Limited thoracotomy for segmentectomy: a comparison of postoperative pain with thoracoscopic lobectomy

Abstract

Purposes

To assess whether a video-assisted thoracoscopic surgery (VATS) procedure is superior to limited thoracotomy (LT) for segmentectomy; postoperative pain was compared between VATS-lobectomy (VATS-L) and LT-segmentectomy (LT-S). Widely opened anterolateral thoracotomy segmentectomy (WT-S) was used as a control.

Methods

This study was a retrospective analysis of prospectively collected data for 220 consecutive patients with stage I NSCLC treated between 2012 and 2015 at a single institute using VATS-L (n = 58), LT-S (n = 93), or WT-S (n = 69). Pain scores from postoperative days (POD) 1–4 were measured using a visual analog scale three times a day. Chronic pain was assessed by the need for analgesics at 1, 2, and 3 months postoperatively.

Results

No significant differences in pain from POD 1 to 4 were observed between VATS-L and LT-S, whereas WT-S showed significantly higher pain scores than these two procedures (p = 0.0001–0.02). Chronic pain did not differ significantly among the procedures.

Conclusion

Postoperative pain does not differ significantly between VATS-L and LT-S. LT may be preferable to VATS for segmentectomy to identify the anatomy, dissect the hilar nodes, and establish surgical margins.
