title: Prospective randomized study of stapled versus unstapled mesh in a laparoscopic preperitoneal inguinal hernia repair.
abstract: BACKGROUND
  In 1975, researchers introduced the use of a large unsutured polyester mesh prosthesis placed in the preperitoneal space for inguinal hernia repair. Different stapling devices have been used to secure this mesh, and the most common complication of the procedure is nerve damage secondary to the staples. The necessity of stapling has never been demonstrated. We designed a prospective randomized study of the need for stapling in laparoscopic extraperitoneal repair of inguinal hernias with 1-year and 3-year followup.
  
  
  METHODS
  Inclusion criteria of the study were men older than 18 years and first-time inguinal hernia repair. Patients with recurrence and previous abdominal operations were excluded to avoid confounding variables. Each patient's hernia was assigned a consecutive random number chosen by computer, with each number corresponding to an assigned group. The first group had stapled mesh and the second had unstapled mesh.
  
  
  RESULTS
  Data were collected over a 15-month period, with each procedure having a mean followup time of 8 months. A total of 100 procedures was performed in 92 patients. The two groups of patients were well matched for age and the type of hernia repaired. There were no recurrences in either group and no complications or deaths.
  
  
  CONCLUSIONS
  The initial 12-month followup showed no significant differences in recurrence or complication rates between the stapled and unstapled groups. Both groups returned to work within an average of 4 days. A net savings of $120 was realized for each hernia repair performed without stapled mesh. In addition, stapling presents an inherent risk of nerve damage.
