A 6-year-old, spayed female German shepherd crossbreed had a 6-month history of a draining fistula in the left flank. Fistulography demonstrated an enterocutaneous fistula. Surgery revealed a granuloma that was enveloping the left ureter and caudal mesenteric artery and adhering to multiple loops of bowel. The granuloma centered on a gauze sponge inadvertently retained at time of ovariohysterectomy. Retained surgical foreign bodies can be avoided, and their frequency is likely underestimated. Risk factors identified in human medicine include emergency surgery, changes in surgical procedure, and obesity. A foreign body should be considered a potential cause of draining tracts in veterinary patients.
一只6岁已绝育的德国牧羊犬杂交母犬，左侧胁腹有一个排液瘘管，病史长达6个月。瘘管造影显示为肠皮肤瘘。手术发现一个肉芽肿，该肉芽肿包绕左输尿管和肠系膜后动脉，并与多个肠袢粘连。肉芽肿以卵巢子宫切除术中意外遗留的一块纱布海绵为中心。手术中遗留的异物是可以避免的，而且其发生频率可能被低估了。在人类医学中确定的风险因素包括急诊手术、手术程序的改变和肥胖。在兽医患者中，异物应被视为排液道的潜在病因。
