Laparoscopic colorectal resections with and without routine mechanical bowel preparation- A comparative study

Background

The benefit of mechanical bowel preparation (MBP) in patients undergoing laparoscopic colorectal resections remains a question. This study aimed to evaluate the effect of omitting MBP on patients undergoing laparoscopic bowel resections.

Methods

The outcomes of patients who underwent elective colorectal resections for cancer of colon and upper rectum without MBP were compared to a retrospective cohort who had MBP.

Results

There were 97 patients in the No-MBP group and 159 patients in the MBP group. Their mean age, operative risk, tumor size and stage of disease were similar. There were no significant differences in operative time and estimated blood loss. The anastomotic leakage rate was 1.0% in the No-MBP group and 0.6% in the MBP group, (p = 1.00). Wound infection rate were 4.1% and 3.8% in the No-MBP group and the MBP group respectively (p = 1.00). Overall surgical morbidity rate was 11.3% in the No-MBP group and 8.2% in the MBP group (p = 0.40). Conversion rates were 5.2% in the No-MBP group and 6.9% in the MBP group, (p = 0.57).

Conclusion

The omission of mechanical bowel preparation does not increase surgical morbidities in patients undergoing laparoscopic bowel resections. It also has no effect on operating time and conversion rate.
