The clinical signs of 29 cats with ultrasonographic abnormalities at the ileocecocolic junction were reviewed. Twenty-eight cats had gastrointestinal signs, with acute vomiting and diarrhea being most prevalent. Eighteen of 29 cats had enlarged cecal lymph nodes. Focal hyperechoic mesenteric fat was noted in 18 of 29 cats, and mild focal fluid accumulation was seen in seven of 29 cats. Six cats had a round cecum, and eight cats had cecal content. The cecal wall was thickened in 19 cats, and the ileal wall was mildly thickened in six cats. Three cats had changes involving the ascending colon adjacent to the ileocecocolic junction. Fourteen cats had no ultrasonographic evidence of changes in the remainder of the gastrointestinal tract, and 13 of these 14 cats were symptomatic for gastrointestinal disease. Four cats with resolution of the ultrasonographic changes also had resolution of clinical signs. These results suggest that ultrasonographic abnormalities at the level of the ileocecocolic junction in cats are clinically significant and are seen in cats with acute vomiting or diarrhea. Fine-needle aspirates and biopsies of the ileocecocolic area had a low diagnostic yield. When no other gastrointestinal abnormalities are detected, we therefore recommend follow-up ultrasound examinations of these patients.
回顾了29只在回盲结肠交界处存在超声异常的猫的临床体征。28只猫有胃肠道症状，其中急性呕吐和腹泻最为常见。29只猫中有18只盲肠淋巴结肿大。29只猫中有18只可见局灶性高回声肠系膜脂肪，29只猫中有7只可见轻度局灶性液体积聚。6只猫盲肠呈圆形，8只猫有盲肠内容物。19只猫盲肠壁增厚，6只猫回肠壁轻度增厚。3只猫在回盲结肠交界处附近的升结肠有改变。14只猫在胃肠道其余部位没有超声改变的证据，这14只猫中有13只存在胃肠道疾病症状。4只超声改变消失的猫临床体征也消失。这些结果表明，猫回盲结肠交界处的超声异常具有临床意义，在急性呕吐或腹泻的猫中可见。回盲结肠区域的细针抽吸和活检诊断率较低。因此，当未检测到其他胃肠道异常时，我们建议对这些患者进行超声随访检查。
