Heidenhain has employed a method of establishing permanent pancreatic fistulfe which he claims to have yielded in his hands satisfactory results. He excises that portion of the duodenum which contains the opening of the pan- creatic duct, restores the continuity of the gut, and sews the excised portion, after division lengthwise, to the abdominal wound, so that the orifice of the duct opens externally upon the abdominal surface. 1.

The Chemical Composition of Pancreatic Juice.—The pancreatic secretion differs in composition and physical properties according as it is obtained from permanent or temporary fistulae, and according to the ani- mal from which it is obtained. When obtained from temporary fistulas in the dog, it is a clear fluid, almost of the consistency of syrup, very. Fig. 160.—Pancreatic Fistula in the Ox. IColin.) tenacious, and of strongly alkaline reaction. It contains few or no struc- tural elements, though corpuscles similar to those found in saliva have been claimed by Kuhne to exist, and occasionally free particles of oil. It has a decided salty taste, and under the action of heat coagulates, as does the white of egg, to a firm white mass. Alkalies prevent the coagulation. When alcohol is added to the fresh pancreatic secretion it forms a copi- ous, white, flocculent precipitate, which is subsequently in large part, after filtration, soluble in water. When very dilute acids are added to pancreatic juice, they at first form a turbid mass which subsequently dissolves in excess of acid. This action is to be explained as due to the.
