Study summary

This is a prospective, randomized, single-center, observational clinical trial at the Department of Women's Health of the University Clinic Tübingen. Four hundred patients affected by uterine diseases that undergo treatment with robotic assisted laparoscopic procedures using the Da Vinci Robotic Surgical System (200 patients) or conventional laparoscopic surgery (200 patients) will be recruited. In addition retrospective data of 200 patients that underwent conventional laparoscopic surgery in the past will be documented. At the end of patient recruitment, surgical procedure times, the technical limits encountered, estimated blood loss, intra- and post-operative complications and the percentage of conversions from the robotic assisted treatment /conventional laparoscopic surgery to multiple access and/or to a laparotomic (open) approach will be documented.

What researchers measure

Primary outcomes

  1. operative time

    (minutes from first incision to skin closure)

    Time frame: 60 minutes

  2. time under narcosis

    Time frame: 60 minutes

  3. console time

    Time frame: 60 minutes

  4. estimated blood loss (milliliters)

    using the following formula: ((Hemoglobin concentration preoperative (g/l)) - (Hemoglobin 1st day postoperative (g/l)))/((Hemoglobin preoperative (g/l)) - (Hemoglobin 1st day postoperative (g/l)))/2) × 1000

    Time frame: 60 minutes

  5. conversion to other surgical procedures

    Time frame: 60 minutes

  6. time to discharge

    Time frame: 60 minutes

  7. intraoperative complications

    occurring during the surgical procedure

    Time frame: 60 minutes

  8. perioperative complications

    occurring less than 24h after the surgical procedure, according to the Clavien-Dindo classification of surgical complications

    Time frame: 24 hours

  9. postoperative complications

    occurring more than 24h after the surgical procedure up to 6 months after surgical procedure, according to the Clavien-Dindo classification of surgical complications

    Time frame: 6 months

  10. German version of the Short Form-36health survey questionnaire Medical Outcomes Trust

    Medical Outcomes Trust: SF-36 is a set of generic, coherent, and easily administered quality-of-life measures. These measures rely upon patient self-reporting.

    Time frame: 3 and 6 months

  11. German version of the female sexual function index (FSFI) questionnaire

    female sexual function index: a multidimensional self-report instrument for the assessment of female sexual function

    Time frame: 3 and 6 months
