 26.6% of patients with simple cysts, additional cession(s) were needed. In only 6% of cases (one patient), the procedure failed to achieve complete cure necessating surgery.
All patients with complicated cysts were treated by ultrasound guided pig tail catheter drainage whether through transvaginal or transabdominal routes. The catheter was left in place for two weeks and complete drainage was achieved with no complications recorded.
Regarding patients with tubo-ovarian abscesses and post-operative collections, both simple aspiration and pig-tail catheter drainage were used accordingly. Complete drainage was achieved in all patients.
No significant complications were encountered during any of the previous procedures. Overall, the procedure was safe, well-tolerated and usually performed on an outpatient basis.
