Resumen
Background: capsule endoscopy is increasingly used to obtain images of the gastrointestinal tract, although the best preparation for this type of exploration remains unclear. Aims: the aim of this study was to compare the results of capsule endoscopy explorations performed after a basic preparation with a clear liquid diet, reduced iron intake and fasting or following preparation with a polyethylene glycol (PEG)/ascorbate solution. Methods: the results obtained from a prospective intervention group that used a PEG/ascorbate solution to prepare for capsule endoscopy were compared with those from a retrospective group of patients who followed a more basic preparation. The quality of visualization was assessed with the Park score, the visualization of the mucosal surface and the cleanliness of the intestinal lumen were assessed. The capsule transit time in different segments of the gastrointestinal tract was also evaluated. Results: a significant improvement in the quality of small intestine visualization was observed in individuals prepared with the PEG/ascorbate solution as opposed to the basic preparation. In fact, there were significant differences in the two separate components that contribute to the overall visualization score, with better mucosa visualization and lumen content scores in the intervention group, thus reflecting an improved performance. The presence of diabetes appeared to affect the results of these explorations, at least when using the PEG/ascorbate preparation. Conclusions: preparation with a PEG/ascorbate solution improved the results of capsule endoscopy when compared to a basic preparation, without the inconvenience of the more stringent preparations used for colonoscopies.
