title: Colon cancer presented with sigmoid volvulus: A case report.
abstract: BACKGROUND
  Sigmoid volvulus is the most prevalent type of colonic volvulus. Colon cancer is seen less where sigmoid volvulus is common, so it is rare to see that colon cancer is synchronous with sigmoid volvulus.
  
  
  METHODS
  We would like to present a case of sigmoid volvulus caused by colon cancer in a male patient aged 80 who was referred to the hospital with toxaemic shock presentation.
  
  
  CONCLUSIONS
  Sigmoid cancer can be presented as sigmoid volvulus to the emergency department. In intestinal obstruction early diagnosis is of crucial importance. Computarized tomography is a diagnosis tool that should be preferred both in the diagnosis of obstruction and in detecting its cause, localisation, degree and complications.
  
  
  CONCLUSIONS
  When surgery is performed due to the urgent colonic obstruction in colonic volvulus diagnosed patients, a colon tumour should be considered in the same column loops or in the distal colon. We believe that CT is the method that should be preferred in large-bowel obstruction suspected patients.
