Abstract
BACKGROUND: Drain practices in minimally invasive retromuscular ventral hernia repairs have largely been transferred over from open surgery without significant review. We wished to evaluate the role of drains in these repairs. METHODS: Using the Abdominal Wall Reconstruction Surgical Collaborative (AWRSC) registry, patients with ventral hernias who underwent enhanced-view totally extraperitoneal (eTEP) repairs between February 2016 and September 2019 were evaluated. Patients with contamination or active infection within the surgical field, those who underwent an emergent or hybrid repair, or received a concomitant procedure were excluded. Propensity score matching based on the defect size, previous hernia repair status, and the use of posterior component separation (PCS) was used to match patients with drains to patients without drains. We evaluated 180-day outcomes in terms of SSIs, SSOs, and recurrence. RESULTS: 308 patients met the inclusion criteria. After propensity score matching, 48 patients with drains and 72 without drains were included in the analysis cohort. Those with drains were older with a greater likelihood of an incisional hernia, but were broadly similar for other relevant demographic and hernia-related variables. While there was no difference in the incidence of SSOs and SSIs between the two groups, we report a higher risk of SSOs needing procedural intervention (SSOPI) and recurrence, with a lengthened hospital stay in the cohort that received surgical drains. CONCLUSION: The use of surgical drains in "clean" eTEP repairs of ventral hernias appears to be common, with a selection bias for more complex cases. Based on our analysis, we found the use of drains was associated with longer hospital stays. The use of drains did not change the likelihood of suffering an SSI or SSO. However, the incidence of SSOPIs was higher despite the use of drains, which raises questions about their protective role in these repairs.
