In a series of 555 gastric polyps characteristic Elster's polyps were identified in 31 cases. Spiral bacteria (Helicobacter pylori) in these polyps were sporadic, much less frequent (9.7%) than in hyperplastic polyps (35%) in the present series and in relation to the bacteria frequency found in our randomly chosen gastric biopsy specimens (43%). The present results indicate that Elster's polyps are not readily colonized by Helicobacter pylori and accordingly, they do not show the signs of active gastritis. The reasons for this are unknown. One of the mechanisms preventing from bacterial colonization may be a different from normal gastric mucosa and other polyps character of mucus produced by glandular neck cells, which was found in our series of gastric fundic gland polyps.
在一系列555例胃息肉中，31例发现了具有特征性的埃尔斯特息肉。这些息肉中的螺旋菌（幽门螺杆菌）呈散在分布，其发生率（9.7%）远低于本系列中增生性息肉的发生率（35%），也低于我们随机选取的胃活检标本中发现的细菌发生率（43%）。目前的结果表明，埃尔斯特息肉不易被幽门螺杆菌定植，因此，它们没有活动性胃炎的迹象。其原因尚不清楚。在我们的胃底腺息肉系列研究中发现，阻止细菌定植的机制之一可能是腺颈部细胞产生的黏液性质与正常胃黏膜及其他息肉不同。
