Study results suggest that patients with multiple previous hernia repairs appear to be more likely that those with no previous repairs to undergo subsequent reoperations. These patients also tend to have a longer operative duration, are at greater risk for developing surgical site infections, and have higher risks for recurrence. After 140 months of follow-up, 37% of primary ventral hernias and 64% of incisional hernias had recurred among patients with previous hernia repairs. The highest recurrence rate (73%) was observed among patients undergoing at least a third repair.
