Posterior sagittal anorectoplasty (PSARP) offers improved outcomes for anorectal malformations by enabling direct visualization and maximal use of continence muscles. Bowel management programs and biofeedback may further enhance fecal continence in challenging cases.

Area of Science:

  • Pediatric Surgery
  • Congenital Anomalies
  • Gastroenterology

Background:

  • Anorectal malformation (ARM) is a common congenital anomaly requiring complex surgical correction.
  • Historically, various anoplasty techniques were used, with varying success rates.
  • The posterior sagittal approach has become a standard for ARM correction.

Purpose of the Study:

  • To review the evolution of surgical techniques for anorectal malformations.
  • To evaluate the efficacy of posterior sagittal anorectoplasty (PSARP) in treating the spectrum of ARM.
  • To discuss adjunctive therapies for improving fecal continence.

Main Methods:

  • Retrospective review of approximately 400 ARM cases treated between 1977 and 1997.
  • Exclusive adoption of PSARP for ARM correction since 1985.

Related Experiment Videos

  • Analysis of outcomes in 200 patients who underwent PSARP (166 primary, 34 secondary).

    • Main Results:

    • PSARP allows direct visualization and optimal utilization of continence muscles, leading to better fecal continence.
    • The procedure accommodates the entire spectrum of ARM defects with improved cosmesis and fewer immediate postoperative complications.
    • Despite PSARP, 10-30% of patients experience intractable fecal incontinence.

    Conclusions:

    • PSARP is an effective procedure for correcting anorectal malformations, offering improved functional and cosmetic results.
    • Bowel management programs and biofeedback therapy are crucial for managing persistent fecal incontinence.
    • A new concept of fecal continence mechanism and surgical construction is proposed for ARM treatment.
