title: Comparison of anchoring capacity of mesh fixation devices in ventral hernia surgery.
abstract: BACKGROUND
  A reliable method of fixation of intraperitoneal mesh is required both in laparoscopic and open surgery for ventral hernia. We evaluated anchoring capacity of 3 fixation devices available for clinical use.
  
  
  METHODS
  Anchoring capacity of 3 commercially available fixation devices were compared by counting the number of sheets anchored by a single firing under a fixed pressure. A total of 5 trials were conducted for each device.
  
  
  RESULTS
  The number of sheets fixed (mean+/-SD) were, 12.4+/-1.1 for a coil type; 11.4+/-1.3 for a helical type; and 5.8+/-0.5 for a staple type tacker. The fixation capacity of the staple type was significantly lower than the other 2 types (P<0.0001). However, there was not statistically significant difference between the coil type and the helical type tackers.
  
  
  CONCLUSIONS
  The helical and coil type tackers in ventral hernia equally provide deep penetration that may contribute to strong fixation of the intraperitoneal mesh to the abdominal wall.
