  • Research summary

    Nerve entrapment as a cause of chronic abdominal pain is frequently overlooked. A series of nerves pass through the muscles of the abdomen before reaching the skin to carry sensations. They can get trapped within the muscles leading to severe pain resulting in a condition known as Abdominal Cutaneous Nerve Entrapment Syndrome (ACNES). ACNES affects between 10-30% of patients with chronic abdominal wall pain. A definitive diagnosis of ACNES is obtained by anaesthetising these nerves. Initial management includes education and avoidance of known triggers. It is common practice to inject steroid with local anaesthetic during the diagnostic injections itself to prolong pain relief. Like other nerve entrapment conditions, this is also refractory to medical treatment. Hence repeated injections and nerve entrapment release surgery are commonly carried out.

    In Aberdeen, a number of patients have been treated for this condition. A cohort of patients have benefitted with injection alone while recurrence has been noted in patients who have undergone surgery. This project aims to gain more understanding about the clinical course of patients with suspected ACNES.
