Perforated GIST of the small intestine as a rare cause of acute abdomen: Surgical treatment and adjuvant therapy. Case report.

A case of perforated gastrointestinal stromal tumor (GIST) of small intestine causing acute abdomen is described, with a brief review of the literature. A male patient presented with symptoms of acute abdomen. After evaluation, a laparotomy was performed, where perforation of a tumor in the ileum was found. The perforated part along with the tumor was resected and the cytopathological examination showed that the tumor was GIST. Postoperatively, the patient received treatment, using imatinib. Gastrointestinal stromal tumors are relatively rare and often present with vague symptoms. Their first clinical manifestation as acute abdomen due to their perforation is extremely rare. In emergency laparotomy, a R0 resection is required and adjuvant therapy with imatinib must be considered.
