The comparison made between two experimental models with obstructive jaundice, which were newly established reversible model and traditional bile duct ligation and internal drainage model, showed that the new model was superior to the traditional one. This study suggests that the new model would be an ideal model, which could replace the traditional one for studying obstructive jaundice.
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.
