Reduced Seroma Risk in Drainless Abdominoplasty Using Running Barbed Sutures: A 10-Year, Multicenter Retrospective Analysis.

[BACKGROUND] Drains are still commonly inserted during abdominoplasties despite extensive evidence documenting the benefits of drainless procedures. Continued improvements in progressive tension suturing (PTS) techniques and suture technologies have consistently shown a reduced seroma risk profile that outperforms procedures involving surgical drains.

[OBJECTIVES] The aim of this report was to assess the authors' combined patient series, which represents the largest and longest-running, retrospective, multicenter set of abdominoplasty patients treated with a PTS technique involving running barbed sutures.

[METHODS] Two surgical groups, each at different surgical centers, have for the past decade performed drainless abdominoplasties in which running barbed sutures were used. The results for all 445 patients in this series are reported by surgical center and pooled across centers.

[RESULTS] The majority of the 445 patients underwent drainless abdominoplasty alone (n = 368; 82.7%); most of the remaining patients did so as part of a circumferential body lift (n = 55; 12.4%). Overall, 33 (7.4%) patients experienced a postoperative complication. The overall seroma rate was 4.7% (21 of 445 patients), but this dropped to 2.3% after surgical technique modifications were made to decrease upper abdominal dead space. The seroma incidence in this series is markedly lower than the 13% seroma rate with drains reported during the same time period and comparable to those seen in drainless abdominoplasties with interrupted suture techniques.

[CONCLUSIONS] Drainless abdominoplasty involving PTS with running barbed sutures shows long-term reproducibility in lowering seroma risk compared to techniques in which drains are inserted, supporting results from published series of drainless abdominoplasty procedures that use interrupted suture techniques.
