Diagnose chronic pancreatitis & esophageal, stomach & rectal cancers.
This minimally invasive procedure combines endoscopy with ultrasound. It can be used to diagnose chronic pancreatitis and esophageal, stomach and rectal cancers. It can also be used to treat abdominal pain associated with chronic pancreatitis and pancreatic cancer. An ultrasound transducer is placed at the end of an endoscope and advanced into the intestine. A transducer is a device that receives a signal in the form of one type of energy and converts it to another form.
The ultrasound transducer produces a high-resolution image of the gastrointestinal lining and other structures located beyond the gastrointestinal wall. Complications such as perforation are rare. The patient should not eat or drink anything for at least 6 hours prior to the procedure.
