Analysis of single-peaked pressure profile in hiatus hernia and controls: positions of SCJ, pH transition point and peak LOS pressure relative to nares and to upper border LOS
| Hiatus hernia | Controls | p Value | |
|---|---|---|---|
| Nares to upper border LOS (cm) | 44.5 (4.13) | 44.5 (3.5) | 0.184 |
| Nares to SCJ (cm) | 46.1 (4.76) | 47.2 (3.99) | 0.010 |
| Nares to pH transition point (cm) | 45.6 (7.10) | 48.5 (6.33) | 0.004 |
| Upper border LOS to pH transition point (cm) | 2.2 (4.28) | 2.5 (2.85) | 0.011 |
| Upper border LOS to SCJ (cm) | 1.99 (2.63) | 2.34 (1.65) | 0.081 |
| Peak LOS pressure to pH transition point (cm) | −0.5 (4.60) | 0.8 (2.95) | 0.003 |
Results presented as median (IQR).
LOS, lower oesophageal sphincter; SCJ, squamocolumnar junction.
