What the evidence shows
Across colorectal, gynaecological and urological oncology, large series and randomised trials report morbidity rates similar to or lower than conventional approaches, with reduced transfusion requirement. Device-related complications are uncommon and the platform has multiple mechanical safety interlocks and instant instrument release.
Risks that apply to any cancer operation
Every abdominal or pelvic cancer resection carries risk that must be weighed against the risk of leaving the tumour untreated.
- Bleeding and the possibility of transfusion
- Infection, including wound and chest infection
- Anastomotic leak after bowel or stomach resection
- Injury to ureter, bladder, bowel, nerves or vessels
- Blood clots, and cardiac or respiratory events under anaesthesia
- Conversion to open surgery
How risk is reduced
Preoperative optimisation of anaemia, glycaemic control and nutrition; multidisciplinary tumour board planning; ERAS protocols; thromboprophylaxis; and structured follow-up. Each patient receives an individualised statement of their own risk during consent rather than a general figure.
Common questions
- What happens if the system malfunctions during surgery?
- Instruments can be undocked within seconds and the operation continued laparoscopically or open. Teams rehearse this scenario.
- Is robotic surgery safe for elderly patients?
- Age alone is not a barrier. Reduced blood loss and earlier mobilisation are often advantageous, but fitness for prolonged anaesthesia and head-down positioning is assessed individually.
