That is a narrowing of the colon due to the infection of the diverticular that don't cause any problems unless they get infected. this is probably what happened with pope francis. the vatican seemed to have down played a little bit this surgery. even the fact he is going to the hospital for surgery is big news because he's 84 years old. we didn't know anything about it. the nbc news medical team tells me that is the surgery to remove the diverticulosis. he is the pope, of course, that could potentially lead to complications. >> claudio, thank you for jumping in on this breaking news.
