Surgical mesh reduces parastomal hernia risk effectively and safely.

Findings from 19 systematic reviews indicate that using surgical mesh significantly lowers the risk of both clinically and radiologically detected parastomal hernias. The pooled hazards ratio for clinically detected hernias was 0.33, while it was 0.55 for radiologically detected hernias. Additionally, mesh use was associated with a reduced need for surgical repair (hazards ratio 0.46), and overall complication rates remained similar between groups, suggesting a safe and effective intervention.
