Endoscopic ultrasound is performed to provide your physician with detailed images of your digestive tract that other endoscopic procedures or imaging tests are unable to provide. It can help diagnose certain conditions that may cause abdominal pain or abnormal weight loss in addition to evaluating previously detected abnormalities including lumps or lesions. EUS is often used to diagnose diseases of the pancreas, bile duct and gallbladder when other tests are inconclusive or conflicting.

Drs. Hiral Shah, Shashin Shan, and Zachary Zator are proud to be three of only a few local physicians who perform endoscopic ultrasound among a number of other advanced endoscopic procedures.

Endoscopic retrograde cholangiopancreatography, or ERCP, is a specialized technique used to study the bile ducts, pancreatic duct and gallbladder. ERCP is performed to treat stones, tumors, or narrow areas of the bile ducts. Many of the physicians at EPGI have extensive experience in ERCP and perform the procedure at Lehigh Valley Health Network – Cedar Crest, Lehigh Valley Health Network – Muhlenberg, and Sacred Heart Hospital.

Double Balloon Entersocopy, or DBE, is also sometimes referred to as “push-pull enteroscopy”. It is the only endoscopic technique that allows complete examination of the small bowel. Dr. Anastasia Shnitser and Dr. Hiral Shah are proud to be the only local physicians performing Double Balloon Enterosocopy. They have been performing the procedure at Lehigh Valley Health Network – Cedar Crest Campus since December 2014.

Radiofrequency Ablation (RFA) therapy is a safe and effective treatment of Barrett’s esophagus. During RFA radio waves are delivered via a catheter to remove diseased tissue of the esophagus while having minimal impact to the healthy tissue. This process is called ablation. Treating Barrett’s esophagus is important because it not only removes diseased tissue, it can prevent the development of Esophageal Cancer.
