Liposuction surgery is common, yet animal and limited human data suggest that fat returns when removed. We undertook a 1-year randomized-controlled trial of suction lipectomy versus no intervention to determine if adipose tissue is defended, and if so to determine the anatomic pattern of redistribution.

Condition Intervention
Disproportionate Shape Created by Expanded Fat Pads.
Procedure: Liposuction

Study Type: Interventional
Study Design: Allocation: Randomized
Intervention Model: Parallel Assignment
Masking: Open Label
Primary Purpose: Treatment
Official Title: Mechanisms Defending Fat Mass in Humans After Lipectomy

Detailed Description:

Specific Aims:

  1. To determine if suction lipectomy fails to modify regional and/or total body fat over three years.
  2. To determine if the expression of candidate genes predicts and/or relates to subcutaneous adipose tissue growth or depletion in subcutaneous adipose tissue after suction lipectomy.
  3. To examine adipose tissue before and after suction lipectomy to uncover novel genes where expression predicts and/or relates to subcutaneous adipose tissue growth or depletion after subcutaneous suction lipectomy.

Ages Eligible for Study:   18 Years to 50 Years
Genders Eligible for Study:   Female
Accepts Healthy Volunteers:   Yes

Inclusion Criteria:

  • Eligible premenopausal women were between the ages of 18-50 years with a BMI of 22-27 kg/m2 at their maximum body weight and weight stable for at least 3 months. Weight stability was defined as a <5-7% change from the maximum weight over 3-6 months. In addition, participants were non-smokers with no history of glucose intolerance, dyslipidemia, liver, kidney and cardiac disease, hypertension, cancer or any other chronic debilitating disorder that might have interfered with a 'normal' lifestyle (nutrition, physical activity). Women on thyroid hormone replacement with a normal TSH were included. Oral contraceptives were acceptable if the woman remained on therapy throughout study participation.

Exclusion Criteria:

  • Further exclusions included: reduced-obese, defined as history of obesity and weight loss >10% of maximum body weight, or of liposuction or gastric bypass surgery; evidence of body dysmorphic disorder; taking sex steroids, glucocorticoids, or medications affecting carbohydrate and lipid metabolism; hematocrit, hemoglobin, WBC, platelet count, liver or renal function tests out of the normal range; fasting plasma glucose >110 mg/dL; triglycerides >200 mg/dL; HDL cholesterol <35 mg/dL and LDL cholesterol >160 mg/dL; proteinuria; blood pressure >140/90 mm/Hg; electrocardiogram abnormalities. People with a history of claustrophobia, or who had any placement of metal implants or a history of internal metal fragments were evaluated by the radiologist prior to inclusion.
