About this study

Official title: Vacuum Assisted Wound Closure (VAWC) and Mesh Mediated Fascial Traction - Prospective Study of a Novel Technique for Open Abdomen Closure

The purpose of this multicenter trial is to prospectively evaluate a novel combination of vacuum assisted wound closure (VAWC) and mesh mediated fascial traction for closure of open abdomens.

Read the detailed description

Open abdomen treatment often results in difficulties in closing the abdomen. Highest closure rates are seen with the vacuum assisted wound closure (VAWC) technique. Failures with this technique is occasionally experienced, especially in cases with severe visceral swelling needing longer treatment periods with open abdomen. A novel combination of vacuum assisted wound closure and mesh mediated fascial traction for managing the open abdomen was therefore developed and initially tested in a small pilot-like study with encouraging results with late primary closure of the abdomens in all seven patients.

In this multicenter study we prospectively evaluate the technique.

Inclusion criteria:

All patients treated with open abdomen at the 4 participating hospitals are registered, and only those patients who have commenced therapy with VAWC and mesh mediated fascial traction will be included in the study in an intention to treat model.

Exclusion criteria:

Treatment of open abdomen with other techniques.

Method:

  • The first period of 2-5 days only the abdominal VAWC dressing is applied.
  • On day 3-10 a polypropylene mesh is sutured to the fascial edges, between the two layers of the VAWC system, and tightened.
  • The VAWC dressing is changed and the mesh tightened every 2-3 days, resulting in gradual approximation of the fascial edges.
  • Finally the mesh is removed and the fascia is closed.
  • At closure the wound to suture length is registered.

Primary endpoint:

Frequency of primary fascial closure.

Secondary endpoints:

  • study of factors associated with failure of fascial closure and in-hospital mortality,
  • abdominal pressure variation attributable to the use of the technique,
  • duration of treatment with open abdomen,
  • frequency of incisional hernia after one and five years.

Duration of the study:

3-5 years. Enrollment of open abdomen cases.

Follow-up schedule for patients:

  • Clinical evaluation at 1 and 5 years.
  • CT-examination at 1 year.

What participants receive

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

  • VAWC and mesh mediated fascial tractionProcedure or surgery

    The first period of 2-5 days only the abdominal VAWC dressing is applied. On day 3-10 a polypropylene mesh is sutured to the fascial edges, between the two layers of the VAWC system, and tightened.

    The VAWC dressing is changed and the mesh tightened every 2-3 days, resulting in gradual approximation of the fascial edges.

    Finally the mesh is removed and the fascia is closed

Questions about this trial

What is this clinical trial studying?

A study testing VAWC and mesh mediated fascial traction in people with Open Abdomen and Fascial Closure, run by Skane University Hospital at 5 sites in Sweden.

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 1 inclusion and 1 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 29 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 5 sites in Sweden. 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?

Primary fascial closure rate (time frame: 2 months). 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 NCT00494793, which also lists 2 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 29 Dec 2017.
