    Abstract:
    BACKGROUND: Intra-operative cholangiography has been shown to be a sensitive and specific method of demonstrating bile duct stones. This study investigated the feasibility, safety, and clinical value of selective trans-cystic intra-operative cholangiography in primary suture following three-port laparoscopic common bile duct exploration, and identified the factors that positively predict the presence of common bile duct stones. METHODS: From January 2008 to January 2011, 252 of 1013 patients undergoing laparoscopic cholecystectomy received selective trans-cystic intra-operative cholangiography and primary suture following three-port laparoscopic common bile duct exploration. Their clinical data were analyzed retrospectively. RESULTS: All operations were successful and none was converted to open surgery. The intra-operative cholangiography time was (8.3 ± 2.5) minutes, and the operative duration was (105.4 ± 23.1) minutes. According to selective intra-operative cholangiography, the positive predictive values of current jaundice, small gallstones (< 0.5 cm) and dilated cystic duct (> 0.3 cm), dilated common bile duct (> 0.8 cm), history of jaundice or gallstone pancreatitis, abnormal liver function test, and preoperative demonstration of suspected common bile duct stones on imaging were 87%, 25%, 42%, 15%, 32%, and 75% for common bile duct stones, respectively. Patients with several factors suggestive of common bile duct stones yielded higher numbers of positive cholangiograms. Unexpected stones were found in 13 patients (5.2%) by intra-operative cholangiography. The post-operative hospital stay was (4.7 ± 2.2) days. Post-operative bile leakage occurred in two cases, and these patients recovered by simple drainage for 3 - 7 days without re-operation. Of the 761 patients who underwent laparoscopic cholecystectomy alone, 5 (0.7%) presented with a retained common bile duct stone requiring intervention. The median follow-up was 12 months, and only one patient who once suffered from bile leakage presented with obstructive jaundice due to bile duct stenosis 6 months postoperatively. The other patients recovered without any serious complications. CONCLUSIONS: Selective intra-operative cholangiography yields acceptably high positive results. It is a safe, effective, and minimally invasive approach in patients with suspected choledocholithiasis and primary suture following three-port laparoscopic common bile duct exploration.
