The results of a nationwide survey regarding the treatment of incision
al hernias following open laparotomy revealed that the Mayo-duplicatio
n is the surgical technique preferred by the majority of surgeons. How
ever, in exceptional situations alloplastic material is implanted by u
p to 50 % of the surgeons asked. More than one forth of the department
s performed more than 30 incisional hernia repairs per year. Even for
complicated cases the surgeons' own estimation of their recurrence rat
es was 11.7 %. Compared with the data (recurrence rate of the Mayo-dup
lication of 30 %-50 %) published in the literature there seems to be a
quantitative and qualitative underestimation of the treatment of inci
sional hernias.
