Core Tip
Core tip: A new mother-baby system, consisting of a peroral baby cholangioscope and a maternal duodenoscope, was investigated in patients regarding its feasibility. Using the criteria “circular stenosis” and “irregular surface or margins”, peroral cholangioscopy (POCS) correctly described 27 out of 28 malignant biliary strictures and 25 out of 27 benign lesions (sensitivity, 96.4%; specificity, 92.6%, diagnostic accuracy 94.5%). The new 95 cm POCS allows for accurate discrimination of strictures and fixed filling defects in the biliary tract, provides improved sensitivity of endoscopically guided biopsies and permits therapeutic approaches for difficult intrahepatic stones.
