 Routine observation and photography of the upper GI endoscopy can be performed by three methods, namely A, B, and C. Endoscopic images are obtained from the oral site of the stomach to its anal site in the method A, whereas these are obtained from the anal site of the stomach to its oral site in the method B. In the recommended method C, the observation and photography of the stomach angle are performed first ; followed by that of the antrum and duodenum ; the whole body ; and, lastly, the cardiac portion and fornix by reversing the direction of the endoscope. As each method has its own advantages and disadvantages, standardizing the methods in gastric cancer screening is imperative. Some crucial points are as follows:(a)the endoscopic photography technique should render each region comprehensible to a second judging doctor ; (b)all gastric parts should be included during endoscopic photography ; (c)an adequate degree of brightness, the cleaning of endoscopic lens, and the removal of attached mucous on the gastric mucosa surface should be ensured ; and(d)abnormal endoscopic findings must be prudently examined using adjacent observation and image-enhanced endoscopy post stomach screening.
