ABSTRACT
<p><b>OBJECTIVE</b>To compare the safety and efficacy between two different surgical approaches for thoracoscopic esophagectomy including left lateral decubitus position and prone position.</p><p><b>METHODS</b>From January 2008 to December 2009, 88 patients who underwent thoracoscopic esophagectomy were enrolled in this study. Among them, 52 patients were placed in decubitus position and 36 patients were placed in prone position.</p><p><b>RESULTS</b>No conversion to thoracotomy occurred in either group. The operative time was shorter in the prone group than that in the decubitus group (70 ± 20 min vs. 82 ± 17 min, P<0.01). Blood loss during operation was less in the prone group(100 ± 52 ml vs. 139 ± 54 ml, P<0.01). More lymph nodes were harvested from chest in the prone group(12.2 ± 6.2 vs. 8.6 ± 4.3, P<0.01). There was no significant difference between the two groups in morbidity.</p><p><b>CONCLUSION</b>Thoracoscopic esophagectomy in prone position is associated with better exposure of surgical filed, shorter operative time, less blood loss, and more extensive lymph node dissection as compared to decubitus position.</p>
