title: Intrahepatic lithiasis above a bilio-digestive anastomosis.
abstract: The authors review their experience of twenty-five cases of intrahepatic lithiasis proximal to a bilio-digestive anastomotic stricture. Patients were operated on between 1970 and 1990, with a later follow-up in 1993. The pathogenesis of stone formation, in these cases, was relatable to multiple factors: biliary infection, presence of lithogenic nuclei (e.g. foreign bodies such as suture stitches), biliary stasis due to the stenosis. Management of this peculiar disease must take into account both surgical options and percutaneous as well as endoscopic methods. Our approach is the reconstruction of the stenotic anastomosis at its highest point, associated with intraoperative lithotomy followed by post-operative lithotomy and lithotripsy (if necessary) using PTCS (percutaneous transhepatic cholangioscopy). The best results are achieved with cooperation between surgeon, radiologist and endoscopist, aimed at preventing post-operative complications and severe consequences for the patient.
