Abstract Background Small bowel capsule endoscopy (SBCE) is widely used for various indications in patients with established Crohn’s disease (CD). Our aim was to investigate whether SBCE can lead to changes in the therapeutic management of CD patients. Methods Retrospective analysis of prospectively collected data [September 2003 - September 2019] from patients with established CD subjected to SBCE in two tertiary referral centres for inflammatory bowel diseases. All patients were tested with the Pillcam SB. Findings consistent with small bowel CD involvement were the presence of aphthoid or larger ulcers with or without inflammation of the adjacent mucosa. Results In total, 839 patients [median age (range) 36 (17–78) years, 471 (56.41%) men, median disease duration 6 years] diagnosed with CD according to established criteria underwent SBCE in the participating centres for the evaluation of disease extent and mucosal healing or the investigation of clinical relapse or iron deficiency anaemia. Based on ileo-colonoscopy findings disease location was documented in 618 patients (73.65%) as follows: colitis in 219 (26.10%), ileo-colitis in 253 (30.15%), and terminal ileitis in 146 (17.40%) patients; in contrast, full disease location was not documented in 221/839 (26.34%) patients who had colonic involvement but the ileocaecal valve could not be intubated. In the latter group, SBCE revealed small bowel involvement in 96 (43.43%) patients. In addition, SBCE revealed more proximal lesions in 105/618 (16.99%) patients with ileo-colonoscopy documented colitis, ileo-colitis or terminal ileitis. These findings led to a change in therapeutic management in 98 patients (11.68%): 36 patients (4.29%) received biologics, 21 patients (2.50%) received intensified doses of or changed the administered biologic, 39 patients (4.64%) received corticosteroids and/or conventional immunosuppressants and 2 patients (0.23%) underwent surgery. Therapeutic management changes were commoner in patients in whom small bowel lesions were found during SBCE and in whom the terminal ileum had not been examined during colonoscopy (57/96 patients vs. 41/105, p = 0.003]. Capsule retention occurred in 9 patients (1.07%) and passed after administration of corticosteroids (n = 6), or the capsule was retrieved with push enteroscopy (n = 1) or surgery (n = 1). Conclusion SBCE is a valuable tool in the management of patients with established CD, especially in those whom the terminal ileum has not been e
