title: Technique for delivering large tumors in video-assisted thoracoscopic lobectomy.
abstract: BACKGROUND
  The optimal technique for delivering large tumors during video-assisted thoracoscopic lobectomy remains uncertain.
  
  
  METHODS
  In 258 patients receiving video-assisted thoracoscopic lobectomy for lung cancer, techniques for delivering the resected lobe included complete video-assisted thoracoscopic lobectomy without rib spreading (n = 206, 80%), resection of a short rib segment (n = 9, 3%), brief rib spreading (n = 12, 5%), and conversion to a minithoracotomy (n = 21, 8%). In 10 (4%) patients, a novel anterior rib cutting technique was used: one rib at the utility port was cut near its anterior end to widen the intercostal space without forcible rib spreading for lobe delivery.
  
  
  RESULTS
  There was no mortality or major morbidity using the anterior rib cutting technique, and it delivered tumors of a larger mean diameter than complete video-assisted thoracoscopic lobectomy (5.4 ± 3.4 vs. 2.3 ± 1.4 cm, p = 0.017) whilst yielding a similar mean operation time and blood loss to the other non-complete video-assisted thoracoscopic lobectomy techniques. The anterior rib cutting technique gave similar postoperative patient pain scores and analgesic use to complete video-assisted thoracoscopic lobectomy, and shorter mean hospital stay than the other non-complete video-assisted thoracoscopic lobectomy techniques (5.6 ± 2.8 vs. 10.0 ± 7.1 days, p = 0.003).
  
  
  CONCLUSIONS
  In video-assisted thoracoscopic lobectomy, the anterior rib cutting technique is a safe and feasible procedure for delivering large tumors, causing no more pain than complete video-assisted thoracoscopic lobectomy, and allowing faster recovery than other non-complete video-assisted thoracoscopic lobectomy techniques.
