Background/aim: To investigate the geographic occurrence of mucosa-invading Fusobacteria in acute appendicitis.
Patients And Methods: Carnoy- and formalin-fixated appendices from Germany, Russia, and China were comparatively investigated. Bacteria were detected using fluorescent in situ hybridization. Cecal biopsies from patients with inflammatory bowel disease and other conditions were used as disease controls.
Results: Fusobacteria represented mainly by Fusobacterium nucleatum were the major invasive component in bacterial infiltrates in acute appendicitis but were completely absent in controls. The occurrence of invasive Fusobacteria in Germany, Russia, and China was the same. The detection rate in Carnoy-fixated material was 70-71% and in formalin-fixated material was 30-36%.
Conclusions: Acute appendicitis is a polymicrobial infectious disease in which F. nucleatum and other Fusobacteria play a key role.

Introduction: Up to one-third of pediatric patients with acute appendicitis present with radiological evidence of appendicoliths. However, whether appendicolith presence influences prognosis under conservative management compared to non-appendicolith appendicitis remains uncertain.
Methods: We systematically searched PubMed, Cochrane, Embase, and Web of Science databases for studies comparing pediatric appendicolith and non-appendicolith appendicitis managed conservatively with antibiotics, fluids, and percutaneous drainage.

Purpose: Guidelines for management and treatment of appendicitis recommends the removal of a normal-looking appendix, but the recommendations are deemed as weak because they are based on low quality evidence. We aimed to provide an overview of the recommendations from the European societies or associations of surgeons regarding the treatment of acute appendicitis and especially recommendations for the macroscopically normal-looking appendix.
Methods: European surgical societies were contacted and sent an electronic questionnaire.
