Niels Qvist

Niels Qvist is a Professor at the Clinical Institute of the University of Southern Denmark, affiliated with Odense University Hospital (OUH) where he works in the Research Unit for Surgery. His academic career spans surgical research with a focus on gastrointestinal procedures and complications, with over 555 publications to his name.

His primary research interests include:

• Postoperative Complications
• Surgical Anastomosis techniques and failures
• Inflammatory Bowel Disease (Ulcerative Colitis and Crohn's Disease)
• Anastomosis Leakage prevention and management
• Cohort Analysis methodologies
• Systematic Reviews in surgical outcomes

Professor Qvist's recent publications (2024-2025) demonstrate a strong focus on gastrointestinal surgery outcomes, inflammatory bowel disease treatments, and surgical complication prevention. His work frequently involves large-scale cohort studies examining drug safety (particularly biologics for IBD), comparative effectiveness of surgical techniques, and innovative approaches to anastomotic perfusion assessment. He often collaborates with multidisciplinary teams across Denmark on clinical trials and observational studies.

His scientific contributions include numerous high-impact publications with notable recent work on:

• Longitudinal safety studies of Golimumab for ulcerative colitis treatment
• Comparative studies of colon capsule versus traditional colonoscopy
• Vacuum-assisted closure techniques for postoperative complications
• Autoimmune comorbidities in pediatric inflammatory bowel disease

Professor Qvist actively supervises students and junior researchers, with multiple guidance relationships documented in animal experimental studies related to surgical techniques and anastomosis. His work bridges clinical practice with surgical research, particularly in gastrointestinal surgery and inflammatory bowel disease management, with strong connections to both clinical care at Odense University Hospital and academic research at the university.
