Background: Pelvic abscess is a common complication of abdominal surgery or intestinal or gynecological diseases. Over the last decades, endoscopic ultrasound (EUS)-guided drainage has emerged as a minimally invasive alternative to percutaneous or surgical treatment of pelvic abscesses.

Aim: To evaluate safety and efficacy of EUS-guided transrectal pelvic abscess drainage in a single center.

Methods: From February 2017 to April 2023, all data on patients who were treated for pelvic abscesses by EUS-guided drainage in a single center, were retrospectively analyzed.

Results: A total of 17 patients were treated for pelvic abscesses by EUS-guided drainage. The procedure was technically successful and uneventful in all 17 patients (100%). Etiology of the abscess was postsurgical (n=5, 29%), secondary to medical illness (n=10, 59%) or gastrointestinal perforation (n=2, 12%). The abscess was multilocular in 5 patients (29%), the mean largest diameter was 76 mm (range 40-146 mm). Drainage was performed using 2 double pigtail stents, and in 1 patient an additional 10 Fr drainage catheter was deployed. Two patients (12%) required a second endoscopic intervention. Treatment success, defined by complete abscess resolution on follow-up CT scan along with symptom relief, was 100%. There was no need for surgical intervention. The median post-procedural hospital stay was 5 days. No recurrence was reported within a median time of follow-up of 39 months.

Conclusion: EUS-guided transrectal drainage of pelvic abscesses using double pigtail stents is safe and highly effective. This case series contributes to the cumulative evidence that, in expert hands, EUS-guided drainage should be considered as first-line approach for treatment of pelvic abscesses.
