Manka. Impact of fundoplication on bolus transit across esophagogastric junction. Am. J. Physiol. 275 (Gastrointest. Liver Physiol. 38): G1386–G1393, 1998.—This study ana-lyzed the effect of fundoplication on the mechanics of liquid and solid bolus transit across the esophagogastric junction (EGJ). The squamocolumnar junction was endoscopically clipped in seven controls, seven hiatal hernia patients, and seven patients after laparoscopic Nissen fundoplication. Con-current manometry and fluoroscopy were done during swal-lows of liquid barium and a 13-mm-diameter marshmallow. The EGJ opening, pressure gradients, transit efficacy, and axial motion were measured. The axial motion of the EGJ was reduced in the fundoplication and hiatal hernia patients. The opening dimensions at the squamocolumnar junction were similar among groups, but in each case the constrictio
