Summary
Magnifying endoscopy provides high-resolution images that enhance the detection of early gastrointestinal lesions. However, conventional manual zoom techniques require frequent focal adjustments, which can be technically demanding and may compromise image stability, especially in complex anatomical settings. This study evaluates a novel one-click autofocus system based on image recognition and computer vision algorithms. The system automatically adjusts focal distance within seconds, eliminating the need for manual operation. This trial aims to compare the efficiency and image quality of one-click autofocus versus segmented manual focus in patients undergoing magnifying endoscopy for gastric diseases. A tandem randomized controlled trial will be conducted to assess procedure time, image clarity score, and operator satisfaction between the two techniques.
