Ikeda et al reported a nomogram for predicting early endoscopic recurrence after intestinal resection of Crohn's Disease. This can help to identify a patient who may benefit from more aggressive management. The authors are from Osaka University in Japan.
Patient selection: Crohn's disease status post bowel resection
Parameters:
(1) number of previous intestinal resections for Crohn's Disease
(2) preoperative serum albumin in g/dL
(3) excessive perioperative inflammation
points for albumin =
= 180.6 - (45.15 * (serum albumin))

probability of early endoscopic recurrence =
= 1 / (1 + EXP((-1) * X))
