Abstract : The role of preoperative infusion cholangiography (PIC) before elective cholecystectomy has yet to be defined. Between 1985 and 1991 PIC was performed routinely in 694 patients with median (range) age of 52 (17-85) years with biliary calculus disease 1 or 4 days before elective cholecystectomy. Satisfactory opacification of the biliary system was achieved in 90.1 per cent and mild to moderate adverse reactions to the infusion of contrast medium occurred in 0.9 per cent of patients. Peroperative cholangiography (POC) in 43 of 499 patients with a normal PIC was normal. The presence of common bile duct stones was confirmed in 34 of 36 patients with prominent stones at bile duct exploration and in 8 of 26 with suspected stones at PIC. Bile duct dilatation (median diameter 10 mm) without concomitant stones was seen at PIC and confirmed at POC in 20 patients. Bile duct anomalies were found or suspected in 35 patients at PIC and were confirmed in six by POC (n = 5), or during the cholecystectomy making the anomaly incidence 0.9 per cent. Information provided by the PIC was not of crucial importance for safe execution of cholecystectomy in any patient, while a single (minor) bile duct lesion (1 of 694; 0.1 per cent) could be ascribed to severe pericholecystitis. The results of this study suggest that routine PIC is not warranted. However, PIC is an alternative to selective preoperative endoscopic retrograde cholangiography or selective POC. PIC needs to be supported by POC in approximately 20 per cent of patients (in case of absent or poor opacification of the bile ducts or suspicion of stones or anomalies at PIC).
