Diagnostic Upper GI Endoscopy

Also known as Esophagogastroduodenoscopy (EGD) involves the insertion of an endoscope through the mouth for internal examination. It is commonly used to evaluate symptoms such as persistent heartburn, difficulty swallowing, nausea, vomiting, diarrhea or unexplained weight 

Nutritional Assessment and Counseling

Recognizing the critical role of diet in gastrointestinal health, our registered dieticians provide comprehensive nutritional assessments for our patients. Nutritional assessment and counseling are essential components of our gastroenterology care. Our dieticians help in identifying malnutrition, planning appropriate dietary interventions, managing symptoms, supporting treatment and recovery, preventing complications and monitoring treatment response. By addressing nutritional needs, our dieticians optimize patient outcomes and improve the overall quality of life for individuals with gastrointestinal disorders. 

Therapeutic EUS

Therapeutic endoscopic ultrasound (EUS) is a specialized procedure used in gastroenterology for therapeutic purposes. It combines endoscopy with ultrasound imaging to visualize and guide interventions within the gastrointestinal tract and adjacent organs. Therapeutic EUS enables the drainage of fluid collections, placement of drainage stents, injection of therapeutic agents, delivery of radiofrequency ablation for tumor treatment, and sampling of deep tissue lesions. It provides a minimally invasive approach for targeted interventions, aiding in the management of pancreaticobiliary disorders, gastrointestinal tumors, and other complex gastrointestinal conditions. We can also diagnose and treat conditions such as draining cysts, celiac plexus block for pain management in chronic pancreatitis, pancreatic cancer and place stents in the bile or pancreatic ducts, and EUS-guided gastrojejunostomy. 

Therapeutic Colonoscopy

Therapeutic endoscopy refers to a set of minimally invasive procedures performed using a colonoscope to treat various gastrointestinal conditions. It involves interventions such as removing polyps or tumors, dilating strictures, placing stents, treating bleeding lesions, and delivering targeted therapies. Therapeutic endoscopy offers a less invasive alternative to surgery, allowing for precise and effective treatment while minimizing patient discomfort and recovery time. It plays a crucial role in managing a wide range of gastrointestinal disorders and improving patient outcomes.

Therapeutic Endoscopy

This covers a range of procedures, such as polypectomy (removal of polyps), endoscopic dilation (stretching of a narrowed area), variceal band ligation, hemostasis (stopping bleeding) for ulcer bleeds, esophageal and duodenal stenting, helping treatment of many GI disorders without the need for invasive surgery.


FibroScan is a valuable tool for assessing liver fibrosis, typically used in conjunction with other clinical and laboratory evaluations to provide a comprehensive assessment of liver health. The results of FibroScan, along with additional tests and patient history, help gastroenterologists and hepatologists in diagnosing liver diseases, monitoring disease progression, and determining appropriate treatment strategies.
The FibroScan procedure involves the use of a specialized ultrasound probe to measure liver stiffness. The patient lies on a table, and the probe is placed on the skin surface over the liver. The probe sends a vibration through the liver, and the resulting shear wave speed is measured. The liver stiffness is then calculated based on the speed of the shear waves, which correlates with the degree of fibrosis.
It's primarily used to assess the presence and extent of liver fibrosis, a condition often associated with hepatitis, alcoholic liver disease, fatty liver, and chronic liver diseases (cirrhosis of the liver).
It is a non-invasive, quick, convenient, and repeatable procedure that reduces the need for Liver Biopsy. 

Endoscopic Ultrasound (EUS)

This diagnostic procedure combines endoscopy and ultrasound to obtain detailed images and information about the digestive tract and the surrounding tissue and organs. It involves the insertion of an endoscope equipped with an ultrasound probe through the mouth or rectum, providing high-resolution images of the digestive tract wall layers and surrounding structures. It is used for various indications, including diagnosing bile duct stones, bile duct strictures, chronic pancreatitis, evaluating gastrointestinal cancers, evaluating pancreatic lesions, guiding fine-needle aspirations for tissue sampling, and assisting in the placement of drainage devices. It is also used to obtain tissue biopsy from the abdomen and mediastinum(chest) for diagnosis (histological examination). 

ERCP (Endoscopic Retrograde Cholangiopancreatography)

ERCP combines endoscopy with fluoroscopy to diagnose and treat disorders of the bile ducts and pancreas including bile duct stones, strictures (Narrowing), leaks, and cancer. It involves the insertion of an endoscope through the mouth, passing through the stomach and duodenum to access the bile ducts and pancreatic ducts. ERCP is used to remove obstructions and perform interventions such as stent placement or tissue sampling in cases of biliary or pancreatic diseases.

Capsule Endoscopy

It is a non-invasive procedure that involves swallowing a small capsule containing a camera to capture images of your digestive tract, particularly the small intestine. It's typically used to diagnose lesions located in the small intestine that are not accessible to conventional endoscopy. This procedure is beneficial because it does not require surgery or anesthesia, and it is a less invasive way to diagnose diseases and abnormalities of the digestive tract. Furthermore, the images captured by the camera allow for a more accurate diagnosis.

Diagnostic Colonoscopy

It is primarily used for colorectal examination. It involves the insertion of an endoscope through the rectum to visualize the entire colon and rectum. It allows direct visualization and sampling of tissues (biopsies) for further analysis. This involves examining the large intestine for abnormalities like hemorrhoids (Piles), anal fissures, polyps, inflammatory bowel diseases (Ulcerative colitis, and Crohn’s), intestinal tuberculosis, cancer, etc. A colonoscopy also allows for the biopsy or removal of suspicious lesions and is a crucial tool in colon cancer screening and prevention.

hen I visit a Gastroenterologist for the first time what should I expect?

Your doctor will study your files along with previous test reports to evaluate and diagnose your problem. If required the doctor may prescribe further diagnostic and blood tests for appropriate diagnosis and a plan for your medical treatment accordingly.

What problems can a gastroenterologist treat?

A gastroenterologist treats, diagnoses, and manages conditions of the gastrointestinal system as well as digestive organs. This includes everything from the esophagus and stomach to the liver, pancreas, and gallbladder.

What is fatty liver? What leads to this problem?

fatty liver is the condition of accumulation of fat in liver. It can lead to inflammation in the liver and eventually lead to a variety of health problems. The Fatty lever is generally associated with many lifestyle factors. The most common cause is obesity, as well as excess alcohol consumption, diabetes, and high cholesterol. An unhealthy diet may also play a role in the development of fatty liver, as well as certain medications and certain medical conditions.

Why do I need to see a Gastroenterologist?

If you have complaints related to the digestive system such as frequent abdominal pain, nausea, diarrhea, constipation, or heartburn for a prolonged time you might need to visit a Gastroenterologist. Also, If you are 45 years or older and have a family history of GI cancer it is advisable to seek frequent checkups from a gastroenterologist.

How can I prevent colon cancer?

To improve your health and reduce your risk of colon cancer, you can make several easy lifestyle changes, such as limiting alcohol consumption, quitting smoking, eating a balanced diet rich in fruits and vegetables, exercising regularly, and maintaining a healthy weight.

What are the first signs of liver damage from alcohol?

Alcohol abuse is linked to many health problems, including liver damage. The signs of liver damage from alcohol include elevated liver enzymes, jaundice, ascites, and swelling in the abdomen.

In more advanced stages of liver damage from alcohol, the liver can become significantly enlarged and tender. This is known as hepatomegaly. Additionally, fibrosis, or scarring of the liver, can occur and lead to cirrhosis. Cirrhosis is a condition in which the liver is permanently damaged and can no longer function properly.

What is the difference between endoscopy and colonoscopy?

A colonoscopy is a procedure that examines the entire large intestine from the rectum to the cecum. During the procedure, a doctor will look for any abnormalities, such as polyps, ulcers, or tumors. The procedure can also be used to diagnose conditions such as inflammatory bowel disease or diverticulitis.

An endoscopy, on the other hand, is a procedure that examines the entire digestive tract, including the stomach, small intestine, and large intestine. Unlike a colonoscopy, endoscopies are often used to diagnose or treat conditions of the stomach, such as ulcers, blockages, or cancers. Endoscopies can also be used to identify any problems in the small intestine, including Crohn's disease and celiac disease.
