Background: Anal fissure is a benign yet highly prevalent condition that can cause considerable pain and discomfort. It is a longitudinal Split or tear of the anal canal extending proximally from the anal verge towards the dentate line. Objectives: To compares the open and closed techniques of lateral internal sphincterotomy and study which method is better among open vs closed lateral sphincterotomy. Material & Methods: Patients admitted in Bowring and Lady Curzon hospital and Victoria hospital attached to Bangalore Medical College and Research Institute from November 2015 to May 2017 were studied (n=60). Thirty patients underwent closed and thirty underwent open lateral internal sphincterotomy out of 60 after informed written consent. Results: Post operative pain after 48, 60, 72 and 96 hours was less in closed group along with seroma, hematoma and abscess. Conclusion: we observed that closed lateral internal anal sphincterotomy is better than open technique.
