RESUMO
From November 2021 to February 2022, 15 patients underwent total abdominal mesorectal excision for rectal cancer using the da Vinci single port system. The clinical and pathological results were analyzed retrospectively. All surgeries were performed without conversion. The mean distance from the tumor to the anal verge was 10 cm (range, 2-15 cm). The mean operative time was 191 minutes, the median docking time was 4 minutes (range, 2-10 minutes), and the estimated blood loss was 20 mL (range, 20-50 mL). The mean number of lymph nodes harvested was 16.5, the mean distal resection margin was 3.52 cm, and all patients had circumferential and distal tumor-free resection margins. One patient had minor anastomotic leakage. The mean length of hospital stay was 5.8 ± 2.5 days. Abdominal total mesorectal excision using the da Vinci single port system for rectal cancer is technically feasible and safe, with acceptable pathological and short-term clinical outcomes.
RESUMO
PURPOSE: The Da Vinci SP robot system was recently introduced, but its safety and feasibility for rectal cancer compared with the currently used robot system have not been reported. METHODS: This was a single-centre retrospective study. Data from patients who underwent abdominal total mesorectal excision (TME) from October 2015 to October 2022 were analysed. After propensity score matching, the short-term outcomes were compared. RESULTS: A total of 56 patient data were analysed. Intersphincteric resection was more common in the SP group (7 cases (25%) vs. 0 case (0%), p = 0.001). The operation time was significantly shorter in SP (184 vs. 227.5 min, p < 0.0001), but the docking time was similar. The postoperative complications were similar. There were no differences in the postoperative pain score and length of hospital stay. CONCLUSION: The SP robotic system for abdominal TME has acceptable short-term and is safe and technically feasible.
