Sonographic Evaluation and Monitoring of Pneumoperitoneum After Air Enema Reduction for Intussusception.

Abdominal radiography and computed tomography scans are standard tests to diagnose pneumoperitoneum. With the growing availability of point-of-care ultrasound, pneumoperitoneum may be diagnosed in settings without easy access to radiography or computed tomography, such as in overcrowded emergency departments or resource-poor environments. The use of point-of-care ultrasound to diagnose or monitor pneumoperitoneum has been described in adult but not pediatric patients. We present a case of point-of-care ultrasound detection of pneumoperitoneum and monitoring for tension pneumoperitoneum, after failed air enema reduction for intussusception in an infant.
