Gastroenterostomy

This is a prospective, randomized, multicenter study to evaluate WMT in improving nutritional status in malnourished patients who underwent nonphysiological reconstruction of the upper gastrointestinal tract. In this multicenter trial, sixty-two patients will be enrolled in forteen Chinese sites. Participants will be randomized at a ratio of 1:1 to receive three WMTs through either mid-gut tube or colonic TET. After WMT, each participant will receive free diet plus home enteral nutrition. Home enteral nutrition should last for 2 months at home, with blood, urine and stool samples taken and stored at baseline and 2 months after WMT.
