Background: The change in size and weight of the female reproductive organs during gestation and birth might be affect the perineal muscles and this condition in dairy cow not been reported. This study aimed to assess the ultrasonographic image of coccygeus muscle in 11 inseminated dairy cows with different gestational ages and postpartum. Methods: Gestational age was calculated based on the record of artificial insemination and confirmed by using transrectal brightness mode ultrasonography. Perineal hair between the sacrum and ischium bones was shaved along 3-5 cm before being ultrasound. The images of perineal area were obtained by transcutaneous ultrasound using a 5.0 MHz transducer. The thickness and intensity of the coccygeus muscle were measured and analyzed by gestational status and postpartum to show the differences. Results: The results showed that the thickness of coccygeus muscle increased with the increase in gestational age. Muscle intensity only increased at young gestational age. However, it decreased with the increase in gestational age (P < 0.05). Conclusions: The ultrasound image of coccygeus muscle was affected by gestational status, thus this method may be used as one of the new methods of indirect gestational detection on dairy cows.

A 4-year-old intact female Maltese was referred to the Animal Medical Center of Chonbuk National University with a history of consistent fecal incontinence over 4 months following sacculectomy surgery. We suspected that anal sacculectomy resulted in loss of the external anal sphincter. On physical examination, the external anal sphincter muscle on the left side was intact, while the external anal sphincter muscle on the right side could not be detected and exhibited severe laceration. To repair the defect, the left semitendinosus muscle was transposed around the anus. The left semitendinosus muscle was isolated and transected near the stifle, reflected dorsally and passed around the ventral rectum into the pararectal fossa. Care was taken to preserve the integrity of the vasculature and nerve supply. The muscle was secured dorsally with simple interrupted sutures to the levator ani and coccygeus muscles to simulate the external anal sphincter. Nine days after surgery, the dog was defecating normally with no evidence of incontinence. The use of semitendinosus muscle flaps is a good option for the treatment of fecal incontinence secondary to loss of sphincter muscle in dogs.

Perineal hernia occurs spontaneously in older male dogs after idiopathic weakening of the pelvic diaphragm A 14-year-old uncastrated male shih tzu dog with right-sided perineal swelling was referred to the Veterinary Medical Teaching Hospital of Konkuk University. He had sign of perineal swelling for three years. Plain radiography documented the extent of rectal and colonic dilation in the herinal sac. During surgery, external anal sphincter muscle, coccygeus muscle and levator am muscle were weakened due to the three years of herniation. Internal obturator muscle transposition method was not enough for large defect, so mesh was applied to reduce the hernial sac. Internal obturator muscle transposition combined with using of polypropylene mesh was successfully performed in this dog.
