To compare simple closure and polytetraflouroethylene (PTFE) patch methods in rectovaginal fistula repair in dog as an animal model, 16 mixed-bred female dogs weighing 20–35 kg were enrolled. Under general anesthesia in lithotomy position, an iatrogenic rectovagina fistula was created 4 cm anterior to anal verge and 8 weeks after confirmation of fistula tract formation, the dogs were randomly divided into 3 groups. In group 1, with perineal approach, fistulectomy was performed and a 2x2 cm piece of PTFE patch was fixed in rectal side of the fistula; in group 2, after fistulectomy, the rectal side of the fistula was repaired with vicryl 3–0 interrupted stitches and in group 3, the catheter was removed from the fi...
