  • Title: Duodenoscopy in the diagnosis of upper gastrointestinal disease.
    Author: Beaudin DJ, DaCosta LR, Prentice RS, Beck IT.
    Journal: Can Med Assoc J; 1973 Mar 03; 108(5):565-9. PubMed ID: 4689554.
    Abstract:
    Duodenoscopy was undertaken in 143 patients with upper gastrointestinal tract symptoms. There were no complications of the procedure. The duodenum was successfully entered in 98% of attempts, and in 90% of patients the examination was judged to be technically successful. When compared with radiological assessment, the findings at duodenoscopy significantly altered diagnosis and management in 21% of patients. The endoscopic appearance of the non-ulcerated duodenal mucosa could not be consistently correlated with changes found in biopsy tissue obtained under direct vision. Duodenoscopy is a valuable adjunct in the clinical assessment of upper gastrointestinal tract symptoms suspected to be due to pathological changes in the duodenum.
