[Neonatal obstruction associated with duodenal diaphragm: about a case].

Duodenal diaphragm is one of the rare types of duodenal atresia described, causing intestinal obstruction in the neonatal period. It is caused by embryological factors. We report the case of a 17-day-old newborn hospitalized and treated for duodenal obstruction at the University clinics in Lubumbashi and whose intraoperative finding was duodenal diaphragm. Evolution was good after surgery.
