I'm coming up on my Peds GI month. What do these subspecialists study from? Is there one book that fellows routinely read through during their first year of fellowship? Or does everyone learn from an amalgam of papers and journal articles? I've always liked going through books (the red book for ID, Park for Cardiology, Polin and Yoder for NICU, etc) rather than uptodate/Peds in review, so if a good one exists I feel like I'd benifit alot from reading it.
