Abstract
A 77-year-old man developing ileus several times and treated elsewhere since November 2006 was admitted in February 2007. Abdominal computed tomography showed intussusception of the small intestine and endoscopic examination showed a tumor in jejunum. Based on a diagnosis of a tumor of the small intestine, we conducted laparoscopy-assisted partial jejunal resection. Histopathological findings showed poorly differentiated leiomyosarcoma. Six months after the first operation, the man was admitted because for abdominal pain and found in computed tomography to have a tumor 10 cm in diameter in the abdomen, which we diagnosed as mesenteric hematoma. Because we found that the tumor grew in computed tomography taken 4 days after, we conducted partial jejunal resection. Histopathological findings showed recurrence of leiomyosarcoma at the mesenterium.
