Actual (reported)This study investigates the long-term effects of lipoabdominoplasty on pulmonary function and obstructive sleep apnea (OSA) risk in obese patients. Participants were evaluated before and three months after surgery using spirometry, mMRC dyspnea scores, Epworth Sleepiness Scale (ESS), and STOP-Bang questionnaires.

Obese subjects undergoing lipoabdominoplasty
Combination of liposuction and abdominoplasty under general anesthesia. Klein solution used for tumescent liposuction. Muscle plication performed with 0 loop polydioxanone suture. Umbilicus preserved and repositioned. Postoperative compression corset used for 1 month.
Registry-reported names are shown in full. Names without a link have not yet been matched to a Syfrah profile.
This prospective observational study will include adult patients (18-65 years) with a body mass index (BMI) over 30 kg/m² who are scheduled to undergo lipoabdominoplasty at a single tertiary care center. Eligible participants will be evaluated prior to surgery and again at 3 months postoperatively. Individuals with active pulmonary infections, chronic lung diseases, recent additional surgeries, or pregnancy will be excluded. All participants will provide written informed consent before enrollment. Approximately 24 participants are expected to complete both baseline and follow-up assessments.

Actual (reported)Novel Inhibitors of Lipolysis in the Treatment of Lipid a Glucose Metabolism in Obstructive Sleep Apnea Syndrome
mMRC Dyspnea Score
The dyspnea score will be assessed with the mMRC dyspnea score and is based on five stages of dyspnea caused by exertion and is scored between 0-4.
8-10 minutes
Sleep Apnea Risk Score
Sleep apnoea risk will be assessed using the Epworth Sleepiness Scale (ESS), a validated 8-item questionnaire that measures the subject's likelihood of falling asleep during daily activities. Higher scores reflect greater levels of daytime sleepiness and increased risk for conditions such as obstructive sleep apnoea.
8-10 minutes
Obstructive Sleep Apnea Risk Score
Obstructive sleep apnoea risk will be assessed assessed using the STOP-Bang questionnaire, an eight-item screening tool that evaluates snoring, tiredness, observed apnoea, high blood pressure, BMI, age, neck circumference, and gender. A higher score indicates a greater risk of OSA, with a cut-off of ≥3 commonly used to identify high-risk individuals.
