About this study

This is a prospective, single-center, observational clinical trial at the Department of Women's Health of the University Hospital Tübingen.

100 patients affected by uterine diseases with indication for hysterectomy undergo treatment with robotically assisted laparoscopic procedures using the Senhance Surgical System (See Synopsis - Indication A) and are compared to a cohort of 200 patients treated with conventional laparoscopic surgery from a similar ongoing study (Ethics vote: 621 /2018BO1).

100 patients affected by other uterine conditions / adnexal conditions that require uterine/adnexal/tubal surgery (see Synopsis - Indication B) undergo treatment with robotically assisted laparoscopic procedures using the Senhance Surgical System and are compared to a cohort of 200 patients with indication for other uterine conditions / adnexal conditions that require uterine/adnexal/tubal surgery (see Synopsis - Indication B) who underwent conventional laparoscopic surgery at the Department of Women's Health in the past.

At the end of patient recruitment, surgical procedure times, 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.

Patients will answer questionnaires (German version of the Short Form-36health survey questionnaire (Medical Outcomes Trust), German version of the female sexual function index (FSFI)) at baseline and at 3 and 6 months of follow-up. A questionnaire for patient satisfaction will be answered one day post procedural, at discharge and at 3 and 6 months follow-up.

Treatment and study plan

Senhance Surgical System

Procedure

100 patients affected by uterine diseases with indication for hysterectomy undergo treatment with robotically assisted laparoscopic procedures using the Senhance Surgical System

Primary outcomes

  1. operating time

    Time frame: 60 minutes

    time from first incision to skin closure

Secondary outcomes

  1. time under narcosis

    Time frame: 60 minutes

    duration of time in which the study participant is under the influence of a narcotic substance

  2. console time

    Time frame: 60 minutes

    duration of time during which a surgeon is controlling the surgical robot from a console

  3. estimated blood loss (milliliters)

    Time frame: 60 minutes

    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

  4. conversion to other surgical procedures (e. g. open)

    Time frame: 60 minutes

    if the original surgical plan during surgery is altered and switched to a different type of surgery to address unforeseen complications or difficulties that arise during the operation

  5. time to discharge

    Time frame: 60 minutes

    length of time that a patient spends in the hospital before they are well enough to be released and sent home

  6. intraoperative complications

    Time frame: 60 minutes

    (occurring during the surgical procedure)

  7. perioperative complications

    Time frame: 24 hours

    (occurring less than 24h after the surgical procedure)

  8. postoperative complications

    Time frame: 6 months

    (occurring more than 24h after the surgical procedure up to 6 months after surgical procedure)

  9. German version of the Short Form-36health survey questionnaire (Medical Outcomes Trust)

    Time frame: at baseline, and at 3 and 6 months of follow-up

    The SF-36 questionnaire (Short Form 36 Health Survey) is a widely used measure of health status and quality of life. The questionnaire consists of 36 items that measure eight health domains: physical functioning, role limitations due to physical health, bodily pain, general health perceptions, vitality, social functioning, role limitations due to emotional problems, and mental health. The scores range from 0 to 100 for each domain, with higher scores indicating better health status. Therefore, higher scores on the SF-36 indicate a better outcome.

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

    Time frame: at baseline, and at 3 and 6 months of follow-up

    female sexual function index: a multidimensional self-report instrument for the assessment of female sexual function; The total composite sexual function score is a sum of domain scores and ranges from 2.0 (not sexually active and no desire) to 36.0. Higher scores on the FSFI indicate better sexual function.

  11. Questionnaire for patient satisfaction

    Time frame: at one day post procedural, at discharge and at 3 and 6 months follow-up

    Including A Pain Score ( No Pain 0 - Worst Possible Pain 10) and B Satisfaction with: the severity of the pain; the quality of recovery; the scars; the surgery overall (Scale satisfaction: Extremely dissatisfied -- Dissatisfied -- Somewhat dissatisfied -- Neither satisfied nor dissatisfied -- Somewhat satisfied -- Satisfied -- Extremely satisfied)
