Brief Summary

Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.

Assessment of qualitative and quantitative composition of the intestinal microbiota in patients with CP; in patients with CP and PEI complication of mild to severe degree; patients with CP and PEI who underwent surgical intervention on the pancreas. Intergroup comparison of the microbial compositional characteristics and their analysis. Correction of enzyme replacement therapy in selected groups of patients with regard to the identified microbial characteristics. Assessment of the intestinal microbiota composition in dynamics after 6 (+1) months on the background of allocated therapy
