    A persistent benign pneumoperitoneum was observed in a patient for two years without gastrointestinal issues. The cause of free abdominal air remained unclear, possibly from colonic microperforations.

    Area of Science:

    • Gastroenterology
    • Abdominal Imaging
    • Clinical Case Study

    Background:

    • Pneumoperitoneum, defined as free air in the abdominal cavity, typically indicates a surgical emergency due to potential gastrointestinal perforation.
    • Benign causes of pneumoperitoneum are rare and require careful differentiation from emergent conditions.

    Observation:

    • A 68-year-old patient presented with persistent pneumoperitoneum over a two-year observation period.
    • No evidence of gastrointestinal perforation, pneumatosis cystoides intestinalis, or peritonitis was found.
    • The free air was a benign finding without associated adverse effects.

    Findings:

    • The study documents a rare case of prolonged benign pneumoperitoneum.
    • The exact source of the free air could not be definitively identified.

  • Potential etiologies include microperforations in colonic diverticula or a distended intestinal wall.
  • Implications:

    • This case highlights the importance of considering benign causes of pneumoperitoneum, even when persistent.
    • Further investigation into the mechanisms of benign air leakage from the bowel may be warranted.
    • Accurate diagnosis can prevent unnecessary surgical intervention for benign conditions.
