Brief Summary
Review the sponsor-provided synopsis that highlights what the study is about and why it is being conducted.
2. To evaluate the management plan and treatment outcome of liver abscess.
3. To study risk factors of liver abscess.
Detailed Description
Dive into the extended narrative that explains the scientific background, objectives, and procedures in greater depth.
The incidence of liver abscess varies from one country to another. The annual incidence of pyogenic liver abscess has been estimated at 2.3 cases per 100,000 populations and 18-20 per 100 000 hospital admissions (Mohsen et al 2002, Kaplan et al 2004).
Liver abscess is a potentially life-threatening condition (Ahmed et al., 2016).
A review by Chan KS et al. of 16 pyogenic LA (PLA) articles showed mortality rates ranging from 0% to 15.7 % (Chan et al., 2022).
The etiology of LA can be bacterial (most often polymicrobial), parasitic (amebic essentially), mixed (pyogenic superinfection of parasitic abscess) or more rarely fungal (Nakanishi et al., 2009).
Microbes can invade the liver parenchyma by way of the bile ducts, blood stream (hematogenic, most often portal), or by contiguous spread, especially via the gallbladder bed (Yoo et al., 1993, Thomsen et al., 2007).
Advanced age, diabetes mellitus (DM) and the presence of underlying malignancy are considered major risk factors, and the latter is associated with a worse prognosis (Yoo et al., 1993, Thomsen et al., 2007).
The number of cryptogenic liver abscess cases has been on the rise, and no predisposing conditions (cryptogenic) was reported in 18% (McNeil et al. 2020).
The diagnosis of LA relies essentially on imaging. Sonography and CT scan lead to diagnosis in more than 90% of cases (Halvorsen et al., 1984).
