Upper Endoscopy
Back to Gastroenterology and Endoscopy /

Concept
Upper endoscopy is used for the examination of the esophagus, stomach and duodenum. this procedure is performed to investigate the reasons for swallowing difficulties, nausea, vomiting , reflux, bleeding, abdominal pain or chest pain.
How should you prepare yourself?
You stomach and duodenum should be empty; so you should stop eating and drinking 6 hours before the procedure.

What should you expect during the procedure?

  • The procedure takes 20 to 30 minutes
  • The physician will spray your throat with an agent that will avoid gagging
  • You will be given some sedatives that relax you during the exam
  • You will be asked to swallow for the procedure a thin, lighted tube called an endoscope, which will transmit the image of the inner part of the esophagus, stomach and duodenum into a video screen. This endoscope also will blow air in the stomach, thus making easier for examination.
  • Sometimes, the physician removes samples of tissues (as biopsy) for further investigations.   
  • This procedure shows the presence of abnormalities or bleeding that cannot be shown by x-ray

 

What to expect after the procedure?

  • You will need to rest 1 to 2 hours after the procedure, until medications wears off
  • In most cases, patients will feel nothing after the procedure, just a mild sore throat
  • Complications are very rare
