Why is SpyGlass Performed?

Occasionally, standard ERCP techniques are limited in the evaluation and treatment of difficult bile duct and pancreatic duct stones and assessment of indeterminate strictures.  An indeterminate stricture is a blockage that occurs in either the bile duct or pancreatic duct that may be suspicious for cancer without a definitive tissue diagnosis.  Historically, these patients may have undergone an invasive surgical resection without a tissue diagnosis.  SpyGlass is also performed for the evaluation and management of common bile duct and pancreatic duct stones.
