All these patients were with symptomatic, anal fissure, with failed medical treatment and long history. All these patients were operated under spinal and general anesthesia in lithotomy position. Digital examination and proctoscopic examination was done. Among 100 patients 56 patients (56%) were free of pain within 24 hours and 42 patients (42%) had no pain after 48 hours. Two patients (2%) complained of persistent moderate to severe pain. Among 100 patients 6 patients (6%) had haemorrhage with soakage of gauze piece but there was no active bleeding.
