There are four possibilities for a bit of anal ectopia: one, prolapse of internal hemorrhoids; two, swelling of external hemorrhoids; three, possibly varicose pathological changes in the perianal plexus; and four, the most troublesome may also be prolapse. 1.If it is because of the prolapse of internal hemorrhoids, that is, suffering from internal hemorrhoids for a longer period of time, the condition develops to a more serious condition, the nucleus of the internal hemorrhoids will prolapse and in more serious cases, it will appear that it cannot be retracted and requires surgery. 2.External hemorrhoids are similar to the ectopia of internal hemorrhoids. 3.Perianal varicose plexus occurs, which is manifested when the patient exerts force to defecate, because too much force leads to obstruction of blood return flow The perianal area will also appear.4. If the prolapse is more serious, it is best to go to a regular anorectal specialist hospital to receive treatment in time. Once the anal prolapse occurs, you need to go to the hospital in time for treatment, and the prolapse of the swelling should not be retracted, and if it is retracted there will be severe pain.
