Percutaneous cholecystolithotomy with endoscopically directed lithotripsy
with a pulsed-dye laser was performed in eight patients for the treatment
of symptomatic gallstones. All patients had stones that were not amenable
to therapy by less invasive techniques. During the first stage of a
two-stage procedure, a cholecystostomy catheter was placed percutaneously.
During the second stage, performed at least 10 days later, the stones were
fragmented with a laser and removed. Fragmentation of the stones was
successful in all patients. In six patients, the gallbladder was completely
cleared of stones, as assessed with endoscopy and cholecystography. In two
patients, residual fragments remained in the gallbladder. No laser-related
complications occurred. This preliminary experience suggests that the
pulsed-dye laser is safe and effective in endoscopically directed
lithotripsy of gallbladder stones.
