The impact on a lipids metabolism of a certain volume of fat tissue extraction from organism was investigated. With that objective there was determined the lipids content in a blood serum before and on a 14th day after abdominoplasty. In 73 patients (the main group) surgical interventions were performed on the organs of abdominal cavity, small pelvis and anterior abdominal wall with a simultant abdominoplasty, in 59 patients (a comparison group) abdominoplasty was not performed. The lipids metabolism desorders was observed in both groups of patients. The results of operations, conducted with a simultant extraction of a fat tissue were characteristic for positive dynamics of the lipids spectre in the blood. A normalizing impact on the blood serum lipids was caused by a triglyceride depot volume reduction, which promotes a catabolism processes strengthening in atherogenic lipoproteins and stabilizes a nonesterified fat acids concentration on optimal level. The data obtained witness, that abdominoplasty conduction secures antiatherogenic affect in patients, suffering obesity.
