BackgroundThe aim of the study was to introduce a new surgical treatment for anterior cutaneous nerve entrapment syndrome, a frequently unrecognised disorder in the general population responsible for chronic abdominal wall pain with limited treatment options to date. We hypothesised that intraperitoneal onlay mesh reinforcement could dissipate excessive increases in intra-abdominal pressure and prevent entrapment of the neurovascular bundle.MethodsRetrospective cohort analysis was performed between September 2002 and March 2014. All consecutive patients diagnosed with anterior cutaneous nerve entrapment syndrome refractory to conservative treatment (n = 30) underwent laparoscopic intraperitoneal onlay mesh reinforcement of the painful area in the abdominal wall. Planned follow-up took place at 2, 6 and 12 weeks after surgery and at time of analysis (March 2015). Primary outcome was patients' satisfaction after treatment at short and long term (last follow-up) using a verbal rating score as measurement (1 = I am very satisfied; I never experience pain, 2 = I am satisfied; I occasionally experience some pain, 3 = I have improved but experience pain on a regular basis, 4 = I have had no result on this treatment, 5 = my pain is worse after treatment). Scores 1 and 2 were classified as success, and scores 4 and 5 as failure of the treatment.ResultsThirty patients underwent laparoscopic intraperitoneal onlay mesh reinforcement. None were lost to follow-up (mean 54 ± 44 months, range 12-122, median 38). Short- and long-term success rates were 90 and 71 %, respectfully.ConclusionsIntraperitoneal onlay mesh reinforcement of the abdominal wall seems to be a promising option for the treatment of intractable anterior cutaneous nerve entrapment syndrome.
