Abstract

Background:

Thoracoscopic esophagectomy for esophageal cancer has been performed as an alternative to open surgery to reduce surgical trauma. However, its effect on pulmonary function, exercise tolerability, and quality of life is unknown.

Methods:

Fifty-one patients with esophageal cancer underwent thoracic esophagectomy with radical lymphadenectomy by posterolateral thoracotomy (29 cases) or thoracoscopic surgery (22 cases). Patients performed spirometry and exercise tolerance testing and completed a quality-of-life questionnaire before and 3 months after surgery.

Results:

Pre-to-postoperative change in vital capacity was 74.3 ± 10.6% in the thoracotomy group and 84.9 ± 10.4% in the thoracoscopy group (p = 0.021). Maximum oxygen uptake was similar, but dyspnea was the more common factor limiting exercise tolerance postoperatively in the thoracotomy group. Change in pre-to-postoperative performance status was 1.20 ± 0.62 in the thoracotomy group and 0.55 ± 0.51 in the thoracoscopy group (p = 0.0003).

Conclusions:

Thoracoscopic esophagectomy for esophageal cancer has better preservation of pulmonary function and quality-of-life.
