Purpose: Because conventional laparoscopic rectal surgery is difficult due to narrow pelvix, then the new surgical method, Transanal Total Mesorectal Excision (TaTME) has been developed for middle or low rectal cancer. This study to evaluate the safety and short-term outcome of TaTME for rectal cancer.
Materials and Methods: We enrolled 37 patients with rectal cancer diagnosed in China Medical University Hospital from January 2016 to August 2017. All the patients received TaTME for rectal cancer. The clinicopathological and surgical data of these patients were prospectively collected and analyzed.
Results: Of 37 patients, 70.3% were men. The mean age of all patients was 64.3years-old. 46% of rectal tumor were located at middle rectum and 51% were located at low rectum. 67.6% of patients received neoadjuvant chemoradiation. Median operative time was 335 mins. Median distal margin was 1.9 cm. Positive circumferential margin rate was 2.6%. Three patients underwent intraoperative complication, urethra injury, vaginal perforation, and left internal iliac artery injury. Median harvested lymph nodes were 14.1. The anastomotic leakage rate was 18.9%. Median hospital stay was 7.1 days. Median days of urinary catheterization was 2.3 days. There were 18.9% of patients who needed urinary re-catheterization. Three patients discharged with Foley catheter.
Conclusion: Although conventional laparoscopic rectal surgery is difficult, transanal total mesorectal excision for middle and low rectal cancer is the alternative method and it is feasible and safety. It can provide good short-term clinical and oncological outcomes.
