Background: The French Society of Surgery has endorsed a cohort aiming to prospectively assess the frequency of recurrence after incisional hernia repair and to identify the risk factors.
Methods: Consecutive patients undergoing incisional hernia repair in the participating centers were included in the prospective French Society of Surgery cohort over a 6-month period. Patients were followed up with a computed tomography scan at 1 y and a clinical assessment by the surgeon at 2 years.
Results: A total of 1,075 patients undergoing incisional hernia repair were included in 61 participating centers. The median follow-up was 24.0 months (interquartile range: 14.0-25.3). The follow-up rates were 83.0% and 68.5% at 1 and 2 years, respectively. The recurrence rates were 18.1% at 1 year and 27.7% at 2 years. Recurrence risk factors at 2 years were a history of hernia (odds ratio = 1.57, 95% confidence interval = 1.05-2.35, P = .028), a lateral hernia (odds ratio = 1.84, 95% confidence interval = 1.19-2.86, P = .007), a concomitant digestive operation (odds ratio = 1.97, 95% confidence interval = 1.20-3.22, P = .007), and the occurrence of early surgical site complications (odds ratio = 1,90, 95% confidence interval = 1.06-3.38, P = .030). The use of surgical mesh was strongly associated with a lower risk of recurrence at 2 years (P < .001).
Conclusion: After incisional hernia repair, the 2-year recurrence rate is as high as 27.7%. History of hernia, lateral hernia, concomitant digestive operation, the onset of surgical site complications, and the absence of mesh are strong risk factors for recurrence.
