Technique for introducing large composite mesh while performing laparoscopic incisional hernioplasty.

Background: Incisional hernias are treated laparoscopically in an increasing number of cases. The simplest technique is the peritoneal onlay technique. Composite mesh, consisting of one layer of polypropylene mesh, destined to face the abdominal wall, and one layer of less adhesion-inducing material, destined to face the bowel, has been developed in an effort to avoid intraperitoneal adhesion formation and viscus erosion. While probably superior, this type of mesh is very bulky, easily damaged, and hence extremely difficult to be safely introduced through conventional trocars.
Methods: We present a simple technique to safely introduce intraperitoneally large sheets of composite mesh, without the need for larger-bore cannulas. After temporarily removing one of the 10 mm trocars, the mesh is rolled as tightly as possible and placed in a sterile bag, which is then easily introduced intraperitoneally through the trocar opening.
Results: Between September 1999 and January 2000 the technique was successfully used in 12 patients.
Conclusion: This simple trick protects the mesh while making its intraperitoneal introduction straightforward. It is quick, cheap, and easily reproducible.
