title: Severe stricturing Crohn's disease of the duodenum: A case report and review of surgical options.
abstract: BACKGROUND
  Duodenal Crohn's disease is a rare clinical entity that occurs in 0.5-4.0% of patients with Crohn's disease. A unique case of Crohn's disease of the upper gastrointestinal tract characterized by multiple strictures within the duodenum and jejunum is described in our review.
  
  
  METHODS
  A 41-year-old male presented with a 2-month history of intermittent, crampy abdominal pain accompanied by nausea, bilious emesis, early satiety, anorexia and weight loss. Physical examination revealed fullness in the epigastric region. Imaging demonstrated strictures in the proximal and distal duodenum with dilatation of the intervening segments. There was also gross dilatation of the proximal jejunum, which was followed by a 9cm strictured segment. There was no evidence of acute Crohn's disease. Although a Whipple's resection was initially considered as a form of operative intervention given the extent of disease within the duodenum, the discovery of unexpected disease intra-operatively presented a surgical dilemma. In this case, strictureplasty, surgical resection and bypass were used to treat the patient.
  
  
  CONCLUSIONS
  Diffuse stricturing of the proximal gastrointestinal tract is a rare manifestation of Crohn's disease. Although imaging can aid in surgical planning, intra-operative decision-making to deal with unexpected findings will remain an important aspect of the management of this entity.
  
  
  CONCLUSIONS
  The fundamental goal of the surgical management of strictures secondary to Crohn's disease is to relieve obstruction while maximizing bowel conservation. A variety of operative techniques are currently described for the management of duodenal Crohn's disease and are reviewed in this case report.
