Objective To design a technique of esophagus-stomach-abdominal wall drainage for the de-layed intrathoracic esophageal perforation and to improve the therapeutic results. Methods Four patients were treated by this simplified technique. There were 1 case of lower intrathoracic esophageal perforation to the left thorax , 1 high and 2 middle perforation to the right. This technique used two plastic tubes (chest tube) in a diameter about 1 .2cm . One tube served as an intercostal drainage tube to drain purulent effusion , the other was inserted abdominally through stomach to the esophagus about 10cm above the esophageal perforation. Results The four patients were treated successfully by the esophagus-stomach-abdominal wall drainage. There was no mortality or severe morbidity or complication. Hospitalizations were shortened. Conclusion This technique is simple, safe and effective. It may provide a more promising alternative method of treatment for delayed esophageal perforation, especially in the critically ill patients. The procedure can also be extended to deal with esophagus-stomach anastomotic leak. 展开更多
