Each outcome the trial registered, primary first, in ClinicalTrials.gov's words.
| List | Outcome | Time frame | Description |
|---|---|---|---|
| Primary | Median Duration of Coagulation-Mode Electrosurgical Activations During Segment A | During Segment A of the index laparoscopic cholecystectomy | For each operation, the median duration in seconds of individual, clearly separated coagulation-mode activations detected by the locked audio-analysis algorithm during hepatocystic triangle dissection (Segment A). Segment A must contain at least three coagulation-mode activations. The operation is the unit of analysis. |
| Primary | Longitudinal Change in Median Coagulation Activation Duration During Segment A | From the first through the 25th evaluable operation for each longitudinally followed surgeon, up to 31 December 2028 | Change in the operation-level median duration of individual coagulation-mode activations during Segment A for the four longitudinally followed developing surgeons, estimated per 10 additional evaluable laparoscopic cholecystectomies. The effect will be reported as absolute and percentage change with a 95% confidence interval, adjusted for Parkland grade. |
| Secondary | Number of Coagulation-Mode Activations per Minute by Operative Segment | During Segments A and B of the index laparoscopic cholecystectomy | For each operation, the number of detected coagulation-mode activations divided by segment duration in minutes, calculated separately for Segment A and Segment B. |
| Secondary | Total Coagulation Activation Time per Minute by Operative Segment | During Segments A and B of the index laparoscopic cholecystectomy | For each operation, the summed duration in seconds of all coagulation-mode activations divided by segment duration in minutes, calculated separately for Segment A and Segment B. |
| Secondary | Variability of Coagulation Activation Duration by Operative Segment | During Segments A and B of the index laparoscopic cholecystectomy | For each operation, variability in the duration of individual coagulation-mode activations will be summarized using the interquartile range and median absolute deviation, separately for Segment A and Segment B. |
| Secondary | Proportion of Coagulation Activations Longer Than 2 Seconds by Operative Segment | During Segments A and B of the index laparoscopic cholecystectomy | For each operation, the number of coagulation-mode activations lasting more than 2 seconds divided by the total number of coagulation-mode activations, expressed as a percentage and calculated separately for Segment A and Segment B. |
| Secondary | Median Inter-Activation Interval by Operative Segment | During Segments A and B of the index laparoscopic cholecystectomy | For each operation, the median time in seconds from the end of one coagulation-mode activation to the start of the next coagulation-mode activation, calculated separately for Segment A and Segment B. |
| Secondary | Duration of Each Operative Segment | During Segments A and B of the index laparoscopic cholecystectomy | Elapsed time in seconds from the predefined start to the predefined end of Segment A and Segment B, calculated separately for each segment. |
| Secondary | Number of Cutting-Mode Electrosurgical Activations by Operative Segment | During Segments A and B of the index laparoscopic cholecystectomy | For each operation, the number of detected cutting-mode electrosurgical activations, reported descriptively and calculated separately for Segment A and Segment B. |
| Secondary | Median Duration of Cutting-Mode Electrosurgical Activations by Operative Segment | During Segments A and B of the index laparoscopic cholecystectomy | For each operation, the median duration in seconds of individual cutting-mode electrosurgical activations, reported descriptively and calculated separately for Segment A and Segment B. |
