About this study
In this study, a comparison is made between two types of polyp resection methods (hand driven and motor driven morcellation). More specifically, the effects of the resection on symptoms such as abnormal uterine bleeding, and on the recurrence of polyps.
The aim of the study is to find a superior method in terms of symptom relieve and polyp recurrence so this method can be used in gynaecological practice.
Read the detailed description
- Rationale: several techniques for hysteroscopic removal of intrauterine polyps exist today. Hysteroscopic morcellation is an effective, fast, and safe method for this. However, the differences between two different systems of hysteroscopic morcellation, motor-driven (Truclear incisor mini device) and hand-driven (Resectr 9fr) morcellation, are still unclear. The REMOvE9 study, in which women with a polyp were randomized between both techniques, is currently investigating the differences in short-term effectiveness between the two techniques.
- Research question/goal: To investigate the long-term results of the effectiveness of a hysteroscopic morcellation of intrauterine polyps. The two systems are compared with each other.
- Study design: This is a prospective cohort study. The patients previously participated in a randomized controlled trial (REMOvE9) and will now be contacted again for the completion of a one-time questionnaire. The study has an observational design.
- Study population: Women with a history of endometrial polyp that was previously removed via hysteroscopic morcellation in the REMOvE9 study.
- Primary and secondary endpoints: The primary endpoint is the risk of recurrence of abnormal uterine bleeding at post-surgery follow-up. Secondary endpoints include recurrence of other symptoms, time to recurrence, symptom relief, onset of new symptoms, onset of new polyp, satisfaction with regards to symptoms, satisfaction with regards to the treatment in general, need for additional treatments for blood loss and occurrence of pregnancy (in subfertility group).

What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
Are results available for this study?
The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.
How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Rate of recurrence of abnormal uterine blood loss (+ cause, treatment) (time frame: 1 to 4 years). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
On the ClinicalTrials.gov record for NCT05337605, which also lists 1 linked publication.
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 13 Jul 2023.
