title: A randomized trial comparing conventional and robotically assisted total laparoscopic hysterectomy.
abstract: OBJECTIVE
  The purpose of this study was to compare operative time and intra- and postoperative complications between total laparoscopic hysterectomy and robotic-assisted total laparoscopic hysterectomy.
  
  
  METHODS
  This study was a blinded, prospective randomized controlled trial conducted at 2 institutions. Subjects consisted of women who planned laparoscopic hysterectomy for benign indications. Preoperative randomization to total laparoscopic hysterectomy or robotic-assisted total laparoscopic hysterectomy was stratified by surgeon and uterine size (> or ≤12 weeks). Validated questionnaires, activity assessment scales, and visual analogue scales were administered at baseline and during follow-up evaluation.
  
  
  RESULTS
  Sixty-two women gave consent and were enrolled and randomly assigned; 53 women underwent surgery (laparoscopic, 27 women; robot-assisted, 26 women). There were no demographic differences between groups. Compared with laparoscopic hysterectomy, total case time (skin incision to skin closure) was significantly longer in the robot-assisted group (mean difference, +77 minutes; 95% confidence interval, 33-121; P < .001] as was total operating room time (entry into operating room to exit; mean difference, +72 minutes; 95% confidence interval, 14-130; P = .016). Mean docking time was 6 ± 4 minutes. There were no significant differences between groups in estimated blood loss, pre- and postoperative hematocrit change, and length of stay. There were very few complications, with no difference in individual complication types or total complications between groups. Postoperative pain and return to daily activities were no different between groups.
  
  
  CONCLUSIONS
  Although laparoscopic and robotic-assisted hysterectomies are safe approaches to hysterectomy, robotic-assisted hysterectomy requires a significantly longer operative time.
