Esophageal Contractions After Wet and Dry Swallows in Patients With Esophagitis, Chagas' Disease and Idiopathic Achalasia

Figures

Figure 1. Area under the curve (AUC) of the proximal and distal esophageal contractions in patients with esophagitis (n = 28), Chagas’ disease (n = 37), idiopathic achalasia (n = 8), and controls (n = 31). (mean and SEM). *p < 0.02 vs dry, +p < 0.01 vs Chagas and achalasia.

Figure 2. Interval between the upstroke of proximal and distal esophageal contractions in patients with esophagitis (n = 28), Chagas’ disease (n = 37), idiopathic achalasia (n = 8), and controls (n = 31). (mean and SEM). *p < 0.01 vs dry, +p < 0.01 vs Chagas and achalasia, #p < 0.01 vs achalasia.

	Wet	Dry	p	Wet	Dry	p
Esophagitis (n = 28), Idiopathic Achalasia (n = 8), Chagas’ Disease (n = 37), and Controls (n = 31).
The results are reported as mean (SD). ^ap < 0.02 vs esophagitis, Chagas, controls; ^bp < 0.01 vs esophagitis, controls; ^cp < 0.01 vs esophagitis, achalasia, controls
Controls	95.1 (56.0)	78.7 (46.8)	0.22	88.3 (37.2)	45.0 (28.4)	< 0.01
Esophagitis	85.6 (34.6)	75.3 (39.7)	0.30	90.9 (42.2)	44.6 (32.6)	< 0.01
Achalasia	31.4 (11.0)^a	32.4 (18.3)^a	0.90	38.9 (16.0)^b	46.1 (34.0)	0.60
Chagas	75.4 (49.3)	63.8 (40.4)	0.27	37.2 (34.6)^b	24.7 (15.4)^c	0.05

Esophagitis (n = 28), Idiopathic Achalasia (n = 8), Chagas’ Disease (n = 37), and Controls (n = 31). The results are reported as mean (SD). ^ap < 0.05 vs esophagitis, controls.
Controls	2.5 (0.7)	2.6 (0.9)	0.75	3.9 (0.8)	3.3 (0.8)	< 0.01
