Seventy-six patients treated at York Pain Relief Clinic for Abdominal Nerve Entrapment Syndrome (ANES) between 1982 and 1986, using aqueous phenol and nerve stimulator control are reviewed. A questionnaire was sent to all the patients who had been discharged from the clinic to try to confirm that the initial improvements had been maintained and 60 patients replied. Group A (n = 44) had been diagnosed with confidence; 95% had gained complete or partial relief of symptoms. Group B (n = 32) had other symptoms making the diagnosis less certain; 50% gained some relief. Clinical presentation of ANES and the method of treatment are described.
