“…Lim et al estimated the learning curve for robotic surgeries to be half the number of cases required to attain the same level of profi ciency in laparoscopy (Lim et al 2011 ). Other studies did not fi nd signifi cant difference in learning curve between the robotic and laparoscopic approach (Lenihan et al 2008 ;Yacoub et al 2010 ). Such variation in fi ndings could be due to the differences in prior level of profi ciency in laparoscopic and robotic surgery among the surgeons participating in the study.…”
