It can be removed during colonoscopy. If the polyp is larger than 2cm, if a submucosal lesion is suspected, if the polyp is located in a place where it is difficult to operate the endoscope, if the polyp is taking aspirin, or if it has a bleeding tendency, resection is not possible during colonoscopy. . Polyps removed with an endoscope are taken out of the large intestine and subjected to a pathological examination.

Usually, in the case of a biopsy for diagnosis, only a small part of the nodule is removed for pathological observation, but in the case of polyps excised through polyp removal, the entire polyp is cut at intervals of about 2 mm and made into dozens of slides. Every detail will be thoroughly inspected. This is because it is necessary to check whether any part of the polyp has turned into cancer. Even after removal with an endoscope, polyps may continue to form in other areas, so you should continue to receive regular checkups.
