“…Kang et al [9], from the Yonsei University College of Medicine in Seoul (South Korea), were the first to describe RATS in 2009. Within a 5-year period, a total of 10,000 RATS procedures (without being able to avoid double counting of procedures reported by the same group in more than 1 publication) have been described in about 31 publications [4,10,11,12,13,14,15,16,17,18,19,20,21,22,23,24,25,26,27,28,29,30,31,32,33,34,35,36,37,38,39].
