    Summary
    This summary is machine-generated.

    Extrapancreatic gastrinomas, a cause of Zollinger-Ellison syndrome, were successfully resected in six patients. Surgical removal led to long-term tumor remission and normalized gastrin levels, offering curative potential.

    Area of Science:

    • Endocrinology
    • Surgical Oncology

    Background:

    • Zollinger-Ellison syndrome is characterized by hypergastrinemia due to gastrinomas.
    • Extrapancreatic gastrinomas present unique diagnostic and surgical challenges.

    Observation:

    • Selective venous sampling identified gastrin hypersecretion sites in five of six patients.
    • Serum gastrin levels and N/C ratios were analyzed preoperatively.
    • All six patients underwent successful surgical resection of gastrinomas, including a liver metastasis in one case.

    Findings:

    • Elevated C-terminal gastrin levels were observed in all patients.
    • Low N/C gastrin ratios (<1.0) were noted in patients without metastases.
    • All patients achieved long-term clinical remission with normalized gastrin levels post-surgery.

    Implications:

    • Curative resection is feasible for select patients with Zollinger-Ellison syndrome and extrapancreatic gastrinomas.
    • Preoperative localization and gastrin level analysis aid surgical planning.
    • Successful outcomes suggest surgical intervention is a primary treatment modality.
