title: Risk factors for parastomal hernia: based on radiological definition.
abstract: OBJECTIVE
  The aim of this study was to investigate the clinical and radiological incidence of parastomal hernia and to analyze the risk factors for parastomal hernia.
  
  
  METHODS
  We reviewed retrospectively 108 patients with end colostomy from January 2003 to June 2010. Age, sex, surgical procedure type, body mass index (kg/m(2)), stoma size, and respiratory comorbidity were documented.
  
  
  RESULTS
  There were 61 males (56.5%) and 47 females (43.5%). During an overall median follow-up of 25 months (range, 6 to 73 months), 36 patients (33.3%) developed a radiological parastomal hernia postoperatively and 29 patients (26.9%) presented with a clinical parastomal hernia. In multivariate analysis, gender (odds ratio [OR], 6.087; P = 0.008), age (OR, 1.109; P = 0.009) and aperture size (OR, 6.907; P < 0.001) proved to be significant and independent risk factors after logistic regression analysis.
  
  
  CONCLUSIONS
  This study showed that the incidence of radiological parastomal hernia is higher than clinical parastomal hernia. Risk factors for parastomal hernia proved to be female, age, and aperture size.
