After the hemorrhoids hit the sclerosing agent, the hemorrhoidal nucleus of hemorrhoids gradually atrophied and became smaller, and ultimately improve the hemorrhoidal bleeding, hemorrhoidal nucleus prolapse of the symptoms, so as to avoid aggravation of the symptoms, induced anemia and other complications. Hemorrhoid injection sclerotherapy, the need to inject the sclerosing agent into the submucosal layer of the hemorrhoidal nucleus, so as not to destroy the physiological function of the mucosa, direct stimulation of the endothelium of the blood vessels and thus stimulate the formation of blood clots, causing inflammatory changes in the hemorrhoidal nucleus and fibrosis, so as to achieve hemorrhoidal sclerosis and hemostasis of the hemorrhoidal nucleus. Sclerosing agent, if injected too deeply into the muscle layer, may cause the risk of perianal muscle necrosis, so special attention should be paid when injecting. Hemorrhoidal patients injected with sclerosing agent, if there is burning sensation, local abscess and other abnormal phenomena, need to go to the regular hospital in a timely manner, handled by professional doctors. Sclerosing agent for mild non-extraction of internal hemorrhoids has the best efficacy, for bleeding serious stage I internal hemorrhoids can quickly stop bleeding. For more than two stages of internal hemorrhoids, with partial ligation can both stop bleeding and prevent hemorrhoidal core prolapse, further control the aggravation of hemorrhoids and the development of anemia and other complications. Patients with hemorrhoids, if there is obvious discomfort, it is recommended to promptly go to the hospital for examination, to clarify the cause of the disease, under the guidance of professional doctors, to take the most appropriate method of treatment.
