As an intern, I used to joke around with people who were interested in GI. I was hardcore cards. However, after looking after pt's admitted w/ GI problems, it really struck me as being interesting and gratifying. Pt's come in sick as all get out...bleeding, IBD, cholangitis, obstructions, etc. Typically w/ good care from all players (certainly not just GI), they leave pretty much the way they came in. Didn't seem so true in cards from my experience. Procedures are nice but I was not a huge procedure guy in residency. It turns out that GI is very intellectually stimulating w/ the variety to keep me interested. At least for me, screening colons are not all that fun. I'm probably wrong but I can't see med students or interns watching screening colons and thinking..Oh yeah baby...I want to do that for the rest of my career.
