We have read the letter by Dr Petros Mirilas concerning the intertransversalis fascia (TF) approach and appreciate his comments. However, we do not agree that the concept of a bilaminar TF is outdated. Although some scholars state that the TF is a single-layer structure,1 some other scholars,2,3 including Petros Mirilas,4 have described the TF as a bilaminar structure. In our study,5 we observed the 2 layers of the TF not only in laparoscopic operations (see Figures 2-4 in Li et al5) but also in a histological examination (see Figure 6 in Li et al5). That is why we believe that the TF is a 2-layer structure.
