OBJECTIVETo evaluate the advantage and disadvantage of laser-assisted liposuction compared with conventional liposuction.

METHODSTen swines were devided into three groups, the laser liposuction group, conventional liposuction group and control group. We compared the two surgical groups with the following aspects: ecchymosi, edema, lipocrit study, hemoglobin studies and blood biochemical changes, etc.

RESULTSThere is a benefit of laser-assisted liposuction in the following aspects such as ecchymosi, edema, lipocrit and postoperative complications. The two aspects, that is, ecchymosi and lipocrit study was statistically significant. Hemoglobin change was not statistically significant between the two groups. Laser-assisted liposuction did not lead to dysfunction of organs such as liver and kidney.

CONCLUSIONSLaser-assisted liposuction can significantly decrease the blood lose, ecchymosis and edema compared with conventional liposuction, and it did not give rise to dysfunction of organs.
