Anal fissure

An anal fissure is a longitudinal tear or ulceration in the squamous epithelium of the anoderm, typically extending from the dentate line to the anal verge This gastrointestinal condition affects both pediatric and adult populations and is most commonly initiated by local mechanical trauma from passing hard stools, chronic diarrhea, or vaginal delivery
