Main research topic is the enteric nervous system (ENS). The ENS ("little brain of the gut") represents the largest nervous system outside the central nervous system that controls the peristaltic movements and many other functions (e.g. resorption, secretion, immune defense) of the gastrointestinal tract.
Our investigations on development, structural organization and functions of the ENS contribute to unravel the origin of severe gastrointestinal motility disorders.
Special emphasis is given to the histopathological diagnosis of enteric neuropathies and myopathies underlying various functional gastrointestinal disorders (e.g. slow-transit constipation, megacolon, chronic intestinal pseudoobstruction, irritable bowel syndrome, diverticular disease).
Our research group is member of an international working group establishing guidelines for histological techniques and reporting on gastrointestinal neuromuscular pathologies.
The interdisciplinary research approaches involve both clinical and basic science projects.

Scientific Societies

The German Society for Neurogastroenterology and Motility offers the possibility to exchange and distribute medical, diagnostic and therapeutic as well as scientific results and informations in the field of neurogastroenterology and motility. Our research group is actively involved in the society (member of the executive board, 2006-2008).

We have contributed to the following guidelines on behalf of the German Society of Digestive and Metabolic Diseases (DGVS):

  • Irritable bowel syndrome
  • Intestinal motility disorders
  • Constipation
  • Diverticular disease

Clinical Anatomy

Main purpose of clinical anatomy is to focus on those anatomical structures which are required for the understanding and successful application of surgical procedures and special surgical instruments, devices and materials.
Anatomical specimens are treated by different dissection techniques to allow the testing of surgical instruments and implants and the training of innovative surgical procedures.
The scientific projects, hands-on workshops and postgraduate educational courses for medical doctors and medical technology companies are organized by the Center of Clinical Anatomy.
