Abstract

Background

Due to the technological advance in resolution and stereoscopic depth, the 3-dimensional (3D) laparoscopic system has been widely used in real surgery. However, there have been few studies to confirm the clinical usefulness of the 3D laparoscopic distal gastrectomy (LDG). This study aimed to compare perioperative outcomes between the 2-dimensional (2D) and 3D LDG for gastric cancer patients.

Methods

This was a prospective, randomized controlled, single-center, and superiority trial. This study was carried in Seoul National University Bundang Hospital. Patients with histologically confirmed gastric adenocarcinoma which could be radically resected by LDG were randomly assigned (1:1) to the 2D or 3D group. From October 2016 to August 2018, 84 patients were included in this study and randomly assigned into the 2D group (44 patients) or the 3D group (40 patients). A total of 5 patients were excluded; 3 in the 2D group and 2 were in the 3D group. Consequently, the data from 79 patients were analyzed (2D: 41 cases; 3D: 38 cases). For the LDG procedure, 3D and 2D camera and display system were applied according to the assigned group. The primary end point was the duration of total laparoscopic operation time. Secondary end points included the amount of intraoperative blood loss (IBL), the number of harvested lymph nodes, postoperative complications and open conversion rate.

Results

There were no differences between 2 and 3D groups with respect to clinicopathologic characteristics. The total operation time in 3D groups was significantly shorter than 2D group (122 [106.5–161] versus 101 [77.75–125.5] minutes; P = 0.001). The postoperative complication rates in the 3D groups was significantly lower than 2D group (24.4% versus 7.9%, respectively; P = 0.045).

Conclusion

3D LDG shorten the operation time compared with 2D LDG in gastric cancer patients. And 3D laparoscopy provided the benefit of less postoperative complications.
