Why Are Biopsies Taken During an Upper Endoscopy?
If your gastroenterologist takes a biopsy during an upper endoscopy, it does not automatically mean cancer is suspected. Biopsies are routinely used to evaluate many digestive conditions, including inflammation, celiac disease, infection and changes that may not be visible through the camera alone.
A biopsy is a very small sample of tissue collected through the endoscope. A pathologist then examines that tissue under a microscope or performs other laboratory testing.
Why Take a Biopsy If the Tissue Looks Normal?
Some digestive conditions cause microscopic changes without creating an obvious ulcer, mass or area of inflammation. The lining may look normal during the procedure even though a tissue sample reveals useful diagnostic information.
For that reason, a physician may take several small samples from different locations based on the symptoms being investigated. This can be a routine part of a thorough examination.
What Can an Upper-Endoscopy Biopsy Help Evaluate?
Depending on where the samples are taken and why the procedure was ordered, biopsies may help evaluate:
Inflammation in the esophagus, stomach or duodenum
Changes associated with Barrett’s esophagus
Celiac disease
Helicobacter pylori infection
Eosinophilic esophagitis
Ulcers or abnormal tissue
Precancerous or cancerous cellular changes
This list is not exhaustive. Your gastroenterologist will decide whether biopsies are needed based on your symptoms, history and procedure findings.
Does a Biopsy During Endoscopy Hurt?
Patients generally do not feel a biopsy being taken from the digestive lining. Small instruments pass through a channel inside the endoscope to collect the sample. Sedation and, in many cases, throat-numbing medication are used to keep the patient comfortable during the overall procedure.
You may have a temporary mild sore throat or bloating after the endoscopy, but this is related to the procedure rather than feeling tissue samples being removed.
Does a Biopsy Mean the Doctor Found Something Serious?
Not necessarily. Biopsies are used for many reasons and are often collected to confirm or rule out common, treatable conditions. They may also be taken as part of monitoring a previously diagnosed condition.
The appearance of tissue during the procedure cannot always provide a final answer. Laboratory examination gives the physician more detailed information and helps guide treatment or follow-up.
How Long Do Endoscopy Biopsy Results Take?
Your gastroenterologist may discuss the visual findings shortly after the procedure, but biopsy results are not immediate. A pathology laboratory must process and examine the samples. Results commonly take several days or longer, depending on the testing required and the laboratory.
Before leaving, ask:
How will I receive my results?
Approximately when should I expect them?
Who should I contact if I have not received them?
Will I need a follow-up visit?
Do not assume that a delay means something abnormal was found. Processing times vary.
What Can the Pathology Report Say?
The report may describe whether tissue is normal or shows inflammation, infection, cellular changes or another finding. Medical terminology in pathology reports can be difficult to interpret without context.
Wait for your gastroenterologist to explain what the result means for you. The same term can have different implications depending on the biopsy location, symptoms, medication history and other test results.
Is Bleeding Expected After an Upper-Endoscopy Biopsy?
Clinically significant bleeding after a routine biopsy is uncommon, but every procedure has potential risks. Follow your discharge instructions carefully. Seek medical attention for vomiting blood, material that looks like coffee grounds, black or bloody stool, worsening chest or abdominal pain, fever, trouble breathing or worsening swallowing problems.
