[Retention jaundice caused by central hepatic hepatoma. Treatment with Kron's extra-anatomic biliary prosthesis].

A 31 year-old patient presented with a retention jaundice from a centrally located hepatoma invading the hilum. Because of the patient's age and the severity of the pruritus and jaundice, palliative treatment was performed by percutaneous catheterization of the intrahepatic biliary tracts to drain the right and left hepatic canals. As the hilar stenosis could not be overcome, the external drainage was transformed into internal drainage by implantation of a Kron's biliary prosthesis linking the intrahepatic biliary tracts, following segment III hepatotomy, to the duodenal lumen, with burying of the prosthesis in the gastric antrum region. Jaundice was reduced until death of the patients from metastases 6 months later. This case demonstrates that the use of Kron's biliary prosthesis to perform a biliodigestive shunt from intrahepatic biliary pathways is a valid palliative procedure in patients with limited life expectancies.

Aminopyrine breath test: development of a 13C-breath test for quantitative assessment of liver function in humans.

BACKGROUND/AIM: 14C-aminopyrine breath test (ABT) has been shown to be well correlated to the severity of liver diseases, but its use is limited in countries where radioactive isotopes are severely controlled. The goal of this study was to develop a 13C-ABT based on a highly sensitive method to measure 13CO2 in breath samples. MATERIALS AND METHODS: The relevant parameters were studied in 26 controls and 27 patients: the 13CO2 enrichment of expired breath between t-10 and t+60 minutes was determined as the most simple and clinically useful parameter. The 13C-ABT was then prospectively compared to clinico-biological data and the galactose elimination capacity (GEC) in 82 patients. RESULTS: The 13C-ABT was well correlated to: i) the Child-Pugh classification; ii) GEC results; iii) the hepatic volume. The presence of ascites or alcoholic consumption did not alter significantly the results of the test. 13C-ABT appeared more sensitive than GEC to evaluate minor liver dysfunctions. CONCLUSIONS: The 13C-ABT is a simple and sensitive test to measure liver function. The use of the stable isotope 13C ensures the harmlessness of the test and the possibility to repeat it in a given patient.
