GOMEZ ZULETA, Martín Alonso. Endoscopic Ultrasound for Evaluating Subepithelial Duodenal Lesions. Rev Col Gastroenterol [online]. 2015, vol.30, n.2, pp.205-210. ISSN 0120-9957.

Subepithelial lesions (SE) are rare. They are found in only one out of every 300 endoscopies (0.36%). Of these, only 10% are located in the duodenum. When endoscopy does detect a subepithelial lesion in the duodenum it is important to make an initial description of its size, shape, color, mobility, and consistency to touch. Next, a closed biopsy sample must be taken with pincers and analyzed to detect whether it is a cyst and whether it has a pillow sign which is highly suggestive of lipoma. When the lesion is neither a cyst nor a lipoma, endoscopic ultrasound is indicated, especially if the lesion is larger than one centimeter.

Keywords : Subepithelial; duodenum; EUS; GIST; neuroendocrine.
