Anal stenosis, a complication often following hemorrhoidectomy, can be anatomic or functional. Prevention through careful surgery and conservative management for mild cases are key, with surgical options for severe conditions.

Area of Science:

  • Colorectal surgery
  • Gastroenterology

Background:

  • Anal stenosis is a rare but serious complication of anorectal surgery.
  • Most commonly occurs after surgical hemorrhoidectomy, but can arise without prior surgery.

Purpose of the Study:

  • To review the etiology, classification, and diagnostic methods for anal stenosis.
  • To provide an overview of surgical and nonsurgical therapeutic options.

Main Methods:

  • Comprehensive review of current surgical literature.
  • Analysis of studies on anal stenosis causes, diagnosis, and treatments.

Main Results:

  • Anal stenosis can be anatomic (stricture) or functional (muscular).
  • Strictures are often preventable, typically resulting from overzealous hemorrhoidectomy.

  • Mild cases may be managed conservatively with dietary changes and stool softeners.

    • Conclusions:

    • A well-executed hemorrhoidectomy is the best preventative measure against anal stricture.
    • Gradual dilatation may be necessary for some patients.
    • Sphincterotomy and anoplasty are effective for moderate to severe symptomatic stenosis and stricture.
