[Small bowel perforation and occlusion after migration of biliary and cystogastric prosthesis]. / Perforation et occlusion du grêle après migration de prothèse biliaire et de prothèse kystogastrique.

We report on two cases of intestinal complications associated with the migration of biliary and cystogastrostomy stents. In the first case, intestinal perforation occurred after migration of an Amsterdam type biliary stent. In the second case, a double pig tail endoprosthesis induced intestinal occlusion which was successfully managed without surgery. Complications after intestinal migration of biliopancreatic stents are very rare and usually involve the colon. Our observations point out the potential gravity of intestinal migration of biliopancreatic stents and, as in the second case, the possible resolution of stent related intestinal occlusion after medical management.
