The Gastroenterology Department at Catskill Regional Medical Group – led by Kasim Kazbay, M.D. – has physicians and healthcare providers who are trained to investigate the digestive system and diagnose its disorders.

Our gastroenterologists treat diseases affecting the gastrointestinal tract, which include the organs from mouth into anus, along the alimentary canal – such as the esophagus, stomach, small intestine, colon, rectum, pancreas, gallbladder, bile ducts, and the liver.

Our specialists are trained medical diagnosticians with the knowledge base to treat:

  • Acid Reflux
  • Colon Cancer
  • Crohn’s Disease
  • Esophageal Disease
  • Esophageal Cancer
  • Hemorrhoids
  • Liver Disease
  • Pancreatic Disease
  • Pancreatic Cancer
  • Ulcerative Colitis

Hepatology, or hepatobiliary medicine, encompasses the study of the liver, pancreas, and biliary tree, while proctology encompasses the fields of anus and rectum diseases. They are traditionally considered sub-specialties of gastroenterology.

Gastroenterology Tests and Procedures


We perform a number of diagnostic and therapeutic procedures including colonoscopy, endoscopy, endoscopic retrograde cholangiancreatography (ERCP), endoscopic ultrasound and liver biopsy.


A colonoscopy is a procedure that enables your gastroenterologist to evaluate the inside of your colon, using a colonoscope – a long, flexible tool with a camera and a light, which is inserted into the anus. There are many reasons why your doctor may request a colonoscopy. Often it is performed as a part of a screening program for colon cancer; however, your doctor may also utilize this diagnostic test to investigate:

  • Sudden changes in bowel habits
  • Blood in the stool
  • Inflamed mucous lining of your intestine
  • Abdominal pain
  • Ulcers
  • Diarrhea

Or to analyze further abnormalities in the colon discovered through an x-rays or CT scan.

If you have a family history of cancer or polyps, we encourage you to call us at 845-794-0996 to schedule an appointment with our gastroenterologist.

Upper Gastrointestinal Endoscopy (EGD)

An upper GI endoscopy or EGD (esophagogastroduodenoscopy) is a procedure enables your doctor to examine the esophagus, stomach and the upper small bowel. This procedure utilizes an endoscope – a long, flexible tool that is inserted into your mouth and throat, which sends video images to a monitor for visual examination.

In addition to video monitoring, the endoscope can also be used to take tissue samples, remove objects stuck in the upper GI tract, inject air or fluid, or to help facilitate other procedures such as endoscopic surgery.

There are a number of reasons your doctor may want to perform an endoscopy, including the diagnosis or treatment of a number of symptoms or conditions, including, but not limited to:

  • Gastroesophageal reflux disease (GERD)
  • Trouble swallowing
  • Upper belly or chest pain
  • Vomiting or bleeding in the upper GI tract
  • Ulcers and tumors
  • Celiac disease
  • Crohn’s disease

Endoscopic Retrograde Cholangiopancreatography (ERCP)

This procedure is used to diagnose and treat disorders or disease of the liver, pancreas, gallbladder, and bile ducts. During an endoscopic retrograde choloangiopancreatography, or ERCP, our doctors utilize both an X-ray and a endoscope to see the examine these organs. An ERCP may assist in the diagnosis of the following conditions or symptoms:

  • Jaundice
  • Cancer of the liver, pancreas or bile ducts
  • Pancreatitis
  • Blockages, stones, or fluid leakage in bile ducts
  • Tumors

Liver Biopsy

A liver biopsy entails the process of removing and analyzing a small piece of tissue from the liver and is often performed to help diagnose the cause and severity of a patient’s liver disease. In addition to the initial diagnosis of liver disease, biopsies may also be conducted throughout a patient’s treatment to monitor effectiveness overtime.

A liver biopsy may be used in an effort to diagnose or monitor the following conditions in our patients, including, but not limited to:

  • Alcoholic liver disease
  • Chronic Hepatitis (B or C)
  • Autoimmune hepatitis
  • Primary Biliary Cirrhosis
  • Wilson’s disease
