Gastroscopy with Dilation

Gastroscopy is an examination of the inside of your oesophagus (gullet), the stomach and the duodenum (the first bend of the small intestine). A thin, flexible tube (a gastroscope) is passed through the mouth into the stomach. The tip of the endoscope contains a light and a tiny video camera.

Oesophageal dilation is a procedure to stretch open a narrowing which slows or prevents the passage of food through the gullet. A balloon or gradual dilator is used to stretch open the narrowing.
