There are various methods of classifying prolapse. In 1975, the National Conference on Proctology formulated a unified grading standard for prolapse, which divided prolapse into 3 degrees. The current clinical diagnosis is based on this classification and is divided into 3 degrees according to the severity of the prolapse. What are the different degrees of prolapse? First degree prolapse: When defecating or increasing abdominal pressure, the rectal mucosa moves down and prolapses out of the anus. The length of the prolapse is about 2-4 cm, the prolapse is light red, with radiating longitudinal grooves, soft to touch, inelastic, not easy to bleed, and can return on its own after defecation, with good function of the anal sphincter, which is consistent with the incomplete prolapse in the traditional classification. Second-degree prolapse: the whole rectum prolapses when the abdominal pressure is increased. The length is 5-8cm, red in color, conical in shape, and the surface is ring-like and layered with poke membrane wrinkles. Thicker to the touch, elastic, anal flaccid, need help to reset after the stool. It belongs to the traditional classification of complete prolapse. Second degree prolapse: when wandering or increasing abdominal pressure, the whole rectum of the anal canal and part of the sigmoid colon prolapse. It is more than 8cm long, cylindrical in shape, red in color, the ring-shaped wrinkle key disappears, very thick to touch, soft in quality, and the anus is loose and weak. It also disdains complete prolapse in the traditional classification method.
