Subcutaneous Facial and Neck Emphysema as First Sign of Intestinal Perforation in a Female Patient After a Routine Colonoscopy.

Colonoscopy is a safe procedure for the diagnosis and management of colorectal diseases. Colonic perforation due to colonoscopy represents an uncommon complication. Here we present an unusual case of iatrogenic bowel perforation resulting in subcutaneous facial and neck emphysema, pneumomediastinum and pneumoretroperitoneum. Taking a detailed recent medical history information is always required when encountering patients with subcutaneous emphysema after invasive examination procedures. Alertness on iatrogenic complication eventualities may improve prognosis and avoid life-threatening conditions.
