| Abstract: | In 2,700 operations for biliary tract stones, intrahepatic lithiasis (stones located proximal to the confluence of the main hepatic ducts) was discovered in 36 patients (1.3 per cent). The diagnosis of intrahepatic lithiasis was determined only via intraoperative chalangiography in thirty-two cases (88.9 er cent); in 23 per cent of our cases of intrahepatic lithiasis, jaundice was never observed. This confirms that intraoperative cholangiography should be performed routinely in every case of biliary lithiasis. The removal of stones was generally performed by an indirect approach (papillostomy and/or choledochotomy). In 16.7 per cent of our cases, a direct approach was indicated. It is extremely important, after removal of calculi, to assure ample bilioenteric flow. Our surgical approach was therefore based mostly on the caliber of the biliary tract. When the tract was dilated less that 2 cm (in 20 cases), choledochohepaticotomy with papillostomy was most often performed (12 cases, 60 per cent). When the dilatation was more that 2 cm (12 cases), Roux-en-Y hepaticojejunostomy was performed in all. There was no operative mortality, although the long-term follow-up results were poor in 9.6 per cent of the cases. |
