The utility of intraoperative cholangiography with acute cholecystitis

An increasingly important subset of patients with biliary tract disease are those with acute cholecystitis. The indications for both routine or selective intraoperative cholangiography (IOC) during elective cholecystectomy may not be appropriate for this group. The utility of IOC in the presence of acute cholecystitis was examined. The medical records of 223 patients with histologically confirmed acute cholecystitis were reviewed. Clinical and laboratory criteria included age, sex, white blood cell count (WBC), serum bilirubin and alkaline phosphatase levels. In 52 (23%) patients, IOC was not attempted and was technically unsuccessful in 15 (7%) patients. IOC was successful in 156 (70%) patients and, of these, six (4%) had a false-positive examination. The remainder are divided into two groups. Group 1 (131 patients) had true-negative IOC, whereas Group 2 (19 patients) had true-positive IOC as evidenced by stone recovery upon surgical exploration. When comparing Group 2 with Group 1, the mean preoperative laboratory values are higher; these differences do not reach statistical significance. Further, within Group 2, five (26%) patients did not demonstrate any clinical or laboratory elevations suggestive of common duct pathology. Thus, in acute cholecystitis, laboratory criteria do not appear to discriminate between the presence or absence of choledocholithiasis. IOC is advocated as an integral component of the operative procedure.
