Usefulness of convex type EUS for suspected case with transient cholangitis by choledocholith

Abstract

Purpose: To consider how we can avoid unnecessary ERCP by incorporate a convex EUS in a diagnosis system for the case that transient cholangitis with the choledocholith is suspected.

Method: Reviewed 48 cases which were diagnosed as transient acute cholangitis after convex type EUS observation had been introduced in our hospital, we assessed a choledocholith rate of detection by convex type EUS.

Result: We had made an observation by EUS for all cases which were diagnosis of transient cholangitis and confirmed choledocholith in 10 cases (20.8%). After that we performed ERCP and succeeded choledocholith removal for all 10 cases.

Conclusion: As the result of EUS observation, we could detect the small choledocholith which hardly point out by the other examination and could figure out which are ERCP required cases.
