This is a comparative study of two types of choledochoscopes: The Wolf rigid scope and the flexible CHF B3 Olympus scope. These were used for the exploration of 120 consecutive cases of common bile duct disease covering a 4-year period. The rigid and the flexible choledochoscopes were used in 30 and 88 cases, respectively, while in another 2 cases both scopes were used to complete the examination. We established that the Wolf scope does not provide ease of handling in inexperienced hands. Its low price and durability under rough handling should not be an excuse for recommending it for beginners. On the other hand, the Olympus scope is an expensive and delicate instrument, which is much easier to handle. Both choledochoscopes can, however, equally provide good results in experienced hands.
