title: Colectomy without mechanical bowel preparation in the private practice setting.
abstract: BACKGROUND
  Despite randomized trials and meta-analyses demonstrating the safety of omitting mechanical bowel preparation (MBP) before colorectal surgery, private practice surgeons may hesitate to eliminate MBP for fear of being outside community standards. This study evaluated the safety of eliminating MBP before colectomy in a private practice setting.
  
  
  METHODS
  This prospective observational study included elective abdominal colorectal operations from one surgeon's practice from October 2008 to June 2011. MBP was not routinely utilized after November 2009. Postoperative 30-day complication rates and length of hospital stay were compared in patients with and without MBP. Multivariable regression models were developed to compare outcomes among study groups, adjusting for demographics, diagnoses, procedures, and year.
  
  
  RESULTS
  A total of 165 patients were analyzed. Demographics were similar between groups. Laparoscopic procedures were more common in patients without MBP due to increased laparoscopy over time (43 vs. 61 %, p = 0.03). As regards complications, infection rates were similar between groups (MBP 10.5 % vs. no MBP(NMBP) 11.4 %, adj p = 0.57). Patients without MBP had a shorter length of hospital stay (median: 6 vs. 5 days, p = 0.01), but those differences were not statistically significant after adjustment (p = 0.14).
  
  
  CONCLUSIONS
  Private practice surgeons should embrace evidence-based practice changes and make efforts to quantitatively evaluate the safety of those changes. Omission of MBP for most elective colectomy procedures appears to be safe with no significant increase in complications or length of hospital stay. Because MBP has substantial drawbacks, there is little justification for its routine use in the majority of elective abdominal colorectal procedures.
