Biopsies
When a scan shows a lump in the liver, lung, kidney, lymph nodes, thyroid, breast or bone, a small tissue sample is often needed for diagnosis. Under local anaesthesia, a needle is guided precisely to the lesion with ultrasound or CT, and the sample is sent to pathology.
Drainages
- Abscess and fluid drainage: a thin tube drains pus or fluid from the liver, abdomen, chest or pelvis.
- PTBD (percutaneous transhepatic biliary drainage): relieves jaundice caused by a blocked bile duct, with stenting when needed.
- Percutaneous nephrostomy: drains a blocked kidney.
- Pleural and ascitic drainage: removes fluid around the lungs or in the abdomen.
What to expect
Most procedures take under an hour. You may be asked to fast for a few hours and to stop blood thinners beforehand, which will be advised in advance. Many patients go home the same day.
Frequently asked questions
Is a biopsy painful?
The area is numbed with local anaesthesia. You may feel pressure, and mild soreness for a day or two is common.
When will I get the results?
