Comparison of Energy-Based Tissue Dissection Techniques in Abdominoplasty: A Randomized, Open-Label Study Including Economic Aspects.

[BACKGROUND] Abdominoplasty is one of the most common procedures in plastic surgery, and energy-based tissue dissection techniques have become the gold standard. Despite its frequency, abdominoplasty is still associated with high complication rates.

[OBJECTIVES] The authors compared clinical and economic data of 4 methods of energy-based tissue dissection in a randomized, open-label study.

[METHODS] A total of 57 patients were preoperatively randomized into 4 groups: electrocautery, Ultracision Harmonic Scalpel, argon plasma coagulation, and PEAK-Plasmablade. Demographic and operational data as well as information on the postoperative course and complications were collected. For economic analysis, quotes were obtained from the device companies or official suppliers.

[RESULTS] Duration of surgery, drainage quantity, and wound healing complications did not differ significantly between groups. The Ultracision method caused significantly greater blood loss compared with all other techniques (P < 0.01). PEAK and Ultracision devices entailed greater surgical costs compared with APC and electrocautery.

[CONCLUSIONS] All methods evaluated can be applied safely and effectively in abdominoplasty procedures. However, these data demonstrate a significantly higher blood loss for the Ultracision Harmonic Scalpel. Considering the clinical data, the higher costs of PEAK and Ultracision methods appear unjustified.
