In an effort to reduce shelter intake, Miami-Dade Animal Services (MDAS) Pet Retention Program offers caretakers with an opportunity to have animals treated for certain medical conditions, free of charge. Discovery of new, simple surgical techniques for low-cost procedures provides veterinarians with more surgical solutions, expands the capacity for services provided through low-cost veterinary clinics and other shelter programs, and provides shelters with life-saving alternatives that will increase adoptability of homeless pets and reduce euthanasia rates. The aim of this clinical trial was to describe and to evaluate the use of the autologous tunica vaginalis communis as a free graft to repair perineal hernia (PH) in intact male dogs at an animal shelter facility. In 2018, seven male intact dogs, diagnosed with perineal hernias (PH), were presented to MDAS. All dogs had the surgical reconstruction of the pelvic diaphragm repaired by using the tunica vaginalis communis obtained at the time of castration, prior to the perineal access, and sutured directly into the perineal defect. Clinical outcome including postoperative complications and hernia recurrence were obtained via telephone communication. The median follow-up time was 13 months. None of the dogs included in this study had recurrence of the PH. All dogs were adopted, were transferred to animal rescue organizations or were returned to their owners after the surgical procedure. The use of tunica vaginalis communis autograft is a simple, low-cost surgical technique that requires less surgical expertise and training and can be used for perineal herniorrhaphy in dogs, without long-term recurrence.
