Complications of Cirrhosis Treatment Part 1

The treatment complications of cirrhosis include Edema and Ascites, Bleeding from Varices, Hepatic encephalopathy, Hypersplenism, Spontaneous bacterial peritonitis (SBP). In Complications of Cirrhosis Treatment Part 1, I will give more detail information about edema and ascites, also bleeding from varices.

Edema and Ascites

The salt and water retention can lead to swollen ankles and legs (edema) or abdomen (ascites) in patients with cirrhosis. Doctors often advise patients with cirrhosis of limiting the intake of salt (sodium) and fluid to reduce edema and ascites. The amount of salt in the diet is generally limited to 2 grams per day and the liquid to 1.2 liters per day. In most patients with cirrhosis, however, salt and fluid restriction is not enough, and diuretics should be added.

Diuretics are drugs that act on the kidneys to promote excretion of salt and water in urine. A combination of the diuretic spironolactone (Aldactone) and furosemide can reduce or eliminate the edema and ascites in most patients. During treatment with diuretics, it is important to monitor kidney function by measuring blood levels of blood urea nitrogen (BUN) and creatinine to determine if a diuretic is used too. Too many diuretics can cause kidney dysfunction leading to elevated urea and creatinine in blood.

Sometimes when diuretics are not working (in this case, is known as refractory ascites), a long needle or catheter is used to make the ascitic fluid directly into the abdomen, a procedure called abdominal paracentesis. It is common to remove large quantities (liters) of fluid in the abdomen when ascites is abdominal distention causing pain and / or difficulty breathing, as it restricts the movement of the diaphragm.

Another treatment of refractory ascites is a procedure known as porto-systemic shunt transjugular intravenous TIPS.

Bleeding from Varices

If large varices develop in the stomach, esophagus or superior in patients with cirrhosis are at risk of serious bleeding due to rupture of these varices. Once varices have bled, they tend to bleed and the likelihood that patients die each episode of bleeding is high (30% -35%). Therefore, treatment is needed to prevent the episode (original) first bleeding and rebleeding. Treatments include medications and procedures to reduce the pressure in the portal vein and procedures to destroy varicose veins.

* Propranolol (Inderal), a beta blocker, is effective in reducing the pressure in the portal vein and is used to prevent the initial hemorrhage and rebleeding of varices in patients with cirrhosis. Another class of oral drugs that lower portal pressure is nitrates, eg isosorbide dinitrate (Isordil). Nitrates are often added to propranolol, while propranolol alone is not enough to reduce portal pressure and prevent bleeding.

* Octreotide (Sandostatin) also reduces the pressure of the portal vein and is used to treat variceal bleeding.

* During upper endoscopy (EGD) or sclerotherapy or ligation can be performed to remove varicose veins and stop the bleeding and prevent rebleeding. Sclerotherapy involves injecting small doses of sclerosing solution into varicose veins. Sclerosing solutions cause inflammation and scarring and varicose veins, erasing in the process. Band ligation is the use of rubber bands around the varices to erase. (Ligation of varicose veins is similar to rubber bands of hemorrhoids.) Complications of sclerotherapy: esophageal ulcers, bleeding ulcers of the esophagus perforation, esophagus, esophageal stricture (narrowing due to scarring that can cause) , dysphagia, mediastinitis (inflammation of the lungs that can cause chest pain), pericarditis (inflammation around the heart can cause chest pain), and peritonitis (infection of the abdominal cavity). Studies have shown that ligation may be slightly more effective with fewer complications than sclerotherapy.

* Transjugular intrahepatic portosystemic shunt (TIPS) is a surgical procedure to relieve pressure in the portal vein. TIPS is performed by a radiologist inserts a catheter (tube) into a vein in the neck to the inferior vena cava and hepatic vein in the liver. The stent then so that one end is in the high pressure portal vein and the other is in the low-pressure hepatic vein. This blood will not pass through the tube around the liver and therefore decreases the pressure in the portal vein and varicose veins and prevents bleeding varices. TIPS is particularly useful in patients unresponsive to beta-blockers, sclerotherapy of varicose veins or bands. (TIPS is also useful in the treatment of patients with ascites do not respond to salt and fluid restriction and diuretics.) TIPS can be used in patients with cirrhosis to prevent variceal bleeding while patients are awaiting transplant hepático. The most common side effect of TIPS is hepatic encephalopathy. Another major problem is the development advice of narrowing and occlusion of the stent, causing the recurrence of portal hypertension and variceal bleeding and ascites. The ranges of estimated frequency of stent occlusion in 30% -50% in 12 months. Fortunately, there are ways to open occluded stents. Other complications include bleeding boards due to accidental perforation of the capsule of the liver or bile duct, infection, heart failure and liver failure.

* A surgical operation to create a bypass (step) of the vein portal vein high pressure to low pressure can reduce blood flow and portal vein pressure and prevent variceal bleeding. The surgery is called distal splenorenal shunt (DSRS). To consider a bypass surgery in patients with portal hypertension who have early cirrhosis. (The risks of bypass surgery for these patients is lower in patients with advanced cirrhosis.) During DSRS, the surgeon separates the splenic vein, portal vein and attached to the renal vein. Blood is diverted from the spleen to the liver, lowering blood pressure in the portal vein and varices and prevention of variceal bleeding.

Hepatic Cirrhosis Complication Symptoms and Signs Part 2

Previously, we have discussed about signs and symptoms of hepatic cirrhosis complications such as edema and ascites, spontaneous bacterial peritonitis (SBP), and Bleeding esophageal varices in Part 1. Now we will discuss the continuation of hepatic cirrhosis complication symptoms and signs such as hepatic encephalopathy, hepatorenal syndrome, hepatopulmonaire syndrome, hypersplenism and hepatocellular carcinoma (liver cancer) details as below.

Hepatic Encephalopathy

Some of the proteins in food that escapes digestion and absorption is used by bacteria normally present in the intestine. While the utilization of protein for their own purposes, bacteria that cause substances emitted in the intestine. These substances can be absorbed by the body. Some of these substances, eg ammonia, can have toxic effects on the brain. Normally, these toxic substances are transported from the intestine into the portal vein to the liver where they are eliminated from the blood and detoxification.

As mentioned above, when cirrhosis is present, liver cells can not function normally, either because they are damaged or because they have lost their normal relationship with the blood. In addition, some blood in the portal vein bypasses the liver through other veins. The result of these anomalies is that toxic substances can be removed by the liver cells, and instead, toxic substances accumulate in the blood.

When toxic substances accumulate sufficiently in the blood, brain function is disrupted, a condition called hepatic encephalopathy. Sleeping during the day instead of night (reversal of normal sleep pattern) is one of the first symptoms of hepatic encephalopathy. Other symptoms include irritability, inability to concentrate or perform calculations, memory loss, confusion, depression, or levels of consciousness. Ultimately, severe hepatic encephalopathy leading to coma and death.

Toxic chemicals also cause the brain of patients with cirrhosis very sensitive to drugs that are normally filtered and detoxified by the liver. The dose of many drugs that are normally liver detoxification should be reduced to avoid toxic accumulation in cirrhosis, particularly sedatives and drugs used to promote sleep. Alternatively, medications may be used which need not be decontaminated or disposed of the body by the liver, for example, drugs that are eliminated by the kidneys.

Hepatorenal Syndrome

Patients with cirrhosis can develop an intensification of hepatorenal syndrome. This syndrome is a serious complication in which kidney function is reduced. This is a malfunction in the kidneys, i.e. no physical damage to the kidneys. In contrast, the reduction function is due to changes in how blood flows through the kidneys themselves. Hepatorenal syndrome is defined as the progressive inability of the kidneys to clear substances from the blood and produce adequate amounts of urine, but some other important functions of the kidneys, such as salt retention are maintained. If liver function or a healthy liver is transplanted into a patient with hepatorenal syndrome, the kidneys usually start working normally. This suggests that reduced renal function is the result of accumulation of toxic substances in the blood when the liver fails. There are two types of hepatorenal syndrome. An error occurs gradually in recent months. The other is quickly over a week or two.

Hepatopulmonaire Syndrome

More rarely, some patients with advanced cirrhosis may develop hépatopulmonaire syndrome. These patients may have difficulty breathing because of certain hormones released in advanced cirrhosis causes the lungs to function abnormally. The fundamental problem in the lungs is not enough blood flows through tiny blood vessels in the lungs that are in contact with the alveoli (air sacs) of the lungs. The lung blood is diverted around the alveoli and can not collect enough oxygen in the alveoli. Consequently, the patient has trouble breathing, especially with exertion.

Hypersplenism

The spleen normally acts as a filter to remove more red blood cells, white cells and platelets (small particles that are important for blood clotting.). The blood that flows in the rate reaches the blood in the veins of the intestine. With increasing pressure in the portal vein in cirrhosis, which blocks blood flow further and further into the spleen. Blood “backs and accumulates in the spleen, the spleen and swell in size, a condition known as splenomegaly. Sometimes, the spleen is so swollen that causes abdominal pain.

As the spleen, cells from the blood leaks and more and more until the number of platelets in the blood are reduced. Hypersplenism is the term used to describe this condition, and is associated with a low number of red blood cells (anemia), low white blood cell count (leukopenia), and / or a low platelet count (thrombocytopenia). Anemia can cause weakness, infections can cause leukopenia, thrombocytopenia and may inhibit blood clotting and cause prolonged bleeding.

Hepatocellular Carcinoma ( liver cancer )

Cirrhosis due to a cause increases the risk of primary liver cancer (hepatocellular carcinoma). Principal means that the tumor originates in the liver. A secondary liver cancer is one that comes from other parts of the body and spread (metastasize) to the liver.

The most common symptoms and signs of primary liver cancer are abdominal pain and swelling, enlarged liver, weight loss, fever. In addition, cancers of the liver can produce and release a number of substances, including those that cause an increase in red blood cells (polycythemia), blood sugar (hypoglycemia) and high calcium levels (hypercalcemia).
