Laparoscopic cholecystectomy and management of choledocholithiasis.
The advent of laparoscopic cholecystectomy (LC) has led to a reassessment of the approach to the management of choledocholithiasis. In a consecutive series of 418 patients undergoing LC, common bile duct (CBD) stones were suspected pre-operatively in 130 patients. Forty-five of the patients (35%) were found to have CBD stones on either pre-operative endoscopic retrograde cholangiopancreatography (ERCP; 20) or on operative cholangiography (OC; 25). Common bile duct stones were detected on OC in a further 12 of 288 patients (4.2%) without pre-operative suspicion of choledocholithiasis. Of the total of 57 patients with CBD stones, the duct was cleared by pre-operative ERCP and endoscopic sphincterotomy (ES) in 15 patients. In 13 patients, two of whom had had a pre-operative ERCP and ES, duct clearance was achieved by relaxing the sphincter pharmacologically and flushing the CBD via the OC catheter. One patient had an on-table ERCP and ES with successful stone extraction during LC. Eleven patients were converted to open operation with bile duct exploration. Sixteen patients had a postoperative ERCP. In five patients the CBD stones had passed spontaneously in the time between LC and ERCP. Ten patients required ES to clear the duct of stones. One patient had a failed ERCP and is still awaiting a repeat. The remaining patient was scheduled, but did not return for follow-up ERCP. In summary, pre-operative ERCP was indicated in less than 10% of patients in this series.(ABSTRACT TRUNCATED AT 250 WORDS)
