N/A Background/Aims: For treating and eradicating bleeding esophageal varices, endoscopic variceal ligation(EVL) is currently acceptable practiced method, however esophageal motility change associated with endoscopic variceal ligation is uncertain. Although Longterm follow-up for rebleeding rate, recurrence rate, complication and survival rate after endoscopic variceal ligation are reported, there is a few report of esophageal motility change after endoscopic variceal ligation. To assess the effect of endoscopic variceal ligation on esophageal function prospectively, parameters measured by pneumohydraulic capillary infusion system, included lower esophageal sphincter(LES) pressure, % LES relaxation, amplitude, duration, velocity and progression of peristaltic waves and dysmotility, were compaired hetween before and after endoscopic variceal ligation in 12 patients with csophngeal varix. Results: Endoscopic variceal ligation has no impact on lower Esophageal sphincter(LES) tone. However, a significant increase in the amplitude of peristaltic waves was observed in the patients at'ter endoscopic variceal ligation in the mid-esophagus(8cm above lower esophageal sphincter: 57.2 ' 19.4 versus 65.7 ' 20.3, l3cm above lower esophageal sphincter; 5S,7 ' 23.8 versus 62.l ' 2I.S). There was no modification of duration, velocity and progression of peristaltic waves or dysmotility. Conclusions: Endoscopic variceal ligation is associated with a increasing esophageal body pressure without the other esophageal motility change. (Korean J Gastroenterol 1995;27:9 -17)
