The EEA stapling devices used for intrathoracic anastomosis between the upper esophagus and the gastric tube in patients with carcinoma of the thoracic esophagus were evaluated, and the results were compared with those of an antesternally reconstructed esophagus. These approaches were both used by the same surgical team. An intrathoracic anastomosis using the EEA stapler was made in 53 patients with carcinoma of the thoracic esophagus. Minor anastomotic leakage occurred in five patients (9.4%). Good results were obtained with total parenteral nutrition for 2 weeks. Intrathoracic anastomotic complications were never fatal. Among another 106 patients with antesternally reconstructed esophagus, with the EEA stapler there were 28 patients with anastomotic leakage (26.4%) and two operative mortalities (1.9%). Intrathoracic anastomosis with the EEA stapler is recommended because it is secure and the operative procedure is simple and time-saving. For successful use of the instrument, proper technical procedures must be followed.
