 Upper endoscopy is commonly used as the first step in clinical screening for gastric cancer. However, it is an uncomfortable examination for the patient. Detection of a lesion in areas that are difficult to observe is laborious and careful inspection of abnormal lesions is essential, especially in the areas that are difficult to observe. The endoscopist must be sufficiently experienced to recognize an abnormal lesion and perform careful analysis. An experienced endoscopist will be aware of the endoscopic properties indicating cancer and thus avoid misdiagnosis and producing a false negative result. The endoscopist must be sufficiently trained to perform the examination with optimal patient comfort and still be thorough and careful enough to prevent false negatives.
