Liver Biopsy

During a liver biopsy, the physician examines a small piece of tissue from your liver for signs of damage or disease. A special needle is used to remove the tissue from the liver. The physician decides to do a liver biopsy after tests suggest that the liver does not work properly. For example, a blood test might show that your blood contains high levels of liver enzymes or too much iron or copper. An x-ray could suggest that the liver is swollen. Looking at liver tissue itself is the best way to determine whether the liver is healthy or what is causing it to be damaged.

ESWL (Extracorporal Shockwave Lithotripsy)

ESWL is used to break up stones in the kidney that are less than 2 cm in size. It can also be used for stones in the ureter, although other techniques may be preferred.

Lithotripsy involves using sound waves to break kidney stones. The sound wave travels through the body but cannot pass through the stone. The stone has to absorb energy, which causes it to break, as if it was being directly hit.

During the procedure, you will need to lie very still to allow the sound wave to be focused effectively. A drip will be placed and pain relievers will be given.

A cushion filled will fluid will be raised under the table to rest under the kidney. Using x-rays, the stone is located and moved in line with the sound wave generator. Initially waves of low power are used, building up gradually in strength. Approximately 2,000 pulses are delivered to the stone. A tapping sound is heard throughout the treatment.

Paracentesis

Paracentesis is a procedure to remove fluid that has accumulated in the abdominal cavity, a condition called ascites. Ascites may be caused by infection, inflammation, abdominal injury or other conditions, such as cirrhosis or cancer. The fluid is removed using a needle inserted through the abdominal wall and then sent to the lab for analysis to determine the cause of the fluid buildup. Paracentesis may also be done to drain the fluid to help cancer or chronic cirrhosis patients ease their pain.

The peritoneum, the lining of the abdominal cavity, supports the organs in the abdomen and helps protect them from infection. The inside surface of the peritoneum produces a very small amount of peritoneal fluid that allows the organs in the abdomen to slide against the peritoneum and each other.

Paracentesis may be done to:
