Bright red anal bleeding without pain is mostly considered to be hemorrhoids or rectal polyps. In addition, diseases such as rectal adenoma or rectal cancer may also cause such manifestations, but the incidence is relatively low and one should not let down one’s guard. It is recommended that patients go to the doctor for anal finger diagnosis or proctoscopy to avoid misdiagnosis or omission of serious diseases and standardized treatment after diagnosis: 1. Hemorrhoids: Especially internal hemorrhoids, which are caused by lesions in the supporting structures of the anal cushion, the venous plexus and the anastomotic branches of the arteries, resulting in congestion, hyperplasia and displacement of the anal cushion. intermittent fresh blood after stool is the most common symptom of internal hemorrhoids, and the blood is not mixed with stool. degree I internal hemorrhoids manifest as If the hemorrhoids are of degree I or higher, they can be seen to be prolapsed through anal visual examination. If there is only anal bleeding, conservative treatment such as hot water baths and increased intake of fibrous foods to keep the stool open, as well as injection of sclerosing agents and ligatures can be used. If symptoms worsen, surgical indications need to be evaluated, and if necessary, surgical treatment; 2, rectal polyps: common manifestations of intestinal bleeding, can be accompanied by abdominal pain, inflammatory polyps are mostly due to schistosomiasis or bacterial dysentery and other inflammatory response to stimulate the intestinal epithelium, clinical treatment of primary intestinal diseases; hyperplastic polyps are the most common non-neoplastic polyps, usually do not require special treatment; 3, rectal tumors: for example Rectal adenoma has certain tendency of malignant transformation, while rectal cancer has no obvious symptoms in the early stage. After the lesion breaks down and bleeds, it can cause rectal irritation symptoms, change in stool nature and defecation habit, rectal finger diagnosis can often palpate the mass, which needs to be combined with endoscopic examination and biopsy to clarify the nature of the mass, and most of them need to be treated surgically. If rectal cancer develops, radiotherapy, chemotherapy, targeted therapy, etc. are also required.
