Robotic subtotal gastrectomy with Hugo™ robotic-assisted surgery (RAS) system: first report on a case series
Abstract
Introduction Robotic-assisted surgery (RAS) has increasingly gained interest in gastric cancer treatment due to its enhanced precision and vision. Hugo™ RAS is a novel system designed to improve accessibility and reduce costs. However, its use in oncologic upper gastrointestinal procedures is still scarcely documented. Presentation of case We report four consecutive cases of subtotal gastrectomy with D2 lymphadenectomy performed using Hugo™ RAS at a single institution. Patients were selected following multidisciplinary evaluation and underwent full robotic procedures with standardized port placements. Intraoperative parameters, complications, and short-term oncologic outcomes were analyzed. Discussion All procedures were completed successfully without conversion or major complications. Median docking and console times were within acceptable limits, though longer than traditional laparoscopy due to system learning curve and intraoperative frozen section use. Lymphadenectomy was adequate in all D2 cases with R0 resection achieved. No blood transfusions were needed. Postoperative complications included delayed gastric emptying and a duodenal stump leak. The system proved safe, and the procedural setup did not require modifications from laparoscopic standards. Conclusion Subtotal gastrectomy with D2 lymphadenectomy using Hugo™ RAS is feasible and safe. The standardized setup and available instruments support oncologic adequacy without energy devices. Further studies are needed…
