Laparoscopic ultrasonography identifies more liver lesions in dogs compared to transabdominal ultrasonography.
Objective: To describe the use of laparoscopic ultrasound (LUS) for evaluation of the liver in dogs with clinical liver disease and to compare the findings of LUS to transabdominal ultrasound (TUS).
Methods: 8 client-owned dogs presenting for laparoscopic liver biopsies due to clinical liver disease were enrolled. All dogs underwent TUS, and liver lesions were identified, localized, and quantified per presumed liver lobe. Laparoscopic examination and LUS of the liver were performed, and liver lesions were identified, localized, and quantified. Laparoscopic liver biopsies were obtained and submitted for histopathological analysis, copper analysis, and culture and susceptibility.
Results: The median time to perform hepatobiliary TUS was 10 minutes (IQR, 7.5 to 12 minutes), and the median time to perform LUS and laparoscopic examination of the liver was 19.5 minutes (IQR, 17.8 to 23.5 minutes). The number of lesions identified on LUS versus TUS was significantly different, with 5 dogs having an additional 28 lesions identified on LUS that were not found on TUS. The diameter of lesions identified on TUS and LUS ranged from 0.3 to 4.5 cm and 0.1 to 4.1 cm, respectively. In 2 dogs, LUS was used to guide the biopsy of liver lesions that were not grossly appreciable on laparoscopic examination.
Conclusions: LUS identifies more liver lesions compared to TUS and can be used to guide the biopsy of lesions that are not grossly appreciable laparoscopically.
Clinical relevance: LUS should be considered when staging patients with hepatobiliary neoplasia and may result in the identification of additional liver lesions missed on preoperative imaging.
期刊介绍：
The American Journal of Veterinary Research supports the collaborative exchange of information between researchers and clinicians by publishing novel research findings that bridge the gulf between basic research and clinical practice or that help to translate laboratory research and preclinical studies to the development of clinical trials and clinical practice. The journal welcomes submission of high-quality original studies and review articles in a wide range of scientific fields, including anatomy, anesthesiology, animal welfare, behavior, epidemiology, genetics, heredity, infectious disease, molecular biology, oncology, pharmacology, pathogenic mechanisms, physiology, surgery, theriogenology, toxicology, and vaccinology. Species of interest include production animals, companion animals, equids, exotic animals, birds, reptiles, and wild and marine animals. Reports of laboratory animal studies and studies involving the use of animals as experimental models of human diseases are considered only when the study results are of demonstrable benefit to the species used in the research or to another species of veterinary interest. Other fields of interest or animals species are not necessarily excluded from consideration, but such reports must focus on novel research findings. Submitted papers must make an original and substantial contribution to the veterinary medicine knowledge base; preliminary studies are not appropriate.
