Abstract
No comprehensive knowledge of duodenal tumours exists in the current literature; individual types of malignant tumours may be described within malignancies of the small bowel, sets of case reports, or individual cases. Ampullary carcinomas are the exception and they are detailed in the current WHO histological classification of tumours of digestive system.
Neither national nor international literature sources provide a comprehensive review of their therapy. The situation is similar when searching for surgical procedures.
Resection procedures on the duodenum should thus be performed in specialized centres with sufficient experience with hepato-pancreato-biliary surgery.
