Introduction: Fissure-in-ano is a common proctologic problem encountered. It is a tear in anal mucosa distal to dentate line usually seen in the posterior midline. Hypertonia of internal anal sphincter and local ischemia is thought to be the pathology behind anal fissures.
Aim: The present study aims at determining the prevalence and clinical presentation of fissure-in-ano.
Materials and Methods: This study is a cross-sectional study conducted at Tirunelveli Government Medical College in patients with anorectal ailments who were randomly selected in this study. The diagnosis was made on the basis of anorectal examination which included inspection, digital rectal examination, and proctoscopic examination.
Results: Our study found out that out of the 325 patients with anorectal ailments, 100 patients (30.7%) were having anal fissures. Out of them, 54 were males and 46 were females, majority were under 40 years age. Pain during defecation, bleeding and constipation were reported as the common clinical symptoms. 76% of patients with fissure-in-ano had an acute presentation and the most common location was reported to be posterior midline (98%).
Conclusion: Our study reveals that fissure-in-ano is a common proctologic disease. Lifestyle modification plays a major role in cure of this condition as constipation, and low fiber diet are the direct etiological factors.
