Go through the criteria one by one — yes, no or not sure — and take the list to your doctor or the study team. Kept in this browser only.

Inclusion criteria

  • Symptomatic (dysmenorrhea, palpable mass, pelvic pain or discomfort urinary symptom, increasing size, menorrhagia) myomas or adenomyomas
  • Uterine size \< gestational age of 14 weeks

Exclusion criteria

Exclusion Criteria:

  • Medical diseases such as heart failure, renal insufficiency, liver cirrhosis, pancreatitis, uncontrolled DM
  • Huge uterine size > gestational age of 14 weeks
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.

What researchers measure

Primary outcomes

  1. Conversion rate

    Conversion means that events required additional port(s) or open laparotomy

    Time frame: 1 week

Secondary outcomes

  1. Patient and Observer Scar Assessment Scale (POSAS)

    Time frame: 12 weeks

  2. Postoperative pain

    Measured by numeric rating score (NRS)

    Time frame: postop. 1 day, 1 week

The record gives a start of Dec 2011, a primary completion of Dec 2012 and a completion of Mar 2013. It does not say whether these dates are actual or estimated.

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 Feb 22, 2012, before this site started recording changes on Sep 25, 2026. Its history is on ClinicalTrials.gov ↗
