Does gastroscopy cross infect?

Gastroscopy

is an invasive method of placing a flexible tube fiberscope into the stomach through the mouth and esophagus. Regular hospitals will strictly clean and disinfect the used gastroscope. If patients go to regular hospitals for gastroscopy, cross infection generally does not occur. However, if the hospital where the patient visits is irregular, or the gastroscope cleaning and disinfection are not standardized, cross infection may occur at this time.
