Abstract
Background: Chronic anal fissure as a common anorectal disorder with excruciating pain and bleeding on passage of stools. The treatments of choice are universally conservative, as well as surgical interventions.
Objectives: This research aimed to compare the efficacy of glyceryl trinitrate (GTN) ointment and lateral sphincterotomy in treating chronic anal fissure.
Study Design: A Prospective Study.
Duration and Place of the Study: This study was conducted at the Department of General Surgery, Combined Military Hospital, Peshawar, Pakistan over a period of Six Months from 01st January 2023 to 30th, June 2023.
Material and Methods: This is a prospective randomized trial including 2 groups of treatments for 68 patients diagnosed as having chronic anal fissure. GTN group (n=34): topical glyceryl trinitrate 0.2% ointment twice daily Lateral sphincterotomy group (n=34): lateral anal sphincterotomy. At baseline and at 2 weeks, 4 weeks, and 8 weeks the patients were evaluated for symptomatic improvement, healing of fissure, and side effects.
Results: Total 68 patients were included in study, 34 in each group. The mean age of patients was 42.5 ± 11.2 years in the GTN group versus 41.8 ± 10.9 years in the lateral sphincterotomy group. There was no significant difference between age among the two groups (p=0.75). The mean VAS score was 8.2 ± 1.1 in the GTN group at baseline, and it decreased to 3.4 ± 1.3 at 2 weeks, 2.1 ± 1.0 at 4 weeks and then to below the mild pain threshold (1.8 ± 0.9) from week-8.
Conclusion: In terms of relieves of pain, fissure healing and lower recurrence rates lateral sphincterotomy is more effective than glyceryl trinitrate ointment in treatment of chronic anal fissure.
