There is a jagged visible line at the junction of anal canal skin and rectal mucosa, which is called anal canal dentate line. Above the dentate line are internal hemorrhoids; Below the dentate line are external hemorrhoids covering the anal mucosa, which can be divided into connective tissue external hemorrhoids, varicose external hemorrhoids and thrombotic external hemorrhoids; Mixed hemorrhoids with internal hemorrhoids and external hemorrhoids are the fusion of internal hemorrhoids and corresponding external hemorrhoids through venous plexus, that is, the anastomosis of upper and lower venous plexus. When the mixed hemorrhoid emerges from the anus and is plum blossom-shaped, it is called circular hemorrhoid. If incarcerated by sphincter, incarcerated hemorrhoids will be formed.
You can choose a hospital with anorectal department for treatment.
