Harmonic™ vs. Electrocautery in Abdominoplasties
the objective of this study is to determine if the use of The Harmonic™ (an ultrasonic surgical instrument) in abdominolipectomy (tummy tuck)reduces volume and duration of wound drainage after surgery when compared to electrocautery.

|Study Start Date:||October 2006|
|Study Completion Date:||June 2007|
Active Comparator: ELECTROCAUTERY
Elesurgical instruments are used to cut and coagulate tissue using alternatig electric current focusing intense heat at the surgical site. In electrosurgery, the patient is included in the circuit and current enters the patient's body.
Device: Ultrasonic scalpel
A surgical instrument that uses ultrasonic energy that allows both cutting and coagulating at the precise point of application.
Other Names:Device: monopolar electrosurgery generator and tip
Abdominolipectomy is performed to correct abdominal skin and fat redundancy and muscle diastases. Persistent serous wound drainage and seromas are the most common complications in abdominolipectomy. The rate of serous fluid collection determines the time drains need to remain in place. Although suction drains reduce seroma formation, prolonged use can delay healing, cause injury, and increase the risk of retrograde infection and patient discomfort. Wound drainage has a direct correlation with seroma formation. The loss of protein nutrients and minerals in the serum drained is also a concern with prolonged drainage that can result in healing delays.
The Harmonic™ technology uses ultrasonic energy that allows both cutting and coagulating at the precise point of application. The Harmonic™ has been used since 1992 predominantly in urology and gastro-intestinal surgery (laparoscopic surgery). Significantly reduced serous drainage in a number of general surgery procedures such as superficial and total parotidectomy; thyroidectomy; tonsillectomy; pectoralis major myocutaneous flap dissection; axillary dissection; and lymphadenectomy have been reported with the use Harmonic™.
The Harmonic™ has also been used in parotidectomy and maxillofacial surgery, but its use has been seldom mentioned in the field of plastic and reconstructive surgery. Recent use of the Harmonic™ has shown promise in plastic and reconstructive surgery in dissection of the pectoralis major myocutaneous flap and total body lifts.
