Abstract
Introduction: Capsule endoscopy (CE) is the first-line tool for diagnosis of small bowel bleeding. There are some studies that have compared different types of CE. OMOM CE is one of the newest in the market and has not been compared with other types of CE. The objective of this study was to compare the diagnostic yield of the Pillcam SB3 and OMOM CE in small bowel bleeding. Materials and Methods: This is a prospective, comparative, randomized, and blinded study. Patients with suspected small bowel bleeding were included. All the patients were given both types of CE in random order. Diagnostic yield and functionality between the 2 types of CE were analyzed. Results: We included 44 patients, 54.5% were female with a median age of 63.5 years. Battery time was significantly longer with SB3 (816.5 vs. 700.5 min, p < 0.001), and the download time was shorter with OMOM (33 vs. 132 min, p < 0.001). Both CEs presented 1 failure. The cause of the bleeding was identified in 39 SB3 (88.6%) and in 34 OMOM CE (77.3%) (p = 0.256). P2 lesions were observed in 32 SB3 (72.7%) and in 29 OMOM CE (65.9%) (p = 0.784). The agreement between both CEs for P2 lesions was moderate (κ = 0.628). Conclusions: Pillcam SB3 and OMOM devices are safe procedures and have a similar diagnostic yield. Significant differences were observed in the battery life and download time with both CEs.
