 46 female postbariatric patients will be submitted to anchor-line abdominoplasty with drains insertion. Patients will be randomized to two groups. One group will have the Fascia Scarpa removed and in the other the Fascia Scarpa will be preserved. The drains will be removed when the volume is less than 30 ml in 24 hours. The primary outcome will be the volume of total drainage obtained in the drains of the abdominal region. Secondary outcomes will be the length of time the drains remain and the presence of seroma assessed by ultrasound on the twentieth postoperative day.
