Gastrointestinal Endoscopy

In medicine (gastroenterology), esophagogastroduodenoscopy or panendoscopy is a diagnostic endoscopic procedure that visualizes the upper part of the gastrointestinal tract upto the duodenum. It is considered a minimally invasive procedure since it does not require an incision into one of the major body cavities and does not require any significant recovery after the procedure (unless sedation or anesthesia has been used).
 

Diagnostic

• Unexplained anemia
• Upper gastrointestinal bleeding as evidenced by hematemesis or melena
• Persistent dyspepsia in patients over the age of 45 years
• Heartburn and chronic acid reflux - this can lead to a precancerous lesion called Barrett's esophagus
• Persistent vomiting
• Dysphagia - difficulty in swallowing
• Odynophagia - painful swallowing
• Persistent nausea
• Acid peptic disorders - to rule out gastric/duodenal ulcers
