Pill camera takes on the tube: a gentler way to see inside your stomach?

This study tested a new, less invasive way to look inside the stomach: a magnetic capsule (a small pill with a camera) that doctors can guide from outside the body. It was compared to the standard procedure, upper endoscopy (a long, flexible tube with a camera). 27 adults with stomach symptoms like pain or heartburn took part. The goal was to see if the capsule could find as many problems as the tube, and if patients preferred it.
