    Area of Science:

    • Pain management
    • Surgical outcomes
    • Regenerative medicine

    Background:

    • Post-surgical pain can significantly impact patient recovery and quality of life.
    • Trigger points in operative scars are a recognized, yet often challenging, source of chronic pain.
    • Conservative treatments for scar pain have variable efficacy, necessitating further therapeutic options.

    Purpose of the Study:

    • To evaluate the efficacy of alcohol injections for treating painful trigger points in operative scars.
    • To determine the safety and effectiveness of this minimally invasive procedure.
    • To assess the long-term outcomes of alcohol ablation for scar-related pain.

    Main Methods:

    • Sixty-nine patients with painful operative scar trigger points were included, excluding specific surgical histories and psychological factors.

  • Diagnosis involved identifying consistent, tender trigger points providing transient pain relief upon bupivacaine injection.
  • Treatment consisted of repeated alcohol injections into the identified trigger points.

    • Main Results:

    • A high success rate was observed, with 63 out of 69 patients (91%) experiencing permanent cure or marked improvement.
    • The alcohol injection treatment was found to be simple and safe, with no significant adverse events reported.
    • Transient pain relief with bupivacaine confirmed trigger point diagnosis, preceding the effective alcohol ablation.

    Conclusions:

    • Alcohol injection into operative scar trigger points is a highly effective, safe, and simple treatment modality.
    • This method offers a promising solution for managing chronic post-surgical pain originating from scar tissue.
    • Further research could explore long-term efficacy and patient-reported outcomes in larger cohorts.
