LINTERET DE LILEO-COLOSCOPIE DANS LE BILAN DEXTENSION DU LYMPHOME GASTRIQUE

Gastric lymphomas are rare tumorsand accounts for only 3%. There are two groups of lymphomas: mucosa-associated lymphoid tissue (MALT) gastric lymphoma or diffuse large B-cell lymphoma. The management of this tumordepends on the histological grade and extension workup. It includes a clinical examination, radiological and endoscopic work-up including a total ileo-coloscopy in order to look for a synchronous intestinal localization.We report in this article the experience of our department concerning the interest of ileo-coloscopy in the assessment of gastric lymphoma extension. We included 87 patients followed for gastric lymphoma, 34 of whom underwent ileo-coloscopy preceded by thoracoabdomino-pelvic CT scan. Colonoscopy revealed an ulcerative colonic process in only 02 patients, whose CT scan also revealed a colonic thickening and the anatomopathological study was in favour of a colonic lymphoma.In the light of these results, is it not necessary to reconsider the interest of an invasive procedure in the work-up of gastric lymphoma with a normal abdominal scan?
