Esophageal motility changes after endoscopic intravariceal sclerotherapy with absolute alcohol.
Endoscopic sclerotherapy (EST) leads to structural and motility changes in the esophagus; the former are thought to be commoner after EST with absolute 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 motility after EST with AA. Accordingly, we studied patients with portal hypertension before (n = 24) and after (n = 22) variceal obliteration by EST with AA using a water perfusion esophageal manometry system. Contraction amplitude 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). Duration of esophageal contraction in both the proximal and distal esophagus became prolonged in the post-EST compared with the pre-EST group (3.3 +/- 0.8 vs. 5.4 +/- 2.6 and 4.3 +/- 1.1 vs. 6.6 +/- 2.3 s, p < 0.001 for both). Lower esophageal sphincter (LES) pressure was reduced in the post-EST compared with the pre-EST group, although the difference was not significant statistically. Abnormal contraction waveforms were more frequent in the post-EST group. One patient in the post-EST group had persistent dysphagia in the absence 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 associated with motor dysphagia.
