The Influence of Micropauses on Surgeons' Precision After Short Laparoscopy Procedures
Unlabelled:
It has recently been shown that micropauses during long surgical procedures can be beneficial for surgeons' precision and fatigue. The aim of the study was to evaluate the impact of micropauses on surgical precision measured by a simple smartphone application.
Material And Methods:
Two surgeons performed 40 simple laparoscopic procedures (appendectomy and cholecystectomy) with or without micropauses. After the operation the precision of surgical movements was measured by a simple smartphone application in which the number of successful trials and their mean time were used as a precision surrogate.
Results:
Mean number of successful trials was significantly higher for appendectomy than for cholecystectomy (5.59 vs 4; p = 0.032). There was a difference between participating surgeons both in terms of number of successful trials (5.80 vs 3.55; p = 0.01) and a mean time of all successful trials (10.03 vs 6.28; p = 0.001). No other statistically significant differences were identified.
Conclusion:
Micropauses had no influence on surgical precision as evaluated after short laparoscopy procedures. The only differences were surgeon-dependent and intervention-dependent.
Insights
Micropauses did not improve surgical precision in short laparoscopic procedures. Performance differences were mainly due to the surgeon and the specific surgical intervention, not the breaks.
Area of Science:
- Surgical Innovation
- Minimally Invasive Surgery
- Medical Device Technology
Background:
- Surgeons' precision and fatigue are critical during lengthy surgical procedures.
- Recent evidence suggests micropauses may enhance surgeon performance.
- The impact of micropauses on objective surgical precision remains under investigation.
Purpose of the Study:
- To evaluate the effect of micropauses on surgical precision.
- To assess surgical precision using a smartphone application.
- To determine if micropauses influence performance in laparoscopic surgery.
Main Methods:
- Two surgeons performed 40 laparoscopic procedures (appendectomy, cholecystectomy) with and without micropauses.
- Surgical precision was quantified post-operatively using a smartphone application.
- Key metrics included the number of successful trials and mean time for successful trials.
Main Results:
- No statistically significant difference in surgical precision was observed with micropauses.
- Appendectomy procedures showed higher mean successful trials than cholecystectomy (p=0.032).
- Significant differences in precision metrics were noted between the two surgeons (p=0.01, p=0.001).
Conclusions:
- Micropauses did not influence surgical precision in short laparoscopic procedures.
- Surgical precision was primarily dependent on the individual surgeon and the type of procedure.
- Smartphone-based precision measurement offers a novel approach for surgical assessment.
