• 'Simple' anal fistulas include subcutaneous, intersphincteric or low transsphincteric fistulas with minimal involvement of the sphincter complex.
• Commonly used definitions of simple anal fistulas are intersphincteric or low transsphincteric fistulas that involve less than 30% of the EAS and do not have any features of complexity.
• Fistulotomy should be used in patients with intersphincteric or low transsphincteric anal fistula and normal preoperative continence, following a thorough assessment of fistula anatomy, symptomatology, involvement of sphincters, risk of incontinence and exploration of patient expectations.
• Marsupialization could be performed following fistulotomy and fistulectomy for simple anal fistula.
• Fistulotomy is thought to be the gold-standard treatment for simple anal fistula as it is associated with a high rate of fistula healing without diminishing continence.
