An Upper Endoscopy—also called Esophagogastroduodenoscopy (EGD)—is a minimally invasive procedure that allows gastroenterologists to visualize the upper digestive tract (esophagus, stomach, and duodenum) using a flexible camera-equipped tube.
It’s a crucial tool in diagnosing a wide array of conditions—prompting answers to the question: What disease can be detected by an endoscopy?
Diseases Detectable Through Upper Endoscopy
1. GERD & Barrett’s Esophagus
Detects inflammation and damage from gastroesophageal reflux disease (GERD), including Barrett’s esophagus—a precancerous condition
2. Peptic Ulcers
Identifies ulcers in the stomach or duodenum. Biopsies can confirm underlying causes like H. pylori infection
3. Upper GI Cancers & Tumors
Detects tumors—including esophageal and gastric cancers—or lymphomas, often confirmed via biopsy
4. Esophageal Varices
Enlarged veins in the esophagus, common in liver disease; can be both diagnosed and treated during EGD
5. Strictures & Structural Issues
Identifies narrowed areas (strictures), blockages, hiatal hernias, or foreign bodies in the upper GI tract
6. Celiac Disease
Biopsy of the small intestine during EGD can confirm diagnosis by revealing characteristic changes in the intestinal lining
7. Eosinophilic Esophagitis (EoE)
Endoscopy identifies hallmark features (like ridges or rings), while biopsy confirms eosinophil infiltration—the definitive diagnosis
8. Other Conditions
Gastritis, duodenitis, and esophagitis: inflammation detectable via visual exam and biopsy
H. pylori Infection: diagnosed through biopsy taken during EGD
Submucosal tumors and intestinal metaplasia (early changing cells linked to cancer): visible during upper endoscopy and confirmed with biopsies
