Percutaneous Cryoablation of Symptomatic Abdominal Scar Endometrioma: Initial Reports

Abstract

The purpose of this preliminary study was to report the short-term local control of percutaneous image-guided cryoablation of localized symptomatic abdominal scar endometrioma. Four consecutive patients (mean age 34.5 years) with a total of ten lesions were included, with mean preoperative pain of 7 (range 5-9) on the visual analog scale. Cryoablation was performed in a single session under general anesthesia. Postoperative superficial edema disappeared within 2 weeks for all patients. No severe complications (>grade 2 according to the CTCAE classification) were reported. Mean postoperative pain was 1.7 at 6 months (range 0-5) and magnetic resonance imaging demonstrated a significant volume decrease for all patients (range 72.2-100%; p = 0.028). Percutaneous cryoablation shows promising local control in patients with symptomatic abdominal wall endometriosis.
