Spontaneous expulsion of a migrating infantry missile impacted in the duodenum and the common bile duct, 32 years after wounding.

32 years after the injury, an infantry bullet was found to extrude into the duodenum, with its sharp end impacted in the common bile duct. After several previous endoscopic examinations (duodenoscopy, ERCP), endoscopic removal was planned. In the meantime, the bullet was expelled per vias naturales, leaving a biliodigestive fistula.
