A Prospective Randomized Study Comparing Different Dilation Durations for Endoscopic Papillary Balloon Dilatation

Taiwan160 participantsStarted 2007-01

Plain-language summary

Endoscopic papillary balloon dilation is as effective as sphincterotomy in treating bile duct stone. However, a need to switch to sphincterotomy is noted in about 20% of cases receiving dilation for lithotripsy. It is hypothesized that a longer dilation duration (5 min. vs. 1 min.) can decrease the need of switching to sphincterotomy.
