Objectivesalthough video-assisted thoracoscopic surgery for pulmonary resection appears to be associated with more favorable postoperative outcomes than thoracotomy, no reports have discussed its benefit at subsequent reoperative pulmonary resection.Methodsbetween January 2000 and December 2009, 144 patients underwent reoperative pulmonary resections for benign and malignant nodules at the Mayo Clinic, Rochester. Their data were evaluated retrospectively. Twenty-three (16%) patients had prior video-assisted thoracoscopic surgery, and 121 (84%) had undergone a prior open thoracotomy. Intraoperative and short-term postoperative outcomes were analyzed and compared between the two groups, using the chi-square test or Mann-Whitney test.Resultsoverall reoperative mortality was 1.38% and morbidity was 49.3%. Intraoperative factor analysis showed that the prior video-assisted thoracoscopic surgery group more often underwent anatomical resection (p = 0.0011) and showed a tendency towards a lower conversion rate from video-assisted thoracoscopic surgery to thoracotomy at reoperative pulmonary resection (p = 0.051). Short-term postoperative outcomes showed that the prior video-assisted thoracoscopic surgery group had a significantly lower morbidity rate (p = 0.013), significantly shorter hospital stay (p = 0.002), and a tendency for a shorter duration of chest tube drainage (p = 0.09).Conclusionour results suggest that prior video-assisted thoracoscopic surgery may lead to improved postoperative outcomes at subsequent reoperative pulmonary resection. Video-assisted thoracoscopic surgery may be favored for future potential reoperative pulmonary resections.© The Author(s) 2013 Reprints and permissions: sagepub.co.uk/journalsPermissions.nav.
