Introduction: Anal fissure, characterized by a painful ulcer in the anal canal, presents a significant medical challenge. While surgical approaches like lateral internal sphincterotomy (LIS) have been the gold standard for chronic anal fissures, they come with potential complications such as incontinence and abscess formation. In contrast, medical treatments, including topical glyceryl trinitrate and diltiazem, have emerged as alternatives, offering non-invasive options with potentially fewer complications.
Method: In this retrospective study, we evaluated 136 patients treated for chronic anal fissures between June 2019 and December 2022 at Balikesir University Hospital, comparing surgical and medical interventions. The study encompassed demographic analysis, treatment modalities, complete recovery, recurrence rates, and side effects/complications. Statistical analyses, including logistic regression, were performed to assess the efficacy and risks associated with different treatments.
Results: Our findings indicated a higher rate of complete recovery with surgical treatment (86.1%) compared to medical treatments (glyceryl trinitrate: 64.8%, diltiazem: 69.6%). However, no significant difference was observed in recurrence rates between treatment groups. Surgical intervention exhibited a higher incidence of complications such as incontinence and abscess formation, while medical treatments were associated with side effects like headache and gastrointestinal disturbances. Notably, diltiazem therapy showed outcomes comparable to other modalities, indicating its potential as an effective and safer alternative.
Conclusion: Despite the favorable outcomes of surgical treatment, considerations of potential complications underscore the importance of tailored approaches. Prospective, randomized controlled trials with larger cohorts are warranted to further elucidate the efficacy and safety profiles of medical treatments in chronic anal fissures, facilitating informed decision-making in clinical practice.
