A randomized, blinded, placebo-controlled, prospective clinical study to evaluate the effectiveness of a diluted liposomal-encapsulated bupivacaine suspension in dogs undergoing a ventral midline celiotomy.

Objective: To evaluate the effectiveness of a liposomal-encapsulated bupivacaine suspension (LEBS; Nocita), at a 1:5 dilution with 0.9% NaCl, for the reduction of postoperative pain scores and a related reduction in the need for postoperative opioids in dogs undergoing ventral midline celiotomy.

Hypothesis: When infused at a 1:5 dilution, LEBS results in less postoperative pain (as indicated by pain scale scores), and a reduction in postoperative opioids, in dogs undergoing ventral midline celiotomy.

Consequences of intratumoral injection of a herbal preparation containing blood root (Sanguinaria canadensis) extract in two dogs.

Case Description: 2 dogs were referred for surgical removal of cutaneous tumors that had previously been treated by intratumoral injection of a herbal preparation containing blood-root (Sanguinaria canadensis) extract.

Clinical Findings: 11 days following injection of bloodroot extract into a small dermal tumor, dog 1 developed a large, soft, fluctuant cutaneous mass at the site of injection. Ultrasonographic evaluation of the mass revealed a fluid-filled central cavity with increased echogenicity of the surrounding subcutaneous tissues.

Study Design: Clinical report.

Animals: Two-year-old male Labrador retriever.

Evaluation of the learning curve for natural orifice transluminal endoscopic surgery: bilateral ovariectomy in dogs.

Objective: Study the learning curve for canine Natural Orifice Transluminal Endoscopic Surgery (NOTES) ovariectomy by evaluating operative times and complications.

Study Design: Preclinical research study.

Animals: Adult female dogs (n=20).

Mucinous gastric carcinoma with abdominal carcinomatosis and hypergastrinemia in a dog.

A 12-year-old, spayed female Australian cattle dog was evaluated for a 5-month history of progressive vomiting. Abdominal radiographs and ultrasound revealed significant gastric wall thickening and a peripancreatic mass, and serum gastrin concentration was increased (127 pg/mL, reference range 10 to 40 pg/mL). Surgical exploration of the abdomen revealed a thickened, firm, and irregular gastric fundus, pylorus, and antrum; nodules were present throughout the spleen and mesentery adjacent to the left limb of the pancreas.
