Routine liposuction has very low perioperative complication rates and is thus
considered to be innocuous. Some authors have even proposed that large-volume
liposuction could be therapeutic. However, because subcutaneous adipose tissue
has nutritional and thermodynamic metabolic functions proportional to the
absolute amount and the distribution of fat, it is possible that removal of
subcutaneous adipose tissue might be detrimental. We measured the amount of fat
removed by large-volume (>1000 cc) liposuction and expressed the results in
terms of absolute and relative changes in total body fat and in visceral adipose
tissue (nonsubcutaneous adipose tissue) in 63 normal weight to mildly obese
women (n = 51) and men (n = 12). Aspiration of 1.5 +/- 0.7 kg (mean +/- SD) of
lipid in women removed 9.2 +/- 3.2 percent of body fat or 10.5 percent of
subcutaneous adipose tissue corresponding to a 12-percent increase in the ratio
of visceral to subcutaneous adipose tissue. One third of the women (n = 17) had
a mean increase of 16 percent (range 13 to 21 percent) in the proportion of
visceral fat. In the 12 men, aspiration of 1.7 +/- 0.6 kg of lipid removed 9.8
+/- 2.9 percent of body fat or 12.7 +/- 3.6 percent of subcutaneous adipose
tissue, resulting in a 14-percent increase in the ratio of visceral to
subcutaneous fat. The correlation between aspirate and body mass index was 0.57
(p < 0.001). Although large-volume subcutaneous liposuction removed relatively
little body fat, it led to significant increases in the proportion of visceral
adipose tissue. Because the proportion of visceral adipose tissue is a risk
factor for metabolic complications of obesity, the metabolic effects of
large-volume liposuction need to be evaluated.
