Resumo: ABSTRACT The internal hemorrhoid, rectal tumor, hypertrophic anal papilla, and secret fecal mass are regarded as the blocks embedded in the rectum. The above blocks hinder defecation, which will inevitably lead to excessive opening of the anal caliber. Once the limit is exceeded, the skin of the anal canal will tear and form anal fissure. Based on the study of historical evolution, hypothesis reasoning, clinical verification and comparison with other theories, a new concept of anal fissure etiology–impaction theory is proposed. The so-called impaction theory refers to the impaction (various primary lesions) in anorectum, which hinders defecation. When defecating, the anal canal expands beyond the limit, and the whole layer of anal canal skin splits, that is to say, anal fissure is formed.
