Objective: To investigate the classification criterion and surgical treatment strategy of intrathoracic esophageal injury caused by foreign body.
Methods: Eighty-four patients with intrathoracic esophageal injury caused by foreign body in our department from January 1980 to April 2004 were divided into 4 grade: grade I was non-penetrated injury of esophagus (18 cases); grade II was esophageal perforation with mild mediastinitis (39 cases); grade III was esophageal perforation with severe intrathoracic infection (17 cases); grade IV was aortoesophageal fistula (10 cases). Based on the degree of esophageal injury and the extension of inflammation, operative procedures were selected including esophagotomy, esophageal reparation, esophagectomy, mediastinal drainage, reparation of fistula and replacement of aorta.
Results: Patients in grade I and II were all cured . One death occurred in grade III (1/17), the same in Grade IV was 9 (9/10).
Conclusions: Classification of esophageal injury caused by foreign body is helpful to the decision of surgical treatment strategy. The prevention of aortoesophageal fistula is the key point of reducing of mortality.
