Three types of minimally invasive ventral herniorrhaphies were perform
ed in eight patients: primary repair with sutures (1 case), single-lay
er prosthesis repair with polytetrafluoroethylene (4 cases), and bilay
er prosthesis repair with polytetrafluoroethylene and polypropylene (3
cases). One patient undergoing the bilayer repair developed a small h
ematoma in the subcutaneous tissue at the site of the repair, which re
solved without intervention. There were no other complications, and no
recurrence was noted in follow-up of 14 to 20 months.
