Pressure dynamics of the esophagogastric junction at rest and during inspiratory maneuvers after Nissen fundoplication.

Low sphincter pressure and inability of the crural diaphragm to elevate it at the esophagogastric junction are important pathophysiological mechanisms of gastroesophageal reflux disease (GERD). The object of this study was to depict how Nissen fundoplication changed the resting and inspiratory pressures of the anti-reflux barrier. We selected 14 patients (eight males; mean age 42.

Temporal trends and spatial clusters of gastric cancer mortality in Brazil.
