Abdominoplasty With Scarpa Fascia Preservation: Prospective Comparative Study of Suction Drain Number.

[BACKGROUND] Abdominoplasty is becoming increasingly more common, with seroma being the most frequent complication. Suction drains are used very often as a method to prevent seroma formation, and it has been suggested that techniques using Scarpa fascia preservation and closed-suction drains have lower seroma rates than other approaches. However few studies have addressed parameters that may affect drain efficiency. A prospective comparative study was conducted to determine if applying 2 or 3 closed-suction drains, after an abdominoplasty with Scarpa fascia preservation, has any effect on several outcomes.

[METHODS] This was a single-center study conducted from September 2016 to March 2019. Patients were allocated according to choice to 1 of the 2 surgeons involved in the study, each responsible for 1 group: abdominoplasty with Scarpa fascia preservation with 2 closed-suction drains placed postoperatively (group A) or with 3 closed-suction drains (group B). A comparative analysis of selected variables was done between both groups, including time to drain removal, total and daily drain output, duration of hospital stay, emergency department visit, readmission to the hospital, secondary surgical procedure, and incidence of postoperative local and systemic complications.

[RESULTS] A total of 73 abdominoplasties with Scarpa fascia preservation were performed in women (group A, 33 patients; group B, 40 patients). General characteristics of group A and B were similar. There were no statistically significant differences between groups in any of the determined variables, namely, main outcomes (total and daily drain output, time to drain removal) or complications (local or systemic).

[CONCLUSIONS] Our results suggest that using 3 closed-suction drains postabdominoplasty with Scarpa fascia preservation has no advantages in total and daily drain output, time to drain removal, or complications when compared with the usual 2 drains approach.
