A biopsy may be conducted when a doctor suspects hepatitis or other liver disorders. There are two general processes. In first type of procedure a special needle is inserted into the liver to get a tissue sample. The other one is performed laparoscopically, wherein long and thin tools are inserted into the abdomen facilitating small incisions. The laparoscopic process allows sampling a particular region of the liver.
Biopsy instrument: 14 gauge 20 cm biopsy needle. Ultrasound machine with a potential visualizing liver (3-7 MHz) and alcohol or ultrasound gel
Local anesthetic, (almost 10 ml mepivacaine), scalpel blade, skin staples, or 2/0 non-absorbable synthetic suture material (monofilament nylon) are consumed.
Sedation and local anesthesia will become effective within 10 minutes. Aseptic preparation will also take 10 minutes.
