Biomechanical and Histological Evaluation of a Laparoscopic Stapled Gastropexy Technique in Dogs 总被引:1,自引:0,他引:1
ROBERT J. HARDIE DVM JAMES A. FLANDERS DVM Dipiomate ACVS PETER SCHMIDT BS KELLY M. CREDILLE DVM TOI P. PEDRICK DVM CHARLES E. SHORT DVM PhD Dipiomate ACVA 《Veterinary surgery : VS》1996,25(2):127-133
The biomechanical holding strength and histological characteristics of a laparoscopic stapled gastropexy (LG) adhesion were compared with that of an incisional gastropexy (IG) adhesion. An LG was performed in 14 dogs and an IG was performed in six dogs. During the LG procedure, the abdomen was insufflated with carbon dioxide and three cannulae were placed in the caudal aspect of the right side of the abdomen. A 35 mm laparoscopic stapler was used to staple the gastric antrum to the adjacent right lateral abdominal wall. The IG procedure was performed through a ventral midline celiotomy. A 35 mm IG was made by apposing the gastric antrum to the adjacent right lateral abdominal wall with two continuous rows of suture. Half of each group of dogs was euthanatized at 7 and 30 days after surgery. The mean tensile load to failure at 7 days was 44.86 ± 18.54 N for the LG group and 85.33 ± 23.59 N for the IG group ( P <.05). At 30 days the values were 72.93 ± 18.01 N for the LG group and 71.17 ± 12.11 N for the IG group ( P =.41). The gastropexy adhesions in the 7-day postoperative group contained variable amounts of fibrin, hemorrhage, mononuclear cell inflammation, loose fibrovascular tissue, and mature collagenous connective tissue. Adhesions in the 7-day postoperative group were divided subjectively into three histological subgroups based on the relative amounts of mature connective tissue within the adhesion. The LG and IG adhesions were randomly distributed among these subgroups ( P = 1.0). Adhesions in the 30-day postoperative group contained well-organized fibrous connective tissue. No difference in the amount of connective tissue could be detected histologically in the LG or IG adhesions. Complications with the LG procedure included stomach perforation (2 cases), splenic puncture (2 cases), and subcutaneous emphysema (4 cases). 相似文献

Copper toxicosis in Bedlington Terriers in the United Kingdom 总被引:1,自引:0,他引:1
This paper summarizes the clinical and laboratory data on two adult Bedlington Terriers with liver disease associated with copper toxicosis. The younger dog, at 3 years, had elevated serum levels of alanine aminotransferase and alkaline phosphatase with active parenchymal cell degeneration and hepatitis. The second dog developed chronic hepatic failure at 5 years with advanced cirrhosis. Both dogs had stainable copper granules in the liver and chemical analysis of their livers revealed elevated copper contents (1,027 and 10,728 μg/g dry weight; normal less than 300 μg/g). These are the first published cases of this inherited abnormality of copper metabolism in this breed in this country. 相似文献

Abstract. A disease of the vertebral column is described in three adult wild-caught Lates calcarifer (Bloch) from the Northern Territory, Australia. It is characterized by the deposition of bone in the intervertebral space thus fusing the vertebrae, and the development of a thick gelatinous mass of loose connective tissue around the affected part of the vertebral column. Though a Clostridium sp. was isolated from one fish, it was not thought to be the primary cause. 相似文献
