Purpose: This study was undertaken to determine whether a mechanical bowel preparation with 2 liters polyethylene glycol solution combined with a Bisacodyl 20 mg (Group II) increases the acceptability of bowel preparation and reduces discomfort<br>compared<br>with 4 liters of polyethylene glycol solution (Group I).<br>Methods: We conducted a prospective randomized single-blinded study. Eighty patients undergoing an elective colorectal surgery in Severance hospital from April 1999 to September 1999 were included in this study. The patients' tolerance, cleansing<br>ability and surgeon's satisfaction were assessed by a structured questionnaire. Postoperative complications were also evaluated. Results: The patients' tolerance of the group II (2 liters polyethylene glycol solution combined with a Bisacodyl 20<br>mg) was<br>better than that of the groups I (4 liters of polyethylene glycol solution). The cleaning ability and surgeon's satisfaction were not different between two groups (p=0.225, p=0.322). The incidence of postoperative complications was 2.3 percent in<br>Group<br>I and 2.7 percent in Group II. Conclusions: The mechanical bowel preparation with two liters of polyethylene glycol solution with a Bisacodyl 20 mg was more comfortable to patients and equally efficient compared with the mechanical bowel<br>preparation<br>with the 4 liters of polyethylene glycol solution regimen before elective colorectal surgery.<br>
