Materials and methods The experimental protocol was approved by the institutional review board (National Cancer Center, #2013-244) and written informed consent was obtained. Participants were 8 healthy Japanese males (age 30-46 years). Exclusion criteria were use of antibiotics in the previous year, previous colonoscopy, smoking, alcohol consumption, and history of appendectomy, diabetes, cardi...

BACKGROUND A complete cleansing of the bowel is a critical factor that impacts the diagnostic accuracy of colonoscopies. However, the common bowel preparation regimen of two 45 mL doses of sodium phosphate (2×NaP) often leads to uncomfortable symptoms and subsequently lower patient adherence. To improve patient adherence and satisfaction, we proposed a modified regimen composed of two sennoside...

BACKGROUND/AIM The aim of this study was to investigate the efficacy of a through- the-scope sodium phosphate solution with completion colonoscopy on the same day as a salvage option for inadequate bowel preparation. MATERIALS AND METHODS All participants were instructed to eat a low residual diet for 3 days before the scheduled colonoscopy and a clear liquid diet 18 h before the colonoscopy....

Our aim was to compare the amount of residual feces, residual fluid, the tagging quality, and patient compliance using 4-day versus 2-day low fiber diet regimen in barium tagging CT colonography in incomplete colonoscopy patients. Methods. A total of 101 patients who underwent CT colonography were assigned to 2-day diet group (n = 56) and 4-day diet group (n = 45). Fecal tagging was achieved wi...

Extensive diagnostic work can be avoided by early toxicological screening of the suspected patients with respect to laxatives. Because no screening method of this kind was available, we developed a procedure with which all phenolic and anthraquinone laxatives--except sodium ...
