Due to the increase in the volume of hemorrhoid nucleus, it is squeezed by feces during defecation, so that it gradually separates from the muscular layer and protrudes out of the anus. Sometimes 1~2 hemorrhoids prolapse at the same time, sometimes all hemorrhoids prolapse together with rectal mucosa. Initially, it only comes out during defecation, and it can be returned by itself after defecation. If the symptoms are serious, they should be pushed back by hand or rested in bed before they can be reset. If the symptoms are more serious, except for prolapse during defecation, any exertion, walking, coughing, sneezing, squatting, etc. may be prolapsed; The prolapse of hemorrhoid is very susceptible to infection, and every time it is impacted due to inflammation, edema and pain, it is difficult to reset. Is prolapse of internal hemorrhoids a major symptom of hemorrhoids? . The internal hemorrhoid protruding from the anus is clamped by the sphincter, and the venous return is blocked. However, the arterial blood continues to input, which increases the volume of the hemorrhoid core until the arterial blood vessels are compressed, thrombosis occurs, and the hemorrhoid core becomes hard and painful, and it is difficult to send it back to the anus. Corresponding pathological changes often occur in the later stage:

Necrosis: Hemorrhoids are incarcerated outside the anus. Due to a series of pathological changes, local metabolites accumulate, which further aggravates the local edema of the anus and aggravates the incarceration of hemorrhoids. This is a vicious circle. Therefore, if the internal hemorrhoids are embedded for a long time, necrosis will inevitably occur. At this time, necrosis is often confined to the mucosal part of hemorrhoid nucleus, but it also invades other parts of human body. It has been reported abroad that the thrombus in the hemorrhoid core spreads upward and the necrotic area extends to the rectal wall, resulting in severe sepsis in the pelvic cavity. Although this kind of situation is rare, it must be highly valued by clinicians.

Infection: After incarceration of hemorrhoid nucleus, there are many different degrees of infection, and the patient has symptoms such as acute interior, severe abdominal distension, etc. At this time, the infection is mostly confined to the anus. If it is strongly reset, it is easy to spread the infection, causing submucosal, perianal or ischiorectal abscess. If the detached embolus with bacteria goes up the vein, plus improper use of antibiotics or no antibacterial drugs, it will form portal vein bacteremia or even sepsis, and also form liver abscess. There have been reports of fatal portal vein septicemia associated with incarceration of hemorrhoid nucleus abroad. Edit this paragraph. Generally speaking, can internal hemorrhoids of degree II and III be recovered? , IV degree can't, or because of infection, edema caused by incarceration can't be readmitted. It is easier for internal hemorrhoid to be taken back when it is just pulled out. After a long time of pulling out, local blood circulation will be blocked, which shows that venous return is blocked, while blood continues to be injected into the artery, and varicose veins or even thrombosis will occur in the pulled out part, and the volume will increase. At this time, the anus will spasm and contract due to pain, resulting in incarceration or even necrosis, infection, suppuration and rupture of the pulled out internal hemorrhoid, forming a vicious circle.

Therefore, when the internal hemorrhoid just comes out, it should be taken back in time. If it is difficult to take back, you can gently push it up when taking a bath in warm water. At this time, the anus is loose, which is conducive to taking back. Edit this paragraph to diagnose that in daily life, people often prolapse internal hemorrhoids and rectal prolapse? Confuse. Rectal prolapse refers to the downward displacement of rectal mucosa, anal canal, the whole layer of rectum and part of sigmoid colon, and the prolapse of internal hemorrhoids is due to the expansion, flexion and congestion of the submucosal hemorrhoid venous plexus above the anal tooth line at the lower end of rectum, resulting in the prolapse of soft venous plexus. Usually, the internal hemorrhoids in stage I do not prolapse, and only the hemorrhoid nucleus in stage II and III will prolapse. Therefore, it is not difficult to distinguish rectal prolapse from internal hemorrhoid prolapse from etiology, symptoms and prolapse.

Generally speaking, rectal prolapse is more common in the elderly and the physically weak, and the onset is related to constipation, diarrhea, underdeveloped pelvic organs and pelvis itself or muscle relaxation. It is often manifested as the whole rectum prolapse, and the mucous membrane under it is uniform and reddish, with smooth surface and spiral and layered shape. When defecating, it is prolapsed, and the lighter person can take it back by himself. With the progress of the disease, the prolapsed thing needs to be pushed by hand before it can be put back into the anus. For example, rectal prolapse for a long time is often stimulated by external objects, which is prone to ulcers, bleeding, itching and other symptoms. The prolapse of internal hemorrhoids is more common in patients with internal hemorrhoids in stage ⅱ and ⅲ. Generally, the prolapse is nodular and hyperemia on the surface, especially in three areas of maternal hemorrhoids-there is a groove between each hemorrhoid, which may be accompanied by bleeding. In addition, long-term internal hemorrhoid prolapse is prone to incarceration and necrosis if it cannot be recovered in time.
