OBJECTIVE: We investigated the merits and demerits of right cervical open surgery with right trans-cervical pneumomediastinal approach in mediastinoscopic esophagectomy.
METHODS: Ten thoracic esophageal cancer patients were treated using this approach. Under pneumomediastinum via a right neck incision, the right cervical and upper mediastinal paraesophageal lymph nodes were dissected. The left recurrent nerve lymph nodes were dissected using a left trans-cervical pneumomediastinal approach. The subaortic arch to the left tracheobronchial lymph nodes was dissected with a combined right and left trans-cervical crossover approach.
RESULTS: The average number of dissected lymph nodes among the right cervical and upper mediastinal paraesophageal lymph nodes identified with a right cervical open/right trans-cervical mediastinoscopic/right thoracoscopic approach was 3.2/4.0/0.6, respectively. The average number of dissected lymph nodes among the subaortic arch to the left tracheobronchial lymph nodes with a right trans-cervical mediastinoscopic/right thoracoscopic approach was 1.5/0.6, respectively. These findings indicate that, without using the right trans-cervical pneumomediastinal approach, it might be impossible to successfully remove some of the right cervical and upper mediastinal paraesophageal lymph nodes and the subaortic arch to the left tracheobronchial lymph nodes lymph nodes. Regarding surgical complications, one case of bilateral recurrent nerve palsy as well as two cases on the right and two cases on the left were noted.
CONCLUSIONS: Although the rate of recurrent nerve palsy should still be reduced, a bilateral (especially right-sided) trans-cervical pneumomediastinal approach is an available option for achieving sufficient upper mediastinal lymph node dissection and esophagectomy.
