Summary

The two most commonly used methods to biopsy suspected pancreaticobiliary masses are (1) endoscopic ultrasound guided fine-needle aspiration (EUS-FNA) and (2) cytology brush biopsies obtained during endoscopic retrograde cholangiopancreatography (ERCP). At most centers, the specific method used depends on the availability of the technology and local expertise. Although it is believed that EUS-FNA is more accurate than ERCP brushings, there have been no head-to-head comparisons. The investigators' hypothesis is that EUS-FNA is superior to ERCP in obtaining tissue biopsies of pancreaticobiliary tumors, and the investigators aim to directly compare the two techniques.

Conditions

  • Pancreaticobiliary Cancers
  • Jaundice
  • Bile Duct Obstruction

Interventions

PROCEDURE

ERCP

Endoscopic retrograde cholangiopancreatography (ERCP) is usually clinically indicated to place a stent (a plastic or metal tube) in the bile duct. The ERCP procedure is an endoscopic exam during which a small catheter or wire is placed into the bile duct from the point at which it connects to the small intestine. During such a procedure a stent can then be placed to help drain the bile across the site of blockage, and thereby treat your jaundice.

PROCEDURE

EUS FNA

Endoscopic ultrasound (EUS) is a procedure in which a flexible tube with a tiny camera and ultrasound probe at the tip is placed through the mouth, down the esophagus, and into the stomach and duodenum (first part of the small intestine where bile flows from the bile duct into the intestine). This allows the doctor performing the EUS to get a much closer view of your pancreas and bile duct. If a suspicious mass is seen, a small sample of the mass (biopsy) is taken using fine needle aspiration (FNA). FNA involves the use of a thin hollow needle to extract cells for diagnostic purposes and is considered safer and less invasive than surgical biopsies.
