Staging first, decisions second
Colonoscopy, biopsy, CT and a high-resolution pelvic MRI for rectal tumours. Nothing is planned until the stage is known.

Laparoscopic & robotic colorectal surgery
Keyhole and robotic surgery for colon and rectal cancer, planned so that recovery is faster without a single compromise on the cancer margin.

At a glance
- Approach
- Robotic or laparoscopic, decided by anatomy and staging
- Anaesthesia
- General
- Hospital stay
- Typically 4–7 days
- Wounds
- Several small ports; a short extraction incision
- Back to desk work
- Commonly 3–4 weeks
Who this is for
- Biopsy-proven colon or rectal cancer needing resection
- Low or mid rectal tumours where a precise pelvic dissection matters
- Large polyps that cannot be removed endoscopically
- Selected cases after chemotherapy or radiotherapy
- Patients who want to know whether keyhole surgery is safe in their specific case
Cancer surgery is judged on two things: whether the disease was removed completely, and what your life looks like afterwards. Robotic instruments articulate inside the narrow pelvis where human wrists cannot, which is exactly where rectal cancer surgery is won or lost. Keyhole access is chosen because recovery matters — never as a reason to accept a poorer margin.
What actually happens, step by step.
02
Multidisciplinary planning
Your case is discussed with oncology, radiology and pathology. Some rectal cancers do better with chemoradiotherapy before surgery, not straight to theatre.
03
The operation
Total mesorectal excision for rectal cancer, complete mesocolic excision with central vascular ligation for colon cancer. The specimen quality is the outcome.
04
Enhanced recovery
Early feeding, early mobilisation, opioid-sparing pain control. Getting you upright on day one is treatment, not encouragement.
05
Histopathology and next steps
The final report determines whether chemotherapy is needed. You are told the margin status and node count in plain language.
Recovery, honestly
- Walking on the day after surgery; fluids and light diet resumed early.
- Discharge once eating, mobile and pain is controlled orally.
- Bowel habit is often unsettled for weeks to months after rectal surgery — this is expected and managed.
- Surveillance scans, colonoscopy and CEA follow a written schedule you are given on discharge.
Risks and limits
- Anastomotic leak — the complication that governs how the whole operation is planned, and why a temporary stoma is sometimes the safer choice.
- Bleeding, infection, and the general risks of major abdominal surgery.
- Changes to bowel, urinary or sexual function, most relevant in low rectal surgery — discussed before, not after.
- Conversion from keyhole to open surgery where safety demands it. That is a judgement, not a failure.

Bring these to your appointment
Questions worth asking any surgeon — including me.
- 01What is my exact stage, and did an MDT review it?
- 02Is a keyhole or robotic approach appropriate in my case, and why?
- 03What is the plan if a leak occurs?
- 04Who performs the operation from start to finish?
Common questions
Is robotic surgery better than laparoscopic surgery?
It is better suited to some situations, particularly a deep, narrow pelvis in rectal cancer, where articulated instruments allow finer dissection. For many colon operations laparoscopy is equally good. The anatomy decides, not the marketing.
How long is the hospital stay after colorectal cancer surgery?
Most patients go home in four to seven days with an enhanced-recovery pathway — earlier feeding, earlier walking, less opioid. Longer if a complication arises.
Will I need chemotherapy after surgery?
It depends on the final histopathology — nodal involvement and other risk features. That decision is made with the medical oncologist once the report is back, not promised beforehand.
Next step
Send your reports first. The appointment then starts further ahead.
Colonoscopy report, biopsy, scans and any plan you have already been given. A written second opinion costs nothing and carries no obligation to change doctors.
