Objective: To prospectively evaluate the short-term outcomes of transanal total mesorectal excision (TaTME) for rectal cancer. Subject and method: 56 patients with middle and low rectal cancer who underwent TaTME in Gastrointestinal Surgery Department, 108 Millitary Central Hospital from July 2017 to December 2018 were included in this study. The data of preoperative staging, tumor’s location, operative morbidity, macropic quality of mesorectal specimen, circumferental resection margin, anal sphincter function were collected. The method popularized by Quirke, Kirwan’s classification was used to assess to quality of mesorectal specimen, the sphincter function respectively. Patients were followed in the outpatient clinic 2 weeks after the surgery and then every 3 months in the first year. Statistical analysis was performed using SPSS 20.0. Result: The mean age of patients was 65.45 ± 11.18 years, the mean BMI was 20.5 ± 2.6kg/m2. The mean operative time was 147.8 ± 22.2 minutes. Operative morbidity rate was 28.6%, there was no operative mortality. The quality of mesorectal specimen was complete in 80.4%, nearly complete in 16.1%. The circumferential resection margin (CRM) was negative in 94.6%; The mean harvested lymph nodes was 8.24 ± 3.17. The mean follow-up time was 10.0 ± 3.9 months, one patient (1.8%) developed local and distant recurrence, disease-free survival and overall survival rates were 98.2% and 100% respectively. The sphincter function at 12 months postoperation assessed by Kirwan was Kirwan I in 58.5% and Kirwan II in 41.2%. Conclusion: The TaTME technique is safe and feasible with acceptable results, especially in the quality of mesorectal specimen and sphincter function.
