Multimodal Endoscopic Diagnostics of Gastric Neuroendocrine Tumors

#1516

Introduction: From 1998 till 2014 in our institution we have diagnosed 72 type I gastric neuroendocrine tumors (NET) with upper gastrointestinal endoscopy.

Aim(s): At early stage (up to 2006) only white-light endoscopy was used for gastric NET diagnostics and all of them appeared as flat or polypoid reddish lesions in proximal stomach or gastric corpus.

Materials and methods: Since 2007 we started use narrow-band imaging (NBI) endoscopy and it allowed more accurate gastric NET diagnostics. All lesions with NBI examination had altered mucosal pit pattern: tortuous or dot-type. Moreover, with NBI it is possible to review not only pit pattern, but microvessel pattern also, and in all type I gastric NET we observed pathologic arborescent dilated microvessels.
