Perforation of Gastrointestinal Stromal Tumor in Small Bowel on an Elderly Patient Presenting Acute Abdominal Pain.

Acute abdominal pain as a common complaint in elderly patients may differ from that in younger patients. In elderly patients, the diagnostic accuracy of acute abdominal pain is lower compared to that in younger patients. On the other hand, the mortality in elderly patients with acute abdominal pain is far higher than that in the younger patients. Therefore, early and correct diagnosis of acute abdominal pain for the elderly patients could significantly influence the outcome. In this report, we describe a case of a 84-year-old man with a ruptured small bowel gastrointestinal stromal tumor who presented at the Emergency Department with acute abdominal pain. Laparotomy was performed because perforation of a tumor in the jejunum was found by computed tomography. Diagnosis was confirmed by histopathology and immunohistochemistry. Therefore, small bowel disease should be considered when exploring the cause of acute abdominal pain in elderly patients. [ABSTRACT FROM AUTHOR]
