[Simultaneous Robotic Surgery for Synchronous Multiple Cancers with Gastric Cancers-Three Case Reports]

Area of Science:

• Surgical Oncology
• Minimally Invasive Surgery
• Gastrointestinal Oncology

Background:

• Synchronous gastric cancer (GC) occurring with other malignancies is uncommon.
• Managing multiple primary cancers necessitates careful surgical planning and execution.

Purpose of the Study:

• To evaluate the feasibility and outcomes of simultaneous robotic surgery for gastric cancer in patients with concurrent colorectal or renal cancers.
• To assess the safety, efficiency, and benefits of combined robotic procedures.

Main Methods:

• Three cases involving simultaneous robotic surgery were performed: two with colorectal cancer and one with renal cancer.
• Procedures included various combinations of robotic resections such as anterior resection, hemicolectomy, nephrectomy, and gastrectomy with lymph node dissection (LND).

Main Results:

• All simultaneous robotic procedures were performed safely, with minimal to moderate blood loss (0-447 mL).
• Operation times ranged from 600 to 926 minutes.
• The approach successfully addressed multiple synchronous cancers in a single operative session.

Conclusions:

• Simultaneous robotic surgery is a viable and beneficial option for patients diagnosed with synchronous gastric cancer and other malignancies.
• This approach offers advantages in preventing tumor progression during waiting periods and avoiding reoperation adhesions.
