Methyl tert-butyl-ether (MTBE) was sucessfully used for stone dissolution in 2 patients with multiple bile duct cholesterol stones. The presence of a biliary-enteric anastomosis precluded the endoccopic approach. Because of leakage of MTBE into the bowel, dissolution time ranged from 7.5 to 36 h. No significant complications other than mild nausea were encountered. No recurrence of stone formation has been found at a follow-up varying from 9 to 12 months.
