Endoscopic versus surgical resection of duodenal neuroendocrine neoplasms between 1 and 2 cm: a multi-centered retrospective cohort study

Recommendations for resection technique of duodenal neuroendocrine neoplasms (D-NEN) with a size between 10 and 20 mm are lacking. The primary aim was to compare overall survival (OS) and progression-free survival (PFS) after endoscopic resection (ER) with surgical resection (SR). The secondary aim was to assess the incidence and clinical variables correlated with OS.
