Sigmoid polyp resection is mainly related to the nature and size of the polyp, and common procedures include colonoscopic resection and radical colonic surgery. Patients with benign sigmoid polyps with a diameter of less than 2 centimeters are generally considered for colonoscopic resection. If the polyp is larger than 2 centimeters, it is difficult to completely remove it endoscopically, and partial resection of the sigmoid colon under laparoscopy is often considered. However, after pathological examination, if the patient is malignant polyp, radical sigmoid colon cancer surgery is often considered, and at the same time, the surrounding lymphatic cleared, and the patient, if accompanied by obstruction to be temporary stoma. This type of surgery is more complicated, with a large scope of injury and long operation time, and hospitalization is recommended. Therefore, it is recommended that patients should be examined in a timely manner if they have any discomfort, to clarify the nature of the polyp and the degree of disease progression, and to choose the appropriate treatment plan under the guidance of the doctor.
