The functional lifetime for biliary endoprostheses has typically been 7 months. When combined with sphincterotomy for common bile duct stones, it affords an alternative to surgery in high risk patients.

The median time to onset of cholangitis appears to be approximately 16 wk and occurs mainly in patients with an in situ gallbladder or in cases of prosthesis insertion without sphincterotomy [9][10][11][12] .
