In this population, surgery for Montreal classification B1 disease was more common (22% vs 0%-5%) and performed after shorter disease duration (4.3 vs 6.2-7.1\u2009years) in NL than in other cohorts. Active smoking was more prevalent in NL and FR than in CAN and USA (23%-34% vs 7%-13%). In CAN, 54% were biologic-naive versus 27%-36% in other cohorts. Postoperative prophylaxis was prescribed in 28% of patients in NL and CAN, compared with 48% in FR and USA. Ileocolonoscopy within 12\u2009months was performed in 72% in USA versus 88% in other cohorts. In the re-resection population, B1 disease at surgery and disease duration did not differ, whereas other findings were similar. Endoscopic postoperative recurrence (modified Rutgeerts\u2019 score\u2009\u2265\u2009i2b) varied from 36% in FR to 41% in NL, 15% in USA to 24% in CAN after primary resection and from 43% in NL, 46%
