Colorectal Cancer Surgery

Laparoscopic and robotic surgery for colon and rectal cancers — sphincter-preserving, oncologically sound, functionally optimal.

Colorectal Cancer Surgery

Colorectal cancer is one of the commonest cancers in India and worldwide. Modern surgical techniques — laparoscopic colectomy, total mesorectal excision and robotic pelvic surgery — combined with multidisciplinary oncology care, offer excellent cure rates with preserved quality of life.

Frequently Asked Questions

What is colorectal cancer surgery?

It is the surgical removal of cancer from the colon or rectum along with the involved blood vessels and lymph nodes. The bowel is then rejoined.

Is laparoscopic colorectal surgery safe?

Yes — large randomised trials have shown laparoscopic colectomy and TME are as safe and oncologically equivalent to open surgery, with superior recovery.

What is robotic colorectal surgery?

Robotic surgery uses a console-based platform with 3D vision and wristed instruments, particularly useful for rectal surgery in the narrow male pelvis.

Will I need a stoma?

Most colon cancer operations do not need a stoma. For low rectal cancers, a temporary loop ileostomy is common; permanent stomas are rare with modern techniques.

What is ERAS?

ERAS (Enhanced Recovery After Surgery) is a standardised care pathway that speeds recovery — minimising fasting, using early feeding, early mobilisation and opioid-sparing analgesia.

How long is the hospital stay?

With ERAS, laparoscopic colectomy stay is 4-6 days; rectal resection is 5-8 days. Most patients return to work in 3-4 weeks.

Do I need chemotherapy after surgery?

Stage III colorectal cancer (node positive) requires 3-6 months of adjuvant chemotherapy. Stage II with high-risk features may also benefit.

What is CEA?

Carcinoembryonic antigen — a blood marker used to monitor colorectal cancer response and recurrence. It is not a screening test.

Is colorectal cancer curable?

Yes, at early stages. Stage I: 90%+ 5-year survival. Stage II: 80%. Stage III: 60-75% with surgery and chemotherapy. Stage IV is variable but sometimes curable.

How often should I have surveillance?

Clinical review and CEA every 3-6 months for 2 years, then 6-monthly. CT annually for 3-5 years. Colonoscopy at 1 year, then every 3-5 years if normal.
