Approximately 2–3% of patients undergoing liver biopsy require hospitalization for the management of an adverse event. [8] [9] Thirty percent of patients experience significant pain during the procedure. [10] Significant bleeding after a liver biopsy occurs in 1–2 out of 100 patients who are biopsied.
Sedation (to reduce irritability and agitation of the subject during procedure) with analgesia (painkillers) and vital signs monitoring should be set up. Before the procedure, bedside ultrasound is done to confirm the position of the dilated bile ducts in the liver. The puncture site is then marked.
The region can be directly visualized with the endoscopic camera while various procedures are performed. A plastic catheter or cannula is inserted through the ampulla, and radiocontrast is injected into the bile ducts and/or pancreatic duct. Fluoroscopy is used to look for blockages, or other lesions such as stones. [8] [9]
hepat- : related to the liver, from the latin hēpatītis, from the latin hēpar, Greek loanword, originally ηπαρ, hēpar, meaning "liver" hyster- : related to the uterus, from Neo-Latin hysteria, itself ultimately from the Greek ύστέρα, hústéra, meaning "womb, uterus" lamino- : related to the lamina (posterior aspect of vertebra)
The surgery involves exposing the porta hepatis (the area of the liver from which bile should drain) by radical excision of all bile duct tissue up to the liver capsule and attaching a Roux-en-Y loop of jejunum to the exposed liver capsule above the bifurcation of the portal vein creating a portoenterostomy.

Percutaneous transhepatic cholangiography (PTC): Examination of liver and bile ducts by x-rays. This is accomplished by the insertion of a thin needle into the liver carrying a contrast medium to help to see blockage in liver and bile ducts. Endoscopic retrograde cholangiopancreatography (ERCP). Although this is a form of imaging, it is both ...
A biopsy is a small piece of tissue removed primarily for the purposes of surgical pathology analysis, most often in order to render a definitive diagnosis. Types of biopsies include core biopsies , which are obtained through the use of large-bore needles, sometimes under the guidance of radiological techniques such as ultrasound , CT scan , or ...
Like most liver tumors, the anatomy and location of the adenoma determines whether the tumor can removed laparoscopically or if it requires an open surgical procedure. [7] Hepatocellular adenomas are also known to decrease in size when there is decreased estrogen or steroids (e.g. when estrogen-containing contraceptives, steroids are stopped ...
