Why This Test Is Done

Your doctor may order this test after an endoscopic procedure, such as a polypectomy or resection, to confirm that all abnormal tissue was removed. It helps prevent the recurrence of precancerous growths or cancer in the same area.

What to Expect Before the Test

No special preparation is needed beyond what your doctor instructs. You may be asked to avoid eating or drinking for a few hours before the procedure, depending on the type of endoscopic exam.

Procedure Details

During the test, a small sample of tissue removed during the endoscopic procedure is sent to the lab. The lab examines the tissue under a microscope to check for any remaining abnormal cells.

What the Results Mean

If the test confirms no abnormal cells remain, it means the resection was successful. If abnormal cells are found, further treatment or additional procedures may be needed.

Clinical interpretation
