Purpose: The usefulness of mechanical bowel preparation (MBP) in colon surgery was recently challenged by many mul-ticenter clinical trials and meta-analyses. The objectives of this study were to investigate current national opinions about MBP and prophylactic antibiotics (PA) and to provide preliminary data for developing future Korean guidelines for MBP and PA administration in colorectal surgery. Methods: A questionnaire was mailed to 129 colorectal specialists. The questionnaires addressed the characteristics of the hospital, the MBP methods, and the uses of oral and intravenous antibiotics. Results: A total of 73 questionnaires (56.6%) were returned. First, in regard to MBP methods, most surgeons (97.3%) used MBP for a mean of 1.36 days. Most surgeons (98.6%) implemented whole bowel irrigation and used polyethylene glycol (83.3%). Oral antibiotic use was indicated in over half (52.1%) of the responses, the average number of preoperative doses was three, and the mean time of administration was 24.2 hours prior to the operation. Finally, the majority of responders stated that they used intravenous antibiotics (95.9%). The responses demonstrated that second-generation cephalosporin-based regimens were most commonly prescribed, and 75 % of the surgeons administered these regimens until three days after the operation. Conclusion: The results indicate that most surgeons used MBP and intravenous antibiotics and that half of them adminis-tered oral PA in colorectal surgery preparations. The study recommends that the current Korean guidelines should b
