Endoscopic management of superficial nonampullary duodenal tumors: European Society of Gastrointestinal Endoscopy (ESGE) Guideline

Abstract

Main recommendations 1 ESGE recommends that all duodenal adenomas should be considered for endoscopic resection as progression to invasive carcinoma is highly likely. Strong recommendation, low quality evidence. 2 ESGE recommends performance of a colonoscopy, if that has not yet been done, in cases of duodenal adenoma. Strong recommendation, low quality evidence. 3 ESGE recommends the use of the cap-assisted method when the location of the minor and/or major papilla and their relationship to a duodenal adenoma is not clearly established during forward-viewing endoscopy. Strong recommendation, moderate quality evidence. 4 ESGE recommends the routine use of a side-viewing endoscope when a laterally spreading adenoma with extension to the minor and/or major papilla is suspected. Strong recommendation, low quality evidence. 5 ESGE suggests cold snare polypectomy for small (
