Summary
Surgeon experience significantly impacts laparoscopic cholecystectomy duration, but technical issues and instruments cause most delays. The two-dimensional view has minimal effect on operation time and complications.
Area of Science:
- Minimally Invasive Surgery
- Surgical Outcomes Research
- Medical Device Technology
Background:
- Laparoscopic cholecystectomy is the standard for gallstone treatment.
- Intraoperative difficulties can lead to severe postoperative complications.
- Factors influencing laparoscopic cholecystectomy efficiency require investigation.
Purpose of the Study:
- To analyze the impact of surgeon experience, visualization, instruments, and technical tools on laparoscopic cholecystectomy duration.
- To identify key factors contributing to prolonged operative times.
- To assess the role of the two-dimensional view in surgical outcomes.
Main Methods:
- Ergonomic sequence analysis of 30 laparoscopic cholecystectomies.
- Statistical analysis using the Wilcoxon test.
- Comparison of operative times between experienced and less experienced surgeons.
Main Results:
- Experienced surgeons performed cholecystectomies significantly faster (56 min vs. 75 min).
- Technical tools (40%) and instruments (23.5%) were the primary causes of prolonged operative time.
- Visualization, including the two-dimensional view, had a minor and negligible impact on duration and complications.
Conclusions:
- Surgeon experience partially mitigates time loss and complications.
- Technical and instrumental challenges remain significant barriers to efficient laparoscopic cholecystectomy.
- The two-dimensional view is adequate for safe laparoscopic cholecystectomy procedures.
