Abstract
Background: Intussusception is the invagination or telescoping of one part of the bowel into an adjacent part which causes bowel obstruction, and compromises blood flow to the affected portion. It can occur anywhere along the gastrointestinal tract; however, usually occurs in the middle portion of the small intestine or where the small intestine joins the large intestine. Although ileocolic intussusception is common in dogs, its proper surgical management is urgent to save the life of the animal. Methods: Two mixed-breed dogs of5-7 months old and 12-14 kg BW were presented with hemorrhagic and protruded mass of bowel through anus. Clinical examination revealed intussusception with severe dehydration in the dogs, and there after ventral midline laparotomy was performed in both dogs which exposed and confirmed the cases as ileocolic intussusceptions. Results: The laparotomy was successful in both cases which involved certain level of intestinal resection and anastomosis. Postoperatively, the dogs were provided with adequate feed and necessary drugs; and successfully improved after 14 days of operation. Conclusion: Ileocolic intussusception in dogs can be successfully treated by urgent laparotomy with intestinal resection and anastomosis, which resumes the adequate potency and vitality of the bowel segments.
Highlights
Intussusception is known as a common cause of mechanical obstruction of intestine in dogs (Singh et al, 2015) that causes invagination of a portion of intestine called intussusceptum into the lumen of an adjacent intestinal segment (GarciaSancho et al, 2012) called intussuscipiens in the direction of normal peristalsis or occasionally in a retrograde direction (Rallis et al, 2000; Patsikas et al, 2003), and can restrict the blood flow to the trapped portion of tissue
It is believed that most intussusceptions in young animals are idiopathic, but several predisposing factors such as intestinal parasitism, linear foreign bodies, parvo-viral enteritis causing intestinal hypo or hypermotility, non-specific gastroenteritis, intraluminal masses, prior abdominal surgery, hypertrophied lymphoid nodules and granulomatosis secondary to inflammatory conditions may result in intussusception (Guilford and Strombeck, 1996; Rallis et al, 2000; Rewerts and Cohn, 2000; Patsikas et al, 2003, 2008; Schwandt, 2008; Allenspach, 2010; Gelberg, 2012)
Intussusception may be presented with the protrusion of segments of small intestine along with large intestine through the anus like a tubular mass (Rosin, 1985)
Summary
Intussusception is known as a common cause of mechanical obstruction of intestine in dogs (Singh et al, 2015) that causes invagination of a portion of intestine called intussusceptum into the lumen of an adjacent intestinal segment (GarciaSancho et al, 2012) called intussuscipiens in the direction of normal peristalsis or occasionally in a retrograde direction (Rallis et al, 2000; Patsikas et al, 2003), and can restrict the blood flow to the trapped portion of tissue. Clinical signs may vary with the amount of obstruction; in most cases the affected bowel may be palpable as a defined, firm and sausage (cylindrical) shaped intra-abdominal mass that must be differentiated from feces and foreign bodies (Butler, 1972; Larsen LH and Bellenger, 1974; Lewis DD and Ellison, 1987; Patsikas et al, 2003; Han et al, 2008).
