3D高清腹腔镜在腹腔镜胃癌根治术中的应用

Application of three-dimensional high-definition laparoscope in laparoscopic radical resection of gastric cancer

目的探讨3D高清腹腔镜在腹腔镜胃癌根治术中的临床应用价值。方法选取我院2013年1月～2013年12月分别采用3D高清腹腔镜（3D组）和2D高清腹腔镜（2D组）行胃癌根治术各40例，对比两组在手术持续时间、术中失血量、学习曲线、住院花费等方面的差异。结果手术持续时间3D高清腹腔镜组2．8±0．6h，明显低于2D高清腹腔镜组3．2±0．8h（P=0．032），两组相比有明显差异（P〈0．05）。术中失血量3D高清腹腔镜组110±18ml，2D高清腹腔镜组120±21ml，两组相比无统计学上差异（P=0．543）。住院花费3D高清腹腔镜组7．5±1．6万元，2D高清腹腔镜组7．1±1.3万元，两组相比无统计学上差异（P=0．162）。结论3D高清腹腔镜能提供清晰的三维立体视觉，良好的深度感，可实现精确操作，缩短手术时间。并且，在3D高清视野下能更陕地提高外科医生的手术操作能力和手术技巧，明显缩短学习曲线。

Objective To investigate the clinical value of three-dimensional （3D） high-definition （HD） laparoscope in laparoscopic radical resection of gastric cancer. Methods From January to December, 2013, 40 patients underwent radical resection of gastric cancer with 3D HD laparoscopy （3D group） and another 40 patients received 2D HD laparoscopy （2D group）. The duration of surger35 intra-operative blood loss, learning curve, and costs during hospitalization were compared between the two groups. Results The average operation duration of 3D group was 2.8±0.6 h, significantly shorter that in the 2D group （3.2±0.8 h, P〈0.05）; the intraoperative blood loss in the 3D group was significantly less than that in the 2D group （110±18 ml vs 120±21 ml, P〉0.05）. The mean hospitalization cost was 75 000±16 000 RMB Yuan in 3D group, similar to significantly lower than that of 71 000 ± 13 000 RMB Yuan in 2D group （P〉0.05）. Conclusion 3D HD laparoscopy can provide three-dimensional vision and better sense of depth to facilitate precise operation and shorten the operation time. The high-definition 3D vision also allows surgeons to quickly improve surgical skills and shorten the learning curve.
