High Resolution Manometry Guidance During Laparoscopic Fundoplication in Pediatric Surgically “Fragile” Patients: Preliminary Report

“…With HRM, which does not necessitate the pull through maneuver of the catheter, we get a complete spatial and temporal view of esophageal motor function, by converting the pressure data into a color topographical map. A pressure profile of the entire esophagus and sphincters can be simultaneously viewed in real time from the pharynx to the stomach with UES; while EGJ easily identifies zones of high pressure that are depicted as horizontal bands of warmer color [6][7][8][9][10][11][12][13]. Even though no reference values with HRM are available in pediatric "fragile" patients, the experience in the adults [32] may support the role of this approach to optimize the antireflux surgery outcome in children [29][30][31].…”

“…Solid-state high-resolution manometry (HRM), with a series of closely spaced pressure sensors, [6][7][8][9][10][11][12][13], has been recently introduced in clinical practice to detect esophageal intraluminal pressures at different esophageal sites including the esophagogastric junction (EGJ). HRM also helps the surgeon evaluate esophageal motor function in pediatric congenital and acquired esophageal motility disorders [14][15][16][17][18].…”
