Robotic subtotal gastrectomy with Hugo™ robotic-assisted surgery (RAS) system: first report on a case series

Area of Science:

• Surgical Oncology
• Gastrointestinal Surgery
• Robotic Surgery

Background:

• Robotic-assisted surgery (RAS) offers enhanced precision for gastric cancer treatment.
• The Hugo™ RAS system aims to improve accessibility and reduce costs in surgery.
• Limited documentation exists on Hugo™ RAS for oncologic upper gastrointestinal procedures.

Purpose of the Study:

• To evaluate the feasibility and safety of subtotal gastrectomy with D2 lymphadenectomy using the Hugo™ RAS system.
• To analyze intraoperative parameters, complications, and short-term oncologic outcomes.
• To assess the adequacy of oncologic resection and lymphadenectomy in robotic-assisted gastric cancer surgery.

Main Methods:

• Four consecutive cases of subtotal gastrectomy with D2 lymphadenectomy were performed using Hugo™ RAS.
• Standardized port placements and full robotic procedures were employed.
• Intraoperative data, complications, and oncologic outcomes were meticulously analyzed.

Main Results:

• All procedures were successfully completed robotically without conversion or major complications.
• Adequate D2 lymphadenectomy and R0 resection were achieved in all cases.
• Postoperative complications included delayed gastric emptying and a duodenal stump leak; the system demonstrated safety.

Conclusions:

• Subtotal gastrectomy with D2 lymphadenectomy using Hugo™ RAS is a feasible and safe oncologic procedure.
• The system's setup and instruments support oncologic adequacy.
• Further studies are required to validate long-term results and compare Hugo™ RAS with conventional methods.
