title: [Jejunal intussusception with gastrointestinal bleeding caused by metastatic lung cancer].
abstract: Intestinal intussusception caused by metastatic tumor is uncommon. Symptomatic small bowel metastases from lung cancer have been rarely reported. Here we report a case of intussusception with gastrointestinal bleeding induced by jejunal metastasis of non-small cell lung cancer with a review of the literature. A 52-year-old man was admitted to our hospital because of melena. He had underwent right pneumonectomy and received systemic chemotherapy with radiotherapy for squamous cell lung cancer. Esophagogastroduodenoscopy and colonoscopy failed to reveal bleeding focus. Abdominal CT scan revealed jejunal intussusception and histologic examination of resected jejunum showed metastatic mass from lung cancer. In patients with small bowel obstruction and history of malignancies, possibility of small bowel metastatic tumor should be considered.
