Long-term follow-up after incisional hernia repair: Dynamics of recurrence and patient-reported outcome

Incisional hernia (IH) is common and recurrence rates remain high. Although the goal of treatment should be to improve quality of life, studies addressing this aspect are notably absent. We aimed to evaluate the long-term recurrence rate of open mesh repair of IH, investigate the burden of persisting discomfort, explore patient satisfaction, and identify risk factors for negative outcomes.

A single-center, retrospective study was conducted on all open mesh repairs of IH performed between January 2002 and October 2013. Clinical data were gathered from medical records and operative reports, while patient-reported outcome measures (PROMs) were obtained through telephone interviews. Risk factors for recurrence were assessed by survival analysis. PROMs were analyzed across patient subgroups by clinical and demographic variables.

This study included 271 patients undergoing medical record review, with 136 patients completing the telephone interview. Recurrence rates at 2, 5, 10, and 15 years were 6%, 8%, 11%, and 12%, respectively. Risk factors for recurrence were obesity and an estimated mesh-defect overlap <7 cm. Bridged repair posed no increased risk. For PROMs, the median follow-up time was 13.6 years after which 78.7% of the patients reported no discomfort, and 89.0% were satisfied with their surgery. Patients <65 years and females experienced more long-term discomfort.

Recurrence rates were higher in obese patients and when the estimated mesh-defect overlap was <7 cm, but not in bridged repairs. Young patients and females are at increased risk for long-term discomfort. High satisfaction levels were reported.
