Objectives: To assess results of transanal total mesorectal excision laparoscopic surgery for treatment of the middle and low rectal cancer. Subjects and method: Clinical intervention, prospective, follow-up study without comparison in 45 patients with middle and low rectal cancer underwent transanal total mesorectal excision in Gastrointestinal Surgery Department, 108 Millitary Central Hospital, from July 2017 to August 2018. Results: The mean operative time was 145.3 ± 22.5 minutes. Operative morbidity rate was 33.3%, no operative mortality. The macroscopic quality assessment of the resected specimen was complete in 77.8%, nearly complete in 17.8%. The mean number of harvested lymph nodes was 13.8 ± 6.7; the mean follow-up time was 7.47 ± 3.7 months, one patient (2.2%) developed local and distant recurrence, disease-free survival and overall survival rates was 97.7% and 100%, respectively. Conclusion: The transanal total mesorectal excision technique is feasible and safe, the good early outcomes, the high-quality of total mesorectal excision specimens for treatment in middle and low rectal cancer. * Keywords: Rectal cancer; Transanal total mesorectal excision; Laparoscopic operation.
