THE PANCKEATIO JUICE. 



cussing these properties, we shall, however, describe the 

 operation for establishing a pancreatic fistula. 



An incision having been made in the right hypochondrium 

 (i.e., right side) of a dog, below the ribs on one side, and 

 parallel with the median line, the duodenum is seized and 

 drawn out of the wound, together with the pancreas which is 

 attached to it. The larger of the two pancreatic ducts which 

 opens into the duodenum about half an inch below the com- 

 mon bile duct, is rapidly isolated from surrounding struc- 

 tures; and, having been opened, a small silver tube is intro- 

 duced into it and fastened by a ligature, which is passed 

 around it. The duodenum and pancreas are then returned 

 to the abdomen, and the wound is sewed up, care being taken 

 to leave the silver tube hanging out.
