Pyogenic Liver Abcess in Guadeloupe

Liver abscesses are infections of the liver parenchyma, most often bacterial, occurring via the biliary tract, bloodstream, or by direct spread. Although rare, they are serious, with a mortality rate of around 15%. In Western countries, they are mainly polymicrobial or associated with Escherichia coli, streptococci, and Klebsiella pneumoniae. While overall incidence is low, it appears higher in Guadeloupe. There is a growing increase in cases caused by hypervirulent \*Klebsiella pneumoniae\* (hvKp), which can infect healthy individuals and spread to distant sites such as the eye, lungs, and central nervous system. Its virulence is linked to specific genetic factors. The emergence of multidrug-resistant hypervirulent strains represents a major concern. In Guadeloupe, about ten cases per year are reported, with no clearly identified risk factors.

Laparoscopic Approach to Pyogenic Liver Abscess

Assess the efficacy and safety of laparoscopic management of liver abscess in achieving complete drainage and clinical recovery compared to conventional open or percutaneous methods, and to: 1. To evaluate postoperative complications and recurrence rates. 2. To compare hospital stay, recovery time, and overall morbidity. 3. To determine patient outcomes and cost-effectiveness of laparoscopic intervention.
