Anal stenosis in the elderly: dilation or surgical repair

What is known

• Mild anorectal stenosis is managed conservatively (fiber, stool softeners, self-dilation); moderate-to-severe stenosis is treated by sphincterotomy, anoplasty, or advancement flap. ¹
• Short tight strictures can be dilated even under anesthesia, but long strictures or those with fistulas or a severely diseased rectum may require proctectomy. ²
• In reported small series dilation results varied widely, from durable relief to all patients failing and requiring proctectomy, with incontinence in some. ²
• Endoscopic balloon dilation for Crohn's strictures is contraindicated with associated fistula, abscess, or deep ulceration owing to perforation risk. ^3,4

What is unknown / caveats

• Dilation outcomes range from durable relief to universal failure requiring proctectomy across the small case series ^2,5
• Retrieved data on anal stenosis are old, small case series (Bernard, Keighley, Linares), no comparative or elderly-specific outcomes
• Much of the EBD evidence concerns luminal/anastomotic strictures, not the anal canal specifically
• No retrieved study compares balloon dilation with surgical excision and primary repair for anal stenosis, and none stratifies by age or comorbidity.
