title: Trocar site hernia after laparoscopic cholecystectomy.
abstract: OBJECTIVE
  The aim of this study was to elucidate the influence of pre and perioperative factors on the development of trocar site hernia after a laparoscopic cholecystectomy procedure.
  
  
  METHODS
  A total of 776 patients who underwent a laparoscopic cholecystectomy procedure in our Department of General Surgery between 1999 and 2004 were assigned as the study group. The control group included patients without trocar site hernias after a cholecystectomy. The effect of five variables, including gender, age, body mass index (BMI), operation duration, and the type of cholecystitis on the development of a trocar site hernia after a laparoscopic cholecystectomy was assessed by univariable and multivariable models.
  
  
  RESULTS
  In the univariate analysis, female gender (P = 0.021), older age (P < 0.001), higher BMI at the time of surgery (P < 0.001), and an increased duration of surgery (P < 0.001) have been found to increase the likelihood of a trocar site hernia formation. However, in the multivariable model, the gender was not a significant variable to influence the development of this complication.
  
  
  CONCLUSIONS
  The development of a postoperative trocar site hernia may be prevented by the closure of 10-mm trocar sites in patients who are older than 60 years, obese, and who have a longer duration of operation.
