    Notes: Abstract We report, in an adult, an asymptomatic association between cystic dilatation of the bile duct (type IV A in Todani’s classification) and anomalous pancreatico-biliary ductal union (APBD) with stones in a long common channel. In APBD, the connection between the common bile duct and the main pancreatic duct is located outside the duodenal wall and is therefore not under the influence of the sphincter of Boyden. An abnormally long common channel is in excess of 15 mm. Two types of convergence anomalies are defined according to whether the bile duct opens into the main pancreatic duct (BP) or the main pancreatic duct into the bile duct (PB). In APBD, there is probably a reverse pressure gradient between the bile and pancreatic ducts, with regurgitation of pancreatic juice into the bile duct, repeated attacks of cholangitis, stenosis and cystic dilatation. A long common channel is associated with a higher incidence of carcinoma of the gall bladder or the bile duct.

    Description / Table of Contents: Résumé Nous rapportons, chez l'adulte, une association asymptomatique d'un kyste cholédocien (type IV A de la classification de Todani) et d'une anomalie de la convergence bilio-pancréatique (APBD), avec présence de calculs dans un canal commun long. En présence d'APBD, la réunion entre la voie biliaire principale et le conduit pancréatique se fait en dehors de la paroi duodénale et échappe au contrôle du sphincter hépato-pancréatique. Un canal commun long est considéré comme pathologique s'il est 〉 15 mm. S'il apparît que le canal pancréatique vient se jeter dans la voie biliaire, cette anomalie correspond au type P-B. S'il s'agit du canal cholédocien qui vient se jeter dans la voie pancréatique, l'anomalie est de type B-P. Dans ces anomalies de la convergence bilio-pancréatique, il est probable qu'il existe une inversion du gradient de pression bilio-pancréatique avec reflux de liquide pancréatique dans les voies biliaires engendrant cholangite, sténose et dilatation kystique. Un canal commun bilio-pancréatique long est associé, avec une grande fréquence, un cancer de la vésicule ou des voies biliaires.

    Notes: Abstract The laboratory piglet is currently the preferred animal for experimental digestive surgery. In order to ensure optimal perioperative analgesic control with motor blockade during surgery together with rapid postoperative recovery, epidural anesthesia techniques were developed in this animal. We report the anatomo-radiologic studies (10 animals) and clinical experiments (51 transplantations of the liver and the small intestine) which led to the refinement of this anesthesia. In laboratory piglets, epidural anesthesia by distal transsacral (S4-S5) or sacrococcygeal approach is possible in a reproducible manner. The localization of the injection site is simple and epidural space catheterisation is easy without risk for the dural sac which ends at S1-S2.

    Description / Table of Contents: Résumé Le porcelet de laboratoire devient l'animal préféré en chirurgie digestive expérimentale. Dans le but d'assurer un contrôle analgésique périopératoire optimal avec un bloc moteur satisfaisant et la possibilité de réveiller rapidement l'animal à la fin de l'intervention, des techniques d'anesthésie épidurale ont été développées. Nous rapportons les études anatomo-radiologiques (10 animaux) et cliniques (51 transplantations de foie et d'intestin grêle) conduisant à la mise au point de cette anesthésie. Pour le porcelet de laboratoire, l'anesthésie épidurale par un abord trans-sacral distal (S4–S5) ou sacro-coccygien est possible de façon reproductible. La localisation du site d'injection est simple et le catéthérisme de l'espace épidural est aisé, sans risque pour le cul-de-sac dural qui se termine au niveau de S1–S2.

    Description / Table of Contents: The mass spectra of 2,6-dimethoxynaphthalene and 14 of its derivatives are reported. The fragmentation patterns proposed to account for the main peaks observed are frequently based on the presence of the appropriate metastable peaks. The fragmentation is initiated by the cleavage of an O—CH3 bond. The molecular ion is the most intense ion in each case and it does not appear to directly eliminate a methoxy group or a substituent directly attached to the naphthalene ring. With NO2 as a substituent the elimination of nitric oxide from the molecular ion has been observed and confirmed by peak matching.
    Notes: On rapporte les spectres de masse du diméthoxy-2,6 naphtaléne et de 14 de ses dérivés. La rationalisation du mode de decomposition par impact électronique qui est proposée, est confirmée la plupart du temps par des pics dûs aux transitions métastables appropriées. L'ion moléculaire, qui est le plus intense des ions dans chacun des spectres enregistrés ne semble pas subir d'élimination directe d'un group méthoxy ou de tout autre substituant directement relié au noyau naphtalénique. La dégradation semble plutot amorcée par l'élimination d'un radical méthyle à partir de l'ion moléculaire. Pour les dérivés nitrés, on a pu mettre en évidence la perte d'une molécule d'oxyde nitrique de l'ion moléculaire. Ce processus est confirmé par une mesure précise de masse du fragment résultant.
