Ulcerative colitis

This disease is an intestinal disease with unknown etiology, mainly superficial and nonspecific inflammatory lesions of rectum and colon. It mainly involves rectum and sigmoid colon, and can also invade other parts or all of colon; In severe cases, a few of them can have "reflux ileitis" within 10cm. The main clinical symptoms were mucus purulent bloody stool, abdominal pain, diarrhea or severe diarrhea; Acute critical cases have systemic symptoms and are often accompanied by extraintestinal diseases and liver damage, arthritis, skin damage, myocardial lesions, oral ulcer, iridocyclitis and endocrine diseases. Ulcerative colitis was first reported by Wilks and Moxon in 1875. In 1973, the International Organization Committee of Medical Sciences of the World Health Organization named the disease idiopathic colitis, also known as chronic nonspecific ulcerative colitis, in order to distinguish various specific inflammation. However, due to the clinical consistency, the name of ulcerative colitis is still widely used at home and abroad.
