Hyperplastic duodenal polyp

Last edited: 4/16/2026

Overview

Hyperplastic duodenal polyps are rare lesions composed of ectopic gastric mucosa within the duodenum, distinct from neoplastic polyps. 1

Diagnosis

  • Endoscopic identification of a polypoid lesion in the duodenum.
  • Histopathological confirmation showing ectopic gastric mucosa.
  • Imaging (e.g., CT, MRI) may be used to assess size and relationship to surrounding structures but is not definitive. 1

    • Management

  • Endoscopic resection: Preferred method using electroresection techniques such as diathermic snare for definitive removal. 1
  • No specific pharmacological treatment mentioned; management primarily surgical/endoscopic.

    • Special Populations

  • No specific data provided regarding pregnancy, pediatrics, elderly, or comorbidities in the given abstracts. 1

    • Key Recommendations

  • Endoscopic resection with electroresection techniques is recommended for definitive management of hyperplastic duodenal polyps composed of ectopic gastric mucosa. (Evidence: Expert opinion) 1
  • Histopathological examination is essential for confirming the diagnosis of ectopic gastric mucosa in duodenal polyps. (Evidence: Expert opinion) 1
