International Registry for Robot-Assisted Minimally Invasive Gastrectomy RAMIG in Gastric Cancer Patients

What this Trial Is About

Gastric cancer is a leading cause of cancer-related deaths globally. For patients with resectable gastric cancer, surgery to remove the stomach gastrectomy combined with chemotherapy improves survival. Minimally invasive gastrectomy MIG is increasingly used to reduce surgical trauma while maintaining effective cancer treatment. However, MIG has technical challenges, such as limited instrument movement and depth perception. Robot-Assisted Minimally Invasive Gastrectomy RAMIG may overcome these challenges by providing enhanced dexterity, 3D visualization, and precise control to improve surgical accuracy. This observational study aims to create an international registry to monitor RAMIG techniques and outcomes worldwide and to understand the learning curve for surgeons adopting RAMIG. The study collects data both prospectively and retrospectively from patients undergoing RAMIG for gastric cancer across multiple continents through the Upper Gastrointestinal International Robotic Association UGIRA. The registry gathers detailed information on surgical techniques, postoperative outcomes, and complications using standardized definitions. This approach enables consistent comparison of results globally. The study also supports surgeons in training by evaluating their progress during the learning phase of RAMIG, aiming to reduce complications and improve patient safety during this period. Participants in this study are patients with gastric cancer scheduled for RAMIG. Data collected include operation time, blood loss, complications during surgery, conversion rates to open surgery, completeness of tumor removal, and number of lymph nodes removed. Postoperative adverse events are tracked up to 90 days after surgery. By collecting uniform data through an online system, the study aims to provide insights into surgical quality and outcomes while monitoring the learning curve for this advanced robotic technique. The study will continue through 2031, supporting international collaboration and quality improvement in robotic gastrectomy.
