PS01.130: VIDEO-ASSISTED THORACOSCOPE 3D AND 2D MODE COMPARATIVE ANALYSIS FOR ESOPHAGEAL CHEST SURGERY

Abstract Background To study the advantages and disadvantages of 3D and 2D thoracoscope in the thoracic surgery of esophageal carcinoma. Methods Retrospectively analyze esophageal cancer cases between July 2013 and July 2017 of the first affiliated hospital to Xiamen University, depending on the different mode of Video-Assisted Thoracoscopic, which can be divided into 3D-VATS group 353 cases (observation group) and 2D-VATS group 351 cases (control group). Comparing the difference in operation time, intraoperative bleeding, lymph node transmission, volume of the drain by the first 24 hours, total volume of the drain, chest tube time and postoperative complications. Results All the 704 patients with esophageal cancer were performed under the video-assisted thoracoscope. In terms of surgery time, 3D-VATS group (51.4 ± 13.3min) was shorter than 2D-VATS group (65.7 ± 9.1min), with statistical significance (t = -9.751, P = 0.013); on blood loss, 3D-VATS group (34.1 ± 10.5ml) was less than 2D-VATS group (50.2 ± 9.4ml) with statistical significance (t = -9.274, P = 0.009); about lymph nodes transmission, 3D-VATS group (16.8 ± 3.2) was more than 2D-VATS group (13.1 ± 3.7), with statistical significance (t = 5.213, P = 0.007); in volume of the drain by the first 24 hours, 3D-VATS group (171.2.15 ± 20.2ml) was less slightly than 2D-VATS group (180.3 ± 35.2ml), no statistical difference (t = -1.347, P = 0.281); about total volume of the drain, 3D-VATS group (530.2 ± 53.4ml) was less slightly than 2D-VATS group (553.8 ± 57.5ml), no statistical difference (t = -1.911, P = 0.093); on chest tube time, 3D-VATS group (4.2 ± 0.7d) was less slightly than 2D-VATS group (4.9 ± 1.1d), no statistical difference (t = -1.806, P = 0.069); Postoperative complications in two groups including the incidence of arrhythmia, pulmonary infection, anastomotic leakage and recurrent laryngeal nerve injury has no obvious difference (P > 0.05). Conclusion Video-assisted thoracoscopic surgery of esophagectomy under 3D-mode has certain advantages in operation time, intraoperative bleeding and lymph nodes transmission over 2D-mode. While in the item of volume of the drain by 24 hours, total volume of the drain, chest tube time and postoperative complications, they have no obvious difference.
