Operative Cholangiography: An Aid in Reducing the Incidence of Residual Common Duct Stones

Abstract

The incidence of “unsuspected stones” in the common duct at the time of cholecystectomy is 3 to 4 per cent. The incidence of “overlooked stones” in the common duct after instrumental exploration is probably 8 to 27 per cent. Routine use of operative cholangiography will decrease the incidence of residual stones. No appreciable risk is associated with the procedure if reasonable care is exercised. Technically satisfactory results are obtained with mobile roentgenographs equipment.
