BACKGROUND: Currently, the lateral internal sphincterotomy is the treatment of choice for a chronic anal fissure. However, the length of the internal sphincter incision varies, due to lack of standardization. Insufficient length increases the risk of recurrence. OBJECTIVE: To compare a new ultra-modified internal sphincterotomy technique to the closed lateral sphincterotomy for treating chronic anal fissures, based on internal anal sphincter function and postoperative complications. DESIGN: Prospective, randomized, controlled trial (block randomization method) SETTING: Pamukkale University hospital in Denizli-Turkey PARTICIPANTS: 200 patients with chronic anal fissures INTERVENTION: Patients were randomly assigned to receive either Sungurtekin technique (n = 100; ultra-modified group), or the closed lateral internal sphincterotomy (n = 100; closed-lateral group). Follow-up was 2 years. MAIN OUTCOME MEASURES: The primary outcome was chronic anal fissure healing. The secondary outcomes were complications, visual analog scale pain scores, sphincter pressures, and incontinence scores.
