- Abstract
Purpose: Patients with anterior cutaneous nerve entrapment syndrome (ACNES) often require a step‐up treatment strategy including abdominal wall injections, pulsed radiofrequency (PRF) or a neurectomy. Long‐term success rates of PRF and surgery are largely unknown. The aim of the current study was to report on the long‐term efficacy of PRF and neurectomy in ACNES patients who earlier participated in the randomized controlled PULSE trial. Methods: Patients who completed the PULSE trial were contacted about pain status and additional treatments in the following years. Treatment success was based on numerical rating scale (NRS) following IMMPACT recommendations and Patient Global Impression of Change (PGIC) scores. Results: A total of 44 of the original 60 patients were eligible for analysis (73.3%). Median follow‐up was 71.5 months. One patient (4.3%) was still free of pain after a single PRF session, and five additional patients (21.7%) were free of pain by repetitive PRF treatments. By contrast, 13 patients (61.9%) in the neurectomy group were still free of pain without additional treatments. All pain recurrences and therefore primary re‐interventions occurred in the first 2 years after the initial treatment. Conclusion: Approximately one in five ACNES patients undergoing PRF treatment reports long‐term success obviating the need of surgical intervention. Surgery for ACNES is long‐term effective in approximately two of three operated patients. Recurrent ACNES beyond 2 years after either intervention is rare.
