Endoscopic assessment within 6 to 12 months of ileocolonic resection has been the mainstay of management of postoperative Crohn's disease. The original Rutgeerts score to grade endoscopic recurrence was designed for predicting prognosis after resection. However, it is increasingly recognized that the clinical course of disease varied based on anatomic location of lesion rather than only severity of endoscopic lesions. It is also important to recognize several anatomic landmarks around surgical anastomosis, given the vast technical modifications in surgical technique over the past few decades. It is important to understand the changing paradigm of assessing endoscopic recurrence as it considerably influences subsequent therapeutic management.
