Study summary

This prospective observational registry aims to systematically collect preoperative, intraoperative, and postoperative clinical data from patients undergoing surgery for benign gynecological conditions. The main goal is to evaluate clinical outcomes, surgical approaches, and complications in real-world clinical practice.

Read the detailed description

Benign gynecological diseases frequently require surgical intervention via laparoscopy, laparotomy, vaginal, or robotic approaches. This single-center registry prospectively records baseline patient characteristics, surgical parameters, intraoperative complications, and postoperative outcomes up to 30 days post-surgery (with standard clinical follow-up up to 3 years). The collected data will enable descriptive and exploratory comparative evaluations to optimize perioperative care and surgical management.

Terms in these criteria, in plain language(1)

Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.

Informed consent

Before you join, the study team explains what taking part involves — its purpose, what happens, the risks and possible benefits — and answers your questions, so you can decide freely. Consent is usually recorded on a form (the informed consent form, ICF) signed by you or, where the law allows, by someone legally authorised to decide for you.

You can keep asking questions during the study, you are told of new information that matters, and you can choose to leave at any time.

Groups and cohorts

  • Gynecological Surgery Cohort

    Women with indication for elective benign gynecological surgery undergoing standard clinical surgical procedures (laparoscopy, laparotomy, vaginal, robotic, hysteroscopy, vNOTES).

    Procedure: Standard Surgical Procedures for Benign Gynecological Conditions

Interventions

  • ProcedureStandard Surgical Procedures for Benign Gynecological Conditions

    Patients undergo standard-of-care elective surgery for benign gynecological conditions according to routine clinical practice, including laparoscopy, laparotomy, vaginal surgery, robotic-assisted surgery, operative hysteroscopy, or vNOTES. The choice of procedure is determined solely by clinician judgment and standard medical indication. Data on surgical technique, intraoperative parameters, and perioperative outcomes are recorded prospectively.

What researchers measure

Primary outcomes

  1. Intraoperative and Postoperative Complications

    Incidence and severity of intraoperative and postoperative complications categorized according to the Clavien-Dindo classification

    Time frame: perioperatively/periprocedurally

Secondary outcomes

  1. Operative Time

    Total duration of the surgical procedure measured from skin incision to skin closure, reported in minutes

    Time frame: perioperatively/periprocedurally

  2. Surgical Blood Loss

    Estimated total intraoperative blood loss measured in milliliters (mL)

    Time frame: perioperatively/periprocedurally

  3. Length of Hospital Stay

    Total duration of hospitalization from admission for surgery to hospital discharge, reported in days

    Time frame: up to 30 days

  4. Post-operative Pain Score

    Post-operative pain level assessed using the Numeric Rating Scale (NRS), an 11-point scale ranging from 0 (no pain) to 10 (worst possible pain). Higher scores indicate greater pain severity

    Time frame: perioperatively/periprocedurally

Timeline

Tracking since Sep 25, 2026
ElapsedEstimatedEstimated, not yet reachedSimilar studies: half by the dot; the band is the middle halfHalf of similar studies reached it by the dot; the band is the middle half, from a quarter to three quarters

Start is estimated for Sep 2026; primary completion for Sep 2036, 120 months later.

Of 45 observational studies under Leiomyoma, half reached primary completion within 29 months of starting (the median), counting those still running; a quarter within 16 and three quarters within 99. This study's planned 120 months is above that.

How these figures are worked out, and which studies are left out of them.

What these dates mean
Start.
When the first participant enrolled; while estimated, when the study expects to open to recruitment.
Primary completion.
When the last participant was examined or treated to collect data for the study's main question, its primary outcome. A study that stopped early gives the date its data collection stopped.
Completion.
When the last participant's last visit took place, for every outcome, secondary ones and side effects included: the end of the study. Often later than primary completion, sometimes the same day.
Actual and Est.
Actual means the registry says the date has happened. Est. (estimated) is a date the sponsor plans or expects. It can still move, and the sponsor is expected to change it to actual once it has passed.
No changes since tracking began. The registry record was last updated on Aug 19, 2026, before this site started recording changes on Sep 25, 2026. Its history is on ClinicalTrials.gov ↗
