title: Gastrointestinal motility and neurogastroenterology.
abstract: Nordic research on gastrointestinal motility has since 1965 made substantial contributions to our current understanding of gastrointestinal function. During the last decade, the term neurogastroenterology has widened the concept of motility research into the study of gastrointestinal sensory-motor function, including the complex central nervous system interaction. The discovery of a non-adrenergic non-cholinergic (NANC) innervation of the gut in the sixties was made by considerable contributions from the Nordic countries with the Martinson group in Sweden as central innovators. Important discoveries regarding the intramural nerve ganglia as mediators of the autonomic nervous input has also been produced from this research. In clinical motility research, the study of the migrating motor complex in the small bowel has revealed its ability to act as a retroperistaltic pump in the proximal duodenum (Sweden) and its important role for gut microbial homeostasis (Norway). Also in the development of methodology to study gut sensory-motor function, the Nordic countries has contributed. Examples are the physical characteristics of the esophageal manometry catheter (Denmark), the use of ultrasound for assessment of gastric function (Norway), a temporary electrical stimulation method in patients with severe nausea and vomiting (Sweden), a rectal barostat method for clinical evaluation of recto-anal function and a colonic transit time method utilizing radio-opaque markers (Sweden). In later years, the research collaborations have increasingly become worldwide in a manner making it less easy to define pure Nordic contributions.
