title: Percutaneous removal of biliary stones.
abstract: Since 1983 we have performed percutaneous treatment of biliary lithiasis in 97 patients. Previous retrograde endoscopic procedures were incomplete or infeasible in all patients. Immediate results were excellent resulting in complete resolution of lithiasis in 89 of 97 patients (92%). In 4 patients (4%) partial success was obtained (symptoms subsided although there were nonobstructing residual stones). Percutaneous treatment failed in 1 patient (1%). Three patients died. Complications occurred in 14 of 97 patients (14%) and mortality at 30 days was 3%. Long-term results were evaluated in 71 patients who had a least a 6-month follow-up (mean 31 months and range 6-78 months). Eight of 71 patients (11%) had recurrence of stones and 7 of these were successfully retreated transhepatically. Percutaneous removal of biliary stones is efficacious because it has a high cure rate, a low complication rate, and a mortality rate that compares favorably to that of surgery even though the patients are usually older and in poorer general condition.
