Record Comparison and Observation — Mary's Decision
Review prior imaging, symptoms, liver studies, surgery history, and medicines before ordering another test. This option became relevant after mary sought specialist review because the radiology recommendation did not mention the stable older measurement.
Best for: A stable patient with unchanged dilation and reassuring clinical findings. For Mary, the main context was older imaging showed little meaningful change.
Limitations: Observation is unsafe when jaundice, fever, abnormal bilirubin, progressive dilation, or concerning imaging features are present. This mattered because a single measurement was treated like a diagnosis before the context was reviewed.
Takeaway: A stable number over time can prevent an unnecessary invasive procedure. Mary's path used this distinction to avoid another temporary workaround.
MRCP or EUS — Mary's Decision
Use noninvasive duct mapping or high-resolution endoscopic imaging to identify stones, strictures, or pancreatic and ampullary lesions. This option became relevant after mary sought specialist review because the radiology recommendation did not mention the stable older measurement.
Best for: A patient with unexplained dilation or an intermediate probability of obstruction. For Mary, the main context was older imaging showed little meaningful change.
Limitations: These tests diagnose but usually do not restore drainage during a dangerous obstruction. This mattered because a single measurement was treated like a diagnosis before the context was reviewed.
Takeaway: Choose the test that answers the next question with the least avoidable risk. Mary's path used this distinction to avoid another temporary workaround.
Therapeutic ERCP — Mary's Decision
Drain the duct, remove a stone, open selected strictures, obtain duct samples, or place a temporary stent. This option became relevant after mary sought specialist review because the radiology recommendation did not mention the stable older measurement.
Best for: A patient with confirmed obstruction, cholangitis, or another treatable duct lesion. For Mary, the main context was older imaging showed little meaningful change.
Limitations: ERCP can cause pancreatitis, bleeding, infection, or perforation and should not be used only to remeasure the duct. This mattered because a single measurement was treated like a diagnosis before the context was reviewed.
Takeaway: Use ERCP when treatment is expected. Mary's path used this distinction to avoid another temporary workaround.
