What's the difference between gastrointestinal endoscopy and anorectal endoscopy?

Gastroscope and colonoscopy are instruments for gastrointestinal endoscopy. Gastroenteroscopy generally refers to electronic gastroscope, and anorectal endoscopy generally refers to electronic enteroscope. The main difference is that gastroscope enters through the mouth and enteroscope enters through the anus.

The gastroscope is inserted into the stomach through the mouth, and the micro camera at the head end transmits the detected image to the monitor through the optical fiber, so that the pathological changes of the stomach can be observed very clearly, and even the bleeding point of the needle tip can be seen.
