Colorectal Cancer Surgery

Colorectal Cancer Surgery in Rangapani, Siliguri

Colorectal Cancer Surgery involves removing cancerous growths from the colon or rectum to prevent further spread and reduce the risk of recurrence. Surgical options range from minor Polypectomies to major Resections such as Colectomies or Colostomies.

At Manipal Hospital, Colorectal Cancer Surgery in Rangapani, Siliguri, is performed by experienced colorectal surgical oncologists using advanced laparoscopic and robotic techniques. They focus on early diagnosis, precise tumour removal, and enhanced recovery outcomes.

Why is Colorectal Cancer Surgery performed?

Colon and Rectal Cancer Surgery in Rangapani, Siliguri, is performed to:

• Remove localised tumours or polyps

• Prevent cancer from spreading to lymph nodes or other organs

• Relieve symptoms such as bleeding, obstruction, or pain

Conditions treated using this surgery include colon cancer (all segments), rectal cancer, familial adenomatous polyposis (FAP), and inflammatory bowel disease with dysplasia.

What to expect before Colorectal Cancer Surgery?

Before Colorectal Cancer Surgery in Rangapani, Siliguri, patients undergo:

• Diagnostic tests, including Colonoscopy, Biopsy, CT/MRI scans to assess tumour spread, blood tests, and cardiac evaluations.

• Preoperative preparation includes bowel cleansing, nutritional counselling, medication adjustments, and anaesthesia consultation.

• Patients are also educated about the procedure, the expected recovery period, and stoma care, if required.

What to expect during Colorectal Cancer Surgery?

Colon and Rectal Cancer Surgery in Rangapani, Siliguri, is performed using open, laparoscopic, or robotic-assisted techniques. The choice of technique and surgical approach depends on the tumour’s location, stage, and the patient’s overall condition. The surgeon selects the most appropriate method to ensure safe and effective cancer removal. 

Common types of procedures include:

1. Polypectomy or Local Excision

These are typically used for early-stage tumours detected during Colonoscopy. The surgeon inserts a thin, flexible tube (endoscope) with a camera to locate polyps. A wire loop (snare) and electrocautery are used to remove the growths, which are then sent to a lab for analysis.

2. Partial Colectomy

This procedure is also known as Segmental Resection, which involves removing the cancerous portion of the large intestine along with nearby blood vessels and lymph nodes. The remaining healthy ends are reconnected using staples or sutures.

3. Total Colectomy

This is used for extensive disease or genetic conditions like familial adenomatous polyposis (FAP) or ulcerative colitis. The procedure involves removing the entire colon through an abdominal incision. If feasible, the surgeon reconnects the small intestine to the rectum.

4. Ileostomy or Colostomy

When reconnection of the bowel is not possible, the surgeon creates a stoma (opening) in the abdominal wall. Waste passes through this opening into a bag, which may be temporary or permanent, depending on the healing process and the extent of the disease.

General Procedure for Colorectal Cancer Surgery

The procedure is typically performed under general anaesthesia and follows these general steps:

• The surgeon makes abdominal incisions using either open surgery or minimally invasive techniques.

• The affected portion of the bowel and the nearby lymph nodes are carefully removed, ensuring clear margins.

• The surgeon reconnects the healthy bowel ends or creates a stoma (if reconnection is not possible).

• The surgical site is closed using sutures or staples, and sterile dressings are applied.

What to expect after Colorectal Cancer Surgery?

After Colorectal Cancer Surgery in Rangapani, Siliguri, patients are closely monitored in the recovery area. Doctors focus on healing, pain control, bowel function, and checking for complications. Nutrition is reintroduced slowly, starting with liquids and moving to soft foods. Physiotherapists help patients regain movement and prevent stiffness.

If a stoma is created, trained nurses teach the patient how to care for it. Most patients start walking within 1–2 days and may go home in 5–7 days, depending on their recovery. Follow-up visits include checking the wound, managing the stoma if present, and monitoring for cancer recurrence.

What are the benefits and risks?
