Abstract:
Acute appendicitis remains an up to date issue, being the most frequent cause of surgical acute abdomen round the globe. The complications that occurs creates important therapeutically difficulties. The study, based on 114 cases, had analyzed not only the pathogen flora (type, association, frequency of certain germs, the relation between them and different pathological lesion), but also the immune response of the organism to septic aggression. The microbiological tests from the lumen and bont of the appendix and also from peritoneal cavity showed monobacterial infection (11%) and pluribacterial infection (89%). Association between aerobes and anaerobes germs was identified in 85%. The most frequent germs identified were E. coli (87%) and Bacteroides (55%). We didn't identify germs with particular pathogenesis and the immune response had no malfunction. We can conclude that time factor is the main element in constituting of complications during acute appendicitis. A late diagnosis and also a late surgical intervention are the bases for the gravity of the pathogenic process.
Insights
Delayed diagnosis and treatment of acute appendicitis significantly increase complication risks. Prompt surgical intervention is crucial for better outcomes in this common surgical emergency.
Area of Science:
- Microbiology
- Surgical Pathology
- Immunology
Context:
- Acute appendicitis is a leading cause of acute abdomen globally.
- Complications present significant therapeutic challenges.
- This study analyzed 114 cases of acute appendicitis.
Purpose:
- To investigate the pathogen flora and immune response in acute appendicitis.
- To determine the relationship between microbial findings and pathological lesions.
- To identify factors contributing to complications.
Summary:
- Microbiological analysis revealed predominantly pluribacterial infections (89%), with aerobes and anaerobes frequently associated (85%).
- Escherichia coli (87%) and Bacteroides (55%) were the most common pathogens identified.
- No specific pathogenic germs or immune system malfunctions were found; time to diagnosis and surgery emerged as critical factors for complications.
Impact:
- Highlights the critical role of timely diagnosis and surgical intervention in managing acute appendicitis.
- Provides insights into the polymicrobial nature of appendicitis infections.
- Emphasizes that complications are primarily linked to delays rather than specific microbial virulence or immune deficiency.
