Thoracic oesophageal perforation, a life-threatening condition, is a therapeutic challenge. A 20 year old male developed a lower oesophageal perforation following an abdominal cardiomyotomy for achalasia of the lower oesophagus. The resulting suppurative mediastinitis and left empyema thoracis were treated by decortication. The oesophageal perforation was closed using a transposition pedicle left latissimus dorsi muscle flap.
