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

Background: To reduce the rate of recurrence of incisionalhernia repair associated with open anatomic techniques, wepresent an experimental study, focusing on two differentsutures, with the aim to apply clinically in a revised versionof the Mayo technique.Methods: Thirteen biological tissue samples from adult pigcentral brawn and upper and lower fasciae were measured usingtwo techniques defined as “unbroken suture thread” and“separated suture stitches” to test the breaking resistance ofthe two types of suture.Results: The t test results show that the two sets can beconsidered as different populations. The mean tensile stressσmax is greater (with reduced deviation) for the specimens ofthe set sutured with unbroken thread technique. Student’st-test performed on values obtained for each set of samplesindicated that the unbroken thread suture technique correspondsto higher ultimate failure strength.Conclusion: Considering these results, a modified Mayotechnique with continuous closure could be suggested. Ofcourse a valid clinical study is required to better clarify thisexperimental hypothesis.
