Abdominal Cutaneous Nerve Entrapment Syndrome (ACNES)
摘要
Chronic abdominal wall pain (CAWP) is a common presentation with a prevalence of 1 in 1800 in the general population. Of those with CAWP, 10–30% have been associated with abdominal cutaneous nerve entrapment syndrome (ACNES, also known as anterior cutaneous nerve entrapment syndrome) (Kanakarajan et al., Br J Pain. 16:538–545, 2022). ACNES manifests due to entrapment of the anterior cutaneous branch of the lower thoracoabdominal intercostal nerves and subcostal nerve (T7–T12) within the rectus abdominis muscle or its sheath. Patients commonly experience paresthesias and/or severe, localized pain and tenderness in this nerve distribution, most often at the ventral portion of the abdomen.
