[Lipoemulsification. A histological study on the action of ultrasound, access site and adipose tissue].
A new mini-invasive technique for the lysis of subcutaneous adipose tissue has emerged in recent years. This directly applies ultrasounds to the tissue by titanium probes. Ultrasounds act on parenchyma tissues, saving the structure and integrity of the blood vessels. Our study show histological features of the subcutaneous adipose tissue evolution just ultrasound-treated up to 30 days after surgery. Five obese female patients underwent the treatment by anesthesia. Before surgery the sites to treat were topically injected with sterile, hypotonic, apyrogen saline solution added with adrenaline, Biopsies have been taken intraoperatively from the border cutis of the holes made for the introduction of the titanium probes and from the subcutaneous adipose tissue. Biopsies have also been taken during a follow-up at 2, 5, 15 and 30 days postoperatively. Drains were positioned in the treated sites for at least 72 hours. The same sites were sutured so at to make later follow-up biopsies easier. Histological specimens were considered according to three dying methods: eosin-haematoxylin, Gomori and acetic orcein. We observed, as a confirmation the safety of the adipose tissue blood vessels, and the substitution of the destroyed adipose tissue with a microfibrillar connective tissue not subject to a sclerogenic evolution.
