Evaluation of the Number of Progressive Tension Sutures Needed to Prevent Seroma in Abdominoplasty with Drains: A Single-Blind, Prospective, Comparative, Randomized Clinical Trial

Background Seroma formation has become the most reported complication after abdominoplasties. In 2000, progressive tension sutures (PTS) were described and reported to be associated with a seroma rate of 0.1%. Surgeons worldwide use PTS to prevent seroma; however, there are discrepancies in the number of PTS commonly used, starting from five up to 35 sutures. The absence of standardization may cause a lack of seroma prevention, increased surgical time, and general hesitation to perform the technique.
