Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed Description

The repair of skin defects is a common problem for reconstructive surgeons.Soft tissue expansion is a widely used technique for the repair of skin defects. Early expansion-related complications such as skin thinning, telangiectasia, and striae may result in expansion failure and ultimately jeopardize final outcome. In the past years, discontinuation of the expansion procedure was the only therapeutic option, when early alarm signs such as semitransparent appearance and telangiectasia of the expanded skin were encountered. We aimed to overcome these complications by therapeutic fat grafting to prevent skin necrosis and enable continuation of the expansion procedure.

Patients undergoing soft tissue expansion treatment for resurfacing skin lesions including scars and nevi that required therapeutic intervention due to early complication signs were included in this study. Patients were randomly divided into treatment group using autologous fat grafting and control group with discontinued expansion and expectant management. The treatment group received autologous fat transfer to the expanded skin.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

18 years to 60 years (Adult)

Accepts Healthy Volunteers

No

Genders Eligible for Study

All

  • Implanted silicone expander of 50 to 800 ml in size;
  • History of deterioration in the expanded skin texture that did not improve after the inflation procedure was suspended for more than 2 weeks;
  • Persistent high level of expander internal pressure;
  • Need for further skin expansion;

Exclusion Criteria:

Arms and Interventions

Participant Group / Arm

Participant Group / Arm

A group or subgroup of participants in a clinical trial that receives a specific intervention/treatment, or no intervention, according to the trial's protocol.
Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.
Experimental: Experimental: Fat grafting
Autologous fat graft transplantation subdermally to expanded skin.
Procedure: Fat grafting
In the experimental group, liposuction will be performed and autologous fat graft will be harvest after washing with saline. Patients will receive autologous fat graft transplantation subdermally to expanded skin.
No Intervention: Control
Expansion was discontinued until the early signs of complication disappeared.

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
To Measure the Change in Expansion Volume
Time Frame: Change from baseline volume at 12 weeks
Record the volume(ml) of each expander
Change from baseline volume at 12 weeks
To Measure the Change in Skin Thickness
Time Frame: Change from baseline skin thickness at 12 weeks
Record the thickness of the expanded skin(cm) by ultrasound scanning
Change from baseline skin thickness at 12 weeks

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
To Measure the Texture of Expanded Flap with VISIA scanner
Time Frame: baseline and 12 weeks post treatment
Evaluate skin texture with VISIA scanner and compare the characteristics
baseline and 12 weeks post treatment
Occurence of Major Adverse Events
Time Frame: Up to approximately 12 weeks after study start
Including expanded flap ischaemia, necrosis, fluidify, infection, and all other adverse events
Up to approximately 12 weeks after study start

Primary Completion (Actual)

Primary Completion

The date on which the last participant in a clinical study was examined or received an intervention to collect final data for the primary outcome measure. Whether the clinical study ended according to the protocol or was terminated does not affect this date.
