Aerodigestive diseases (AeroD), hybrid disorders between the respiratory and gastrointestinal (GI) tracts, may present without GI signs. Sliding hiatal hernia (sHH) is an important AeroD in brachycephalic dogs linked to respiratory pathology. The spectrum of other AeroD and respiratory clinical signs (CS) in brachycephalic and nonbrachycephalic dogs with sHH is unknown.
Characterize CS of AeroD in dogs with sHH, compare CS between brachycephalic and nonbrachycephalic dogs, and compare thoracic radiographs and videofluoroscopic swallow study (VFSS) for diagnosing sHH.
Sixty-seven client-owned dogs with sHH.
Medical records of dogs with sHH presented to the veterinary teaching hospitals at Auburn University and the University of Missouri between 1 January 2009 and 31 December 2020 were retrospectively reviewed. Between group, comparisons were made using Mann-Whitney test, Chi-square analysis, and Spearman correlation (P < .05).
Dogs with sHH presented with exclusively GI signs (28/67), mixed respiratory and GI signs (22/67), or with exclusively respiratory signs (17/67). Wheras brachycephalic dogs were not significantly more likely to present with respiratory CS (P = .145), they were younger (P < .001), and more likely to present in respiratory distress (P = .02), and with radiographic evidence of aspiration pneumonia (P < .001) compared to nonbrachycephalic dogs. Six of 12 dogs with normal thoracic radiographs having sHH presented with respiratory CS. For detection of sHH, VFSS was superior to radiographs (P < .001).
Dogs with sHH may present with exclusively respiratory signs. Respiratory signs may be more severe in brachycephalic compared to nonbrachycephalic dogs. Videofluoroscopic swallow study was superior to thoracic radiographs for detection of sHH in dogs.
气消疾病（AeroD）是呼吸道和胃肠道（GI）之间的混合疾病，可能没有 GI 迹象。滑动性食管裂孔疝（sHH）是一种与呼吸病理学相关的短头犬的重要 AeroD。短头犬和非短头犬 sHH 患者的其他 AeroD 和呼吸临床症状（CS）的范围尚不清楚。
描述 sHH 犬的 AeroD CS，比较短头犬和非短头犬的 CS，比较胸部 X 线片和视频荧光吞咽研究（VFSS）诊断 sHH。
67 只患有 sHH 的患犬。
回顾性分析 2009 年 1 月 1 日至 2020 年 12 月 31 日期间在奥本大学和密苏里大学兽医教学医院就诊的患有 sHH 的犬的病历。使用 Mann-Whitney 检验、卡方分析和斯皮尔曼相关性进行组间比较（P < .05）。
患有 sHH 的犬表现为单纯的 GI 症状（28/67）、混合性呼吸和 GI 症状（22/67）或单纯的呼吸症状（17/67）。尽管短头犬出现呼吸 CS 的可能性没有显著增加（P = .145），但它们更年轻（P < .001），更有可能出现呼吸窘迫（P = .02），并且更有可能出现放射性吸入性肺炎（P < .001）与非短头犬相比。12 只胸部 X 线片正常的 sHH 犬中有 6 只出现呼吸 CS。对于 sHH 的检测，VFSS 优于 X 线片（P < .001）。
患有 sHH 的犬可能表现为单纯的呼吸症状。与非短头犬相比，短头犬的呼吸症状可能更严重。VFSS 对于检测犬的 sHH 优于胸部 X 线片。
