Abstract (EN): Background and study aims Clinical impact of single-balloon enteroscopy (SBE) is fairly known, as well as its diagnostic yield comparing with other small bowel gastrointestinal investigations. This study represents a contribution to better understand it and is designed to evaluate SBE efficacy and degree of concordance with previous evaluation of small bowel. Patients and methods This is a single-center retrospective study of patients that underwent SBE with suspected small bowel disease based on non-invasive imaging. Demographic, clinical, procedural and outcome data were collected for analysis. Agreement beyond positive findings was evaluated using.-coefficient. Results A total of 197 SBEs were performed in 168 patients; mainly men (64.3 %) with mean age 53.3 +/- 17.6 years. Most SBEs (86.3%) performed were preceded by a noninvasive evaluation: in 61.4% (n = 119) of cases, capsule enteroscopy (CE) was performed, in 18.8% (n = 37), computed tomography was performed, and in 6.1% (n = 12) magnetic resonance enterography was performed. Fourty-three patients (25.6%) underwent endoscopic treatments, mainly: argon plasma coagulation in angioectasias (53.4%) and polypectomy (34.9%). The most common diagnoses made with SBE were findings consistent with inflammatory small bowel disease (21.8 %) and vascular lesions (14.2%). The diagnostic yield of SBE was of 69%, confirming the suspicion of small bowel disease. The degree of concordance between CE and SBE for positive findings was substantial, kappa-coefficient = 0.635 (P < 0.001). However, the degree of concordance between imaging examinations (CT or MR) and SBE was only moderate, kappa-coefficient = 0.410 (P < 0.001). SBE had an immediate effect in 20% of patients, changing diagnostic approaches, medical and surgical treatments. Conclusions Our study supports the idea that for suspected small bowel disease, CE and SBE have an overall good degree of concor
