Malignancy
NO
A newly developed peroral cholangioscopy (POCS) system, SpyGlass DS (Boston Scientific Co.) has high maneuverability, whereas its image quality appears relatively low in comparison with that of a traditional cholangioscope, CHF-B260 (Olympus Co.). This study aimed to evaluate acceptability of the accuracy of SpyGlass DS accompanied by simultaneous POCS-guided biopsy compared with that of CHF-B260 after fluoroscopy-guided biopsy to diagnose the lateral extent of extrahepatic cholangiocarcinoma (LEC).
Efficacy
The main outcome measure was the accuracy of overall preoperative diagnosis (OPD) of LEC which was defined based on all examinations, including POCS, and was evaluated with reference to the resected specimen.

Male and Female
Patients who underwent surgical resection after preoperative examinations to diagnose LEC were evaluated
(1) those in whom the clinical record on findings of the POCS examination could not be obtained or was insufficient for evaluation, (2) those who did not undergo surgical resection after examinations, and (3) those in whom the resected specimen was inappropriate to precisely evaluate the lateral extent.

All data on patients who underwent surgical resection for extrahepatic bile duct cancer after preoperative examinations, including POCS, to diagnose the lateral extent of extrahepatic cholangiocarcinoma at Sendai City Medical Center were extracted from a prospectively maintained database of endoscopic retrograde cholangiopancreatography.
