Many patients with prolapse will ask: How did it happen? Prolapse is an uncommon type of anorectal disease, but many people still suffer from it. This is why many patients want to know what the condition is like. There are many people who mistake prolapse for hemorrhoids, leading to a worsening of the condition. Prolapse develops slowly, with a feeling of anal drop or urgency in the early stages. The most common complaint is rectal prolapse itself, and in three-quarters of patients the complaint is a protruding anal swelling. So why does the condition of prolapse occur? What are the causes of prolapse? 1, congenital deficiency, underdevelopment, rectum lack of support from the surrounding soft tissue and sacral curvature; 2, qi and blood decline, aging organism weakness, women have given birth many times, pelvic muscle relaxation, not easy to fix, resulting in prolapse; 3, sickness for a long time, weakness, malnutrition or long diarrhea and dysentery, so that the fat of the sciatic rectal fossa is absorbed, the rectum lost support, which is also an explanation of what is going on prolapse; 4, internal hemorrhoids stage III, anorectal polyps, anorectal tumors and other conditions, often prolapse resulting in relaxation of the anal canal sphincter and traction of the rectal mucosa downward. It is also seen after internal hemorrhoid circumcision, which damages the skin of the anal canal and forms prolapse of the exposed rectal mucosa; 5. Prolapse may also be caused by increased abdominal pressure, due to long-term diarrhea, constipation, prostate hypertrophy, bladder stones, chronic cough and other diseases that persistently increase abdominal pressure, so that the submucosal tissue of the rectum relaxes and the mucosa separates from the muscle layer, leading to prolapse. What are the symptoms of prolapse? 1.Bleeding Generally, there is no bleeding symptom, but occasionally when the stool is dry, there is blood dripping from the mucous membrane, blood in the stool or blood when wiping with paper, but the amount of bleeding is small. 2.Distension Due to the submucosal prolapse, the patient’s rectum or colon is overlapped, pressing on the anus, resulting in distension, and some patients also feel paralysis in the femoral and lumbosacral areas. 3, prolapse This is the main symptom of prolapse of the anorectum, early prolapse of the rectal mucosa during defecation, reset on its own after defecation; with the development of the disease, the body’s resistance gradually weakened, the loss of treatment over time, the protrusion of the full rectum or part of the sigmoid colon, even when coughing, weight bearing, walking, squatting will also prolapse, and it is not easy to reset, the patient needs to push back by hand or bed After resting, it can be reset. 4.Embedding When the rectal part of the anus is prolapsed during the stool, it is not reset in time, and after a long time, the local venous rental reflux is obstructed, so it becomes inflamed and swollen, and leads to embedding. In this case, the mucosa gradually turns from red to dark red, and there may even be superficial mucosal erosion and necrosis or strangulation and necrosis of the prolapsed intestinal segment due to contraction of the anal sphincter. The patient’s symptoms may develop from local to generalized, with increased body temperature, loss of appetite, difficulty in urinating, loose stools, increased pain and swelling, restlessness, or even intestinal obstruction.
