Cryoablation Reduces Umbilical Endometriosis Pain and Volume in Outpatient Study

Extrapelvic endometriosis remains a complex clinical entity, often presenting as painful nodules within the abdominal wall or surgical scars [1, 2]. While frequently associated with prior obstetric or gynecological procedures, primary cases can occur in the absence of surgical history, which complicates the initial differential diagnosis [3, 4]. Patients typically present with cyclic pain and palpable masses, necessitating high clinical awareness and a multidisciplinary approach to ensure accurate diagnosis [5, 4]. Traditional management has relied heavily on surgical excision, which carries risks of tissue damage and cosmetic dissatisfaction, particularly when lesions are embedded within the rectus abdominis muscle [3, 2]. A recent study evaluates percutaneous image-guided cryoablation, a minimally invasive technique using extreme cold to destroy ectopic tissue under ultrasound or computed tomography guidance, as an alternative to standard surgical approaches [6]. In a cohort of 17 women, this technique achieved complete pain relief in 82% of patients and a 73% median reduction in nodule volume (p < 0.001) at a 22-month median follow-up [6].
