AIM: During the last decade, treatment protocols have changed for patients with ileocolic Crohn's disease. Anti-tumour necrosis factor (anti-TNF) has become part of standard medical treatment, usually in a step-up approach. The aim was to analyse if improved medical treatment has resulted in more limited ileocolic resections and a longer interval between diagnosis and surgery. METHOD: Patients undergoing ileocolic resection for Crohn's disease were included (1999-2014). Patient characteristics were compared to the results of a population-based study (between 2004 and 2010) previously performed in the catchment area of the present tertiary referral centre. Time trends were analysed using the Cochrane-Armitage trend, Spearman's correlation coefficient and linear regression. RESULTS: In total, 195 patients undergoing ileocolic resection were included. Patient characteristics were not significantly different from the background cohort, confirming a representative study group. Sixty-three patients were men (32.3%, median age at surgery 30.0 years, interquartile range 23.0-40.0). Anti-TNF and immunomodulator use prior to surgery increased significantly during the study period (χ2 = 49.1, P < 0.001). Over the years, a significant increase in time from diagnosis to operation was found (median 39.0 months, interquartile range 12.0-86.0, rho 0.175, P = 0.014). The length of the resected ileum did not change significantly (median 20.0 cm, interquartile range 12.0-30.0, rho -0.107, P = 0.143). The number of fistulas or postoperative complications that needed re-intervention was not significantly different between the groups with or without anti-TNF. CONCLUSION: This study demonstrated that over time patients with ileocolic Crohn's disease who eventually underwent ileocolic resection have been treated more intensively medically; however, this did not result in reduced specimen size.
