Perforation of the cecum from ingested foreign body in a 14 year old adolescent with autism spectrum disorder and epilepsy: A case report.

Introduction And Importance: Although foreign body ingestion is a common medical issue, intestinal perforations following foreign body ingestion are rare. Diagnosing foreign body ingestion is challenging especially in children with neurodevelopmental disorders such as Autism Spectrum Disorder (ASD). It is believed that approximately 80-90% of ingested foreign bodies pass through the gastrointestinal tract without causing any luminal damage, and only approximately 1% of foreign bodies are known to remain lodged within the bowel and cause luminal erosion and perforation.

Case Presentation: A 14-year-old boy, diagnosed to have Autism Spectrum Disorder was brought in by his parents to our hospital with right lower quadrant (RLQ) abdominal pain and fever. On examination, he was tachycardic and there was direct tenderness over the RLQ of the abdomen. Acute appendicitis was entertained and the patient was examined with ultrasound. The ultrasound reported, "The tip of the appendix was dilated (0.62cm) and there is minimal RLQ intra-peritoneal fluid collection". With the impression of acute appendicitis, the patient was explored and he was found to have a cecum perforation due to an ingested foreign body (twig). Initially we did tube cecostomy but later we did right hemicolectomy because the cecostomy tube had leaked.

Conclusion: Foreign body ingestion should be taken into account during the evaluation of children and adolescents with neurodevelopmental disorders who presented with acute abdominal pain. Since diagnosis is difficult clinicians who are involved in acute care medicine should take a thorough history with a high index of suspicion for foreign body ingestion.
