Fractured guidewire fragments in the bile duct need to be removed because they may lead to infected liver hematoma or cholangitis [1] [2] [3] [4]. We report the successful endoscopic removal of a fractured guidewire fragment on the peripheral side of a malignant biliary obstruction using a biliary balloon dilation catheter.

A 73-year-old woman underwent detailed tests for obstructive jaundice. Contrast-enhanced computed tomography showed a mass lesion in the hilar bile duct ([Fig. 1 a]). Endoscopic retrograde cholangiopancreatography was then performed. Cholangiography showed a stricture in the hilar bile duct ([Fig. 1 b]). We then performed peroral cholangioscopy (POCS) (SpyGlass DS; Boston Scientific, Marlborough, Massachusetts, USA) for accurate diagnosis ([Video 1]). An irregular papillary protrusion, which was the suspected malignancy, was confirmed by POCS ([Fig. 2]). A guidewire (0.025-inch diameter, 450-cm length, angled tip; VisiGlide 2; Olympus, Tokyo, Japan) was negotiated to the posterior right intrahepatic bile duct using POCS. As the guidewire was being withdrawn, it fractured. The fractured fragment was located on the peripheral side of the malignant biliary obstruction ([Fig. 3]). The narrowness of the POCS channel (1.2 mm) may have caused friction and ultimate fracturing of the guidewire. Another guidewire was placed over the guidewire fragment, and a biliary balloon dilation catheter (MaxForce; Boston Scientific) ([Fig. 4]) was then inserted. It was inflated to the diameter of the bile duct, allowing it to adhere to the guidewire fragment, and carefully pulled until the fragment was on the papilla side of the malignant biliary obstruction. Finally, the fragment was removed using forceps under direct view of POCS ([Fig. 5]).

Although endoscopic removal of a fractured guidewire fragment has been reported [3] [5], removal from the peripheral side of the malignant biliary obstruction is thought to be difficult and has not previously been demonstrated. The shape of this balloon catheter was useful in allowing it to adhere to the guidewire fragment.
