Midline abdominal wall surgery, such as a laparotomy or cesarean section, can sometimes lead to anterior cutaneous nerve entrapment (ACNES) and subsequent pain. This occurs through various direct and indirect mechanisms:
Direct Mechanisms:
- Nerve Injury: During surgery, the nerves supplying the abdominal wall can be directly injured by the incision itself, surgical instruments, or cauterization. This injury can lead to nerve damage and dysfunction, resulting in pain, numbness, and tingling.
- Scar Tissue Formation: The healing process after surgery can lead to the formation of scar tissue around the nerves. This scar tissue can compress and trap the nerves, causing pain and interfering with their function.
- Nerve Stretching: During surgery, the abdominal wall is stretched and manipulated, which can stretch the nerves and potentially damage them. This can lead to pain and other neurological symptoms.
Indirect Mechanisms:
- Muscle Imbalance: Surgery can weaken the abdominal muscles, leading to imbalances in muscle strength and tension. This can place additional stress on the nerves and contribute to pain.
- Inflammation: The surgical procedure itself can cause inflammation in the surrounding tissues, which can irritate the nerves and contribute to pain and discomfort.
- Changes in Sensation: The surgical incision can interrupt the normal sensory pathways in the abdomen, leading to altered sensations such as numbness, tingling, and hypersensitivity. This can contribute to pain and discomfort.

It’s important to note that not everyone who undergoes midline abdominal wall surgery will develop ACNES. The risk of developing ACNES depends on various factors, including the type of surgery, the skill of the surgeon, and the individual’s healing process.
If you are experiencing pain or other symptoms suggestive of ACNES after abdominal wall surgery, it’s crucial to consult your doctor for diagnosis and appropriate treatment.
