[The use of mesh in the surgical treatment of hiatal hernias].

Primary suture repair of large hiatal hernias is associated with high recurrence rate, but the use of mesh may improve the results. There is no agreement about the ideal size, shape, or material of these mesh prosthesis, or the way those should be fixed to the crura. One of the biggest concerns of insetting a prosthetic material at the hiatus is erosion into the stomach, esophagus, or both. Cardiac injury at the time of mesh anchorage is a rare but potentially fatal complication. Introduction of biomaterials into clinical practise has completely changed the outlook of these surgical procedures.
