Who is it for?
Pancreatic biopsy establishes the type of a pancreatic mass. For patients in whom oncologic treatment (chemotherapy, radiotherapy) is planned, tissue diagnosis is usually mandatory before starting.
There are two main routes: percutaneous image-guided biopsy through the skin, and endoscopic ultrasound (EUS)-guided biopsy. The choice depends on the mass’s location, size and centre resources, decided with the relevant specialties — the two are complementary, not rivals.
How it is done — step by step (percutaneous)
Planning
The safest track is planned with ultrasound/CT; bowel and vessel neighbours are assessed one by one.
Anaesthesia
Local anaesthesia, with light sedation added for comfort when needed.
Sampling
A cutting needle takes samples under image guidance; each pass lasts seconds.
Observation
Close observation for a few hours follows the procedure.
What to expect on the day
You will be asked to fast; blood thinners are adjusted in advance.
The procedure itself takes minutes; observation is the main time. Most patients go home the same day, some after one night.
Risks and Limitations
The pancreas is a delicate organ; the specific risk to know is a rise in pancreatic enzymes and, rarely, pancreatitis after the procedure. Bleeding and neighbouring organ injury are rare; planning and image guidance minimize them.
A limit: because of inflammatory tissue around the mass, the sample is occasionally non-diagnostic; repeat or EUS sampling is then considered.
Recovery and follow-up
Rest is advised on the day; most patients resume normal life the next day. Contact us for severe abdominal pain, fever or vomiting.
Pathology is usually ready within days to one or two weeks; results are reviewed with the oncology/surgical teams and treatment is set without delay.

Frequently Asked Questions
Can treatment start without a biopsy?
Tissue diagnosis is usually mandatory before oncologic drug therapy; the right treatment requires the right diagnosis. In selected surgical scenarios the team may follow a different path.
Percutaneous or EUS?
Both are valid; the choice follows the mass’s location and centre resources, decided with the relevant specialties.
What does pancreatitis risk mean?
A transient pancreatic irritation can occur; rarely, abdominal pain with enzyme elevation develops. Observation exists to catch this early, and it usually settles with supportive care.
Is it painful?
Local anaesthesia (with sedation if needed); the sampling takes seconds. Mild soreness afterwards is controlled with medication.
When is the result ready?
Usually within days to one or two weeks; the oncologic plan is built promptly on it.
Can I go home the same day?
Usually yes; depending on the mass’s location, an overnight stay may be planned in advance.
