Background and Aim: Minimal data are available regarding the performance of video capsule endoscopy (VCE) in patients who underwent bariatric surgery. We aimed to report indications, feasibility, and safety of VCE performed after bariatric surgery, specifically focusing on diagnosis rates of Crohn's disease (CD) in this population. Methods: A retrospective analysis of all VCE procedures was performed between January 2015 and December 2019. All patients who underwent bariatric surgery prior to VCE were included. Indication for VCE, ingestion methods, completion rates, retention rates, and endoscopic findings were recorded. Results: A total of 1,255 patients underwent VCE examination during the study period, of which 31 (2.5%) underwent bariatric surgery prior to VCE. The most common bariatric surgery was laparoscopic sleeve gastrectomy (16 patients, 51.6%), and the most common indication for VCE was evaluation of iron deficiency anemia (14 patients, 45.1%). The majority of patients ingested the capsule independently, without endoscopic assistance (20, 64.5%). Although a patency capsule was not used in our cohort, no events of capsule retention were documented. Mean transit time was 4.32 h. Only 4 events of incomplete examination were recorded. Over a median follow-up of 27.5 months (IQR 13.0-34.2), 10 patients (31.2%) had a final diagnosis of CD with a median Lewis score of 225 (IQR 135-900). Conclusion: VCE is a feasible and safe procedure after bariatric surgery. Oral ingestion does not carry risk of retention. It is an effective means of diagnosis of small-bowel CD in this population.
