Carcinoma of the small intestine diagnosed by double balloon endoscopy

: There are no specific symptoms of patients with carcinoma of the small intestine. Therefore, it is difficult to diagnose in the early stage by imaging modalities such as radiological enteroclysis, computed tomography, and classical endoscopy. However, double balloon endoscopy makes it possible to diagnose the carcinoma of the entire small bowel by taking tissue samples for pathological assessment. The characteristic of endoscopic findings is irregular ulcerated tumor with malignant stricture. It is still difficult to find carcinoma of small intestine in patients without symptoms and most cases are advanced when diagnosis is achieved. We should try to diagnose in early stage by combining images modalities, capsule endoscopy and double balloon endoscopy safely and efficiently, resulting in improving the patients' prognosis.
