Learning Objective #1: The learner will be able to provide a simple, safe, rapid, and less discomfortable modality for bowel preparation for patients under going colonoscopy.
Learning Objective #2: The learner will be able to encourage high risk patients to complaint the order for the early detection of colorectal cancer such as colonoscopy

We compare the effectiveness, acceptability, and patient discomfort of polyethylene glycol (PEG) lavage (Klean-PrepÒ) and magnesium citrate plus cleansing enema prior to colonoscopy. Sixty patients without obstructive colonic disease were randomized to receive either standard 2 L of PEG (n=30) or magnesium citrate plus cleansing enema (n=30), prior to colonoscopic evaluation. The study endpoints were the percentage of subjects who had completed the preparation, the tolerance, discomfort and acceptability assessed by a structured questionnaire. Survey data was analyzed by using SPSS 10.0. There was no significant difference in bowel preparation between PEG group and magnesium citrate/cleansing enema group (p=0.084). However, a significantly lower score of discomfort was found in the PEG group compared to the magnesium citrate/cleansing enema group (3.20±0.37 vs. 1.67±0.58, p=0.000). PEG lavage decreases the discomforts for colonoscopy preparation. Our findings may provide a simple, safe, rapid, and less discomfortable modality for bowel preparation to raise consideration for colonoscopy, and furthermore, to increase the early detection and decrease the mortality of colorectal cancer.
