Study summary

This randomized controlled trial was conducted in the Department of Obstetrics and Gynecology, Sheikh Zayed Hospital, Rahim Yar Khan, to compare two commonly used methods for obtaining endometrial tissue in women aged 30 to 60 years presenting with abnormal uterine bleeding. Endometrial sampling is required to identify the underlying cause of abnormal bleeding, including precancerous changes and endometrial cancer. Participants who met eligibility criteria and provided informed consent were allocated to undergo either manual vacuum aspiration or dilatation and curettage. The primary purpose was to determine whether there was a significant difference between the two procedures in obtaining an adequate endometrial sample for histopathological reporting, where adequacy was defined as tissue containing both endometrial glands and stroma in sufficient quantity for interpretation. Pain severity was additionally assessed 24 hours after the procedure using a visual analog scale. The study hypothesis was that a significant difference existed in endometrial sampling adequacy between manual vacuum aspiration and dilatation and curettage among women with abnormal uterine bleeding.

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

  • Females aged 30-60 years.
  • Patients presenting with abnormal uterine bleeding (AUB) as per operational definition.
  • Patients who provide to participate in the study.

Exclusion criteria

Exclusion Criteria:

  • Patients with known pregnancy, active pelvic infection, or untreated sexually transmitted infections as per medical records.
  • Patients with known coagulopathy, bleeding disorders, or currently on anticoagulant therapy.
  • Patients with a history of endometrial or cervical cancer, abnormal Pap smear, pelvic pathology, or current hormonal use for endometrial pathology.
  • Patients who have undergone surgical intervention involving the uterus in the past three months.
  • Patients with severe medical conditions that could interfere with the study outcomes or pose a risk during the procedure (e.g., severe cardiovascular disease, uncontrolled diabetes).
  • Patients with a history of severe allergic reactions to local anesthesia or NSAIDs were used in the study.
  • Patients with stenotic cervical ostium.
  • Females with undergoing chemotherapy or radiotherapy (as per medical records).
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.

Cancer (malignancy)

Malignancy means cancer. Criteria about another or earlier malignancy ask whether you have had a different cancer, usually within a set number of years.

Some are commonly allowed, such as treated skin cancers other than melanoma and early cancers removed completely — check the exceptions this study lists.

Study arms

  • Experimental
    Group Manual Vacuum Aspiration

    Performed under paracervical block using 1% xylocaine with adrenaline in an outpatient setting.

    Procedure: Manual Vacuum Aspiration

  • Active comparator
    Group Dilatation and Curettage

    Performed under paracervical block using 1% xylocaine with adrenaline.

    Procedure: Dilatation and Curettage

Interventions

  • ProcedureManual Vacuum Aspiration

    Endometrial tissue was obtained using a handheld manual vacuum aspirator with appropriately sized cannula (No. 3 to No. 12), generating negative pressure to aspirate tissue from the endometrial cavity for histopathological examination.

  • ProcedureDilatation and Curettage

    The cervix was gradually dilated using cervical dilators, followed by curettage of the endometrial lining with a curette to obtain tissue for histopathological examination.

What researchers measure

Primary outcomes

  1. Adequacy of endometrial tissue sample

    Adequacy of the endometrial specimen was determined by a consultant histopathologist and defined as the presence of both endometrial glands and stroma in at least 50% of the specimen, with minimal contamination by blood, mucus, or necrotic tissue, and preservation of tissue integrity sufficient for accurate histopathological interpretation.

    Time frame: During the procedure and at the time of histopathological examination of the collected specimen

Secondary outcomes

  1. Post-procedure pain score

    Pain intensity was assessed using the Visual Analog Scale, a 10-centimeter scale ranging from 0 representing no pain to 10 representing the worst pain imaginable. Each participant marked the perceived pain level, and the recorded value was used for analysis.

    Time frame: 24 hours after the endometrial sampling procedure

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

Started Sep 2025 (actual). Primary completion is estimated for Feb 2026, 5 months after the start.

Of 41 non-industry interventional studies with no phase under Metrorrhagia, half reached primary completion within 17 months of starting (the median), counting those still running; a quarter within 6 and three quarters within 30. This study's planned 5 months is below that.

Counting every sponsor, half of 43 studies reached it within 17 months; a quarter within 6 and three quarters within 30.

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 Jan 16, 2026, before this site started recording changes on Sep 25, 2026. Its history is on ClinicalTrials.gov ↗
