Uc. Ghoshal et al., Esophageal motility changes after endoscopic intravariceal sclerotherapy with absolute alcohol, DIS ESOPHAG, 13(2), 2000, pp. 148-151
Endoscopic sclerotherapy (EST) leads to structural and motility changes in
the esophagus; the former are thought to be commoner after EST with absolut
e alcohol (AA), which is a commonly used sclerosant in India as it is cheap
and effective. There are no previous studies on changes in esophageal moti
lity after EST with AA. Accordingly, we studied patients with portal hypert
ension before (n = 24) and after (n = 22) variceal obliteration by EST with
AA using a water perfusion esophageal manometry system. Contraction amplit
ude in the distal esophagus was reduced in the post-EST group compared with
the pre-EST group (63.4 +/- 24.9 vs. 18.2 +/- 14.3 mmHg, p < 0.01). Durati
on of esophageal contraction in both the proximal and distal esophagus beca
me prolonged in the post-EST compared with the pre-EST group (3.3 +/- 0.8 v
s. 5.4 +/- 2.6 and 4.3 +/- 1.1 vs. 6.6 +/- 2.3 s, p < 0.001 for both). Lowe
r esophageal sphincter (LES) pressure was reduced in the post-EST compared
with the pre-EST group, although the difference was not significant statist
ically. Abnormal contraction waveforms were more frequent in the post-EST g
roup. One patient in the post-EST group had persistent dysphagia in the abs
ence of endoscopically documented stricture at the time of manometric study
. This study shows frequent occurrence of esophageal dysmotility after EST
with AA; however, esophageal dysmotility after EST was infrequently associa
ted with motor dysphagia.
