Feasibility and Safety of Ttransendoscopic Enteral Tubing in Mid-gut

In recent years, fecal microbiota transplantation (FMT) has gained appeal as a therapeutic option worldwide. Traditionally, microbiota can be administered through the upper-gut, the mid-gut, and the lower-gut pathways. FMT via colonoscopy is a classic approach, but in our previous study on ulcerative colitis, those patients have difficulty to maintain the infused microbiota suspension for enough time through this way. Thus, the investigators designed the colonic transendoscopic enteral tubing (TET) technology, which made whole-colon administration of treatment and repeat FMTs possible. However, some patients are resistant to undergo bowel preparation for colonoscopy or some are not suitable for colonic delivering way. Therefore, mid-gut delivering way is an important option for those patients. In previous researches on FMT for Crohn's disease, patients and physician faced the similar problem that some patients need repeat FMT during hospitalization, and some may need enteral nutrition at the same time. In order to have a quicker and more convenient placement of mid-gut/nasal-jejunal TET tube than traditional methods, the investigators designed a novel mid-gut TET technique without further confirmation for the location of tube in gut by X-ray or other medical devices after the endoscopic procedure. This study aimed to evaluate the feasibility, safety, and value of the mid-gut TET technique.
