Study summary

The investigators conduct a prospective, randomized trial to assess the benefits of performing large loop excision of the transformatione zone (LLETZ) under local anesthesia and compare it to LLETZ under general anesthesia. The primary endpoint of this study is women´s satisfaction.

What researchers measure

Primary outcomes

  1. Womens satisfaction

    Patients will score their satisfaction by using a 11-step visual analogue scale (VAS) ranging from '0' ("not satisfied at all") to '10' ("very satisfied") 2 hours after Treatment

    Time frame: 2 hours

Secondary outcomes

  1. Postoperative pain

    patients will score their postoperative pain Level using a 11-step visual analogue scale (VAS) ranging from '0' ("no pain" ) to '10' ("maximum pain") within 2 hours after surgery

    Time frame: 2 hours

  2. the resected cone mass

    the resected cone mass will be quantified by weighing the removed tissue with a precision scale located in the operating room

    Time frame: 10 minutes

  3. Operation time

    the time from the beginning of the Operation (start of the electrosurgical method) until the end of the operation (the end of hemostatic interventions) will be measured in minutes

    Time frame: 20 minutes

  4. Operative complications

    Operative complications defined as necessity to intervene therapeutically up to 14 days postoperatively

    Time frame: 14 days

  5. Time to complete intraoperative hemostasis

    the time until complete hemostasis as judged by the surgeon has been achieved, will be measured in seconds

    Time frame: 120 seconds

  6. Surgeons satisfaction

    Surgeons will score their satisfaction by using a 11-step visual analogue scale (VAS) 20 minutes after Treatment

    Time frame: 20 minutes

  7. number of fragments of the surgical specimen

    surgeons will count the number of the surgical specimen (1 vs. \>1)

    Time frame: 20 minutes

  8. the dimensions of the surgical specimens

    The circumference, length and thickness of The surgical specimens will be measured

    Time frame: 20 minutes

  9. Intraoperative blood loss

    intraoperative blood loss will be measured using the difference in serum hemoglobin one day prior to surgery and within 5 hours postoperatively

    Time frame: 5 hours

  10. Margin status

    Resection margin is judge as "R0" if abnormal cells are not found in the margin of the biopsy or "R1" if abnormal cells remain in the margin of the biopsy. The histopathological examination will be done by an Independent pathologist

    Time frame: 2 days after conization
