Duodenitis

Duodenitis is a term given to inflammation of the duodenum.

Pathology

Etiology

A duodenitis can result from both intrinsic processes within the duodenum as well as from processes occuring outside the duodendum. It can occur from infective as well as non-infective inflammatory processes.

Non-infective inflammatory

• secondary involvement from
  • pancreatitis: considered most common
  • cholecystitis
• Crohn disease: duodenal involvement in 0.5-4% of cases
  • primary involvement: ulcer, stricture
  • secondary involvement: enteric fistula
• duodenal ulcers: occur most frequently in the duodenal bulb
• AIDS
• post radiation therapy

Infective

• Helicobacter pylori: considered the most common infectious cause
• giardiasis
• tropical sprue

Others

• NSAIDs
• alcohol
• diverticulitis
• gastric hypersecretion
  • ectopic gastrinoma (Zollinger-Ellison syndrome)

Radiographic features

Findings include thickening of folds (if present they are almost always found proximal to the ampulla of Vater), nodules or nodular folds, and erosions. Deformity of the duodenal bulb also may be seen.
