The background and purpose of the study: Anal fissure is a common benign anal condition, the gold standard treatment is Lateral Internal Sphincterotomy (LIS), and this procedure carries a risk of incontinence. The aim of this study is to determine the long-term risk of sphincter dysfunction after LIS using a questionnaire. Method: All patients who had LIS for chronic anal fissure between the years 2004 till 2010 were interviewed by phone and assessment of Sphincter function (incontinence) using Wexner Fecal Incontinence Score (WIS). Results: 59 patients (34 females, 57.6%) with a mean follow-up duration of 10.6 years (range 8 to 15 years) were interviewed. Twelve patients (20.3 %) had WIS score of one or more. The majority of the patient noticed the change in sphincter function years after the operation. Conclusion: This long-term risk of abnormal sphincter function after LIS could be higher than expected especially in the presence of multiple vaginal deliveries or systemic diseases such as Diabetes mellitus. Larger prospective studies are required before LIF is offered routinely to these patients.
