In above-average risk individuals undergoing colonoscopy-based surveillance for colorectal cancer (CRC), screening with fecal immunochemical tests (FIT) between colonoscopies might facilitate personalization of surveillance intervals. Since a negativ

Integration of canine proximal gastric, antral, pyloric, and proximal duodenal motility during fasting and after a liquid meal

Autor: Keith A. Kelly, Brent W. Miedema, Richard Heddle

Publikováno v: Digestive Diseases and Sciences. 38:856-869

The aim was to investigate the integration of proximal gastric, antral, pyloric, and duodenal motility during fasting and after feeding. Using a proximal gastric barostat and a manometric assembly with an array of side holes astride the gastroduodena

The aim was to determine the effect of intraluminal acetic acid and proximal colonic distension on canine ileocolonic sphincter pressure, ileal motility, and coloileal reflux. In six conscious dogs with an isolated ileocolonic loop, basal pressure of
