5. Endoscopy simulator training

In the begining, the control part (left hand) is waist-level.

In the esophagus, try to keep the center of the lumen.

Try to use the torque by rotating the endoscope.

Esophago-gastric junction.

Picture from cardia. The direction of the gastric folds is 4 o'clock.

Normal pathway of the endoscope. Try to turn right (= clockwise rotation) while pushing the endoscope into the antrum.

Try to kee the endoscope close to the lesseur curvature and posteriow wall.

In the lower body, the direction of the gastric folds should be 12 o'clock.

In the greater curvature side of the antrum, you can see a polyp.

In pushing the endoscope from the cardia to the antrum, the control part (left hand) needs to be elevated to the break-level in order to make the rotation easy.

Withdraw the endoscopy about 15cm to reach the greater curvature of the lower body.

Angle up acutely 180o while pushing the endoscope about 10cm to see the gastric angle.

Rotate the shaft counter-clockwise about 90o to reach the anterior wall.

Pull back slowly to see the cardia.

Rotate the shaft to obtain complete views of the fundus and cardia.

Keep the shaft of the endoscope as straight as possible.

Push the endoscope to see the angle.

Rotate the shaft clockwise about 90o to make to angle horizontal.

Release the Up knob to see the antrum and lower body.

Withdraw the endoscope while oberserving the gastric body. Try to keep the endoscope close to the lesseur curvature and posteriow wall. Rotate the shaft counter-clockwise about 90o.

Border between high body and fundus (no folds).

Angle up a little bit and rotate the shaft couter-clockwise to see the fundus.

Withdraw the endoscope slowly.
