Arthroscopy-Assisted Minimally Invasive Harvest of Fascia Lata for Revision Repair of Perineal Hernia in a Dog

초록

Perineal hernia is a common surgical problem in old male dogs and usually presents a high risk of recurrence, particularly after a failed repair. This article describes the use of arthroscopy-assisted fascia lata (FL) for repair of perineal hernia after tunica vaginalis graft failure in a dog. A 10-year-old intact male Pomeranian was examined with left perineal swelling and dyschezia. Imaging suggested a left perineal hernia accompanied by prostatic enlargement. Herniorrhaphy using a tunica vaginalis graft was initially performed, and the postoperative infection resulted in graft dehiscence. Revision surgery involved anal sacculectomy, debridement, and repair, using a FL graft harvested using an arthroscopy-assisted technique. The dog recovered uneventfully, with physiological hematological parameters and no recurrence, infection, or donor-site morbidity were recorded at the 2-month follow-up. This case highlights the feasibility and clinical application of minimally invasive FL harvesting in dogs, which can be a useful alternative for conventional open technique of graft harvest with low donor-site complications.
