What This Test Measures

During an endoscopy, the physician examines the pancreas and surrounding structures and assesses how deeply any abnormal tissue or tumor has grown into the pancreatic wall or tissue layers. The result is reported as a depth of invasion category rather than a simple number.

How the Procedure Is Done

An endoscope (a thin, flexible tube with a camera) is passed through the mouth into the upper digestive tract, and specialized techniques such as endoscopic ultrasound may be used to view the pancreas. The physician visually and sonographically evaluates the depth of any lesion.

What the Results Mean

A greater depth of invasion generally indicates more extensive disease, which can affect decisions about surgery, staging, and other treatment options. Your care team interprets the result together with imaging, biopsy, and other findings.

How to Prepare

Preparation usually involves fasting before the procedure and following your doctor's instructions about medications. Be sure to tell your care team about any blood thinners, allergies, or other health conditions.

Reference range

INR: 0.8-1.2 (warfarin: 2.0-3.0)N/A

Specimen: serum

Inform your healthcare provider if you are taking blood thinners. No special preparation required.

Clinical interpretation

How abnormal results are interpreted and what conditions they suggest.

Depth of invasion is an important prognostic factor for pancreatic lesions because deeper invasion often correlates with more advanced disease and may influence whether surgery is an option. It is used alongside pathology and imaging to guide staging and treatment planning. This test does not provide a numeric reference range; findings are reported descriptively by the endoscopist.

Frequently asked questions

Is this a blood test?
No. This is an assessment made during an endoscopic procedure, not a laboratory blood test.
Will I be sedated during the procedure?
Sedation is commonly used for endoscopic procedures. Your care team will discuss the type of sedation and what to expect beforehand.
Can I eat before the test?
You will usually be asked to fast for several hours before the procedure. Follow the specific fasting and medication instructions given by your doctor.
