Purpose:
Reduced-port surgery has been utilized in gastric cancer surgery but is not predominantly used due to its high technical difficulty. A new single-port surgical robot named da Vinci™ SP System (DVSP) was launched and eventually approved for clinical use in Japan in November 2022. We initiated robotic gastrectomy for gastric cancer using DVSP in March 2023. Here, we report our initial experiences and assessments of the feasibility and safety of robotic gastrectomy for gastric cancer using DVSP.
Methods:
This single-center retrospective study included 20 patients with gastric cancer who underwent robotic gastrectomy with DVSP from March 2023 to April 2024. The primary endpoint was the postoperative complication rate within 30 days postoperatively. Secondary endpoints were surgical outcomes, including intraoperative adverse events, operative time, blood loss, and the number of dissected nodes.
Results:
Of the 20 patients, 6 (30.0%) were male. The median age was 74 years. Tumors in the middle to lower stomach were observed in 20 patients (100.0%), including 18 (90.0%) and 2 (10.0%) with clinical stages I and II diseases, respectively. All patients underwent distal gastrectomy. The postoperative complications of Clavien-Dindo grade ≥ II occurred in 3 (15%) patients. Intraoperative adverse events, including conversion to other approaches, were not observed. All patients underwent R0 resection. The median operative and console times were 289 and 240 min, respectively. The median blood loss was 11 mL with 50 dissected nodes.
Conclusion:
This study revealed the safe performance of robotic distal gastrectomy with standard lymphadenectomy for clinical stage I/II gastric cancer using DVSP.
