Painless gastroscopy

Compared with the general gastroscope, the painless gastroscope means that the patient is anesthetized by the doctor before the gastroscopy is performed, which can reduce the examination time and reduce the pain of the patient. Under the painless electronic gastroscope, a number of minimally invasive treatments for gastrointestinal bleeding, polyps, and ulcer stenosis can be performed to protect patients from surgery.

Inspection process Painless gastroscopy is based on common gastroscopy, with intravenous injection of propofol, fentanyl and lidocaine. During the gastroscopy, the patient quickly enters a state of drowsiness, and the pharyngeal muscles are slack, which helps the gastroscope to advance. Through a fiber tube with a diameter of only one centimeter, cold light is delivered from the oral cavity through the esophagus and stomach cavity to the descending part of the duodenum to illuminate the esophagus, stomach cavity and duodenum. The miniature camera carried at the front end of the gastroscope is used to simultaneously record images in the lumen in a synchronized manner. Bright, clear intracavity images are dynamically rendered on the HD video display. Not suitable for the crowd Not suitable for people: 1.
