Cholangiocellular Carcinoma (T2)

Conventional mother–baby cholangioscopy has never gained wide acceptance and is available only in a minority of referral centers as the technology is technically difficult and expensive. Direct cholangioscopy (without a mother technology) using standard ultraslim endoscopes for biliary access is a novel, fascinating approach that could overcome several limitations of conventional cholangioscopy: It is a 1-operator procedure, there is no need for a second light source and processor, it provides excellent high-resolution images, and devices are equipped with a 2.0-mm diameter that allows the insertion of larger biopsy forceps and the use of a variety of endoscopic retrograde cholangopancreatography accessories. A direct cholangioscopy is demonstrated in a 45-year-old male patient who was admitted for painless jaundice after laparoscopic cholecystectomy for acute acalculous cholecystitis 6 weeks ago.
