Preparación para colonoscopia en la vida real.

Introduction: The quality of a colonoscopy is a key factor in clinical outcomes and largely depends on the bowel cleanliness achieved through proper preparation. The type of agent, adherence, and tolerability are factors that can influence the quality of bowel preparation and, consequently, the results of the procedure. This study aims to evaluate the factors that determine the choice of preparation agent and its impact on the quality of colonoscopy. Methodology: A cross-sectional observational study was conducted with a sample of 530 patients. Agents evaluated included polyethylene glycol (PEG), sodium picosulfate, and sodium-potassium-magnesium sulfate (Na-K-Mg sulfate), with their continuous and split-dose regimens, depending on the case. The reasons for selection and tolerability were assessed through a survey. Bowel cleanliness was determined by the endoscopist using the Boston scale. Results: The average age was 52.7 years (±13.4), with 60% being women. The most selected agent was PEG (81.9%) in the full-dose regimen (74.5%). The main determining factor was the availability of the drug, at 42.6%. Unwanted symptoms were reported in 62.6% of patients, however, 99.4% achieved adequate preparation (Boston =6). Conclusion: The primary factor related to the selection of the bowel preparation agent is availability. Objective tolerability does not significantly affect the quality of bowel cleanliness or the success of the procedure. [ABSTRACT FROM AUTHOR]
