First, from the pathological nature: hemorrhoids are venous masses formed by anal varicose veins, which rupture and bleed or form thrombi, causing severe pain after stool friction. In clinical medicine, hemorrhoids are divided into internal hemorrhoids, external hemorrhoids and mixed hemorrhoids. Rectal polyp generally refers to a protuberant lesion protruding from the surface of rectal mucosa into the intestinal cavity. Its pathological properties are different, some are benign tumors, some are the result of inflammatory hyperplasia, which are similar to the naked eye. Pathology includes adenoma, villous adenoma, juvenile polyp, familial polyposis and inflammatory polyp. Polyps may be precancerous lesions. Some polyps will become rectal cancer.

Second, from the etiology: the main causes of hemorrhoids are habitual constipation, increased portal vein pressure and increased intra-abdominal pressure. Rectal polyps are mainly caused by inflammatory stimulation, or genetic factors, fecal stimulation and so on.

Third, from the symptoms: the main symptoms of internal hemorrhoids: bloody stool, initial toilet paper with blood or drop of blood, and blood can be sprayed when it is heavy; Tumor prolapse can recover itself in the early stage, and when it is serious in the later stage, the tumor gets stuck in the anus and cannot recover, forming incarcerated hemorrhoids; Itching is accompanied for a long time. The main symptoms of external hemorrhoids: anal swelling, pain and foreign body sensation. The main symptoms of mixed hemorrhoids: bloody stool, pain and itching caused by anal dilatation. At first, it was stained with blood by toilet paper, occasionally bleeding and ejection. Hemorrhoids come out after defecation in the later period, and there is foreign body sensation, constipation, or uncomfortable defecation in some areas. The main symptoms of rectal polyps are hematochezia, prolapse and intestinal irritation. For anorectal diseases, patients need to find them in time, go to regular professional hospitals for examination and treatment in time, and delay treatment or avoid medical treatment for a long time, which will not only miss the best treatment period of the disease, but also lead to a series of serious complications.
