i8o CANINE AND FELINE SURGERY 



Gastrectomy is done in the case of a malignant gro\\th 

 affecting the stomach, the diseased part being excised and the 

 health)- portions united b\' Lembert's or Czernj'-Lembert's 

 sutures. 



In gastrostom)- the stomach is opened and a fistula, through 

 which food is passed, permanentl}- established. 



Intussusception of the Intestine. 



This condition, a ' telescoping ' or ' invagination ' of one 

 portion of intestine into another, is most commonl)- met with 

 in j'oung animals, although adults are by no means exempt. 

 It is produced as a sequel to the violent peristalsis set up 

 b\' some irritant, such as indigestible food or the presence of 

 ^\•orms. /\s regards situation, the commonest \arieties are 

 the ileo-cftcal and the enteric. In the former the ileum is 

 in\'aginated into the colon, the intussusception extending as 

 far as. the ileo-caecal \'ah'e, and it maj' e^'en go so far as to 

 protrude through the anus to the extent of 5 or 6 inches 

 (see p. 106). 



Fig-. 140 is an illustration of this. The patient, a valuable bull puppy, 

 aged three months, was supposed to be suffering from prolapse of the 

 rectum, but upon closer e.xamination this was found to be the small 

 intestine, as when returned the intussusception could still be distinctly 

 felt at the end of the finger. Laparotomy was performed, an intussuscep- 

 tion of the ileum 8 inches long was reduced, and the patient made an 

 excellent recovery.' 



^^'ith the enteric variet}- the small intestine is protruded 

 into a portion of itself. 



Sometimes a number of puppies in the same kennel will 

 suffer about the same time, and unless a post-mortem is 

 made the cause will be inexplicable. 



The specimen shown in Fig. 128 was a portion of the small intestine of 

 a Chow-chow puppy, eight weeks old, and in the kennel from which it
