Objectives: To compare the effectiveness of single-port and double-port thoracoscopic lobectomy in the treatment of non-small cell lung cancer (NSCLC) using meta-analysis.
Methods: We systematically searched Pubmed, Embase, and Cochrane Library databases to collect literature on single-hole and double-hole thoracoscopic lobectomy for NSCLC with the end date of August 2022. Keywords included "thoracoscopy", "lobectomy", and "non-small cell lung cancer". Two authors independently conducted literature screening, data extraction, and quality evaluation. The quality evaluation tools were the Cochrane bias risk assessment tool and the Newcastle-Ottawa scale. Meta-analysis was performed using RevMan5.3 software. The odds ratio (OR), weighted mean difference (WMD), and 95% Cl were calculated using a fixed-effects model or random-effect model as appropriate.
Results: Ten studies were included. These included two randomized controlled studies and eight cohort studies. 1800 sick persons were included in the survey. Among them, 976 sick people underwent single-hole thoracoscopic lobectomy (single-hole group), and 904 had double-hole thoracoscopic lobectomy (double-hole group). The results of the meta-analysis are as follows. The intraoperative bleeding volume [WMD = -13.75, 95% CI (-18.47, -9.03), P < 0.001], postoperative 24 h VAS score [WMD = -0.60, 95% CI (-0.75, -0.46), P < 0.001], and postoperative hospital stay time [WMD = -0.33, 95% CI (-0.54, -0.11), P = 0.0003] in the single-hole group was less than that in the double-hole group. The amount of dissected lymph nodes in the double-hole group was more than that in the single-hole group [WMD = 0.50, 95% CI (0.21, 0.80), P = 0.0007]. In both groups, operative time [WMD = 1.00, 95% CI (-9.62, 11.62), P = 0.85], intraoperative conversion rate [OR = 1.07, 95% CI (0.55, 2.08), P = 0.85], postoperative drainage time [WMD = -0.18, 95% CI (-0.52, -0.17), P = 0.32], and postoperative complications rate [OR = 0.89, 95% CI (0.65, 1.22), P = 0.46] had no statistical significance.
Conclusion: Single-hole thoracoscopic lobectomy has advantages in reducing intraoperative bleeding volume, alleviating early postoperative pain, and shortening postoperative hospital stay time. Double-hole thoracoscopic lobectomy has advantages in lymph node dissection. Both methods are equally safe and feasible for NSCLC.
