Nodular duodenum, a type of duodenal inflammation, showed symptom improvement with acid-reducing medications like ranitidine and omeprazole. However, these treatments did not significantly alter the underlying duodenal histology.

Area of Science:

  • Gastroenterology
  • Endoscopy
  • Histopathology

Background:

  • Nodular duodenum, or nodular duodenitis, presents as multiple erythematous nodules in the proximal duodenum.
  • It may represent a variant of duodenal inflammation, often associated with epigastric pain and other gastrointestinal symptoms.

Purpose of the Study:

  • To investigate the incidence, clinical presentation, histologic features, natural history, and therapeutic response of nodular duodenum.
  • To evaluate the efficacy of antisecretory therapy in managing nodular duodenum symptoms and endoscopic appearance.

Main Methods:

  • Retrospective and prospective study of 83 patients with nodular duodenum.
  • Endoscopic evaluation including biopsies for histology.
  • Prospective treatment with H2-antagonist ranitidine followed by omeprazole for refractory cases.

Main Results:

  • Chronic inflammation was the most common histologic finding (58%) in duodenal nodules.
  • H2-antagonist ranitidine significantly improved symptoms and endoscopic appearance (p < 0.05).
  • Omeprazole also showed significant improvement in symptoms and endoscopic findings for patients refractory to H2-antagonists (p < 0.05).

Conclusions:

  • Nodular duodenum is an endoscopically distinct entity.
  • Antisecretory therapy can clinically improve nodular duodenum but does not significantly alter underlying histology.
  • Nodular duodenum remains challenging to eradicate completely despite symptomatic improvement.
