About this study

Official title: BiClamp Forceps Liver Transection Versus Clamp Crushing Technique in Liver Resections: A Randomized Clinical Trial

The purpose of this study is to compare short-term and long-term efficacy of BiClamp forceps hepatectomy and clamp-crushing technique for parenchymal transection during elective hepatic resection.

Read the detailed description

Background: Blood loss and the need for blood transfusions during the liver transection have shown to be correlated with higher morbidity and mortality rates and with worsen prognosis. Various devices of liver parenchymal transection have been developed with a view to reducing the intraoperative blood loss. However, to the present there is no randomized controlled trial evaluating the technique of BiClamp forceps during the liver transection. The goal of the present study was to evaluate the safety and effectiveness of BiClamp forceps transection in comparison to the clamp crushing technique in patients offered liver resection.

Intervention: One hundred patients with hepatobiliary disease need undergo hepatectomy at Anhui medical university were selected and divided into BiClamp forceps hepatectomy group and clamp-crushing hepatectomy group, each group contains 50 cases.

Results:

  1. Clinical data include: blood loss during liver transection, total blood loss, blood transfusion, hospital stay, morbidity, mortality, biliary leakage, postoperative liver function, liver transection time, operation time, resection margins, need for portal trial clamping.
  2. Statistical method: groups t-test, univariate/multivariate analysis, logistic regression analysis, mixed linear regression and Cox survival analysis were used.

What is being measured

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

  1. The Total Blood Loss

    Blood loss during operation. Blood loss was calculated from the beginning to the end of operation The amount of blood loss was measured from the suction volume after subtraction of rinse fluids and from the weight of soaked gauzes that were used during transection

    Measured: an expected average of 80 minutes

Secondary outcomes (7)
  1. Liver Transection Time

    liver transection time was calculated from the beginning to the end of the liver resection

    Measured: an expected average of 40 minutes

  2. Mortality

    Operative mortality was defined as any death resulting from a complication during surgery

    Measured: 90 days

  3. Morbidity

    Measured: 90 days

  4. Biliary Leakage

    Biliary leakage was documented in line with the International Study Group of Liver Surgery (ISGLS) definitions and grading systems

    Measured: 90 days

  5. Duration of Postoperative Hospital Stay

    Time from day of operation to day of discharge

    Measured: an expected average of 12 days

  6. Number of Participants Requiring a Blood Transfusion

    Administration of blood transfusions is documented for the intraoperative and postoperative period until 48 hours postoperatively

    Measured: 2 days

  7. Total Bilirubin

    serum total bilirubin on 3 postoperative day (umol/L)

    Measured: 3 postoperative day

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 7 inclusion and 6 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 14 Dec 2017. 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 China. 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.

What does this phase mean?

Phase 3 studies compare the treatment with the current standard treatment or a placebo in a large group, to confirm how well it works and watch for side effects.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

Yes. Results are posted in the registry (first posted 14 Dec 2017). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.

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?

The Total Blood Loss (time frame: an expected average of 80 minutes). 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 NCT02197481, which also lists 4 linked publications.

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 14 Dec 2017.
