Abstract

Background: Surgical groin wounds are at risk of delayed healing and infection, leading to costly and prolonged postoperative recoveries. This study assesses the use of closed suction drains (CSDs) as a wound care adjunct in groin incisions to prevent surgical site infections (SSI).

Methods: A single-center retrospective review was performed on 210 consecutive patients after vascular surgery with common femoral artery exposure from 2016 to 2021. The cohort was divided into 2 groups, groins with and without CSD, looking for surgical site complications. A subgroup analysis comparing postoperative outcomes between complicated and uncomplicated groin incisions within both groups was also performed.

Results: Of 293 surgical groins, 20% (n = 59) had drains. Overall, the CSD group had higher SSI rates (14% vs. 5.6%), but also had higher proportion of smokers (92% vs. 83%; P = 0.019), diabetes (56% vs. 36%; P = 0.005), coronary artery disease (69% vs. 46%; P = 0.001), hyperlipidemia (69% vs. 51%; P = 0.01), and previous groin surgery (54% vs. 17%; P < 0.001). The higher risk of SSI was not significant after adjustment of these confounders. A separate analysis within each group showed SSI groins with CSD had lower reintervention rates (37.5%) than those without CSD (69%), as well as shorter length of hospital stay (7 [5-11] vs. 22 [7-25] days).

Conclusions: Our study suggests that CSDs can be a beneficial adjunct for groin wounds after common femoral artery exposure in patients with comorbidities cited above. CSDs decrease the risk of reintervention and length of hospital stay.
