title: Reoperation after recurrent groin hernia repair.
abstract: OBJECTIVE
  To analyze reoperation rates for recurrent and primary groin hernia repair documented in the Swedish Hernia Register from 1996 to 1998, and to study variables associated with increased or decreased relative risks for reoperation after recurrent hernia.
  
  
  METHODS
  Data were retrieved for all groin hernia repairs prospectively recorded in the Swedish Hernia register from 1996 to 1998. Actuarial analysis adjusted for patients' death was used for calculating the cumulative incidence of reoperation. Relative risk for reoperation was estimated using the Cox proportional hazards model.
  
  
  RESULTS
  From 1996 to 1998, 17,985 groin hernia operations were recorded in the Swedish Hernia Register, 15% for recurrent hernia and 85% for primary hernia. At 24 months the risk for having had a reoperation was 4.6% after recurrent hernia repair and 1.7% after primary hernia repair. The relative risk for reoperation was significantly lower for laparoscopic methods and for anterior tension-free repair than for other techniques. Postoperative complications and direct hernia were associated with an increased relative risk for reoperation. Day-case surgery and local infiltration anesthesia were used less frequently for recurrent hernia than for primary hernia.
  
  
  CONCLUSIONS
  Recurrent groin hernia still constitutes a significant quantitative problem for the surgical community. This study supports the use of mesh by laparoscopy or anterior tension-free repair for recurrent hernia operations.
