Endoscopic retrograde cholangiopancreatography resection of a neuroendocrine tumor in the papilla of Vater.

Neuroendocrine tumors (NETs) of the Papilla of vater are rare. We present the case of a 48-year-old male who was referred after a papillary mass was detected in an upper GI endoscopy. MRCP showed bile duct dilation and a 9 mm nodule in the papilla of vater. Endoscopic ultrasonography identified a hypoechoic lesion. Snare papillary resection of the enlarged papilla was performed. The snare tip was positioned at the tumor apex, gradually expanded to encircle the base, and tightened to ensure complete tumor inclusion. A papillectomy was performed, followed by pancreatic duct stenting after guidewire cannulation. Hemostasis was achieved using hot biopsy forceps and titanium clips. Histopathology confirmed a G1 NET tumor. Follow-up ERCP performed one year later revealed no recurrence, with biopsy showing only inflammatory changes.
