Colorectal polyps

Overview rectal polyp is he directly to the intestinal mucosal surface prominent uplift lesions, including adenoma (papillary adenomas, villous adenoma, etc.), children polyps, inflammatory polyps polyp disease. Be pedunculated polyp (Figure 2 -113), or Cranford. Figure 2 -113 1 rectal polyps, classification (1) new biological intestinal epithelial growth from the new biology, easy carcinogenesis. A tubular adenoma, villous adenoma, familial adenomatous polyps, lesions. (2) hamartoma normal tissue abnormalities mixed, such as juvenile polyposis, Peutz - Jeghers syndrome, a handful of cancer. (3) the inflammatory polyps, also called false polyps, chronic inflammation and intestinal ulcers caused by cancer generally do not occur. (4) No chemical classification of polyps, such as Gardner syndrome. Clinical manifestations (1) hematochezia out blood is light, often with the surface of the stool, inflammation, mucus blood. diarrhea and radiotherapy, and other symptoms. (2), the rectal mass at the bottom of the pedicle rectal polyps in the bowel may emerge when the anus, is a bright red, Park, Cherry-like, it can heal itself back. Cranford rectal polyps by referring to the need and anal endoscopic examination can be found. (3) refers to anal and endoscopic examination can touch on single or multiple polyps or pedicle Canton-based polyps, the former activity, The latter is more fixed-shaped polyp Park, soft, if polyps stiffen the surface uneven, fixed wall, it may be cancer. To clarify, for biopsy. (4) barium enema to understand the distribution of polyps. Treatment (1) polyp surgery in low rectal polyps, anus suture polyps base, remove the polyp. (2) -- rescetion application of the rectum or colon, pedicled small polyps and colorectal colon mirror or fiber endoscope. using snare trap the pedicle to electrocautery excision. (3) After ligation frozen for sigmoid microscope, use vacuum devices ligation, Aprons ligation in polyp base, Qualitative biopsy, the tumor size, the selection of frozen probe contact method frozen 2 ~ 3 minutes. so that the tumor occurred coagulative necrosis, a "removal" purpose. (4) resection of colorectal polyps in the colon disease, cancer possibility, should be widely involved with the colon, ileum for colorectal anastomosis, the left in the multiple rectal polyps, can be spread as electrocoagulation or cryosurgery. If cancer, cancer treatment should be.
