Gastric emptying and dyspeptic symptoms in the irritable bowel syndrome.

Many patients with irritable bowel syndrome (IBS) have symptoms suggestive of disturbances in gastric emptying, but so far no abnormalities in gastric emptying have been demonstrated in these patients. We studied gastric emptying of a solid meal with a 99mTc-labeled pancake in 16 healthy volunteers (8 women and 8 men; age, 20-33 years; mean age, 25 years) and 16 predominantly constipated IBS patients (10 women and 6 men; age, 17-43 years; mean age, 25 years). The incidence and severity of the symptoms nausea, vomiting, early satiety, and pain in the upper abdomen were scored.

Effects of cisapride, a new gastrointestinal prokinetic substance, on interdigestive and postprandial motor activity of the distal oesophagus in man.

Cisapride is a newly developed substance that stimulates gastrointestinal motility, possibly enhancing acetylcholine release in the gut wall. The aim of our study was to investigate the effect of cisapride on oesophageal motor function in man. In a blind fashion and in random order six healthy volunteers received cisapride (0.
