A comparative study of 3D laparoscopic versus 2D laparoscopic hepatectomy
Objective To explore the application value of three-dimensional（3D）laparoscopic visualization during liver resection. Methods From October 2013 to August2015, 46 patients with liver tumors underwent laparoscopic hepatectomy in our department. Among these cases， 22 patients underwent laparoscopic hepatectomy (LH) by 3D laparoscope，and 24 patients underwent LH by two-dimensional (2D) laparoscope. The surgical methods of LH, the operation time and the intraoperative blood loss, postoperative hospital stay and operative complications were collected and analytic comparation was performed. Results The number of patients who underwent major hepatectomy was 6 (27.3%) in the 3D group and 6 (25%)in the 2D group，and minor hepatectomy was 15（68.2%） in 3D group and 17（70.8%） in 2D group. There was no significant difference between them，respectively. The operative time was significantly shorter in the 3D group when compared to 2D group（150±62 min vs 205±94 min，P=0.024）. No differences were found in intraoperative blood loss （267±233 ml in 3D group vs 289±265 ml in 2D, P=0.774），postoperative hospital stay（7.8±2.7 d vs 8.2±3.2 d，P=0.936），and operative complications（18.2% vs 25%，P=0.575）respectively.Conclusion When compared to 2D laparoscope，3D laparoscope that provides 3D stereoscopic visualizationcan facilitate to identify anatomical structures clearly，and be helpful to complex operations，and then may reduce the operating time.
