Small bowel tumors

Gastrointest Endosc Clin N Am. 2009 Jul;19(3):461-79. doi: 10.1016/j.giec.2009.04.012.


Although rare, small bowel tumors may cause significant morbidity and mortality if left undetected. New endoscopic modalities allow full examination of the small bowel with improved diagnosis. However, isolated mass lesions may be missed by capsule endoscopy or incomplete balloon-assisted enteroscopy. Therefore the use of radiologic imaging and intraoperative enteroscopy for diagnosis should not be forgotten. Endoscopic resection of small bowel polyps and certain vascular tumors is possible but requires proper training. Advances in endoscopic tools are likely to broaden the endoscopic management of small bowel tumors. This article describes the general features of small bowel tumors, clinical presentation, and diagnostic tests followed by a description of the more common tumor types and their management.
