Colorectal Surgery
Specialised surgical and non-surgical management of conditions affecting the colon, rectum and anus — including colorectal cancer, using robotic-assisted and laparoscopic techniques for better precision and faster recovery.
Da Vinci precision, where it matters most
For eligible colorectal cases — including colorectal cancer and rectal prolapse — Dr. Ratha offers robotic-assisted surgery using the da Vinci Surgical System at Gleneagles Hospital Kota Kinabalu, drawing on his fellowship training in Taiwan and South Korea.
- High-definition 3D visualisation for clearer anatomical views
- Tremor-filtered robotic arms for precise movement in the pelvis
- Smaller incisions, less trauma and scarring than open surgery
- Individualised treatment planning — robotic, laparoscopic or open, based on your case
