    Abstract:
    BACKGROUND: This study aimed to compare perioperative, long-term oncological, and anorectal functional outcomes of robotic total mesorectal excision (R-TME) and laparoscopic total mesorectal excision (L-TME) sphincter-saving total mesorectal excision in female patients with rectal cancer. METHODS: Retrospective analysis of prospectively maintained database was performed. Sixty-eight cases (L-TME, n = 34; R-TME, n = 34) were performed by a single surgeon (January 2014-January 2019). Patient characteristics, perioperative recovery, postoperative complications, pathology results, and oncological outcomes were compared between the two groups. RESULTS: Clinical characteristics did not differ between the groups. Mean operating time was longer in R-TME (165.50 ± 95.50 vs. 124.50 ± 82.60 min, p < 0.001). There was no conversion to open surgery in both groups. Mesorectal integrity was complete in both groups (100%). Length of distal and circumferential resection margins (CRM) did not differ between groups. CRM involvement was observed in 1 (2.8%) and 1 (2.8%) in L-TME and R-TME patients, respectively. Incidence of anastomotic leakage was 5.8% (n = 2) in L-TME and 8.8% (n = 3) in R-TME, respectively. Mean length of follow-up was 62.5 (36-102) months for R-TME and 63 (36-103) months for L-TME. Five-year overall survival rates were 92.8% in L-TME and 89.6% in R-TME. Disease-free survival rates were 87.5% in L-TME and 89.6% in R-TME. Local recurrence rates were 3.0% for both groups. Mean Wexner score for L-TME and R-TME patients was: 9.42 ± 8.23 and 9.22 ± 3.64 (p = 0.685), respectively. Daily stool frequency was similar between groups. CONCLUSION: Robotic total mesorectal excision (R-TME) and laparoscopic TME (L-TME) have similar perioperative, oncological, and anorectal functional results in female patients with rectal cancer. The robotic approach for rectal cancers in female patients could be not as critical as for male patients.
