Feasibility of video-assisted thoracoscopic surgery segmentectomy for selected peripheral lung carcinomas

Objective: Segmentectomy for non-small cell lung cancer (NSCLC) is believed to increase the rates of recurrence and postoperative air leak. We sought to present our clinical data and outcome of VATS (video-assisted thoracoscopic surgery) segmentectomies with systematic node dissection for selected NSCLC patients. Methods: Inclusion criteria were clinical T1N0M0 peripheral NSCLC measuring 2c m (n = 38) and NSCLC with interlobar invasion, which cause positive surgical margin with malignancy after lobectomy of a primary lesion and only partial resection of invasion site (n = 3). Outcome variables include hospital course, complications, mortality, recurrence patterns and survival. The intersegmental border was identified using the intersegmental veins as landmark and the demarcation between the resected (inflated) and preserved (collapsed) lungs. The intersegmental plane was divided by an endoscopic stapler and electrocautery. Results: The mean operative time and intraoperative bleeding were 220 min (range 100—306)and183 ml(30—730),respectively. The numberof stapler cartridgesused for intersegmental division was 2(1—5).Postoperativeairleak(>7 days),whichrequirednosurgicalintervention,occurredintwopatients.Thechesttubedrainageduration was 3 days. There were no in-hospital deaths. The numbers of resected subsegments and reserved subsegments in comparison with lobectomy were 5 (2—13) and 5 (3—13), respectively. The FEV1.0 after VS was higher than the predictive FEV1.0 after lobectomy, if the latter was performed as standard procedure. We experienced four cases of distant metastasis after segmentectomy, but there was no case of local recurrence. The 5-year survival and recurrence-free survival rates in pathological stage IA NSCLC were 89.9% and 93.3%, respectively. Conclusions: VATS segmentectomy with systematic node dissection is a reasonable treatment option for selected peripheral NSCLC. # 2009 European Association for Cardio-Thoracic Surgery.
