Perioperative Outcomes of Robotic Assisted Laparoscopic Surgery Versus Conventional Laparoscopy Surgery for Advanced-Stage

Background and Objectives: To determine perioperative outcome differences in patients undergoing robotic-assisted laparoscopic surgery (RALS) versus conventional laparo-scopic surgery (CLS) for advanced-stage endometriosis. Methods: This retrospective cohort study at a minimally invasive gynecologic surgery center at 2 academically af-filiated, urban, nonprofit hospitals included all patients treated by either robotic-assisted or conventional laparo-scopic surgery for stage III or IV endometriosis (American Society for Reproductive Medicine criteria) between July 2009 and October 2012 by 1 surgeon experienced in both techniques. The main outcome measures were extent of surgery, estimated blood loss, operating room time, intra-operative and postoperative complications, and length of
