Washed Microbiota Transplantation for Diabetic Gastroparesis

Официальное название

The Efficacy and Safety of WMT in the Treatment of Diabetic Gastroparesis: A Multicenter, Randomized, Double-blind, Placebo-controlled Study

Обзор

This is a randomized controlled trial to explore the efficacy and safety of washed microbiota transplantation (WMT) for diabetic gastroparesis (DGP) patients.

Подробное описание

At least 44 subjects who meet all the inclusion criteria but do not meet any exclusion criteria will be enrolled in this study. Data of demographic characteristics, Gastroparesis Cardinal Symptom Index (GCSI), Patient Assessment of Upper Gastrointestinal Symptom Severity Index (PAGI-SYM), Gastroparesis Core Symptom Daily Diary (GCS-DD), Patient Assessment of Upper Gastrointestinal Disorders-Quality of Life (PAGI-QoL), and clinical outcomes will be collected. After treatment, they will enter the follow-up period for efficacy and safety evaluation.
