Transrectal Colorectal Polypectomy

Colorectal polyps are raised lesions on the mucosal surface of the intestine, mostly found in the rectum and sigmoid colon. Usually treated by rectal colorectal polypectomy. Treatment of diseases: colorectal lipoma, large intestine polyps Indication 1, adenomatous polyps. Including tubular, villous and tubular villous adenomas, this polyp has the highest probability of carcinogenesis, especially in the form of villi, known as precancerous lesions. 2. Inflammatory polyps. It includes polyps caused by inflammatory bowel diseases such as ulcerative colitis, Crohn's disease, and schistosomiasis. 3. A misformed tumor. Juvenile polyps and pigmented polyp syndrome. Contraindications This type of resection is not applicable to those who are unable to perform endoscopy, digestive disorder, uncorrected coagulopathy, large-diameter wide polyp, or pacemaker or elderly or infirm. Preoperative preparation Antibiotics are routinely used before surgery. Learn if the colorectal polyps are malignant. Surgical procedure 1. Disinfect the vulva vagina, spread the disinfection towel, expose the fibroids and the tumor pedicle. The exposed part of the fibroids of the rat tooth clamp was pulled down, and the hemostatic forceps were used to clamp the tumor pedicle up and down. The tumor pedicle is cut between the two clamps. The nodule was sutured with a No. 0 gut thread through the suture. 2. Clamp method If the submucosal fibroids are short and thick, the tumor is too large, the appearance can not see the pedicle, can be used to clamp the tumor pedicle with 2 long curved clamps, remove the tumor, and retain the proximal vascular clamp, after 24 to 48h Remove the vascular clamp. 3. If the curettage is not performed before surgery, pull the suture to one side and perform a full curettage to explore the intrauterine condition. If there is a submucosal or intermuscular fibroid, abdominal surgery is considered according to the condition. complication 1. Bleeding: Mainly due to the loosening of the pedicle of the jaws, the blood vessels are retracted, causing bleeding. After the discovery, according to the condition, if necessary, abdominal surgery to stop bleeding. 2. Infection: It can be caused by a preoperative fibroid infection, which is not controlled, and then spreads after surgery; 2 necrotic infection of fibroid stump. It is characterized by odor of vaginal secretions and elevated body temperature. Antibiotics should be applied in time to control infection. 3. Uterine injury is less common: more due to excessive traction of the tumor pedicle caused by partial valgus of the uterus, the uterus is worn through the pedicle of the fibroid. If the perforation is small and there is no infection, the uterine rupture can be sutured by laparotomy; if the injury area is large, hysterectomy should be performed.
