Two-dimensional (2D) versus three-dimensional (3D) laparoscopy for vaginal cuff closure by surgeons-in-training: a...

Area of Science:

• Minimally Invasive Surgery
• Surgical Education
• Gynecologic Oncology

Background:

• Lack of objective evidence on 3D vision benefits in gynecologic laparoscopy.
• Need to evaluate 3D vs. 2D visualization for vaginal cuff closure during total laparoscopic hysterectomy.
• Focus on surgeons-in-training (senior residents or MIGS fellows).

Purpose of the Study:

• To compare the efficacy of 3D visual systems versus traditional 2D laparoscopic visualization.
• To assess the impact of 3D vision on vaginal cuff closure time during total laparoscopic hysterectomy.
• To evaluate surgeon perception and peri-operative outcomes.

Main Methods:

• Randomized controlled trial involving 51 patients undergoing total laparoscopic hysterectomy.
• Patients randomized to 2D or 3D vision systems for vaginal cuff closure.
• Primary outcome: time for vaginal cuff closure; secondary outcomes: peri-operative results and surgeon ease perception.

Main Results:

• No significant difference in mean vaginal cuff closure time between 2D (10.1 min) and 3D (12 min) systems (p=0.31).
• Increased BMI correlated with longer closure time (p=0.003).
• No difference in surgeon-rated ease of closure or peri-operative outcomes between groups.

Conclusions:

• 3D vision system did not demonstrate superiority over 2D for laparoscopic vaginal cuff suturing by trainees.
• Findings suggest no added benefit of 3D visualization for this specific surgical task in training settings.
• Further research may explore other gynecologic procedures or experienced surgeons.
