Objective: Anal fissure is a common health problem that affects the quality of life of young patients. The aim of our study was to benchmark results of lateral internal sphincterotomy (LIS) and botulinum toxin injection in the treatment of chronic anal fissure.

Methods: This multi-center, retrospective study used data from 135 chronic anal fissure patients. Patients' demographic features, clinical findings, fissure characteristics, post-defecation pain score, rectal bleeding or pruritus, and treatment satisfaction scores were recorded. Patients’ data were collected from the hospital records and patients with all of this data available were called and invited to the hospital for examination.

Results: Seventy-four LIS and 61 botulinum toxin applied patients were included. Symptom duration, hospitalization period, and duration of remission of complaints after the treatment were significantly higher in the LIS group (p<0.001). However, pruritus in anus and relapses were found to be higher in the botulinum toxin group (p=¬ 0.04 and p= 0.043, respectively). Abscess and fistula were observed in one patient's perianal region in the LIS group, and an abscess was observed in one patient in the botulinum toxin group. There was no significant difference in treatment satisfaction rates and postoperative complications.

Conclusion: Botulinum toxin yields satisfying results that are comparable to LIS. Patient selection may help mitigate this disease and allow it to be considered a good alternative option to surgery.
