Background & Aims: The Rutgeerts' scoring system is used to evaluate patients with Crohn's disease (CD) following ileocolic resection, based on endoscopic findings at the anastomosis and in the neoterminal ileum. We investigated rates of clinical and surgical recurrence of CD after surgery and effect of therapy modification based on post-operative endoscopic findings.
Methods: We collected data from 365 adults with CD (20% with Rutgeerts' score i0, 10% with score i1, 49% with score i2, 12% with score i3, 9% with score i4) who underwent ileocolonoscopy within 12 months of ileocolic resection with anastomosis from 2000 through 2013 at 2 centers in Belgium and France.
Background: The Crohn's Disease Activity Index (CDAI) has been criticized for being weakly correlated with bowel inflammation. We assessed correlation between Simple Endoscopic Score for Crohn's Disease (SES-CD) and individual CDAI items stratified by disease location to better understand this relationship.
Methods: We pooled patient-level data from 3 placebo-controlled Crohn's disease (CD) trials that tested adalimumab, upadacitinib, and risankizumab.
Endoscopic evaluation for postoperative recurrence of Crohn's disease (CD) is routinely integrated into clinical practice. The Rutgeerts score (RS) was developed to grade the severity of endoscopic postoperative CD recurrence and has been integrated into clinical practice guidelines and utilized as an endpoint in interventional trials. However, the operating properties of the RS have not been fully assessed.

Methods: We evaluated the effects of ustekinumab on histologic CD activity in an analysis of data from 251 participants in phase 3 induction and maintenance studies. Two endoscopic biopsy samples were collected at weeks 0, 8, and 44 from the ileum, splenic flexure, and rectum (18 biopsy samples from each patient).
Background And Aims: Following induction/maintenance treatment in the UNITI/IM-UNITI studies of ustekinumab for Crohn's disease, patients entered a long-term extension for up to 5 years from induction. Efficacy through 152 and safety through 156 weeks are reported.
Methods: At IM-UNITI Week 44, 567 ustekinumab-treated patients entered the long-term extension and continued to receive blinded subcutaneous ustekinumab on their assigned dose interval, without any subsequent dose adjustment.
