Abstract
INTRODUCTION: 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. PRESENTATION OF CASE: 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. DISCUSSION: 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. CONCLUSION: 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.

How this classification was reachedexpand
Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
