Does 3D laparoscopy make surgery faster for an adult Inguinal Hernia?
For adults undergoing laparoscopic inguinal hernia repair, the type of camera system used can affect how long the surgery takes. 3D laparoscopy provides depth perception that 2D systems lack, which may help surgeons work more efficiently. A 2025 systematic review and meta-analysis found that 3D laparoscopy significantly shortens operative time compared to 2D laparoscopy for transabdominal preperitoneal (TAPP) repair, a common technique for inguinal hernia.
What the research says
A 2025 meta-analysis of 5 studies involving 521 patients found that 3D laparoscopy reduced total operative time by an average of 18.48 minutes compared to 2D laparoscopy for adult inguinal hernia repair 1. This benefit was seen in both randomized controlled trials (average reduction of 11.70 minutes) and observational studies (average reduction of 26.85 minutes) 1. The 3D system also improved contrast perception, though sharpness was not significantly different 1. No difference in postoperative complications was found between the two systems 1. These findings are specific to 3D versus 2D laparoscopy; other comparisons, such as laparoscopic versus open repair, show mixed results on operative time depending on the patient group 67. For example, a 2025 trial in elderly patients found similar operative times between laparoscopic TEP and open repair (about 36 minutes each) 7.
What to ask your doctor
- Is 3D laparoscopy available at your hospital for inguinal hernia repair?
- Would I be a good candidate for 3D laparoscopic TAPP repair?
- How much does the operative time difference matter for my specific case?
- Are there any extra costs or risks associated with 3D laparoscopy?
- What is your experience with 3D versus 2D laparoscopy for this surgery?
