Diseases of the Liver and Gallbladder01:26

Diseases of the Liver and Gallbladder

Liver and gallbladder diseases are a significant health concern, with prominent conditions including cirrhosis, hepatitis, non-alcoholic fatty liver disease (NAFLD), and gallstones. Jaundice is a common manifestation of liver and biliary disease.
Cirrhosis is characterized by the scarring of hepatic lobules in the liver, which are replaced by fibrous tissue, affecting the liver's normal functioning. NAFLD, on the other hand, is caused by an excessive build-up of fat in the liver, not related to...
Portal Hypertension01:22

Portal Hypertension

Portal hypertension is an increase in blood pressure within the portal venous system. Normally, this pressure is less than 5 mmHg. It is considered clinically significant when it rises above 10 mmHg. At this threshold, complications from altered blood flow and venous congestion emerge.EtiologyPortal hypertension arises from conditions that impede blood flow through the liver. The most common cause is cirrhosis, in which chronic liver injury leads to fibrotic scarring. This fibrosis narrows or...
Hepatic Encephalopathy01:29

Hepatic Encephalopathy

DefinitionHepatic encephalopathy is a reversible neurologic syndrome that results from advanced liver dysfunction or portosystemic shunting. It leads to disturbances in cognition, behavior, and motor function due to the brain’s exposure to gut-derived toxins that the liver fails to detoxify.EtiologyThis condition develops either in the setting of acute fulminant hepatitis or progressively during chronic liver disease, such as cirrhosis and portal hypertension. Portosystemic shunting—including...
Cirrhosis II: Pathophysiology01:24

Cirrhosis II: Pathophysiology

Cirrhosis is a progressive chronic liver injury caused by prolonged inflammation, excessive fibrotic remodeling, and impaired regeneration. Over time, repeated hepatic insults disrupt the liver’s architecture and function, leading to reduced blood flow, impaired bile drainage, and diminished metabolic capacity.Pathophysiology of cirrhosisCirrhosis arises from three main responses to chronic liver damage: inflammation, immune activation, and hepatocyte death. These processes lead to structural...
Cirrhosis I: Introduction01:23

Cirrhosis I: Introduction

Cirrhosis is a chronic, irreversible liver disease characterized by the widespread replacement of healthy liver tissue with fibrotic scar tissue and the formation of regenerative nodules.Etiology of cirrhosisCirrhosis results from sustained liver injury that triggers progressive fibrosis and structural remodeling. The underlying causes are diverse, encompassing common and less frequent clinical conditions. Regardless of the origin, all causes lead to chronic inflammation, hepatocyte loss, and...
Hepatitis01:25

Hepatitis

Hepatitis is an inflammatory condition of the liver most commonly caused by hepatotropic viruses (A–E), though non-infectious causes such as alcohol and drugs also exist.Hepatitis AHepatitis A virus (HAV) is a non-enveloped RNA virus of the Picornaviridae family. It is primarily transmitted via the fecal-oral route, typically through ingestion of contaminated food or water. After ingestion, HAV enters the bloodstream through the oropharynx or intestinal epithelium and reaches the liver. The...

    Summary

    Liver echinococcosis is common in Bulgaria, often causing complications that lead to misdiagnosis. Early consideration of hydatid disease and increased ultrasonography use are crucial for accurate diagnosis and treatment.

    Area of Science:

    • Hepatology
    • Infectious Diseases
    • Radiology

    Background:

    • Liver echinococcosis is a prevalent parasitic infection in Bulgaria.
    • Complications such as allergies, portal hypertension, and biliary or neurological issues are frequent.
    • These complications can lead to diagnostic challenges and inappropriate treatments.

    Purpose of the Study:

    • To highlight the diagnostic difficulties associated with complicated liver echinococcosis.
    • To emphasize the importance of including hydatid disease in the differential diagnosis.
    • To advocate for expanded ultrasonography use in suspected cases.

    Main Methods:

    • Review of clinical cases with complicated liver echinococcosis.
    • Analysis of diagnostic pathways and treatment outcomes.

    Application of the En Bloc Concept Combined with Anatomic Resection in Laparoscopic Hepatectomy

    Published on: March 10, 2023

  • Comparison with non-echinococcal liver pathologies.

    • Main Results:

    • Complicated echinococcosis frequently presents with non-specific symptoms, leading to delayed or incorrect diagnoses.
    • Allergic reactions, portal hypertension, and biliary pathology are common complicating factors.
    • Ultrasonography proved effective in identifying hydatid cysts when specifically indicated.

    Conclusions:

    • Hydatid disease should be actively considered in the differential diagnosis of liver pathologies, especially in endemic areas like Bulgaria.
    • Wider application of ultrasonography is recommended for patients with suggestive symptoms or complications.
    • Improved diagnostic strategies are needed to ensure timely and adequate treatment of liver echinococcosis.
