1. Secure the drainage bag; avoid kinking of the tube 2. Measure drainage at least every shift; drainage during the first day may reach 500 to 1000 ml and then gradually decline 3. Apply ordered protective ointments around tube to prevent excoriation 4. When the tube is removed, usually in 7 days, observe stool for normal brown color, which indicates bile is again entering the duodenum T-tube tract removal – threaded catheter with basket ERCP removal – cut papilla of sphincter of Oddi enlarge opening, threaded cath with basket
