A 17 wk old sexually intact female domestic shorthair kitten presented for an anogenital cleft and enlarged colon. The cat had experienced bacterial cystitis and constipation since weaning. Contrast referral images revealed an enlarged colon with a patent anus. Clinical examination revealed an anogenital cleft with a common anovulvar orifice. The rectum was patent upon digital rectal palpation, and fecal contamination of the vulva was present. Abdominal radiographs revealed two distinct colons, both filled with a moderate amount of formed fecal material. Contrast-enhanced computed tomography revealed segmental duplication of the descending colon with a dominant right colon and a smaller accessary left colon. The two structures conjoined at the transverse colon proximally and at the pubic brim distally. A common anogenital orifice with anovulvar communication was also noted. The anogenital cleft malformation was successfully repaired surgically. A celiotomy was performed to remove the smaller accessory colon. An ovariectomy and partial hysterectomy were also performed. The patient recovered uneventfully and showed no gross evidence of recurrent cystitis or urinary or fecal incontinence postoperatively. This is believed to be the first report of a congenital anogenital cleft and complete communicating colonic duplication in a cat.
一只17周龄性成熟的雌性家养短毛小猫因肛门生殖器裂和结肠扩张前来就诊。这只猫自断奶后就一直患有细菌性膀胱炎和便秘。对比转诊影像显示结肠扩张且肛门通畅。临床检查发现有肛门生殖器裂，伴有共同的肛门外阴口。直肠指检时直肠通畅，外阴有粪便污染。腹部X光片显示有两个不同的结肠，均充满适量的成形粪便。增强CT显示降结肠节段性重复，右侧结肠为主，左侧有较小的副结肠。这两个结构在近端横结肠处相连，在远端耻骨联合处相连。还发现有共同的肛门生殖器口且肛门与外阴相通。肛门生殖器裂畸形通过手术成功修复。进行剖腹术以切除较小的副结肠。还进行了卵巢切除术和部分子宫切除术。患者恢复顺利，术后未发现复发性膀胱炎或尿失禁或大便失禁的明显迹象。据信这是关于猫先天性肛门生殖器裂和完全连通性结肠重复的首例报告。
