    Summary

    Computed tomography (CT) effectively detects pancreatic cancer recurrence after radical pancreatic resection. This imaging technique is crucial for monitoring patients post-surgery, especially in the aortomesenteric region.

    Area of Science:

    • Radiology
    • Surgical Oncology
    • Gastroenterology

    Background:

    • Radical pancreatic resection, including the Whipple procedure and total pancreatectomy, is a complex surgery for periampullary tumors.
    • Postoperative monitoring is essential to detect tumor recurrence, particularly in the aortomesenteric lymph node region.
    • Computed tomography (CT) is a valuable imaging modality for postoperative assessment.

    Purpose of the Study:

    • To evaluate the effectiveness of CT in detecting tumor recurrence and postoperative complications after radical pancreatic resection.
    • To assess the accuracy of CT in identifying recurrence in the critical aortomesenteric region.

    Main Methods:

    • Retrospective analysis of 24 patients who underwent radical pancreatic resection (18 Whipple, 6 total pancreatectomy).
    • Patients were evaluated using CT scans from one week to 11 years post-surgery.
    • Glucagon was administered prior to CT to enhance visualization of the afferent jejunal loop and upper quadrant anatomy.

    Main Results:

    • CT demonstrated postoperative complications or tumor recurrence in 16 out of 24 patients.
    • The aortomesenteric region was identified as a key area for detecting recurrence.
    • CT showed 100% accuracy in detecting recurrence in patients with follow-up.

    Conclusions:

    • CT is a highly accurate and effective tool for detecting tumor recurrence and postoperative complications following radical pancreatic resection.
    • The aortomesenteric region is a critical surveillance area due to the propensity of periampullary tumors to metastasize to these lymph nodes.
    • CT facilitates early detection of recurrence, aiding in patient management and prognosis.
