摘要: Gastric cancer is the fourth most common cancer in the world and the second most common cause of cancer death. The median survival period of advanced gastric cancer is less than 12 months, and early diagnosis of gastric cancer becomes extremely important to improve survival rate. However, in the past, the detection rate of early lesions using conventional white light endoscopes was relatively low, and narrowband spectral imaging technology had higher resolution for blood vessels and mucosa.

The median survival period of advanced gastric cancer is less than 12 months, and early diagnosis of gastric cancer becomes extremely important to improve survival rate. However, in the past, the detection rate of early lesions using conventional white light endoscopes was relatively low, and narrowband spectral imaging technology had higher resolution for blood vessels and mucosa. However, relying solely on NBI still had shortcomings, requiring a combination of magnifying endoscopy , indigo carmine staining, and acetic acid staining to improve its specificity and sensitivity.收起
