title: Postmortem computed tomographic (PMCT) demonstration of the relation between gastrointestinal (GI) distension and hepatic portal venous gas (HPVG).
abstract: OBJECTIVE
  The purpose of this study was to investigate the relation between gastrointestinal (GI) distension and hepatic portal venous gas (HPVG) on postmortem computed tomography (PMCT).
  
  
  METHODS
  Our subjects were 190 PMCT obtained within two hours of non-traumatic death [175 patients underwent cardiopulmonary resuscitation (CPR) and 15 patients did not undergo CPR]. We evaluated the incidence and location of GI distension (0 = no distension, 1 = stomach and duodenum, 2 = more distal than 1) and HPVG (0 = no gas, 1 = left lobe, 2 = 1 + right anterior lobe, 3 = 2 + right posterior lobe).
  
  
  RESULTS
  GI distension (grade 0/1/2 = 58/55/62 patients) and HPVG (grade 0/1/2/3 = 114/10/ 28/23 patients) were observed in 175 patients who underwent CPR. The grade of HPVG increased significantly in accordance with the advancement of GI distension. Fifteen patients without undergoing CPR showed no GI distension but one patient showed grade 1 HPVG.
  
  
  CONCLUSIONS
  PMCT indicates the presence of a relation between GI distension and HPVG.
