Gastrointestinal Stromal Tumor Presenting with Acute Small Bowel Obstruction

Abstract

GIST or Gastrointestinal stromal tumors are rare connective tumors, Derived from Cajal cells or one of their precursors. And they are often located in the stomach or small intestine. Gastrointestinal stromal tumors (GISTs) are very rare neoplasms of the digestive tract, their clinical symptomatology is very variable according to the region affected or the size of the tumor, they could be responsible for abdominal mass, pain, or, digestive bleeding, as well as an alteration in the general state of health. And not very often, the diagnosis is made on the occasion of an intestinal occlusion. The GIST complicated by occlusion due either to invagination of the tumor mass in the small bowel or to exophytic development of the tumor. In CT scans, they are manifested by a localized parietal tumor thickening of variable size with most often an exophytic development, the diagnosis is based on molecular biology. The main treatment is radical surgery, but The Imatinib has revolutionize the prognosis of patients with unresectable and/or metastatic GIST. We report the case of a patient with a stromal tumor complicated by occlusion operated in our emergency department of visceral surgical in Ibn Rochd UHC.
