Effect of Esophageal Endoscopic Submucosal Dissection on Motility and Symptoms: A Prospective Study

Table 4

High-resolution manometry data for the group showing increases in symptom scores after endoscopic submucosal dissection.

	Before ESD (mean ± SD)	After ESD (mean ± SD)	value
DCI (mmHg·cm·s)	1614 ± 1258	2255 ± 1717	0.09
CFV (cm/s)	5.0 ± 2.3	3.7 ± 0.5	0.17
IBP (mmHg)	5.9 ± 7.3	4.8 ± 7.1	0.62
IRP (mmHg)	7.2 ± 6.3	9.3 ± 8.2	0.39
DL (sec)	6.5 ± 1.7	7.4 ± 0.9	0.12
PB (cm)	2.3 ± 1.1	2.1 ± 1.2	0.45

All cases were from group B (with circumferential resection of 2/3 or greater). DCI: distal contractile integral, CFV: contractile front velocity, IBP: intrabolus pressure, IRP: integrated relaxation pressure, DL: distal latency, PB: peristaltic breaks.
