Abstract
Esophageal anastomotic leaks remain the most serious problem following extirpative procedures for esophageal carcinoma. We conducted a retrospective analysis of 352 patients with carcinoma in the thoracic esophagus who had undergone esophageal anastomosis following esophagectomy at the Kurume University Hospital between 1981 and 1990. Of these, 94 patients (27%) developed anastomotic leaks, and out of this subgroup, 21 (6%) died as a direct result of the leak. A further 20 patients (6%) underwent repair of the leak, after which they were able to tolerate oral intake. The anastomotic leak healed spontaneously in the other 53 patients (15%). The risk factors predisposing to leaks from esophageal anastomoses were determined as: (1) the anastomosis being performed via a retrosternal or subcutaneous route as opposed to an intrathoracic route, (2) the use of colonic interposition as opposed to a gastric pedicle, (3) performing a manual anastomosis as opposed to a mechanical anastomosis, and (4) employing an end-to-end anastomosis, as opposed to an end-to-side anastomosis, using a mechanical method. By introducing an anastomotic stapling device, a microvascular technique, a staged operation based on the preoperative risk analysis, and improvement in pre- and postoperative management, the incidence of anastomotic leakage could be decreased from 35% to 14%, and that of consequent hospital mortality, from 9% to 2%.
