title: Esophageal resection: indications, techniques, and radiologic assessment.
abstract: Various surgical procedures are performed for benign and malignant esophageal lesions. These procedures include transthoracic esophageal resection through a right or left thoracotomy and transhiatal blunt esophageal resection (esophagectomy) without thoracotomy. The whole stomach, colon, gastric tube, jejunum, and free revascularized grafts may be used as substitutes for the resected esophagus. Bypass procedures including substernal stomach bypass surgery and substernal or subcutaneous colon bypass surgery are performed for tracheoesophageal fistula, previous esophagectomy without reconstruction, or obstruction due to lye ingestion. The mortality rate for esophageal resection depends on the stage of the tumor, the patient's condition, and the surgeon's skill and is quite low when the procedure is performed by a highly skilled surgeon. The most frequent sources of morbidity related to esophageal surgery include pneumothorax, pleural effusion, pneumonia, and respiratory failure. Mediastinitis and sepsis due to disruption at an anastomosis site cause serious postoperative morbidity and mortality; therefore, thoracic anastomotic leaks require aggressive surgical treatment. Familiarity with these surgical options, the resultant anatomic changes associated with each option, and the expected findings at postoperative imaging is essential for evaluating the effectiveness of surgical procedures and for the early detection and management of surgery-related complications.
