Reply, Letter to the Editor

Dear Editor,

We thank the authors of the Letter to the Editor [1] for the great interest in our publication [2] and their comments.

On comparing the recurrence rate of incisional hernia repair in sublay versus onlay technique at one-year follow-up, and following propensity score matching at 4.13% and 5.31%, no systematic disadvantage was identified for either of the two techniques [2]. The total recurrence rate was 4.23% and 5.41%. Follow-up after 1 year is, of course, much too short to permit ascertainment of the real recurrence rates.

In another analysis of data from the Herniamed Registry, we demonstrated that patients must be followed up for at least 10 years after incisional hernia repair before the recurrence rate can be definitively ascertained [3]. A systematic review with five prospective randomized trials and 17 observational studies identified recurrence rates of between 0 and 32% for the onlay technique [4]. Likewise, for the sublay technique another systematic review...
