Postoperative ultrasonographic appearance of uncomplicated enterotomy or enterectomy sites in dogs

abstract: The ultrasonographic findings in 20 dogs with 25 healing enterotomy and enterectomy sites resulting from the removal of foreign material or correction of intussusceptions are presented. In this prospective study, dogs had preoperative abdominal ultrasound examinations followed by sequential sonographic examinations on the first, third, sixth, and 10th days postenterotomy or enterectomy with an additional sonographic examination after 20 days postoperatively. Documented sonographic features included length and maximal intestinal wall thickness of the enterotomy or enterectomy sites, echogenicity of omental/mesenteric fat, amount of free gas and abdominal effusion, and gastrointestinal motility. Sonographically, 57% of enterotomies and 100% of enterectomies were visualized. Pneumoperitoneum, hyperechoic omental/mesenteric fat, and abdominal effusion did not appreciably hamper evaluation of the intestinal surgical site. Absent wall layering at the surgical site was noted in 96% of dogs at day 1 postoperatively. At the final sonographic examination, wall layering remained altered to absent in 100% of dogs and normal thickness was noted in only 20% of dogs. The median maximal wall thickness was 7 and 8 mm for enterotomies and enterectomies respectively, which occurred between days 1 and 3 and days 3 and 6 postoperatively. Effusion and increased echogenicity of omental/mesenteric fat localized to the surgical site were noted in 42% and 60% of dogs respectively at day 1 postoperatively, with resolution noted between days 3 and 10 postoperatively in 92% and 80% of dogs. Generalized abdominal effusion and pneumoperitoneum were seen in 100% of dogs immediately postoperatively and resolved in 80% by day 10

ACVIM consensus statement on the diagnosis and treatment of chronic hepatitis in dogs

Abstract This consensus statement on chronic hepatitis (CH) in dogs is based on the expert opinion of 7 specialists with extensive experience in diagnosing, treating, and conducting clinical research in hepatology in dogs. It was generated from expert opinion and information gathered from searching of PubMed for manuscripts on CH, the Veterinary Information Network for abstracts and conference proceeding from annual meetings of the American College of Veterinary Medicine and the European College of Veterinary Medicine, and selected manuscripts from the human literature on CH. The panel recognizes that the diagnosis and treatment of CH in the dog is a complex process that requires integration of clinical presentation with clinical pathology, diagnostic imaging, and hepatic biopsy. Essential to this process is an index of suspicion for CH, knowledge of how to best collect tissue samples, access to a pathologist with experience in assessing hepatic histopathology, knowledge of reasonable medical interventions, and a strategy for monitoring treatment response and complications
