Duodenal polyps: diagnosis and management

Area of Science:

• Gastroenterology
• Endoscopy
• Surgical Pathology

Background:

• Duodenal polyps are uncommon gastrointestinal findings.
• Accurate diagnosis and management are crucial due to potential malignancy.

Purpose of the Study:

• To evaluate the diagnostic utility of upper gastrointestinal X-rays versus duodenoscopy for duodenal polyps.
• To characterize the types and outcomes of duodenal polyps identified.
• To assess the efficacy of endoscopic polypectomy for duodenal lesions.

Main Methods:

• Retrospective review of 45 duodenoscopies performed between 1973 and 1978.
• Comparison of findings with upper gastrointestinal X-ray results.
• Histopathological analysis of biopsied polyps.
• Documentation of surgical and endoscopic interventions.

Main Results:

• Upper gastrointestinal X-rays missed small duodenal polyps but identified larger lesions or masses.
• Histological diagnoses included adenomatous polyps, villous adenomas, Brunner's gland hyperplasia, lipomas, and carcinoid tumors.
• Villous adenomas demonstrated characteristic endoscopic features, aiding diagnosis.
• Pedunculated polyps were safely removed via endoscopic snare excision.

Conclusions:

• Endoscopic evaluation is superior to X-ray for detecting small duodenal polyps.
• Villous adenomas require excision due to malignant potential.
• Endoscopic snare excision is a safe and effective treatment for pedunculated duodenal polyps.
