Obscure Gastrointestinal Bleeding

Rozhledy v chirurgii : mesicnik Ceskoslovenske chirurgicke spolecnosti, 2015
Obscure gastrointestinal bleeding (OGIB) is by far the most common indication for small bowel endoscopy, since a presumed bleeding source is usually attributed to the small intestine after negative esophagogastroduodenoscopy (EGD) and colonoscopy.

Obscure gastrointestinal bleeding

memo - Magazine of European Medical Oncology, 2009
Hypochromic, microcytic anaemia due to iron deficiency is usually caused by blood loss due to gynaecologic or gastrointestinal diseases.

Obscure gastrointestinal bleeding.
