colonoscopy

He is a very experienced and dedicated physcian. I have had two colonoscopies with Dr. Zai. My colon was torturous and it was difficult for him to advance the tube and required a lot of physical manipulation on his part. Took 1 hour to advance the scope to where it needed to go. He was in a sweater afterwards. How many MDs would work this hard? He straightened me out thats for sure. Thanks Dr. Zai!
