Incisional polypectomy

Incision of the intestinal wall polyp is used for the surgical treatment of rectal polyps. Rectal polyps are mostly distributed at the lower end of the rectum. They are round and have slender pedicles. They are mostly composed of mucous membranes and glands, which are connected to the intestinal wall. Some polyps are broad-based and pedicle-free. A few polyps are adenomas, and adenomatous polyps can be malignant, but rare in children. Rectal polyps are a common cause of blood in children. Some polyps grow close to the anal canal and can be prolapsed in the anus. Treating diseases: rectal polyps Indication Incision of the intestine wall polypectomy is applicable to: 1. The operation is adapted to larger polyps above the sigmoid colon, especially adenomatous polyps, which are wide and have more bleeding and cannot be removed by endoscopic electrocautery. 2. Large adenocarcinoma polyps of the rectum, short and wide, can not be resected by gastro-intestinal resection, can be through the posterior median sagittal approach, revealing the posterior wall of the rectum and cutting the intestine wall, and cutting the polyps under the vision. Then suture the intestinal wall. 3. Huge polyps block the intestines. Preoperative preparation 1. Prepare for intestinal sterilization by colon surgery for 3 days. The bowel was cleaned 1 night before the operation, and the bowel was cleaned again on the morning of the operation. 2. Perform a barium enema and fiber colonoscopy before surgery to confirm the diagnosis and identify the location of the polyp. Surgical procedure 1. Left abdomen rectus abdominis incision. After the laparotomy, the colon was probed in turn, and after the polyps were touched, the colon was presented outside the incision. The incision is protected with a saline gauze pad. The two ends of the intestine are clamped with a clamp of the intestine to prevent the contents of the intestine from overflowing after the intestine is cut and contaminating the abdominal cavity. 2. The intestine should be made with a longitudinal incision of 2 cm in length on the intestine wall corresponding to the polyp pedicle to remove the polyp. The pedicle was cut through the ligation and the polyps were removed. The intestine wall incision was sutured with a thin thread and the suture layer was sutured. complication The main complication of incision of the intestine wall polypectomy is postoperative intra-abdominal infection. The cause of infection is insufficient preoperative bowel preparation, intestinal contents are contaminated in the abdominal cavity during operation, or intraoperative suture of the intestine wall is not strict.
