Purpose/Background: The purpose of this study was to analyse the conversion rate to open abdominal surgery and sphincter preservation in patients with low rectal tumors during laparoscopic transanal total mesorectal excision (TaTME) procedures performed at a high-volume Turkey referral center.

Methods/Interventions: A multicentre observational study was conducted using a prospective database, including patients diagnosed with rectal cancer below the peritoneal refection who underwent minimally invasive elective surgery. Exclusion criteria were (1) sphincter and/or puborectalis invasion; (2) multi-visceral resections; (3) palliative surgeries.
All consecutive TaTME performed for mid-to-low rectal cancer , independently if treated with a primary anastomosis (with/without a diverting ostomy) or an end stoma. All procedures were performed using a standardized approach by the same surgical team.

Results/Outcomes: Between January 2017 and October 2024, 51 males and 24 females with median age of 64 (IQR 24–72) years and BMI 29 (IQR 25–33) kg/m2 underwent 2-team taTME for tumors located a median 5.4 (IQR 3.4–7.0) cm from the AV. Neoadjuvant radiotherapy was completed in 80%. Intersphincteric resection was performed in 40% and all patients were diverted. Intraoperative complications occurred in 2,6% including 1 organ injuries and 1 vascular arc rupture. Conversion from the abdominal region to open was performed in 2 patients. Abdominoperineal resection was performed in 2 patients. sphincter preservation rate is 97%.
Anastomotic complications were reported in 6% including .

Conclusion/Discussion: When performed at expert centers, 2-team taTME in patients with low rectal tumors is safe with low conversion rates and high sphincter preservation rate. Mid-term results will further evaluate oncologic and functional outcomes
