Initial experience of single-incision robotic surgery for distal gastrectomy with da Vinci Xi platform.

Background: The aim of this study was to describe technical considerations and short-term outcomes from the first reported single-incision robotic operation for distal gastrectomy with the use of da Vinci Xi surgical system. Methods: A 71-year-old patient with a body-mass index of 22.4 kg/m² was treated for a gastrointestinal stromal tumor(GIST) in the posterior wall of the gastric antrum by single-incision robot-assisted distal gastrectomy with the da Vinci Xi robotic system on September 17, 2022 in Shanghai General Hospital. Results: The single-incision da Vinci Xi robot-assisted distal gastrectomy was successfully performed with intraperitoneal Billroth II anastomosis. The console time among the operation was 100 min with 10 ml of intraoperative blood loss. The patient was put on a liquid diet the next day after surgery and discharged on postoperative day 4. During the postoperative period, no severe adverse events occurred. The final pathology revealed a low-risk gastrointestinal stromal tumor (GIST) with a size of 5.0 × 3.5 × 2.5 cm. Conclusion: Single-incision da Vinci Xi robot-assisted distal gastrectomy was a safe and feasible surgical method for patients with gastric tumor. The study filled in the corresponding research gaps and provided a basis for subsequent research. To verify its superior operative outcomes, further clinical trials are needed. [ABSTRACT FROM AUTHOR]
