Bleeding Meckel's diverticulum diagnosed with 99mTc-pertechnetate

N Iwai, S Ogita, J Yanagihara

    The Japanese Journal of Surgery
    |September 1, 1980

    Summary

    Technetium Tc-99m pertechnetate scans accurately diagnosed bleeding Meckel's diverticulum in children. This imaging technique aids management by ruling out other causes of rectal bleeding.

    Area of Science:

    • Pediatric Surgery
    • Nuclear Medicine
    • Gastroenterology

    Background:

    • Meckel's diverticulum is a common congenital anomaly that can cause significant gastrointestinal bleeding in children.
    • Diagnosing the source of bleeding in pediatric patients can be challenging, necessitating accurate and timely diagnostic tools.

    Observation:

    • Three pediatric cases (11-year-old boy, 8-year-old girl, 2.5-year-old boy) with bleeding Meckel's diverticulum were successfully diagnosed preoperatively using technetium Tc-99m pertechnetate scintigraphy.
    • Abdominal scanning proved valuable in managing patients with rectal bleeding, particularly after other diagnostic modalities like hematologic tests, radiography, and endoscopy had ruled out alternative conditions.

    Findings:

    • Technetium Tc-99m pertechnetate scintigraphy demonstrated high diagnostic value for identifying bleeding Meckel's diverticulum.

  • Optimized scanning protocols, including patient fasting and nasogastric intubation, were employed to minimize artifacts and improve diagnostic accuracy by reducing radioactive gastric juice flow.

    • Implications:

    • Preoperative diagnosis using technetium Tc-99m pertechnetate scintigraphy can significantly improve the management of pediatric patients with Meckel's diverticulum.
    • This imaging modality offers a non-invasive and effective method for identifying ectopic gastric mucosa in Meckel's diverticulum, guiding surgical intervention.
    • The findings support the broader applicability of technetium Tc-99m scintigraphy in the diagnostic workup of obscure pediatric gastrointestinal bleeding.
