ABSTRACT
The development of medicine has shifted from empirical medicine to evidence-based medicine, providing more scientific and precise clinical evidence for the diagnosis and treat-ment of human diseases, and to guide clinical practice and bring benefits to patients. However, there are still some diseases for which it is difficult to obtain large-scale evidence-based medical evidence for various reasons, especially some rare diseases and difficult and serious diseases. These rare diseases and difficult and serious diseases are often difficult to diagnose and treat in clinical practice, and need guidance and advice from highly qualified experts, thus, various expert consensuses have emerged. The authors analyze the recent expert consensus in the field of digestive diseases at home and abroad, and focus on the methods and pathways for the development of the international common clinical expert consensus. It is proposed that the current stage is in line with China's national condi-tions, based on the international perspective, and mastering the international consensus Delphi pathway, in order to further standardizing the method of developing expert consensus in the clinical field of China, significantly improve the academic level of expert consensus in China, provide scientific, standardized, and international-level expert consensus for the majority of clinical workers, and finally serve the majority of patients and ultimately serving clinical patients.
