Background: The working space in the upper mediastinum is limited and lymph-node(L.N.) dissection along the left recurrent laryngeal nerve is difficult despite of a clear operative view of the middle and lower mediastinum in prone position VATS-E(Video-Assisted Thoracoscopic Surgery of Esophagus). Anastomosis by a circular stapler in the narrow neck field is difficult. We report our technique of the L.N. dissection along the left recurrent laryngeal nerve and safe anastomosis.
Methods:
-Patients:
One hundred thirty patients (27 in left lateral and 103 in prone position), with esophageal carcinomas underwent VATS-E, respectively.
-Methods:
VATS-E in prone position: At first the patients are fixed at semi-prone position and esophagectomy is performed in prone position that can be set by rotating and 5 ports are used at the intercostal space (ICS). Esophagectomy and the L.N. dissection are performed with pneumothorax by maintaining CO2 insufflation.
L.N. dissection around left recurrent laryngeal nerve: Working space at the left upper mediastinal area for L.N. dissection around recurrent laryngeal nerve is limited in prone position. To obtain the space the residual esophagus is stripped in the reverse direction and retracted toward the neck after the stomach tube is removed through the nose.
Anastomosis: At first the circular stapler is introduced into the gastric conduit and joined to an anvil, and close a little. And then a joined anvil is placed into the proximal esophagus and secured by means of a pursestring suture. The gastric conduit opening is closed by a linear stapler, and the anastomosis is completed.
Results:
1. The rate of permanent and transient recurrent laryngeal nerve paralysis were 2.6% and 22%, respectively.
2. The rate of anastomotic leak and postoperative pneumonia was 4.0% and 2.9%,
Discussion:
1. L.N. dissection along the left recurrent laryngeal nerve after esophageal stripping is available in prone position of VATS-E.
2. Our anastomotic technique is safe.
