The pressure of modern people is increasing, and more and more people unknowingly get involved with rectal polyps between their hurried steps. The presence of polyps in the rectum not only affects our health, but also poses a growing threat if such polyps become cancerous. Rectal polyp: is a benign rectal tumor, is a mucosa-covered swelling in the rectum, a small nodular mucosal bulge or a large mass with a tip, generally a single, a few for multiple, if many polyps gathered rectum or involved in the colon is called polyposis. First, the clinical manifestations of rectal polyps are mostly asymptomatic, most of which are found during physical examination. If the polyps are large and often subject to fecal friction, the mucosa can be eroded, and there is blood and mucus in the feces. The common symptoms are bright red blood, not much blood, mixed with mucus, blood mostly on the surface of the stool, if the bleeding volume, or bleeding for a long time, can cause wasting, anemia, polyps larger, can also appear the symptoms of urgency, constipation, anal discharge and more. 1, easy to cancer: many patients with solitary polyps, initially do not pay attention to, it is likely to multiple polyps transformation, and the chance of multiple polyps cancer is very high; 2, intestinal overlap: sometimes larger polyps can also cause intestinal overlap, resulting in intestinal obstruction and abdominal pain; 3, prolapse: polyps larger or more, due to the relationship between gravity pulling the intestinal mucosa, so that it gradually separated from the muscle layer and downward prolapse. The patient’s bowel movement pulling and intestinal peristaltic stimulation can make the mucosal layer around the base relax, which can be complicated by rectal prolapse. Third, the examination rectal polyps and normal disease as early as possible, otherwise the condition is aggravated, then rectal polyps in the hospital to do what examination? Generally rectal polyps to do three kinds of examination, respectively: 1, rectal finger examination: its symptoms are: polyps in the middle and lower rectum, rectal polyps with finger detection can be touched soft, smooth, active nodules. In 70% of patients, a soft, pea-sized round swelling can be palpated on rectal examination, which can be moved without pressure pain. And the location of rectal polyps is higher or smaller polyps, rectal examination is not easy to find, need to do other auxiliary examinations; 2, electronic anoscopy: more accurate diagnosis, hyperplastic polyps are more mounded raised nodules. Adenomatous polyps are round, with light red and shiny surface mucosa. Villi papillary adenomas are lobulated, cauliflower-like, and soft like large spongy polyps. Inflammatory polyps have long red tips; 3. If multiple polyps are found, sigmoidoscopy or fiberscopy is performed to exclude multiple polyps and colonic polyposis. Any polyps without a tip and wide base should be considered as precancerous lesions and should be examined by pathological section as early as possible. It is a relatively less painful kind of examination. Rectal polyps often grow in the lower back wall of the rectum (about 70%), 90% of the single, most with a tip, the tip length of 2-5cm, etc., can move. About 10% of polyps without a tip, generally less. What tests should be done for rectal polyps? Papillary polyps are often single, a few are multiple, the base is wide, no tip or short tip, the surface has a slender velvet-like protrusion, easy to malignant. Fiberoptic endoscopy is equipped with standard live-clamp sampling instruments, which can help to detect early lesions in the colon. Treatment 1.Electrocautery If the polyp is located high and cannot be removed from the anus, the polyp will be revealed by proctoscopy, sigmoidoscopy or fiberoptic colonoscopy, and the polyp with a tip will be removed by electrocautery with a trap over the tip. Electrocautery of wide based polyps is not safe. 2.Transanal resection For polyps in the lower rectum. Under sacral anesthesia, after dilating the anus, the polyp is pulled out with tissue forceps, and for benign polyps with tissues, the tissues are ligated and the polyps are removed; for broad-based polyps, part of the mucosa including the surrounding polyps should be removed and the wound is sutured; in case of villous adenoma, the cut line is not less than 1 cm from the adenoma margin seen by the naked eye. 3.Microsurgical resection under anoscope Suitable for local excision of adenoma and early rectal cancer in the upper rectum. After anesthesia, the anoscope for microsurgery is inserted through the anus, and the polyps are removed microscopically by magnifying the surgical field through the TV screen. Compared with electrocautery resection, the advantage is that the wound can be sutured after resection, avoiding complications such as postoperative bleeding and perforation.
