Claus Anders Bertelsen is a Clinical Associate Professor at the Department of Clinical Medicine, Faculty of Health and Medical Sciences, University of Copenhagen. Based at Blegdamsvej 3 in Copenhagen, he maintains an active research profile in surgical medicine with particular focus on colorectal surgery, minimally invasive techniques, and perioperative care. His clinical academic position indicates integration of research, teaching, and surgical practice within the Danish healthcare system.

Dr. Bertelsen's research spans multiple critical areas in surgical medicine, with emphasis on improving surgical outcomes through evidence-based approaches. His work investigates pain management strategies including abdominal field blocks and transversus abdominis plane blocks, aiming to optimize analgesia after colon surgery. He also studies hernia repair techniques, colon cancer segmentation standardization, and the use of imaging to predict surgical outcomes. His research employs rigorous methodologies including randomized controlled trials, national registry studies, and Delphi consensus approaches to establish best practices in surgical care.

His recent publications (2024-2025) demonstrate a cohesive research program focused on surgical innovation and standardization. These works span colorectal surgery, hernia repair, pain management, and surgical oncology, often involving multicenter collaborations across Denmark and internationally. The research shows particular strength in methodological diversity, combining clinical trials with consensus building to address critical challenges in surgical practice.

Dr. Bertelsen actively collaborates with surgical teams across Denmark and internationally, as evidenced by his involvement in the Danish Colorectal Cancer Group and the OPMICS Study Group. His work with international consortia indicates strong collaborative networks focused on improving surgical standards and patient outcomes through evidence-based research. His participation in Delphi consensus studies demonstrates recognition as an expert in his field, contributing to the standardization of surgical practices globally.
