“…It is now accepted that the SpyBite® forceps has the ability to gather material for histological analysis in most situations, ranging from 82% to 97% [3,19]. The lower specificity in the earlier study (82%) was driven by biopsy results that were inadequate for a histologic interpretation on an intention to treat (ITT) analysis.…”

“…Cholangioscopy using the SpyGlass® with a SpyBite® forceps can potentially overcome this deficiency, allowing the evaluation of the mucosa and biopsies be obtained under direct visualization. Sensitivity of SpyBite® biopsy forceps is much greater for intrinsic (66%) than for extrinsic (8%) malignant lesions [19]. On the other hand, the sensitivity of SpyGlass® visual impression alone was less severely compromised by extrinsic (62%) than intrinsic (84%) lesions.…”

“…Overall, the diagnostic accuracy, sensitivity and specificity of POCS-guided biopsies has been shown to be 72%-85%, 49%-82%, and almost 100%, respectively. [92][93][94] POCS can increase the yield of ERCP in the assessment of the longitudinal extension of PCC and DCC. The prospective study of 43 patients with CC showed that POCS had accuracy of 82% and 92% for diagnosing longitudinal extension of CC on the hepatic side (to the second order bile ducts) and papillary side (intrapancreatic common bile duct) respectively.…”

“…In this sense, periampullary forceps biopsy (and cytology) should be added in cases with biliary stricture, as this method has high sensitivity for confirming cancer tissue in the biliary cancer cases (77% [69,70] -92% [71] ).…”
