A new low-sodium colonoscopy prep solution did not improve patient acceptance or cleansing quality compared to the standard polyethylene glycol electrolyte solution. Reducing salt concentration is not the key to better patient compliance for colonic cleansing.

Area of Science:

  • Gastroenterology
  • Clinical Nutrition
  • Medical Device Development

Background:

  • Standard polyethylene glycol (PEG) electrolyte solutions for colonic cleansing are associated with an unpleasant salty taste, leading to poor patient acceptance and compliance.
  • A novel low-sodium PEG solution was developed, claiming improved palatability and patient experience.

Purpose of the Study:

  • To evaluate the palatability, tolerance, and cleansing efficacy of a new low-sodium colonic lavage solution compared to the standard PEG electrolyte solution.
  • To determine if reducing sodium concentration enhances patient acceptance and compliance for colonoscopy preparation.

Main Methods:

  • A double-blind, controlled study involving 66 outpatients undergoing colonoscopy.
  • Patients were interviewed regarding palatability and tolerance of the assigned cleansing solution.

  • Preparation quality was objectively assessed via endoscopic examination.
  • Direct taste comparisons between the two solutions were performed.

    • Main Results:

    • No significant differences were observed in palatability, tolerance, or endoscopic cleansing quality between the standard and low-sodium solutions.
    • Patient preference between the two solutions was not statistically significant (51.5% preferred new, 48.5% preferred standard/no preference).
    • A substantial portion of patients could not differentiate the solutions by saltiness, and many preferred the saltier option.

    Conclusions:

    • The new low-sodium lavage solution offers no significant advantage over the standard solution in terms of patient acceptance, compliance, or cleansing effectiveness.
    • Reducing salt concentration in colonic cleansing solutions is unlikely to be an effective strategy for improving patient compliance.
