Differences between surgeons were borderline non-significant ( p = 0.066) ( Table 2 ).

A positive trend became evident after approximately 20 operations.
When evaluating the cumulative difference between the observed number of successes and the average number of successes at each time to define the learning curve, we found a change from a decreasing trend to an increasing trend in Surgeon A on the 16th surgery ( Figure 2 ).
