Combined laparoscopic and endoscopic treatment of gallstones and bile duct stones: a prospective study.

In patients with symptomatic gallstones the management of choledocholithiasis has been controversial since the introduction of laparoscopic cholecystectomy. A prospective study was made of 300 consecutive patients with symptomatic gallstones managed by laparoscopic cholecystectomy and preoperative endoscopic retrograde cholangiography (ERC) over 2 years. Fourteen patients were excluded either because urgent surgery was required or because they were unfit for laparoscopic cholecystectomy. ERC was performed on 96 patients (34 per cent) who were at risk of choledocholithiasis. The presence of bile duct calculi was confirmed in 59 patients (21 per cent of the total, 61 per cent of those undergoing ERC); stones were removed endoscopically in 53 cases (90 per cent of attempts). The remaining six patients underwent open cholecystectomy and bile duct exploration. Laparoscopic cholecystectomy was attempted in 280 patients (98 per cent); it was necessary to convert to open operation in only three (1 per cent). There were no deaths, no retained stones and no bile duct injuries, and only three patients (1 per cent) developed a significant postoperative complication. Symptomatic gallstones can be managed by preoperative ERC and laparoscopic cholecystectomy with minimal morbidity and mortality.
