2o8 Surgical Diseases and Surgery of the Dog 



In practical surgery it is very rare that operative interference 

 of the liver is indicated. A few instances of removal of tumors 

 have been recorded. But most liver tumors are secondary, show- 

 ing the disease to be generalized and operative measures useless. 



Partial Hepatectomy. To reach the organ most directly the 

 incision in the abdominal wall is made on the right side, extend- 

 ing from the ensiform process upwards close to the borders of the 

 ribs. A very large opening is usually necessary, particularly when 

 a very voluminous growth is present. An affected lobe should be 

 removed in its entirety, all vessels entering it being previously 

 secured. 



Gluck has counseled the employment of rubber bands in lieu 

 of ligatures. All bile should be promptly wiped away, as it is apt 

 to contain pyogenic microorganisms.

The Pancreas 



There are practically no diseases or lesions of the pancreas 

 which are remediable surgically. It is very rare that the organ 

 suffers injury either by direct or indirect violence, owing to its 

 remote location. Malignant neoplasms occasionally occur, but their 

 presence is seldom discovered until the disease process has ex- 

 tended and hopelessly involved other organs, notably the ductus 

 choledochus. Cysticercus cellulosae has occasionally been found 

 in the organ. 



Surgety of the Pancreas 



Berard and Colin have demonstrated that the pancreas has no 

 connection with the duodenum at one stage of its development. 

 It is originally composed of two distinct portions, the one lying 

 parallel to the duodenum, and the other perpendicular. Later
