Mechanical Bowel Preparation and Prophylactic Antibiotic Administration in Colorectal Surgery: A Survey of the Current Status in Korea

Abstract

PurposeThe usefulness of mechanical bowel preparation (MBP) in colon surgery was recently challenged by many multicenter 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.MethodsA 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.ResultsA 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.ConclusionThe results indicate that most surgeons used MBP and intravenous antibiotics and that half of them administered oral PA in colorectal surgery preparations. The study recommends that the current Korean guidelines should be adapted to adequately reflect the medical status in Korea, to consider the medical environment of the various hospitals, and to establish more accurate and relevant guidelines.
