Percutaneous biliary drainage: technical and catheter-related problems in 200 procedures

Percutaneous management of malignant biliary disease: factors that influence ability to overcome the stricture.

“…Mueller et al (11) reported that decreased duct caliber above the obstruction to straighten the course of the guide wire directing into the lumen, resolution of reactive edema at the site of the obstruction and development of a transparenchymal tract around the catheter enabling the use of large-caliber catheters are a few factors that might account for easier catheterization of a stricture in a delayed second session. For this reason, we chose two sessions as the cut-off value in our study.…”

“…Failure to traverse biliary strictures has been found to be unrelated to the stricture type or location in previous studies (9,10). Mueller et al reported that the likelihood of successful stricture recanalization could not be predicted based on the initial cholangiographic appearance (11).…”

A New Exchangeable Long Biliary Endoprosthesis for Percutaneous Transhepatic Internal Drainage

“…Complications requiring catheter change include dislodgement, endoprosthesis obstruction due to sludging or tumor growth, acute pancreatitis and erosion of the duodenal mucosa", [11][12][13][14]• Several innovative methods for endoprosthesis removal have been reported', 2,16-18). However, these are not always successful, and some patients have required an external drainage catheter placed parallel to the nonfunctional endoprosthesis.…”
