Ratanachuek T From 1997 to 1998 the first series of 21 patients with large biliary tract stones
(
1.5-4.0 em
with average 2.5 em in diameter) who underwent endoscopic stone extraction by using com-
bination of ERCP and EST with automatic stone-tissue detection pulse dye laser was carried out.
Male= 8, Female= 13, average age= 57.5 years (32-83) most of the stones were primary stones
(71.4o/c ). Laser fibers were controlled by balloon catheter with fluoroscope (blind technique) in
16
cases and by mother-babyscope system in
5
cases. The result in successful fragmentation of
stones was 87.5 per cent with the blind technique and 100 per cent with the mother-babyscope
technique. Temporary stents were used in the patients who had severe cholangitis and those who
required more than one session of lithotripsy (I 9% ). Complications consisted of controllable
cholangitis in 2 cases (9.5%) and there was no mortality. We conclude that stone-tissue detection
lithotripsy is very safe and effective in patients with large biliary tract stones and high surgical
risk especially
via
the direct mother-babyscope system.
