| Possible clinical benefits of TaTME over standard laparoscopic surgery need to be discussed in several points. First, trans-anal surgery has undoubtedly superiority regarding its visibility to laparoscopic surgery. The vision from below covered the 360-degree space even in the deep pelvic space. The strength could give us to select an appropriate dissection plane to increase the radical resection rate depending on the tumor site and the depth of invasion. When T3 rectal cancer is located laterally or posteriorly, the CRM positive rate can be reduced by dissecting the plane below the endo-pelvic fascia. Further, from the viewpoint of nerve preservation, since a better recognition of neurovascular bundles and sacral nerves during surgery is higher than that of conventional laparoscopic surgery, the degree of nerve preservation can be more specifically evaluated during surgery. Another strength that TaTME could offer is a two-team operation. There is no doubt about the clinical advantage of two-team surgery dramatically reducing surgery time. Third is the improvement of the anastomosis method. TaTME provides a SST anastomosis by closing the distal rectal stump with a purse-string suture. The method provided us the safe procedures without dog-ear, multiple firing and distal mobilization of the rectum, which were reported to be associated with anastomotic leakages. |
