Abstract

The medical records of dogs treated in our veterinary hospital during a period of 15 years until 1978 were reviewed. Intestinal obstruction was diagnosed in 47 dogs, among which 51.06% were under 12 months of age and 80.85% were under 3 years. The period which elasped from the appearance of clinical signs to the operation of the obstructed intestines averaged about 5 days (ranging from 1 to 24 days). The presurgical hematological findings of 5 dogs with intestinal obstruction suggested hemoconcentration, low level chloride in the serum, and a rise in the whole blood pH. In the cases of intestinal obstruction in dogs, 87.23% were caused by foreign bodies and 12.77% with intussusceptions. The foreign bodies were stones (41.46%), corn-cobs (24.39%), and others. The cranial portions of the obstructing intestines were dilated 1.4 to 1.8 times as much as the caudal portions, and the intestines of the obstructing sites were 1.7 to 2.7 times larger than the caudal portions. The severely damaged intestines were excised partially from 2 patients and incised only from 45 patients. Three patients died during and after the intestinal operation, but 44 patients recovered to normal following surgery. Biopsy specimens of the caudal intestines of the obstructing sites revealed normal tissues, but the microscopical examinations showed epithelial desquamation, hyperaemic and hemorrhages in the lamina propria, and edema and hemorrhages in the muscle.
