This report deals with the "wandering" of foreign bodies and their cause. The rarity of such occurrences is emphasised. Two cases are presented, in the first patient a grenade splinter was removed from the common bile duct 33 years after injury; there are only seven instances in the literature of this condition. In the other case a mandrin was injected into an arm vein and travelled to the bifurcation of the abdominal aorta causing an aneurysm. According to the definition given by Schwaiger (1948) these 2 cases belong to the groups 2 and 3. In the case of the grenade splinter it is a secondary "wandering" from parenchymatous tissue to the biliary tract from where the splinter was able to descent the tract.
本报告探讨了异物的“游走”现象及其成因。文中强调了此类情况的罕见性。现介绍两例病例，第一例患者在受伤33年后从胆总管取出一枚手榴弹碎片；文献中仅有七例这种情况。另一例中，一枚橘子核被注入手臂静脉，随后游走至腹主动脉分叉处并导致动脉瘤。根据施韦格（1948年）给出的定义，这两例病例分别属于第2组和第3组。在手榴弹碎片的病例中，它是从实质组织继发“游走”至胆道，碎片由此得以沿胆道下行。
