Esaphago-gastroduodenoscopy (also called upper gastrointestinal scopy) is an examination of the esophagus, stomach, and duodenum.  The examination is carried out by means of a gastroscope, which is a flexible tube equipped with a camera on the end, a light system, and one or two work canals. The mucosa can be inspected and the images are transferred to a monitor.  

During a scopy, the following can also be carried out:

  • biopsy
  • polyp removal
  • treatment for bleeding
  • injection of medication
  • laser treatment of lesions 
  • dilatation of the esophagus

The examination is simple and is carried out at most hospitals. It is important the stomach is empty before the exam.


  • Diagnose changes in the mucosa (soreness, inflammation, benign or malignant tumors)
  • Monitor a sore in the stomach/duodenum
  • Find source and treat acute bleeding in the upper gastrointestinal tract. 


  • Diagnose and possibly definitive treatment
