Summary. The anatomy of the pancreatic veins has become the object of renewed interest due to the advent of pancreatic phlebography coupled with selective blood sampling to diagnose the site of endocrine tumors of this organ.This study, based on the examination of 50 postmortem glands prepared by the technique of injection-corrosion, was undertaken to identify the veins of the pancreas and establish anatomicosurgical correlations.The right pancreas is drained by four relatively constant veins of unequal importance. The two superior pancreaticoduodenal veins (posterosuperior and anterosuperior) join with the portal vein and gastrocolic venous trunk. Due to their large drainage territory these veins are the main routes of cephalic pancreatic venous return. The inferior pancreaticoduodenal veins (posteroinferior and anteroinferior) most often run into the jejunal veins and less frequently end in the superior mesenteric vein.A part of the right pancreas can be referred to as the retrovenous segment. Drainage of this territory is via the anteroinferior and both posterior pancreaticoduodenal veins as well as by one or two small veins (veins of the retrovenous pancreas) which merge with the posterior surface of the superior mesenteric vein.The left part of the pancreas is drained by numerous small venous tributaries of the vena lienalis. A second drainage axis, present in half of the cases studied, is the inferior pancreatic vein. The left gastric, inferior mesenteric and middle colic veins afford an accessory route of drainage of the left pancreas.The anatomical and surgical junction between the right and left parts of the pancreas can be referred to as the prevenous segment. The drainage of this segment is most often via the neighboring veins, although in some cases may be via true isthmic veins, which join the anterior surface of the mesentericoportal trunk.A protocol for the phlebographic exploration of the pancreas is proposed, based on these anatomical findings. Taking multiple selective samples of venous blood for hormone determinations should allow reduction of the error of tumor localization related to the rich network of venous anastomoses in the pancreas.

Un rapprochement des deux extr6mit6s osseuses est souhaitable lorsque l'on a fait une simple symphysiotomie. Turner-Warwick (1972) en cas de r6section osseuse, comble la zone de r6section par un lambeau 6piploique, ce qui n'6vite pas cependant la possibilit6 d'une 6ventration, voire d'une hernie v6sicale [20]. I1 semble par contre que cette ouverture du cadre osseux ne provoque aucune g~ne ~t la marche.
