The Effect of Mechanical Bowel Preparation on the Surgical Field in Laparoscopic Gynecologic Surgeries: A Prospective...

To evaluate the effects of mechanical bowel preparation (MBP) on the intraoperative visualization of the surgical field, bowel handling, intestinal load, and overall ease of surgery in patients undergoing elective laparoscopic gynecological surgeries.

The patients randomized to a MBP group and a no preparation (NMBP) group. The senior surgeon remained blinded to the bowel regimen used by the patient. Intraoperative visualization of the surgical field, bowel handling, intestinal load, and overall ease of surgery were evaluated using a numeric rating scale (NRS).

We enrolled 120 patients, of whom 109 completed the study, with 51 and 58 patients in the MBP and NMBP groups, respectively. The intraoperative visualization of the surgical field, intestinal load, and NRS scores for overall ease of surgery were better in the NMBP group (p = .03, p = .048, and p = .022, respectively). The results of the assessments also revealed no significant differences in surgical field visualization, ease of bowel handling, overall ease of surgery, or the time that patients experienced passage of flatus between obese (BMI > 30 kg/m²) and non-obese (BMI ≤ 30 kg/m²) patients in the two groups.

The current study revealed that MBP did not improve the intraoperative visualization of the surgical field or the overall ease of surgery. Moreover, MBP had no benefit when operating on patients who had a high BMI. Therefore, we do not recommend routine MBP before laparoscopic gynecological surgeries.
