Abstract

In the 40-month period from April, 1974 to July, 1977, postoperative choledochoscopy was performed 566 times in 186 patients at Teikyo University Hospital. Included in this series were 56 patients with retained common bile duct stones and 23 patients with intrahepatic stones; the stones were removed by postoperative choledochoscopy in 52 and 20 of these patients, respectively. In some patients, unsuspected stones were detected endoscopically after a completion T-tube cholangiogram was reported as negative for stones. Our experience to date indicates that this technique is of substantial diagnostic and therapeutic value in the management of biliary calculi. Therefore, routine use of postoperative choledochoscopy as an adjunct to T-tube cholangiography is strongly advocated. Failure of attempts to remove retained stones endoscopically and complications in this series were all attributable to inadequate insertion of the T-tube into the common bile duct at the time of operation. To overcome this problem, a T-tube of at least No. 18 Fr. caliber, and preferably of No. 20 Fr. caliber, should be inserted at operation into the common bile duct at a right angle, so as to avoid a tortuous sinus tract and produce a tract of sufficient caliber to permit postoperative choledochoscopy.

Résumé

En 40 mois, entre Avril 1974 et en Juillet 1977, 566 cholédocoscopies postopératoires ont été faites chez 186 malades à l'Hôpital de l'Université de Teikyo. Dans cette série sont compris 56 malades avec calculs résiduels du cholédoque et 23 avec calculs intrahépatiques. La cholédocoscopie a permis d'enlever les calculs dans 52 et 20 de ces cas. Dans certains cas, l'endoscopie a mis en évidence des calculs insoupçonnés, non révélés par la cholangiographie faite par le drain de Kehr. Notre expérience montre que cette technique est réellement utile pour le diagnostic et le traitement de la lithiase biliaire: nous conseillons donc son emploi, en combinaison avec la cholangiographie. Dans cette série, tous les échecs et complications de la méthode ont été dus à une malposition du drain de Kehr à l'opération. Pour éviter ces ennuis, il faut placer dans le cholédoque, à angle droit, un drain de Kehr calibre 18 Fr. ou même mieux 20 Fr., de façon à éviter les sinuosités de parcours et à obtenir un trajet suffisamment large pour permettre la cholédocoscopie postopératoire.
