Three types of intestinal loops were used to reestablish the internal drainage of bile in 17 cases. The leeway derived from the peristaltic cycle of the intestinal loop for gastrointestinal reflux pressure, the cholangeitis after operation from reflux following choladocho-intestinal anastomosis could be avoided, and, naturally it had changed the traditional method of purèly blockade of the reflux, thus the result from treatment was far more satisfactory.
