Does the mesh require fixation?

As the technique of laparoscopic mesh repair of groin hernia has evolved, the need for mesh fixation has been questioned. Staple fixation has resulted in nerve injury, and some recurrences have been attributed to the use of a mesh that is too small. Drawing on a successful experience from open preperitoneal techniques, laparoscopic surgeons are now reporting results using large mesh without fixation. Early reports show varying success with the technique. Although the problem of nerve damage has been solved, high recurrence rates are reported in which the technique has been used to repair recurrent hernias. Although further studies are required to establish the causes and natural history of mesh migration, initial experience with the technique appears promising.
