- InterventionsPatients were randomized before elective colorectal surgery to receive mechanical bowel preparation, consisted of 2-4 liters of polyethylene glycol bowel lavage solution in combination with a fliud diet in one study arm. The other study arm received no mechanical bowel preparation and was allowed to have a normal meal on the day before operation.
- Primary outcomeThe primary endpoint of the study was anastomotic failure, which was based on clinical suspicion (prolonged fever, abdominal pain, local or generalized peritonitis, leucocytosis) resulting in contrast radiography (X-ray or CT-scan) or laparotomy to confirm the diagnosis. No effort was made to screen for asymptomatic leakage.
- Secondary outcomeSecondary endpoints were septic complications (wound infection, urinary tract infection, pneumonia, pelvic abscesses), fascia dehiscence and death.

Mechanical bowel preparation. Colorectaal themajaar 2005, closing congress, Nederlandse Vereniging voor Gastrointestinale chirurgie, Noordwijk, november 2005
- Brief summaryMechanical bowel preparation (MBP) is common practice in elective colorectal surgery. In recent literature the value of MBP is subject of discussion. We conducted a multicenter, randomized study with the goal of comparing outcome of elective colorectal resections and primary anastomoses with and without mechanical bowel preparation in terms of anastomotic leakage and other septic complications. Within the setting of a multicenter randomized trial,1433 patients were randomized before elective colorectal surgery to receive either MBP or to have no MBP but a normal meal on the day before operation. The primary endpoint was anastomotic leakage. Secondary endpoints were septic complications (wound infection, urinary infection, pneumonia, pelvic abscesses), fascia dehiscence and death. The incidence of anastomotic leakage was similar in both groups: 5.1% in patients without MBP versus 4.9% in patients with MBP (p=0.93; 95% confidence interval for the difference (no MBP minus MBP) ranges from 2.3% tot +2.7%). There were no significant differences in other septic complications, fascia dehiscence, or mortality. Fecal contamination, number of days until resumption of a normal diet, and duration of hospital stay were similar in both groups.
This study shows that elective colorectal surgery can be safely done without MBP. Therefore, MBP should be abandoned in elective colorectal surgery.
