Cirrhosis of the Liver (relates to Chapter 42, “Nursing Management: Liver, Biliary Tract, and Pancreas Problems,” in the textbook)
2
Description A chronic, progressive disease of the liver –Extensive parenchymal cell degeneration –Destruction of parenchymal cells A chronic, progressive disease of the liver –Extensive parenchymal cell degeneration –Destruction of parenchymal cells
3
Description Regenerative process is disorganized, resulting in abnormal blood vessel and bile duct relationships from fibrosis
4
Description Normal lobular structure distorted by fibrotic connective tissue Lobules are irregular in size and shape with impaired vascular flow Insidious, prolonged course Normal lobular structure distorted by fibrotic connective tissue Lobules are irregular in size and shape with impaired vascular flow Insidious, prolonged course
5
Statistics > 50% of liver disease in the US is directly related to alcohol consumption Of the estimated 15 million alcoholics in the USA 10-20% have or will develop cirrhosis > 50% of liver disease in the US is directly related to alcohol consumption Of the estimated 15 million alcoholics in the USA 10-20% have or will develop cirrhosis
6
Statistics Growing number of cases related to chronic hepatitis C 4th leading cause of death in people between 35 and 54 years of age Growing number of cases related to chronic hepatitis C 4th leading cause of death in people between 35 and 54 years of age
7
Statistics Direct correlation between alcohol consumption in any geographic area and the death rate from cirrhosis in that area
8
Etiology and Pathophysiology Cell necrosis occurs Destroyed liver cells are replaced by scar tissue Normal architecture becomes nodular Cell necrosis occurs Destroyed liver cells are replaced by scar tissue Normal architecture becomes nodular
9
Etiology and Pathophysiology Four types of cirrhosis: –Alcoholic (Laennec’s) cirrhosis –Postnecrotic cirrhosis –Biliary cirrhosis –Cardiac cirrhosis Four types of cirrhosis: –Alcoholic (Laennec’s) cirrhosis –Postnecrotic cirrhosis –Biliary cirrhosis –Cardiac cirrhosis
10
Etiology and Pathophysiology Alcoholic (Laennec’s) Cirrhosis –Associated with alcohol abuse –Preceded by a theoretically reversible fatty infiltration of the liver cells –Widespread scar formation Alcoholic (Laennec’s) Cirrhosis –Associated with alcohol abuse –Preceded by a theoretically reversible fatty infiltration of the liver cells –Widespread scar formation
11
Etiology and Pathophysiology Postnecrotic Cirrhosis –Complication of toxic or viral hepatitis –Accounts for 20% of the cases of cirrhosis –Broad bands of scar tissue form within the liver Postnecrotic Cirrhosis –Complication of toxic or viral hepatitis –Accounts for 20% of the cases of cirrhosis –Broad bands of scar tissue form within the liver

Manifestations of Liver Cirrhosis Fig. 42-5
15
Clinical Manifestations Early Manifestations Onset usually insidious GI disturbances: –Anorexia –Dyspepsia –Flatulence –N-V, change in bowel habits Onset usually insidious GI disturbances: –Anorexia –Dyspepsia –Flatulence –N-V, change in bowel habits
16
Clinical Manifestations Early Manifestations Abdominal pain Fever Lassitude Weight loss Enlarged liver or spleen Abdominal pain Fever Lassitude Weight loss Enlarged liver or spleen
17
Clinical Manifestations Late Manifestations Two causative mechanisms –Hepatocellular failure –Portal hypertension Two causative mechanisms –Hepatocellular failure –Portal hypertension
18
Clinical Manifestations Jaundice Occurs because of insufficient conjugation of bilirubin by the liver cells, and local obstruction of biliary ducts by scarring and regenerating tissue
19
Clinical Manifestations Jaundice Intermittent jaundice is characteristic of biliary cirrhosis Late stages of cirrhosis the patient will usually be jaundiced Intermittent jaundice is characteristic of biliary cirrhosis Late stages of cirrhosis the patient will usually be jaundiced
20
Clinical Manifestations Skin Spider angiomas (telangiectasia, spider nevi) Palmar erythema Spider angiomas (telangiectasia, spider nevi) Palmar erythema
21
Clinical Manifestations Endocrine Disturbances Steroid hormones of the adrenal cortex (aldosterone), testes, and ovaries are metabolized and inactivated by the normal liver
22
Clinical Manifestations Endocrine Disturbances Alteration in hair distribution –Decreased amount of pubic hair –Axillary and pectoral alopecia Alteration in hair distribution –Decreased amount of pubic hair –Axillary and pectoral alopecia
23
Clinical Manifestations Hematologic Disorders Bleeding tendencies as a result of decreased production of hepatic clotting factors (II, VII, IX, and X)
24
Clinical Manifestations Hematologic Disorders Anemia, leukopenia, and thrombocytopenia are believed to be result of hypersplenism
25
Clinical Manifestations Peripheral Neuropathy Dietary deficiencies of thiamine, folic acid, and vitamin B 12
26
Complications Portal hypertension and esophageal varices Peripheral edema and ascites Hepatic encephalopathy Fetor hepaticus Portal hypertension and esophageal varices Peripheral edema and ascites Hepatic encephalopathy Fetor hepaticus
27
Complications Portal Hypertension Characterized by: –Increased venous pressure in portal circulation –Splenomegaly –Esophageal varices –Systemic hypertension Characterized by: –Increased venous pressure in portal circulation –Splenomegaly –Esophageal varices –Systemic hypertension
28
Complications Portal Hypertension Primary mechanism is the increased resistance to blood flow through the liver
29
Complications Portal Hypertension Splenomegaly Back pressure caused by portal hypertension chronic passive congestion as a result of increased pressure in the splenic vein
30
Complications Portal Hypertension Esophageal Varices Increased blood flow through the portal system results in dilation and enlargement of the plexus veins of the esophagus and produces varices
31
Complications Portal Hypertension Esophageal Varices Varices have fragile vessel walls which bleed easily
32
Complications Portal Hypertension Internal Hemorrhoids Occurs because of the dilation of the mesenteric veins and rectal veins
33
Complications Portal Hypertension Caput Medusae Collateral circulation involves the superficial veins of the abdominal wall leading to the development of dilated veins around the umbilicus
34
Complications Peripheral Edema and Ascites Ascites: - - Intraperitoneal accumulation of watery fluid containing small amounts of protein Ascites: - - Intraperitoneal accumulation of watery fluid containing small amounts of protein
35
Complications Peripheral Edema and Ascites Factors involved in the pathogenesis of ascites: - -Hypoalbuminemia - - Levels of aldosterone - - Portal hypertension Factors involved in the pathogenesis of ascites: - -Hypoalbuminemia - - Levels of aldosterone - - Portal hypertension
36
Complications Hepatic Encephalopathy Liver damage causes blood to enter systemic circulation without liver detoxification
37
Complications Hepatic Encephalopathy Main pathogenic toxin is NH 3 although other etiological factors have been identified Frequently a terminal complication Main pathogenic toxin is NH 3 although other etiological factors have been identified Frequently a terminal complication
38
Complications Fetor Hepaticus Musty, sweetish odor detected on the patient’s breath From accumulation of digested by- products Musty, sweetish odor detected on the patient’s breath From accumulation of digested by- products

Drug Therapy There is no specific drug therapy for cirrhosis Drugs are used to treat symptoms and complications of advanced liver disease There is no specific drug therapy for cirrhosis Drugs are used to treat symptoms and complications of advanced liver disease
53
Nutritional Therapy Diet for patient without complications: –High in calories – CHO –Moderate to low fat –Amount of protein varies with degree of liver damage Diet for patient without complications: –High in calories – CHO –Moderate to low fat –Amount of protein varies with degree of liver damage
