Abstract:This question introduces the resection of giant vaginal tumor in pet dogs and the followup treatment process. Because the tumor is too large, it is not suitable for surgical resection of the vulva. In the absence of minimally invasive surgery, ventral and dorsal incisions were made to avoid large blood vessels, nerves, rectum, urethra, etc., and the vagina was exposed. The vagina was pulled out of the body with ring forceps, the vagina was incised, and ring tumor resection was performed. The dog is currently in good condition. This article aims to provide a reference for the clinical treatment of this disease.
