THORACOSCOPIC ESOPHAGECTOMY - TECHNIQUE AND INITIAL RESULTS

To reduce the high morbidity rate associated with esophageal surgery, we have developed a technique of thoracoscopic esophagectomy. A feasibility study was first carried out in an animal model and a specific instrument was developed for this purpose. Esophagectomy using a right thoracoscopic approach was attempted in 15 patients, 13 males and 2 females whose average age was 48 years. Indications consisted of squamous cell carcinoma in 10 patients, adenocarcinoma in 1, and caustic stenosis in 4. We used a technique that consisted of double-lumen tracheal intubation and the creation of five ports. The whole esophagus was mobilized thoracoscopically and the esophagectomy was completed through the abdomen. The reconstruction was achieved using a gastric pull-through, and the anastomosis was made in the neck. There were three failures: in 1 patient there was a large tumor, making the exposure unsafe, and, in 2 patients, incomplete lung collapse made exposure of the posterior mediastinum difficult. These 3 cases were converted into a thoracotomy. The thoracoscopic dissection was successful in the remaining 12 patients. The average time of the thoracoscopic stage was 125 minutes. The postoperative course was uneventful in 10 patients. Two patients had a left atelectasis. Although our series is limited, these initial results indicate that thoracoscopic esophagectomy is feasible. However, further evaluation of the technique is needed to assess its benefit in terms of respiratory morbidity.
