Transrectal polyp electrocautery resection

The pedicled polyps of the upper rectum or the lower sigmoid colon examined by proctoscopy or colonoscopy can be electroporated. Suspected malignant changes or multiple polyps should not be treated with this method. Treatment of diseases: anorectal polyps, rectal polyps Indication The pedicled polyps of the upper rectum or the lower sigmoid colon examined by proctoscopy or colonoscopy can be electroporated. Suspected malignant changes or multiple polyps should not be treated with this method. Contraindications The patient is too old and should be filled with poor general condition. Preoperative preparation 1. Into the liquid food 1 day before surgery, fasting after dinner, and take senna leaf fluid catharsis. 2. Clean the enema 2 to 3 hours before surgery. However, it is not advisable to use oral mannitol for intestinal cleansing. When mannitol is used for bowel preparation, high frequency electrocautery can remove polyps to cause gas explosion or extensive visceral damage in the large intestine. Surgical procedure 1. Position: chest and knee position or stone removal position, buttock pad is a metal electrode plate wrapped with wet gauze. 2. Proctoscopy or colonoscopy: slowly insert a rectal or colonoscope, and aspirate the residual fecal fluid to observe the number and exact location of the polyp. When the mirror is built in, the deflation should be minimized to avoid dilating the intestinal lumen, causing abdominal distension or abdominal pain and affecting the microscopic examination or electrocautery resection. 3. Resection of polyps: For pedicled polyps, a long-handle electrocautery connected to an effective electrode can be inserted into a proctoscope or a sigmoidoscope to burn and stop the pedicle. If there is a snare, it can be placed on the polyp pedicle, and the sleeve is gently tightened and then burnt. If you have a wide basal polyp, you can use a biopsy force to remove several pieces for biopsy, and then use the electrocautery to remove all the rest. If the polyp is too large, it can be removed in stages. If the polyp is deep or in the sigmoid colon, the polyp can be removed by high-frequency electrocautery with a fiberoptic colonoscopy. When the fiber colonoscopy finds the polyp, insert the electrocautery resection snare through the biopsy port, and slowly cover the polyp at 3mm away from the pedicle of the polypoid. Do not over-distract after the ring is closed, and then try to extract the gas from the intestine and start the electricity. Burning off. Note that after the power is turned on, the ring should not be too strong, in order to prevent the electrocoagulation from being insufficient and causing bleeding at the stump. At the same time, it should be noted that the electrocoagulation should not be too deep, so as to prevent the wound from being too deep and too deep and causing late secondary bleeding. complication Anal pain.
