With the improvement of people's health awareness, more and more people realize the importance of endoscopy. Compared with other imaging methods (such as gastrointestinal contrast, abdominal ultrasound, CT, MR, nuclear medicine, etc.), in addition to the diagnosis of diseases, endoscopy also has obvious advantages in obtaining specimens for further pathological examination. However, the pain and discomfort caused by endoscopy have discouraged many people and even missed the opportunity for early diagnosis. At present, painless endoscopy can improve this kind of situation, but everyone has various doubts about it. In order to accurately understand and grasp the needs of people in Suichang County for gastrointestinal endoscopy, so as to better carry out gastrointestinal endoscopy/screening/diagnosis and treatment work in the future, we designed this demand survey.

Exclusion Criteria:

• People who cannot cooperate, are unconscious, or who are unwilling to participate in questionnaire surveys.
