No inferioridad entre dos agentes de bajo volumen (picosulfato de sodio/citrato de magnesio frente al sulfato de sodio/potasio/magnesio) en la preparación del colon para procedimientos diagnósticos: estudio observacional / Non-inferiority between two low-volume agents (sodium picosulfate/magnesium citrate vs. sodium sulfate/potassium/magnesium) to prepare the bowel for diagnostic procedures: an observational study

Resumen Introducción: el cáncer colorrectal es un problema de salud pública; sin embargo, la detección temprana reduce su morbimortalidad. La colonoscopia es el procedimiento de elección para detectar lesiones premalignas y el éxito depende de una limpieza adecuada. El objetivo es evaluar el desempeño de dos preparaciones de bajo volumen empleados en un hospital de alto nivel. Materiales y métodos: estudio prospectivo en adultos que asistieran a colonoscopia en la Fundación Santa Fe de Bogotá, Colombia. Las preparaciones se evaluaron con la escala de Boston, con puntaje ≥ 6 puntos para una limpieza adecuada. Se realizó un análisis de regresión logística para establecer la efectividad de los medicamentos con un cálculo de no inferioridad del 3 %-5 %. Resultados: 598 pacientes fueron evaluados. El 49 % (293) fue expuesto al picosulfato de sodio/citrato de magnesio y el 51 % (305) fue expuesto al sulfato de sodio/potasio/magnesio. Con un promedio de Boston de 6,98 ± 1,86 (78 % con puntaje de Boston ≥ 6) y 7,39 ± 1,83 (83 %), respectivamente (p = 0,649). Según el análisis de la presencia y frecuencia de síntomas no deseados, el picosulfato fue mejor tolerado (p < 0,001). Conclusiones: los estudios de preparación intestinal en pacientes de un escenario real son muy escasos. Los medicamentos de bajo volumen obtuvieron una efectividad global y por segmento de colon similar, confirmando la no-inferioridad; el picosulfato de sodio/citrato de magnesio fue mejor tolerado. Un estudio de costo-efectividad podría definir esto según las necesidades de la población de estudio.

Abstract Introduction: Colorectal cancer is a public health problem; however, early detection reduces morbidity and mortality. Colonoscopy is the procedure of choice for detecting precancerous lesions, and success depends on proper bowel cleansing. Objective: To evaluate the performance of two low-volume agents used in a high-level hospital. Materials and methods: Prospective study in adults who underwent colonoscopy at the Fundación Santa Fe in Bogotá, Colombia. Preparations were evaluated using the Boston Bowel Preparation Scale. A score ≥6 points indicated adequate preparation. A logistic regression analysis was carried out to establish the effectiveness of the medicines with a non-inferiority ratio of 3-5%. Results: 598 patients were evaluated. 49% (293) received sodium picosulfate/magnesium citrate and 51% (305) received sodium sulfate/potassium/magnesium, with an average Boston score of 6.98±1.86 (78% Boston ≥6) and 7.39±1.83 (83%), respectively (p=0.649). According to the analysis of the presence and frequency of unwanted symptoms, picosulfate was better tolerated (p < 0.001). Conclusions: Bowel preparation studies in patients from a real-life scenario are scarce. Low-volume agents had similar overall and segmental effectiveness in the colon, confirming non-inferiority; sodium picosulfate/magnesium citrate was better tolerated. A cost-effectiveness study could establish the best option according to the needs of the study population.
