This study is a retrospective review of 258 procedures on the gallblad
der and bile ducts (115 without and 143 with flexible choledochoscope)
. There were 14 bile duct explorations for stone removal without chole
dochoscopy and 16 with a flexible choledochoscope. Residual stones wer
e found in 2/14 (14.2%) cases without and 1/16 (6.3%) case with choled
ochoscope. A rewiev of the literature confirms that there are fewer re
sidual bile duct stones following flexible choledochoscopy. There were
no complications attribuable to the procedure.
