Cihan Özen

Cihan Özen serves as a Guest researcher and Specialist Doctor (Speciallæge) at Aalborg University Hospital within the Faculty of Medicine's Department of Gastrointestinal Surgery. His clinical-research nexus focuses on optimizing surgical infection management through biomarker-driven clinical decision-making and therapeutic interventions.

Research interests center on Gastrointestinal Surgery and Infectious Complications, with specialized expertise in Inflammatory Biomarkers (particularly procalcitonin), Clinical Severity Assessment for intra-abdominal infections, Antibiotic Therapy protocols for appendicitis and acute abdomen, and Interventional Radiology techniques for gastrointestinal bleeding. His work bridges laboratory biomarker analysis with real-world surgical outcomes.

Analysis of 2023-2025 publications reveals three dominant research trajectories: 1) Biomarker validation for infection severity grading (procalcitonin vs conventional markers), 2) Antibiotic regimen optimization for postoperative complications, and 3) Interventional radiology safety/efficacy in peptic ulcer bleeding. Methodologically, his team employs retrospective cohort studies and single-center clinical evaluations published in surgical journals like Langenbeck's Archives of Surgery.
