Delorme's procedure for rectal prolapse improved rectal sensation and lowered rectal compliance in older women. These changes were linked to fewer defecation problems after surgery.

Area of Science:

  • Colorectal surgery
  • Pelvic floor disorders

Background:

  • Full-thickness rectal prolapse affects many older adults.
  • Defecation difficulties are common post-treatment for rectal prolapse.

Purpose of the Study:

  • To evaluate the impact of Delorme's procedure on anal sphincter pressures, rectal compliance, and rectal sensation.
  • To determine the relationship between these physiological changes and postoperative defecation outcomes.

Main Methods:

  • Prospective study of 19 women (mean age 77 years) undergoing Delorme's procedure.
  • Assessment of anal sphincter pressures, rectal compliance, and rectal sensation before and after surgery.

Main Results:

  • No significant changes in anal sphincter pressures were observed.

  • A significant decrease in the volume of first rectal sensation (140 ml to 65 ml) and maximum tolerated rectal volume (249 ml to 120 ml) was noted.
  • Rectal compliance significantly decreased from 142.9 ml/kPa to 12.2 ml/kPa.

    • Conclusions:

    • Delorme's procedure leads to improved rectal sensation and reduced rectal compliance.
    • These physiological modifications are associated with a lower incidence of defecation problems following surgery for rectal prolapse.
