Abstract
Case Description—An adult sexually intact female Vietnamese potbellied pig was examined because of abdominal distention of 5 months' duration.
Clinical Findings—The pig was moderately anemic, and its abdomen was greatly distended. A freely movable abdominal mass was detected during palpation and ultrasonographic examination of the abdomen. Examination of abdominal and thoracic radiographs revealed faint, ill-defined, linear and curvilinear mineralized opacities in the region of the mass and that the gastrointestinal tract was displaced craniodorsally. Results of radiographic exami-nation suggested that the cause of distention was a single abdominal mass (possibly a neoplasm).
Treatment and Outcome—Surgery was performed, and the mass, which was identified as the right ovary, was removed. The left ovary had a normal appearance, but it was also removed during surgery. The pig was administered a transfusion (314 mL of plasma and 296 mL of packed RBCs) before and during surgery. The mass, which accounted for ap-proximately one-third of the pig's body weight, was identified histologically as an ovarian leiomyoma.
Clinical Relevance—Pigs can safely be administered a transfusion of RBCs and plasma. Ovarian tumors can be removed from Vietnamese potbellied pigs, which allows them to be used as pets or for reproduction when only 1 ovary is affected. Uterine masses in older sexually intact Vietnamese potbellied pigs are more common than are ovarian tumors; thus, complete ovariohysterectomy should be considered when the primary purpose of the pig is to serve as a pet.
Abstract
Objective—To compare clinical outcome, healing, and effect of tracheostomy in conventional incisional and carbon dioxide (CO2) laser techniques for resection of soft palates in brachycephalic dogs.
Design—Prospective randomized trial.
Animals—20 adult brachycephalic dogs.
Methods—Dogs were randomly allocated into 4 groups, and 1 of the following was performed: palate resection by use of a CO2 laser; incisional palate resection and closure with suture; and palate resection by use of a CO2 laser or incision with tracheostomy. A clinical score for respiratory function was assigned to each dog at 0, 2, 8, 16, and 24 hours. Biopsy specimens of incision sites obtained at days 0, 3, 7, and 14 were examined. Data were analyzed to determine the effects of technique on clinical and histologic outcome.
Results—Mean surgical time for laser (309 seconds) was significantly shorter than for sharp dissection (744 seconds). Surgical technique significantly affected clinical scores at 3 of the 5 postoperative time points, but differences were not clinically apparent. Tracheostomy significantly affected clinical scores at 3 of 5 postoperative time points. After tracheostomy tube removal, clinical scores were similar to those of dogs without tracheostomies. Inflammation, necrosis, and ulceration were evident in all groups at day 3; these lesions had almost resolved by day 14. Most complications were associated with tracheostomy.
Conclusions and Clinical Relevance—Clinical outcomes appear to be similar with the laser and incisional techniques. Regarding surgical time and ease, laser resection of the soft palate appears advantageous. Tracheostomy is not warranted in dogs that have uncomplicated surgeries and recoveries.
