sphincterotomy in the treatment of chronic anal fissure. Setting: Department of Surgery, Nishtar Hospital Multan
Period: From April 2002 to September 2002. Material and Methods: The study subject included 50 patients. Twenty

sphincterotomy (OLIS). Follow-up for complications was done for the period of 4 months after the procedure. Results:
The best results were obtained with closed lateral internal sphincterotomy in which incontinence rate was 24% and
recurrence rate 12%. Conclusion: Closed lateral internal sphincterotomy is treatment of choice for chronic anal fissure
with acceptable complication rate.
