About this study

Official title: Laparoscopic Aortic Surgery: Norwegian Experiance

Patients with aorto-iliac occlusive disease (TASC, type D) operated with a totally laparoscopic aortobifemoral bypass operation and open aortobifemoral bypass operation will be followed up and the results will be compared between the two procedures on the basis of the primary endpoint, a composite endpoint defined as a combined incidence of systemic morbidity, graft thrombosis and all-cause mortality.

Read the detailed description

Patients with aorto-iliac occlusive disease (TASC, type D) operated with a totally laparoscopic aortobifemoral bypass operation and open aortobifemoral bypass operation will be followed up and the results will be compared between the two procedures on the basis of the primary endpoint, a composite endpoint defined as a combined incidence of systemic morbidity, graft thrombosis and all-cause mortality.

Secondary endpoints like length of hospital stay, operation time, bleeding time shall also be considered.

Besides short form- 36 (SF-36) shall be used for the evaluation of patients health related quality of life, preoperatively,1,3,and 6 months and 1 year post-operatively.

Early, midterm and long time results shall be followed.

What is being measured

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

  1. Composite endpoint (All-cause mortality, graft occlusion and systemic morbidity)

    Composite endpoint defined as all-cause mortality, systemic morbidity and graft thrombosis.

    In this prospective comparative cohort study 50 consecutive patients with type D atherosclerotic lesions in the aortoiliac segment were treated with laparoscopic aortobifemoral bypass operation. The group was compared with 30 patients operated with open aortobifemoral bypass operations for the same disease and period of time. The groups were compared on the basis of composite endpoint All-cause mortality, graft occlusion and systemic morbidity). Stratification analysis was performed by using Mantel-Haenszel method with the patient time model. Cox multivariate regression method was used to adjust for confounding effect after considering the proportional hazard assumption. Cox proportional cause-specific hazard regression model was used for competing risk endpoints. Comparison of survival curves was done with the help of log- rank test.

    Measured: 2005-2015

Secondary outcomes (1)
  1. Operative time, operative bleeding, length of hospital stay, quality of life

    Linear regression model was used to control for the confounding effect of the secondary continuous outcomes.

    Measured: 2005-2015

Questions about this trial

What is this clinical trial studying?

An observational study of Aorto Iliac Occlusive Disease, run by Oslo University Hospital at 1 site in Norway.

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 0 inclusion and 1 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Where is the study taking place?

The record lists 1 site in Norway. 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?

Composite endpoint (All-cause mortality, graft occlusion and systemic morbidity) (time frame: 2005-2015). 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 NCT01259908, 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?
