Single-operator cholangioscopy: more good numbers, with a few caveats.

: Referring to Almadi M et al. p. 574-582 The yield of ERCP techniques for detecting malignancy remains low; in a recent meta-analysis, the pooled sensitivities of brush cytology and forceps biopsy were 45 % and 48.1 %, respectively. Cholangioscopy biopsies improve detection of cholangiocarcinoma when combined with cytology and FISH, but not in patients with PSC. [Extracted from the article]
