    Description / Table of Contents: Résumé Les auteurs ont analysé les rapports anatomiques de l'artère gastroduodénale (AGD) et de l'artère pancréatico-duodénale postérieure et supérieure (APDPS) avec le conduit cholédoque dans leur trajet rétroduodénal à partir de 35 blocs duodéno-pancréatiques sains et injectés après prélèvement. Les distances entre l'AGD, le pylore et le conduit cholédoque ont été mesurées dans le plan frontal. Les distances entre l'AGD et le conduit cholédoque ont également été mesurées dans le plan sagittal. L'origine et le trajet de l'APDPS par rapport au conduit cholédoque ont été étudiés. Les rapports de l'AGD et du conduit cholédoque ont été classés en 4 types : Type 1 (n=22) ces deux éléments s'éloignaient progressivement, l'artère se situant à gauche du conduit cholédoque; Type 2: (n=7) ils se rapprochaient sans se croiser; Type 3 : (n=5) l'AGD croisait le conduit cholédoque par en avant à la face dorsale de la partie supérieure du duodénum (D1) ; Type 4 : (n=1) l'AGD croisait le conduit cholédoque au dessus de D1 et cheminait le long de son bord droit. L'APDPS naissait à la face dorsale de D1 dans 20 % des cas (n=7) et croisait la face ventrale du conduit cholédoque à la face dorsale de D1. Dans 4 cas il n'existait pas d'interposition de tissu pancréatique entre l'APDPS et le conduit cholédoque. Il en résulte que le risque de plaie cholédocienne lors de l'hémostase d'un ulcère hémorragique de D1 par des points transfixiants est important lors d'un croisement des éléments artériels (AGD ou APDPS) et du conduit cholédoque. Ce risque est majoré en l'absence d'interposition de tissu pancréatique.
    Notes: Summary The anatomic relationships of the gastroduodenal artery (GDA) and the posterior superior pancreaticoduodenal artery (PSPD) with the bile duct in their retroduodenal courses were studied in 35 bloc specimens from normal cadavers, injected after removal. The distances between the GDA, the pylorus, and the bile duct were measured in the sagittal plane. The origin and course of the PSPD in relation to the bile duct were studied. The relation of the GDA and the bile duct were divisable into four types: in Type 1 (n=22) the two structures separated progressively, the artery being on the left of the bile ducts; in Type 2: (n=7) the structures approached each other without crossing, Type 3: (n=5) the GDA crossed in front of the bile duct at the level of the first part of the duodenum (D1), Type 4: (n=1) the GDA crossed the bile duct below D1 and ran along its right border. The PSPD originated at the posterior face of D1 in 20% of cases (n=7) and crossed the anterior surface of the bile duct at the posterior surface of D1. In four cases there was no pancreatic tissue between the PSPD and the bile ducs. It follows that the risk of injury to the bile duct when securing hemostasis by transfixing a bleeding duodenal ulcer in the D1 segment is great when the arterial structures (GDA and PSPD) cross the bile duct. This risk is increased when there is no pancreatic tissue between them.

    Description / Table of Contents: Résumé Les auteurs font une mise au point des bases anatomiques des rapports biliaires et artériels de la face postérieure du premier duodénum, à partir des données de la littérature classique et d'une étude portant sur 36 blocs duodéno-pancréatiques injectés. Ce travail essaie de mettre en évidence les variations topographiques et leur éventuel intérêt chirurgical.
    Notes: Summary The authors provide a summary of the anatomical relations between the bile duct and arteries in the region of the posterior surface of the first part of the duodenum, based on reports from the literature and from a study of 36 injected pancreaticoduodenal block specimens. An attempt is made to detail the topographical variations in these structures and to establish the surgical implications.
