Gastroesophageal reflux in cirrhotic patients without esophageal varices

Table 1 Results of esophageal manometry in liver cirrhosis patients and controls (mean ± SD)

Group	LESP (mmHg)	PA (mmHg)	PD (s)	PV (cm/s)
Liver cirrhosis (n = 78)	15.32 ± 2.91a	61.41 ± 10.52a	5.32 ± 1.22a	5.22 ± 1.11a
Child A (n = 28)	16.18 ± 2.81	70.52 ± 8.93a	3.91 ± 1.03a	4.56 ± 1.22a
Child B (n = 27)	15.41 ± 3.13c	67.4 ± 9.3c	5.11 ± 1.21c	5.10 ± 1.02c
Child C (n = 23)	14.52 ± 2.91e	56.13 ± 10.06e	6.02 ± 1.23e	5.91 ± 1.01e
Control (n =30)	16.21 ± 5.33	74.41 ± 17.53	2.70 ± 0.81	3.71 ± 1.82

^aCompared with control, P < 0.05;

^cCompared with Child A, P < 0.05;

^eCompared with Child B, P < 0.05. LESP: Lower esophageal sphincter pressure; PA: Peristaltic amplitude; PD: Peristaltic duration; PV: Peristaltic velocity.
