It is also used for diagnosis and drainage of pancreatic cysts and for management of pain in pancreatic cancer patients.

management of diseases such as chronic pancreatitis and to alleviate malignant disease. Through the use of special equipment, this procedure can be carried out for patients with surgically altered anatomy such as prior gastric bypass surgery.

The Endoscopy Center is the only site in RI where single balloon enteroscopy is performed.
