Clinical Trial Summary

To explore the impact on genetic and environmental factors for clinical manifestation, and the progression of chronic pancreatitis, including development of pancreatic insufficiency and other complications.

Description:

The present study was an observational study aimed to explore the impact of genetic factors (rare pathogenic variants of CP) and environmental factors(smoking and alcohol assumption) on the clinical manifestation and progression of CP. The observation items included the pain patterns, incidence of complications of CP, pancreatic cancer and death.
