BACKGROUND Ileoscopy is increasingly performed in dogs and cats with gastrointestinal signs, but iatrogenic ileocecocolic (ICC) perforations have not been described. HYPOTHESIS/OBJECTIVES To characterize endoscopic ICC perforations in dogs and cats. ANIMALS Thirteen dogs and 2 cats. METHODS This is a retrospective case series. Signalment, presentation, endoscopic equipment, colonic preparation, endoscopist's experience level, ileal intubation technique, method of diagnosis, perforation location, histopathology, management, and outcome data were collected and reviewed. RESULTS Six ileal, 5 cecal, and 4 colonic perforations were identified between 2012 and 2019. Dogs weighed 2.4-26 kg (median, 10.3 kg) and cats 4.6-5.1 kg (median, 4.9 kg). Endoscopy was performed in dogs presented for vomiting (n = 4), as well as large (n = 5), mixed (n = 4), and small (n = 1) bowel diarrhea. Cats had large bowel diarrhea. Endoscopists included 1 supervised intern, 9 supervised internal medicine residents (2 first year, 6 second year, 1 third year), and 5 internal medicine diplomates. Diagnosis was delayed in 5 dogs, occurring 1-5 days after endoscopy (median, 3 days); dogs were presented again with inappetence (n = 4), lethargy (n = 4), abdominal pain (n = 3), retching (n = 2), and syncope (n = 1). All animals underwent surgical correction. Histopathology did not identify lesions at the perforation site in any animal. Two dogs required a second surgery; 1 died 12 hours after surgery. Survival to discharge was 93%, with 78% surviving ≥8 months. CONCLUSIONS AND CLINICAL IMPORTANCE Iatrogenic endoscopic ICC perforation is not indicative of underlying disease and is associated with a good prognosis. Delayed diagnosis can occur. Therefore, perforation should be considered in the differential diagnosis for animals with clinical deterioration after endoscopy.

对狗和猫的诊断性下消化道内窥镜检查相关的回肠球菌穿孔进行多中心回顾性评估。

背景技术在具有胃肠道体征的狗和猫中越来越多地进行肠镜检查，但是尚未描述医源性回肠球菌（ICC）穿孔。假设/目的表征猫和狗的内镜ICC穿孔。动物十三只狗和两只猫。方法这是一个回顾性病例系列。收集并审查信号，表现，内窥镜设备，结肠准备，内窥镜医师的经验水平，回肠插管技术，诊断方法，穿孔位置，组织病理学，管理和结果数据。结果在2012年至2019年期间，发现了6个回肠，5个盲肠和4个结肠穿孔。狗的体重为2.4-26千克（中位数为10.3千克），猫的体重为4.6-5.1千克（中位数为4.9千克）。对出现呕吐的狗（n = 4），大型（n = 5），混合（n = 4）的狗进行内窥镜检查，小肠（n = 1）。猫大肠腹泻。内镜医师包括1名受监督的实习生，9名受监督的内科医师住院医师（第一年2名，第二年6名，第三年1名），以及5名内部医学外交官。5只狗的诊断被延迟，发生在内窥镜检查后1-5天（中位数为3天）。犬再次出现食欲不振（n = 4），嗜睡（n = 4），腹痛（n = 3），呕吐（n = 2）和晕厥（n = 1）。所有动物均接受外科手术矫正。组织病理学未发现任何动物的穿孔部位的病变。两只狗需要第二次手术。术后12小时死亡1例。出院生存率为93％，≥8个月生存率为78％。结论和临床意义医源性内镜ICC穿孔不能预示潜在疾病，并且预后良好。可能会延迟诊断。因此，在内镜检查后临床恶化的动物的鉴别诊断中应考虑穿孔。
