The insidious presentation and challenging management of esophageal perforation following diagnostic and therapeutic interventions.

Diagnostic and therapeutic interventions on the esophagus or adjacent organs are responsible for nearly half of all esophageal perforations. If not recognized at the time of the injury, iatrogenic esophageal perforations can present insidiously and lead to delay in diagnosis, thereby increasing morbidity and mortality. Acute clinical awareness is vital for prompt diagnosis, which is usually confirmed with contrast esophagography and contrast-enhanced computed tomography. After establishment of diagnosis, treatment should be promptly initiated and include fluid-volume resuscitation, cessation of oral intake, nasogastric tube insertion, broad-spectrum antibiotics and analgesia. Primary repair, when feasible, is the treatment of choice. Additional procedures beyond primary repair, such as relief of concomitant obstruction, may be necessary if there is underlying esophageal pathology. Drainage alone can be performed for perforations of the cervical esophagus that cannot be visualized. Esophageal T-tube placement or exclusion and diversion techniques are appropriate in clinically unstable patients and in cases where primary repair is precluded either due to preexisting esophageal disease or extensive esophageal damage. Esophagectomy should be performed in patients with malignancy, end-stage benign esophageal disease or extensive esophageal damage that precludes repair. Endoscopic techniques, including stenting, clipping or vacuum therapy, can be used in select cases. Finally, nonoperative management should be reserved for patients with contained esophageal perforations, limited extraluminal soilage and no evidence of systemic inflammation.
