Anterior Cutaneous Nerve Entrapment Syndrome (ACNES) is caused by entrapment of end branches of intercostal nerves that are residing in the abdominal wall. Patients suffer from severe abdominal pain that is often not recognized as most doctors are focused, when confronted with abdominal pain, on a visceral source of the pain. If ACNES is diagnosed, treatment includes sub-fascial injections of an local anesthetic (whether or not combined with an long acting corticosteroid). If pain is recurrent, the entrapped nerve is surgically removed. A neurectomy procedure is effective in approximately 70% of patients after one year.

Primaire uitkomstmaten
Primary objective is to evaluate the effect of PRF treatment in comparison with neurectomy in
terms of pain relief at 8 weeks follow up. This outcome will be measured using Numeric Pain
Rating Scale 0-10 (0 = no pain and 10 = excruciating). Primary outcome will be the
percentage of decrease on the NPRS scale.
Doel van het onderzoek
Primary objective is to evaluate the effect of PRF treatment in comparison with neurectomy in
terms of pain relief. This outcome will be measured using Numeric Pain Rating Scale 0-10 (0
= no pain and 10 = excruciating).
Hypothesis:
PRF as treatment for ACNES is equally effective (or better) than neurectomy

Onderzoeksproduct en/of interventie
Subjects will be randomized to either arm of treatment, one arm being PRF and the other arm
neurectomy treatment. Subjects will be followed for 12 months after receiving the procedure.
At the 8 weeks follow up visit, the PRF group will be given the option to cross over to the
alternate arm of the trial. All patients who do not cross over will be prospectively followed to
12 months evaluation time point.
