  • Title: Helicobacter pylori-induced lymphonodular hyperplasia: a new cause of gastric outlet obstruction.
    Author: Misra SP, Misra V, Dwivedi M, Singh PA.
    Journal: J Gastroenterol Hepatol; 1998 Dec; 13(12):1191-4. PubMed ID: 9918424.
    Abstract:
    A 30-year-old female was seen with symptoms and radiological evidence of gastric outlet obstruction. Endoscopic examination revealed findings suggestive of gastric outlet obstruction with nodularity of the antral mucosa leading to deformity of the pylorus. Endoscopic biopsies from the nodular antral mucosa showed presence of Helicobacter pylori-induced lymphonodular hyperplasia without evidence of mucosa-associated lymphoid tissue lymphoma. Anti-H. pylori therapy resulted in eradication of the H. pylori infection and the signs and symptoms of gastric outlet obstruction. The case demonstrates that H. pylori-induced lymphonodular hyperplasia can also cause gastric outlet obstruction. We believe this is the first such case to be reported.
