Study summary

Early pregnancy loss happens when a pregnancy that is not developing properly is found on an ultrasound before 12 weeks and 6 days. This type of loss occurs in about 10% of pregnancies. There are three main ways to treat this: waiting for it to pass naturally, using medication, or having surgery. Surgery is the most effective, working 99% of the time, compared to waiting (80% effective in 8 weeks) and medication (71-84% effective). Currently, surgery involves dilation of the cervix and curettage (removal of pregnancy tissue) with suction provided either from a manual hand-held pump or a machine. For the purposes of this study, a manual vacuum aspirator (or hand-held pump) will be used with ultrasound guidance.

There is also another method called hysteroscopic resection, where the doctor uses a special camera to directly see and remove any pregnancy tissue from your uterus. Patients often want the quickest way to resolve the pregnancy loss, and physicians are unsure which surgical method is the best. It's also unclear if one type of surgery causes less scar tissue inside the uterus, affects the ability to test the tissue for genetic issues, or impacts how soon a patient can start fertility treatments again.

This study aims to find out if hysteroscopic resection provides faster resolution and creates less scar tissue compared to the manual vacuum aspiration.

Read the detailed description

Early pregnancy loss is when a nonviable intrauterine pregnancy is diagnosed on ultrasound prior to 12 weeks and 6 days of gestation and occurs in 10% of pregnancies. There are typically three treatment modalities: expectant management, medical management, or surgical management. Surgical management is 99% effective in comparison to expectant management (80% resolution within 8 weeks) and medical management (71-84%). Current standard surgical management includes manual vacuum aspiration or suction dilation and curettage with or without ultrasound guidance. Hysteroscopic resection of retained products of conception (RPOC) has been studied. A recent randomized control trial comparing this to vacuum curettage showed hysteroscopic resection of RPOC had an increase in completeness of removal of the RPOC and decreased need for additional treatment with either a second hysteroscopy or vacuum curettage. Although detailed in 1 case report and performed nationally, hysteroscopic resection in comparison to manual vacuum aspiration of early pregnancy loss has not been investigated. Potential benefits of hysteroscopic resection in comparison to manual vacuum aspiration include faster return to negative bHCG, decreased risk of intrauterine adhesion formation post-operatively, and decreased risk of retained products of conception. Furthermore, 50% of early pregnancy losses are due to fetal chromosomal abnormalities. Thus, diagnosis of a chromosomal abnormality can both provide information for the patient and allow for guidance of pregnancy treatment in the future. A retrospective chart review determined that obtaining fetal genetics is less likely to be contaminated with maternal tissue and is more likely to detect fetal chromosomes when the products of conception were biopsied hysteroscopically prior to suction dilation and curettage rather than when the pregnancy is terminated solely with suction dilation and curettage. Thus, hysteroscopic resection of early pregnancy loss may provide cytogenetic information that may not be obtained with a manual vacuum aspiration (similar technique as suction dilation and curettage, using manual suction instead of electric suction). This study aims to find out if hysteroscopic resection provides faster resolution of the pregnancy loss, creates less scar tissue, and improves genetic testing in comparison to manual vacuum aspiration.

Terms in these criteria, in plain language(2)

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.

Contraindication

A reason a treatment, test or procedure should not be given to a particular person, such as an allergy, another illness or a medicine they take.

Study arms

  • Experimental
    Hysteroscopy

    Participants will undergo hysteroscopic resection of early pregnancy loss under monitored anesthesia care.

    Procedure: Hysteroscopic resection

  • Active comparator
    Manual Vacuum Aspiration

    Participants will undergo manual vacuum aspiration of early pregnancy loss under monitored anesthesia care.

    Procedure: Manual Vacuum Aspiration

Interventions

  • ProcedureHysteroscopic resection

    Participants will undergo a hysteroscopy where a camera is placed on the inside of the uterus. Then a resector will be used to remove the pregnancy loss under direct visualization.

  • ProcedureManual Vacuum Aspiration

    Participants will undergo a manual vacuum aspiration with ultrasound guidance for treatment of early pregnancy loss. This is when pregnancy loss is suctioned by a machine from the uterus.
