[Endoscopic diagnosis of duodenal and jejunal diseases].

We presented and studied the endoscopic diagnosis of the duodenal ulcer, duodenal tumors and duodenal bleeding. Duodenal Ulcer is classified according as location, form and evolutive stage. Duodenal tumors are divided in polyps, primitive tumors, pancreas anomaly and lymphoma. Duodenal bleeding can be diagnosed according its cause (inflammatory, tumors vascular and traumatic). It is emphasized the importance of the indications and methods of the enteroscopy. We show our experience in 313 duodenal ulcers cases and 98 enteroscopic diagnosis.
