The main symptoms of intramucosal prolapse of the rectum are difficulty in rectal evacuation and painful bowel movements. Difficulty in rectal evacuation and incomplete evacuation of feces: patients with rectal mucosal prolapse often need patients to insert their fingers or suppositories into the anus to assist in evacuation of feces, because inserting the fingers or suppositories into the anus can push the prolapsed rectal mucosa back to reset and relieve the cause of the obstruction, and over time, the patients will take this method from unconsciousness to conscientiousness to help in evacuation of feces. Symptoms of painful defecation: Some patients with rectal mucosal prolapse experience lower abdominal or periprosthetic pain during defecation, and occasionally bloody or mucus stools. Psychiatric symptoms (some patients have psychiatric symptoms, mostly depression or anxiety) and anal incontinence may also occur. Patients with intramucosal rectal prolapse should go to the hospital as soon as it is detected in order to understand the condition and give the necessary conditioning, prevention and related treatment.
