Abstract
The present experimental study was aimed to Describe, evaluate and compare between different techniques of experimental intestinal obstruction in dogs.
The present study was performed on 12 healthy mongrel dogs aging (9 months to 24 months) and weighing (12 to 15 kg). All dogs were subjected to full physical and clinical examination which includes; body temperature, Respiratory rate and Pulse rate.
Four types of techniques were used: A. Intestinal obstruction on the level of lumen (3 dogs were used), B. Intestinal obstruction on the level of lumen with fixed knot (3 dogs were used), C. Intestinal obstruction on the level of lumen with ligation of blood vessels (3 dogs were used), D. Experimental intussusception (3 dogs were used).
Dogs’ recoevery from anasethesia was smooth with no complications. The wounds showed no signs of infection and the sutures were removed after 8 days.
Soft food was introduced after one day of resolution of the obstruction with close observation of appetite, urination and defecation.
On conclusion: Intestinal obstruction techniques were almost the same in application with the exception of the intussusception which was the most complicated procedure. Time consumed during the procedures was higher in case of intussusception and in case of intestinal obstruction on the level of lumen with ligation of blood vessels. Clinical signs were almost the same with no significant variation within the four applied techniques. The effect on intestinal loop and intestinal viability considered to be prominent when blood vessels were included as in case of obstruction on the level of lumen with ligation of blood vessels and in intussusception where a large portion of intestinal loop is resected and then reanastmosed.
