Selective intraoperative cholangiography. A case for its use on an anatomic basis.
The routine use of intraoperative cholangiography has vastly improved the results of common duct exploration by reducing the number of negative explorations. The controversy surrounding the use of routine versus selective intraoperative cholangiography has centered on the incidence of unsuspected common-duct stones. A prospective study was designed to examine both preoperative clinical data and intraoperative anatomical information to determine criteria that would identify patients who would not require cholangiography. One hundred consecutive patients undergoing cholecystectomy were included in the study. When considering patients without preoperative clinical data suspicious for common duct stones three anatomical conditions were identified in which common duct stones would not be present: cystic duct less than 3 mm; smallest stone size greater than 6 mm; a single stone. Using intraoperative criteria as a basis for cholangiography, 44 per cent of patients without clinical suspicion of common duct stones would be spared an intraoperative cholangiogram. It is the authors' opinion that the addition of anatomic findings to preoperative clinical data can further reduce or eliminate the risk of unsuspected stones while sparing a large number of patients the risk and expense of routine intraoperative cholangiography and possible negative duct exploration.
