Stricture of anal canal

Last edited: 4/23/2026

Overview

Anal canal stricture is a narrowing of the anal canal leading to functional obstruction, often resulting from previous surgical interventions such as hemorrhoidectomy, fistulectomy, or fissurectomy. Conservative treatments frequently fail, necessitating surgical interventions for resolution 1.

Diagnosis

  • History of prior anal surgeries (hemorrhoidectomy, fistulectomy, fissurectomy)
  • Persistent symptoms despite conservative management (e.g., pain, constipation, incontinence)
  • Physical examination revealing anal canal narrowing
  • Imaging (e.g., anoscopy, MRI) to assess stricture extent and etiology 1

    • Management

  • First-line treatments: Conservative management (dietary modifications, stool softeners, topical treatments) often ineffective over prolonged periods 1
  • Surgical interventions: C-anoplasty recommended for refractory cases; extends pedicle without compromising vascular supply, adjusts suture tension, and tailors graft size to anal dimensions 1
  • Postoperative care: Anal dilatations may be required to prevent restricture 1

    • Special Populations

  • No specific data provided for pregnancy, pediatrics, elderly, or comorbidities in the given abstracts 1

    • Key Recommendations

  • Consider C-anoplasty for patients with refractory anal stricture unresponsive to conservative treatments for extended periods (Evidence: Weak) 1
  • Postoperative anal dilatations should be considered to prevent recurrence of stricture following surgical intervention (Evidence: Weak) 1
  • Prior surgical history, particularly hemorrhoidectomy, fistulectomy, or fissurectomy, is a significant risk factor for developing anal stricture (Evidence: Expert opinion) 1
