[Wandering of foreign bodies. (Grenate fragment in the common bile duct causing jaundice)].

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.
