Gastroscopy & Biopsy

Procedure:

  • A gastroscopy is a procedure that is applied by using a thin, flexible tube called an endoscope to look inside the esophagus (gullet), stomach and first part of the small intestine (duodenum).
  • It's also sometimes referred to as an upper gastrointestinal endoscopy.
  • The endoscope has a light and a camera at one end.
  • Gastroscopy may be used to diagnose a certain condition This allows the endoscopist to see any unusual redness, holes, lumps, blockages or other abnormalities.
  • If abnormalities are detected, a tissue sample (biopsy) can be removed and sent to a laboratory for closer examination under a microscope. Patient won't feel anything while the sample is removed. 
  • A gastroscopy often takes less than 15 minutes, & takes longer only if it's being used to treat a condition.
  • Patients are sedated while endoscopy, & shouldn’t drive home by themselves


Preparation:

  • Patients will be told whether or not they need to stop taking any of their medications beforehand. Medicines as insulin or metformin, any blood-thinning medication (used to prevent blood clots), such as low-dose aspirin, warfarin or clopidogrel patients will be instructed to stop taking up to 2 weeks before the procedure, this is because the medication can mask some of the problems that a gastroscopy needs to find.
  • It's also important that the stomach should be empty during a gastroscopy, so the whole area can be seen clearly.
  • Patients are usually asked not to eat anything for 6 to 8 hours before the procedure, and to stop drinking 2 to 3 hours before the procedure.
