Procedure of gastroscopy

Gastroscopy is performed only by an experienced gastroenterologist in a properly equipped endoscopy suite. At times, it may be necessary to carry out this procedure in an emergency room or ICU bed.

Following sedation, the patient is asked to lie down on his side (although successful intubation is possible in other positions).

A hollow mouthpiece is inserted to protect the patient's teeth and facilitate instrument passage. The endoscope is slowly advanced orally and is "swallowed" by the patient.

Once past the throat region, the instrument is guided only under direct visualization. An important landmark is the Z-line at the gastro-esophageal junction, approximately 40 cm from the teeth. The tip is then advanced into the stomach, with gentle insufflation of air.

The various portions of the stomach are inspected. Following this, the tip is then passed through the stomach outlet, into the duodenum or the first part of the small intestine. Mucosal surfaces are reinspected as the instrument is withdrawn. The images obtained are magnified many times and viewed on a video screen. Procedures like biopsies, cytologic brushings, polypectomy, cauterization of bleeding lesions, etc, are performed as indicated.(5 Trusted Source
