Transanal minimally invasive surgery (TAMIS) versus transanal endoscopic microsurgery (TEM): Is one better than the other?

To the Editor,
We read with interest the recent publication by Rimonda et al.  comparing transanal minimally invasive surgery (TAMIS) using a SILS Port (Covidien, Mansfield, MA) with the more traditional transanal platform, transanal endoscopic microsurgery (TEM), for local excision of rectal neoplasms. We congratulate them for their effort to provide the first comparative study of the two platforms. However, an unexplained disparity exists between the findings of this small ex vivo study (n = 10) and the data obtained from multiple clinical series on TAMIS referenced by the authors (combined n = 109).
The first report of using a multichannel port transanally was published by our group in this journal on 21 February 2010, and this approach was named TAMIS . Subsequently, other investigators reported their experience with various multichannel ports [3, 4, 5, 6]. In each of these publications, however, the conclusion was the same: this new approach for transanal surgery is...
