Comparison of patient outcomes following enterotomy versus intestinal resection and anastomosis for treatment of intestinal foreign bodies in dogs.

OBJECTIVE: To quantify the relative risk of intestinal dehiscence in dogs undergoing intestinal resection and anastomosis (IRA), compared with enterotomy, for surgical management of small intestinal foreign bodies, and to evaluate the association between nasogastric tube placement for early enteral nutrition (EEN) and hospitalization time. ANIMALS: 211 dogs undergoing 227 surgeries for intestinal foreign body removal. PROCEDURES: Medical records were reviewed for dogs undergoing a single-site sutured enterotomy or IRA for foreign body intestinal obstruction between May 2008 and April 2018. Multivariable logistic regression was used to quantify the association between surgical procedure and dehiscence. Multiple linear regression was used to quantify the association of nasogastric tube placement with total hospitalization time. RESULTS: Dehiscence rates were 3.8% (7/183) and 18.2% (8/44) for enterotomy and IRA, respectively. Overall dehiscence rate for all surgeries was 6.6% (15/227). The odds of intestinal dehiscence for IRA were 6.09 times (95% CI, 1.89 to 19.58) the odds for enterotomy. An American Society of Anesthesiologists score > 3 (OR, 4.49; 95% CI, 1.43 to 14.11) and an older age (OR, 1.02 [95% CI, 1.01 to 1.02] for each 1-month increase in age) were significantly associated with greater odds of intestinal dehiscence, regardless of surgical procedure. Placement of a nasogastric tube was not associated with intestinal dehiscence or decreased total hospitalization time when controlling for the year of surgery. CONCLUSIONS AND CLINICAL RELEVANCE: Patients undergoing IRA were at a significantly higher risk of intestinal dehiscence, compared with patients undergoing enterotomy. Although this finding should not be used to recommend enterotomy over IRA, this information may be useful in guiding owner expectations and postoperative monitoring.

Fracture-associated osteosarcoma of the femur in a cat.

This report describes a domestic shorthair cat with fracture-associated osteosarcoma 11 years after injury. A left hind limb amputation was performed using coxofemoral disarticulation. No intravenous cytotoxic chemotherapy was used after surgery. Pulmonary metastasis was identified 3 months after amputation. Fracture-associated osteosarcoma may occur in the cat more than 10 years after initial injury.

Ostéosarcome du fémur associé à une fracture chez un chat. Ce rapport décrit un chat commun domestique atteint d'un ostéosarcome associé à une fracture 11 ans après la blessure. Une amputation du membre arrière gauche a été réalisée à l'aide de la désarticulation coxofémorale. Aucune chimiothérapie cytotoxique intraveineuse n'a été utilisée après la chirurgie. La métastase pulmonaire a été identifiée 3 mois après l'amputation. Un ostéosarcome associé à une fracture peut se produire chez le chat plus de 10 ans après la blessure initiale.(Traduit par Isabelle Vallières).

Prevalence of adrenal gland masses as incidental findings during abdominal computed tomography in dogs: 270 cases (2013-2014).

OBJECTIVE To determine the prevalence and clinical characteristics of incidental adrenal gland masses identified in dogs undergoing abdominal CT. DESIGN Retrospective case series. ANIMALS 270 client-owned dogs. PROCEDURES Medical records of dogs that underwent abdominal CT from June 2013 through June 2014 were reviewed. Patients were excluded if they had undergone CT because of a history or clinical signs of an adrenal gland mass or disease. Information collected included history, signalment, initial complaint, serum alkaline phosphatase activity, urine specific gravity, and whether abdominal ultrasonography was performed. Imaging reports generated by the board-certified radiologist who evaluated the CT images were reviewed. RESULTS Incidental adrenal gland masses were detected in 25 of the 270 (9.3%) dogs. Dogs with incidental adrenal gland masses were significantly older (median, 12.0 years; range, 8.0 to 15.0 years) than dogs without (8.2 years; range, 0.1 to 13.1 years). Dogs examined for neoplasia were significantly more likely to have an incidental adrenal gland mass (22/138 [15.9%]) than were dogs examined for any other reason (3/132 [2.3%]), but these dogs were also significantly older. No other risk factors were identified. Histologic examination was performed in only 3 of the 25 dogs with incidental adrenal gland masses; 2 had cortical adenomas and 1 had a pheochromocytoma and cortical adenoma. CONCLUSIONS AND CLINICAL RELEVANCE Results suggested that a clinically important percentage of dogs undergoing abdominal CT will have incidental adrenal gland masses, with incidental masses more likely in older than in younger dogs.
