Reddish-purple areas occasionally found on the surface of the liver have been related to peliosis hepatis. The purpose of the present study was to determine: 1) the frequency of these changes in a total of 3035 laparoscopies and 2) the histological substrate of these laparoscopical changes. In 20 cases (0.65%), reddish-purple patches of round, triangular, star-shaped or net-work configuration were found on the liver surface. Liver biopsies taken from these areas showed: 1) dilatation of sinusoids; 2) blood-filled cavities, and 3) intralobular hemorrhages. These lesions were frequently combined. In three cases no lesions were found. The presence of these histological lesions was compared with those found in a group serving as controls, in whom no reddish-purple spots were seen at laparoscopy. Our study shows that there is a close statistical relationship (X2: 19.01; p less than 0.001) between the histological and laparoscopic changes. We conclude that: 1) Reddish-purple areas on the liver surface are caused by Peliosis hepatis or are Peliosis hepatis-related lesions, and 2) Peliosis hepatis is not an extremely rare condition in laparoscopy.
肝脏表面偶尔出现的红紫色区域与肝紫癜有关。本研究的目的是确定：1）在总共3035例腹腔镜检查中这些变化的发生率；2）这些腹腔镜检查变化的组织学基础。在20例（0.65%）病例中，在肝脏表面发现了圆形、三角形、星形或网状的红紫色斑块。取自这些区域的肝脏活检显示：1）肝血窦扩张；2）充满血液的腔隙；3）小叶内出血。这些病变常合并出现。有3例未发现病变。将这些组织学病变的情况与一组作为对照的病例进行比较，对照组在腹腔镜检查时未见到红紫色斑点。我们的研究表明，组织学变化与腹腔镜检查变化之间存在密切的统计学关系（X²：19.01；p＜0.001）。我们得出结论：1）肝脏表面的红紫色区域是由肝紫癜引起的，或是与肝紫癜相关的病变；2）在腹腔镜检查中，肝紫癜并非极为罕见的情况。
