title: Can radio-opaque markers be used to measure mouth-to-stoma transit time in ileostomates?
abstract: OBJECTIVE
  To determine whether radio-opaque markers can be used to assess mouth-to-stoma transit time (MSTT) in ileostomates.
  
  
  METHODS
  Criterion standard.
  
  
  METHODS
  Metabolic research unit.
  
  
  METHODS
  Five volunteer ileostomates.
  
  
  RESULTS
  MSTT assessed by radio-opaque markers (11.3 to 12.5 h) was significantly longer (P < 0.5) than that calculated by ileal recovery of dietary starch (6.5 to 8.8 h), the criterion standard.
  
  
  CONCLUSIONS
  Radio-opaque markers are unsuitable for measurement of MSTT in ileostomates.
