PURPOSE: Introduction of three-dimensional (3D) display might remove technical obstacles of laparoscopic surgery and improve laparoscopic skills. We analyzed the effect of 3D technology on operative performance during laparoscopic total gastrectomy (LTG) for gastric cancer and assessed its advantages over two-dimensional (2D) laparoscopy. METHODS: This study included 30 consecutive surgeries of LTG with esophagojejunostomy by the overlap method performed (3D group, n = 15, 2D group, n = 15). The surgical outcomes were compared between the 3D and 2D groups. Further, we compared the performance time, the frequency of bleeding requiring hemostasis, and the frequency of remaking the surgical view by the assistant's forceps in each laparoscopic scene between the 3D and 2D groups. RESULTS: All surgeries were completed without any complications. The total time of pure laparoscopic scenes was shorter in the 3D than 2D group (154.2 vs. 182.7 min, P = 0.026), and total blood loss was almost the same (10 vs. 20 g, P = 0.195). The operative time during lymphadenectomy in scenes 6 and 7 were significantly shorter in the 3D than the 2D group (scene 6, 13.5 vs. 17.5 min, P = 0.003, and scene 7, 12.4 vs. 18.4, P = 0.025) and esophagojejunostomy (30.3 vs. 39.4 min, P = 0.008). The frequency of tissue exposure by the assistant was significantly less in the 3D group than the 2D group in scenes 6 and 7 (scene 6, n = 3.0 vs. 4.0, P = 0.006, and scene 7, n = 3.0 vs. 4.0, P = 0.017). CONCLUSIONS: 3D display is useful due to improvement of surgical skill during difficult situations such as lymphadenectomy around the celiac artery, which requires handling in the tangential view, and reconstruction using the suturing technique in a narrow space.
