title: DIEP flap donor site versus elective abdominoplasty short-term complication rates: a meta-analysis.
abstract: BACKGROUND
  Although over the past decade the DIEP flap has emerged as one of the preferred choices for autologous breast reconstruction and the donor-site closure has much in common with the standard abdominoplasty technique, reports on comparisons of the complication rates between DIEP and elective abdominoplasty patients are not currently available. The purpose of this study was to compare DIEP donor-site and elective abdominoplasty short-term complications rates, in support of surgical choices.
  
  
  METHODS
  Searches of MEDLINE and CENTRAL for English language articles on DIEP and elective abdominoplasty (EA) published from January 1999 through December 2009 identified 33 studies that met the inclusion criteria and included 3,937 patients. A random-effects model was used to calculate the average complication rate in the literature.
  
  
  RESULTS
  The rate of seroma/hematoma in EA (16.1%, 95% confidence interval [CI] = 12.2-20.9%) was approximately four times the rate in DIEP flap patients (3.7%, 95% CI = 1.5-8.8%) was found from analyzing the data under a random-effects model. No substantial differences in the rates of infection, abdominal/umbilical necrosis, or wound dehiscence/delayed healing between the two series of patients were detected.
  
  
  CONCLUSIONS
  This meta-analysis reveals that DIEP donor-site complication rates were comparable to those in elective abdominoplasty, and, the rate of seroma in DIEP is an even lower than that of one of the most performed procedures in plastic surgery. We argue that patients presenting for a DIEP flap should be informed about this interesting comparison.
