To present findings from a case series of gastric dilatation (GD) or gastric dilatation and volvulus (GDV) in working farm dogs in New Zealand that were examined at veterinary clinics, and to identify possible risk factors for GD or GDV in working farm dogs in New Zealand using a case-control study.
This retrospective study included a case-series and a case-control study. The case series analysed information from 62 case records of GD or GDV in working farm dogs seen between August 2004 and September 2009 at 13 veterinary clinics throughout New Zealand. Cases were classified as GD or GDV if the diagnosis was confirmed by radiography, surgery or post-mortem examination. Details of history and treatment, as well as outcomes, were obtained for each case. For the case-control study, records of 41 working farm dogs with GD or GDV (cases) seen between April 2008 and April 2009, and 82 working farm dogs examined because of trauma over the same period and in the same 13 clinics (controls), were used to model the risk factors for GD or GDV.
From the case-series study, 40/62 (65%) cases of GD or GDV that were examined and treated at the veterinary clinics returned to work. Of the 41 dogs where the gastric contents were recorded, 25 (61%) had predominantly food or bones in the stomach, and 26/27 dogs had a history of having eaten meat, bones or scavenged a carcass. The case-control study showed that the significant risk factors for GD or GDV, compared with control dogs presenting with trauma, were breed, age and season. The odds that a case of GD or GDV was a Huntaway, after adjusting for age and season, was 19 times higher than the odds a control was a Huntaway. Gender and bodyweight were not identified as risk factors.
A high proportion of farm working dogs with GD or GDV were successfully treated by veterinarians. The risk of a case of GD or GDV being a Huntaway was significantly higher than for a dog presenting as a trauma case. However the influences of the season of the year, climatic factors and nutritional factors on the pathogenesis need to be identified before adequate preventative measures can be recommended.
呈现新西兰工作农场犬在兽医诊所接受检查的胃扩张（GD）或胃扩张伴扭转（GDV）病例系列的研究结果，并通过病例对照研究确定新西兰工作农场犬发生GD或GDV的可能风险因素。
这项回顾性研究包括病例系列研究和病例对照研究。病例系列分析了2004年8月至2009年9月期间在新西兰13家兽医诊所就诊的62例工作农场犬GD或GDV病例记录。如果通过X线摄影、手术或尸检确诊，则将病例分类为GD或GDV。获取了每个病例的病史、治疗细节以及预后情况。对于病例对照研究，使用了2008年4月至2009年4月期间在同一13家诊所就诊的41例患有GD或GDV的工作农场犬（病例）以及同期因外伤接受检查的82例工作农场犬（对照）的记录，以模拟GD或GDV的风险因素。
从病例系列研究来看，在兽医诊所接受检查和治疗的62例GD或GDV病例中，40例（65%）恢复了工作。在记录了胃内容物的41只犬中，25只（61%）胃内主要是食物或骨头，并且27只犬中有26只曾有吃肉、啃骨头或 scavenged a carcass的病史。病例对照研究表明，与因外伤就诊的对照犬相比，GD或GDV的显著风险因素是品种、年龄和季节。在调整年龄和季节后，一例GD或GDV是汉塔威犬的几率比对照犬是汉塔威犬的几率高19倍。性别和体重未被确定为风险因素。
兽医成功治疗了很大比例患有GD或GDV的农场工作犬。一例GD或GDV是汉塔威犬的风险显著高于作为外伤病例就诊的犬。然而，在能够推荐适当的预防措施之前，需要确定一年中的季节、气候因素和营养因素对发病机制的影响。
