Ravi Kiran. He was at the Cleveland Clinic & is now at Columbia. He's an expert at k-Pouch construction as well as J-Pouch & revisions. I was referred to him by another Cleveland Clinic alum. I also considered Dr. Hull. I've seen her lecture a few times and she is impressive.
I had a great 2- part surgery with Dr. Kiran. One of the many benefits of Columbia is that when I started with floppy pouch issues, I was quickly set up under the care of Dr Shen.
