Three-dimensional versus two-dimensional imaging systems in thoracoscopic lobectomy for lung cancer in different year / 中国医师杂志

ABSTRACT

Objective To compare the clinical application of three-dimensional (3D) and two-di-mensional (2D) imaging systems in thoracoscopic lobectomy for non-small cell lung cancer ( NSCLC). Methods In 2014 and 2016, the patients with NSCLC undergoing thoracoscopic lobectomy with 2D or 3D imaging systems were performed by a single experienced surgeon. The baseline characteristics and perioper-ative data of the patients were collected and analyzed. Results In 2014, 19 patients underwent 3D thora-coscopic lobectomy and the other 23 patients underwent 2D thoracoscopic lobectomy. Compared to 2D thora-coscopic lobectomy group, 3D thoracoscopic lobectomy group had a significantly shorter operative time [(147.0 ±23.9)min vs (179.1 ±54.4)min,P=0.016], a smaller volume of intraoperative blood loss [(142. 1 ± 69. 3)ml vs (203. 0 ± 90. 4)ml,P=0. 018]. In 2016, 36 patients underwent 3D thoracoscopic lobectomy and the other 32 patients underwent 2D thoracoscopic lobectomy. No significant differences were found between two groups in terms of preoperative indicators. Conclusions To some extent, 3D thoracos-copy reduces the operation difficulty, shortens the operative time and reduces intraoperative blood loss. However, with the accumulation of surgical experience, 2D can effectively compensate for the disadvantages of thoracoscope.
