Robot-assisted surgery is a minimally invasive approach performed through small incisions.
Using a magnified three-dimensional view and articulated instruments, it allows precise dissection
and may be particularly useful in technically demanding pelvic surgery for rectal cancer.
Overview
In Japan, laparoscopic surgery has become a standard minimally invasive approach for colorectal surgery.
Robot-assisted surgery has been introduced to further improve precision and control in selected procedures.
Laparoscopic techniques have been widely used for many years, and robotic platforms were developed
to extend the capabilities of minimally invasive surgery.
What is the da Vinci Surgical System?
The da Vinci Surgical System is a robotic surgical platform used to support complex minimally invasive procedures.
It provides the surgeon with a high-definition three-dimensional view and wristed instruments that allow precise movements in confined spaces.
-
Three-dimensional visualisation:
A magnified operative view supports detailed dissection in the abdomen and pelvis. -
Instrument control:
Robotic instruments allow fine movements and stable handling in narrow operative fields. -
Minimally invasive access:
Small incisions may reduce postoperative pain and support recovery compared with open surgery in selected patients.
Whether robot-assisted surgery is appropriate depends on tumour location, stage, anatomy, and overall clinical condition.
Why robot-assisted surgery is useful for rectal cancer
Robot-assisted surgery is particularly useful for complex pelvic procedures,
where the operative field is narrow and precise dissection is required.
- Ultra-low anterior resection for rectal cancer
- Intersphincteric resection for sphincter preservation in selected cases
- Lateral pelvic lymph node dissection in selected patients
The aim is to achieve oncologically appropriate resection while preserving function and quality of life where possible.
da Vinci Xi at our hospital
Kishiwada Tokushukai Hospital introduced the da Vinci Xi system in 2021.
Since then, robot-assisted surgery has been applied to selected cases of
colon cancer and rectal cancer.
Surgeons, nurses, and clinical engineers work together to support safe implementation,
technical development, and ongoing training in minimally invasive colorectal surgery.
Appointment
Appointments are required in principle. A referral letter from another medical institution is recommended but not mandatory.
