In this group, robotic distal gastrectomy is performed with assistant-controlled laparoscopic instrumentation. The assistant conducts vascular clipping using articulating Hemolock clip appliers (Livsmed) or Challenger® clip appliers (B.Braun). For gastrointestinal anastomosis, the assistant operates an Echelon stapling system (Johnson \& Johnson) via the assistant port. The surgeon controls the robotic console for all other surgical steps. This method utilizes a hybrid approach, combining robotic precision with laparoscopic efficiency.

In this group, all surgical steps, including vascular clipping and anastomosis, are performed using the robotic system. The surgeon utilizes the Da Vinci Xi system and switches robotic instruments as needed. Vascular clipping is performed with robotic Hemolock or Hemoclip appliers, and anastomosis is conducted using the SureForm robotic stapler. This fully robotic technique eliminates laparoscopic assistance and utilizes only robotic arms for the entire procedure. Both groups follow the same postoperative care protocols, including standardized pain management and recovery assessments.
