Abstract
In Japan several reports, PEG method was rapid, effective and well-tolerable compared with the conventional method, but more than 3, 000 ml of PEG was necessary in preparation for colonoscopy. More than 3, 000 ml of PEG is a problem of unacceptance of patient. Therefore, we developed Combination method (sennoside and metoclopramide) in order to decrease the ingested volume of PEG and improve patient acceptance. To determine the usefullness of Combination method, 20 Patients were received Combination method and PEG method for colonoscopy at interval of one week. The both methods were equally adequate due to colon cleansing, but Combination method had significantly less water retension than PEG method. The ingested volume of Combination method (2, 000 ml) was significantly less than that of PEG method (2, 610 ml), and the time required for ingestion of Combination method (120 minutes) was significantly shorter than that of PEG method (167 minutes). Combination method was superior to PEG method due to patient acceptance. This study suggests that Combination method is effective and well tolerated by patients, and has become the standard method using PEG in preparation for colonoscopy.
