The discovery of retained common-bile-duct stones after operations on the gallbladder continues to be a frustrating experience for the general surgeon. Until recently this problem was solved in most patients by surgical re-exploration of the common bile duct. However, several alternatives to surgery are gradually gaining acceptance because of their lower morbidity and mortality. These methods are discussed with special emphasis on the use of a catheter with a steering mechanism and the Dormia basket (Burhenne's technique). This is the best alternative to surgery as it has no reported mortality, few complications and causes the least discomfort to the patient. It is highly successful and requires no hospitalization.
