Laser lipolysis without suction: reality or myth?

[BACKGROUND AND OBJECTIVE] Liposuction is one of the most frequently performed aesthetic surgical procedures. Laser- and ultrasound-based systems have become especially popular in recent years, including laser lipolysis, which has a number of advantages over classic liposuction. Some researchers contend that the aspiration step is not necessary. Herein, we report a case that highlights the negative consequences when the basic surgical rule of not leaving any necrotic tissue is not followed.

[MATERIALS AND METHODS] We report the case of a 50-year-old man who presented with a 15 cm mass in the right lower quadrant, located immediately subcutaneously, passing the midline infraumbilically, tender to touch, and with beginnings of abscess formation, who underwent laser lipolysis. The subcutaneous necrotic fat was removed with a skin island en bloc. No postoperative complications occurred and the patient was problem free 6 months post-surgery.

[RESULTS] In the surgical literature, most studies on fat necrosis have focused on fat necrosis in the breast. Fat necrosis is usually a gradual process that is noticed by the patient or physician as a mass. Radiologically, it can imitate cancer, especially in breast tissue. Complications from fat necrosis are primarily linked to the amount of necrosis. Any amount of necrosis above the body's resorption capacity will lead the body into attempting self-limitation, with consequences to both the physical and psychological health of the patient.

[CONCLUSIONS] We believe that claiming that no aspiration is required after laser lipolysis, without the necessary studies, has no scientific basis.
