Gastroscopy: What It Is and How it Works

This blog post is about gastroscopy, which is a procedure that allows the doctor to examine the esophagus, stomach, small intestine or colon.

What is it?

Gastroscopy singapore is an important diagnostic tool for doctors to identify problems with the esophagus. Gastroscope is a thin, tube-like instrument that allows the doctor to see inside the person’s body using a camera on one end and an eyepiece at the other.

Procedure:

Gastroscopy involves inserting an instrument called a gastroscope through the person’s mouth into their stomach. The scope has a light source and a tiny video camera so that doctors can see what they are examining. This procedure is known as an upper endoscopy.

Why is itused?

It allows the doctor to look for abnormalities or problems that might cause symptoms such as dysphagia (difficulty swallowing), odynophagia (painful swallowing), nausea, vomiting, difficulty regurgitating and other gastrointestinal issues.

How is it done

Gastroscopy is performed under mild sedation, so the person remains comfortable during the procedure. The doctor will need to insert an endoscope through the mouth and into the esophagus and stomach. Doctors will also use forceps instruments during this procedure to remove tissue samples or biopsies.

Bottom line:

Once the procedure is complete, doctors will remove the scope and allow the patient to wake up. Doctors will then examine images of what they saw during their examination to diagnose or determine if further tests are needed.
