Table 6 The comparison of the length of the operative time between the studied groups. A statistically significant difference was detected; the EAEA group needed a shorter time to finish the procedure taking from 90.00 to 195.00 min, whereas the conventional group consumed longer time ranging from 120.00 to 185.00 min (p = 0.012)
