Anal mass prolapse refers to a protruding mass on the edge of the anus or prolapse of a mass in the anal canal and rectum outside the anus. It is collectively called anal prolapse in Chinese medicine. Clinically based on the relationship between tumor prolapse and defecation, if it prolapses during defecation, it can be returned to the anus by itself after defecation; some cannot be received after defecation or often outside the anus. Common diseases include:
1. Internal hemorrhoids: The internal hemorrhoids protrude outside the anus during the defecation, and the hemorrhoids after the defecation return spontaneously are stage II hemorrhoids; the hemorrhoids cannot be recovered after the defecation and need manual reduction is the stage III hemorrhoids. The hemorrhoids incarcerated outside the anus after defecation cannot be returned to stage IV hemorrhoids; the hemorrhoids are purplish red or bright red, resembling strawberry, and the mucous membrane is thin and easy to bleed.
