About this study
This study evaluates the safety and outcomes of combining liposuction with varying degrees of abdominal flap undermining during abdominoplasty. Patients were randomly anssigned into three groups based on the extent of undermining and use of liposuction. Outcomes assessed included complication rates, horizontal laxity, and aesthetic results.

| Study group | Role | What they receive |
|---|---|---|
| Group A: limited undermining + liposuction | Experimental | Not described Receives: Procedure: Liposuction; Procedure: Limited undermining |
| Group B: Wide undermining without liposuction | Experimental | Not described Receives: Procedure: Wide undermining |
| Group C: Wide undermining + liposuction | Experimental | Not described Receives: Procedure: Liposuction; Procedure: Wide undermining |
What is being measured
The primary outcome is the main question the study is designed to answer.
Aesthetic outcome
The postoperative aesthetic outcome was assessed using four predefined criteria by three independent surgeons in a double-blinded fashion. Each patient was assigned a postoperative score, with 1 representing the poorest outcome and 5 the best outcome. The mean score of all reviewers was then calculated for each case. These criteria included waist contour, residual adiposity (central), skin flaccidity, and the overall aesthetic appearance.
Measured: 6 months postoperatively
Postoperative complication rate (e.g., seroma, necrosis, infection)
Measured: Within 6 months postoperatively
Secondary outcomes (3)
Horizontal laxity
The "bury test" was used to assess the amount of horizontal laxity. The "bury test", almost the reverse of the pinch, involves burying the loose skin by tightly rolling the skin folds on either side of the resection area, and marking the maximum width of skin contact. This distance was measured both at rest and under tension.
Measured: 6 months postoperatively
Change in BMI
Measured: 6 months postoperatively
Epigastric pinch
The epigastric pinch was measured pre and postoperatively and difference was recorded
Measured: 6 months postoperatively

Questions about this trial
What is this clinical trial studying?
A study testing Liposuction, Wide undermining and Limited undermining in people with Abdominal Wall Viability and Abdominal Wall Laxity, run by Cairo University at 1 site in Egypt.
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 3 inclusion and 2 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 15 May 2026. 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 Egypt. 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?
Aesthetic outcome (time frame: 6 months postoperatively). The study lists 2 primary outcomes in all. 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 15 May 2026.
