Abstract Background In small bowel capsule endoscopy (SBCE), the presence of residue may compromise diagnostic accuracy. Aims To assess differences in quality of visualisation and diagnostic yield of SBCE using 3 different preparation protocols. Methods Prospective, randomized, blind, pilot study. Protocol A:Clear liquids diet the day before the examination with fasting from 8p.m.; Protocol B:Protocol A + 2 pouches of Moviprep ® (polyethylene glycol electrolyte solution + sodium ascorbate) in 1 L of water from 8p.m. of the day before the examination; Protocol C: Protocol A + 2 pouches of Moviprep ® in 1 L of water consumed after real-time confirmation of capsule arrival at small bowel. Small bowel preparation was classified by two experienced physicians, considering the percentage of the examination during which mucosal observation was adequate: Excellent(>90%); Good(90–75%); Fair(75–50%); Poor(<50%). Results 101 patients randomized to the 3 protocols (A 37, B 31, C 33 patients). Protocol C had an excellent/good small bowel preparation in a higher percentage of examinations for both readers(Reader 1-A:37.8% vs B:45.2% vs C:78.8%, p = 0.002 and Reader 2 –A:37.8% vs B:41.9% vs C:75.8%, p = 0.003). Also, protocol C had a higher detection of angioectasia (A:5.4% vs B:9.7% vs C:27.3%, p = 0.022). Conclusions The administration of Moviprep ® after the capsule had reached the small bowel was associated with a better small bowel preparation and a higher detection of angioectasia.
