How long does it take to do gastroscopy?

Endoscopy requires adequate preparation and is usually performed without eating on the day of examination. The doctor's operation time is usually about 5-10 minutes, excluding appointments and waiting times. Painless endoscopy usually takes about 10-20 minutes due to long anesthesia and resuscitation times. If endoscopic surgery is necessary, it takes longer. In short, gastroscopy is a relatively less time-consuming method.
