摘要

Background

Abdominal dermolipectomy is one of the most frequently performed procedures in plastic surgery; however, seroma remains one of its most common complications, with reported incidences ranging from 10% to 40%. Dermoadipose fixation sutures described by Baroudi were proposed to reduce dead space and, consequently, seroma formation. Nevertheless, this technique has been repeatedly questioned due to the associated increase in operative time. This controversy underscores the need to evaluate, within our institution, the true benefits of fixation sutures on the incidence of postoperative seroma, as well as their impact on operative time and length of hospital stay.

Methods

A retrospective cohort study based on prospectively collected data was conducted, including 82 patients who underwent abdominal dermolipectomy between 2020 and 2024. Patients were divided into two groups: with flap fixation (G1, n = 52) and without fixation (G0, n = 30). The incidence of clinically significant seroma was analyzed and defined as fluid accumulation requiring aspiration.

Results

The incidence of seroma was lower in G1 (7.7%) compared with G0 (23.3%; p = 0.05). However, G1 was associated with a significantly longer operative time (233 vs. 148 min; p < 0.001).

Conclusions

Dermoadipose flap fixation significantly reduces the incidence of postoperative seroma, although it is associated with increased operative time. Level of Evidence: Level III, risk / prognostic study.
