Colorectal Cancer Surgery: What Patients Should Know

Colorectal cancer — which affects the colon or rectum — is one of the most common yet treatable cancers when detected early. Surgery plays a vital role in curing and controlling this condition. At Iswarya Hospital, our expert oncologists and surgical specialists use advanced minimally invasive and robotic techniques to ensure safe, effective outcomes.

Understanding Colorectal Cancer

Colorectal cancer begins when abnormal cells grow uncontrollably in the lining of the colon or rectum. Depending on the size, location, and spread of the tumour, doctors determine the right treatment — and in most cases, surgery is the cornerstone.

Every patient undergoes a detailed diagnostic process including colonoscopy, biopsy, CT/MRI scans, and genetic tests. This helps our oncologists create a personalised surgical plan.

Types of Colorectal Cancer Surgeries

Polypectomy and Local Excision In the early stages, when the tumour is confined to a small polyp, it can be removed during a colonoscopy. This is minimally invasive and does not require external incisions.

Colectomy (Colon Resection) This is the most common surgery for colon cancer. The surgeon removes the affected part of the colon along with nearby lymph nodes and reconnects the healthy portions. Iswarya Hospital specialises in laparoscopic and robotic-assisted colectomies, which reduce post-surgical pain and hospital stay.

Proctectomy (Rectal Resection) For rectal cancers, the affected section of the rectum is removed. Our colorectal surgeons ensure sphincter preservation whenever possible, allowing patients to maintain normal bowel control.

Robotic-Assisted Surgery Robotic technology allows surgeons to operate with unmatched precision, even in difficult-to-reach areas. Led by Prof. Dr. S. Rajasundaram, our robotic-assisted cancer surgeries offer greater precision, less pain, smaller scars, and quicker recovery.

How Surgery Is Planned at Iswarya Hospital

Every case follows a multidisciplinary approach:

• Pre-surgical evaluation: Physical assessment, lab work, and imaging
• Tumour board discussion: Oncologists, surgeons, radiologists, and pathologists decide the best treatment path
• Patient counselling: Our care coordinators explain the entire process to reduce anxiety

Recovery After Surgery

• Hospital Stay: 4–7 days for open surgery; 2–4 days for laparoscopic/robotic surgery
• Pain and Wound Care: Well managed with medication; wound-care instructions provided before discharge
• Dietary Changes: Initially soft/liquid diet; gradually returning to normal food
• Follow-Up: Regular visits including physical checks, imaging, and colonoscopy

Why Choose Iswarya Hospital?

At Iswarya Hospital, we believe cancer care is not just about removing tumours — it's about restoring health, confidence, and hope.

FAQs

How long does it take to recover from colorectal cancer surgery? Most patients resume normal activities within 4–6 weeks. Robotic and laparoscopic surgeries typically allow faster recovery.

Will I need a colostomy bag after surgery? Not always. It depends on the tumour's location and extent. Our surgeons strive to avoid permanent colostomies wherever possible.

Is robotic colorectal surgery better than open surgery? Robotic surgery offers greater precision, less pain, smaller scars, and quicker recovery — all available at Iswarya Hospital's oncology unit.

Can colorectal cancer return after surgery? There's a possibility, which is why regular follow-ups and screenings are crucial. Our oncology team designs a long-term surveillance plan for each patient.

How soon after surgery can I start chemotherapy? Usually within 4–6 weeks post-surgery, once the patient has adequately healed. Treatment plans are customised after reviewing recovery progress.
