Brief summary

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.

Interventions

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.

Design outcomes

Primary

MeasureTime frameDescription
Forced Vital Capacity (FVC)8-10 minutesForced Vital Capacity will be measured before six-minute walk test according to the guideline of ERS.
Forced Expiratory Volume in 1 second (FEV1)8-10 minutesForced Expiratory Volume in 1 second will be measured before six-minute walk test according to the guideline of ERS.
Peak Expiratory Flow (PEF)8-10 minutesPeak Expiratory Flow will be measured before six-minute walk test according to the guideline of ERS.
Forced Expiratory Flow 25-75% (FEF25-75)8-10 minutesForced Expiratory Flow 25-75% will be measured before six-minute walk test according to the guideline of ERS.
mMRC Dyspnea Score8-10 minutesThe 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.
Sleep Apnea Risk Score8-10 minutesSleep 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.
Obstructive Sleep Apnea Risk Score8-10 minutesObstructive 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.
