Oesophageal foreign bodies are common in dogs. Endoscopic removal is a viable treatment option but few studies have assessed the clinical and radiographic features that would be useful in decision-making and prognosis.Dogs (n = 44) with oesophageal foreign bodies presented to the University Veterinary Hospital were assessed. Terriers and West Highland White Terriers were significantly overrepresented (p < 0.0001) and in those breeds the foreign body was significantly (p < 0.0001) more likely to be located caudal to the heart base. The majority (88.6%) of foreign bodies were bones or bone fragments.Group 1 (n = 30) included animals where endoscopic removal was successful and Group 2 (n = 14) animals where it was unsuccessful or not attempted because of evidence of oesophageal rupture. There was no statistically significant difference in age, sex, body weight, type, location and size of foreign body, recovery rate, short-term complications and long-term outcome between the two groups. Duration of signs prior to presentation and time to spontaneous oral feeding were significantly longer (p < 0.01 in each case) in Group 2 (five days and 120 hours, respectively) compared to Group 1 (2 days and 24 hours, respectively). Mortality was 11.1%. Long-term follow-up of 29 dogs suggested oesophageal stricture formation manageable by feeding alone in seven (24.1%) cases.Terriers appear predisposed to oesophageal foreign bodies. Success of endoscopic removal is adversely affected by duration of signs prior to presentation. Surgical removal negatively influences time to recovery. Stricture formation appears to be a relatively common complication and alternate measures for its prevention should be sought.
食管异物在犬中很常见。内镜取出是一种可行的治疗选择，但很少有研究评估有助于决策和预后的临床和影像学特征。对到大学兽医医院就诊的患有食管异物的犬（n=44）进行了评估。梗犬和西部高地白梗的比例明显过高（p＜0.0001），并且在这些品种中，异物更有可能位于心脏基部的后方（p＜0.0001）。大多数（88.6%）异物为骨头或骨碎片。第 1 组（n=30）包括内镜取出成功的动物，第 2 组（n=14）包括内镜取出不成功或因食管破裂证据而未尝试的动物。两组之间在年龄、性别、体重、异物类型、位置和大小、回收率、短期并发症和长期预后方面没有统计学上的显著差异。第 2 组（分别为 5 天和 120 小时）与第 1 组（分别为 2 天和 24 小时）相比，在就诊前出现症状的时间和自主口服进食的时间明显更长（p＜0.01）。死亡率为 11.1%。对 29 只犬的长期随访表明，7 只（24.1%）犬因食管狭窄形成可通过单独喂养来控制，7 只（24.1%）犬因食管狭窄形成可通过单独喂养来控制。梗犬似乎易患食管异物。内镜取出的成功率受到就诊前出现症状的时间的影响。手术切除会对恢复时间产生负面影响。狭窄形成似乎是一种相对常见的并发症，应寻求其他预防措施。
