Safety and Efficacy of Outpatient Drainless Abdominoplasty: A Single-Surgeon Experience of 454 Consecutive Patients.

Abstract

The incidence of seroma after abdominoplasty is accepted as approximately 10% (with a range) in the literature. Progressive tension sutures (PTS) have arisen as a means of reducing seroma, however there are conflicting data regarding their efficacy. The primary aim of this study was to describe the incidence of postabdominoplasty seroma in the setting of drainless abdominoplasty with PTS. A retrospective chart review was performed of all abdominoplasties (n = 454) during a 20-year period. At approximately the halfway point of this time frame, the abdominoplasty technique was changed from the use of 2 drains to the use of PTS without drains. Additionally, pulsed electromagnetic field therapy (PEMF) and liposomal bupivacaine (Exparel, Pacira Pharmaceuticals, Inc., Parsippany, NJ) were added as pain control adjuncts. There were 194 patients in the drain group and 260 patients in the PTS/no drains group. The group without drains contained a significantly higher proportion of massive weight loss patients (4.1% vs 9.2%, P = .041). The majority of the group without drains underwent outpatient surgery (89.7% vs 98.8%, P < .001). The overall complication rate was significantly lower in the no drains group (31.4% vs 13.8%, P < .001). The incidence of seroma was dramatically reduced in the group without drains (24.7% vs 0.0%, P < .001). PTS are highly effective in preventing seroma and can be safely employed as an alternative to drains in abdominoplasty. PEMF may play a role in seroma prevention and is also helpful for pain control. With these techniques to mitigate complications and minimize postoperative pain, abdominoplasty can be performed safely and effectively in a purely outpatient setting.
