Patients often dislike the taste of polyethylene glycol-electrolyte lavage solutions for colonoscopy preparation. Adding lemon flavoring significantly improved patient preference for these gastrointestinal lavage solutions.

Area of Science:

  • Gastroenterology
  • Clinical Nutrition
  • Medical Device Technology

Background:

  • Oral gastrointestinal lavage solutions, particularly polyethylene glycol-electrolyte solutions, are essential for colonoscopy preparation.
  • Patient non-compliance with colonoscopy preparation is often linked to the unpalatable taste and large volume of these solutions.
  • Improving the palatability of these solutions may enhance patient tolerance and adherence to bowel preparation protocols.

Purpose of the Study:

  • To evaluate the impact of flavoring on patient preference and tolerance of polyethylene glycol-electrolyte lavage solutions.
  • To determine if lemon flavoring can mitigate the disliked salty taste of standard colonoscopy preparation solutions.
  • To assess patient preference between standard and flavored lavage solutions in a randomized, controlled setting.

Main Methods:

  • A randomized study involving 56 patients undergoing colonoscopy.
  • Comparison of standard polyethylene glycol-electrolyte lavage solution with lemon-flavored or lemon/lime-flavored solutions.
  • Patient preference was recorded for different solution combinations across three study groups.

Main Results:

  • In Group I, 93% of patients preferred lemon-flavored Colyte over standard Colyte.
  • In Group II, 80% of patients preferred standard Colyte over lemon/lime-flavored Colyte.
  • In Group III, 90% preferred lemon-flavored Colyte, while none preferred NuLYTELY, indicating a strong preference for lemon flavoring.

Conclusions:

  • Lemon flavoring significantly enhances patient preference for polyethylene glycol-electrolyte lavage solutions.
  • Flavoring appears to be a viable strategy to improve patient compliance and tolerance for colonoscopy preparation.
  • Further research may explore optimal flavoring agents and concentrations for gastrointestinal lavage solutions.
