In a previous study,1 it was indicated that there were marked anatomic and physiologic differences between obstructed loops of the duodenum and of the ileum in the dog. The anatomic observations have been in a large measure corroborated by Dragstedt, Lang and Millet.2 These investigators showed that distention of the intestine caused the greatest interference in the duodenum because of the anatomic distribution of the blood vessels in the duodenal wall.
We have nothing new to add to our anatomic studies already reported, but wish to record some additional data on the secretion rates, intraintestinal pressures, distensibilities, and bursting pressures of equalsized loops of the duodenum and ileum.
Dogs were anesthetized with ether, and simultaneous closed loops of equal size were made in the terminal duodenum and in the terminal ileum. This procedure was carried out by finding the duodenojejunal ligament and tying a flat tape
