About This Treatment
Fistulotomy involves surgically opening the entire fistula tract by cutting along its length, converting the "tunnel" into an open groove that heals from the inside out. Fistulectomy involves complete excision (removal) of the fistula tract along with a small margin of surrounding tissue.
These are the most time-tested surgical options for simple, intersphincteric (low) fistulas where the tract runs below or through the lower portion of the sphincter. The procedures offer the highest cure rate (95%+) for eligible fistulas.
Patient selection is crucial — fistulotomy carries some risk of incontinence if too much sphincter muscle is divided. Our surgeons carefully assess each fistula with MRI to determine whether the fistula is suitable for fistulotomy or whether sphincter-preserving alternatives (like Ksharsutra or FiLaC) are preferable.
