Colonic motility is abnormal before surgery for rectal prolapse.

Summary

Patients with rectal prolapse exhibit abnormal hindgut motility before surgery. This motility disorder may explain poor functional outcomes after abdominal rectopexy and suggests colonic resection as a potential treatment.

Area of Science:

  • Gastroenterology
  • Colorectal Surgery
  • Neurogastroenterology

Background:

  • Abdominal rectopexy is the standard surgical treatment for rectal prolapse.
  • While recurrence rates are low, functional outcomes post-surgery are often suboptimal.
  • The underlying cause for poor functional results after rectopexy requires further investigation.

Purpose of the Study:

  • To investigate hindgut motility in patients with rectal prolapse before surgical intervention.
  • To determine if an underlying neuropathy contributes to poor functional results after abdominal rectopexy.
  • To explore potential therapeutic targets for improving outcomes in rectal prolapse patients.

Main Methods:

  • Colonic intraluminal pressure was recorded using a multilumen catheter in seven women with rectal prolapse.

  • Motility patterns, including high-amplitude propagated contractions (HAPCs), were measured before and after meals.
  • Data were compared to motility measurements from five healthy controls.

    • Main Results:

    • Patients with rectal prolapse demonstrated high baseline colonic motility and contraction frequency, even before meals.
    • Unlike controls, patients did not show increased motility in response to meals.
    • High-amplitude propagated contractions (HAPCs) were significantly reduced in patients compared to controls.

    Conclusions:

    • Patients with rectal prolapse present with a distinct hindgut motility abnormality prior to abdominal rectopexy.
    • This motility dysfunction resembles that seen in spinal cord injury patients.
    • The findings suggest a potential rationale for considering colonic resection in addition to rectopexy to address functional deficits.
