Gastroscopy

Gastroscopy is a medical procedure that allows a doctor to look inside the esophagus, stomach, and duodenum (the first part of the small intestine). The procedure is performed using a thin, flexible tube called a gastroscope.

Procedure

A gastroscopy is usually performed as an outpatient procedure. The patient is typically sedated or anesthetized for the procedure. The gastroscope is inserted through the mouth and down the esophagus into the stomach and duodenum. The doctor can then visually examine these areas for any abnormalities. The procedure usually takes about 15 to 20 minutes.

Uses

Gastroscopy is used to diagnose conditions such as gastritis, peptic ulcers, and gastroesophageal reflux disease (GERD). It can also be used to take a biopsy (a small sample of tissue) for further testing.

Risks

While gastroscopy is generally safe, there are some risks associated with the procedure. These can include bleeding, infection, and perforation of the stomach or esophagus. However, these complications are rare.

Preparation

Before a gastroscopy, patients are usually asked to fast for several hours. They may also need to stop taking certain medications.

After the Procedure

After the procedure, patients are usually monitored for a short time before being allowed to go home. They may experience some mild discomfort, such as a sore throat, but this usually resolves quickly.
