Shortening of the colon has been described in cats, but its imaging and clinicopathological features remain poorly understood.
Description of the signalment, clinical presentation, imaging, endoscopic and histological features of short colon syndrome in cats.
Ninety-three cats diagnosed with short colon.
Multi-institutional, descriptive, retrospective case series study. Medical records were searched for a diagnosis of short colon on abdominal ultrasonography, computed tomography, endoscopy, autopsy, or a combination of these modalities.
The median age of included cats was 12 years at the time of diagnosis. Diarrhea was the most common clinical sign (60/92; 65%), followed by vomiting (36/92; 39%), weight loss (36/92; 39%), and inappetence (24/92; 26%). Thirteen percent of cats (12/92) had no signs of gastrointestinal disease at the time of diagnosis. In addition to a shortened colonic length, 79% (66/84) of cats had concomitant colonic thickening on ultrasonographic examination. On colonoscopy, mucosal ulcerations of the colonic wall were seen in 39% (9/23) of cats. Histopathologically, all cats but 1 (diagnosed simultaneously with colonic small cell lymphoma) had lymphoplasmacytic colitis, and when small intestinal biopsies were performed, concurrent lymphoplasmacytic enteritis or small cell lymphoma of the small intestine.
Lymphoplasmacytic colitis is seen commonly in cats with short colon, suggesting a potential link between these entities.
猫的结肠缩短已有描述，但对其影像学和临床病理特征仍了解甚少。
描述猫短结肠综合征的一般情况、临床表现、影像学、内镜和组织学特征。
93 只被诊断为短结肠的猫。
多机构、描述性、回顾性病例系列研究。对腹部超声、计算机断层扫描、内镜、尸检或这些方式联合诊断为短结肠的猫的病历进行了检索。
纳入猫的中位年龄为诊断时 12 岁。最常见的临床症状是腹泻（60/92；65%），其次是呕吐（36/92；39%）、体重减轻（36/92；39%）和食欲不振（24/92；26%）。13%（12/92）的猫在诊断时没有胃肠道疾病的迹象。除了结肠长度缩短外，84%（66/84）的猫在超声检查时还伴有结肠增厚。在结肠镜检查中，39%（9/23）的猫可见结肠壁黏膜溃疡。组织病理学上，除 1 只猫（同时诊断为结肠小细胞淋巴瘤）外，所有猫均有淋巴浆细胞性结肠炎，且当进行小肠活检时，并发有淋巴浆细胞性肠炎或小肠小细胞淋巴瘤。
猫的淋巴浆细胞性结肠炎常见于短结肠，提示两者之间可能存在关联。
