    Radiation therapy can cause long-term intestinal pseudoobstruction due to damage to the small bowel's muscles and nerves. This case highlights a rare, delayed complication of abdominal irradiation.

    Area of Science:

    • Gastroenterology
    • Oncology
    • Pathology

    Background:

    • Intestinal pseudoobstruction is a condition that mimics bowel obstruction without a physical blockage.
    • Abdominal radiation therapy is a common treatment for various cancers.
    • Delayed complications of radiation therapy can affect multiple organ systems.

    Observation:

    • A patient presented with symptoms of intestinal pseudoobstruction 30 years after receiving abdominal radiation therapy.
    • Surgical exploration ruled out mechanical causes of obstruction.
    • Histological examination of the small bowel revealed significant pathological changes.

    Findings:

    • Histology showed vascular ectasia, sclerosis, serosal fibrosis, submucosal neuronal proliferation, and degeneration of circular muscle fibers.

  • These findings indicate chronic injury to the small bowel's vasculature, nerves, and musculature.
  • The observed changes are consistent with radiation-induced damage.

    • Implications:

    • Abdominal radiation can lead to severe, long-term gastrointestinal complications like pseudoobstruction.
    • This case underscores the importance of considering radiation history in patients with late-onset intestinal dysfunction.
    • Further research into the mechanisms and management of radiation-induced enteropathy is warranted.
