title: Prospective clinical study of 551 cases of liposuction and abdominoplasty performed individually and in combination.
abstract: BACKGROUND
  Despite the popularity of these procedures, there are limited published prospective studies evaluating liposuction and abdominoplasty. Lipoabdominoplasty is a subject of recent attention. Several investigators have recommended alternative techniques that preserve the Scarpa fascia in an effort to reduce complications, particularly the risk of seromas.
  
  
  METHODS
  Over a 5-year period, 551 consecutive patients were treated with ultrasonic liposuction alone (n = 384), liposuction/abdominoplasty (n = 150), or abdominoplasty alone (n = 17). In lipoabdominoplasties, the abdomen and flanks were first treated with liposuction. A traditional flap dissection was used for all abdominoplasties. Scalpel dissection was used rather than electrodissection. A supine "jackknife" position was used in surgery to provide maximum hip flexion, allowing a secure deep fascial repair.
  
  
  RESULTS
  The complication rate after liposuction was 4.2% vs 50% for patients treated with an abdominoplasty. Approximately half of the abdominoplasty complications were minor scar deformities, including widened umbilical scars (17.3%) that were revised. The seroma rate after abdominoplasties was 5.4%; there were no seromas after liposuction alone.
  
  
  CONCLUSIONS
  Lipoabdominoplasty may be performed safely, so that patients may benefit from both modalities. The seroma rate is reduced by avoiding electrodissection, making Scarpa fascia preservation a moot point. A deep fascial repair keeps the abdominoplasty scar within the bikini line. Deep venous thrombosis and other complications may be minimized with precautions that do not include anticoagulation.
