title: Recurrence after surgery for varices in the  groin is not dependent on body mass index.
abstract: OBJECTIVE
  To investigate if the body mass index (BMI) differs between different groups of patients (incomplete ligation also defined as technical error, neo-revascularisation, uncertain and mixed) in recurrent same site inguinal varices after surgery (REVAS).
  
  
  METHODS
  During a six and half year time span, we retrospectively analysed 203 consecutive procedures in 153 patients undergoing recurrent same site vein surgery in the groin. Individual BMI was calculated and compared within the different REVAS nature of the source groups.
  
  
  RESULTS
  The median BMI was 28 for patients undergoing recurrent vein surgery in the groin with no relevant difference in BMI between the different source groups (confidence interval for the difference of adjusted group means equals [-1.5, 2.6]).
  
  
  CONCLUSIONS
  There is no relevant difference in BMI between the two commonest REVAS groups. This may be due to small sample size, but confidence limits for difference of.
