Pharyngeal coordination, sphincter opening, and flow pressures during swallowing were investigated in patients with pharyngeal (Zenker's) diverticula. Fourteen patients with diverticula and 9 healthy age-matched controls were studied using simultaneo

In this study, we evaluated the mechanism of action whereby cholecystokinin increases spike-burst rate of the opossum sphincter of Oddi (SO). Each spike burst corresponds to a peristaltic SO contraction. Two types of animal preparations were evaluate

In conscious opossums, we evaluated the relationship between hepatic bile flow and the intestinal motor function during fasting as well as after feeding. In six opossums, bipolar electrodes were implanted from the gastric antrum to the terminal ileum

The reproduction of a patient's biliary-type pain upon initial injection of contrast material into the common bile duct during diagnostic ERCP is a dramatic experience for both patient and physician. The significance of this phenomenon is not clear,

The present study evaluated the mechanism of cholecystokinin-induced gallbladder contraction in awake opossums. Each of 19 chronic animal preparations had an indwelling gallbladder cannula for monitoring changes in gallbladder volume and a jugular ca

In this study, we evaluated the effect of transsphincteric fluid flow on the rate of spike bursts in the opossum sphincter of Oddi (SO). For chronic studies in awake animals, bipolar electrodes were implanted on the SO, gastric antrum, duodenum, and

In this study we recorded intraluminal pressure from the human sphincter of Oddi during ERCP examination and determined the effect of enteric hormones on sphincter of Oddi motor function. Studies were obtained in 26 patients who had no demonstrable e

A recent study in cats suggests that cholecystokinin-octapeptide relaxes the feline lower esophageal sphincter (LES) by evoking an indirect neural inhibitory effect that overrides a direct excitatory myogenic effect. We reasoned that, if cholecystoki

In this study we evaluated the effect of enteric hormones on sphincter of Oddi and gastrointestinal spike burst frequency in fasted conscious opossums. A chronic model for obtaining multiple long-term recordings of sphincter of Oddi and gastrointesti

Phasic pressure waves have been recorded previously from the human sphincter of Oddi during endoscopic retrograde cholangiographic examination. However, the relationship of these waves to each other along the entire length of the sphincter of Oddi se
