BACKGROUND: To prevent surgical site infection (SSI) in colorectal surgery, the combination of mechanical bowel preparation (MBP), oral antibiotic bowel preparation (OABP), and the intravenous antibiotics have been proposed as standard treatment. We conducted an RCT comparing the incidence of SSI between MBP + OABP and OABP alone after receiving a single dose of intravenous antibiotics. METHODS: The study group comprised 254 patients who underwent elective surgery for colon cancer. Patients were randomly assigned to receive MBP + OABP and intravenous antibiotics (MBP + OABP group) or to receive OABP and intravenous antibiotics (OABP alone group). RESULTS: Overall, 125 patients in MBP + OABP group and 126 patients in OABP alone group were eligible. Incisional SSI occurred in 3 patients (2.4%) in MBP + OABP group, and 8 patients (6.3%) in the OABP-alone group. Organ/space SSI developed in 0 patients (0%) and in 4 patients (3.2%) in each group respectively. The OABP-alone group was thus not shown to be noninferior to the MBP + OABP group in the incidences of incisional SSI or organ/space SSI. Other infectious complications developed in 7 patients (5.6%) and in 6 patients (4.8%) in each group, indicating the non-inferiority of OABP alone to MBP + OABP. CONCLUSIONS:MBP combined with oral antibiotics and intravenous antibiotics remains standard in elective colon cancer surgery.
