Does failed video-assisted lobectomy for lung cancer prejudice immediate and long-term outcomes?
BACKGROUND
Lobectomy for lung cancer by video-assisted thorascopic surgery (VATS) remains an infrequently performed operation despite numerous publications showing the benefits of successful VATS compared with an open thoracotomy approach. However, concern remains regarding patient safety, notably the need for emergency intraoperative conversion to open thoracotomy leading to potential adverse consequences. We therefore compared the outcomes of converted VATS patients with open thoracotomy controls.


METHODS
Between May 1992 and April 2006, 30 of 286 VATS lobectomies for lung cancer required intraoperative conversion to open thoracotomy. Four patients were of advanced stage and excluded from the study. The remaining patients were matched 2:1 with open thoracotomy controls by age, sex, cancer stage, year, and type of operation. Postoperative complications and pathology were determined from the hospital discharge summary and pathology report. Long-term survival information was obtained from the family doctor or central registry.


RESULTS
There were no statistically significant differences in postoperative complications between the two groups (p = 0.093). There were no in-hospital deaths in the converted VATS group. Kaplan-Meier survival analysis for cancer-related or unassociated death demonstrated no statistically significant difference (log-rank p = 0.1627).


CONCLUSIONS
Conversion during attempted VATS resection does not prejudice short-term or long-term surgical outcomes. We therefore suggest that VATS lobectomy should be the treatment strategy of choice for stage I and II non-small cell lung cancer in view of the well-established short-term benefits and equivalent survival associated with successful VATS resection.
