RESUMEN
Human understanding is one of the three virtues that are expected of physicians in Harrison's principles of internal medicine, and it was emphasized that a Shakespearean breadth is needed to be the true physician. Recently, there has been an increase in the need for human understanding, such as a continuous increase in GB stones, an association between the patient's life events and pancreaticobiliary diseases, an increase in autoimmune disease, and a high recurrence rate after treatment. Therefore, we attempted a holistic and fundamental approach for figuring out the pathogenesis of pancreaticobiliary diseases including human habit loop and adaptive response and suggests the model for the development of pancreaticobiliary disease considering human understanding.
