Abstract

Laparoscopic surgery for rectal cancer is technically challenging. Robotic and transanal TME (TaTME) are both novel approaches developed to provide better visualization and dissection. We aim to combine both approaches in a hybrid procedure and evaluate the feasibility as well as patient and oncological outcomes in this study. A review of a prospectively maintained database of patients who underwent a hybrid abdominal robotic approach with TaTME for rectal cancer between January 2016 and October 2018 was undertaken. Patient demographics, tumor characteristics and surgical outcomes were recorded and analyzed. A total of 69 patients (43 males, 26 females) received this hybrid approach. Their median age was 58 years (range 35–87) with a mean BMI of 24.3 kg/m2 (range 16.4–44.2). Median distance from anal verge was 5 cm (range 2–9). The patients had a median hospital length of stay of 7 days (range 5–28). Complication rate was 17.4% (12 patients) with 3 patients (4.3%) requiring a reoperation. TME quality was optimal with all of them either complete (81.2%) or almost complete (18.8%). 65 patients (94.2%) had an R0 resection with 4 patients (5.8%) with involved circumferential resection margins (≤ 1 mm). The median number of lymph nodes harvested was 20 (range 6–37). After a median follow-up of 27.7 months (range 7–42), local recurrence was identified in 2 patients (4%). Three patients (5.2%) had distant recurrence at the 3-year mark. Hybrid robotic abdominal dissection with transanal TME for rectal cancer appears to be feasible with comparable surgical outcomes to other traditional approaches.
