Since the introduction of capsule endoscopy (CE), several studies suggested a higher frequency of small bowel tumors (SBTs) than previously reported.
Material and method: We evaluated the prevalence, presentation and diagnostic work-up of SBTs in patients undergoing CE in a single referral center. During 2003 - 2009, 102 patients underwent CE. For each patient with suspected SBT at CE, with subsequent histological confirmation, we registered clinical and biological features, imaging methods performed and management.
Results: SBTs were detected in 4.9% of patients undergoing CE. The main indication for CE was obscure gastrointestinal bleeding. All patients had undergone, before CE, at least one procedure evaluating the small bowel. All patients had iron-deficiency anemia, some presented also other gastrointestinal symptoms. The main SBT type was gastrointestinal stromal tumor. Three patients underwent single-balloon enteroscopy; surgery was performed in all patients. No retention of capsule occurred. CE could be used as first choice as diagnostic tool when SBTs are suspected.
