Liver. Anatomical and morphological features. The
structure of the liver lobule
Cirrhosis of the liver. Definition
Diffuse pathological process,
accompanied by a violation of the
normal architectonics of the organ,
the formation of nodes of the
regeneration of the parenchyma,
fibrous septa, leading to the
restructuring of the vascular system
of the liver
Cirrhosis of the liver. Relevance
ей органов пищеварения.
About 700 thousand annually – die
from cirrhosis of the liver
Liver cirrhosis and fibrhosis are the
cause of 90-95% of chronic liver
disease deaths
Etiology.
polyetiological disease, but the main causes are
Viruses: HBV, HCV, HDV
B. Alcohol
B. Other factors: drugs, autoimmune
mechanisms (CAH), metabolic diseases
(hemochromatosis, Konovalov-Wilson's disease,
etc.) occupy a small proportion in the etiology
cryptogenic - the cause is not established in
about 10-20% of cases
Etiology of cirrhosis. Alcohol
The causes of cirrhosis are
Acute alcoholic hepatitis
Alcoholic steatohepatosis
It develops in 15-20% of people who
have consumed 60-80g of ethanol in
men and 40-50g of ethanol in women
daily or often for many years
Typical

Histological changes in the liver parenchyma with
cirrhosis
Pathogenesis of cyrrhosis
Viruses. alc. etc
Necrosis of hepatocytes
Neo Fibrillogenesis
Violation of the liver
architectonics
Pathogenesis
Neofibrillogenesis (function of
perisinusoidal cells of the ITO) is an excess
fibroplastic process: nodulation, formation
of connective tissue septa connecting the
central veins and portal tracts,
fragmentation of the hepatic lobules into
false.
Anastomoses bypass blood
Pathogenesis of C. Anastomoses bypass
blood
Pathogenesis
Blood bypass by anastomoses leads to
ischemia and necrosis of hepatocytes
Hepatocyte breakdown products stimulate
regenerative processes - neofibrillogenesis
A vicious circle is formed, the structure
and functions of the liver are disrupted,
portal hypertension develops
Classification of cirrhosis of the liver.
According to morphological characteristics
Micronodular, or small-knot
(regeneration nodes up to 3 mm) (in the
etiology of alcohol or chronic hepatitis
C)
Macronodular, coarse (nodes over 3
mm) (more often the outcome of viral
hepatitis B and autoimmune hepatitis)
Mixed (both types of nodes are present,
more often hepatitis B + C, viruses +
alcohol)
Stage: initial, severe clinical
manifestations, terminal
Phase:
active (minimal, moderate, high),
inactive
The degree of functional impairment:
light, medium, heavy
Classification of cirrhosis
According to clinical characteristics
Classification of cirrhosis of the liver. Clinical
manifestations
The severity of portal hypertension:
hidden, moderate, pronounced; subhepatic,
intra-, suprahepatic, mixed
The presence of syndromes:
hepatolienal, hepatorenal, hepatopancreatic
Complications:
edematous ascites syndrome, hemorrhagic
syndrome, hypersplenism, hepatic
encephalopathy (coma)
Clinic of cirrhosis
Hepatitis syndromes (cytolytic,
mesenchymal-inflammatory,
cholestatic, hemorrhagic, dyspeptic,
asthenovegetative) persist, but their
severity changes (more or less)
New cirrhosis specific syndromes
appear
Clinic. Nonspecific syndromes
There is a decrease in the manifestations of the
cytolytic syndrome (viral activity decreases)
An increase in cholestatic syndrome (a change
in the architectonics and function of
hepatocytes)
- An increase in hemorrhagic (portal
hypertension and impaired blood formation),
It is possible to attach a pain syndrome (severe
hepatomegaly, spasm, dysgenia, peritonitis,
ischemia, portal vein thrombosis, intense
ascites)
Clinic. Specific syndromes
Portal hypertension: port-caval and other
anastomoses, varicose veins of the
esophagus, stomach, rectum, ascites,
anasarca,
Hepatomegaly (in the late stages,
reduction in size) - in 80-90% of patients
and liver compaction
Clinic of cirrhosis of the liver. Specific
syndromes
Hepatocyte deficiency syndrome:
violation of protein-synthetic, detoxification,
hormone-synthetic, hemostatic, digestive and
other functions. It manifests itself in weight loss
in patients with manifestations of protein, fatty
degeneration, gynecomastia in men,
telangiectasias, palmar erythema, hemorrhagic
manifestations, disturbances in the nervous
system, changes in hematopoiesis, etc.
Clinic. Specific syndromes
Splenomegaly (portal hypertension),
which turns into hypersplenism
(impaired hematopoietic function of
the spleen)
Hepatorenal, hepatopancreatic
syndromes (shunting of the kidneys,
pancreas leads to impaired function)
Clinic. Early reliable signs of cyrrhosis
Teleangiectasias, palmar erythema,
gynecomastia (breast enlargement in
men), hepatomegaly with a
compacted, scalloped edge of the
liver
History of hepatitis, alcoholism,
periodic flatulence, violation of the
color of urine (darkening), feces
(lightening)
Palpation of the liver - the first stage of
diagnosis
Small signs of cirrhosis. Palmar erythema
Small signs of cirrhosis. Spider veins.
Teleangiectasia
Clinic. Late manifestations
Varicose veins, splenomegaly. Ascites,
anasarca, "the head of Medusa."
Trophological insufficiency is a consequence
of a violation of the synthetic function of the
liver, an imbalance in the intake and
consumption of nutrients
Kwashiorkor (protein deficiency in the blood
and internal organs).
Insanity (depletion of the somatic pool of
proteins and fat stores)).
Patient with
portal
hypertension

laparocentesis
Diagnosis of cirrhosis of the liver. Blood
biochemistry. Signs of hepatocellular failure
Decrease in total protein, albumin. The
increase in globulins.
Increase in protein sedimentary samples.
Thymol, sublimate (10 or more times)
Increased levels of blood cholestasis markers
- bilirubin, alkaline phosphatase, GGTP
increase in blood cholinesterase level,
change in bromosulfalein test (delay in its
release of more than 25% at N 5%)
Violation of haemostasis: a decrease in IPT
proportional to the severity, an increase in ,
etc.
Biomarkers in the diagnosis of liver fibrosis
FT (fibrotests - in the blood serum determine the
content
- total bilirubin, GGTP, a2-macroglobulin, apoprotein A1
and haptoglobin
hyaluronic acid
the severity of deviations of indicators characterizes
fibrosis (F2-F4) FT (fibrotests - in the blood serum
determine the content
- total bilirubin, GGTP, a2-macroglobulin, apoprotein A1
and haptoglobin
hyaluronic acid
the severity of deviations of indicators characterizes
fibrosis (F2-F4)
Severe
hepatocellu

(protein-
fat) failure
- cachexia
in a patient
with
cirrhosis
Diagnosis of liver cirrhosis
FGDS (visualization of varicose veins, node sizes),
Ultrasound (determination of the size and structure
of the liver, identification of large regeneration
nodes, hepatosplenomegaly),
CT of the liver and biliary tract and ERCP in the case
of a differential diagnosis of biliary CP,
Liver and spleen scan
Laparoscopy with puncture biopsy of the liver -
verification of the diagnosis
Celiacography (contrast study for vascular
imaging).
Splenoportography is used only in case of an
upcoming shunt operation.
Diagnostics. Dopplerometry,
rheoelastography
changes in the diameter and patency of
blood vessels;
impaired blood flow in the liver
Diagnostics. Scintigraphy (the introduction of a
radioactive substance to assess the functioning of
the liver) is characteristic of:
a decrease in the concentration of a
radioactive element (against the background
of a drop in the ability to capture and hold
such substances);
the substance is not fixed (dysfunction of all
parts of the diseased organ);
the substance is retained in the spleen zone;
the drug settles in the bones of the pelvis and
spine (a critical decrease in liver function)
Diagnostics. MRT
The study of the organ through MRI allows a
qualitative assessment of its anatomy, namely:
parameters relative to the norm, structural
leaving, location, concentration of lesions.
- a significant decrease in the size of the organ
with its partial right-sided atrophy, so
characteristic of cirrhosis, is visible.
allows you to track the pathological changes
occurring in the portal vein, which passes
through the liver and contains the main source of
blood supply to the organ.
CT of the liver in CP
Laparoscopy-verification of the diagnosis
- minimally invasive surgery is necessary for
differential diagnosis. In multi-node cirrhosis,
neoplasms are visible (red or brown in color,
sizes from 3 mm), dilated veins, and
thickening of the hepatic capsule.
Laparoscopic diagnosis is performed to
confirm the diagnosis.
Cirrhosis. Rare form.
Primary biliary
Rare prevalence (25-30 per 1 million population)
Women aged 40 to 60 are more likely to get sick
In pathogenesis, destructive cholangitis, - the
formation of autoantibodies to the mitochondrial
membrane of bile epithelial cells
The main clinical syndrome is cholestatic. Blood
has a high content of cholestasis markers
(bilirubin, schf, GGTP), ALT,
detection of antimitochondrial antibodies during
immunological examination approves the
diagnosis
Cirrhosis. Rare form.
Secondary biliary
ространенность неизвестна
t is always secondary against the background of
long-existing cholestasis in biliary tract
obstruction (GI, calculous cholecystitis, duct
strictures, etc.)
In the clinic, cholestatic syndrome is often
combined with pain (in the right
hypochondrium)
Laboratory markers of cholestasis are positive,
but there are no autoantibodies in the blood
during immunological examination
Additional methods of examination (CT,
ultrasound, ERCP) reveal obstruction of large
bile ducts

Differential diagnosis of C
Different etiology of cirrhosis are differentiated
among themselves, using viral markers and
other tests
Liver tumor Cirrhosis-cancer (malignancy or
primary tumor) using the above criteria and
additional research methods , in this case main
diagnostic value has imm. marker –α fetoprotein
(increased serum level)
It’s worth using the above criteria and additional
research methods
TREATMENT OF LIVER CIRRHOSIS
Etiotropic:
elimination of alcohol;
treatment of viral hepatitis with interferons
and nucleosides, class A (on the child-Pugh
scale), with C of group B,C-is not shown
