Despite the advantages of using internal ultrasound-assisted lipoplasty instead
of the classic tumescent lipoplasty, such as reduced bleeding and tissue damage,
the authors found no objective or comparative study of these techniques in
humans. For this reason, they conducted a clinical study to determine the amount
of bleeding and tissue damage caused by each of the techniques. A simple
clinical assay was accomplished at the Jalisco Plastic Surgery Institute on
seven female patients scheduled for abdominal lipectomy. Two similar sections of
the surgical area were marked for lipoplasty techniques: classic tumescent
lipoplasty on one side and internal ultrasound-assisted lipoplasty on the other.
Both areas were treated simultaneously by surgeons experienced in each
technique. Laboratory tests and histologic studies were performed on the
aspirated material and the manipulated tissue, respectively. The fluids sent to
the laboratory were analyzed to determine the amount of bleeding and tissue
damage. In the laboratory, the degree of lesion and tissue damage was evaluated
in the dermis, nerves, blood vessels, and adipose cells. With internal
ultrasound-assisted lipoplasty, indicators of tissue damage such as glutamic
oxalacetic transaminase, pyruvic oxalacetic transaminase, cholinesterase, and
myoglobin showed higher values than with tumescent lipoplasty. The same was
found for hemoglobin levels and in the histologic data indicative of tissue
damage; both values were statistically significant at < 0.001. Internal
ultrasound-assisted lipoplasty was not demonstrated to be more innocuous or to
have a selective effect in adipose cells, and it generally resulted in more
tissue damage and bleeding than the classic tumescent technique.
