Surgery is usually the primary treatment for early-stage colon cancer. The type of surgery used depends on the stage (extent) of cancer, where it is found in the colon, and the purpose of the surgery. Any type of colon surgery should be performed on an empty and clean colon. You will need a special diet before the operation. Read this blog to know more about colorectal surgery and how to prepare for it.

What happens during a colorectal surgery?

Colorectal is performed by a physician (always go for the best laparoscopic surgeon in Kolkata) experienced in the procedure. This surgery takes approximately 30-60 minutes. The anesthetic medicines will be given into a vein to make you feel relaxed and sleepy. You will be asked to lie on your left side on the exam table. During a colonoscopy, the doctor uses a colonoscope, a long, flexible tubular instrument about 1/2 inches in diameter. This instrument transmits an image of the lining of the colon so the doctor can examine it for abnormalities. The colonoscope is inserted through the rectum and advanced to the other end of the large intestine.

During a colonoscopy, if the doctor sees something that is abnormal, small amounts of tissue may be taken for analysis (called a biopsy) and abnormal growth or polyps can be identified and removed. In most cases, colorectal allows accurate diagnosis and treatment without the need for a major operation. However, contact the best surgeon near you to get the suitable treatment done.


Colon cancer symptoms include:

  • A change in bowel habits (usually constipation)
  • Blood in the stool, a feeling that the bowel is not emptying, and persistent cramps or gas.
  • Weight loss, stool as thin as a pencil
  • Weakness and fatigue

However, when symptoms do occur, the cancer is usually quite advanced.

Things to do before undergoing a colorectal

Before a colonoscopy, tell your doctor about any specific medical conditions you have, including:

  • Pregnancy
  • Lung diseases
  • Heart disease
  • Allergies to any medication.

If you have diabetes or are taking medicines, these can affect blood clotting. Inform your surgeon about all the medications you have been taking before finalizing the day of your laparoscopy surgery in Kolkata. However, never stop taking medicine without consulting your doctor first.

Even if you have never had a colorectal before, you may have heard of them. Preparing for the surgery involves cleansing your intestines with a laxative drink the night before. Laxative helps to cleanse the gut a few hours before the procedure. You will have to stay in the bathroom for a few hours and probably experience side effects like diarrhea. However, doctors often recommend this cleansing process before performing a laparoscopic surgery.
