Methods of Colonic Transendoscopic Enteral Tubing

Our previous article has reported the method of colon TET. However, the investigators found that it was difficult to find the cavity because of the concentration of intestinal folds caused by the tube pulling after insertion of TET. It is well known that transparent cap‐assisted colonoscopy is easier to flatten the semilunar folds and improve mucosal exposure. Here the investigators test the hypothesis that using transparent cap‐assisted colonoscopy significantly decreases the second cecal intubation time which not only improve work efficiency, but also saves patients' anesthesia time and cost. Thus, the investigators design a prospective multicenter, randomized controlled trial. The aim of this study was to evaluate the methodology, efficiency, feasibility and safety of using transparent cap‐assisted endoscopy for colon TET implantation.
