A bowel-like object at the anal opening is generally referred to clinically as rectal prolapse, a disease in which the rectal mucosa, the entire rectum, the anal canal, or even part of the sigmoid colon is displaced downward and prolapses out of the anus due to poor defecation habits or strenuous defecation. Patients can have symptoms such as rectal prolapse outside the anus, constipation, diarrhea, local edema, etc. It is mostly seen in internal hemorrhoids, external hemorrhoids, rectal polyps, anal papillary hypertrophy, etc. And according to the degree of prolapse, there are Ⅰ degree prolapse, Ⅱ degree prolapse and Ⅲ degree prolapse. 1. Ⅰ degree prolapse: the length of prolapse of rectal mucosa is relatively short, light red, soft to touch, inelastic, not easy to bleed, and can be retracted after stool; 2. Ⅱ degree prolapse: the rectum Total prolapse, cone-shaped, light red, cup-shaped and cup-shaped surface, with layered mucosal folds, which need to be retracted by hand; 3, Ⅲ degree prolapse: prolapse of rectum or part of sigmoid colon, hypertrophy when touched, and loose and weak anus. Patients with rectal mucosal prolapse need to consult a doctor in time, and a professional doctor will choose the treatment according to the degree of prolapse, such as correcting constipation and developing good defecation habits. If the prolapse of rectal mucosa is prolonged and symptoms such as congestion and edema appear, it needs to be pushed into the anus using manual repositioning and, if necessary, surgical treatment to improve the above symptoms.
