Pathophysiology and management of post resection liver failure
Acta Chirurgica Belgica
|June 20, 2014
Summary
Post resection liver failure (PRLF) can occur after liver surgery, leading to severe complications. Minimizing liver damage during and after resection is key to preventing this critical condition.
Area of Science:
- Hepatobiliary Surgery
- Gastroenterology
- Surgical Pathology
Background:
- Post resection liver failure (PRLF) is a serious complication following liver resection.
- PRLF is characterized by jaundice, coagulopathy, and encephalopathy, carrying high morbidity and mortality rates.
- The incidence of PRLF varies significantly, ranging from 0% to 30%.
Purpose of the Study:
- To define the critical factors necessary for adequate liver remnant regeneration.
- To identify strategies for preventing post resection liver failure.
- To highlight the importance of avoiding ongoing parenchymal damage post-resection.
Main Methods:
- This study reviews the physiological requirements for liver regeneration.
- It examines factors contributing to liver remnant viability.
- Strategies for minimizing complications post-liver resection are discussed.
Main Results:
- Adequate regeneration requires sufficient hepatocytes and nonparenchymal cells.
- A normal functional and regenerative capacity of the liver remnant is essential.
- Effective accommodation of hemodynamic changes without congestion is crucial for preventing PRLF.
Conclusions:
- Avoiding ongoing parenchymal damage post-liver resection is paramount to prevent PRLF.
- Minimizing ischemia reperfusion injury is a key preventive strategy.
- Prompt treatment of infection/sepsis and avoidance of small for size syndrome are critical for patient outcomes.

01:24Cirrhosis II: Pathophysiology
34
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...

880
Esophageal varices often manifest as gastrointestinal bleeding episodes, presenting symptoms like hematemesis (vomiting of blood), hematochezia (passing fresh blood via the rectum), and melena (black, tarry stools). Other signs can include weight loss, anorexia, abdominal discomfort, jaundice, pruritus, altered mental status, and muscle cramps.

01:26Effect of Hepatic Disease on Pharmacokinetics: Drug Dosing and Hepatic Blood Flow
380
Chronic liver disease significantly impacts drug metabolism due to alterations in hepatic blood flow and enzyme accessibility. This disruption affects the body's pharmacokinetics—the movement and processing of drugs within the system. Key enzymes crucial for metabolizing medications become less accessible, changing how drugs are processed and utilized. Furthermore, liver disease influences the synthesis of plasma proteins, such as albumin and globulins, which play critical roles in drug...

01:24Liver Regeneration
4.1K
The liver is an important organ in vertebrates that plays an essential role in metabolism. It is also responsible for storing and redistributing nutrients such as carbohydrates, fats, and vitamins in the body. Additionally, the liver releases bile salts which are critical for digesting food and eliminating toxic metabolites from the body.

In clinical practice, the direct measurement of hepatic blood flow to evaluate liver function presents significant challenges due to the intricate and specialized nature of the necessary techniques. Consequently, healthcare professionals often rely on empirical estimates derived from thorough patient examinations and liver function tests to gauge liver health. Among the tools at their disposal, the Child–Pugh and MELD scoring systems stand out for their ability to categorize and assess...
