目的：探讨3D腹腔镜肝切除术治疗原发性肝癌的临床应用价值。方法：采用前瞻性非随机对照研究的方法，选择2012年3月—2015年10月间收治的90例原发性肝癌患者，分别行3D高清腹腔镜肝切除术（3D组，48例）和传统2D腹腔镜肝切除术（2D组，42例），比较两组患者相关临床指标。结果：两组患者术前资料具有可比性。两组患者手术方式、术中出血量、术中输血量、术后并发症发生率、术后住院时间、住院总费用方面差异均无统计学意义（均P>0.05），但3D组手术时间明显少于2D组（522 min vs. 566 min，P=0.001）。结论：3D高清腹腔镜肝切除术有助于精准解剖，缩短手术时间，同时不增加副损伤和住院总费用，是一种安全、有效、经济的微创外科手段。
Clinical application value of three-dimensional laparoscopic liver resection for primary liver cancer
Objective: To investigate the clinical application value of three-dimensional (3D) laparoscopic liver resection for primary liver cancer. Methods: Using prospective non-randomized controlled design, 90 patients with primary liver cancer admitted from March 2012 to October 2015 were enrolled and underwent 3D high-definition laparoscopic liver resection (3D group, 48 cases) and traditional two-dimensional (2D) laparoscopic liver resection (2D group, 42 cases) respectively. The main clinical variables between the two groups of patients were compared. Results: The preoperative data were comparable between the two groups of patients. The surgical procedure, intraoperative blood loss, volume of transfusions, incidence of postoperative complications, length of hospital stay and hospitalization costs showed no statistical difference between the two groups (all P>0.05), but the operative time in 3D group was significantly less than that in 2D group (522 min vs. 566 min, P=0.001). Conclusion: 3D high-definition laparoscopic liver resection is helpful in precise dissection and shortening operative time, without increasing associated injuries and total hospitalization costs. So it is a safe, effective, economical and minimally invasive procedure.
