A very thin camera passed through an endoscope up into the bile duct, so the doctor can look directly at a narrowing and take a targeted biopsy to find out whether it is cancer.
Boston Scientific's SpyGlass DS direct visualisation system was cleared on 16 January 2015 (K142922), followed by the SpyGlass DS and DS II system (K181439, 23 August 2018) and the SpyScope DS II catheter (K183636, 22 January 2019), under the choledochoscope code FBN; it is indicated "for use in diagnostic and therapeutic applications during endoscopic procedures in the pancreatico-biliary system including the hepatic ducts". A systematic review of 10 studies (456 patients) found pooled sensitivity of 60.1 per cent and specificity of 98.0 per cent for cholangioscopy-guided biopsy in malignant biliary strictures; in four studies of patients with previous negative imaging and brushings, sensitivity was 74.7 per cent and specificity 93.3 per cent.
A single-use steerable catheter with a digital camera, light and working channel is passed through a duodenoscope into the bile duct, giving direct images and a channel for biopsy forceps or lithotripsy probes.
