Testing with a spongy device that’s swallowed to collect esophageal cells and retrieved via a thread attached to it improved general practitioners’ detection of Barrett esophagus among patients with gastroesophageal reflux, according to a trial in The Lancet.
Novel Device Improves Barrett Esophagus Diagnosis in Primary Care
I cannot even get a gastroenterologist-referral from my primary care physicians to attempt diagnosis without a preceding colonoscopy or esophagogastroduodenoscopy (EGD), despite no case being made to suggest that either is needed for a Barrett’s esophagus diagnosis.
What makes you think you have Barrett’s? an endoscopy is I think the only way they can confirm you have it or not. Colonoscopy is not needed.
