[Laparoscopy possible even in cholelithiasis. Results for 96 patients from three different hospitals are reviewed]

At laparoscopic cholecystectomy, a procedure routinely used at Swedish surgery departments today, common bile duct stones are found to be present in 5-10 per cent of cases. During recent years, several alternative procedures have been evolved for the management of duct stones, such as operative or postoperative endoscopic sphincterolomy, or conversion to open surgery and choledochotomy. The article gives an account of laparoscopic treatment of common bile duct stones, and results obtained in 96 patients from three surgery departments in Sweden. Three different primary techniques were used: saline flushing via the cholangiography catheter, after intravenous injection of 1 mg of glucagon (in six cases of small stones); transcystic common duct exploration (TCDE), with cholodochoscopy and a Dermia basket (68 cases); and laparoscopic choledochotomy and choledochoscopy (22 cases). The success rate was 88 per cent (84/96), and mortality zero. In many cases the postoperative course was similar to that of patients undergoing laparoscopic cholecystectomy alone. We recommend TCDE in cases of common bile duct stones of no more than 8-9 mm in diameter, and where the cystic duct is large. Single-stage laparoscopic treatment of bile duct stones seems to be a safe and effective method of dealing with two problems in the same setting, and is an important alternative in the management of duct stones.
