    Description / Table of Contents: Résumé Afin d'évaluer la tolérance induite par la transplantation hépatique dans une greffe multi-viscérale, un modèle de transplantation associant foie et grêle a été élaboré chez le porc. Il s'agit d'animaux Large White Isogroupe O, typés dans le système d'histocompatibilité majeur “Swine Lymphocyte Antigen” (SLA) dont le poids varie de 30 à 40 kg. Afin de limiter la durée d'ischémie chaude, la dissection du greffon est réalisée sur l'animal donneur et doit tenir compte d'un certain nombre de caractéristiques anatomiques: -absence d'accolement intestinal au péritoine pariétal postérieur; -torsion antihoraire de 360° de l'intestin autour de l'artère mésentérique supérieure avec disposition droite des circonvolutions grêliques et gauche des spires coliques. Le pancréas bifide suit cet enroulement et sa résection doit respecter la vascularisation du grêle proximal; -l'artére hépatique nait d'un tronc commun avec une branche gastrosplénique de l'aorte entre les piliers du diaphragme et se dirige d'arrière en avant, sagittale, vers le pédicule hépatique qu'elle rejoint au bord supérieur du duodénum; -l'artère hépatique et ses branches sont dorsales par rapport à la veine porte; -la distribution artérielle hépatique suit une systématisation droitegauche et antéro-postérieure pour les six lobes hépatiques de cet animal quadrupéde.
    Notes: Summary In order to assess the tolerance induced by hepatic transplantation in a multivisceral graft, a model of a transplant combining the liver and small intestine was developed in the pig, using animals of Large White Isogroup O, typed in the system of major incompatibility as “Swine lymphocyte antigen” (SLA), whose weight varied from 30 to 40 kg. In order to limit the duration of warm ischemia, dissection of the graft was performed on the donor animal with respect for the following anatomic features: -absence of intestinal attachment to the posterior parietal peritoneum, -anti-clockwise torsion of 360° of the intestine around the superior mesenteric a. with the small intestine convolutions on the right and the colonic helix on the left. The bifid pancreas follows this rotation and its resection must respect the vascularisation of the proximal small intestine; -the hepatic a. arises from a common trunk with a gastrosplenic branch of the aorta between the crura of the diaphragm and travels sagittally from behind foward toward the liver pedicle, which it reaches ar the upper border of the duodenum; -the hepatic a. and its branches are dorsal in relation to the portal vein; -the hepatic arterial distribution follows a right-left and antero-posterior systematisation for the six hepatic lobes of this quadruped animal.

    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.
