Modified Mayo Technique for Ventral Hernia Repair: An Experimental Study.

BACKGROUND To reduce the rate of recurrence of incisional hernia repair associated with open anatomic techniques, we present an experimental study, focusing on two different sutures, with the aim to apply clinically in a revised version of the Mayo technique. METHODS Thirteen biological tissue samples from adult pig central brawn and upper and lower fasciae were measured using two techniques defined as "œunbroken suture thread" and "œseparated suture stitches" to test the breaking resistance of the two types of suture. RESULTS The t test results show that the two sets can be considered as different populations. The mean tensile stress ƒmax is greater (with reduced deviation) for the specimens of the set sutured with unbroken thread technique. Student'™s t-test performed on values obtained for each set of samples indicated that the unbroken thread suture technique corresponds to higher ultimate failure strength. CONCLUSION Considering these results, a modified Mayo technique with continuous closure could be suggested. Of course a valid clinical study is required to better clarify this experimental hypothesis.
