Hepatobiliary Surgery
Hepatobiliary surgery consists of highly technical challenging procedures
that deal with all pathological conditions that affect the liver, gallbladder,
bile ducts, pancreas, and duodenum. These conditions can be the result of
congenital abnormalities, inflammation, infection, benign or malignant tumors,
or the result of traumatic injuries.
Over the past 20 years, hepatobiliary surgery has made tremendous
improvements. Before, this type of surgery was very risky, with high morbidity
and mortality rates. Now, due to a better understanding of the anatomy and
improvement of surgical techniques, hepatobiliary surgery has become very safe
and common with a very low death rate. One reason for improved surgical outcome
is the multidisciplinary approach that the transplant and hepatobiliary staff,
together with various other specialties, including internal medicine, oncology,
infectious disease, pathology, and radiology, have formed a better and
comprehensive service dedicated to properly diagnose, treat, and manage any
liver condition.
Major liver resections are now routinely performed with great successes and
long term cures, often without the need for blood transfusions. Tumors that
cannot be removed for various reasons can be destroyed with alternative methods
such as radiofrequency ablation technique or alcohol injections into the tumor.
Other effective modalities include chemotherapy with embolization of the vessels
nourishing the tumor, or through a hepatic artery pump. Improvements in surgical
technique and perioperative care have contributed to the success of
hepatobiliary surgery and better outcomes for the patients.
Services dedicated to treating liver conditions including liver resection,
chemoembolization, radiofrequency ablation, alcohol injection, and transjugular
intrahepatic portosystemic shunting are available under the guidance of
Dr. Wu, who uses advanced techniques to treat
hepatobiliary diseases.
Liver resection is an operation to remove a
portion of the liver. This operation is usually done to remove various types of
liver tumors that are located in the portion of the liver that is removed. The
goal of liver resection is to completely remove the portion of the liver where
the tumor is located and 2 to 3 cm of liver tissue that immediately surrounds
the tumor. After liver resection surgery, the remaining liver
can grow back to its original size in 1 to 2 weeks.
Chemoembolization is a treatment option for patients with liver
cancer. With the aid of an x-ray, a small catheter is inserted in an artery
through the groin. The catheter is then threaded into the hepatic artery, the
artery that provides blood into the liver as well as the liver tumor. Then a
high concentration of chemotherapy is injected directly into the tumor. In
addition to the chemotherapy, the blood supply to the tumor is blocked, or
embolized, by injected particles. Over time, this treatment causes the tumor to
decrease in size or break down completely.
Radiofrequency ablation (RFA) is used to treat tumors that cannot be
surgically removed because of tumor size or location. RFA is a process in which
an electrical current (radiofrequency energy) is delivered to the liver tumor.
Ultrasound is used to precisely place the electrical current. This electrical
current produces heat which destroys the tumor (ablation) without harming
surrounding healthy liver tissue.
Ethanol injection is used to treat liver tumors that may be difficult
to surgically remove. The injection of alcohol into tumors can be beneficial
because the alcohol is toxic to tumors and causes them to dry out and eventually
disintegrate. With the assistance of ultrasound, alcohol is injected through the
skin into the liver tumor. Ethanol injection has been proven beneficial in
helping patients with liver cancer.
Transjugular intrahepatic portosystemic shunt (TIPS) is a non-surgical
procedure used to control bleeding from varices and reduce portal hypertension,
which results from scarring or other blockage that increases the pressure in the
portal vein in the liver. A radiologist performs this procedure using an x-ray.
A tunnel is formed in the liver that connects the portal vein to a hepatic vein.
The stent is then placed in the tunnel to keep it open. This tunnel serves as a
new pathway from the portal vein to the hepatic artery that helps reduce portal
hypertension and bleeding from varices.
