Abstract
PURPOSE: The concept of mesh use during open ventral hernia repair with a concomitant intestinal procedure remains controversial and it remains unclear whether the SSI profile of contaminated fields in this setting more closely resembles clean-contaminated or dirty wounds. METHODS: Patients who underwent an open ventral hernia repair and intestinal procedures were extracted from the ACS-NSQIP database. Data analysis was performed for mesh versus no mesh groups in aggregate and matched cohorts. The 30-day outcomes including mortality, morbidity, surgical site infections (SSI), readmission, reoperation, and length of stay were compared between the groups. RESULTS: Of 5104 patients in the mesh group, 3297 patients were matched 1:1 with patients without mesh. Mesh placement was associated with higher overall morbidity (35.1% vs. 29.8%; p < 0.001), overall SSI (27.1% vs. 18%; p < 0.001), deep SSI (5.9% vs. 4.3%; p = 0.003), organ-space SSI (6.8% vs. 5.5%; p = 0.027), reoperation (9.9% vs. 8.2%; p = 0.016), readmission (16.7% vs. 12.7%; p < 0.001), and longer hospital stays (10.9 ± 15.2 vs. 9.7 ± 10.7; p < 0.001). When mesh was used, the SSI profile of contaminated fields was similar to dirty wounds (26.4% vs. 27.5%; p = 0.702), rather than clean-contaminated fields (26.4% vs. 19.2%; p < 0.001). CONCLUSION: Concomitant bowel procedure and mesh placement at the time of open ventral hernia repair was associated with worse outcomes. The SSI profile of the contaminated fields was more similar to dirty wounds. When deciding whether to place mesh during ventral hernia repairs with concomitant bowel procedures, strong consideration should be given to the increased risk of short-term complications versus the potential long-term benefits.
