Intestinal Preparation in Colonoscopy: Lactulose vs Sodium Phosphate.

Overview

To compare intestinal preparation with Lactulose vs. Sodium Phosphate as the better agent for performing high-quality colonoscopies at the Civil Hospital Fray Antonio Alcalde and the Civil Hospital Juan I. Menchaca, both in Guadalajara, Mexico; as well as Hospital Santo Tomás in Panama City, Panama; and Hospital Gustavo Nelson Collado Ríos in Chitré, Panama; during the period from April 1, 2025, to November 30, 2025. The comparison will focus on colonoscopy quality, patient tolerance, satisfaction, and electrolyte changes, using the agents orally as part of the bowel preparation prior to the colonoscopy procedure.

Randomized Double-Blind Clinical Trial conducted from April 1, 2025, to November 30, 2025, involving patients scheduled for outpatient colonoscopy at the Coloproctology Departments of the Civil Hospital Fray Antonio Alcalde, Civil Hospital Juan I. Menchaca (both in Guadalajara, Mexico), Hospital Santo Tomás in Panama City, Panama, and Hospital Gustavo Nelson Collado Ríos in Chitré, Panama. Patients undergoing elective or emergency therapeutic colonoscopies, as well as those with certain medical conditions or pregnancy, were excluded from the study. Factors related to bowel preparation were considered, with particular emphasis on the characteristics of the chosen preparation agent, its effects, and findings observed during each patient's colonoscopy. All data were collected in a database, which will be shared via a digital platform using the SPSS statistical package for data analysis, followed by the development of conclusions.
