Introduction:
ERCP has been a significant advance in the diagnosis and treatment of pancreatic and biliary diseases. However, anatomic variations may prevent successful ERCP.
Methods:
Advancement of a duodenoscope during ERCP was impeded in 4 patients by anatomic alterations of the esophagus and/or the stomach. The overtube, 80 cm length, was used to allow passage of a duodenoscope to the papilla.
Results:
All overtube assisted ERCP procedures were completed successfully and included sphincterotomy (2), bile duct stone extraction (2), and placement of a metal expandable stent (1).
Conclusion:
Use of an overtube allows safe and successful passage of a duodenoscope in patients with anatomic alterations of the esophagus and/or the stomach.
