tumor in this patient population," said study lead author Banke Agarwal, MD, Saint Louis University School of Medicine. "We found that EUS and/or an EUS-FNA for diagnosing a pancreatic neoplasm was 99.1 percent accurate with 88.8 percent sensitivity and 100 percent specificity."
Endoscopic ultrasound consists of a flexible endoscope which has a small ultrasound device built into the end. The ultrasound component produces sound waves that create visual images of the digestive tract which extend beyond the inner surface lining. EUS can be used to evaluate an abnormality below the surface such as a growth that was detected at a prior endoscopy or by X-ray. EUS can also be used to diagnose diseases of the pancreas, bile duct, and gallbladder when other tests are inconclusive, and can be used to determine the stage of cancers. Tissue samples, using a fine needle aspiration technique (FNA), can be obtained in real time with EUS guidance should an abnormality be seen.
Patients and Methods
This study was a retrospective analysis of 110 patients, mean age 60.3 years, from a prospectively maintained database of patients who underwent an EUS and/or EUS-FNA at St. Louis University Hospital between March 2002 and March 2006 for suspected pancreatic cancer based on an abnormal CT and/or MRI who were reported as having an enlarged HOP or dilation of the PD (with or without a dilated common bile duct). An EUS examination was initially performed by using a radial echoendoscope. Whenever a suspicious "mass" was identified on radial EUS, an FNA was performed using a linear echoendoscope. Fine needle aspirates were submitted for cytology and biochemical analysis. A final diagnosis was based on definitive cytology, surgical pathology or clinical follow up of 12 months or more (median follow up was 16 months).
Results
Researchers found that 6 percent of patients referred because of an enlarged HOP on a CT and/or an MRI and 11
