Repairment of perineal hernia by transposition of the internal obturator muscle was the objective of the study with respect to perioperative analgesia, the feature of the disease, used surgical techniques and clinical outcomes.
Seventeen intact male dogs in different age (7-13, mean 9,5 years old) and breed were subjected in the study. Rectal diverticulum with sacculation (n=6), rectal dilatation with severe pathology (n=2) and rectal sacculation (n=4) was the encountered disease concurrently with perineal hernia. While bilateral hernia was seen in 8 dogs, the rest was unilateral. The hernia was repaired by transposition of internal obturator muscle uni or bilaterally. Rectal resection was performed by dorsal perineal approach with inverted U shaped incision in two dogs and rectal wall repairment by extraluminal serosal muscular interrupted sutures with 4/0 polyglactin 910 (Vicryl - Ethicon) in 8 dogs. Perioperative analgesia was achieved with epidural morphine before the operation in 10 dogs and the rest was conditioned as routine manner.
The analgesia was superior in epidurally applied morphine cases in postoperative 24th hours. There was no recurrence in any cases according to 2 month-2 year (mean 12.8 month) observation period.
