Three-dimensional (3D) visualization provides better outcome than two-dimensional (2D) visualization in single-port...

Area of Science:

• Minimally Invasive Surgery
• Surgical Technology
• Gastrointestinal Oncology

Background:

• Single-incision laparoscopic distal gastrectomy (SIDG) is an evolving minimally invasive technique.
• Current visualization methods for SIDG primarily utilize two-dimensional (2D) systems.
• The application of three-dimensional (3D) vision in SIDG has not been previously reported.

Purpose of the Study:

• To compare the efficacy and outcomes of 3D vision versus 2D vision in patients undergoing SIDG.
• To evaluate the impact of 3D visualization on operative time, blood loss, and postoperative recovery.

Main Methods:

• Retrospective review of 179 gastric cancer patients who underwent SIDG between February 2014 and December 2017.
• Patients were categorized into two groups: 2D camera system (n=90) and 3D camera system (n=89).
• Analysis of operative data and postoperative outcomes, including complications.

Main Results:

• The 3D vision group demonstrated a significantly shorter operative time (115.6 vs. 129.4 min, p=0.012) and reduced estimated blood loss (20.7 vs. 35.1 ml, p=0.034).
• Patients in the 3D group experienced earlier initiation of a small fluid diet (2.5 vs. 3.0 days, p=0.006) and faster discharge (5.4 vs. 6.2 days, p=0.024).
• No significant differences were observed in patient demographics or early/late complication rates between the groups.

Conclusions:

• The implementation of 3D camera systems in SIDG is associated with reduced operative time.
• 3D vision may offer clinical advantages in SIDG, potentially leading to improved patient recovery trajectories.
• Further research is warranted to fully elucidate the benefits of 3D visualization in advanced laparoscopic procedures.
