Abstract
Objectives: To describe the computed tomography appearance of gastropexy sites and report their anatomical and suspected functional abnormalities.
Materials and methods: Medical records of dogs with prior gastropexy undergoing abdominal computed tomography between December 2010 and June 2021 were reviewed from two veterinary hospitals. Dogs were categorised into two groups based on gastric anatomic distortion: anatomic (10) or non-anatomic (12).
Results: A total of 22 dogs were included, with time since gastropexy ranging from 16 to 1552 days (median: 311 days). Computed tomography findings showed a median attenuation of 38.5 HU (range: 6 to 57) of the gastropexy site, as well as focal slight thickening of the gastric wall and adjacent muscle in all dogs. Neovascularisation at the gastropexy site was found in approximately 65% of the animals, while marked gastric dilatation was noted in 32%, and a gravel sign was observed in 73%. The anatomic group had broader pedicles and a greater distance from the xiphisternum and midline compared to the non-anatomic group. Median gastric angles were significantly smaller in the gastropexy groups (Anatomic: 85.5°; Non-anatomic: 52°) compared to a control group (132°).
Clinical significance: The current study identified specific computed tomography imaging features of gastropexy sites contributing to a better understanding of the range of appearance and degree of detected anatomic distortion following gastropexy. It also identified signs of suspected gastric functional abnormalities in all gastropexy patients regardless of the degree of anatomic distortion.
期刊介绍：
Journal of Small Animal Practice (JSAP) is a monthly peer-reviewed publication integrating clinical research papers and case reports from international sources, covering all aspects of medicine and surgery relating to dogs, cats and other small animals. These papers facilitate the dissemination and implementation of new ideas and techniques relating to clinical veterinary practice, with the ultimate aim of promoting best practice. JSAP publishes high quality original articles, as well as other scientific and educational information. New developments are placed in perspective, encompassing new concepts and peer commentary. The target audience is veterinarians primarily engaged in the practise of small animal medicine and surgery.
In addition to original articles, JSAP will publish invited editorials (relating to a manuscript in the same issue or a topic of current interest), review articles, which provide in-depth discussion of important clinical issues, and other scientific and educational information from around the world.
The final decision on publication of a manuscript rests with the Editorial Board and ultimately with the Editor. All papers, regardless of type, represent the opinion of the authors and not necessarily that of the Editor, the Association or the Publisher.
The Journal of Small Animal Practice is published on behalf of the British Small Animal Veterinary Association and is also the official scientific journal of the World Small Animal Veterinary Association
