title: Surgical management of small bowel metastases from primary carcinoma of the lung.
abstract: OBJECTIVE
  To investigate the treatment and outcomes in a series of seven cases of small bowel metastases from lung cancer.
  
  
  METHODS
  A total of 4114 patients with lung cancer were referred to this institution from 1995 to 2005. Seven (0.17%) developed symptomatic small bowel metastasis and were treated surgically. The clinical, radiological, and pathological records were reviewed.
  
  
  RESULTS
  Small bowel metastases were diagnosed from 0 to 31 months (mean 11.5 months) after the diagnosis of lung cancer. The clinical symptoms at presentation were acute peritonitis in two patients and abdominal pain in five. Small bowel metastasis was suspected on abdominal X-ray in three cases, computed tomography in two, small bowel radiography in one, and endogastroduodenoscopy in one. All patients underwent surgery and there were no perioperative deaths. Intestinal resection was performed in five cases and a bypass in two. A small bowel metastasis was found in the ileum in four patients. The mean survival period was 7.7 months after surgery. One patient lived for 22 months after bowel resection. Oral intake was possible 1 month after surgery in six cases.
  
  
  CONCLUSIONS
  Surgical management should be considered as palliative treatment in patients with a bowel obstruction or peritonitis caused by primary lung cancer.
