RESUMEN

Objective To compare the diagnostic value of endoscopic ultrasonography (EUS) versus intraoperative cholangiography (IOC) for suspected common bile duct stones (CBDS).Methods 324 patients with suspected CBDS who were admitted to the Hepatobiliary Pancreatic Surgery Department of Shaoxing People's Hospital between June 2010 and June 2014 were retrospectively studied.Either EUS or IOC was used and the diagnostic value of these two imaging modalities was compared.Results The sensitivity, specificity, positive predictive value and negative predictive value of IOC in diagnosing suspected CBDS were 90.6%, 98.4%, 9.5% and 97.7% respectively.Its consistency rate was 96.9%.The sensitivity, specificity, positive predictive value and negative predictive value of EUS in diagnosing suspected CBDS were 97.1%, 100%, 100% and 99.1% respectively.Its consistency rate was 99.3%.Conclusions In diagnosing suspected CBDS, the sensitivity, specificity, positive predictive value and negative predictive value of EUS were significantly higher than IOC.When compared with IOC, EUS was more sensitive to detect occult CBDS and avoided unnecessary ERCP or bile duct exploration.Patients with negative EUS were less likely to have retained CBDS.

RESUMEN

Objective To discuss the value of intraoperative transnasal cholangiography in endoscopic sphincterotomy(EST) combined with laparoscopic cholecystectomy(LC) for treating cholelithiasis complicated with choledocholithiasis.Methods The EST was carried out to treat common bile duct stones and to conduct the endoscopic nasobiliary drainage(ENBD).During the LC the cholangiography was performed by way of ENBD.Results Intraoperative cholangiography was successfully completed in all 46 cases,with a cholangiography time of 5~15 min(mean,8.2 min).Secondary common duct stones migrated from the gallbladder were found by cholangiography in 4 cases,in 2 of which the stones were removed under endoscope during the procedure,and in 2 of which the stones were
