Postoperative biofeedback significantly improved fecal incontinence outcomes in patients following sphincteroplasty for obstetric sphincter injuries. This therapy offers a valuable option for those with suboptimal results after initial surgical repair.

Area of Science:

  • Obstetrics and Gynecology
  • Colorectal Surgery
  • Pelvic Floor Rehabilitation

Background:

  • Overlapping sphincteroplasty is the primary surgical treatment for obstetric sphincter injuries.
  • Despite anatomical restoration, 35% of patients experience persistent fecal incontinence post-surgery.

Purpose of the Study:

  • To evaluate the efficacy of postoperative biofeedback in improving continence in patients with poor functional outcomes after sphincteroplasty.
  • To assess the impact of electromyographic biofeedback on incontinence scores and episodes.

Main Methods:

  • A review of 28 patients who underwent electromyographic biofeedback training post-sphincteroplasty for obstetric sphincter injury.
  • Patients completed incontinence questionnaires and bowel diaries before and after biofeedback treatment.

  • Incontinence severity was scored using a scale up to 30, with weekly incontinent episodes recorded.

    • Main Results:

    • Average incontinence scores significantly decreased from 20 to 3 (P < 0.0001).
    • Weekly incontinent episodes reduced from 5.4 to 1.4 (P < 0.0001).
    • 89% of patients reported improved continence, with posttreatment scores below 3.

    Conclusions:

    • Postoperative biofeedback therapy enhances functional outcomes for patients experiencing suboptimal results after sphincteroplasty.
    • Biofeedback represents a viable and effective non-surgical option for managing persistent fecal incontinence post-obstetric sphincter injury repair.
