In this prospective randomised single-blind case-controlled cohort study the aim was to compare the effects of mechanical bowel preparation (MBP) on field of vision and surgical comfort during total laparoscopic hysterectomy procedures. The study group was made of 102 patients that had undergone total laparoscopic hysterectomy (TLH), between July 2012 and June 2014. Statistical comparison was made between the means of durations of operation between the two groups divided by visual indexing (VI). The patients with a VI score of less than 2 and those with VI score of 2 or higher were compared in terms of operation duration in regard to the criteria described above. According to calculations, the p value is.664, therefore, making the result statistically not significant at p ≤.05. In conclusion it can safely be reported that mechanical bowel preparation before laparoscopic hysterectomy was not found to be necessary in this study group.
