Arms Assigned Interventions
Active Comparator: 1
Randomized group of patients receiving conventional laparoscopic hysterectomy
Procedure: Conventional Laparoscopic Hysterectomy
Removal of uterus via standard laparoscopic techniques
Other Names:
  • - Minimal invasive hysterectomy,
  • - Laparoscopic removal of uterus,
  • - Minimal invasive removal of uterus
Active Comparator: 2
Randomized group of patients receiving robot-assisted laparoscopic hysterectomy
Procedure: Robot-assisted (Da Vinci®) laparoscopic hysterectomy
Removal of uterus by robot-assisted laparoscopic technique
Other Names:
  • - Robot-assisted(Da Vinci®)laparoscopic hysterectomy
  • - Robot-assisted minimal invasive hysterectomy

Detailed Description:

During the last few years robot-assisted surgery has been introduced in many surgical specialties and experiences in gynaecological surgery are very limited.

Several aspects like the wider range of motion of robot-instruments leading to more precision in surgery, the 3 dimensional optical system and the ergonomically designed console may offer some advantages. For better judgment these possible benefits as well as safety and outcome need to be evaluated and compared with conventional laparoscopic hysterectomy techniques. This randomized clinical trail intends to compare conventional with robot-assisted(da Vinci®-System) laparoscopic hysterectomy regarding specific parameters. The focus of the study will be to investigate if the robot assisted procedure shows significant advantages for the patient considering duration of surgery, complications, hospitalisation and costs.
