Gastroscopy, also known as upper endoscopy, is a procedure used to examine the upper part of the digestive system, including the esophagus, stomach, and the first part of the small intestine (duodenum).
Purpose of the Procedure
Gastroscopy is performed to diagnose and, in some cases, treat conditions affecting the upper digestive system. It can help identify issues such as ulcers, inflammation, tumors, or sources of bleeding.
Procedure
- The patient's throat is numbed with a spray or gargle.
- A thin, flexible tube with a camera (endoscope) is passed through the mouth and down the throat.
- The doctor examines the lining of the esophagus, stomach, and duodenum.
- If necessary, small tissue samples (biopsies) can be taken for further examination.
- The procedure typically takes 15-30 minutes.
Note: Patients are usually given a sedative to help them relax during the procedure.
Benefits
- Direct visualization of the upper digestive tract
- Ability to take biopsies for definitive diagnosis
- Can be both diagnostic and therapeutic
- Minimally invasive compared to surgical alternatives
