Summary
Three-dimensional (3D) laparoscopy reduced initial instrument placement time in canine cadaver cholecystectomies. However, 3D and two-dimensional (2D) laparoscopy showed no significant difference in total surgical time or complications.
Area of Science:
- Veterinary Surgery
- Surgical Technology
- Minimally Invasive Procedures
Background:
- Laparoscopic cholecystectomy is a common surgical procedure.
- Advancements in imaging technology, such as three-dimensional (3D) laparoscopy, aim to improve surgical performance.
- The comparative benefits of 3D versus two-dimensional (2D) laparoscopy in specific surgical contexts require investigation.
Purpose of the Study:
- To compare the impact of 3D and 2D laparoscopy on surgical duration and intraoperative complications during canine cadaver cholecystectomies.
- To evaluate specific time intervals within the surgical procedure and assess potential complications.
Main Methods:
- An experimental prospective study was conducted using twelve canine cadavers.
- Laparoscopic cholecystectomies were performed by a single surgeon using either 2D or 3D camera systems.
- Key metrics recorded included time to first endoclip, time between clips, dissection time, total surgical time, cystic duct length, complications, and liver attachment.
Main Results:
- The time from instrument insertion to the first endoclip placement was significantly shorter in the 3D laparoscopy group compared to the 2D group (p = .016).
- No significant differences were observed between the 3D and 2D groups for other recorded surgical times, cystic duct length, intraoperative complications, or liver attachment.
Conclusions:
- Three-dimensional laparoscopy demonstrated a benefit in the initial phase of laparoscopic cholecystectomy by reducing the time to initial clip placement.
- Despite this early advantage, 3D laparoscopy did not lead to a reduction in overall surgical time or complication rates in this canine cadaver model.
- Further clinical research is warranted to determine the broader applicability and optimization of 3D laparoscopy in surgical practice.
