Fracture of an expandable metallic stent placed for biliary obstruction due to common bile duct carcinoma.
We report our second case of fracture of a SMART self-expandable metallic stent (Cordis Endovascular, Warren, NJ) placed to treat biliary obstruction due to an unresectable common bile duct carcinoma. An 82-year-old man presented with jaundice. Computed tomography and ultrasonography on admission demonstrated a mass in the lower common bile duct. The mass was identified as a common bile duct obstruction. A SMART stent was inserted. Ten months after stent insertion, two additional SMART stents were inserted to relieve obstructive jaundice due to occlusion of the first stent. Fourteen months after insertion of the first stent, endoscopic examination revealed stenosis of the duodenum due to invasion of the common bile duct carcinoma, prompting us to perform a gastrojejunostomy 1 month later. Three months after gastrojejunostomy, the patient presented with obstructive jaundice and cholangitis. A fracture of one of the stents was then discovered on plain X-ray films and percutaneous transhepatic cholangiography. Two SMART stents were inserted simultaneously. In conclusion, we report the fracture of a SMART stent placed for common bile duct carcinoma. Fracture should be considered as a possible complication after metallic stent insertion.
