Partial volvulus, entrapment, and extraluminal obstruction of the jejunum in a cat.

A 2-year-old, spayed female, domestic shorthair cat was presented in compensated hypovolemic shock after 24 h of anorexia, vomiting, and lethargy. An enterotomy had been performed at 9 mo of age to remove a foreign body. Due to inconclusive findings on abdominal imaging, an exploratory laparotomy was done. An adhesion at the root of the mesentery, likely associated with the previous surgery, had resulted in partial volvulus, entrapment, and extraluminal obstruction of the jejunum. Transection of the adhesion allowed repositioning of the bowel without the need for resection. The cat was discharged from the hospital 7 d postoperatively. Adhesions have not previously been reported to cause small bowel volvulus in cats. Key clinical message: Abdominal adhesions as a cause of clinical disease in cats have apparently not been reported. This case report demonstrates how malposition of the gastrointestinal tract, secondary to adhesions, should be included as a differential diagnosis for feline patients presenting with acute abdomens. Previous abdominal surgery is a risk factor for development of adhesions. This case emphasized the importance of Halsted's principles of surgery to reduce the risk of postoperative adhesions, even in species not predisposed to forming adhesions.
