Abstract
Endoscopic polypectomy is the gold standard for the treatment of colorectal polyps. In the case of non-palpable lesions or to complete polyp removal, the lesions are located intra-operatively. With the advent of laparoscopy, identifying their position is even more important because there is no opportunity for intestinal palpation. Several methods of preoperative endoscopic marking have been proposed using different types of tattooing and recently using clips followed by ultrasonography detection. Innovative methods are analysed; magnetic endoscopic imaging is a reliable and accurate method for determining the anatomical position of the tip of the endoscope during colonoscopy. Radioguided colonic lesion identification needs a gamma detection probe. Endoscopic removal can be converted to endo-laparoscopic rendezvous, failing which, laparoscopic resection is a reliable and safe choice, offering all the advantages of minimally invasive surgical techniques.
