Objective  To explore application value of three-dimensional (3D) laparoscopic visualization during bariatric surgery. Methods  From January 2015 to May 2017, 64 patients underwent laparoscopic bariatric surgery in our department were included. Among these cases, 19 patients underwent 3D laparoscopic sleeve gastrectomy, and 21 patients underwent two-dimensional (2D) laparoscopic sleeve gastrectomy. Thirteen patients underwent 3D laparoscopic Roux-en-Y gastric bypass, and 11 patients underwent 2D laparoscopic Roux-en-Y gastric bypass. The total operative time, the digestive tract reconstruction time, the intraoperative blood loss, the postoperative hospitalization stay, and the operative complications were analyzed statistically. Results  The laparoscopic bariatric surgery were performed successfully in all the 64 patients, no case was converted to the laparotomy, and no 3D laparoscopy was converted to the 2D laparoscopy. The suture time of the gastric incisal margin was shorter and the intraoperative blood loss was less with the 3D laparoscopic sleeve gastrectomy as compared with the 2D laparoscopic sleeve gastrectomy (P<0.05), but the total operative time and the postoperative hospitalization stay had no significant differences and none of postoperative complications happened between these two modes (P>0.05). The total operative time, the time to make gastric pouch, the time of the gastro-jejunal anastomosis or jejunum-jejunum anastomosis, and the intraoperative blood loss with the 3D laparoscopic Roux-en-Y gastric bypass were significantly less than those with the 2D laparoscopic Roux-en-Y gastric bypass (P<0.05), but the postoperative hospitalization stay had no significant difference between these two modes (P>0.05). Conclusion  Pre-liminary results of limited cases in this study shows that 3D laparoscope could provide 3D stereoscopic visualization, which facilitateto clearly identify anatomical structures, and be helpful to complex operations, and then might reduce operating time, both physicians and patients could benefit from it.
