GI Endoscopy

Endoscopy is a nonsurgical procedure used to diagnose gastrointestinal disease. An endoscopy involves examining the inside of a person's body using a medical device consisting of a long, thin, flexible tube that has a light and a video camera. Penn Gastroenterology performs over 26,000 procedures annually.

Our modern facilities have the latest technological advancements for diagnosis and treatment of gastrointestinal diseases including:

  • Endoscopic laser therapy, ultrasound and endoprosthetic (stent) placement.
  • Balloon dilation for achalasia.

Types of Advanced Endoscopy Procedures

We have a variety of advanced endoscopic procedures that are designed to keep patients as comfortable as possible. Advanced endoscopy refers to interventional endoscopic procedures that are minimally invasive and provide a safe, effective alternative to more invasive diagnostic techniques such as surgery. This highly specialized field offers unique opportunities for gastroenterologists to detect GI cancers early, remove polyps and treat more complicated diseases.

Upper GI Endoscopy

An upper endoscopy uses a tiny camera and long flexible tube, called an enteroscope, to examine the esophagus, stomach, and upper part of the gastrointestinal tract.

Flexible Sigmoidoscopy

Flexible sigmoidoscopy is a test that uses a sigmoidoscope, a long flexible tube that examines the rectum and the colon for abnormalities.


A colonoscopy is a procedure that uses a long flexible tube called a colonoscope to examine parts of the rectum and colon for abnormalities and disease.

Our approach to treatment combines a highly experienced team using the most advanced minimally invasive tools and leveraging the many resources available at Penn's Abramson Cancer Center.

Endoscopic Ultrasound (EUS)

Specialized techniques such as endoscopic ultrasound (EUS) are important tools in the diagnosis and treatment of gastrointestinal tumors. EUS is critical to the management of digestive cancer, a category that includes pancreatic cancer, bile duct cancer and esophageal cancer. Because of its unique capability to allow physicians to get extremely close to the abdominal organs, more accurate and detailed images are obtained. EUS combines the flexibility of an endoscope (a long tube inserted in the mouth or the rectum) with the high resolution imaging of ultrasound to produce images of exceptional quality.

The Most Precise Diagnosis and Treatment of Digestive Cancer

"Penn is one of the most highly regarded centers in the world for the application of and training in EUS for digestive diseases and related disorders."
– Gregory G. Ginsberg, MD, Director of Endoscopic Services at Penn

ERCP (Endoscopic Retrograde Cholangiopancreatography)

ERCP uses a flexible tube that is passed through the mouth, esophagus and stomach into the first part of the small intestine. The test is used to examine the pancreas, bile ducts, liver, and gallbladder for abnormalities and disease.

Capsule Endoscopy

Capsule endoscopy utilizes a tiny wireless camera to take pictures of the digestive tract. The camera sits inside a vitamin-sized capsule that is swallowed and travels through the digestive tract transmitting images.

Esophageal Manometry and Impedance

Esophageal manometry is an examination of the esophagus using a flexible catheter that is inserted through the nasal passage. The test detects abnormalities or disease of the esophagus.
