    Notes: Abstract In the present work we recount our experience in handling common bile duct stones (CBDS) in our first 100 cases of laparoscopic cholecystectomy. In the first 50 cases our diagnostic procedures involved the use of ultrasound exploration and intravenous cholangiotomography 48 h before laparoscopic surgery. We found three cases of residual CBDS. One of the cases was treated by means of ERCP. The other two cases were resolved by carrying out a transparietohepatic cholangiography after the ERCP procedure failed. After this experience, we changed our strategy, introducing the intraoperative cholangiography in the cases with an unclear diagnosis. With this new approach, no residual CBDS occurred in the following 50 cases. These findings demonstrate the following: (1) In our hands, intravenous cholangiography is not more effective than ultrasound exploration in resolving dubious cases. (2) These dubious cases are more effectively diagnosed by means of selective intraoperative cholangiography. (3) When CBDS is treated by transparietohepatic cholangiography it proves to be less uncomfortable for the patient than ERCP and, as we found, even more efficient in removing the stones, although our experience is based on only two cases.

    Description / Table of Contents: Zusammenfassung Die Gallensalze setzen den enterohepatischen Kreislauf fort. Die Cholsäure (Carboxylic14C), nach ihrer intravenösen Injektion verteilt sich im Niveau des Portalkreislaufes, Dünndarmwand, Inhalt des Dünndarms, Leber und Stuhl, welches als gutes Zeichen der Absorbierungskapazität der Epithelzellen des Darms betrachtet werden kann. In Ratten, bei denen eine totale Dünndarmresektion (60–80 cm) durchgeführt wurde, beobachtete man nach 7 Tagen eine bedeutende Verminderung der Absorbierung der Cholsäure. Trotzdem ist 30 Tage nach der Operation das Gewicht der Tiere sowie die radioaktiven Befunde gleich den Tieren der Kontrollgruppe, und zwar im Blut der Portalvene und der V. Cava, sowie im Darminhalt, Leber und Stuhl. In dieser Studie wurde eine Erhöhung der Absorbierungskapazität der Epithelzellen des Dünndarms beobachtet.
    Notes: Summary Bile salts undergo an enterohepatic circulation. The relative distribution of labelled cholic acid in portal blood, enterocytes, intestinal contents and feces, following intravenous injection of (carboxylic-14C) cholic acid, can be considered as an indication of the absorptive capacity of the epithelium cells. Seven days after a massive small intestinal resection (60–80 cm), the animal weight and the bile salt absorption were significantly decreased. Nevertheless, thirty days after the operation, weight and radioactivities reached the values found in the controls: in portal and cava blood, liver, intestinal contents and feces. An increase of the absorptive capacity of the intestinal epithelial cells was also observed.
