La perforation des diverticules duodénaux juxta-papillaires, spontanée ou post-traumatique, est une affection grave. Elle est caractérisée par la difficulté d'établir le diagnostic qui repose essentiellement sur la tomodensitométrie. Le traitement consiste en une diverticulectomie, qui n'est pas sans risque, associée éventuellement à une dérivation bilio-digestive ou à un drainage duodénal. Nous rapportons deux observations de perforations de diverticules duodénaux juxta-papillaires, l'une spontanée, l'autre post-traumatique.

Perforation of juxta-ampullary duodenal diverticula, occurring spontaneously or after abdominal trauma, is a severe condition. Diagnosis is difficult to establish and is based on tomodensitometry, which is the most reliable diagnostic tool. Treatment consists in diverticulectomy that can be associated with drainage of the duodenum or anastomosis between digestive and biliary tract. We report two cases of perforated juxta-ampullary duodenal diverticula. Perforation was spontaneous in one case and complicated a blunt abdominal trauma in the other case.
