    3.
    Observe whether the barium is smooth through the esophagus, whether there is stenosis obstruction, niche shadow, whether the mucosal softness is normal, the form of barium through the cardia, observe in the right anterior oblique position, positive position, left anterior oblique position, and if necessary, point the tablet
    .

    4.
    The examination bed is flattened and the patient is turned twice to the right, with the aim of making the barium evenly coated on the surface of the gastric mucosa, forming a double contrast

    (2) Lie on your back in the left anterior oblique position, and observe the double contrast
    of air barium in the stomach and body of the stomach.
    (3) Prone (flipped to the right) right posterior oblique position (equivalent to left anterior oblique position), observe the filling phase
    of the duodenal bulb and descending part of the antrum.
