Introduction and case report

Achieving sustained biliary drainage in patients with cholestasis or cholangitis often represents a turning-point in the treatment of malignant and infectious diseases with hepatobiliary involvement. In this case — a 76-year-old woman with carcinoma of the pancreatic head, with hepatic metastases — endoscopic retrograde access was not possible, due to tumor tissue extending as far as the hepatic portal. Alternative procedures include percutaneous transhepatic cholangiography and drainage (PTCD) or endoscopic ultrasound–guided drainage techniques, with the advantages and disadvantages associated with each [1]. (For further information on this, reference may be made to the video contribution by B. Walter and A. Meining from Ulm in Endoscopy Campus [2]).

Transcutaneous bile drainage is possible after PTCD, but it is associated with a complication-prone loss of fluid and electrolytes and is susceptible to stent dislocation. For longer-term treatment, the aim must be to internalize the drainage from a transcutaneous to an intestinal route. This was not achieved in the present case even after the use of different catheters and various wires for guidance. In the following illustrations, we present an advanced technique with transcutaneous SpyGlass DS II–guided biliary drainage using a rendezvous technique, ending with successful placement of a metal stent. In this case, the procedure enabled the patient to undergo outpatient chemotherapy.

A special percutaneous version of the SpyGlass has recently been presented. In the present case, the regular SpyGlass DS II was used — with the advantage over conventional cholangioscopes that it only requires a small biliocutaneous tract diameter (12 versus 14–18 Fr).

It was not possible to pass a percutaneous wire under fluoroscopic guidance. Bougienage of the tract to 13 Fr initially was achieved in two sessions, and it was temporarily secured with a 12-Fr biliary drainage catheter (Cook).
