[Diagnostics in islet cell tumours (author's transl)].

    Summary

    Diagnosing small pancreatic islet-cell tumors is challenging with standard imaging. Angiography, particularly superselective pancreatico-duodenal artery angiography, is crucial for accurate detection and surgical localization.

    Area of Science:

    • Gastroenterology and Radiology
    • Oncology
    • Vascular Imaging

    Context:

    • Modern imaging techniques like sonography and CT scans often fail to detect small pancreatic islet-cell adenomas.
    • These tumors are typically too small to alter the pancreas's overall shape, making them difficult to visualize with conventional methods.

    Purpose:

    • To highlight the limitations of non-invasive imaging for pancreatic islet-cell adenomas.
    • To emphasize the diagnostic and localizing utility of angiography for these specific tumors.

    Summary:

    • Pancreatic islet-cell adenomas are often missed by sonography and CT due to their small size.
    • Intense vascularization allows for effective diagnosis via angiography, including selective coeliacography, mesentericography, and superselective pancreatico-duodenal artery angiography.
    • Angiography is essential not only for confirming the diagnosis but also for precise tumor localization prior to surgical intervention.

    Impact:

    • Improves diagnostic accuracy for a challenging group of pancreatic tumors.
    • Facilitates surgical planning and execution by providing critical localization information.
    • Enhances patient outcomes through timely and precise intervention for islet-cell adenomas.
