It is hard to say that the BCIR is 'better' than a K-pouch. They are basically the same. What sets the BCIR apart from the standard K-pouch is the way the valve is constructed. The BCIR valve uses a small segment of intestine that 'wraps' around the base of the valve. This segment 'communicates' with the pouch. In other words, as the pouch fills with fecal matter, this segment fills and tightens a bit and supports the base of the valve - keeping it from bending, so to speak. According to their literature, this lessens the chance of the valve slipping which can result in leakage. BCIR valves do leak at times. But they probably leak less than a traditional Koch pouch. Susan Kay can send you literature about their procedure. Also, they hold seminars around the country. The surgeon usually attends these seminars to answer any questions.
