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 (below 6 mm in size) non-malignant duodenal adenomas.
Weak recommendation, low quality evidence.

6 ESGE recommends endoscopic mucosal resection (EMR) as the first-line endoscopic resection technique for nonmalignant large nonampullary duodenal adenomas.
Strong recommendation, moderate quality evidence.

7 ESGE recommends that endoscopic submucosal dissection (ESD) for duodenal adenomas is an effective resection technique only in expert hands.
Strong recommendation, low quality evidence.

8 ESGE recommends using techniques that minimize adverse events such as immediate or delayed bleeding or perforation. These may include piecemeal resection, defect closure techniques, non-contact hemostasis, and other merging techniques, and these should be considered on a case-by-case basis.
Strong recommendation, low quality evidence.

8 ESGE recommends endoscopic surveillance 3 months after the index treatment. In cases of no recurrence, a further follow-up endoscopy should be done 1 year later. Thereafter, surveillance intervals should be adapted to the lesion site, en bloc resection status, and initial histological result.
Strong recommendation, low quality evidence.
