HealthDay News — Pulsed irrigation evacuation (PIE) and sodium phosphate are superior to polyethylene glycol (PEG) for colon preparations prior to colonoscopy, according to a study published online November 21 in the Journal of Digestive Diseases.

Kamran Ayub, MD, from Silver Cross Hospital in New Lenox, Ill., and colleagues compared screening colonoscopy colon prep methods: PIE (135 patients), PEG (129 patients), and sodium phosphate (127 patients) among 391 outpatients at a Veterans Affairs hospital (mean age, 62 years; 75% men).

The researchers found that PIE and sodium phosphate were superior to PEG, with both receiving a score of 4 on a 5-point scale (blind assessment), versus a 3 for PEG (P<0.01). PEG was associated with more inadequate preps, compared to PIE (18 vs. 5%; P<0.01). Vomiting was reported in 37% of patients with sodium phosphate, 5 percent with PEG, and 2% with PIE (P<0.01).

PIE Medical International donated the PIE machine and supplies for this study.
