  • • Upper GI endoscopic or contrast radiographic evidence of duodenal tumor



  • • 67% periampullary

    • Risk factors

    • -Crohn disease

      -Ulcerative colitis

      -Polyposis syndromes

      -Villous adenomas

      -Hereditary nonpolyposis colon cancer


  • • Risk factors

    • -Malabsorptive and inflammatory diseases


Gastrointestinal Stromal Tumor (GIST)

  • • 10-30% are malignant

    • Difficult to distinguish benign from malignant on histologic studies

Symptoms and Signs

  • • Abdominal pain

    • GI or biliary obstruction

    • GI bleeding (hematochezia or melena)

    • Weight loss

    Lymphoma: Fever, night sweats

    • Palpable abdominal mass

Laboratory Findings

  • • Anemia

Imaging Findings

  • Barium x-ray studies: Duodenal tumors, particularly those in the third and fourth portions of the duodenum, may be missed

    Endoscopy and biopsy: Usually diagnostic

  • • Symptoms should prompt upper GI contrast radiography or endoscopy and biopsy, which will be diagnostic

Rule Out

  • • Benign duodenal tumors

  • • Signs and symptoms of duodenal tumor

    • Upper GI endoscopy and biopsy will be diagnostic

When to Admit

  • • High grade obstruction

    • Acute upper GI bleeding

    • Severe abdominal pain

    • Obstructive jaundice

  • • Pancreaticoduodenectomy may be necessary for proximal duodenal malignancy



  • • Resect all adenocarcinoma and GIST

    • Resect lymphoma if localized


  • Disseminated lymphoma: Chemotherapy and radiation


  • GIST:Imatinib mesylate

Treatment Monitoring

  • • Endoscopic surveillance after resection


  • • GI and biliary obstruction

    • GI bleeding


  • • After curative resections, the overall 5-year survival rate is 30%

    Adenocarcinoma: 5-year survival stage I, 80%; Stage III, 10-15%.
