title: Petit lumbar hernia--a double-layer technique for tension-free repair.
abstract: This report describes an alternative technique for Petit hernia repair. The treatment of lumbar hernias should follow the concept of tension-free surgery, and the preperitoneal space can be the best place for prosthesis placement. An obese patient had a bulge in the right lumbar region, which gradually grew and became symptomatic, limiting her daily activities and jeopardizing her quality of life. She had previously undergone 2 surgical procedures with different incisions. We created a preperitoneal space and attached a mesh in this position. Another prosthesis was placed on the muscles, with a suitable edge beyond the limits of the defect. There were no complications. It has been described as a safe and tension-free repair for Petit hernia. In larger defects, a second mesh can be used to prevent further enlargement of the triangle and also to provide additional protection beyond the bone limits.
