About this study

Official title: A Study to Evaluate the Yield of Pleural Biopsy With a Flexible Cryoprobe Versus Flexible Forceps During Semirigid Thoracoscopy: a Comparative Study

This is a prospective study to assess the yield of pleural biopsy obtained with the routine flexible thoracoscopic biopsy forceps versus that obtained with a flexible cryoprobe during semirigid thoracoscopy

Read the detailed description

Consecutive patients with exudative pleural effusions who are planned to undergo semirigid thoracoscopy will be enrolled in the study if they satisfy the inclusion criteria. They will be randomized in 1:1 ratio using a computer-generated randomization sequence to the following groups:

Group A: Four pleural biopsy specimens obtained using the flexible cryoprobe followed by eight pleural biopsy specimens obtained using the flexible thoracoscopic forceps OR Group B: The above two procedures will be performed in the reverse order The biopsies will be performed from different areas of the involved pleura with the two techniques. Thoracoscopy will be performed in the bronchoscopy suite on spontaneously breathing subjects (fasting for 8 h) under conscious sedation (using midazolam, pentazocine, and tramadol) observing complete aseptic precautions.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • Cryoprobe pleural biopsy firstDevice

    Four pleural biopsy specimens will be obtained using the flexible cryoprobe (ERBOCRYOCA, ERBE, Tubingen, Germany; outer diameter 1.9 mm, length 900 mm) followed by 6-10 pleural biopsy specimens obtained using the flexible thoracoscopic forceps (FB-55CR, Olympus Medical Systems, 2 mm diameter).

  • Flexible forceps biopsy firstDevice

    Six to ten pleural biopsy specimens will be obtained using the flexible thoracoscopic forceps (FB-55CR, Olympus Medical Systems, 2 mm diameter) followed by four pleural biopsy specimens obtained using the flexible cryoprobe (ERBOCRYOCA, ERBE, Tubingen, Germany; outer diameter 1.9 mm, length 900 mm)

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Yield of pleural biopsy obtained with the routine flexible thoracoscopic biopsy forceps versus that obtained with a flexible cryoprobe during semirigid thoracoscopy

    The proportion of patients where a definitive histopathological diagnosis was obtained will be compared between the cryoprobe and flexible forceps biopsy

    Measured: One week

Secondary outcomes (6)
  1. Biopsy size

    Size of biopsy specimens obtained with the two techniques

    Measured: One day

  2. Duration of procedure

    Time taken for the procedure with the two techniques

    Measured: One day

  3. Ease of biopsy VAS

    Ease of taking biopsy with the two techniques assessed using a visual analog scale

    Measured: One day

  4. Artifacts

    Number of patient speciemens with histopathologic artifacts with either technique including crush artefacts with the flexible forceps and freeze artifacts with the cryoprobe

    Measured: One day

  5. Tissue depth

    Depth of the tissue obtained on histopathology

    Measured: One day

  6. Bleeding

    Number of participants with bleeding seen while taking biopsy categorised into "no bleeding", "minimal self limited ooze", "bleeding requiring prolonged suctioning" , "major hemorrhage requiring blood transfusion, causing hemodynamic instability or ICU admission"

    Measured: One day

Questions about this trial

What is this clinical trial studying?

A study testing Cryoprobe pleural biopsy first and Flexible forceps biopsy first in people with Pleural Effusion and Pleurisy, run by Post Graduate Institute of Medical Education and Research, Chandigarh at 1 site in India.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 2 inclusion and 7 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 31 Aug 2018. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in India. Whether a site is taking part right now should be confirmed with that site. See every site.

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?

Yield of pleural biopsy obtained with the routine flexible thoracoscopic biopsy forceps versus that obtained with a flexible cryoprobe during semirigid thoracoscopy (time frame: One week). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
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 31 Aug 2018.
