Abstract
BACKGROUND: Three-dimensional (3D) laparoscopic surgery is becoming more popular with the development of laparoscopic devices. The objective of this study was to explore whether the 3D imaging system could improve surgical outcomes of laparoscopic surgery for gastrointestinal cancer compared with the 2D imaging system. METHODS: Systematic literature search was performed using PubMed and Embase databases and relevant data were extracted. Surgical quality, postoperative complications, and postoperative recovery between 3D and 2D laparoscopic surgery groups were compared using a fixed or random effect model. RESULTS: A total of 12 studies involving 1456 patients (3D group 683 patients and 2D group 773 patients) were included in this meta-analysis. The results indicated that mean operation time was significantly shorter in 3D group than in 2D group (WMD, - 9.08; 95% CI, - 14.77, - 3.40; P = 0.002; I2 = 70.3%), especially for gastric cancer patients (WMD, - 14.61; 95% CI, - 26.00, - 3.23, P = 0.012; I2 = 74.1%). In addition, 3D laparoscopic surgery for gastric cancer had an advantage than 2D group in reducing the amount of intraoperative blood loss (WMD, - 13.60, 95% CI, - 21.48, - 5.72; P = 0.001; I2 = 0%). The number of retrieved lymph nodes in 3D group was not significantly different from that in 2D group, regardless of laparoscopic gastrectomy (WMD, 1.10; 95% CI, - 0.67, 2.88; P = 0.222; I2 = 18.8%) and laparoscopic colorectal surgery (WMD, 0.55, 95% CI; - 1.99, 3.09; P = 0.671; I2 = 76.9%). In addition, there was no significant difference between 3D and 2D laparoscopic surgery for postoperative complications and postoperative recovery. CONCLUSION: Main advantages of 3D laparoscopic gastrectomy for gastric cancer were that it could shorten the operation time and reduce the amount of intraoperative blood loss. However, 3D laparoscopic surgery had no obvious advantage over 2D laparoscopic surgery for colorectal cancer patients.
