Comparative study of Glyceryl Trinitrate ointment versus lateral internal sphincterotomy in management of Chronic anal fissure.
Objectives: To compare efficacy of topical 0.2% glyceryl trinitrate ointment with lateral internal sphincterotomy in treatment of patients with chronic anal fissure.

Material & Methods: A total number of 60 patients included in this study and divided into two groups GTN and LIS group through computer generated randomization method. Three main outcome variables were assessed in this study; pain relief, healing of fissure and recurrence. SPSS version was used to analyze data. P value ≤ 0.05 was considered as significant. Results: A total number of 60 patients included in this study. Relief of pain GTN and LIS was (95%) and (86.7%) respectively. Fissure healing GTN and LIS was noted as (88.3%) and (83.3%) respectively. Recurrence was not found in any patient of the present study. Relief of pain was statistically significant.
