title: [Acute abdomen due to jejunal perforation secondary to metastatic lung carcinoma].
abstract: BACKGROUND
  Lung cancer metastases of small bowel are rare (1,1%), often with few or not symptoms. This aspecific onset and the difficult physical-instrumental approach to small bowel, led often to diagnosis at autopsy. This is not true for intestinal metastases that cause complications (haemorrhage, obstruction, perforation); in this cases emergency surgery leds to the diagnosis.
  
  
  METHODS
  We describe a case of a male 56 years old patient with acute abdomen due to perforation (X-ray and CT). He refers, about 6 months before, an upper right lobectomy for lung cancer, followed by adjuvant chemo-radiotherapy, because the presence of brain and bone metastases. During the emergency surgery we found out a perforation of the Treitz tract, treated with intestinal resection and immediate end-to-end anastomosis with manual suture. Histological examination shows the perforation of the intestinal wall tract with lung cancer metastases.
  
  
  CONCLUSIONS
  Our case shows that any acute abdomen in patient with lung cancer can be considered as expression of intestinal metastases. Negative prognosis of this complication imposes to surgeons only a local treatment.
