Duodenal Adenocarcinoma: 4 Cases Report

Duodenal adenocarcinoma being the most common tumor of the small intestine: 33 to 48%, it remains very rare representing only 0.5% of malignant tumors of the digestive tract. Our retrospective study focused on four cases during the period 2017-2022 with an average age of 53.25 years and a sex ratio of 1M/3F. The clinical signs were varied with a predominance of cholestatic jaundice and a deterioration in general condition. The diagnosis was confirmed thanks to the endoscopy and the anatomopathological study of the biopsies carried out in all our patients. All our patients benefited from a surgical treatment, curative or palliative, which consisted of three cephalic pancreaticoduodenectomy and in one case a gastro-jejunal anastomosis. The post-operative follow-up was simple in two patients, one of our patients presented with gastroparesis which progressed well under medical treatment. In addition, we deplore a death which presented a hemoperitoneum related to a hemostasis disorder.
