摘要: Abstract Objectives: This study compared the pressure topography after laparoscopic Nissen fundoplication to that of normal subjects and patients with hiatal hernia reflux disease. Methods: Seven fundoplication, 7 hernia, were studied. The squamocolumnar junction intragastric margin esophagogastric (EGJ) marked metal clips. Axial radial characteristics EGJ mapped relative clipped during concurrent fluoroscopy manometry. Responses inspiration abdominal compression also analyzed. Results: Fundoplication modifies by restoration component elongation subdiaphragmatic component. Maximal is mainly dependent on extrinsic effect canal compresses esophagus; resultant length reflects fundic wrap. Integrity independent intrinsic lower esophageal sphincter itself. Conclusions: alters reducing tightening orifice, constructing a wrap variable length. Each depends different technical aspects surgery potential substantial variability in topography.
