ABSTRACT
OBJECTIVE:
To retrospectively evaluate the long-term outcomes after percutaneous cryoablation of abdominal wall endometriosis (AWE).METHOD:
The Institutional Review Board approved this retrospective observational review of 40 consecutive patients, of a median age of 37 years (interquartile range [IQR] 32-40 years), presenting with a total of 52 symptomatic AWE nodules. All patients underwent cryoablation between January 2013 and May 2022 with a minimum follow-up period of 12 months. Outcomes were assessed using a visual analog scale (VAS) that measured pain, as well as by magnetic resonance imaging (MRI). The pain-free survival rates were derived using the Kaplan-Meier estimator. Adverse events were analyzed and graded using the classification system of the Cardiovascular and Interventional Radiological Society of Europe.RESULTS:
The median follow-up time was 40.5 months (IQR 26.5-47.2 months). The median VAS score before cryoablation was 8 (IQR 7-9). Complete relief of symptoms was documented in 80% (32/40) of patients at 3 months after initial cryoablation and correlated with the absence of residual endometriosis nodules on MRI. The median pain-free survival rates were 89.2% [95% CI, 70.1-96.4%] at 36 months and 76.8% [95% CI, 55.3-83.8%] after 60 months. No patient or lesion characteristics were found to be prognostic of failure. No major adverse events or side effects were reported in long term.CONCLUSION:
Cryoablation safely and effectively afforded long-term pain relief for patients with AWE nodules. CLINICAL RELEVANCE STATEMENT AWE cryoablation was found to be safe and effective in the long-term. KEY POINTS ⢠Cryoablation is highly effective with 80% of patients experiencing complete relief of AWE symptoms after a single procedure. ⢠Cryoablation is safe without long-term adverse events or side effects. ⢠The median pain-free survival rates are 89.2% at 36 months and 76.8% at 60 months.
