PURPOSE
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).
MATERIALS AND 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.
CONCLUSION
PMCT indicates the presence of a relation between GI distension and HPVG.
目的
本研究旨在探讨尸检计算机断层扫描（PMCT）中胃肠道（GI）扩张与肝门静脉积气（HPVG）之间的关系。
材料与方法
我们的研究对象为190例非创伤性死亡后两小时内进行的PMCT（175例患者接受了心肺复苏（CPR），15例患者未接受CPR）。我们评估了胃肠道扩张的发生率和部位（0 = 无扩张，1 = 胃和十二指肠，2 = 比1更靠远端）以及肝门静脉积气情况（0 = 无气体，1 = 左叶，2 = 1 + 右前叶，3 = 2 + 右后叶）。
结果
在接受CPR的175例患者中观察到胃肠道扩张（0/1/2级 = 58/55/62例患者）和肝门静脉积气（0/1/2/3级 = 114/10/28/23例患者）。肝门静脉积气的分级随着胃肠道扩张程度的加重而显著增加。15例未接受CPR的患者未出现胃肠道扩张，但有1例患者出现1级肝门静脉积气。
结论
PMCT显示胃肠道扩张与肝门静脉积气之间存在关联。
