TOPIC - LIVER ABSCESS

REPRESENTED TO RESPECTED Mrs. ANAMIKA SINGH Mam

INTRODUCTION

LIVER ABSCESS IS ALOCAL ACCUMULATION OF PUSH FILLED CAVITY

WITHIN THE LIVER. THE ABCESS CAUSES AN INCREASE OF PRESSURE

WITHIN THE LIVER AS WELL AS A KILLING OF HEALTHY SURROUNDING

LIVER TISSUE. THE END RESULT CAN BE THAT AND OVERWHELMING

INFECT CAN SUDDNELY GAIN ENTANCE INTO THE BLOOD STREAM AT

WHICH POINT THE PATIENT GET EXTREAMLY SICK WITH BLOOD

POISONING.

ABCESS IS

ACOLLECTION OF PUS THAT COLLECTS IN A CAVITY FORMED BY THE

TISSUE MAINLY CAUSED BY BACTERIA OR PARASITESOR BY THE USE OF

NEEDLES , SPLINTERS.

DEFINATION- A liver abscess is a collection of pus in the liver caused by bacteria, fungai or parasites. or

● PYOGENIC LIVER ABSCESS

Pyogenic liver abscess is a pus-filled pocket of fluid within the liver. Pyogenic means "with pus". A liver abscess can develop from several different sources, including a blood infection, an abdominal infection, or an abdominal injury which has been become infected.

● AMOEBIC LIVER ABSCESS

Amebic liver abscess is the most common extra-intestinal manifestation of the protozoan, Entamoeba histolytica. The life cycle involves consumption of fecally contaminated food and water, that reaches and penetrates the small intestine to enter the mesenteric vessels and finally the liver.

CAUSES AND RISK FACTORS

There are many potential causes of liver abscesses, including:

● Abdominal infection such as appendicitis, diverticulitis, ora perforated bowel. ● Infection in the blood. ● Infection of the bile draining tubes. ● Recent endoscopy of the bile draining tubes. ● Trauma that darmages the liver. ● Amebic dysentery. ● Immune deficiency. ● Metastatic liver cancer. ● Endocarditis. ● gallbladder stones.

PATHOPHYSIOLOGY

Due to etiological factors infection develops along the biliary and GI tract.

Infecting organisms may reach the liver through the biliary system, portal venous system and/or hepatic arterial or lymphatic system.

Bacterial toxins destroy the neighbouring liver cells and resulting , necrotic tissue serves as a protective wall for the organisms.

Leukocytes migrate into the infected area. Abscess cavity full of liquid containing living and dead leukocytes, liquefied liver cells and bacteria.

LIVER ABSCESS

DIAGNSTIC EVALUATIONS

● History collection. ● physical examination. ● Abdominal CT scan. ● Abdominal ultrasound. ● Bilirubin blood test. ● Blood culture for bacteria. ● Complete blood count (CBC). ● Liver biopsy. ● Liver function tests. ● White blood cell count.

TREATMENT

● Medician can help treat an infection caused by bacteria , a fungas ,or a parasite. ● Needle aspiration is a procedure to drain fluid with a needle. ● Catheter draining is a procedure to through a catheter inserted into an incision. ● Surgery may be needed if the abscess is large or bursts.

PREVENTION OF LIVER ABSCESS

• Immediate treatment for intraabdominalinfection is the best

prevention measure for liver abscess.

-Four to six week of antisep biatic thearapy postdrainage can prevent

almost any complicatins.

-Direct patient and public education about sanitary measures.

-presonal hygiene , hard washing and food hygiene.

-Boiling of water for consumption.

COMPLICATIONS-

● Biliary tract infection chalangitis in biliary. ● Obstruction ,acute chalecystities. ● Diverticultis, appendicitis. ● Endocardities, bloodstream infection. ● Trouma. ● Postoperative conditions.
