This study aimed to evaluate the true risk of seroma with simultaneous abdominoplasty and liposuction and to assess the role of progressive tension suture in preventing it.
A retrospective chart review of 235 consecutive abdominoplasties performed by a single surgeon was conducted. Matarasso classification was used, and 146 patients with type 4 abdominoplasty were selected. These patients were divided into two groups. The 96 patients in group A had no progressive tension sutures. This group was further subdivided into subgroup A1 (43 patients), which had abdominoplasty alone, and subgroup A2 (53 patients), which had abdominoplasty with liposuction. The 50 patients in group B had progressive tension sutures. This group was further subdivided into subgroup B1 (26 patients), which had abdominoplasty alone, and subgroup B2 (24 patients), which had abdominoplasty with liposuction.
The two groups were similar in terms of body mass index, age, and smoking status. The incidence of seroma formation was 26% (n = 25) in group A, as compared with 4% (n = 2) in group B (p = 0.001). Group B showed 0% seroma formation when abdominoplasty alone was performed, as compared with 7.7% when liposuction was performed at the same time (p = 0.08, no statistical difference). Also, no statistical difference was seen when similar subgroups were compared in group A (p = 0.87).
The findings of this retrospective study show that the application of progressive tension sutures in abdominoplasty significantly reduces the incidence of seroma, and that simultaneous abdominoplasty with liposuction does not contribute to this complication.
本研究旨在评估同期行腹壁成形术和抽脂术时血清肿的真实风险，并评估渐进性张力缝合在预防血清肿方面的作用。
对由一名外科医生连续进行的235例腹壁成形术进行回顾性病历审查。采用马塔拉索分类法，选择了146例4型腹壁成形术患者。这些患者被分为两组。A组96例患者未进行渐进性张力缝合。该组进一步细分为A1亚组（43例患者），仅行腹壁成形术；A2亚组（53例患者），行腹壁成形术加抽脂术。B组50例患者进行了渐进性张力缝合。该组进一步细分为B1亚组（26例患者），仅行腹壁成形术；B2亚组（24例患者），行腹壁成形术加抽脂术。
两组在体重指数、年龄和吸烟状况方面相似。A组血清肿形成的发生率为26%（n = 25），而B组为4%（n = 2）（p = 0.001）。B组单独行腹壁成形术时血清肿形成率为0%，同期行抽脂术时为7.7%（p = 0.08，无统计学差异）。此外，A组相似亚组比较时也未发现统计学差异（p = 0.87）。
这项回顾性研究的结果表明，在腹壁成形术中应用渐进性张力缝合可显著降低血清肿的发生率，且同期行腹壁成形术和抽脂术不会增加这种并发症的发生。
