Spontaneous rupture of a small intestinal stromal tumor and causes acute abdomen: a case report

Abstract

Abstract Small intestinal stromal tumors (SIST) reports were not uncommon; however, spontaneous rupture of SIST resulting in the acute abdomen and requiring emergency surgery was uncommon. Here, we reported a case of SIST spontaneous rupture that caused an acute abdomen. The patient went to the Second Xiangya Hospital of Central South University due to abdominal pain for two days. According to his symptoms, signs, and imaging examinations, the preliminary diagnoses were "abdominal pain investigation cause" and "acute peritonitis.” Emergency laparotomy revealed an outgrowing 5-cm tumor in the ileum. The surface of the mass had ruptured, and blood clots and intestinal contents were flowing out. Postoperative pathological outcomes were considered high-risk SIST. In this paper, a literature review of this case was carried out to improve clinicians' understanding of SIST and reduce misdiagnosis and missed diagnoses.
