Incisional hernia recurrence following ''vest-over-pants'' or vertical mayo repair of primary hernias of the midline

A series of 68 primary midline incisional hernias with a vertical Mayo repair was evaluated retrospectively. Patients without documented hernia recurrence following this repair were invited for physical examination. Life-table methods were used for statistical analysis. The 1-, 3-, 5-, and 10-gear cumulative recurrence rates were 35%, 46%, 48%, and 54%, respectively. Also, generally accepted risk factors were studied. Multivariate analysis identified the size of the hernia (p = 0.02) and the use of steroids (p = 0.04) as the most important independent risk factors of first time recurrent incisional hernia. Considering the high recurrence rates found, the results of this study strongly suggest that the vest-over-pants repair should no longer be used for closure of midline incisional hernias.
