The Biobank Integrating Longitudinal ERCP Within a Prospective Chronic Pancreatitis Cohort

The Biobank Integrating Longitudinal ERCP within a Prospective Chronic Pancreatitis Cohort (BILE-CP) is a prospective longitudinal cohort study conducted in Hangzhou, Zhejiang Province, China. The study plans to consecutively enroll 1,500 patients with chronic pancreatitis for long-term follow-up (scheduled every 6 months). This cohort encompasses patients across the entire disease course of chronic pancreatitis, with a particular focus on and in-depth tracking of a sub-cohort of patients undergoing ERCP treatments. During baseline and follow-up visits, researchers will collect multidimensional data from participants, including sociodemographics, diet and lifestyle, emotional status and sleep quality, clinical phenotypes and disease characteristics, ERCP intervention details, clinical laboratory and imaging examinations, continuous glucose monitoring (CGM), and traditional Chinese medicine indicators. Concurrently, multi-site biological samples will be collected, including but not limited to blood, feces, bile, saliva, tongue coating, and urine.
