Rectal polyps are bulging lesions that protrude from the intestinal mucosa into the intestinal lumen. They are generally soft and can be solitary or multiple, including adenomas (among them are villous adenomas), pediatric polyps, inflammatory polyps and polyposis, etc. The more common things are rectal adenomas and pediatric polyps; pediatric polyps mainly occur in children aged 5-10 years. Pathologically, their content varies, from benign tumors to the consequences of inflammatory hyperplasia. The clinical symptoms of pediatric intestinal polyps are mainly blood in the stool or blood dripping after the stool, the color of blood is bright red, the blood is attached to the surface of the stool, and the stool does not mix, the bleeding is not large, and similar to internal hemorrhoids bleeding, so when children have similar symptoms of internal hemorrhoids bleeding, the first consideration of intestinal polyps may; polyps with a long tip, when defecating out of the anus, like a cherry, bright red, after the stool can be self-returned to the anus. When the inflammation is complicated by infection, there may be mucus stools, frequent stools, incomplete stools, etc. Long-term wasting and anemia may occur. Any children between 5 and 10 years old with the above symptoms should consider the possibility of intestinal polyps, and the diagnosis can be made clearly by rectal examination and endoscopy; rectal examination can generally diagnose low intestinal polyps; while high intestinal polyps need to rely on endoscopy. Surgical treatment of intestinal polyps (1) surgical treatment of intestinal polyps of the finger pulling hook out ligation method: for children with low tipped polyps, take the stone position or squatting position, finger sleeve lubricated with the right index finger into the anus, hook the polyp, hook the polyp out of the anus, and then ligated with medical silk at the base of the polyp, the polyp slowly necrosis off. (2) Transanal resection: for polyps in the lower rectum, under sacral or local anesthesia, firstly, dilate the anus, lift the polyp out of the anus with fingers or tissue forceps, and remove the polyp by ligating or suturing the polyp root together with part of the mucosa. If it is a wide basal polyp, the mucosa around the polyp should be removed, and then the wound should be sutured; if it is a villous adenoma, the mucosa should be removed more than 1.0 cm around the adenoma. (3) electrocautery resection: those who cannot be removed through the anus, can be removed by proctoscopy, now for colonoscopy set polyp tip without electrocautery. Note that wide basal polyps this method is not safe. The cost of cautery for intestinal polyps varies and needs to be determined by the number, size and location of polyps. (4) Trans-fiber colonoscopy high frequency or microwave resection: for polyps with tips within 2.0 cm or smaller wide basal polyps, those without bleeding tendency can also be removed microscopically with microsurgical anoscope connected to TV screen, magnifying the field of view and removing polyps microscopically. (5) Open surgery for intestinal polyps: If the polyp is located high, or if the polyp is cancerous, or if the polyp is larger than 2.0 cm in diameter and has a wide base, local excision is done via the lower abdomen, and cancerous lesions are removed according to the principle of rectal cancer. (6) Lesion bowel resection: for high polyadenoma, consider doing lesion bowel resection when necessary.
