Obscure gastrointestinal bleed is a common problem facing gastroenterologists. Various radiological, endoscopic and surgical options are available to evaluate the cause of OGIB, each with their own advantages and shortfalls. The development of CE and DBE has transformed the approach to the evaluation and management of OGIB over the past decade. Older diagnostic modalities still play a complementary, albeit increasingly selective role. With growing experience in these new technologies, an ever-reducing minority of patients presenting with OGIB will be left without a diagnosis.
