“Bottom Line: Clinical Dilemmas in Inflammatory Bowel Disease: New Challengestargets the IBD clinician and is a practical, well-written, easy-to-use text that will be invaluable to all involved in the care of IBD patients, including gastroenterologists, nurses, colorectal surgeons, and dieticians.  Trainee gastroenterologists will find this text useful both in IBD management and as a source for IBD clinical presentations.  I highly recommend this text for anyone who is engaged in the day-to-day clinical care of patients with IBD.”  (Gastroenterology, 1 December 2012)"This is a timely update and expanded second edition that examines many newer clinical dilemmas in IBD. The short chapters are easy to absorb and key opinion leaders offer interesting insights. It certainly justifies replacing the previous edition." (Doody's, 24 February 2012)
