Magnetically assisted capsule endoscopy in suspected acute upper-GI bleeding versus esophagogastroduodenoscopy in detecting focal lesions

This article was originally published here

Acute upper GI bleeding is common and requires investigation with esophagogastroduodenoscopy (EGD) but endotherapy is not always necessary. Magnetically assisted capsule endoscopy (MACE) uses a capsule steerable by an external magnet and allows examination of the upper GI tract and small bowel but its role in acute upper GI bleeding has not been assessed.
