Many patients in the outpatient clinic often mistake hemorrhoidal prolapse for rectal prolapse, and claim to be suffering from “prolapse of the anus”. Prolapse of the rectum is rectal prolapse, only Chinese medicine called prolapse of the anus, Western medicine called rectal prolapse, called different. In fact, rectal prolapse and hemorrhoidal prolapse is very different. 1, hemorrhoidal prolapse due to the hemorrhoidal nucleus more than obvious demarcation, hemorrhoidal nucleus mucosa is often congested, and due to the hemorrhoidal nucleus area mucosa for the migratory epithelium (rectal mucosal columnar epithelium and anal canal skin squamous epithelium between the transition zone), the color is more purplish red. And because of the prolapsed hemorrhoidal nucleus within the varicose blood vessel mass, so its surface is sometimes mulberry-like. Rectal prolapse in the early stage of rectal mucosa prolapse, or half ring or full circumference, the swelling has no obvious boundaries, the surface is pink, sometimes appear ring folds. To the late stage, such as for the rectum whole layer (including the muscle layer) prolapse, it is difficult to see the swelling appeared folds, but a cone-shaped or column-shaped swelling prolapse. 2, hemorrhoidal prolapse volume is relatively small, sometimes only for a certain part of the hemorrhoidal nucleus prolapse, even if the hemorrhoidal nucleus all prolapse, its volume is not as large as the rectal prolapse, especially when the latter is accompanied by the muscular layer of the prolapse, the volume of the prolapse is relatively larger, sometimes the prolapse of the length of the material can be up to 400px, or even longer. 3, an interesting phenomenon is hemorrhoidal prolapse often lead to anal tightness or narrowing, rectal prolapse repeatedly prolapse instead of anal relaxation. Hemorrhoidal prolapse is only submucosal tendon rupture, not accompanied by muscle layer prolapse. Repeated hemorrhoidal prolapse due to chronic inflammatory stimulation, the original hemorrhoidal nucleus tissue fibrosis, and perennial hemorrhoidal prolapse, edema, inflammatory stimulation, can lead to anal pain, repeated spasm of the anal sphincter, and ultimately in the surface layer of the sphincter appeared in the fibrotic hyperplasia, appeared in the anus becomes small, defecation difficulties, once the patient Nu struggle, more likely to lead to the hemorrhoidal nucleus of the outward prolapse, the formation of a vicious circle. This is a common clinical reason for mild anal stenosis without surgery. Rectal prolapse is just the opposite, due to the prolapse of the rectum of the whole layer, over the years, and ultimately the entire anal sphincter completely “loose”, which is like a spring repeatedly pulled, and one day the elasticity will be greatly weakened. Of course, there is a vicious circle of rectal prolapse, that is, rectal prolapse led to the anal sphincter relaxation, and anal sphincter relaxation, weakening of the tension, the pressure of the anal canal significantly reduced, can not fight against the vertical pressure from the rectum, which led to the inertia of the prolapse of the rectum out of the prolapsed, so the operation should be restored to the pressure balance of the anorectal, in order to cure the disease.
