GI cancer refers to cancers that affect the digestive system. This includes the oesophagus, stomach, small intestine, colon, rectum, liver, pancreas, and gallbladder. These cancers often develop slowly and may not show symptoms in the early stages.

Common warning signs include difficulty in swallowing, unexplained weight loss, persistent abdominal pain, blood in stools, chronic indigestion, or changes in bowel habits. Early consultation with a Gastroenterologist in Thrissur or GI cancer specialist can help detect the disease at a treatable stage.

  • Gastrectomy: In this type of surgery all of the portion of the stomach is removed. It is commonly used to treat stomach cancer (gastric). Complete gastrointestinal surgery (removal of the entire stomach) and partial gastrointestinal surgery (removal of a section of the stomach) are two types of gastrectomy.
  • Colectomy: A colectomy is the removal of part of the large intestine (colon). It is further classified as right hemicolectomy, left hemicolectomy, and sigmoid colectomy based on the exact spot of the cancer.
  • Hepatectomy: A part of the liver is removed during this procedure. It is frequently used to treat liver cancer (hepatocellular carcinoma) or metastases from other gastrointestinal cancers.
  • Pancreaticoduodenectomy (Whipple procedure): This is a very complex surgery done to treat pancreatic cancer located in the pancreatic head. It includes the removal of the pancreatic head, a section of the small intestine (duodenum), the gallbladder, and, in certain cases, a portion of the stomach.

Accurate diagnosis is very important to treat GI cancer effectively. Dr. Arun S. Nair follows a step-by-step and advanced approach to make sure the disease is correctly identified. The process usually starts with a detailed medical history and physical examination. Dr. Nair carefully reviews symptoms like difficulty in swallowing, stomach pain, changes in bowel habits, blood in stools, or unexplained weight loss.

Next, investigations and tests are performed:

  • Endoscopy and Colonoscopy: These tests allow doctors to look inside the oesophagus, stomach, and intestines to detect abnormal growths or tumors.
  • Imaging Tests: CT scans, MRI, and sometimes PET scans help see the exact location, size, and spread of the cancer.
  • Biopsy: A small tissue sample is taken from the suspected area to confirm cancer under a microscope.
  • Blood Tests and Tumor Markers: These tests give additional information about the type and activity of the cancer.

As the Best GI Surgeon in Thrissur, Dr. Arun S. Nair ensures that all test results are explained clearly to patients and their families. He focuses on early detection, which allows treatment to start sooner. Early diagnosis often means less invasive surgery, faster recovery, and better chances of a complete cure.

GI cancer treatment usually involves a combination of surgery, chemotherapy, radiation therapy, and targeted therapy. Surgery remains the cornerstone for most GI cancers.

Dr. Arun S. Nair specialises in:

  • Minimally invasive laparoscopic surgery
  • Robotic-assisted GI cancer surgery
  • Open surgery for advanced or complex cases

As a leading Laparoscopic Surgeon in Thrissur, he focuses on smaller incisions, less pain, and faster recovery. As an experienced Robotic Surgeon in Thrissur, he uses advanced robotic systems for higher precision and better cancer clearance.

Each treatment plan is customised based on cancer stage, patient health, and personal needs.

  • Intention to treat – For early-stage GI cancer that has not spread to other body parts, surgery is the primary choice of treatment. Surgical removal of the tumor may result in an effective treatment.
  • Local Control – Surgery may remove the cancerous tissue as well as neighboring lymph nodes, lowering the chance of recurrence and preventing the cancer from spreading to other tissues.
  • Prognosis Improvement – By removing the source of cancer growth, surgical excision of the tumor can greatly improve the patient’s long-term prognosis for various GI cancers.
  • Diagnostic Staging – Surgery is often done for diagnosis, allowing for proper cancer staging and determining the extent of its spread in the body. This knowledge helps with future treatment decisions.
  • Minimally Invasive Techniques – Many GI cancer operations may be done using less invasive methods like laparoscopic or robotic surgery. In comparison to traditional open surgery, these procedures result in smaller incisions, less pain, less hospitalizations, as well as quicker recuperation times.
