Abstract

Background/Aim: A meta-analysis was conducted to evaluate and compare the short- and longterm outcomes of transanal total mesorectal excision and robot-assisted total mesorectal excision for rectal cancer. Methods: We searched MEDLINE et al. for relevant papers published between 2010 and February 2020 by using specific search terms. For the short-term analysis, we collected data on the perioperative period, clinical course, postoperative complications, and pathological findings. For the long-term analysis, the rates of overall, distant, and local recurrence were examined. Results: We identified 5 papers reporting results that compared transanal total mesorectal excision for rectal cancer with robot-assisted total mesorectal excision. Our meta-analysis included 863 patients with rectal cancer; 348 had undergone transanal total mesorectal excision, and 515 had undergone robot-assisted total mesorectal excision. No significant difference was found in the operative time, conversion rate to laparotomy, and circumferential resection margin between the two groups. The rates of overall recurrence, distant recurrence, and local recurrence were not significantly different. Transanal total mesorectal excision results in almost similar outcomes in the short-term and in the long-term, compared to robot-assisted total mesorectal excision. Conclusion: Transanal total mesorectal excision and robot-assisted total mesorectal excision may be as incomparable as each other as surgical procedures for rectal cancer.
