Objective: The purpose of this study was to establish step-by-step procedures of taTME and to avoid intraoperative complications. Methods: We experienced one-hundred thirty taTME operations for low rectal cancers since 2013. We divided whole procedure to nine parts according to the surgical anatomical feature to establish step-by-step taTME.
Results: There are longitudinal fibers, deriving from the outer longitudinal muscle of the rectum, which attach to the Endopelvic fascia throughout a whole circumference. Especially, the smooth muscle fibers were recognized during surgery as the recto-urethral muscle in the anterior side and the recto-coccygeal muscle in the posterior side. So we should dissect at 1 and 11 o'clock first to identify the recto-urethral muscle clearly. This step could avoid the urethral injury. As well, we need to dissect at 5 and 7 o'clock first to identify the recto-coccygeal muscle in posterior side. We had no experiences of the urethral injury and our average operative time of taTME by two teams was 128 min.
Conclusion: The step-by-step taTME could offer safe and quick procedures according to the surgical anatomies closed to the anal ring in rectal cancer.
