Summary

Oral sodium phosphate (NaP) solution provides superior bowel cleansing for colonoscopy compared to senna compound or polyethylene glycol lavage. NaP demonstrated better effectiveness and tolerance, especially for constipated patients.

Area of Science:

  • Gastroenterology
  • Endoscopy
  • Colorectal Cancer Screening

Background:

  • Colonoscopy is the gold standard for detecting and treating colonic lesions.
  • Effective bowel preparation is crucial for colonoscopy success.
  • Comparing different bowel preparation agents is essential for optimizing patient outcomes.

Purpose of the Study:

  • To compare the effectiveness and tolerance of three different bowel preparations for colonoscopy.
  • To evaluate bowel cleansing quality and examination feasibility.
  • To assess the impact of preparation on constipated and non-constipated patients.

Main Methods:

  • A prospective randomized trial involving 300 patients.
  • Patients were assigned to receive senna compound, polyethylene glycol lavage, or oral sodium phosphate (NaP) solution.

  • Endoscopists blindly scored bowel cleansing and examination quality.

    • Main Results:

    • Oral sodium phosphate (NaP) resulted in significantly better bowel cleansing (68%) compared to polyethylene glycol (50%) and senna compound (38%).
    • NaP showed a significant advantage in preparing constipated patients (63%) versus other groups.
    • Examination feasibility was optimal in 80% of cases with NaP, higher than other preparations.

    Conclusions:

    • Oral sodium phosphate (NaP) solutions are highly effective and well-tolerated for bowel preparation before colonoscopy.
    • NaP offers a distinct advantage for constipated patients, with comparable results for others.
    • NaP solution is recommended as the standard preparation for elective colonoscopy.
