 Recently, transnasal endoscopy has met the growing demand for stomach mass examination in regional community-based screening. In this article, pretreatment procedures and technical tips for transnasal endoscopy are outlined. When choosing the route and pretreatment of nasal endoscopy, a physician should always take into account the careful operation of a flexible tube to reduce the risk of an accident and decrease the pain that a patient may feel during the procedure. Endoscopic examination, including transnasal endoscopy, should employ an appropriate volume of air and visualize the entire range of the stomach to avoid overlooking any lesion. Also, an adequate number of photographs is required, and between 30 and 40 photographs is suggested per person because it is difficult to review more than 40 photographs and less than 30 photographs may provide an incomplete assessment. It is critical to understand that the outcome of transnasal endoscopy strongly depends on the visualization of areas that are difficult to reach and on the appropriate adjustment of the air volume.
