Advanced Endoscopy

Roswell Park Comprehensive Cancer Center’s Advanced Endoscopic Services combine leading-edge technology with minimally invasive techniques to diagnose and treat malignant and benign digestive conditions.

Our Endoscopy Center brings together Advanced Endoscopy and Interventional Pulmonology services into one state-of-the-art facility where more than 90 percent of procedures are performed on an outpatient basis. With our unique capabilities, we offer minimally invasive options in place of traditional surgery whenever possible, caring for patients in a way that affords a quicker recovery, less pain and fewer side effects.

Endoscopic Ultrasound

A thin, lighted tube (endoscope) is passed through the patient's mouth and stomach into the first part of the small intestine. At the tip of the endoscope is an ultrasound device. The doctor slowly withdraws the endoscope from the intestine toward the stomach to make images of the pancreas and surrounding organs and tissues. A biopsy may be taken during this procedure to confirm diagnosis.

Endoscopic Retrograde Cholangiopancreatography (ERCP)

After an endoscope is passed through the patient's mouth, stomach, and into the first part of the small intestine, a smaller tube (catheter) is passed through the endoscope and into the bile ducts and pancreatic ducts. Dye is injected through the catheter to the duct, and x-rays then show whether the ducts are blocked from a tumor or other condition.

Electrohydraulic Lithotripsy of Complex Bile Duct Stones

Electric sparks are delivered in short pulses to induce shock waves that fragment large bile duct stones.


An endoscopic procedure used to evaluate, treat or take biopsy of bile or pancreatic ducts.

Endoscopic Radiofrequency Ablation

A procedure that uses radio waves to heat and destroy abnormal cells. The radio waves travel through electrodes (small devices that carry electricity). Radiofrequency ablation may be used to treat cancer and other conditions.

Capsule Endoscopy

A procedure used to look at the inside of the intestines and other parts of the digestive tract. The patient swallows a capsule about the size of a large pill. The capsule contains a tiny wireless camera that travels through the digestive tract. It takes pictures of the inside of the digestive tract and sends them to a small recorder that is worn on the patient’s waist or shoulder. The pictures are then viewed on a computer by the doctor to check for signs of disease. The capsule passes out of the body during a bowel movement.

Double Balloon Enteroscopy

Balloons attached to the endoscope are inflated to allow the physician to pass the endoscope deeper into the small intestine.

Endoscopic Photodynamic Therapy

Endoscopic photodynamic therapy is a targeted anticancer treatment — one that kills tumor cells without permanently damaging surrounding tissue. The treatment involves the administration of a nontoxic drug that settles in tumor cells, followed by the application of laser light to the tumor, thereby activating the drug and killing the cancer. At Roswell Park, it is used to treat various types of cancer, including cancers of the skin, lung, breast, gynecological cancers, esophagus, pleura, head and neck - mouth and larynx.

Endoscopic Mucosal Resection

Endoscopic mucosal resection (EMR) is a procedure to remove cancerous or other abnormal tissues (lesions) from the digestive tract. Endoscopic mucosal resection is performed with a long, narrow tube equipped with a light, video camera and other instruments. During endoscopic mucosal resection of the upper digestive tract, the tube (endoscope) is passed down your throat to reach an abnormality in your esophagus, stomach or upper part of the small intestine (duodenum). When endoscopic mucosal resection is used to remove lesions from the colon, the tube is guided up through the anus. Although endoscopic mucosal resection is primarily a treatment procedure, it's also used to collect tissues for use in diagnosis. If cancer is present, EMR can help determine if the cancer has invaded tissues beneath the digestive tract lining.
