PURPOSE: This was the rational and the aim of the present investigation. Artificial silicone coated sphincters were implanted in dog’s colostomies. It was analyzed the continence for solid and liquid stools as well as the complications from these surgical procedures. METHODS: It was used 13 mongrel dogs, eleven males and two females, weights from 16 to 30kg ( 22.5 + 4.3kg ). Terminal colostomies were made using the C C - Silimed® devices, which were activated for an eight-hour periods. The animals were observed for 15 weeks. RESULTS: Fecal continence was proved by barium enema. The pressure in the system varied from 60 to 80cm of water ( 74.8 + 5.0cm ). The liquid volume inserted in the reservoir varied from 5 to 8ml ( 6.9 + 0.8ml ). Fecal continence was obtained in all animals, however, there was an eventual soiling when abdominal pressure was raised. Wound infection occurs in three dogs ( 23.1% ) and intestinal obstruction in one ( 7.7% ). CONCLUSION: The silicone artificial sphincter ( C C - Silimed® ) was effective for obtaining continence for solid and liquid stools. The results of this investigation give support to the future use of this sphincter in human patients with definitive colostomy.
