Endoscopic microsurgical dissection of the esophagus (EMDE).
This paper presents endoscopic microsurgical dissection of the esophagus (EMDE), a surgical technique for the therapy of esophageal cancer which improves blunt esophageal dissection with the aim of reducing postoperative morbidity and mortality. A mediastinoscope with integrated operative instrument channel, fibre bundles, optic and rinsing channel has been developed whereby precise and atraumatic esophageal dissection is possible via a cervical access incision. Between 1989 and 1993, 37 patients were operated on using the EMDE technique and are compared with 48 patients operated on during the same period by the thoraco-abdominal route. The operative duration was reduced by the new technique, and although the number of severe complications was not significantly different between both groups, the rate of pulmonary and cardiac complications was reduced. The mortality rate was 10% for EMDE patients and 14% for the thoraco-abdominal procedure, and there was no difference in the long-term survival rate. As distinct from procedures requiring a thoracotomy for esophageal dissection, EMDE permits ventilation of both lungs throughout the entire operation and reduces the total operative trauma.
