ABEDRAPO M, Mario et al. Transanal total mesorectal excision in rectal cancer: Analysis of a preliminary series in universitary hospital. Rev Chil Cir [online]. 2017, vol.69, n.1, pp.53-59. ISSN 0718-4026.  http://dx.doi.org/10.1016/j.rchic.2016.07.006.

Introduction: Transanal total mesorectal excision is a hybrid approach that combines the use of a conventional laparoscopic and a transanal platform. Objectives: To conduct an analysis of selected cases with medium and lower rectal cancer, were a combined transanal approach was used and description of the surgical technique. Materials and methods: Prospective series of patients diagnosed with middle and lower third rectal cancer with mesorectal resection assisted by endoanal single port, between October 2012 and December 2015 at University of Chile Clinical Hospital. Descriptive statistics were used for data analysis. Results: A total of 29 patients underwent surgery for middle and lower rectal cancer using a transanal single port. Gender distribution was 22 male and 7 female patients, with a mean age of 55.5 years and a mean BMI of 26.4. The mean distance from the anal margin was 4.8 cm. All patients received neoadjuvant therapy. The surgeries performed were 17 Ta-TME (58.6%) and 12 Ta-TME with intersphincteric approach (41.4%). The colo-anal anastomosis was hand sewn in 15 patients (51.7%), and stapled in 14 (48.3%). The laparoscopic approach was used in 26 patients and the open approach in 3, with 4 conversions (15.4%). The mean operative time was 282 min. The mean hospital stay was 9 days. Conclusion: The endoanal single port appears as a useful tool in total mesorectal dissection for its safety and feasibility. We believe we need randomized prospective studies, where comparison of oncological and functional long-term results is relevant.
