title: Seroma in lipoabdominoplasty and abdominoplasty: a comparative study using ultrasound.
abstract: BACKGROUND
  Abdominoplasty is one of the most frequently performed cosmetic procedures, and its combination with liposuction has become more common. Seroma is one of the most common complications in abdominoplasty. The aim of this study was to compare the rate of seroma formation in patients who underwent either abdominoplasty with or without the use of quilting sutures or lipoabdominoplasty.
  
  
  METHODS
  Fifty-eight female patients were divided into three groups and underwent one of the following procedures: group A (n=21), abdominoplasty without quilting sutures; group B (n=17), abdominoplasty with quilting sutures; and group C (n=20), lipoabdominoplasty. To investigate seroma formation, abdominal ultrasound was performed in five regions of the abdominal wall (epigastrium, umbilical, hypogastrium, right iliac fossa, and left iliac fossa) at two postoperative periods (P1, between postoperative days 11 and 14; and P2, between postoperative days 18 and 21).
  
  
  RESULTS
  The rate of seroma formation at both P1 and P2 was significantly higher in group A. It was observed that in group A at P1, the regions of right iliac fossa and left iliac fossa developed larger fluid collections. In group B, there were no significant differences with respect to fluid collections among the five study regions at both P1 and P2. In group C, there were significantly larger fluid collections in the hypogastrium region at P1 and in the umbilical and hypogastrium regions at P2.
  
  
  CONCLUSIONS
  Abdominoplasty with quilting sutures and lipoabdominoplasty are effective techniques for the prevention of seromas compared with abdominoplasty without quilting sutures.
