P-THER-09: Endoscopic ultrasound-guided pelvic abscess drainage

Endoscopic ultrasound (EUS)-guided pelvic abscess drainage though uncommon modality for definite treatment of pelvic abscess is an effective method of treatment for pelvic abscess due to its proximity to rectal wall. We performed drainage of pelvic abscess in a 65-year-old male with uncontrolled diabetes, abscess was measured 78 mm × 77 mm, drainage was performed using two 10 Fr pigtail stents, spontaneous drainage of entire abscess cavity was noted, and the patient was discharged on the same day on oral antibiotics with dramatic improvement in pain, fever, and total leukocyte count. EUS drainage has an advantage of being a day-care procedure; as compared to percutaneous drainage, no discomfort of external catheter and limited mobility are experienced by the patient. Other modalities such as conventional ultrasonography-guided per rectal/vaginal drainage have disadvantage that stent cannot be placed.
