Background: Incisional hernias (IH) are a complication of abdominal surgeries. Hernia rates may vary by patient and abdominal surgery type, and some hernias may require additional surgeries to repair. Meshes have historically been used during hernia repair to prevent recurrence; however, prophylactic mesh during the initial abdominal closure following abdominal surgery in high-risk patients may prevent hernias.

Objectives: The purpose of this literature review was to assess the clinical outcomes of prophylactic mesh during the initial abdominal closure following high-risk abdominal surgeries.

Methods: We performed a targeted literature search with a key word search using PubMed, Embase, and Cochrane Central Register of Controlled Trials (2008–2018).

Results: A total of 72 studies conducted in 19 countries assessed clinical outcomes associated with prophylactic mesh. In patients undergoing high risk abdominal surgery, permanent synthetic-mesh closure was associated with a significant reduction (p<0.05) [bariatric: 25%-26% reduction, abdominal aortic aneurysm (AAA): 17%-28%, emergency: 25%-27%, stoma reversal: 14%-30%, stoma creation: 15%-44%] in hernia rates vs. non-mesh closure. Biologic mesh was associated with a significant reduction (p<0.05) (bariatric: 15%, AAA: 32%, stoma creation: 16%-54% depending on detection method) in hernia rates vs.  no-mesh.  36 of 42 studies that compared complications (ie wound infections, SSI and seroma) reported similar complication rates. In 4 studies, mesh had significantly higher complications and in 2 studies, significantly lower complications.

Conclusion: Among patients undergoing high risk abdominal surgery, prophylactic mesh was associated with reduced IH occurrence. Results suggest that mesh could be a useful prophylactic tool for clinicians during certain abdominal closure procedures.
