title: Factors that affect recurrence after incisional herniorrhaphy with prosthetic material.
abstract: OBJECTIVE
  To evaluate the risk factors for recurrence after prosthetic incisional herniorrhaphy.
  
  
  METHODS
  Retrospective study.
  
  
  METHODS
  Tertiary referral centre, Spain.
  
  
  METHODS
  246 patients who had incisional herniorrhaphy with a prosthetic material (polypropylene) between 1990 and 1997
  
  
  METHODS
  A reinforcement mesh was inserted when the hernia was more than 5 cm. In incisional hernias less than 5 cm the reinforcement mesh was inserted when the repair was under tension or when tissues were noted to be weak during the operation.
  
  
  METHODS
  Age, sex, obesity, the presence of bronchial disease, previous repair of the incisional hernia, type of surgery, size and site of hernia and presence of local complications during the immediate postoperative period.
  
  
  RESULTS
  Mean (SD) follow-up was 77 (6) months (minimum follow up two years). The hernia recurred in 43 cases (17%) (mean time of recurrence 10 (8) months). Age over 60 years, previous herniorrhaphy, size of hernia, and postoperative local complications were significant risk factors (p < 0.01) in both the univariate and multivariate analyses.
  
  
  CONCLUSIONS
  Patients at the greater risk of recurrence are those aged over 60 years, with large, recurrent hernias and who develop local complications during the postoperative period.
