Endoscopic removal of colorectal polyps is a minimally invasive procedure performed via endoscopy, specifically used for treating colorectal polyps. The procedure mainly involves the following steps: 1. Preoperative preparation: The patient is usually placed in a lateral position and administered general anesthesia to ensure comfort during the procedure. 2. Insertion and localization: The physician slowly inserts the colonoscope through the anus and performs a colonoscopic examination to precisely locate the polyp. 3. Polypectomy: Once the colonoscope reaches the site of the polyp, the physician injects physiological saline into the colonic mucosa to elevate the polyp, making it more prominent. Then, specialized instruments such as an electrocautery knife or a ligator are used to remove the polyp. 4. Hemostasis: After polyp removal, the physician applies hemostatic techniques such as electrocoagulation to control bleeding at the resection site. The entire procedure is typically performed under direct visualization, ensuring accuracy and safety. After the procedure, patients are required to follow medical advice regarding dietary adjustments and rest to promote wound healing.
