MERITS AND DEMERITS OF THREE REGINAL LYMPH NODE DISSECTION FOR THORACIC ESOPHAGEAL CARCINOMA AND THE LYMPH NODE DISSECTION BY USING THORACOABDOMINO－MIDSTERNAL APPROACH

The 117 cases of two regional (thoraco-abdominal) lymph node dissection were compared to the 56 cases of three regional (with neck area in addition) lymph node dissection for esophageal carcinoma. As for operative death and postoperative complications, there were no difference between these two groups. The prognosis of three regional dissecting group was better than that of two regional dissecting group concerning about the cases that lymphnode metastases were less than 1 or 2, the depth of invasion was limited to just near adventitia (a1) and the locations were in upper or midthoracic esophagus. But also the rate of postoperative recurrence to the neck and uppermediastinal lymph nodes were high in spite of three regional dissection. Putting together with all cases, significant improvement of prognosis were not obtained in the three regional group compared to two regional group. So we thought the usual three reginal lymph node dissection might not be sufficient. Recently we added midsternotomy and made the lymph node dissection in neck-thoracic junction more complete. This procedure did not make the operative death and postoperative complications increase and the improvement of prognosis was expected by it.
