A new concept of endoscopic lung cancer resection: Single-direction thoracoscopic lobectomy.

Although video-assisted thoracoscopic surgery was introduced in the early 1990s, its use in the treatment of lung cancer has been limited. We examined the effectiveness of a simplified surgical method for thoracoscopic lobectomy in patients with lung cancer from May 2006 to October 2007. This novel single-direction thoracoscopic lobectomy was characterized by incisions convenient for the placement of instruments and the lobectomy proceeded progressively in a single direction from superficial to deep structures. The procedure was completed successfully in 26 of 28 patients, with no perioperative deaths. The average operation time was 135min (range, 100-200min), average blood loss was 125mL (range 10-500mL) and average number of lymph nodes dissected was 11.8 (range, 6-23). The average postoperative hospital stay was 7.4 days (range, 5-10 days). Single-direction thoracoscopic lobectomy is a simple, safe, and effective procedure for lobe resection with clear procedural steps. It overcomes the difficulty in manipulation of incomplete lung fissures and potentially extends the indications of thoracoscopic lobectomy.
