Ten patients were referred to our clinical esophageal laboratory for prolonged pH monitoring to determine whether GE reflux was the cause of chronic cough. In addition, we(More)
Our hypothesis was that rumination syndrome is associated with gastric sensory and motor dysfunction. We studied gastric and somatic sensitivity, reflex relaxation of the lower esophageal sphincter (LES), and gastric compliance and accommodation postprandially and postglucagon. A barostatically controlled gastric bag and esophageal manometry were used to(More)
Our aims were to measure antral axial forces in patients with suspected upper gut dysmotilities and to compare the number of antral contractions detected by an axial force catheter and by manometric sensors in the distal antrum and pylorus. Fifteen patients (2 men, 13 women; mean age 42 years) underwent studies for 3 hr fasting, 2 hr postprandially, and up(More)
