title: [Primary adenocarcinoma of the jejunum. Diagnostic challenge by a rare tumour].
abstract: METHODS
  A 75 year old patient presented for many years with nausea and vomiting. The exacerbation of clinical presentation caused further investigation of the small bowel.
  
  
  METHODS
  The source of nausea and vomiting had been achieved by double contrast enteroclysis in the upper jejunum and it was confirmed with a coloskop.
  
  
  METHODS
  Histological result was a primary small bowel adenocarcinoma. The primary definitive therapy was a radical resection of the jejunal neoplastic loop, also as an important prognostic factor. Because of the tumour stadium adjuvant chemotherapy was not necessary.
  
  
  CONCLUSIONS
  Tumours of small bowel are always a diagnostic challenge. With the help of an primary small bowel adenocarcinoma we suggest an algorithm of diagnostic possibilities adjusted to the clinical situation.
