Objective:
To compare robot assisted laparoscopic platform to standard laparoscopy for the treatment of endometriosis.
Design:
A retrospective cohort controlled study.
Setting:
Tertiary referral center.
Patient(S):
Seventy-eight reproductive aged women.
Intervention(S):
Robot assisted or standard laparoscopy for the treatment of endometriosis between January 2008 and January 2009.
Main Outcome Measure(S):
Operative time, estimated blood loss, hospitalization time, intraoperative and postoperative complications.
Result(S):
Seventy-eight patients underwent treatment of endometriosis, 40 by robot assisted laparoscopy and 38 by standard laparoscopy. The two groups were matched for age, body mass index (BMI), stage of endometriosis, and previous abdominal surgery. Mean operative time with the robot was 191 minutes (range 135-295 minutes) compared with 159 minutes (range 85-320 minutes) during standard laparoscopy. There were no significant differences in blood loss, hospitalization, intraoperative or postoperative complications. There were no conversions to laparotomy.
Conclusion(S):
Both robot assisted laparoscopic and standard laparoscopic treatment of endometriosis have excellent outcomes. The robotic technique required significantly longer surgical and anesthesia time, as well as larger trocars.
