| [ Summary ] | In recent years, various tumors of the small bowel have frequently been reported by using new modalities such as capsule endoscopy (CE) and double balloon endoscopy (DBE). We focused on malignant tumors of the small bowel which have relatively high incidence rates. Primary adenocarcinoma is found mostly in patients with abdominal masses or symptoms of strictures. Malignant lymphoma is found primarily in patients with abdominal masses. Gastrointestinal stromal tumors (GIST) of the small bowel are often found during further evaluations of obscure gastrointestinal bleedings (OGIB). Carcinoid tumors of the small bowel, which are relatively rare in Japan, often produce intermittent abdominal pain. It is still difficult to find malignant tumors of the small bowel in patients without symptoms. Most tumors are advanced when diagnosis is achieved. Aggressive and early examinations of the small bowel with CE or DBE may lead to improved prognoses. | |
