一个6岁被阉割的孩子,混合品种的猫出现呕吐,厌食症,和嗜睡。超声和计算机断层扫描显示圆形,边缘良好的结构与回肠交界处近端的回肠密切相关。剖腹探查术显示一个源自回肠远端的肿块,靠近回结肠交界处。肿块不与肠腔相互作用。在没有小肠切除的情况下进行了切除活检,以保留回肠结。组织病理学检查证实存在肠重复囊肿。猫从手术中恢复顺利,术后无症状。术后4个月无复发。肠重复囊肿是起源于胃肠道的罕见先天性异常。它们可以与肠腔连通或不连通。肠重复囊肿可以是有症状的或无症状的。与食管相关的肠重复囊肿,十二指肠,和空肠也有报道在猫。然而,据我们所知,这是首例报道的猫回肠肠重复囊肿。因此,肠重复应视为回肠囊性肿块的鉴别诊断。
A 6-year-old castrated, mixed breed cat presented with vomiting, anorexia, and lethargy. Ultrasonography and computed tomography revealed a round, well-marginated structure closely associated with the ileum proximal to the ileocolic junction. Exploratory laparotomy revealed a mass originating from the distal end of the ileum, close to the ileocolic junction. The mass did not interact with the intestinal lumen. Excisional biopsy with omentalization was performed without small intestinal resection to preserve the ileocolic junctions. Histopathological examination confirmed the presence of an enteric duplication cyst. The cat recovered uneventfully from surgery and remained asymptomatic postoperatively. No recurrence was identified 4 months after surgery. Enteric duplication cysts are uncommon congenital anomalies that originate in the gastrointestinal tract. They could either be communicating or non-communicating with the intestinal lumen. Enteric duplication cysts can be symptomatic or asymptomatic. Enteric duplication cysts associated with the esophagus, duodenum, and jejunum have also been reported in cats. However, to the best of our knowledge, this is the first reported case of an enteric duplication cyst in the feline ileum. Thus, enteric duplication should be considered a differential diagnosis in cystic masses of the ileum.
