Longitudinal Study on the Evolution Trend and Influencing Factors of Postoperative Reflux of Esophageal Cancer Based on PEPTEST Technique

The goal of this observational study intends to explore the evolution trend and related factors of postoperative reflux of esophageal cancer based on PEPTEST detection, in order to identify postoperative reflux The main question it aims to answer are: to provide evidence for high-risk groups, improvement of surgical methods for esophageal cancer, and development of health education programs to prevent postoperative reflux.

The incidence of pathological reflux at 5 time points before and after surgery was observed and compared (that is, both T-line and C-line were shown). The trend of pepsin content in saliva before and after operation; The relationship between pathological reflux and surgical factors; The relationship between pathological reflux and life habits after operation; Relationship between pathological regurgitation and demographic characteristics.
