Exclusion Criteria20

Interventions

OTHERwashed microbiota transplantation

Washed microbiota transplantation refers to the infusion of washed microbiota from healthy donor into patients' gastrointestinal tract. Participants will receive two doses of WMT for DGP.

OTHERplacebo

A carrier fluid with matching volume and consistent appearance to the infusion of washed microbiota.
