Therap Adv Gastroenterol 2021 15;14:17562848211002023. Epub 2021 Apr 15.

Department of Gastroenterology & Hepatology, Erasmus MC, University Medical Center Rotterdam, Doctor Molewaterplein 40, Room Na-609, Rotterdam, 3015 GD, The Netherlands.

Patients with cholangiocarcinoma have poor survival since the majority of patients are diagnosed at a stage precluding surgical resection, due to locally irresectable tumors and/or metastases. Optimization of diagnostic strategies, with a principal role for tissue diagnosis, is essential to detect cancers at an earlier stage amenable to curative treatment. Current barriers for a tissue diagnosis include both insufficient tissue sampling and a difficult cyto- or histopathological assessment. Read More

Digital Cholangioscopy-guided Cold Snare Resection of an Inflammatory Intraductal Pseudopolyp.

Dig Endosc 2021 Apr 12. Epub 2021 Apr 12.

Department of Gastroenterology and Hepatology, University Hospitals Leuven, Belgium.

Digital single-operator cholangioscopy (DSOC) has revolutionized the endoscopic diagnosis and treatment of various hepato-pancreaticobiliary diseases, such as indeterminate biliary strictures and large balloon dilation-refractory common bile duct (CBD) stones, using either a retrograde or antegrade approach. Direct visualization provided by DSOC has furthermore paved the road towards minimally invasive treatment of intraductal neoplasms, although little evidence is available in this specific context. A 70-year-old patient was admitted following several episodes of colicky abdominal discomfort, mixed liver function abnormalities and non-intentional weight loss. Read More

Single-operator cholangioscopy-guided biopsy of indeterminate bile duct strictures - Work in progress.

Dig Endosc 2021 Apr 7. Epub 2021 Apr 7.

Digestive Health Institute, Orlando Health, Florida, USA.

Determining an accurate diagnosis in indeterminate biliary strictures is challenging with historically low sensitivity of 50-60% as all presently available diagnostic modalities possess some degree of inherent limitations. However, the development of the second-generation single-operator cholangioscopy system (SpyGlassDS, Boston Scientific Corp.) has resulted in a significant improvement in the diagnostic sensitivity to 75-85%, and we have recently shown in a randomized trial that an accurate diagnosis can be established in 90% of patients with indeterminate biliary strictures.
