Majid A. Almadi et al. Using single-operator cholangioscopy for endoscopic evaluation of indeterminate biliary strictures: results from a large multinational registry
Single-operator cholangioscopy of indeterminate biliary strictures was investigated in this large multinational and prospective registry involving 289 patients, in the Asia, Middle East, and Africa (AMEA) regions. It was found to be useful in visualizing the stenosis and obtaining biopsies, with sensitivity and specificity based on biopsies of 75 % and 100 %, respectively.
