This study shows that endoscopic resection of polyps 5–19mm in size was incomplete in 1 out of 6 polypectomies, especially in those with a proximal location and for serrated lesions. Interestingly, no difference in incomplete resection rates was found between board-certified and trainee gastroenterologists.

An exhaustive review and analysis of the literature was undertaken by experts to develop this guideline, the first in the field of endoscopic management of ampullary tumors. A diagnostic and therapeutic algorithm is proposed that summarizes the various statements. A companion paper will provide guidance on superficial nonampullary tumors of the duodenum.
